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.

THE RESEARCH FOR AN ALTERNATE MEANS TO CRT TECHNOLOGY OF GENERATING VISUAL DISPLAY HAS BEEN UNDERWAY FOR YEARS. THE PROGRAM PROPOSED WILL DEFINE A METHOD OF PRODUCING A "CRT" TYPE OF VISUAL DISPLAY USING A LASER SCANNING CONCEPT PREVIOUSLY BASED ON WORK AT APA OPTICS, INC. THE PREVIOUS WORK DEFINED A METHOD OF GENERATING A NONMOVING PART SINGLE AXIS LASER SCAN GENERATOR. THIS PROGRAM WILL INVESTIG ...

USE OF ATOMIC LAYER EPITAXY IS BEING INVESTIGATED FOR GROWING SINGLE CRYSTAL ALGAN LAYERS. THE FORMATION OF NITROGEN VACANCIES IS EXPECTEDTO BE SUPPRESSED BY THE UNIQUE ATOMIC LAYER DEPOSITIONS AND THE EXCITATION OF NH3 GAS BY A LASER SOURCE. THIS SHOULD RESULT IN HIGH QUALITY LARGE AREA SINGLE CRYSTAL LAYERS OF ALGAN WHICH COULD BE USED TO MAKE SOLAR BLIND ULTRA-VIOLET (UV) SENSORS. THESE THIN EP ...

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 ...

THE SAFE, RELIABLE, AND EFFICIENT OPERATION OF NUCLEAR POWER PLANTS REQUIRES ADVANCED OPERATOR DECISION AIDS AS WELL AS CONTROL AND PROTECTION SYSTEMS. A PREDICTIVE EXPERT SYSTEM FOR PLANNING POWER MANEUVERS WILL BE INVESTIGATED AS ONE SUCH OPERATOR AID. IN THE PHASE I WORK THE FEASIBILITY OF THE SYSTEM WILL BE DEMONSTRATED VIA A ROBUST NEUTRONICS MODEL, USING THE TRANSIENT FEW-GROUP NEUTRON DIFFU ...

THE NEED FOR SOPHISTICATED DATABASE MANAGEMENT SUPPORT IN NAVY COMMAND AND CONTROL SYSTEMS CONTINUES TO GROW. HOWEVER, CONVENTIONAL DATABASE MANAGEMENT STRATEGIES AND TECHNIQUES ARE NOT CURRENTLY MEETING THE UNIQUE NEEDS OF NAVY DECISION SUPPORT SYSTEMS, WHICH REQUIRE EXTENDED CAPABILITIES FOR HANDLING UNCONVENTIONAL DATA FORMATS AND TEMPORAL INFORMATION. IN THIS PROPOSAL, AQUIDNECK MANAGEMENT ASS ...

INOSITOL TRISPHOSPHATE (IP3) HAS RECENTLY BEEN SHOWN TO STIMULATE CA(2+) RELEASE IN A VARIETY OF CELL TYPES AND, THEREFORE, MEDIATES SUCH PROCESSES AS MUSCLE CONTRACTION, HORMONE SECRETION, AND LIVER METABOLISM. IN ORDER TO INVESTIGATE THE MECHANISM OF IP3 ACTION AND TO DEVELOP THERAPEUTIC DRUGS THAT ACT BY DUPLICATING OR INHIBITING IP3 ACTION, ONE ESSENTIAL LINE OF RESEARCH IS TO STUDY IP3 BINDIN ...
