ACES IS AN INTEGRATED CONTROL SYSTEM WHICH USES CONVENTIONAL AND ARTIFICIAL INTELLIGENCE TECHNIQUES FOR AUTOMATED ASSISTANCE TO THE OPTIMIZATION OF AIR COMBAT COMMUNICATIONS CAPABILITIES. ACES CONTROLLERS ARE ELEMENTS OF EACH COMBAT WEAPONS AND C2 ENVIRONMENTS NODE WHICH CAN SENSE BOTH THE ELECTROMAGNETIC ENVIRONMENT AND THE QUALITATIVE DEMANDS FOR COMMUNICATIONS AT NODES AND WITHIN NETWORKS. ACES ...

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 ...

GENERATOR USED PRIMARY POWER SYSTEMS ARE THE ACHILLES HEEL OF TACTICAL COMMAND AND CONTROL SYSTEMS, FIELD HOSPITALS, AND OTHER TACTICAL SUPPORT FACILITIES. THEY ARE NOISY AND PRONE TO FAILURE AT THE MOST CRITICAL TIMES. TACTICAL POWER USING SYSTEMS HAVE DIFFERENT POWER DUTY CYCLES AND POWER FACTORS. SOME ARE PREDICTABLE; OTHER TOTALLY RANDOM; AND MANY MUST BE DEPENDED UPON IN THE "HEAT OF THE BATT ...

SCOPE PROPOSES TO DEVELOP A DIGITAL SIGNAL PROCESSING CONCEPT FOR THE REALTIME DETECTION AND IDENTIFICATION OF HF EMITTERS AND THEIR PLATFORMS. THIS INVESTIGATION WILL SPECIFICALLY EVALUATE HF EMITTER CHARACTERISTICS AND PHENOMENA OF POTENTIAL INTEREST FOR IDENTIFICATION. SIGNAL PROCESSING TECHNIQUES AND ALGORITHMS WILL BE DEFINED TO EXPLOIT EMITTER AND PLATFORM IDENTIFIABLE SIGNAL CHARACTERISTICS ...

THE TECHNICAL OBJECTIVE OF THIS PROJECT IS TO ESTABLISH THE FEASILBILITY OF SATISFYING THE REQUIREMENTS OF THE U.S. ARMY COMMUNICATIONS ELECTRONICS COMMAND (CECOM) FOR RAPID AND EFFECTIVE MODELING OF U.S. ARMY COMMUNICATION SYSTEMS. THE METHOD WE PROPOSE FOR SATISFYING THESE REQUIREMENTS IS TO ADAPT A TOP-DOWN DESIGN SYSTEM FOR ELECTRONIC SYSTEMS BEING DEVELOPED FOR THE U.S. NAVY TO MODEL-ING OF C ...

CURRENT SHIPBOARD AIRCRAFT SUPPORT EQUIPMENT HAS INADEQUATE CAPABILITY TO RESIST EXPECTED SHOCK LEVELS IN HEAVY WEATHER AND COMBAT OPERATIONS. CAREFUL REVIEW OF THE STATE-OF-THE-ART INDICATES THAT MANY CURRENTLY USED PROCEDURES FOR SHOCK RESPONSE PREDICTION OF SHIPBOARD EQUIPMENT AND FOR SHIP GIRDER RESPONSE TO SHOCK LOADS ARE INADEQUATE BECAUSE OF THE MANY ASSUMPTIONS AND THE OVERSIMPLIFIED MODEL ...

IN RECOGNITION OF THE GROWING SHORTFALL BETWEEN NEEDS AND ABILITIES TO PROVIDE A SAFE AND EFFICIENT AIR NAVIGATION AND AIR TRAFFIC CONTROL SYSTEM, THE FEDERAL AVIATION ADMINISTRATION (FAA) IMPLEMENTED ITS LONG RANGE PLANNING NATIONAL AIRSPACE SYSTEM (NAS) PLAN. THE NAS PLAN CONTAINS A COLLECTION OF MODERNIZATION PROJECTS AFFECTING MOST ELEMENTS OF THE NAS AND POTENTIALLY HAVING SIGNIFICANT IMPCTS ...
