THE USE OF HIGH ENERGY (E~ 1-5 MeV) ELECTRON BEAMS (HEEB) AT HIGH AVERAGE POWER (P~200 kW - 1MW) ALLOWS THE INTRODUCTION OF DEEP-LAYER COMPRESSIVE STRESSES (Q~100,000 PSI) INTO THE SURFACE OF ADVANCED STRUCTURAL CERAMICS. SURFACE STRESS LEVELS OF THIS MAGNITUDE WILL RESULT IN A SIGNIFICANT ENHANCEMENT OF BEND STRENGTH, REDUCING FRACTURES RELATED TO THE AS-FABRICATED SURFACE DEFECT POPULATION. CERA ...

SCIENTIFIC APPLICATIONS AND RESEARCH ASSOCIATES (SARA), INC. PERSONNEL, UNDER INTERNAL PRIVATE FUNDING HAVE DEVISED AN INNOVATIVE CONCEPT FOR SOLVING THE DIFFICULT PROBLEM OF DETECTING ENEMY FOOT SOLDIERS IN A JUNGLE ENVIRORNMENT. EXPLOITING THE UNIQUE PHYSICAL PHENOMENA OF THE SUB-VERY LOW FREQUENCY (S-VLF) REGION OF THE ELECTROMAGNETIC SPECTRUM, TOGETHER WITH RECENT ADVANCES IN INTEGRATED ELECTR ...

LARGE MULTI-USER DATABASES ARE ALREADY ONE OF THE MOST SIGNIFICANT APPLICATONS OF COMPUTERS, AND THEIR IMPORTANCE WILL ONLY GROW AS WE ENHANCE OUR ABILITIES TO AUTOMATICALLY GENERATE AND CAPTURE HUGE AMOUNTS OF DATA. USERS INCREASINGLY WILL DEMAND ACCESS TO VERY LARGE DISTRIBUTED KNOWLEDGE BASES THAT CAN ASSIMILATE VAST QUANTITIES OF INFORMATION FROM MULTIPLE DIVERSE SOURCES WHILE STILL PRESENTING ...

WHILE COMPUTER SPEEDS HAVE BEEN DOUBLING EVERY COUPLE OF YEARS, THE PROCESS OF SOFTWARE DEVELOPMENT TENDS TO PROCEED IN THE SAME WAY AS BEFORE, ONE LINE OF CODE AT A TIME. CONCURRENT SOFTWARE DESIGN ATTEMPTS TO CHANGE THAT SEVERAL TEAM MEMBERS, OR DESIGNERS, WORK SIMULTANEOUSLY TO DEVELOP A SINGLE SOFTWARE PRODUCT. CONCURRENT DESIGN IS EXPECTED TO CUT THE DEVELOPMENT TIME SIGNIFICANTLY. SUCCESSFUL ...

IN THIS PROPOSAL, WE PRESENT AN INNOVATIVE TECHNIQUE FOR MULTISPECTRAL SIGNAL PROCESSING USING MULTICHANNEL ACOUSTO-OPTIC BRAGG CELLS TO SIMULTANEOUSLY PROCESS SPATIALLY AND TEMPORANEOUSLY SEPARATE WIDEBAND SIGNALS. THIS OPTICAL SYSTEM WHEN USED IN CONJUNCTION WITH A CONVENTIONAL SPREAD-SPECTRUM RECEIVER WILL BE ABLE TO IDENTIFY AND ACQUIRE THE CODE OF THE TRANSMITTING EMITTER. THE PROCESSOR WILL ...

THIS PROPOSAL DESCRIBES THE RESEARCH NEEDED TO DESIGN A UNIFIED ACCESS INTERFACE THAT FACILITATES ACCESS TO METEOR BURST, HIGH FREQUENCY, AND LIGHTSAT CHANNELS. IT ALSO PROPOSES THE USE OF AN ASYNCHRONOUS TRANSFER MODE (ATM) CELL-BASE ARCHITECTURE TO PROVIDE MULTIMEDIA SERVICES USING THESE CHANNELS. THE MODULAR DESIGN OF THE UNIFIED INTERFACE STEMS FROM THE FACT THAT USER SERVICE PROFILES ARE CARE ...

DURING COMPLEX ENGINEERING EFFORTS, THE DEFINITION AND CONTROL OF REQUIREMENTS IS TYPICALLY ACCOMPLISHED THROUGH A LARGE SET OF PROJECT DOCUMENTS. TODAY, MANUAL METHODS ARE USED TO HANDLE THESE REQUIREMENTS. THIS HOWEVER, RESULTS IN PROBLEMS IN VARIOUS AREAS SUCH AS MAINTENANCE, TRACEABILITY, AND THE EVALUATION OF THE POTENTIAL IMPACT OF DESIGN CHANGES. THE OBJECTIVE OF THIS PROPOSAL IS TO DESIGN ...
