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 ...

CURRENT DESIGNS OF AIR FORCE HARD TARGET PENETRATING WEAPONS PLACE THE FUZE WELL IN THE TAIL OF THE WEAPON. THIS LOCATION CAUSES SOME DIFFICULTY FOR A SMART FUZE ALGORITHM TO DISCRIMINATE BETWEEN FLEXIBLE BODY WEAPON RESPONSE AND THE LOADING EFFECTS CAUSED BY THE PENETRATION OF SOIL OR CONCRETE. THE AFT LOCATION ALSO LEADS TO CATASTROPHIC FUZE FAILURE WHEN THE WEAPON EXPERIENCES A "TAIL SLAP." CHA ...

THE PRIMARY TECHNIQUES FOR CONDUCTING VULNERABILITY ANALYSES OF MOBILE OR FIXED TARGETS ARE (1) PROBABILISTIC STUDIES USING SIMPLIFIED METHODOLOGIES TO MODEL THE ENTIRE SYSTEM OR PROBLEM AND (2) FIRST PRINCIPLES FINITE ELEMENT OR HYDROCODE CALCULATIONS THAT MODEL DETAILED PHYSICAL INTERACTIONS AND STUDY A SPECIFIC PROBLEM OR PORTION OF A PROBLEM. BOTH TYPES OF ANALYSES REQUIRE A DETAILED TARGET MO ...

FUTURE COMBAT VEHICLES WILL EMPLOY MODULAR ARMOR PROTECTION SYSTEMS THAT CAN BE CHANGED TO MEET DIFFERENT THREAT LEVELS. THESE ADVANCED ARMOR UNITS WILL BE MOUNTED AND DISMOUNTED FROM THE BASIC VEHICLE STRUCTURE, AS NEEDED TO MEET PROTECTION REQUIREMENTS. THE OBJECTIVE OF THIS EFFORT IS TO DEVELOP INNOVATIVE ATTACHMENT CONCEPTS AND METHODS FOR MOUNTING THE MODULAR ARMOR PROTECTION UNITS TO THE BAS ...

AstroPower is developing a two-junction monolithic tandem solar cell composed of (AlxGa1-x)0.51In.49P lattice matched to GaAs for use as the top cell in a three-junction, two-terminal tandem stack. This tunable bandgap material system is capable of current matching, at 2.03eV, in a two-junction monolithic tandem solar cell two terminal design of (AlxGa1-x)0.51In0.49P/GaAs yielding a best case pred ...

ASTROPOWER IS PROPOSING THE DEVELOPMENT OF AN ULTRA-LIGHTWEIGHT, HIGH PERFORMANCE, THIN LIGHT TRAPPING GAAS SOLAR CELL FOR ADVANCED SPACE POWER SYSTEMS. A THIN DEVICE LEADS TO HIGHER PERFORMANCE IN TERMS OF OPEN CIRCUIT VOLTAGE, RADIATION RESISTANCE, AND SPECIFIC POWER. IN A THIN DEVICE, THE INCORPORATION OF LIGHT TRAPPING TO EXTEND THE OPTICAL PATH LENGTH PERMITS GREATER CURRENT GENERATIC THAN CA ...

THE INCREASING SPEED AND COMPLEXITY OF MODERN (AND FUTURE) AIR-VEHICLE SYSTEMS ARE PUSHING THE HUMAN OPERATOR TO HIS LIMITS, ESPECIALLY IN COGNITIVE-RELATED TASKS. IT IS THEREFORE OF PARTICULAR IMPORTANCE TO DEVELOP TECHNIQUES THAT ALLOW THE COMPUTER TO HELP THE HUMAN TO EXTEND THESE LIMITS. AN IMPORTANT CLASS OF SUCH ENABLING TECHNOLOGIES IS AN ACTIVE, MIXED-INITIATIVE MAN-MACHINE INTERFACE (MMI) ...

DHWA PROPOSES TO DEVELOP ALGORITHMS FOR LONG-RANGE, PASSIVE TARGET MOTION ANALYSIS (TMA). THE ALGORITHMS WILL USE EXTENDED FILTERS SIMILAR TO THOSE FOUND IN CURRENT ALGORITHMS (JASA, MPKAST, AND MTST), BUT WILL UNIFY AND EXTEND THESE TECHNIQUES IN IMPORTANT WAYS. WE HOPE TO ELIMINATE MOST OF THE PROBLEMS ASSOCIATED WITH CURRENT METHODS. THE DIFFERENCES AMONG CURRENT ALGORITHMS, AND THEIR LIMITATIO ...

THE PROPOSED PROJECT IS TO DEVELOP AN INFORMATION SYSTEM FOR PROCESSING ECM/ESM CONTACT REPORTS ON BOARD A NAVY SURFACE SHIP. THE SYSTEMWILL COMBINE REPORTS FROM ORGANIC AND REMOTE (0TH) SENSORS WITH OTHER AVAILABLE INFORMATION AND WITH REASONABLE ASSUMPTIONS CONCERNING TARGET TACTICS IN ORDER TO PROVIDE INFORMATION OF VALUE TO THE MISSION COMMANDER. OUR APPROACH IS TO COMBINE TWO EXISTING SYSTEMS ...
