THIS PROPOSAL IS BROKEN INTO FOUR PROJECTS. THE FIRST PROJ-ECT IS THE IMPLEMENTATION OF A QUICK RETRIEVAL SYSTEM FOR LASER DISCS THAT WILL ALLOW USERS TO RAPIDLY ACCESS LARGE AMOUNTS OF DATA VIA INTERNAL COMPUTER CONTROLLED HASHING TA-BLES EITHER STORED ON THE LASER DISC OR MAINTAINED VIA MAIN-TENANCE SOFTWARE ON OTHER SOTRAGE MEDIA. THE SECON PROJECT CONSISTS OF A LIBRARY OF SUBROUTINES TO ACCESS ...

THE OBJECTIVE OF THIS EFFORT IS TO ASSESS LIGHTWEIGHT STRUCTURAL COMPOSITE MATERIALS WITH GREATLY IMPROVED FLAMMABILITY, SMOKE GENERATION, AND TOXIC FUME GENERATION (FST) PROPERTIES FOR USE IN NAVY INTERNAL SUBMARINE APPLICATIONS. THE MATERIALS TO BE EVALUATED CONSIST OF GLASS REINFORCING FIBERS BLENDED IN A THERMOPLASTIC MATRIX WITH PRECISE FIBER/RESIN VOLUME FRACTION CONTROL. THE THERMOPLASTIC ( ...

RESEARCH ON SEPARATION AND CONCENTRATION OF LUNAR DERIVED MATERIALS IS PROPOSED BASED ON ADVANCED ENERGY DYNAMICS' STATE OF THE ART EXPERIENCE IN DRY ELECTROSTATIC SEPARATION.THE TECHNICAL FEASIBILITY OF SEPARATING THESE MATERIALS INTO A VARIETY OF CHEMICALLY DISTINCT FRACTIONS USING A NOVEL COUNTERCURRENT ELECTROSTATIC PROCESS WILL BE INVESTIGATED. THE ELECTROSTATIC SEPARATOR TO BE USED IS IDEALL ...

THE PURPOSE OF THIS PROPOSAL IS TO DESIGN, CONSTRUCT AND TEST A LABORATORY VERSION OF A PASSIVE CHLOROPHYLL FLUORESCENCE SENSOR SUITABLE FOR MONITORING LARGE AREAS OF VEGETATION (> 1 M2). THE LINE DISCRIMINATOR METHOD WE PROPOSE EXPLOITS A COINCIDENCE BETWEEN AN ABSORPTION LINE OFATMOSPHERIC OXYGEN AND THE R1 LINE OF A COOLED RUBY CRYSTAL,BOTH OF WHICH LIE NEAR THE PEAK OF THE CHLOROPHYLL FLUORESC ...

N/A

ONE OF THE MOST EXCITING GOALS OF THE NASA SPACE PROGRAM IS TO LAND A VEHICLE ON MARS AND CONDUCT PHYSICAL AND CHEMICAL MEASUREMENTS OF THE MARTIAN SURFACE. OF THE VARIOUS ANALYTICAL TECHNIQUES BEING CONSIDERED FOR THE LANDER MISSION, X-RAY FLUORESCENCE ANALYSIS OFFERS THE POSSIBILITY OF PROVIDING THE IN-SITU INFORMATION ABOUT THE CHEMICAL COMPOSITION OF THE PROSPECTIVE SAMPLES WHICH WILL BE SELEC ...

THIS PROJECT WILL PREPARE FOR EVALUATION A MATERIAL WHICH SHOULD DEMONSTRATE SUPERIOR PERFORMANCE IN ABSORBING AND DISSIPATING EXPLOSION SHOCK ENERGY. THE COMPOSITION PROPOSED AND ITS BASIS FOR PERFORMANCE ARE EXPLAINED. SHOCK WAVE TESTING WILL BE UNDERTAKEN; AND BASED ON THE RESULTS, RECOMMENDATIONS WILL BE MADE FOR FUTURE PROJECT DIRECTION.

N/A

DEVELOPMENT OF HIGH SPEED SWITCHES AND SWITCHING SYSTEMS IS CRITICAL TO MEET THE THROUGHPUT AND INTERCONNECTIVITY NEEDS OF EFFICIENT HIGH AND LOW-DATA-RATE FMD AND TDM COMMUNICATION AMONG A LARGE NETWORK. IN A TYPICAL SCENARIO DATA FROM MANY PROCESSORS AND SENSORS MUST BE TRANSMITTED AND ROUTED AT TREMENDOUS RATES FOR EFFECTIVE DECISION MAKING. THE LARGE TIME BANDWIDTH OF THE DATA EMANATING FROM C ...

THE OBJECTIVES OF THE PROPOSAL EFFORT ARE TO IMPROVE THE RELIABILITY AND TO REDUCE THE FABRICATION COSTS OF SINGLE MODE FIBEROPTICS COUPLERS BY: 1. DEVELOPING THICK, SINGLE MODE WAVEGUIDES WITH IDENTICAL CROSS SECTIONAL PROFILE MATCHING THAT OF SINGLE MODE FIBERS; AND 2. LOCATING THESE FIBERS TO WAVEGUIDES, MADE OF ELECTROOPTIC MATERIAL, USING PREALIGNED ETCHED "V" GROOVES IN A GAAS SUBSTRATE. OUR ...
