We propose a radically innovative approach to the problem of multiple access communication which promises to revolutionize the modern communication industry by dramatically increasing network throughput. Our approach is based upon two major novel components: (i) hybrid time-frequency allication of communication channel resources, and(ii) non-orthogonal, i.e., overlaping, multiplexed signals. Toge ...

This effort will integrate an advanced technology speech recognition system (SRS) with a computer-assisted contingency planning training model. The SRS makes use of algorithms developed in the Speech Technology and Research Labratory of SRI International. Its state-of-the-art approach provides significant improvements in accuracy and robustness over other approaches. It provides for speaker ind ...

Continuing efforts to develop useful and safe means of treating unserviceable, damaged or unused munitions and ordnance include the use of Open Burning/Open Detonation (OB?OD) technique. Although OB/OD techniques provide many advantages over other demil/disposal processes, increasing regulatory scrutiny is forcing OB/O facilities to limit or eliminate operations. In addition, data collection req ...

This project will analyze and select promising materials and designs to be used in the plumes of tactical solid rocket motors for missile steering and control. The emphasis is on high-performance refractory materials and compatibility of material systems. The control fins experience severe thermal and severe particulate erosion environments. Missile controllability requires fins with minimal er ...

Development of new algorithms for improved tracking of MTI data from airborne standoff platforms can be enabled by exploiting additional information extracted from multi-mode radar including both SAR image information and MTI. MTI radar is being increasingly used for tactical battlefield surveillance and several new Systems are reaching ICC which will provide continuous wide area surveillance. T ...

A Phase I project to design and demonstrate the concept of a "high-speed laser scanning technology for the measurement" and reporting of the small fire arm scoring. Accuracy of the measurement is +/- 1 mm over an area of 30'x30' with a projectile velocity of up to 1,550 meter/second. The results of the Phase I program will provide crucial design guidelines for the construction of a full brassboa ...

We propose the application of HEMS technology to the development of a tactile finger tip display device for operation in conjunction with finger force reflective devices. By co~ining high bandwidth finger tip acutation with lower bandwidth, large motion finger force reflection, we hope to gain full range-of-motion dexterity with the impression of sensitive surface touch. For medical diagnostic ...

For the Phase I effort we plan to investigate two potential mutispectral sensor solutions a 3 color reticle system and 2 color imaging system. Each of these sensor soncepts will be analytically modeled and evaluated against the best set of target and background data that is available. This process will be used to identify minimum required sensor configurations in order to solve the Safe-To-Load ...

In the Phase I effort, we will implement a three level modeling approach to provide the basis for an optimized multi-sensor design. The three levels include performance, cost and power. the organization of each level will include provisions for the sensor, processor, transmission and display. the cost and power models will be based on survey of existing technologies using methods outlined below ...
