THE ACOUSTIC CHARGE TRANSPORT (ACT) DEVICE IS A RELATIVELY NEW COMPONENT, FABRICATED IN MONOLITHIC FORM ON GAAS, THAT OFFERS TREMENDOUS POTENTIAL FOR CURRENT/FUTURE SIGNAL PROCESSING SYSTEMS. BECAUSE OF ITS NEWNESS, LITTLE SYSTEMS APPLICATION WORK HAS BEEN PERFORMED TO-DATE. THE AREAS OF GREATEST POTENTIAL ARE IN RADAR, SONAR, AND PARTICULARLY, ELECTRONIC WARFARE (EW). IN ORDER TO EXPLOIT THIS DEV ...

THIS PROJECT IS DESIGNED TO DEVELOP A COMPUTERIZED DATA COLLECTION SYSTEM FOR EARLY INTERVENTION PROGRAMS UTILIZING HARDWARE COMMONLY AVAILABLE WITHIN EACH EARLY INTERVENTION CENTER SITE. PARALLEL DATABASE SYSTEMS WILL BE DEVELOPED FOR THREE HARDWARE PLATFORMS, ALL WITH THE ABILITY TO TRANSFER DATA INTO A CENTRAL MICRO-COMPUTER. THREE HARDWARE PLATFORMS ARE COMMONLY USED IN EARLY INTERVENTION SITE ...

THE PROTECTION OF OPTICAL/IR SENSORS OF HUMAN EYES AGAINST LASER THREATS IS AN IMPORTANT UNSOLVED DEFENSE PROBLEM. THE MOST CHALLENGING NEED IS FOR AN OPTICAL LIMITER WITH PICOSECOND RESPONSE IN A FINITE WAVELENGTH BAND AGAINST SHORT PULSE, FREQUENCY-AGILE LASERS. OUR RESEARCH IS DIRECTED TOWARDS DEVICE APPLICATIONS OF NOVEL NONLINEAR OPTICAL LIQUIDS WITH PRECISE INDEX MATCHING PROPERTIES AND LARG ...

HEAVY, MULTI-PLY, LIMITED LIFE LIGHTER-THAN-AIR (LTA) VEHICLE SKINS COULD BE REPLACED WITH A HIGH STRENGTH/TOUGH, GAS IMPERMEABLE 2-PLY ORDERED POLYMER LAMINATE. THIS WOULD RESULT IN FACTORS OF 3 TO 10 REDUCTION IN LTA VEHICLE OR SKIN WEIGHT, WHICH WOULD TRANSLATE LINEARLY TO GREATER PAYLOAD AND RELATED PERFORMANCE. THE PROPOSED PHASE I PROGRAM WILL DEVELOP AN EFFICIENT, RELIABLE AND SIMPLE-TOFABR ...

THE INNOVATION WE PROPOSE IS A NOVEL PRECERAMIC POLYMER ROUTE TO THIN (< 1U) COATINGS OF NITRIDES AND CARBIDES ON GRAPHITE FIBERS TO BE USED IN TITANIUM ALUMINIDE INTERMETALLIC COMPOSITES. IF SUCCESSFUL, THE COATINGS WILL PROVIDE AN EFFECTIVE BARRIER TO FIBER-MATRIX REACTION AT HIGH PROCESSING AND SERVICE TEMPERATURES - A MAJOR CAUSE OF DEGRADATION IN THESE NEW HIGH TEMPERATURE COMPOSITES. THE COA ...

IN A CONVENTIONAL WAR, NEUTRALIZATION OF OPPOSING ARMOR IS A KEY MILITARY OBJECTIVE. TRADITIONALLY, SUCH ACTION IS ACHIEVED BY FIREPOWER. HOWEVER, OTHER METHODS (SOFT-KILL) ARE ALSO AVAILABLE; THESE METHODS HAVE THE ADVANTAGE THAT THEY DO NOT HAVE TO OVERCOME THE PROTECTIVE ARMOR OF OPPOSING COMBAT VEHICLES AND OTHER FIELDED WEAPONS. THE WORK PROPOSED HEREIN IS AIMED AT INVESTIGATING A WIDE RANGE ...

GEO-CENTERS, INC. PROPOSED TO DESIGN, DEVELOP, AND TEST A NOVEL SENSOR SYSTEM FOR WIDE AREA MINES (WAMS) THAT WILL ULTIMATELY DETECT ARMORED VEHICLES AT DISTANCES EXCEEDING 100 METERS. A MAGNETIC SENSOR TECHNOLOGY HAS BEEN DEVELOPED AND DEMONSTRATED WHICH PROMISES TO UNIQUELY COMBINE HIGH SENSITIVITY WITH EXTREME SIMPLICITY, RELIABILITY, RUGGEDNESS, COMPACT SIZE AND LOW COST. PROJECTED SENSITIVITI ...

GEO-CENTERS, INC. PROPOSES TO DEMONSTRATE THE FEASIBILITY OF USING A NEURAL NETWORK TO ANALYZE SEISMIC DATA TO CLASSIFY EARTHQUAKES, NUCLEAR BLASTS, AND CHEMICAL BLASTS. USING TIME AND FREQUENCY DOMAIN INFORMATION FROM IDENTIFIED PHASES A NEURAL NETWORK WILL BE TAUGHT USING DATA AVAILABLE FROM THE CENTER FOR SEISMIC STUDIES. A MULTILAYER NEURAL NETWORK WILL BE EMPLOYED HAVING AN INPUT LAYER, A HID ...
