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 ...

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 ...

LIGHT SCATTERED FROM CLEAN SEMICONDUCTOR WAFERS IS DUE TO BOTH SURFACE AND SUBSURFACE DEFECTS. SCATTER FROM SURFACE DEFECTS GENERALLY DOMINATES BY AN ORDER OF MAGNITUDE OR TWO. A METHOD TO SEPARATE SUBSURFACE SCATTER FROM SURFACE SCATTER HAS BEEN FOUND, AND IT IS PROPOSED HERE TO UTILIZE THAT TECHNIQUE TO INDICATE THE LOCATION AND AMPLITUDE OF SUBSURFACE DEFECTS BY COLOR MAPPING THE LOCATION AND I ...

THE GOAL OF THIS PROJECT IS TO DEVELOP TECHNIQUES FOR COMPUTER SPEECH RECOGNITION USING PARALLEL DISTRIBUTED PROCESSING MODELS. THESE MODELS ARE BASED UPON THEORIES OF HUMAN COGNITIVE PROCESSING AND HAVE SEVERAL USEFUL PROPERTIES. THEY ARE VERY EFFECTIVE AND EFFICIENT AT INTEGRATING TOGETHER IMPRECISE INFORMATION, AND THUS FOR INTEGRATING MULTIPLE SOURCES OF KNOWLEDGE FOR SPEECH RECOGNITION. THEY ...

LIFT AND CONTROL CHARACTERISTICS OF A CIRCULAR AIRPLANE EMPLOYING THE COANDA EFFECT WILL BE INVESTIGATED EXPERIMENTALLY AND ANALYTICALLY. A SCALE MODEL WILL BE CONSTRUCTED, INSTRUMENTED AND TESTED FOR LIFT FORCES, VELOCITY AND PRESSURE PROFILES. A FINITE DIFFERENCE METHOD OF ANALYSIS OF THE FLOW OVER THE BODY WILL BE DEVELOPED, USING A PARABOLIC MARCHING TECHNIQUE AND A MIXING LENGTH MODEL WITH EM ...

A PROGRAM IS PROPOSED FOR THE ASSESSMENT OF TECHNIQUES FOR PROVIDING COHERENT OPERATION AND BEAM SYCHRONIZATION IN A DISTRIBUTED SPARSE ARRAY RADAR SYSTEM. THE RADAR SYSTEM CONSIDERED WOULD ADDRESS WIDE AREA SURVEILLANCE MISSIONS AND FUNCTIONS FROM SPACE USING TECHNOLOGY IDENTIFIED IN THE USAF FORECAST II STUDY RECENTLY COMPLETED. THE EFFORT WILL EVALUATE SEVERAL CANDIDATE TECHNIQUES INCLUDING LAS ...

MODERN TACTICAL AIRCRAFT FLYING AT HIGH ANGLES OF ATTACK ENCOUNTER VISCOUS SEPARATION, VORTEX FLOWS, VORTEX BREAKDOWN, UNSTEADY FLOW SITUATIONS AND THEIR EFFECTS ON THE LIFTING SURFACES DOWNSTREAM. IT IS VERY IMPORTANT TO ANALYZE THESE FLOWS IN ORDER TO PREDICT THE STABILITY DERIVATIVES ACCURATELY AND ALSO IT IS HIGHLY DESIRABLE THAT IN THE METHODS PREDICTING THE STABILITY DERIVATIVE OF THESE AIRC ...

THIS PROPOSES PHASE I OF A TWO-PHASE ANALYSIS EFFORT, WHOSE OVERALL OBJECTIVE IS TO INVESTIGATE OPTIONS AND TECHNIQUES FOR SURVIVABLE ADAPTIVE NETWORK FOR A DISTRIBUTED ARRAY OF SPACECRAFT (DAS) SYSTEM, FOR FOLLOW-ON DEVELOPMENT. PHASE I WILL IDENTIFY PROMISING APPROACHES, CONDUCT LIMITED ASSESSMENTS, AND IDENTIFY ISSUES FOR MORE DETAILED INVESTIGATION IN PHASE II. A DAS SYSTEM CONSISTS OF SMALL, ...
