SUMMARY
The purpose of this SBIR research project is the development, testing and feasibility evaluation of Envirofilter, a versatile point-of-use (POU) filter for home water treatment manufactured from granular activated carbons (GACs). The GACs are produced from select agricultural by-products subjected to special a combination of physical, chemical and thermal treatments to create an adsorption matrix with maximum affinity for both organic and inorganic compounds found in drinking water.
Eight prototype filters using 100% agricultural by-product-based carbons (Envirofilter) were constructed and tested. These included filters made of individual and binary mixtures of acid and steam activated nutshells (pecan, almond, and English walnut). The outcome of testing the Envirofilter prototypes showed that most Envirofilter prototypes were as efficient as the leading commercial filters in removing select metals (copper, lead and zinc) and organics (chlorination byproducts). The Envirofilter is shown to be highly effective in removal of the largest number of contaminants, being of low cost and high durability, and having sound characteristics such as breakthrough and adsorbent dosage/depth for the broadest spectrum of common drinking water contaminants.
The Envirofilter can provide consumers with an efficient, low cost and reliable capability for purification drinking water while helping to preserve the environment through conversion of agricultural wastes into value added products and replacement of short-lived and costly petroleum-based ion exchange resins currently used in drinking water purification. The commercial viability of the Envirofilter was shown through comparison of the effectiveness of select by-product-based activated carbons and major commercial home water treatment systems in removing select inorganic and organic compounds..
Custom-designed Envirofilter has high commercialization potential in drinking water purification at homes in rural communities and towns. Other potential markets include wastewater and storm water treatment, environmental remediation of polluted water streams, and food purification and recycling (e.g., recycling of frying oils generated by the food and food service industries).

Abstract
Foundational innovations in connectivity technologies were developed for the warfighter network; especially the Airborne Network (AN) to effectively increase the digital bandwidth to wirelessly connected users. The innovations involve wireless networking architectures and initial designs that provide high bandwidth, energy efficient, communication links between disparate wireless networks; the best two routing algorithms and projected throughput enhancement from their use; and approaches to model and simulate their performance. The innovative applications of radio and networking technologies are based on exploitation of the dense concentrations of wireless users to support high bandwidth but bursty applications such as image and video transfers. Communication between ad hoc networks containing nodes of disparate types can be accommodated by fitting some nodes with multiple radios, in order to bridge the different node types. Route discovery in the next-generation ad hoc routing protocol takes into account the types of nodes involved in a transmission, to ensure that communication between the endpoints is possible.
SUMMARY
The Phase I SBIR Project is aimed at the development, design, prototyping, and feasibility estimates of mobile ad hoc wireless networking (MAWNET); using networking connectivity technologies for the warfighter. Emphasis will be placed on the special requirements of the IP airborne network (IP-AN), including diversity of devices and links, the high speed of movement, very low resident time in the network and the vast distances between nodes. This involves definition of wireless networking architectures and initial designs that provide high bandwidth, energy efficient, communication links between disparate wireless networks; identification of the best two routing algorithms and projected throughput enhancement from their use; provision of approaches to model and simulate the performance of the routing algorithms for the IP-AN; examination of the feasibility of the new systems; and development and design of prototype systems that effectively increase the digital bandwidth to wirelessly connected users and enable energy efficient, reliable, low-latency and self-healing ad-hoc networking amongst heterogeneous devices in the IP-AN including at least one JTRS compliant device. This is considering that a large base of the installed legacy networks will coexist with new equipment.
The connectivity technologies for the warfighter network shall exploit the dense concentrations of wireless users to support high bandwidth but bursty applications such as VoIP and image and video transfers. This would have the benefits of globally conserving energy as well as increasing the effective bandwidth of the system while maintaining high reliability and availability of the network, assurance of self heeling and very low latency. Nevertheless, the energy conservation approach shall also respect the local needs of individual devices (e.g., not penalize a device that is in an advantageous relay location).
The definition of wireless airborne networking architectures as well as the selected initial designs of prototype systems have been shown to be technically feasible through modeling and simulation of the IP-AN. The most appropriate routing algorithms were the Dynamic Source Routing (DSR) protocol and the R-ODMRP (a special reliable modification of the On-Demand Multicast Routing Protocol (ODMRP)). RODMRP is considered for handling the extremely fast moving nodes (fighter jets). A routing algorithm that integrates metrics beyond hop counts during route discovery, such as the Implicit Source Routing (ISR), an improved version of DSR, may be used in place of DSR for on-demand ad hoc network routing, since ISR removes much of the overhead of the standard DSR. However, the basic functionality of ISR is similar to DSR and the results for DSR carry over to ISR.
The basic features of the identified protocols are expected to support a next-generation ad hoc routing protocols as demonstrated through analysis of existing ad hoc routing protocols and to support improved power management, better throughput for unicast and multicast communication (by utilizing multiple routes simultaneously), and to provide better reliability.
The simulation showed that DSR holds up under many mobility scenarios, including movement of terrestrial nodes at 40 mph or more. In the simulations, occasionally a shorter route gets chosen (since DSR always uses the shortest route) that may immediately break because at least one link is at the edge of the radio range. Basically, sometimes a short route is available, but at least one of the links is very weak. In very dense networks, simply choosing the shortest path is not the optimum choice since there will be a lot of overlap. A longer route with strong signals on each link might be more viable. In addition the edge conditions where the DSR protocol falls apart must be found.
Scenarios were developed to handle very fast moving nodes and to test the edge conditions where the routing protocols fall apart. The simulation showed that interactions of very high speed “visiting” nodes with airborne and terrestrial tiers are problematic, as expected. Accordingly, initial formulation of plans for handling very high speed nodes involves store and forward strategy in the airborne tier.
The development of the final prototype systems requires addressing the very fast-moving nodes, by expanding and implementing the store and forward strategy model, including incorporation of the Model/Protocol in OPNET; exporting of topology generating tool Bessie to OPNET Modules, adapting the ISR Protocol to OPNET, integrating the flight patterns into airborne tier routing, eliminating the ground-to-ground network contention, integrating the design; and analyzing reliability, energy conservation efficiency and bandwidth.
Demonstration of the prototype system should employ scenarios for mobile wireless ad hoc networking considering present and future AN; based on planned applications of the IP-AN, especially in the battle-field. Formation of real scenarios can be based on well-documented scenarios of past wars and anticipation of the role of the IP-AN, in future wars.
The Network Centric Operations Industry Consortium (NCOIC) anticipates ample commercial applications for the connectivity of AN. Direct commercial applications of the IP-AN connectivity include large commercial enterprises that may share some of the attributes of the military system; such as mining operations in extended areas of complex topography. This is in addition to rescue and relief missions during devastating natural disasters that cover a wide spread terrain; such as the EXXON Valdez oil spill in Alaska, the tsunami in Southeast Asia, and Hurricanes Katrina and Rita in the Gulf of Mexico region wherein all communication means were destroyed and the communications via cellular phones and land based phones were interrupted whether between citizen or between emergency and law enforcement personnel. In response to the loss of communication that followed the move of Katrina to the land, the City of New Orleans has decided to build a wireless network infrastructure covering the whole City. This is to help recovery crews to easily communicate via multimedia network from any locations. In anticipation of future storms, the products can be employed during rescue efforts.
The first commercial product of this technology should go into is a homeland security system; specifically a mobile ad hoc wireless networking system for rescue missions during national or regional disasters whether manmade or natural disasters such as Katrina and Rita Hurricanes. This may immediately follow the transition of the fully developed systems to the Air Force. The customers in this case include: DHS (FEMA), State Governments, Parish/County emergency organizations, NIST (DOC), mining industry, organizations engaged in rescue operations including the National Guard as well as international rescue organizations and the UN.
The potential military applications resulting from a store and forward system for the airborne tier include direct use in combat with fighter jets zipping in and out sending/ receiving VoIP, image and video packets to/from big ISR platforms. This would also have extensive application to homeland defense initiatives for network interoperability and increased information throughput as well as the National Airspace System (NAS) in providing a means of positive identification of an aircraft and its altitude in the air traffic control system. Furthermore, the results would benefit the FAA. If aircrafts utilized IP as network computers do, functions in the cockpit could be enabled not currently being provided. It could open up a whole new set of operating capabilities, safety and efficiency for tomorrow’s aviation industry. The functions provided today that require the use of multiple on-board systems could be reduced to two simple systems. Applications include operations and maintenance: engine monitoring, crew communications, fault reporting, and diversion management; cabin services: internet access, and programming distribution; air traffic management: system capacity (separation), hazardous weather avoidance, collaborative decision making, and position reporting; and safety & security: transportation security, real time black box transmission, and telemedicine. Airborne Internet is a vital element in the Next Generation Air Transportation System (NGATS). In the Aerosat Airborne Internet Demonstration, broadband communications over 1000 times as fast as standard 64K satellite service, operating at a small fraction of the cost.
The potential military and commercial applications of the prototype systems include building future capabilities from the foundational innovation of the outcomes of this project; especially on-demand network access and handling flexible networks that dynamically change configuration based on mission, commander’s intent, and security requirements.

SUMMARY
This Phase II SBIR Project is aimed at the development, design, prototyping and demonstration of mobile ad hoc wireless network (MAWNET) connectivity technologies for the warfighter. A set of airborne nodes form a virtual backbone that enables long-range, multi-hop communication between groups of terrestrial nodes, without extensive fixed infrastructure. Emphasis are placed on the special requirements of the IP airborne network (IP-AN), including diversity of devices and links, high speed movement, very low resident time in the network and the vast distances between nodes. This involves definition of wireless networking architectures and designs that provide communication links between disparate wireless networks; identification of the best routing algorithms and projected throughput enhancement from their use; provision of approaches to model and simulate the performance of the routing algorithms for the IP-AN; and development and design of prototype systems that effectively increase the digital bandwidth to wirelessly connected users and enable energy efficient, reliable, low-latency and self-healing ad-hoc networking amongst heterogeneous devices in the IP-AN including at least one JTRS compliant device. This is considering that a large base of the installed legacy networks will coexist with new equipment.
Our prototype is a hybrid design that fuses OLSR (Optimized Link State Routing), a proactive routing protocol, with DSR (Dynamic Source Routing), a reactive routing protocol. Airborne nodes are routed proactively with OLSR, with very high-speed airborne nodes (e.g., jet fighter planes) being temporary members of the airborne tier for only short periods of time. In the terrestrial tier, nodes are routed reactively on a local (cluster) basis, with the airborne tier providing a backbone to connect the terrestrial clusters. Communication between nodes in distinct terrestrial clusters uses a tunneling scheme to tunnel DSR packets between the clusters. Distinguished nodes with dual wireless interfaces (one interface for terrestrial-to-airborne and one interface for cluster-local communication) provide connectivity between terrestrial and airborne tiers and are responsible for tunneling and de-tunneling operations.
We developed scalable, fault-tolerant, hierarchical naming schemes for terrestrial nodes that allow multiple dual-interface nodes per cluster, tolerate movement of terrestrial nodes between clusters and require minimal overhead. The naming schemes involve assignment of first class names to airborne nodes and to the dual-interface, terrestrial nodes. Terrestrial nodes are located either through a distributed registration process or via cluster-local “hello” messages that introduce terrestrial nodes to nearby distinguished nodes. Both schemes require multiple dual-interface nodes in a single terrestrial cluster to cooperate so that communication is maintained seamlessly if one or more of the dual-interface nodes fail.
Phase I work defined wireless networking architectures and initial designs that provide high bandwidth, energy efficient, communication links between disparate wireless ac hoc networks and identified the most appropriate routing algorithms. Extensive modeling and simulation led to a preliminary design that enables energy efficient, ad-hoc networking amongst heterogeneous devices in the IP-AN.
Subsequently, Phase II is geared towards demonstration of a prototype hybrid routing scheme. This encompasses dual-interface wireless node type, capable of handling two distinct routing protocols, one for a terrestrial routing tier comprised of nodes with relatively low mobility rates and one for an airborne tier comprised of both backbone nodes (that provide a stable network backbone) and special transient node types (with high-speed nodes being of particular interest). The dual-interface nodes have the ability to participate in and route traffic between both proactively and reactively routed tiers, tunneling control and data traffic as needed; thus bridging the two routing tiers, providing appropriate routing mechanisms for each tier and allowing efficient communication between tiers.
Our approach uses a hybrid routing strategy, with clusters of nodes in the terrestrial tier using a reactive routing scheme to establish intra-cluster communication routes. Nodes in the airborne tier use a proactive routing scheme, with the airborne tier providing a virtual backbone for the terrestrial clusters. Our approach is simulated in the OPNET network simulator. Implementation of the approach required implementation of dual-interface nodes that are capable of running both reactive and proactive routing protocols (to bridge airborne and terrestrial tiers), investigation of appropriate hierarchical node naming schemes, and development of a tunneling protocol to move data and control messages between the airborne and terrestrial tiers.
Modeling and simulating our prototype architecture in OPNET required implementation of the dual interface node models within OPNET via modification of several library modules. Since OLSR and DSR packets originate at different layers (UDP vs. IP), it is necessary to modify not only the implementation of OLSR and DSR within OPNET, but also to provide a common packet “meeting point” for both types of packets in the OPNET module which handles IP routing, where we can not only integrate the two routing techniques (e.g., provide for packet tunneling when necessary, integrate route discovery, etc.) but also monitor and hijack packets, as necessary.
The innovative applications of networking technologies in our work serve to effectively increase the digital bandwidth to wirelessly connected users and enable energy efficient ad-hoc networking amongst heterogeneous and geographically diverse devices, including JTRS compliant devices.

Abstract
This report presents the development, design, prototyping, and demonstration of innovative wireless connectivity technologies for the warfighter mobile ad hoc network. Emphases are placed on the special requirements of the IP airborne network (IP-AN) including diversity of devices and links, high speed of movement, very low resident time in the network and the vast distances between nodes. The innovative applications of networking technologies are directed to effectively increase the digital bandwidth to wirelessly connected users and enable energy efficient communication links between disparate wireless networks and ad-hoc networking amongst heterogeneous devices, including JTRS compliant devices. This is considering that a large base of legacy networks installed that will coexist with new equipment, such as that based on DoD’s JTRS, for decades. The connectivity technologies for the warfighter network exploit the dense concentrations of wireless users to support high bandwidth but bursty applications, such as VoIP and image and video transfers. This would have the benefits of globally conserving energy as well as increasing the effective bandwidth of the system while maintaining high reliability and availability of the network, assurance of self-healing and very low-latency.
SUMMARY
This Phase II SBIR Project is aimed at the development, design, prototyping and demonstration of mobile ad hoc wireless network (MAWNET) connectivity technologies for the warfighter. A set of airborne nodes form a virtual backbone that enables long-range, multi-hop communication between groups of terrestrial nodes, without extensive fixed infrastructure. Emphasis are placed on the special requirements of the IP airborne network (IP-AN), including diversity of devices and links, high speed movement, very low resident time in the network and the vast distances between nodes. This involves definition of wireless networking architectures and designs that provide communication links between disparate wireless networks; identification of the best routing algorithms and projected throughput enhancement from their use; provision of approaches to model and simulate the performance of the routing algorithms for the IP-AN; and development and design of prototype systems that effectively increase the digital bandwidth to wirelessly connected users and enable energy efficient, reliable, low-latency and self-healing ad-hoc networking amongst heterogeneous devices in the IP-AN including at least one JTRS compliant device. This is considering that a large base of the installed legacy networks will coexist with new equipment.
Our prototype is a hybrid design that fuses OLSR (Optimized Link State Routing), a proactive routing protocol, with DSR (Dynamic Source Routing), a reactive routing protocol. Airborne nodes are routed proactively with OLSR, with very high-speed airborne nodes (e.g., jet fighter planes) being temporary members of the airborne tier for only short periods of time. In the terrestrial tier, nodes are routed reactively on a local (cluster) basis, with the airborne tier providing a backbone to connect the terrestrial clusters. Communication between nodes in distinct terrestrial clusters uses a tunneling scheme to tunnel DSR packets between the clusters. Distinguished nodes with dual wireless interfaces (one interface for terrestrial-to-airborne and one interface for cluster-local communication) provide connectivity between terrestrial and airborne tiers and are responsible for tunneling and de-tunneling operations.
We developed scalable, fault-tolerant, hierarchical naming schemes for terrestrial nodes that allow multiple dual-interface nodes per cluster, tolerate movement of terrestrial nodes between clusters and require minimal overhead. The naming schemes involve assignment of first class names to airborne nodes and to the dual-interface, terrestrial nodes. Terrestrial nodes are located either through a distributed registration process or via cluster-local “hello” messages that introduce terrestrial nodes to nearby distinguished nodes. Both schemes require multiple dual-interface nodes in a single terrestrial cluster to cooperate so that communication is maintained seamlessly if one or more of the dual-interface nodes fail.
Phase I work defined wireless networking architectures and initial designs that provide high bandwidth, energy efficient, communication links between disparate wireless ac hoc networks and identified the most appropriate routing algorithms. Extensive modeling and simulation led to a preliminary design that enables energy efficient, ad-hoc networking amongst heterogeneous devices in the IP-AN.
Subsequently, Phase II is geared towards demonstration of a prototype hybrid routing scheme. This encompasses dual-interface wireless node type, capable of handling two distinct routing protocols, one for a terrestrial routing tier comprised of nodes with relatively low mobility rates and one for an airborne tier comprised of both backbone nodes (that provide a stable network backbone) and special transient node types (with high-speed nodes being of particular interest). The dual-interface nodes have the ability to participate in and route traffic between both proactively and reactively routed tiers, tunneling control and data traffic as needed; thus bridging the two routing tiers, providing appropriate routing mechanisms for each tier and allowing efficient communication between tiers.
Our approach uses a hybrid routing strategy, with clusters of nodes in the terrestrial tier using a reactive routing scheme to establish intra-cluster communication routes. Nodes in the airborne tier use a proactive routing scheme, with the airborne tier providing a virtual backbone for the terrestrial clusters. Our approach is simulated in the OPNET network simulator. Implementation of the approach required implementation of dual-interface nodes that are capable of running both reactive and proactive routing protocols (to bridge airborne and terrestrial tiers), investigation of appropriate hierarchical node naming schemes, and development of a tunneling protocol to move data and control messages between the airborne and terrestrial tiers.
Modeling and simulating our prototype architecture in OPNET required implementation of the dual interface node models within OPNET via modification of several library modules. Since OLSR and DSR packets originate at different layers (UDP vs. IP), it is necessary to modify not only the implementation of OLSR and DSR within OPNET, but also to provide a common packet “meeting point” for both types of packets in the OPNET module which handles IP routing, where we can not only integrate the two routing techniques (e.g., provide for packet tunneling when necessary, integrate route discovery, etc.) but also monitor and hijack packets, as necessary.
The innovative applications of networking technologies in our work serve to effectively increase the digital bandwidth to wirelessly connected users and enable energy efficient ad-hoc networking amongst heterogeneous and geographically diverse devices, including JTRS compliant devices. The connectivity technologies for the warfighter network will exploit the dense concentrations of wireless users to support high bandwidth, bursty applications such as VoIP and image and video transfers. Improved networking technologies for the IP Airborne Network will benefit both the DoD's objectives for the JTRS program and have extensive applications to homeland defense initiatives for network interoperability and increased information throughput.
The ad hoc connectivity technology can be leveraged into air traffic and sea navigation expeditions; large scale events such as disaster relief or rescue efforts in a natural disaster area struck by earthquake or hurricane; community networks in dense residential areas and large scale, long-range networks; and can be adapted in the Automatic Dependent Surveillance - Broadcast (ADS-B) being under development.

SUMMARY
This project addresses the development and feasibility evaluation of the capabilities of SoftDASh (software differential analysis shield) an innovative concept which comprises robust, low cost tools and methodologies for countering differential analysis. The SoftDASh was conceptualized to mitigate the threat of differential analysis, a specific type of reverse engineering, can help pinpoint the locations of changes across released versions of software, potentially allowing newly introduced security features to be more easily defeated.
Starting with specification of the design, implementation and performance requirements of the SoftDASh, in light of the particulars of the topic and the outcome of the kickoff briefing by the AFRL/SN AT-SPI Technology Office; criteria for evaluation of the known differential analysis techniques are developed. Metrics for evaluation of the technical feasibility and commercial viability of the SoftDASh are established based on the general and specific requirements.
A review of the differential analysis techniques showed varying degrees of vulnerability to differential cryptanalysis, differential power analysis, differential time analysis, differential electromagnetic analysis, differential fault analysis, and differential software analysis (DSA) that can incorporate other techniques. Some of the techniques are dependent on penetration of access controls. The strength of the techniques is evaluated showing that DSA is the strongest, given familiarity with earlier versions of the codes or partial access to their modules.
Several software differential analysis techniques were examined to identify the strengths and weaknesses of each technique. Those techniques include: physical protection, wrapping executables, code obfuscation, watermarking and TCPA (Trusted Computing Platform Alliance). Some of the programs that were or being reviewed are: Armadillo (wrapping) and SandMark (watermarking and obfuscation). Under consideration is Cloakware (obfuscation).
We have developed a technique based on extracting key program data from sensitive applications, such as tables of floating point values (e.g. physical properties, material properties, mesh size, etc. which are essential for the computation at hand) and encrypt the data using a machine-specific key. The program data can then be decrypted only on the targeted machine.
COTS wrappers and obfuscation techniques fall short of providing complete protection against differential analysis; whether directly applied or modified. The recommended tools can be implemented in a redundant and diverse fashion to provide the required protection. Here, different ways of using a physically protected server in a cluster computation are presented. Multiple tools relying on diverse techniques are required to provide assured protection using SoftDASh.
Several mechanisms for using a physically protected server in a cluster computation to thwart differential analysis attacks were examined. We envision wrapping technologies as a first level of defense against differential analysis attacks—to prevent an attacker from examining an application’s codes. If first level protection is compromised, for example, if the wrapping technology is defeated, then other measures should be in place. We believe that placing critical application data on a physically secure, remote server (or on a local machine inserted into a cluster, as described in our earlier report on our prototype using the encryption chip in IBM Thinkpad computers) is a good second level of defense. Even if the first level is breached, access to critical data (e.g., tables of empirically-determined constants) is available only through application-endorsed communication with a physically secure server. This server can be hardened against brute-force enumeration attacks by introducing timeouts, auditing communication with particular clusters, or a related mechanism. In the extreme case, the physically secure server might return incorrect values if a brute force enumeration attack is noticed.
We have written and modified a cluster application to access a physically secure server to perform table lookups. Our proof of concept for inserting a secure server component into a cluster application is quite simple, but we believe it illustrates the important concepts. We have modified a cluster-based, z-buffer based rendering engine to perform lookups of textual color names against a secure server. For example, “goldenrod” maps to the RGB triple (0.855 0.647 0.125). The color lookup table on the server comprises some 600+ entries and the secure server implements authentication (username/password) and timeouts to discourage enumeration attacks.
The technical feasibility of the structure of the SoftDASh innovative tools and methodologies were evaluated in terms of countering most or all of the plausible differential analysis techniques and a multi-layer system was provided.

SUMMARY
The use of stored electricity is minimal in today's Air Force, due to low ac/dc conversion efficiencies, and high power loss during dc storage, high cost, and high density per kW. With an overall efficiency approaching 95 percent, SMES has the potential to meet Air Force power storage requirements. The benefits and the suitability of SMES units specifically for Air Force applications are numerous providing that concepts compatible with each or most applications can be developed and validated. In this report candidate configurations are provided and required validation tests are proposed for a new dc/dc converter. The product is characterized by high efficiency; light-weight components and supporting systems, including the conductor, the structure, the containment vessels and all auxiliary systems; flexible outputs; low heat leak; and tolerance for dynamic loading during take off, landing, or emergency maneuvers.
A feasible configuration based on a solenoid design was developed and evaluated for a 1 MW system for the Air Force. Alternative toroid design was described and also evaluated for low losses.
A SMES unit can be used as a power supply and can be sized for transportation. e.g., in a C-5 plane and designed to be operational within three days of deployment. A typical 2000 man Air Force-unit would require about 3 MW of average power. The SMES would be used to help provide station-keeping energy storage power 24 hours per day on a continuous basis. Smaller units can be also used for other mobile Air Force base applications. Applications of the product are numerous, in future Air Force operations, and will have wide range of applications in all Department of Defense (DOD) components, the aviation, aerospace, processing industry as well as other commercial applications in low to medium demand on energy storage.
A feasible SMES will increase the use of stored electricity in the Air Force. Efficient, low cost storage systems are needed for various applications by all DOD-components. Commercial demands from vehicles to power industry are limitless. Possible uses as mobile or airborne energy storage units are compatible with both military and civilian environments.
A 1 MW Superconductive Magnetic Energy Storage system (SMES) with 100 kWh energy stored is considered as a baseline design for this study. Design details, component specifications, power conditioning, and estimated cost are included. The SMES meets the U.S. Air Force power storage requirements with an overall input/output efficiency (ac/dc or dc/dc) better than 95 percent, low/minimal power loss during dc storage, low cost, and high power density. The design and manufacturing of such a system will increase the use of stored electricity in the Air Force, which is minimal in today's Air Force. In addition these units can be used as highly mobile, rapidly deployable combat forces quickly responding to dynamic battle field situations.
An important part of SMES usage, as high power density source, is the power conditioning component that connects SMES to the required load. In this report, we concentrate on newly developed ideas in dc/dc conversions that have the advantage of high efficiency, flexibility of power control and low cost.
The converter circuit appears to have potential applications in the cases where the dc current of a constant current source such as SMES coils needs to be stepped up or down. The advantages of this circuit can be summarized as follows:
1)Output voltage and current can be held constant during the operation though the input current from the current source may drop because the input energy source is finite in size. This can be accomplished by either controlling the switching time or/and changing the transformer ratio, N.
2)Ease of power control at the output side through changing the capacitor voltage.
3)High efficiency is possible if the switching time of S1 and S2 is kept above 0.5 tC. By using highly coupled transformer (k>0.95), the efficiency is always better than 90 percent. The losses occur in the resistors across the switches. In case switches are placed at cryogenic temperature, small low duty leads can be used to move these resistors to ambient temperature so that the refrigeration power is kept to a minimum.

Patent Abstract
The invention is a detector for detection of concealed explosives, drugs and contraband using x-rays imaging and powder pattern techniques and ultrasonics. In case of inspection of carry-on baggage a combination of computer-aided x-ray transmission imaging and x-ray diffraction analysis is used to screen, confirm and localize threats. The x-ray transmission is used to segregate dense baggage and cargo which are inspected by x-ray backscatter imaging to identify suspicious objects.

SUMMARY
A critical technology effort explored the viability of applying advanced non-destructive testing methods in detection of explosives. The assessment was followed by screening technologies which are impractical or do not meet the requirements. Out of the screened technologies, optimal alternative strategies were defined to develop a concept for the RSDC. The selected technology was the use of prompt gamma nuclear detector and x-ray backscattering. Consideration of using gas chromatography as a second tier was shown to have promise. The formulated concept was analyzed and evaluated. Plans for demonstration were also made.

Patent 2 Abstract
A system and process for neutralizing unexploded ordinances and clearing explosive infested areas such that maneuvers can be both readily and confidently continued without significant delay is disclosed. The system clears such unexploded ordnances infested areas by initially spraying the explosive infested area with a cryogenic liquid to neutralize the unexploded ordinances and reduce an output voltage of a detonator of the unexploded ordinances thereby rendering the unexploded ordinances inert, gathering the now unexploded ordinances and submerging the inert unexploded ordinances in a tank containing the same or similar cryogenic liquid so that the unexploded ordinances are maintained in a neutralized and inert state to allow for disposal. Alternatively, the neutralization of unexploded ordinance and clearing of explosive infested areas may be carried out by spraying the explosive infested area with liquefied methane to neutralize the unexploded ordinance and reduce an output voltage of a detonator of the unexploded ordinances to render such ordinance inert, igniting the liquefied methane, deflagrating the unexploded ordinances at a temperature less than that required for detonation and subsequently removing the neutralized ordinances from the explosive infested area.

SUMMARY
A hand-held mine and explosives detection capability employing x-rays (MINEDECX) was developed based on dual-energy x-ray backscatter imaging. The capability was developed for eventual fabrication and troop demonstration of an antipersonnel mine detection system capable of real time operation, at normal troop advance rates; high efficiency; high detection/false target ratios (signal-to-noise ratio); high reliability; negligible miss incidents; and low mass and manufacturing cost. The operation of the MINEDECX provides sufficient standoff to avoid engaging a detected mine.
A preliminary design was established at the onset of the program and then refined, using computer simulation into a baseline proof-of-concept (BPOC) design. Analytical and experimental verification demonstrated the capability of the BPOC to penetrate the soil cover and distinguish between typical mines and the background. The use of dual-energy and multiple displaced detectors demonstrated the ability to provide the desired scanning for foot soldiers without interference from rough surfaces and irregularities in the terrain.
The detector consists of a 20kW rotating anode x-ray generator which switches between two x-ray energies at a rate of 60 switches/sec. An oscillating collimator sweeps across an area of 60 cm at a rate of 1 sweep/sec, that is a forward speed of 120 cm/min can be achieved. Four scintillation detectors with an area of 20 cm2 each are displaced at differing heights. Both the source and detectors will be located approximately 30 cm above the surface.
The MINEDECX differentiates between mines and other objects both by the backscattering intensity and the image appearing on the CRT. Hence, the detector capability can differentiate between a piece of wood and a mine due to the higher intensity of the backscattering detected from the wood (because of the low density) as well as the shape of the object. The BPOC is designed for detection of a mine at depths in the range form 0 to 8.5 cm. An opportunity for a miss or false alarm will arise only if the mine is buried deeper than the range specified for the detector or if the mine is masked by a large rock of the same image and density of the mine. To enhance the discrimination between mines with metallic casings and pieces of metallic debris, such as shells, a metallic detector may be used in parallel with the MINEDECX to provide redundant capability.
The use of more than two switching energies would add unnecessary complexity with no significant increase in the sensitivity of the hand-held antipersonnel mine detector. However, to provide a capability to detect deeply buried mines buried at depths in excess of 8-10 cm as well as surface mines, multiple energies may be useful.
Based on the BPOC design a prototype can be constructed at a reasonable cost using a two rotating anode set for scanning a foot path. The prototype would be physically supported by an all terrain vehicle (ATV) which carries the power supply and a microprocessor. The ATV support will minimize the load of the dismounted troops to allow for ease of movement, sweeping, and observation. The ATV would also provide a physical shield from the scattered x-ray radiation in addition to a lead apron to assure safety of the soldier. The prototype can be prepared for troop demonstration.
All components of the mine detection capability are off-the-shelf items which can be constructed in a manner appropriate for troop use. The switching system is simple and relatively light generators are available. Several future developments can be introduced after prototype demonstration to increase the range of detection and to extend the application to various types of mines.

SUMMARY
This project addresses the development of working models of WLAN DesAnVal, a suite of Wireless Local Area Network (WLAN) Design and Validation (survey) tools to reduce the time and effort spent in what is currently a trial and error process for each installation. The tools are developed for use during a site survey in complicated military environment where there is vulnerability to security, electromagnetic interference (EMI), radio frequency interference (RFI), and ordnance.
EMI/RFI generators on platforms, such as electronic equipment, microwave ovens, and rogue APs that will degrade the performance of the WLAN if not compensated for in the design. Military environments with steel walled compartments can be very difficult when it comes to positioning RF equipment, due to obstructions and combinations of both large and small spaces.
The WLAN DesAnVal capability encompasses: (1) a survey tool that uses a directional antenna to determine, measure, and locate sources of EMI/RFI in the 802.11a/b spectrums; (2) a survey tool to determine when multi-path interference (MPI) will be encountered; (3) aid in determining a method to eliminate/reduce the impact of EMI/RFI/MPI on the WLAN; (4) a tool to generate traffic at adjustable rates (packets of adjustable size) and measure the throughput, errors, and collisions between any two points on the WLAN; and (5) measure the nominal transfer rates of the most commonly used Internet Protocols (IPs); such as the Transmission Control Protocol (TCP), User Datagram Protocol (UDP), and Internet Control Message Protocol (ICMP) between certain critical points in the WLAN, such as uplinks to core and distribution devices or between clients and Access Points (APs).
The working models of the WLAN DesAnVal tools comprise adapted state-of-the-art Components-Of-The-Shelf (COTS) as the hardware tools and mapping software for site survey, in addition to custom-made software tools for traffic generation, site mapping augmentations, and link analysis for pre-survey planning and survey validation. All tools are selected and/or developed to work in complex military environments, are optimized for minimal life-cycle costs and are geared to provide the basis for development of an integrated WLAN DesAnVal prototype level functioning tool.
Production level products of the WLAN design and validation tools have value in both of the commercial and government sectors. The WLAN DesAnVal tools especially meet the needs of Navy ships, military mobile platforms, Army proving grounds, and commercial boats. Potential commercial applications encompass military bases, the defense industry, NASA repair and maintenance shops, nuclear facilities, chemical and petrochemical industries, factory floors, communication and data transfer between downstream and upstream operations in factories and assembly lines.

SUMMARY
The general objective of this project is aimed to develop, design and evaluate the technical feasibility and commercial viability of an innovative potable water capability that produces 800 gallons per day (gpd) potable water from littoral waters sources in harbors, rivers, inlets, bays, landlocked waters, and the open sea within 12 nautical miles from the entrance of these waterways. The size of the conceptualized drinking water system fits on the smaller platforms the Navy uses in the littoral waters, such as a 135' Landing Craft, Utility (LCU). The process is capable of removal of pollutants commonly found in littoral waters, such as pesticides, arsenic and other chemicals. The feed water is of unknown quality. The quality of the product water is that of potable water that meets the National Primary Drinking Water Standards and the EPA National Drinking Water Standards. This can be achieved with a pretreatment unit compatible with the variability of the chemical and physical composition of the pollutants in the littoral waters and the extent of the pollution. The system comprises the following major subsystems:

The process is capable of removal of pollutants commonly found in littoral waters, such as pesticides, arsenic and other chemicals. The feed water is of unknown quality. The quality of the product water is that of potable water that meets the National Primary Drinking Water Standards and the EPA National Drinking Water Standards. This can be achieved with a pretreatment unit compatible with the variability of the chemical and physical composition of the pollutants in the littoral waters and the extent of the pollution. The system comprises the following major subsystems:
- RO unit
- A unique freezing purification pretreatment stage to provide a feed of known quality for the RO from the littoral water source.
- On-line ultrasonic membrane cleaning for the RO to assure continuous uninterrupted operation during emergencies.
- Realtime verification of potable water quality.
- Polishing unit to assure meeting the EPA standards.

SUMMARY
This Final Report addresses the outcome of the Phase I efforts, which involved investigation of the mechanisms of membrane fouling in wastewater applications; investigation of viable concepts to continually, and in a non-invasive manner, clean the membrane surface during processing; development of the ultrasonic technique; and planning for demonstration of the low energy non-invasive ultrasonic method for membrane cleaning on a bench-scale membrane-based wastewater treatment process.
A proof-of-concept (POC) test rig of the ultrasonic cleaning mechanism was designed and implemented for feasibility evaluation of the approach. The test assembly was constructed by placing an ultrasonic probe on the feed side of a hollow fiber membrane module, near to the cross-flow outlet. The membrane effective surface area is @ 1.8 m2 and the fibers are 200µm internal diameter and 40µm wall thickness. Several experimental runs were made, in the POC test on different water and wastewater streams, including navy graywater specifications composite mix of ship waste stream consisting of food service (galley), laundry, and washroom waste, which can be reproduced in the laboratory. Test runs were conducted first without the use of the ultrasonic cleaning device. The test runs were repeated using the ultrasonic assembly. The results of the POC tests showed that the most effective cleaning takes place in the portion of the module facing the ultrasonic probe throughout the test. Based on these results, a bench-scale membrane-based wastewater treatment process will be rigged with the ultrasonic cleaning mechanism and proper redesign and modifications of the membrane modules will be made to demonstrate the capability of the low energy, non-invasive ultrasonic method for membrane cleaning and to prepare for transition to the Navy's Advanced Development Program.
Proper placement of multiple ultrasonic transducers to cover the whole volume of the membrane module, near the retentate outlet, with the emitted ultrasonic waves would deliver the desired cleaning to all the fibers exposed to the ultrasonic waves. The results of the analysis of the test data demonstrated that the ultrasonic method has the potential of maintaining near initial membrane flux during the lifecycle of the process, and subsequently would decrease the size of a treatment system as a result of increased production per square foot of membrane surface area.
The ultrasonic cleaning of membranes will provide vast benefits to the numerous installations using membrane separation in the wastewater treatment, biomedical, and chemical industries as well as to wastewater/rawwater installations and skid-mounted units on commercial and Naval ships, on military bases; or on mobile platforms in the battlefield. A substantial reduction in the life cycle cost can be achieved by savings in chemical and mechanical cleaning, reduction of the size of the pretreatment process, and enhancement of the productivity and efficiency of the membrane process.

SUMMARY
This Phase I research effort was directed toward the review of technologies which could be applied to shipboard dishwashing to substantially reduce or eliminate the amount of graywater produced during the cleaning of dishware items aboard Navy vessels. The objectives of this research effort were to examine viable concepts and techniques based on available technologies which could be applied to clean dishes without the generation of graywater or excessive secondary waste streams, to screen the proposed concepts and techniques to identify the most promising technologies, to develop a conceptual design of the optimal process for cleaning dishes, to perform proof-of-concept bench scale tests to determine feasibility of untested components or technologies, and to evaluate the feasibility of the overall concept with a preliminary design of the breadboard model to be constructed in Phase II.
Technologies examined include heated air, steam jets, ultrasonics, blasting, chemical cleaning, physical scrubbing, and the current state-of-the-art water jet cleaning methods. These technologies were screened based on specific decision criteria using a pairwise comparison method. These criteria included environmental impact, degree of cleanliness, operational and maintenance considerations, and integration with current facilities. The study indicated that blasting methods with integrated recycling capabilities would offer the greatest success for cleaning dishware items while considerably reducing the graywater and secondary waste stream production.
Laboratory tests were performed to validate the feasibility of using blasting methods to clean dishes and utensils. Operational considerations were outlined and preliminary system designs were developed.
Patent 1 Abstract
The invention is a detector for detection of concealed explosives, drugs and contraband using x-rays imaging and powder pattern techniques and ultrasonics. In case of inspection of carry-on baggage a combination of computer-aided x-ray transmission imaging and x-ray diffraction analysis is used to screen; confirm and localize threats. The x-ray transmission is used to segregate dense baggage and cargo which are inspected by x-ray backscatter imaging to identify suspicious objects. All suspicious objects are carefully analyzed by x-ray diffraction. In another embodiment a slow processing system uses diffraction for identification of threats and x-ray radiography for localization of the objects. In case of drugs concealed in compartments aboard marine vessels or air crafts a hand-held x-ray system is disclosed which can be used in three modes of operation: x-ray transmission, x-ray backscatter, or x-ray diffraction dependent on the architecture of the compartment. In case of buried mines an oscillating dual-energy x-ray backscatter imaging is used for antipersonnel mines and a combination of x-ray backscatter imaging and prompt gamma detectors is used for antivehicle and antiaircraft mines. Ultrasonic detectors are disclosed for detection of explosives on persons. Also, a tracking system based on bar-code identification system and a central computer is disclosed for baggage.

Head-Mounted and Wrist-Mounted SOF Tactical Information Displays. TII-VA Report #: TILA-02-SOCOM-07, Contract #: C- USZA22-02-P-0502, U.S. Special Operations Command.
SUMMARY
The goal of this Small Business Innovative Research (SBIR) project is to enhance personal and/or team performance of the Special Operations Forces (SOF) through the effective use of Tactical Information Assistants. The approach is to seek innovative technology ideas, which offer significant added value to current practice and that can be embedded into SOF Tactical Information Displays (STIDs) to allow individual users or teams to receive video signals that provide them with application-specific graphical and alphanumerical information transmitted from a Portable Digital Assistant (PDA) or any SOF operator’s computer using wireless technology.
Aiming at the design, building and demonstration of a family of tactical/military displays for the war-fighter including: wireless wrist-mounted, head-mounted or helmet-mounted and 4" or 6" hand-held STIDs to provide deployed SOF personnel with hands free information, a set of design, construction and performance requirements were developed. Those requirements were used to establish criteria for evaluation of commercially available displays that may be adapted or modified to meet the SOF needs for mission success and for evaluation of the produced STIDs, which are basically low power “remote” displays, similar to computer monitors.
The STIDs have to be rugged, safe, reliable, inexpensive (throwaways), small, lightweight (portable/wearable) remote electronic displays that consume little power (=0.5W to maximum of 1W) and have high resolution (SVGA/XVGA, with 32k colors). The STIDs are powered by internal rechargeable batteries that last a minimum of 6 hours and may last up to 12 hours. An external DC input is used to run with an external power source and/or to charge the internal battery. The wrist-mounted and hand-held STIDs have adjustable luminance, from off (dark) to bright enough to be seen in bright sunlight. The head-mounted STIDs have 32º viewing angle and may take the form of eyeglasses and/or a helmet mounted display. In either configuration, the mounting of the display should not result in interference with any normal team/crew duties.
With the exception of the cost and power consumption, a few displays; whether commercially available-off-the-shelf (COTS) or under development for the commercial market, partially meet the STIDs criteria, but have been designed and built for specific systems and hence are loaded with hardware irrelevant to the functionality of the STIDs. For those display technologies to be adapted for the STIDs, they have to be stripped from excess components and trinkets, redesigned and rebuilt not only to reduce the cost, size and weight but also to simplify their architecture while maintaining the functionality of the human machine interface. Furthermore, repackaging may be necessary for ruggedness and reduction in cost and size, since commercial products are concerned with decorative appearance that appeals to the consumers and marketability often takes precedence over usability. Furthermore, ergonomics for devices designed and constructed for civilian use differ from the human factors that have to be implemented for the battlefield.
New display technologies such as organic light emitting diode (OLED) and electronic ink displays (EID) cost less in manufacturing and use material less expensive than that used in the more commonly available liquid crystal displays (LCD). OLED employs polymers or organic molecule substrates that can be made of agricultural products. EID employs paper substrates. OLED consumes much less power than LCD, while EID power requirements are a fraction of that required for OLED. Nevertheless, both OLED and EID technologies have yet to develop to the level of maturity and market penetration of the LCD technology. Although the EID technology seems to satisfy the STIDs criteria the most, its development seems to lag behind the OLED technology. Both technologies suffer from the drawback of having short useful life, although this might not be a major impediment for building throwaway displays like the STIDs.
Batteries that are standard for commercial displays cannot deliver the necessary juice for continuous operation during a typical mission without frequent replacement. All COTS batteries of reasonable weight (e.g., suitable for a wrist or head-mounted application) fall short of lasting the required 6 hours. In addition, long life is not the only factor to be considered in selecting rechargeable batteries; as important is the reliability and availability of the power source when needed. Batteries, being dependent in operation on chemical reactions, tend to have uncertain life expectancy and may fail to function when needed the most. That is, their availability when needed as a power source is rather low. Rechargeable batteries often deteriorate in performance and last fewer hours after repeated charges.
One solution to such shortcomings is to direct attention to batteries being used in space; some of which, such as nickel-cadmium batteries last over 10 years. Batteries used in pacemakers produce less energy but are also extremely reliable. Nuclear (beta-emitters or radioisotope) batteries are possibly the best candidate for STIDs because of their high operation life, reliability and dependability. They use a mature technology that has been tested and improved over the years, and can be customized for every application. An evidence for the safety and dependability of the nuclear batteries is their use in pacemakers early on. Although space-grade and nuclear batteries are costly, the trade off in this case is the ability to use the batteries over and over in successive generations of displays. Fuel cells are another promising alternative to traditional batteries, but the technology is still very immature.
Improvement on materials, development of new materials and use of polymers made it possible for some displays to survive exposure to temperature extremes in the range of -20º to +70º C for extended periods. Although the state-of-the-art technology can produce LCD displays that survive and correctly operate after being submersed at depths of 2 atmospheres for 3 hours, parachuted from altitudes of up to 20,000 feet, transported by air at altitudes up to 40,000 feet, this will be at an added cost premium regardless of the display technology. Since environmental compliance is a constraint on the construction of the STIDs, means to further reduce the cost are necessary to implement in order to offset the increased costs of survivability.
We have constructed a Phase I prototype which illustrates the technical feasibility of wireless displays meeting the SBIR requirements. The prototype is a handheld unit, constructed primarily from off-the-shelf components, incorporating a 6.3" Toshiba LCD display, wireless networking components, an on-board computer for handling decompression of the video stream from the source display, and onboard NiMh batteries. A 4" Toshiba LCD was originally planned, but significant backorders (> 12 weeks) precluded our obtaining one in time for the end of Phase I. On the software side, we have adapted VNC and Tight-VNC software to capture changes in the source display and handle compression/decompression of transmitted video. Our prototype uses Bluetooth or 802.11b wireless networking and while we do not currently constrain transmission power to prevent detection beyond 50 feet, modifications to our software can be made to achieve this in Phase II. Additionally, even when detectability is reduced, other threats to wireless communications are and will continue to be major issues of concern that affect acceptability of STIDs. Our software can easily accommodate encryption of the video stream to further harden the wireless STIDs against tampering and eavesdropping. One positive deviation from the original SBIR specification is that we require no hardware to be attached to the computer providing the source display—it need only run a small software application.
The Phase I prototype is a proof of concept, and several enhancements will be necessary to move the STID designs forward in Phase II. We have created baseline Phase II designs for wrist-mounted, handheld, and head-mounted wireless displays which address further reductions in size, improved refresh rates, alternate wireless networking technologies, and better power management. Better refresh rates will be gained primarily by incorporating a more powerful on-board computer and by continuing to enhance our software. Surprisingly, we do not believe our designs are bandwidth starved—additional wireless networking bandwidth will offer only incremental improvements in refresh rate. For Phase II, the wireless transmitter will be packaged into a small box to be attached to an LCD or OLED display element. We will strive to separate the wireless networking and software issues from the choice of display elements to the highest degree possible, allowing a number of display types to be tested easily. For example, since at least two displays of each type (wrist-mounted, head-mounted, etc.) are required in Phase II, one LCD and one OLED display of each type might be constructed. This separation of networking issues and display technology has the added advantage of allowing our designs to rapidly embrace emerging display technologies. As for the Phase I prototype, only a wireless networking interface is needed on the source computer—no hardware is required to be attached to the source. Extensive user acceptance testing will be conducted in Phase II to demonstrate environmental compliance and successful performance of desired functions. Feedback from these tests will be used to improve the STID designs.

Our software can easily accommodate encryption of the video stream to further harden the wireless STIDs against tampering and eavesdropping. One positive deviation from the original SBIR specification is that we require no hardware to be attached to the computer providing the source display—it need only run a small software application.
The Phase I prototype is a proof of concept, and several enhancements will be necessary to move the STID designs forward in Phase II. We have created baseline Phase II designs for wrist-mounted, handheld, and head-mounted wireless displays which address further reductions in size, improved refresh rates, alternate wireless networking technologies, and better power management. Better refresh rates will be gained primarily by incorporating a more powerful on-board computer and by continuing to enhance our software. Surprisingly, we do not believe our designs are bandwidth starved—additional wireless networking bandwidth will offer only incremental improvements in refresh rate. For Phase II, the wireless transmitter will be packaged into a small box to be attached to an LCD or OLED display element. We will strive to separate the wireless networking and software issues from the choice of display elements to the highest degree possible, allowing a number of display types to be tested easily. For example, since at least two displays of each type (wrist-mounted, head-mounted, etc.) are required in Phase II, one LCD and one OLED display of each type might be constructed. This separation of networking issues and display technology has the added advantage of allowing our designs to rapidly embrace emerging display technologies. As for the Phase I prototype, only a wireless networking interface is needed on the source computer—no hardware is required to be attached to the source. Extensive user acceptance testing will be conducted in Phase II to demonstrate environmental compliance and successful performance of desired functions. Feedback from these tests will be used to improve the STID designs.

SUMMARY
Aiming at development of voice input and output mechanisms and devices to assist individuals with handicaps (IWH) has resulted in the conceptualization of a computer-based learning aid characterized by being user-friendly, interactive and efficacious. Accessibility of IWH to the benefits of voice input and voice output devices, especially in microcomputers, has been limited by incompatibility with their needs and high cost. Thus, a voice interactive learning aid for individuals with handicaps (VILAH) was designed as an affordable, computer-assisted instruction system that allows for individualized teaching programs with minimum dependence on tutors. Advances in speech technology and the associated computer support have the promise of resolving ambiguities in recognition and enhancing the overall capability.
Progress in speech recognition and synthesis has been nurtured by the keen interest of the industry and the National Defense in automation, control and robotics. The sophistication level of the technology needed in those applications has limited the implementation of proven and yet novel techniques. Thus, an effort was expended in assessment of technology to identify means to improve voice input and voice output systems for IWH considering the modest needs for a learning aid. Though the VILAH concept has been envisioned as a simple system that utilizes artificial intelligence (AI) as an enhancement tool, the latest achievements in technology have assisted in definition of a set of specific requirements. Those were used to design a skeletal structure of the system to a level of details sufficient for implementations including the engineering and system design, testing, codification and programming, and demonstration.
Regarding speech synthesis, an allophone library provides a permanent source of natural languages. An effort was also made to refine the computer spoken language in order to provide a high level of intelligibility. Regarding the speech recognition, conventional systems are retrofitted to reach a reliability of at least 99%, by introducing an innovative neural coprocessor. An inference engine is employed in the speech recognition module as well as in the application algorithms to facilitate programming. Also efforts have been made to filter noise and obtain representative signatures of spoken words.
The VILAH design uses off-the-shelf, inexpensive components and is based on proven technology. Technical feasibility has been shown and benefits of the learning aid much exceeds the costs. Commercial viability is assured since a voice interactive system is in demand for a wide range of applications, in addition to the primary benefit to individuals with disabilities. The advantages of computerized voice output from printed material for blind or visually impaired individuals is obvious. Very often individuals with language-learning disabilities fall into this category. The advantage of synthesized speech is obvious for individuals who, for a variety of reasons, cannot speak themselves. The advantages of being able to speak to and listen to the teaching source is also obvious for very young children, with or without handicaps, who can neither read nor write. Furthermore, persons who have moderate to severe mental retardation are, by definition, normally unable to read or write. Therefore, the typical printed screen or print-out mode or the keyboard typing input mode are, for all practical purposes, inaccessible for them. Other individuals who cannot easily utilize the typing input mode are those with physical handicaps. The purpose of the project was to develop a voice-interactive learning aid for individuals with handicaps (VILAH), specifically, voice-interactive computer-aided reading instruction (VI-CAI). To accomplish this a team of professionals with educational and programming expertise from Technology International Incorporated (TII) collaborated to modify existing off-the-shelf speech recognition/synthesis systems to improve the quality of speech output/ input so that it could be used by students with handicaps. The VILAH team developed VI-CAI reading software designed to improve reading comprehension, ensure high success rates, and motivate students to read for learning and fun.
Two prototypes were demonstrated to special educators, engineers, and others interested in VI-CAI for individuals with handicaps to get initial feedback from knowledgeable experts. They were also demonstrated to potential economic developers to explore funding sources for Phase III, the production phase of hardware/ software prototypes developed through the present funding. Modified and unmodified versions of the off-the-shelf speech synthesis/recognition systems were tested with students with handicaps, specifically learning disabilities (LD) and mild/moderate mental retardation (MR), to determine whether the speech synthesis/recognition modifications were effective. Modified versions were better on all measurements.
Finally, students with LD or MR classifications were assigned to experimental and control groups to determine whether those receiving the developed VI-CAI made greater reading comprehension gains than matched students receiving traditional classroom instruction. These demonstrations indicated that participating in the VI-CAI reading program improved reading comprehension gain scores over a matched control group.

SUMMARY
The logic of an interactive set of five databases is designed and partially implemented on an expert shell to enhance job development, job modification, job opportunities, or transition from school to work for individuals with disabilities. The expert system provides the optimal match between capabilities of individual with severe disability, available job performance requirements, and robotic job aids based on economic viability in terms of salary earned, amortized costs, payback, subsidies and net gains or losses. The system is described in detail including the constituents of each database, methodology for construction and continual updating of information, and its feasibility in providing assistance for adaptation of competitive jobs in particular service industries for performance by individuals or a team of individuals with severe disabilities to perform within a normal work setting.
The databases provide information to five modules:
Initial sources of information for Databases I, II and IV were determined through an extensive survey of public and private rehabilitation organizations and companies serving the insurance industry as well as a number of insurance companies. The construction Databases I and II requires the development of standardized tests and measures to determine computer and teleoperator interfacing capabilities of individuals with disabilities.
The concept of a Test Center is recommended so that employers contemplating the use of robotic job aids can experiment directly or by simulation with the requirements and thereby determine the engineering and economic feasibility of using a given robotic job aid system in a particular application without having to purchase the system. The benefits of the system outweigh the costs of training or other assistance programs. A major benefit is the ability of the individual to access relevant information to allow selection of career path and to assure success of the use of robotic aids. The expert robotic job aid information system will also benefit individuals with disabilities seeking employment, employers wishing to employ them, and the developers and marketers of robotic equipment by targeting limitations, needs, opportunities and capabilities on specific applications. It is estimated that a robotic job aid information system will pay for the cost of its development and operation many times over in reducing the need for prolonged disability compensation, in stimulating the development of robotic and computer interfacing technology and in providing new insights into understanding the human/computer interface.

SUMMARY
The first phase of the program was directed at the development and estimation of the feasibility of a Job Aid Expert system (JobAid Expert). JobAid Expert is conceptualized as a computer-based system that enhances the chances of gainful employments of individuals or a group of individuals with disabilities by matching individuals to jobs and job aids or robotic job aids. The job aids would facilitate the performance of a given job to provide high performance in a competitive job environment. Advances in job aiding devices, workstation interface systems, automation, and robotics provide new tools that would allow an individual with disabilities to compete in the normal setting of a variety of jobs. Special considerations were given to the service industry and to types of disabilities that impair the motion, rather than vision and speech impairments. Also, emphases were placed on transition of students with disabilities from school to the job marketplace. Extension of the concept to other types of job opportunities and types of disabilities is possible.
The JobAid Expert utilizes expert shells, databases, and knowledge bases. By providing matching rules in the expert shell, the information and data stored in the databases and knowledge bases will be accessed simultaneously to provide an optimal match. Information required for implementation was acquired including types of disabilities and associated speech, mental and motion capabilities as well as the potential of acquiring special skills such as mechanical computer skills. Also, information on the capabilities required to perform specific tasks in various jobs were compiled. To assist the individual, commercially available robotic and job aids were examined to identify possible adaptation to facilitate task performance. In case of lack of an aid, the requirements for development of such aid were evaluated. Decisions have to be based on the cost versus benefit to assess the viability of using the aiding devices.
A prototype system (JAExpert) was constructed using PC-Expert Professional shell and C language. The system utilized a menu-driven user-friendly architecture on a personal computer. Simple commands were used for ease of operation and demonstration. An alpha test of the prototype was performed and showed the feasibility of the concept.
Extension of the prototype to a full scope system to be used by counselors, habilitation organizations, job services, job aid manufacturers, and individuals with disabilities requires a more powerful expert shell which can interact with various databases and other programs. The use of the Mentor expert shell was recommended as a tool that can provide the required services. Also, means of communications with a central system were recommended.

SUMMARY
Technology International Incorporated of Virginia (TII) has developed a prototype “ASL Math Tutor,” an illustrated, interactive multimedia framework which incorporates children’s stories and math lessons in both English and American Sign Language (ASL) for the promotion of math skills of deaf and hard-of -hearing children at the elementary school level. The effort targeted grades K through 6 yet it is still useful for higher grades. The framework provides a means of expressing, teaching, and learning math terms and concepts in ASL as well as in English. The distinguishing features of the math instruction presentation are the video clips of ASL and the colorful, exciting graphics that define and illustrate the math concepts and present the terms on a computer screen. The written English definitions and voiced interpretation of the scientific terms are coordinated with the ASL video and illustrations. For deaf and hard-of -hearing children, video presentation, rich illustrations, and the ASL representation of math concepts will increase the acquisition and enhance the technical development of the targeted children.
Placing the instruction on a CD-ROM makes the academic content easily accessible via personal computers to the targeted audience as well as the deaf and hearing community at large. These combined features provide a complete, multifaceted educational tool, which may be applied to a variety of purposes and populations. For example, deaf, hard-of-hearing and hearing students can increase their knowledge of math, English and ASL. Teachers of the deaf and the hard-of-hearing can use the CD-ROM as a classroom math teaching tool and as an ASL resource. Parents and hearing adults in general could monitor their children’s progress in the area of math and gain knowledge of ASL.
The ASL Math Tutor math lessons are initially developed for CD-ROM format. This format has a direct market for the home PC of families of deaf and hard-of -hearing children. It also has a direct market in the realm of education of deaf and hard-of -hearing students at the elementary school level and eventually middle and high school. Classrooms and libraries in boarding and day schools for the Deaf, as well as public schools that mainstream children with hearing losses have a clear need for educational tools that are designed specifically for this population. Placing the math instruction capability on the World Wide Web will provide greater benefits to the deaf and hard-of -hearing students, their tutors and families.

SUMMARY
This Small Business Innovation Research (SBIR) Project addresses the development of a computer-based multimedia system that utilizes computer, video, and electronic graphic systems to present visual translations of audio inputs from music. The overall effort involves conceptualization, development, design, prototyping, evaluation, and implementation of Graphic User Interface (GUI) and software programs that provides deaf people full access to the joy of music through production of a set of visual music CD-ROM’s. The ultimate goal of the proposed program is to provide the visual software and hardware tools for production of CD-ROM’s that present music to the deaf and hard of hearing in a manner that can convey all elements of music appreciation; rhythm, melody and harmony, and convey the poetic essence of the words and their sound quality through signing. The tools will be designed for use in providing training on music appreciation by the deaf and hard of hearing students.
In Phase I the development is aimed at proof-of-concept prototyping of a combination of audio, visual presentation of selected simple, and popular music themes and songs on a CD ROM for use by deaf persons from all age groups for music learning, appreciation, recreation, and leisure time activities. The graphics representation involves a variety of waveforms with dynamic changes of color intensity. This is in addition to the use of ASL video clips for interpretation of lyrics and the music in a manner that provides appreciation of the melody and harmony as well as the rhythm and conveys the variations of instrumentation. Accessibility of the capability on the World Wide Web is studied. A music performer is also introduced to work with the display systems to create music through a MIDI musical board.
The outcome of the project includes tools for music translation for training and production of CD ROM sets of visually based music and songs, and capability to translate audio inputs to visuals on the World Wide Web, for use by deaf individuals in visual display of music combined with awareness of sound effects. The products will have high commercialization potential in clubs, libraries and schools of the deaf as well as deaf individuals.

SUMMARY
Phase I of this Small Business Innovation Research (SBIR) Project addresses the development of an innovative, interactive, web-based “Adult Learning Interactive Multimedia” (ALIM) capability to facilitate assessment and teaching of higher-order reading and comprehension skills to adult learners who have less than a high school diploma. Development of ALIM will involve adaptation of emerging and cutting-edge technologies for improving teaching and learning; including the most recent multimedia authoring, presentation, web, storage, and delivery tools that permit interaction on the web between the teacher and the learner and provide the learner with feedback on queries or response to questions. The software is developed in HTML however it is conceptualized to operate in a Java-based environment.
The ALIM prototype consists of a user-friendly computer-based instructional technology system, wherein instructors can use interactive, multimedia course modules on the Internet to provide the material necessary to enhance adult reading and comprehension skills. Illustrations, representation of concepts and interactive exercises, a vocabulary level checker/thesaurus, and a web mail are also included. Access to the system allows the learner to use the system at his/her pace with maintenance of a large degree of privacy, interactively review the information of interest and communicate with instructors by web-mail.
Being web-based; adult learners are encouraged by anonymity to use ALIM. Outcomes of the use of the ALIM-course modules are expected to include literacy, compuracy and fluency. Extension of the ALIM for enhancement of numeracy and language proficiency is natural. ALIM can also be used to develop instructional materials for adults with learning disability.

SUMMARY
The results of Phase I included an effort to develop and implement a novel technique for on-line early detection of degradation and wear in LMFBR equipment. The approach evolves around design of a wearout monitor (WONITOR) as a diagnostic tool capable of providing the operator with indication of early symptoms of aging of specific equipments during operation. Phase I is concerned about evaluation of the feasibility of and identification of the requirements for the development of the WONITOR.
The WONITOR has to be designed for specific equipments. Hence, candidate equipments for demonstration of the capability of WONITOR are selected. LMFBR equipments for which early detection of wear is critical have been identified, using EBR II as a specific case. The selected equipments are then rank ordered; using value-impact analysis, according to the impact of their performance on LMFBR safety and productivity. The intermediate heat exchanger and the primary centrifugal pumps top ranked other primary equipments.
The WONITOR is based on adaptation of parameter identification techniques using regression models to analyze fluctuation data from measurements of parameters related to the equipments of interest. Such parameters are identified as flow rate measurements, temperatures, and pressure. Considering the case of EBR II, fluctuation data from such measurements are evaluated and found adequate for providing information on the state of the selected equipment. No additional instrumentation or sensors seemed to be necessary for the information required for implementation of the WONITOR. Ultrasonic techniques and in-service visual inspection are explored as means of localization of wear following its detection. A combination of both methods is conceptualized.
Specifications of the WONITOR are detailed including software logic, hardware, ancillary equipments, and layout of the system in the plant proper. Implementation cost estimates are found in the neighborhood of $360,000 in 1985 dollars. The present development of the WONITOR indicates that the system can be easily applied to other equipment in LMFBRs. The system can be directly adopted for light water reactors. Also, the wear monitor is suitable for wear detection of equipment operating in hostile environments or in operation environments inaccessible to human.
The objective of the Phase II work was to design a wearout monitor for on-line diagnostic surveillance. The approach is to utilize operation data to identify measures associated with aging of specific equipment, then, to monitor these wear measures through the use of updated operation signal data. Results include: theoretical equipment modeling for intermediate heat exchanger and pump, sensitivity analysis, operation and simulation data analysis, signal characteristic determination and correlation analysis. Identification of wear related parameters and development of wear measure parameters for monitoring purposes for selected IHX and pump wear scenarios. The software modules are integrated into a user-friendly menu-driven wear monitor system called WONITOR. The project results provided a system for early detection of wear in nuclear power plant equipment which would assist in plant maintenance and operation. Minor modifications can be employed to adapt the monitoring system to other processes.
Patent Abstract
A wearout monitor for failure prognostics is a prognosis tool to predict incipient failure in rotating mechanical equipment. The wearout monitor provides maintenance management of a plant or process with information essential to planning preventive maintenance strategies. The monitor also assists in constructing a data base for development and implementation of policies for plant life extension, refurbishment, and modernization. The apparatus identifies systems of operation degradation of the whole system, as well as diagnosis of signs of commencing aging cycles of specific equipment, components or parts of equipment during operation. Data from the system is stored and also supplied to a central processing unit which includes an expert system, rule-based failure data bank, a predictor, a performance evaluator and a system identifier. The results of the predictions are supplied to management terminals or other indicators for subsequent use. Combination of prognostics and diagnostics of the symptoms of existing fault in mechanical equipment allows continuous on-line monitoring of systems to predict failures at early stages before leading to catastrophic breakdown and to assure safe and economic operation. By providing correlations between defect sizes and life expectancy of a rotating mechanical component, the monitor can provide the operator of the equipment with a warning time that indicates the time before loss of operation, thereby being critical to operation of transport systems wherein gearboxes can lead to loss of transmission power and subsequent loss of life particularly in helicopters.

SUMMARY
Present in-situ low-level liquid radioactive waste processing techniques involve the production of secondary streams; such as spent resins and evaporator bottoms. Processing temperatures also contribute to the gaseous streams. To minimize the secondary streams waste, the innovative system; examined in here, can be employed as a retrofit or as a replacement of existing liquid waste streams. The electrodialysis and freezing processes do not add to the waste burden. In addition, high concentration (high recovery) of the radioactive elements (pure water) lead to a high volume reduction of the waste from the plant. The processes can also handle volatile elements to reduce the gas waste.
The arrangement of the freezing and ED units is also considered. For this specific stream a freezing process followed by ED treatment is preferred. However, this arrangement has to be verified experimentally.
A prototype system (JAExpert) was constructed using PC-Expert Professional shell and C language. The system utilized a menu-driven user-friendly architecture on a personal computer. Simple commands were used for ease of operation and demonstration. An alpha test of the prototype was performed and showed the feasibility of the concept.
The new system is appropriate for processing low purity waste (high conductivity) streams and chemical waste streams. A freezing unit can be used to treat the high purity (low conductivity) waste streams. However, conventional methods will also suffice. A freezing unit may also be used to process laundry and floor drain wastes whenever needed. The new system is appropriate for boiling water reactors (BWRs) for all streams of liquid waste. The system is expected to meet utility requirements. Also, the system can operate well within regulatory limits. Detailed plans are made for a pilot experiment. The cost of the experiment is expected to be in the $500,000 range.
Patent Abstract
A volume reduction process comprises combinations of a freezing eutectic, bulk, indirect crystallization process and a radwaste electrodialysis process. When employed as a liquid radioactive waste management system (LWMS) for light water reactors (LWR's), this process is designed to process liquid low-level radioactive waste (LLW) and to handle the radioactive influent in nuclear power plants (NPPs) prior to release to the environment and disposal of the radioactive material present in the waste streams.

Application of fuzzy set theory to automatic control has shown to affect high quality reliable controls in applications pertinent to nuclear power plant equipment. A scheme is developed her based upon incorporation of software-tolerant method to assure high reliability of software. Application of the method to centrifugal pumps and heat exchanger are selected to demonstrate the viability of a redundant technique utilizing fuzzy and deterministic controls. The work is aimed at development of a methodology to assure reliability of control systems when they interact or become part of the plant protection system. This is a step towards providing autonomy in controlling complex processes; such as nuclear reactors.
The work in Phase I of a project to Design a Reliable Fuzzy Fault-Tolerant Automatic Controller (REFFTAC) is reported here. The REFFTAC is based on the employment of two diverse controllers. Reliability is achieved via redundancy and diversification in the design. Control actions are tested via an interface between the two controllers. The interface system assures error-free control command, delegates the control action to either controller, and actuates a tie-breaker in case of a disagreement between the two controllers.
Though the logic design of the REFFTAC is developed for a generic process, the controller is designed for a heat exchanger and its applicability to a pump is examined. The fact that most power processes involve a boiler or a heat exchanger and pumps led to that selection. However, the designed controller can provide continuous and discrete control actions to other processes.
In the design of the REFFTAC logic, a primary adaptive direct digital controller was designed based on parameter estimation and on-line control design. The output of the adaptive controller is examined to assure proper control actions and to transfer the control command to a fuzzy controller in case of failure. The fuzzy controller provides heuristic control actions based on predetermined strategies.
The reliability of the REFFTAC is examined using complexity analysis, and failure mode and effect analysis. A high level of fault-tolerance is expected to be achieved by deployment of this controller. However, a reliability criterion is employed in which the controller would be able to perform control tasks as good as a human operator. To enhance the reliability of the system, a self-diagnosis scheme is provided. Also, both controllers employ a learning expert system that utilizes historic data in control design.
As a follow-on of this work, the reliability needs to be tested in the environment of fault-tolerant hardware. The plan is to demonstrate the REFFTAC on a full-scope simulator and on EBR-II as a test facility. This is to examine the operability of the controller as well as it superiority over redundant or single controller. Higher targets of reliability also needs to be tested.
The REFFTAC utilizes proven technology and is found to be viable in control of heat exchangers and pumps. The fact that the system can be customized for various operations allows for application in complex processes which can be automated.
The fuzzy controller has the merits of being able to adapt operating procedures as control functions without the need for elaborate modeling, of using technical specifications as limits of operations, and of designing controls based on past experience.

SUMMARY
A prototype Voice-Assisted Data Entry (VADEÔ) system has been developed for processing Medicare and Medicaid claims, to increase the efficiency of management and general operation and to facilitate entry of patient data associated with tasks required of health agencies. The VADEÔ system was designed to incorporate all the standard information content associated with the existing claims for filling out of the forms through voice recognition technology while allowing for voice-assisted processing of modified or new claim forms as well as performance of associated management functions. Accordingly, the VADEÔ package reduces the burden of data entry, eliminates the need for extensive visual search and manual cross referencing of code manuals, enhance the overall efficiency of the process, and increases the productivity of the personnel involved. Technology International Incorporated of Virginia (TII) developed the graphical user interface (GUI); incorporated diagnosis codes, medications, and patient data into databases to allow for instantaneous cross-referencing of claim information; and employed a speaker-independent speech recognition system along with customized software developed in Visual Basic to allow voice input of form data and automatic input of diagnosis and claim codes based on the verbal descriptions given.
Follow on efforts are aimed at the full development and demonstration of the hardware/ software of the VADEÔ system for the completion of medical digitized forms via automatic speech recognition. The objectives involve beta testing with home health agencies, and expansion of the VADEÔ system to a networked, multi-platform environment to allow implementation over local area networks, company Intranets, or over the World Wide Web.

SUMMARY
To meet the needs of the Federal Railroad Administration (FRA) safety program for an innovative advance in the design of an alerter system to be used in locomotive cabs, Technology International Incorporated (TII) developed and evaluated several concepts for an advanced, reliable locomotive cab alerter (CabAlerter), including:
Follow on efforts are aimed at the full development and demonstration of the hardware/ software of the VADEÔ system for the completion of medical digitized forms via automatic speech recognition. The objectives involve beta testing with home health agencies, and expansion of the VADEÔ system to a networked, multi-platform environment to allow implementation over local area networks, company Intranets, or over the World Wide Web.
Railroads have employed many devices to warn the locomotive engineer of impending danger. These include fuses, torpedoes, flags, lights, fires, the deadman switch, and radio communication (where available). The key issue of all devices is to maintain the level of conscious alertness of the engineer. Modern alerter systems produce a light signal prompt at regular intervals if an engineer's action does not otherwise reset a timer before the end of the selected time interval. The engineer's response involves touching, and in most cases operating a control (such as the throttle) on the operator's console or pressing the alerter reset switch. If the appropriate reset action is not taken in a specified period of time, an audible alarm will sound. The same actions that reset the light prompt will reset the audible alarm. If response is not made to the alarm within a specified period of time, the train brakes are automatically applied and the train is stopped. It is now believed that an experienced engineer can and may reset the alerter timer when the light prompt appears (before the audible alarm) while actually dozing or asleep and thereby defeat the purpose of the alerter system.
Information available on environmental work stress in the locomotive cab was analyzed. An interview was held with an engineer from the Illinois Central Railroad with over 30 years of experience in the Baton Rouge district. He confirmed observations made earlier and offered additional insights based on personal experience, including:
Three basic strategies were examined for maintaining alertness in the locomotive cab:
Studies of locomotive operation were conducted to provide the basis for simulating train operation in the laboratory, which was needed for full scale laboratory testing and evaluation of the DigiAlerter and other cab alerter systems. Information on locomotive operation was gathered from visits to locomotive cabs and a study of cab operating systems, accompanied by a locomotive engineer; discussions with locomotive engineers; and studies of several manuals of operating rules and instructions for train operation.
The locomotive cab presents severe restrictions in the location and size of a cab alerting device. Considering the geometry and layout of the cab and of the engineer's workstation, it is feasible to locate the cab alerting system somewhere on the throttle stand. Several locations could be used; however, it is necessary that the alerting device be small, no more than five to six inches on a side and no more than two to three inches deep so that it does not protrude into the work area. Any device placed in a locomotive cab has to be protected from vibration, dust, moisture, temperature extremes, and occasional impacts. Simplicity and ruggedness are necessary for a device to perform reliably with a minimum of maintenance over time under these conditions.
Design requirements and feasibility criteria were established indicating that the device has to be:
Using these design and functional requirements and feasibility criteria, several concepts were screened and rank ordered according to the degree of meeting the criteria. Trade-offs was made between the DigiAlerter and other systems (MovAlerter, KeyAJerter, DynAlerter) on a conceptual basis. A Locomotive Cab Alerter Simulator (LCAS) was developed for evaluation of the concepts and for comparison of design options. Trade-offs were made using the DigiAlerter as the baseline design. Other trade-offs were considered regarding the frequency of alertness testing and actions to be taken when no response is given in the alarm mode of a two level response task. Trade-offs involving the type of response required in the alertness monitoring test, including the length and type of display (letters versus numbers) were evaluated experimentally. Additional trade-offs were made during simulated locomotive operation tests to finalize the design of the DigiAlerter as an alertness monitoring device.
TII has selected DigiAlerter as a viable CabAlerter that meets the FRA requirements and meets all the feasibility criteria. The DigiAlerter was designed, constructed, and bench-tested as a Proof-of-Concept (POC) CabAlerter for prototyping and field demonstration. The CabAlerter system is intended to ensure that the locomotive engineer remains alert to operating restrictions or otherwise stops the train if the engineer does not respond properly to provide prompts. This low-cost innovation can be retrofitted to alerter systems already in service.
A full scale software model was implemented on a 486 microprocessor to emulate the actual "look and feel" of the DigiAlerter from a visual and functional perspective. The program allows an evaluation of the system and the user responses through parameters such as length of the alphanumeric string, allowable response time before an alert mode is entered, number of times the user must correctly respond to codes in the alarm mode before the simulation resumes normal operation, probability of a letter occurring in the code, and minimum and maximum bounds on the delay between new codes.
The POC hardware design of the DigiAlerter consisted of a sixteen-key keypad with an attached four character Light Emitting Diode (LED) display. Upon starting the prototype DigiAlerter, it generates four random characters in the range 0 to 9 or A through F. These characters are then displayed on the LED readout. The user must enter the code though the keypad. If he/she enters the code correctly, the system will delay approximately one to two minutes and then display another four-digit code. If the user enters the code incorrectly, the system will switch to an alarm state. Once in the alarm state, the system will not generate additional codes until the reset button is pressed. Two LED's, one red (alert mode) and one green (normal mode), were provided for indication of the state of the DigiAlerter. As long as correct codes are entered, the green LED will remain lit. If an incorrect character is entered, however, the red LED will turn on.
Several preliminary tests were performed, including an alert testing computer simulation using keypads, the DigiAlerter emulator on the microprocessor, and the POC hardware.
A standard keypad entry device was interfaced with a PC using specially written software to produce a LCAS similar in operation to the TII DigiAlerter. The LCAS generates random codes of selected length and type (numeric, alphanumeric, or letters only) at random intervals on a screen to the user (representing the locomotive engineer) whose task is to repeat the code by entering it on a keypad in order to reset a timer which will then delay for a randomly chosen interval. At the end of this interval the process is repeated. If the user fails to enter the code within a specified time or if he/she enters an incorrect character, the system switches into an alarm mode. When this happens, the user must enter another randomly selected code correctly using the keypad a specified number of times within a specified time period in order to cancel the alarm mode. If the user fails to complete the required sequences in the alarm mode, the alarm will be activated. The program written for this experiment specified that the train would automatically be stopped (as when the braking system is put into emergency mode when the conductor activates the emergency brake).
A series of controlled laboratory experiments were conducted, using LCAS. The experiments involved four independently tested male subjects aged 22-26 years to investigate the concepts and alertness criteria and to determine the optimum characteristics of the response required to verify alertness. Since the job of operating a locomotive is variable in its cognitive demands and does not require a fixed posture or eye focal point, the task used to simulate this job consisted of engaging the subject in a group conversation with three other male participants while also providing background music. Other normal computer related activity (conversation, printing laboratory reports, etc.) was present in the surrounding area.
It was determined experimentally that a recommended alertness test protocol, consisting of a visually presented six-letter string, be keyed in using a standard alphanumeric keypad, possibly with an audio or visual signal indicating that the test is being made. Failure to respond correctly or within 13.35 seconds would result in the activation of a signaled alarm mode requiring the correct entry of two additional six-letter codes. Failure to perform this second level task would result in intervention or a stream of cool air being blown into the engineer's face, possibly from several angles. It was estimated that the alertness test should be given every 10-30 minutes during long runs across sparsely populated areas.
The software emulation test was carried out simultaneously with hardware design. After a random delay, the program displays a variable length code consisting of letters and numbers. The user then has a fixed amount of time to respond by selecting the correct digits from the simulated keypad using the mouse. If the user enters the code correctly within the specified time limit, the program waits a random amount of time before displaying a new code. If the user enters the code incorrectly or takes too much time to respond, the program enters the alert mode. The user must in this case correctly respond to a user-specified number of random codes to prevent the system from setting off a simulated alarm (a buzzer). If the correct code is entered each time, the program will return to normal operation, waiting a random amount of time before displaying a new code. If the user fails to enter in each code correctly, the program will inform the user that an error has occurred. Following each session, the program records the results of the simulation to a file. These results include: the user's identification number, the length of the generated codes, the probability of occurrence of letters, the correct character and missed character (in the case of a failure), the time the user required to respond to each code, and a result code. The data file is particularly useful in determining the optimum parameters for the final hardware implementation of the DigiAlerter.
The POC hardware model was tested for operability and functionality. Considering the attributes of a viable CabAlerter, the POC tests and the construction and operability tests of the POC model of the DigiAlerter have shown that the selected alerter is technically feasible and commercially viable.
The feasibility evaluation shows that:
Based on the POC model, the results of the tests, and the feasibility estimates, a prototype alerter was designed for implementation in Phase II. Also, plans are provided for Phase II, which will involve demonstration of the alerter in an actual moving environment. The DigiAlerter prototype planned for Phase II must perform the following functions:
The concept for stimulation of the engineer has been established, options include cool air stream, scented mist, etc. Actuation signals are available in the POC model. Phase II will incorporate the appropriate refreshing system and the interfaces with other cab equipment and devices. In addition, Environmental Qualification (EQ) must be performed. This requires consideration of the operability of the DigiAlerter in the locomotive cab environment as well as the ability of the engineer to smoothly interact with the device. The prototype design and construction in Phase II will accommodate for EQ factors in selection of the type and resolution of the display as well as the surface of the keypad (protected buttons versus membrane switch touchpad).

SUMMARY
To meet the needs of the Federal Railroad Administration (FRA) safety program for an innovative advance in the design of an alerter system to be used in locomotive cabs, Technology International Incorporated (TII) developed and evaluated several concepts for an advanced, reliable locomotive cab alerter (CabAlerter), including:
Follow on efforts are aimed at the full development and demonstration of the hardware/ software of the VADEÔ system for the completion of medical digitized forms via automatic speech recognition. The objectives involve beta testing with home health agencies, and expansion of the VADEÔ system to a networked, multi-platform environment to allow implementation over local area networks, company Intranets, or over the World Wide Web.
- A DigiAlerter based on a low-cost data entry device similar to a touchtone telephone keypad and to other handheld devices used for remote data entry. In its general form, the device is simply comprised of a keypad with a Liquid Crystal Display (LCD) window located on the top of a set of buttons or touchpad membrane. Each key is assigned a number or letter. A randomly programmed code formed of a string of characters to be entered is flashed on the LCD. Each number/letter or the whole code will flash for a short time and then disappear before the next number/letter is displayed. In the final model, the entire code will be displayed for a predetermined amount of time. By touching keys and entering a sequence of numbers or letters, a timer can be reset before the end of a selected time interval. The alphanumeric code will change each time the reset is required. Mental alertness is necessary to read the displayed code and simultaneously enter the code on the DigiAlerter pad. The random change of the code does not allow the engineer to systematically enter the code from memory without cognitive action.
- A KeyAlerter similar to devices suggested to prevent drunk drivers from starting the ignition of the car before being sober enough to drive, wherein the user resets a timer by turning a key after alignment with a beam of light. The KeyAlerter is the simplest of all concepts considered here.
- A MovAlerter design that involves touching a moving target (such as a bull's eye) on a touchscreen. The target moves in straight lines and bounces off the screen boundaries. The size and speed of the motion of the target can be adjusted within predetermined bounds. The engineer has to touch the touchscreen at the location of a moving target to affect a reset of the timer. The timer will only be reset by hitting the target on the touchscreen. Failure to hit the target the first time sets a localized alarm on the MovAlerter which is reset by subsequent success. Failure in the second round sets the actual alarm, which can only be reset by success of a third attempt. Success is awarded by an audible sound and a display on the screen. Failure is followed by a buzzer and actuation of alarms and eventual stopping of the train. The MovAlerter requires mental alertness to locate and touch the target on the MovAlerter screen. The target will appear at a random point on the screen and will require coordination and cognition to follow its path and score a hit.
- A dynamic PC-based DynAlerter similar to system simulators, which engage the operator in retraining as a secondary task whenever no primary tasks are required. This assures continuous alertness of the engineer at all times. The DynAlerter is viable provided that the engineer would not be overloaded to the extent of overlooking his/her task. The device has to be mounted in such a way that all annunciators will be in the Line-of-Sight (LOS) and road following functions can be performed. The central thrust of the DynAlerter lies in the collection and organization of valid, realistic operation and test items from actual railroad operations, together with an assemblage of the necessary hardware and software to administer the retraining and testing. The tests have to be stimulating and interesting to assure alertness. A system similar to the DynAlerter is successfully used by Electricite' de France (EDF) for operators of power plants. The integration of the DynAlerter in alert systems can be accomplished by introducing the timer or light prompts on the screen of the computer.
Railroads have employed many devices to warn the locomotive engineer of impending danger. These include fuses, torpedoes, flags, lights, fires, the deadman switch, and radio communication (where available). The key issue of all devices is to maintain the level of conscious alertness of the engineer. Modern alerter systems produce a light signal prompt at regular intervals if an engineer's action does not otherwise reset a timer before the end of the selected time interval.

If the appropriate reset action is not taken in a specified period of time, an audible alarm will sound. The same actions that reset the light prompt will reset the audible alarm. If response is not made to the alarm within a specified period of time, the train brakes are automatically applied and the train is stopped. It is now believed that an experienced engineer can and may reset the alerter timer when the light prompt appears (before the audible alarm) while actually dozing or asleep and thereby defeat the purpose of the alerter system.
Information available on environmental work stress in the locomotive cab was analyzed. An interview was held with an engineer from the Illinois Central Railroad with over 30 years of experience in the Baton Rouge district. He confirmed observations made earlier and offered additional insights based on personal experience, including:
- The deadman switch, which has been used on some locomotives, is impractical from the standpoint of postural fatigue and unreliable as an indicator of alertness.
- Work hours are long.
- Long and irregular hours of duty make it difficult to stay alert or even awake during monotonous periods, especially at night. Dozing off was a problem for a significant number of train crew personnel on some occasions.
- Wheel noise is more harmful to hearing than engine and horn noise.
- Climate control is lacking in the cab.
- There is a need for an alertness monitoring and/or alerting system of some kind. All control of cab crew alertness should be confined to the cab. Outside signaling or intervention is unnecessary, unwarranted, and unacceptable.
Three basic strategies were examined for maintaining alertness in the locomotive cab:
- Monitoring alertness by sampling and encouraging a self-alertness assurance strategy: This involves monitoring the alertness with two levels of testing and an alerting stimulus (alarm or cool air stream) to the engineer. This strategy is the one being pursued because it is the most practical, reliable, and acceptable approach.
- Maintenance of alertness through the introduction of secondary, possibly artificial tasks: While this strategy has theoretical merit based on laboratory research and application in other settings, it is not practical or acceptable to operators in this application. It is unrealistic to expect the engineer to perform tasks not related to his/her job just to prove alertness. These secondary tasks could also cause distraction from primary tasks in the event of unexpected emergencies.
- Having operating cab crew members maintain each other's alertness or take over each other's job functions: This is a type of "buddy" system that would require each of two or three crew members to monitor each other's alertness. Since crews often work together on the same schedule, all members could be fatigued at the same time. There would also be a tendency to cover for someone with a chronic alertness problem. Railroad job classification rules also forbid job substitution in the cab. Only a few conductors and brakeman are qualified to perform the duties of the locomotive engineer. The helper also cannot serve as a conductor.
Studies of locomotive operation were conducted to provide the basis for simulating train operation in the laboratory, which was needed for full scale laboratory testing and evaluation of the DigiAlerter and other cab alerter systems. Information on locomotive operation was gathered from visits to locomotive cabs and a study of cab operating systems, accompanied by a locomotive engineer; discussions with locomotive engineers; and studies of several manuals of operating rules and instructions for train operation.
The locomotive cab presents severe restrictions in the location and size of a cab alerting device. Considering the geometry and layout of the cab and of the engineer's workstation, it is feasible to locate the cab alerting system somewhere on the throttle stand. Several locations could be used; however, it is necessary that the alerting device be small, no more than five to six inches on a side and no more than two to three inches deep so that it does not protrude into the work area. Any device placed in a locomotive cab has to be protected from vibration, dust, moisture, temperature extremes, and occasional impacts. Simplicity and ruggedness are necessary for a device to perform reliably with a minimum of maintenance over time under these conditions.
Design requirements and feasibility criteria were established indicating that the device has to be:
- Physically sound, rugged, compact, portable, and tamper-proof.
- Compatible with existing equipment and alert systems: capable of interfacing with telecommunication systems, intervening equipment (e.g. braking system), and can be easily retrofitted in existing alert systems (e.g. audible or visual alarms).
- Compatible with cab layout and operation area: located within easy reach of the engineer while he/she is seated in a normal working position, visible under all operating conditions, and must not cover other displays or controls.
- Easy to operate operation causes minimum or no distraction from other operating tasks; operation should be stimulating, but not frustrating, boring, or routine; operation should involve manipulation and cognition tasks; errors can be recovered within a window of time; operation relies on randomness and changes after every use; operation is simple but not systematic and requires alertness.
- Functional, capable of indicating a level of alertness necessary for operating a locomotive, of providing cause-independent evaluation, and of establishing threshold for acceptable operation and processing time limitation; cannot be simply by-passed or rigged for self-response; has a built-in virtual award and penalty system, such as a pleasant tune as opposed to noise; provides feedback stimuli to the engineer's action; capable of interacting with intervening activity (to alert the engineer or stop the train) should this be necessary; easily programmable.
- Simple, reliable design: clear displays and controls, does not cause prolonged postural stress, poses minimal visual and cognitive demands.
- Compatible with cab operation environment: unaffected by severe weather extremes, thermal stresses, dust, fumes, odors, and withstands high levels of vibration.
- Cost-effective: low lifecycle cost, long service life.
- Acceptable by users: acceptable by locomotive engineers and other operating personnel as a device to assure their personal safety, not as a means for management to invade their personal work space or individual work behavior, acceptable to FRA.
Using these design and functional requirements and feasibility criteria, several concepts were screened and rank ordered according to the degree of meeting the criteria. Trade-offs was made between the DigiAlerter and other systems (MovAlerter, KeyAJerter, DynAlerter) on a conceptual basis. A Locomotive Cab Alerter Simulator (LCAS) was developed for evaluation of the concepts and for comparison of design options. Trade-offs were made using the DigiAlerter as the baseline design. Other trade-offs were considered regarding the frequency of alertness testing and actions to be taken when no response is given in the alarm mode of a two level response task. Trade-offs involving the type of response required in the alertness monitoring test, including the length and type of display (letters versus numbers) were evaluated experimentally. Additional trade-offs were made during simulated locomotive operation tests to finalize the design of the DigiAlerter as an alertness monitoring device.
TII has selected DigiAlerter as a viable CabAlerter that meets the FRA requirements and meets all the feasibility criteria. The DigiAlerter was designed, constructed, and bench-tested as a Proof-of-Concept (POC) CabAlerter for prototyping and field demonstration. The CabAlerter system is intended to ensure that the locomotive engineer remains alert to operating restrictions or otherwise stops the train if the engineer does not respond properly to provide prompts. This low-cost innovation can be retrofitted to alerter systems already in service.
A full scale software model was implemented on a 486 microprocessor to emulate the actual "look and feel" of the DigiAlerter from a visual and functional perspective. The program allows an evaluation of the system and the user responses through parameters such as length of the alphanumeric string, allowable response time before an alert mode is entered, number of times the user must correctly respond to codes in the alarm mode before the simulation resumes normal operation, probability of a letter occurring in the code, and minimum and maximum bounds on the delay between new codes.
The POC hardware design of the DigiAlerter consisted of a sixteen-key keypad with an attached four character Light Emitting Diode (LED) display. Upon starting the prototype DigiAlerter, it generates four random characters in the range 0 to 9 or A through F. These characters are then displayed on the LED readout. The user must enter the code though the keypad. If he/she enters the code correctly, the system will delay approximately one to two minutes and then display another four-digit code. If the user enters the code incorrectly, the system will switch to an alarm state. Once in the alarm state, the system will not generate additional codes until the reset button is pressed. Two LED's, one red (alert mode) and one green (normal mode), were provided for indication of the state of the DigiAlerter. As long as correct codes are entered, the green LED will remain lit. If an incorrect character is entered, however, the red LED will turn on.
Several preliminary tests were performed, including an alert testing computer simulation using keypads, the DigiAlerter emulator on the microprocessor, and the POC hardware.
A standard keypad entry device was interfaced with a PC using specially written software to produce a LCAS similar in operation to the TII DigiAlerter. The LCAS generates random codes of selected length and type (numeric, alphanumeric, or letters only) at random intervals on a screen to the user (representing the locomotive engineer) whose task is to repeat the code by entering it on a keypad in order to reset a timer which will then delay for a randomly chosen interval. At the end of this interval the process is repeated. If the user fails to enter the code within a specified time or if he/she enters an incorrect character, the system switches into an alarm mode. When this happens, the user must enter another randomly selected code correctly using the keypad a specified number of times within a specified time period in order to cancel the alarm mode. If the user fails to complete the required sequences in the alarm mode, the alarm will be activated. The program written for this experiment specified that the train would automatically be stopped (as when the braking system is put into emergency mode when the conductor activates the emergency brake).
A series of controlled laboratory experiments were conducted, using LCAS. The experiments involved four independently tested male subjects aged 22-26 years to investigate the concepts and alertness criteria and to determine the optimum characteristics of the response required to verify alertness. Since the job of operating a locomotive is variable in its cognitive demands and does not require a fixed posture or eye focal point, the task used to simulate this job consisted of engaging the subject in a group conversation with three other male participants while also providing background music. Other normal computer related activity (conversation, printing laboratory reports, etc.) was present in the surrounding area.
It was determined experimentally that a recommended alertness test protocol, consisting of a visually presented six-letter string, be keyed in using a standard alphanumeric keypad, possibly with an audio or visual signal indicating that the test is being made. Failure to respond correctly or within 13.35 seconds would result in the activation of a signaled alarm mode requiring the correct entry of two additional six-letter codes. Failure to perform this second level task would result in intervention or a stream of cool air being blown into the engineer's face, possibly from several angles. It was estimated that the alertness test should be given every 10-30 minutes during long runs across sparsely populated areas.
The software emulation test was carried out simultaneously with hardware design. After a random delay, the program displays a variable length code consisting of letters and numbers. The user then has a fixed amount of time to respond by selecting the correct digits from the simulated keypad using the mouse. If the user enters the code correctly within the specified time limit, the program waits a random amount of time before displaying a new code. If the user enters the code incorrectly or takes too much time to respond, the program enters the alert mode. The user must in this case correctly respond to a user-specified number of random codes to prevent the system from setting off a simulated alarm (a buzzer). If the correct code is entered each time, the program will return to normal operation, waiting a random amount of time before displaying a new code. If the user fails to enter in each code correctly, the program will inform the user that an error has occurred. Following each session, the program records the results of the simulation to a file. These results include: the user's identification number, the length of the generated codes, the probability of occurrence of letters, the correct character and missed character (in the case of a failure), the time the user required to respond to each code, and a result code. The data file is particularly useful in determining the optimum parameters for the final hardware implementation of the DigiAlerter.
The POC hardware model was tested for operability and functionality. Considering the attributes of a viable CabAlerter, the POC tests and the construction and operability tests of the POC model of the DigiAlerter have shown that the selected alerter is technically feasible and commercially viable.
The feasibility evaluation shows that:
- Physical soundness: The DigiAlerter POC model is compact and portable and can be further reduced in size by burning all controls on a chip. Although the device is relatively rugged, the prototype can be further ruggedized for field use. Tamper proofing of the device can be easily achieved due to the limited entry points and the simplicity of the design. The box itself can be well sealed or formed by a plastic mold that will not allow reaching the internals without destruction of the casing. The low cost of the device will allow for such an option. The use of microchips adds another layer of safeguarding against deliberate tampering. Ruggedness and tamper proofing will be provided in the prototype model in Phase II.
- Compatibility with existing equipment and alert systems: Although the POC model was not designed to interface with other systems (except with a computer), the DigiAlerter can be programmed to interface with telecommunication systems and intervening equipment (e.g. braking system). Failure to properly respond to the alerter can produce a signal through appropriate leads to the proper destination for actuation of an alarm or control system. The DigiAlerter can be easily retrofitted in existing alert systems (e.g. audible or visual alarms). If desired, it can be connected to a deadman switch for validation. All interfaces will be designed and tested in Phase II.
- Compatibility with cab layout and operation area: The compactness of the DigiAlerter allows the location of the device within easy reach of the engineer while he/she is seated in a normal working position. Several locations in the cab have been considered to allow visibility under all operating conditions and to avoid obstruction of the view of other displays or controls. The portability and compactness of the device will provide many possibilities. In fact, a locomotive engineer may prefer one location over another that provides him/her convenient access that is more suited to his/her physical attributes. In Phase II recommended locations will be provided.
- Operability: The DigiAlerter POC model is simple and easy to operate; however, the sequence of operation is not systematic and does require alertness. The use of touch buttons and keypad configurations is becoming part of several daily activities. The simulations and emulation showed that the keypad type of device is the easiest to operate and is the most reliable in operation compared to the other devices whether in use or proposed. Operation of the device causes no distraction from other operating tasks. Matching alphanumerics is moderately challenging, but not frustrating. Random change of the displayed numbers/letters after every use is relatively stimulating and prevents the alert test from becoming boring or routine. The touch pad manipulation to match the display involves cognitive action. In case of an inadvertent error, the engineer can recover and enter the correct response within a short window of time.
- Functionality: The DigiAlerter POC model cannot be simply bypassed or rigged for self-response. Additional safeguard tamper proofing will be provided in the design and construction of the prototype. Currently, the POC model has a simple built-in virtual award and penalty system. Other systems may be considered for the prototype. Both provide feedback stimuli to the engineer's action. The device simplicity makes the alertness test brief without the need for special skills or training. However, sufficient cognitive demand is provided to prevent execution of the test in a semiconscious state as in turning off an alarm clock. The demand does not interfere with other operating tasks by causing distraction. In Phase II simple prototype interfaces will allow for interacting with intervening activity (to alert the engineer or stop the train) should this be necessary. The device simulation has shown a capability to indicate a level of alertness necessary for operating a locomotive engine. The number of allowed attempts before sounding the alarm establishes the threshold for acceptable operation and the limitation on the processing time. Failure or success in the alert test is independent of the cause of non-alertness, whether it is induced by sleep, drowsing, or intoxication.
- Design appropriateness: The DigiAlerter POC model design is simple and reliable. The constructed model has clear displays and controls. Clarity will be improved in the prototype to minimize visual and cognitive demands. The use of an EPROM makes the programming of the device simple, but requires subject-matter-expert. The layout design does not require prolonged postural stress to operate.
- Compatibility with cab operation environment: The rugged casing provides some protection from severe weather extremes and from dust (from sanding of wheels for traction), fumes, odors, etc. However, additional protective measures may be necessary to ensure high performance when the device is subjected to high thermal stresses. The location and installation of the device in the cab will affect its ability to withstand high levels of noise and vibration. These are easily implemented and will be part of the activity in Phase 2.
- Cost competitiveness: The cost of production of the DigiAlerter is low. The touch buttons (or touch surface) is likely to wear out from frequent use. The life of the surface will be shortened if used with soiled fingertips. In general the device life may not exceed five years with heavy use. Overhauling may be limited to change of the casing. However, the low capital cost may make replacement more cost-effective. Testing the device operability against a calibrated system is simple and a self-testing feature may be introduced. Testing the electric circuits will be the same as any simple device. Visual inspection of the surface is sufficient. A short service life is not a drawback in the present case due to low replacement cost and because frequent refurbishment or modernization of the system will contribute to its utility in testing of alertness.
- Acceptability: The team for Phase I included railroad engineers with over thirty years experience. The input and responses to this new alerter system assures the acceptance, by the end users and their Union, of this new addition to the train cab.
- Further Applications: In addition to its obvious utility in the railway industry for maintaining operator alertness, the DigiAlerter has further applications in other areas requiring alertness, such as the airline industry, the entire transportation service industry, security companies, and the military. The DigiAlerter was designed with these multiple applications in mind and was consequently designed so as to be easily modifiable to suit its use in any particular setting.
Based on the POC model, the results of the tests, and the feasibility estimates, a prototype alerter was designed for implementation in Phase II. Also, plans are provided for Phase II, which will involve demonstration of the alerter in an actual moving environment. The DigiAlerter prototype planned for Phase II must perform the following functions:
- Test the alertness of the locomotive engineer.
- Provide stimulus, such as a cool air stream, scented mist, etc., in the event initial tests indicate lack of alertness.
- Take over train control function and notify central command post in the event of failure of the operator to respond. This will result in complete stopping of the train.
The concept for stimulation of the engineer has been established, options include cool air stream, scented mist, etc. Actuation signals are available in the POC model. Phase II will incorporate the appropriate refreshing system and the interfaces with other cab equipment and devices. In addition, Environmental Qualification (EQ) must be performed. This requires consideration of the operability of the DigiAlerter in the locomotive cab environment as well as the ability of the engineer to smoothly interact with the device. The prototype design and construction in Phase II will accommodate for EQ factors in selection of the type and resolution of the display as well as the surface of the keypad (protected buttons versus membrane switch touchpad).

Publication:Abdo A, Husseiny and Y. Aksoy (November 1996). Establishment of Technical Services Centers and Industrial Workshops for the Oil Sector: A Feasibility Study. TII-VA report TILA-96005-SOIK.
Summary
The idea of establishment of technical service centers and industrial workshops has been floating around in the oil sector for some time. In line with this idea, this study presents a formal analysis of the establishment of a new private workshop for maintenance and spare parts needs of the oil sector.
While we focused on the needs of the oil sector due to its dominance in our economy, the proposed facility would also serve other markets, such as power and private industries. A major portion of maintenance and repair work is done in-house in oil sector. High tech jobs are either done overseas or on-site in Kuwait by overseas contractors. Most of the maintenance contracts are for manpower. While 95% of the top and the middle management are Kuwaitis, the technical employees are mostly expatriates. The oil sector has not yet given high priority to systematic technical training and utilization of the national workforce.
We observed an increase in demand for oil in global and local markets. Working with the oil sector we assessed the demand for a new workshop in the market. Demand for spare parts manufacturing is limited to small items whose production does not require high technology. The option of buying is still optimal for the more complex items.

Project Manager / Technical Monitor: Dr. Essam Yahia Omar Alfilaly
Summary
The aim of this project is to investigate the potential of establishing research schools at King Abdulaziz University as multidisciplinary groups to perform diversified research in selected areas of importance to the country, the region and the welfare of the world and the human race. The capital of the research schools is primarily the University human resources and hence faculty members and young researchers will be encouraged to participate in the research conducted in different schools. Areas of excellence at the University would be grouped together into few schools, wherein optimal utilization will be assured of the natural and cultural resources of the Kingdom. Each school will have at least one Nobel Laureate to guide the researchers and become a source of inspiration to them and the new generation of researchers. This is in addition to drawing on the internationally distinguished subject matter experts.
The project will develop the structure of the schools, their goals, mission, vision and objectives. In addition, the relationship with the University and other academic programs will be established to assure no conflict or duplication in the efforts of the research schools, the research institutes and the academic departments at the University. In the same time difficulties in implementation will be assessed.
