THE OBJECTIVE OF THE PROPOSED WORK IS TO USE ADVANCED THEORETICAL AND COMPUTATIONAL TECHNIQUES FOR STUDIES OF HYPERSONIC BOUNDARY LAYER STABILITY AND TRANSITION TO TURBULENCE. THESE STUDIES WILL ENHANCE OUR UNDERSTANDING OF THE TRANSITION PHENOMENA AND THUS HELP PREDICT AND CONTROL TRANSITION WITH A HIGH DEGREE OF CONFIDENCE. TO ACHIEVE OUR GOAL, WE USE LINEAR STABILITY THEORY, SECONDARY INSTABILI ...

A NEW APPROACH TO ALKALI BATTERY DEVELOPMENT, WHICH CAN SATISFY THE DEMANDING HIGH RATE, HIGH SPECIFIC ENERGY SPACE MISSION REQUIREMENTS, IS PROPOSED. THE PROPOSED APPROACH OFFERS SPEPCIFIC ENERGY PERFORMANCE COMPARABLE TO THE BEST RECHARGEABLE LITHIUM BATTERY CHEMISTRIES CURRENTLY UNDER DEVELOPMENT, WITH SUBSTANTIAL INCREASES IN SPECIFIC POWER. THIS PROPOSAL DESCRIBES A PHASE I BATTERY CONCEPT FE ...

THIS OBJECTIVE OF THIS PROJECT IS TO DEVELOP AND BUILD A PROTOTYPE OF A DC TO DC VOLTAGE CONVERTER TO BE USED IN ELECTRONIC FOIL INITIATOR APPLICATIONS. THE DC TO DC CONVERTER WILL WORK AT 80% EFFICIENCY USING CURRENT MODE CHARGING. THE WORKING VOLTAGE WILL BE 2.5 KV WITH AN OVERALL POWER DENSITY OF 25 WATTS PER CUBIC INCH. THE DC TO DC REQUIRES AN DYNAMIC ENVIRONMENTAL INPUT FOR CHARGING. THIS UN ...

A THREE-DIMENSIONAL, NONHYDROSTATIC CLOUD MODEL IS USED AS A TOOL TO INVESTIGATE THE PROBLEM OF THUNDERSTORM INITIATION. OPERATIONAL NUMERICAL MODELS DO A POOR JOB OF PREDICTING THE GEOGRAPHIC DISTRIBUTION OF CONVECTIVE ACTIVITY, ESPECIALLY DURING THE WARM SEASON, WHEN THE LARGE SCALE CIRCULATION IS RELATIVELY WEAK. THE CUMULUS PARAMETERIZATION SCHEMES USED IN CURRENT MESO-BETA-SCALE RESEARCH MODE ...

MRC PROPOSES TO DEVELOP A SAFETY PERFORMANCE INDICATOR (PI) OF THE ELECTROMAGNETIC (EM) PROTECTION STATUS OF A NUCLEAR POWER PLANT (NPP). WE BELIEVE THAT SUCH A PI IS NEEDED BECAUSE: (1) EM ENVIRONMENTAL POLLUTION IS ON THE INCREASE,(2) ADDITIONAL EM THREATS MUST BE EVALUATED, AND (3) DISRUPTION OF NPP OPERATIONS BY EM EFFECTS CAN AND MUST BE AVOIDED. PREVIOUS STUDIES HAVE ADDRESSED THE ISSUE OF E ...

PREVIOUS RESEARCH EFFORTS CONCERNING THE COGNITIVE PERFORMANCE OF THE MEMBERS OF COMMAND AND CONTROL (C2) TEAMS IN DISTRIBUTED, COMPUTER-MEDIATED SYSTEMS HAVE FOCUSED ON MODIFICATIONS OF SYSTEM DESIGN TO ENHANCE COGNITIVE PERFORMANCE. MYSTECH PROPOSES A COMPLEMENTARY EFFORT THAT FOCUSES ON INNOVATIVE C2 TEAM TRAINING METHODS TO IMPROVE COGNITIVE PERFORMANCE. THE RESEARCH WILL FOCUS ON A SPECIFIC C ...

METHODS OF INTEGRATING ANALYTICAL AND EXPERIMENTAL TECHNIQUES TO PREDICT ELECTRONIC DEVICE RESPONSE TO VIBRATION AND SHOCK LOADINGS ARE PROPOSED. UNIQUE NONINTRUSIVE EXPERIMENTAL TECHNIQUES, COUPLED WITH ADVANCED DIGITAL SIGNAL PROCESSING ALGORITHMS, WILL BE USED TO VERIFY FINITE ELEMENT MODEL INPUT DATA, MODELING ASSUMPTIONS, BOUNDARY CONDITIONS, AND TO DETERMINE MATERIAL PROPERTIES SUCH AS DAMPI ...

ION BEAMS WILL BE APPLIED IN SEVERAL ASPECTS OF PROCESSING ZNSE OPTICAL COMPONENTS. FIRST THE MATERIAL WILL BE MILLED, AND THEN IT WILL BE COATED USING ION ASSISTED DEPOSITION TECHNIQUES. REDUCED SCATTER FROM THE SUBSTRATE AND IMPROVE OPTICAL AND MECHANICAL PROPERTIES OF THE FILM ARE ANTICIPATED.

THE GOAL OF THIS PROGRAM IS TO IDENTIFY SPECIFIC NEURAL NETWORK ARCHITECTURES AND ALGORITHMS WHICH ARE APPLICABLE TO COMMUNICATIONS PROBLEMS AND EVALUATE THOSE ARCHITECTURES AND ALGORITHMS VIA SIMULATION AND MODELING. WE DEFINE HEREIN A SYSTEM CONSISTING OF TWO DIFFERENT NEURAL NETWORK PARADIGMS WHICH ARE INTEGRATED TO PERFORM AUTOMATIC IDENTIICATION AND DEMODULATION OF DIGITAL COMMUNICATIONS SIGN ...
