WE PROPOSE AN EFFICIENT AND COST-EFFECTIVE QUERY PROCESSING COMPONENT FOR AN INFORMATION RETRIEVAL SYSTEM BASED ON THE USE OF NETWORKED MICROCOMPUTERS AS A LOOSELY-COUPLED NETWORK DATABASE. THE QUERY PROCESSSING SYSTEM WILL WORK ON BOTH LOCAL AND WIDE AREA NETWORKS AND CAN BE USED WITH ANY METHOD OF INFORMATION RETRIEVAL. WE PROPOSE TO: 1. MODEL THE EXPECTED PERFORMANCE OF THIS SYSTEM SO THAT IT M ...

Field Programmable Gate Arrays (FPGAs) are growing in popularity due to their high performance capabilities and reprogrammable nature well-suited for development of specific high-speed processing applications. However, the design process for FPGA implementation is time-consuming with multiple complexities that stem from the numerous steps involved, each with a separate CAD tool, requiring the inv ...

We propose to develop a critical enhancement to an existing interactive task guidance system, integrating the capability to utilize data from sensors and control actuators. The system will allow caregivers or rehabilitation professionals to incorporate sensors and actuators into a task script in order to detect task state; detect user state; detect environmental context; detect safety risks; or pa ...

Fully autonomous, taskable robots for use in unconstrained environments are still a dream rather than a reality because of a host of problems, including capabilities of existing sensors, effectors, and control/planning software. Indeed, concepts of operations for robot use are tending toward robots collaborating directly with humans, in relationships similar to bomb squad dogs. Fortunately, enough ...

SYSTEM LEVEL DESIGN DECISIONS ARE KEY TO MULTI-COMPONENT SYNTHESIS: THE DETERMINATION OF WHERE TO SPLIT THE FUNCTIONALITY AMONG COMPONENTS HAS A GREAT EFFECT ON THE SIZE AND PERFORMANCE OF THE DESIGN. BY PARTITIONING A BEHAVIOR ONTO SEPARATE MODULES EARLY IN THE DESIGN PROCESS, THE PHYSICAL IMPLICATIONS CAN BE PROPAGATED TO LATER DESIGN STAGES. DASYS PROPOSES TO DEVELOP A TOOL TO AID IN THE DESIGN ...

Research is proposed to investigate the feasibility of a path planning module that makes use of time-bounded lattices to avoid potential collisions in dynamic environments. The challenge of planning in a dynamic environment is two-fold. First, tracking and predicting the trajectories of dynamic obstacles (e.g., cars, humans, and aircraft) is very noisy. Second, planning with dynamic obstacles requ ...

ING AND CRACK ARRESTING LAYER DESIGNS ARE APPROPRIATE.

LARGE, HIGH QUALITY CDZNTE SINGLE CRYSTALS AREREQUIRED AS HGCDTE EPITAXIAL SUBSTRATES IN THE MANUFACTURE OF INFRARED FOCAL PLANE ARRAYS. BRIDGMAN GROWTH PROCESSES ARE CURRENTLY EMPLOYED TO PRODUCE MATERIALS WHICH MEET SOME APPLICATION REQUIREMENTS, BUT FALL SHORT IN MANY STATE-OF-THE-ART EPITAXIAL HGCDTE DEVICES. BRIDGMANTECHNIQUES, BEING MELT PROCESSES, ARE STRONGLY INFLUENCED BY INTRICATE COUPLI ...

This proposal describes the application of a mature nanotechnology-based crack arrest / structural repair technology as a novel crack arrestor tool for high-strength pipelines. The crack arrestor would comprise a thin layer or sleeve of electrodeposited nanocrystalline material applied to the outside of the pipe either in the coating mill during fabrication or in-field during or following constru ...

This proposal describes the application of a mature nanotechnology-based crack arrest/structural repair technology as a novel in-field pipeline repair tool. The repair would be comprised of a thin layer or sleeve of electrodeposited nancrystalline material applied to the damaged region of the pipe in order to utilize the "crack filling" characteristic of the process. The concept proposed has alr ...
