THE OBJECTIVES OF PHASE I ARE TO DETERMINE HOW WELL THE SMALL SCALE TESTS CURRENTLY USED FOR SCREENING EXPLOSIVES, AND THE MODELS THAT DESCRIBE EXPLOSIVE BEHAVIOR IN THE SMALL SCALE TEST AND IN THE FULL SCALE MUNITION, CAN PREDICT THRESHOLDS OF EXPLOSIVE REACTION IN THE OPERATIONAL FULL SCALE MUNITION. FULL SCALE MUNITIONS WILL BE STUDIED TO DETERMINE THE CRITICAL MODE(S) OF EXPLOSIVE REACTION THA ...

THE TREND CONTINUES TOWARDS APPLYING ADVANCED COMPOSITE MATERIALS TO THE HIGH PERFORMANCE STRUCTURES ASSOCIATED WITH AEROSPACE. STRUCTURES FABRICATED FROM CARBON-CARBON AND FILAMENT WOUND COMPOSITES ARE PARTICULAR EXAMPLES. TO FULLY EXPLOIT THE PROMISE OF THESE ADVANCED STRUCTURES, NOVEL NDE TECHNIQUES ARE NEEDED FOR CHARACTERIZATION. DUAL-ENERGY LAMINOGRAPHY SPECIFICALLY ADDRESSES THE CHEMICAL, D ...

THE NEED TO APPLY EXPERT KNOWLEDGE IN THE INTERPRETATION OF MEDICAL IMAGERY AND SENSOR DATA IS WELL DOCUMENTED. RULE-BASED EXPERT SYSTEMS HAVE PROVEN THEIR VALUE IN SUCH APPLICATIONS AS MEDICAL EXPERTISE. MOST DIAGNOSTIC SYSTEMS MIMIC THE CONSULTING-ROOM ENVIRONMENT, ACQUIRING SYMPTOM DESCRIPTIONS AND LAB FINDINGS THROUGH DIALOG WITH THE USER. AUTOMATED DIAGNOSIS FROM IMAGERY AND ANALOG IS A MORE ...

THE RESEARCH ADDRESSED IN THIS PROPOSAL INVOLVES AN INVESTIGATION INTO THE USE OF DIAMOND THIN FILMS AS SOLID STATE OPTICAL SWITCHES WHERE THE FILMS ARE PRODUCED BY AN INHERENTLY LOW-COST TECHNIQUE EMPLOYING PLASMA-ENHANCED CHEMICAL VAPOR DEPOSITION (PE-CVD) OF CARBON-CONTAINING GASES (E.G., METHANE). THE OBJECTIVE OF THIS PROPOSED RESEARCH EFFORT IS TO EVALUATE EXPERIMENTALLY THE OPTOELECTRIC PRO ...

THE OBJECTIVE OF THIS PROPOSED RESEARCH EFFORT IS TO EXPERIMENTALLY EVALUATE THE OPTOELECTRONIC PROPERTIES OF CHEMICAL VAPOR DEPOSITION DIAMOND THIN FILMS WITH RESPECT TO ELECTROLUMINESCENCE AND PHOTOCONDUCTION IN THE UV AND BLUE-GREEN SPECTRAL REGIONS. AS A RESULT OF SUCH EFFORTS WE WILL DETERMINE THE EXTENT TO WHICH DIAMOND THIN FILMS MAY BE USED AS LASING MEDIA OR PHOTOCONDUCTORS AND ASCERTAIN ...

MANY EXPLOSIVE WARHEADS ARE SENSITIVE TO INITIATION BY FRAGMENT OR BULLET IMPACT AND SYMPATHETIC DETONATION. DIRECTED-ENERGY WARHEADS IN PARTICULAR ARE OFTEN LOADED WITH VERY ENERGETIC EXPLOSIVE TO OBTAIMANCE AT THE EXPENSE OF INCREASE SENSITIVITY. THE OBJECTIVE OF THE PROPOSED PROGRAM IS TO DETERMINE THE MOST EFFECTIVE APPROACH TO REDUCING THE SENSITIVITY OF AN EXISTING WARHEAD, SUCH AS THE SFW O ...

STORAGE OF ELECTRICAL ENERGY AT A SUFFICIENTLY HIGH DENSITY, IN A SMALL ENOUGH VOLUME AND WITH HIGH ENOUGH EFFICIENCY OF EXTRACTION IS INCRESINGLY BECOMING A SIGNIFICANT PROBLEM. CONVENTIONAL CAPACITIVE DEVICES (E.G., ELECTROLYTIC CAPACITORS) FALL SHORT OF PROVIDING THE VOLUMETRIC EFFICIENCY REQUIRED TO SUPPORT NEW TECHNOLOGIES FOR COMPLEX FUZE REQUIREMENTS. WE PROPOSE TO DEVELOP AN ENERGY STORAGE ...

THIS PROPOSAL ADDRESSES THE DEVELOPMENT OF AN INTELLIGENT TUTORING SYSTEM (ITS) TO TRAIN AIR FORCE PERSONNEL. EXPERT-EASE SYSTEMS (EES) HAS DEVELOPED AND DEMONSTRATED A SUCCESSFUL COMPUTER-BASED INSTRUCTION TECHNIQUE CALLED OPTIMALLY ADAPTIVE LEARNING (OAL). OAL COMBINES SEVERAL TECHNOLOGIES: OPTIMIZATION THEORY, EDUCATIONAL MODELING, AND HUMAN PSYCHOLOGY. THE OAL APPROACH UTILIZED ADVANCED OPTIMI ...

THE EXPERIENCE OF THE PAST THIRTY YEARS IN THE SPACE BUSINESS HAS YET TO BE FULLY EXPLOITED FOR ITS POTENTIAL IN REDUCING SPACE SYSTEMS COSTS. THE PROPOSED EFFORT WILL PROVIDE A METHODOLOGY WHICH WILL PLACE THE PAST EXPERIENCE OF COST REDUCTION INITIATIVES AT THE FINGERTIPS OF THE AIR FORCE MANAGERS. THE METHODOLOGY IS PLANNED TO TAKE THE FORM OF A TWO PART DECISION SUPPORT MODEL CODED FOR A PERSO ...

WE PROPOSE TO DEVELOP A NOVEL SIGNAL PROCESSING ARCHITECTURE FOR THE DISTRIBUTED SPARSE ARRAY (DSA) RADAR. THE SYSTEM IS A SPACE-BASED, THINNED PHASED ARRAY RADAR IN WHICH EACH ARRAY ELEMENT IS A SEPARATE SPACECRAFT (CALLED A MINI-RADAR). MINI-RADARS COOPERATE TO FORM A SINGLE COHERENT RADAR BEAM. THE NEW ARCHITECTURE DISTRIBUTES SIGNAL PROCESSING ALMOST EQUALLY THROUGHOUT THE MINI-RADARS AND ALLO ...
