THIS PROJECT FOCUSES ON THE TWO MOST IMPORTANT ISSUES OF ALL OF COMPUTATIONAL FLUID DYNAMICS: 1) HOW GOOD ARE THE NUMERICAL ANSWERS OBTAINED IN A COMPUTATION? AND 2) HOW CAN THE BEST POSSIBLE ANSWERS BE OBTAINED FOR A FIXED AND LIMITED COMPUTATIONAL EFFORT, BUDGET, OR COMPUTING CAPABILITY? IN GENERAL TERMS THE ANSWERS TO THESE QUESTIONS ARE 1) TO DETERMINE RELIABLE A-POSTERIORI ESTIMATES OF ERROR ...

THE GOAL OF THIS RESEACH PROGRAM IS TO BETTER UNDERSTAND THE RELATION-SHIP BETWEEN OXIDATIVE STABILITY AND STRUCTURE AS IT RELATES TO PERFLUOROPOLYETHERS. WE INTEND TO USE DIRECT FLUORINATION TECHNOLOGY TO PRODUCE SEVERAL NEW PERFLUOROPOLYETHER FLUIDES WHICH CONTAIN UNIQUE ARRANGEMENTS OF CARBON AND OXYGEN IN THE BACKBONE OF THE POLYMER AS WELL AS UNUSUAL PENDANT GROUPS. THE DIRECT FLUORINATION PR ...

NATURAL NEURAL NETWORKS ARE STILL OUR BEST GUIDE TO THE DESIGN PRINCIPLES OF ADAPTIVE, INTELLIGENT COMPUTING ARCHITECTURES. DETAILED KNOWLEDGE OF THE MOLECULAR BIOPHYSICAL STRUCTURES THAT MAKE BRAINS WORK WOULD BE NICE TO HAVE, BUT THAT IS NOT THE ONLY WAY TO EXTRACT NATURE'S SECRETS. THIS PROPOSAL USES THE CONCEPT OF RESONANCE AS THE MEANS TO TUNE THE PARAMETERS OF AN ARTIFICIAL NEURAL SYSTEM (AN ...

THREE FACETS OF A PROGRAM OF RESEARCH AND DEVELOPMENT IN SUPPORT OF AN ADVANCED PILOT TRAINING SYSTEM ARE PROPOSED. THE FIRST FACET IS THE DETERMINATION OF THE REQUIREMENTS FOR AND ELEMENTS OF AN ENTIRELY NEW SYSTEM OF WITHIN SUBJECTS PSYCHOMETRICS DESIGNED TO DEVELOP MEASURES AND TECHNIQUES FOR DIFFERENTIATING BETWEEN ABILITIES AND PERFORMANCE LEVELS OF INDIVIDUALS ON DIFFERENT DAYS. THE SECOND F ...

CRITICAL TO DEVELOPMENT OF A TRANSATMOSPHERIC VEHICLE ARE LIGHT WEIGHT MATERIALS FOR ABOVE 1800 F STRUCTURAL APPLICATIONS. CARBONCARBON COMPOSITES WITH OXIDATION RESISTANCE WILL BE REQUIRED IN A TAW AIRFRAME AS 2500 F HIGH STRENGTH FASTENERS. RESEARCH IN JOINING, REINFORCEMENTS, MATRICES, AND OXIDATION PROTECTION REMAINS. HIGH TEMPERATURE FASTENERS TO WITHSTAND AERODYNAMIC HEATING OF THE AIRFRAME ...

PROJECT GOAL WILL BE TO DEVELOP A FAST ALGORITHM FOR VISUAL RECOGNITION OF OBJECTS IN LOW CONTRAST LIGHTING, PARTIAL VIEW AND SIX DEGREES OF FREEDOM. THE ALGORITHM WILL BE OF THE LOCAL FEATURE FOCUS TYPE. TO DEVELOP THE ALGORITHM I WILL NEED TO ACHIEVE THE FOLLOWING OBJECTIVES: 1. RULES FOR SELECTING IMAGE FEATURE CLUSTERS, 2. RULES FOR IMAGE FEATURE CLUSTER PARAMETER EXTRACTION, 3. MATCH TEST TEC ...

PROTOTYPES OF MULTILAMINATE TRANSPARENCIES HAVING A CLOSED FLUID COUNTERCURRENT FLOW CIRCULATING SYSTEM WITH A THERMOELECTRIC SYSTEM WILL BE ADAPTED IN SEVERAL WAYS TO ACHIEVE: 1) PROTECTION AGAINST INCIDENT IR. 2) REGULATION OF INNER TRANSPARENCY SURFACE TEMPERATURE. 3) DYNAMIC RESPONSIVENESS TO INTENSE INCADESCENT FLASH. 4) SURFACE PROTECTION AGAINST LASER INDUCED OPACIFICATION OF TRANSPARENCY. ...
