WE PROPOSE TO DESIGN AND SIMULATE A MASSIVELY PARALLEL DATA COMPRESSION SYSTEM FOR WIDE BAND VIDEO THAT IS CAPABLE OF PROCESSING DATA STREAMS OF 1 BILLION BITS PER SECOND IN REAL TIME. THE WORK PROPOSED HERE PROVIDES THE BASIS FOR A SUBSEQUENT PHASE II PROPOSAL TO BUILD THIS HARDWARE. ANTICIPATED BENEFITS/POTENTIAL COMMERCIAL APPLICATIONS - HIGH SPEED COMMUNICATIONS, MASS DATA STORAGE. KEY WORDS - ...

WE PROPOSE TO INVESTIGATE THE USE OF A CW, FREQUENCY DOUBLED, DIODE-PUMPED SOLID STATE LASER IN THE GENERATION OF WATT-LEVEL BLUE LIGHT, FOR APPLICATIONS TO LARGE-SCREEN PROJECTION DISPLAYS. THE SPECIFIC SYSTEM TO BE STUDIED WOULD BE A 946-NM ND:YAG LASER EMPLOYING AN INTRACAVITY DOUBLING CRYSTAL OF POTASSIUM NIOBATE (KNBO3). SINGLE-FREQUENCY, RING-LASER OPERATION WOULD PERMIT EFFICIENT EXTRACTION ...

THE OBJECTIVE OF THE PHASE I RESEARCH IS TO DETERMINE THE TECHNICAL FEASIBILITY OF THE DEVELOPMENT OF A LONG RANGE RADIOACTIVE PLUME TRANSPORT MODEL/CODE FOR THE NRC. THIS CODE WOULD BE USED TO SIMULATE THE MOVEMENT, DISPERSION, DECAY, AND DEPOSITION OF RADIONUCLIDES RELEASED FROM SEVERE NUCLEAR REACTOR ACCIDENTS, SUCH AS THE CHERNOBYL ACCIDENT. IT IS DESIRED THAT ALL RELEVANT PHYSICAL AND CHEMICA ...

MOCVD IS A UNIVERSALLY ACCEPTED EXPITAXIAL PROCESS FOR THE DEPOSITION OF COMPOUND SEMICONDUCTORS. IN FACT, MANY PRODUCTION FACILITIES ARE IN OPERATION. PRODUCTS INCLUDE MICROWAVE AND MILLIMETER WAVE INTEGRATED CIRCUITS (MMICS), LASER DIODES FOR COMPACT DISC PLAYERS, PHOTOCATHODES FOR NIGHT VISION GOGGLES, AND GALLIUM ARSENIDE AND INDIUM PHOSPHIDE SOLAR CELLS. THE CRITICAL WEAKNESS OF THE MOCVD TEC ...

RECENT TREATY NEGOTIATIONS BETWEEN THE US AND THE USSR PLACE LIMITS ON THE SIZE AND LOCATIONS OF NUCLEAR TESTS. THESE LIMITS ARE PERCEIVED AS POTENTIAL INDUCEMENTS FOR THE USSR TO CONDUCT HIDDEN TESTS OUTSIDE THE TREATY REQUIREMENTS. ONE METHOD OF SECRETLY CONDUCTING TESTS WOULD BE TO PERFORM DECOUPLED TESTS IN LARGE HIDDEN UNDERGROUND CAVITIES. THE US MUST BE PREPARED TO QUICKLY AND EFFECTIVELY I ...

MICRO-ELECTRONIC FABRICATION TECHNOLOGIES HAVE RECENTLY BEEN APPLIED TO PRODUCE NOVEL MICRO-MECHANICAL DEVICES SUCH AS MOTORS, SENSORS, AND ACTUATORS. THEIR SMALL SIZE AND EASY INTEGRATION WITH MICROELECTRONICS INVITE INNOVATIVE RESEARCH, BUT THUS FAR FEW USEFUL APPLICATION CONCEPTS HAVE BEEN DEVELOPED. ONE DEVICE WITH WIDESPREAD APPLICATION WOULD BE AN ELECTRICALLY SUSPENDED MICRO-GYROSCOPE. THE ...

RECENT RESEARCH HAS INDICATED THE POTENTIAL BENEFITS OF AEROASSISTED ORBITAL TRANSFER MANEUVERS FOR REALIZING SIGNIFICANT FUEL SAVING OVER PURELY PROPULSIVE MANEUVERS FOR BOTH COPLANAR AND PLANAR TRANSFER USING APPROXIMATE CLOSED-LOOP GUIDANCE LAWS AND/OR NUMERICAL OPTIMIZATION ALGORITHMS. THIS RESEARCH HAS FOCUSED ON CURRENTLY ENVISAGED TRANSATMOSPHERIC VEHICLES. BASIC RESEARCH IS NEEDED TO INVES ...

Herein, ACX proposes to develop compact, low cost, integrated smart packs for vibration reduction. Each package would include actuators and sensors, drive and signal conditioning electronics as well as simple controllers to yield a self standing solution to vibration problems. The electronics module would be low cost and compact. The pack would run off of standard available power supplies and w ...
