SUPER ACCURATE ADAPTIVE COMPUTATIONAL SCHEMES FOR THE ANALYSIS OF FLUID STRUCTURE INTERACTION AND COMPLEX THREE-DIMENSIONAL INTERNAL FLOWS ARE TO BE DEVELOPED. NEW PETROV-GALERKIN FINITE ELEMENT METHODS FOR SOLVING THE NAVIER-STOKES EQUATIONS. COUPLED WITH THE EQUATIONS OF MOTION OF ELASTIC DUCTS AND MANIFOLDS, ARE TO BE DEVELOPED AND USED TO SIMULATE FLOWS IN AEROSPACE PROPULSION SYSTEMS (SUCH AS ...

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 PURPOSE OF THIS RESEARCH IS TO STUDY THE FEASIBILITY OF QUANTIFYING THE EFFECTS OF IREASED AUTOMATION ON THE WORKLOAD AND PERFORMANCE OF THE FEDERAL AVIATION ADMINISTRA-TION'S AIR TRAFFIC CONTROLLER. IN PHASE I, RESEARCH WILL FOCUS ON ADAPTRING OUR CURRENT HUMAN PERFORMANCE MODEL TO REPRESENT THE JOB CHARACTERISTICS OR ATTRIBUTES THAT WILL DETERMINE LEVELS OF WORKLOAD AND PERFORMANCE IN THE AD ...

EACH TIME NASA DEVELOPS A SPACECRAFT, IT DEVELOPS, AT THE SAME TIME, A LARGE BODY OF INFORMATION AND KNOWLEDGE IN THE FORM OF ENGINEERING DATA, SPACECRAFT TEST PROCEDURES, AND OPERATIONAL CONSTRAINTS. UNFORTUNATELY, MUCH OF THIS KNOWLEDGE IS NEVER TRANSITIONED TO OPERATIONS, WHICH FREQUENTLY REINVENTS IT (OR WORSE, NEVER DISCOVERS IT). CTA PROPOSES A SYSTEMS TECHNIQUE, A KNOWLEDGE BASE DICTIONARY, ...

THE UTILIZATION OF INTELLIGENT MAINTENANCE TUTORING SYSTEMS ACROSS A WIDE RANGE OF APPLICATIONS CAN BRING A NEW LEVEL OF ABILITY AND LEARNING. TO DEMONSTRATE THE POTENTIAL INHERENT IN THIS CONCEPT, COMPUTER * THROUGHT WILL BUILD AND DELIVER A SOFTWARE SYSTEM THAT IS A WORKING PROTOTYPE FOR A MAINTENANCE TRAINING SYSTEM FOR ASSISTING PERSONNEL IN FAULT DIAGNOSIS AND REPAIR OF DEFECTIVE M16 INFANTRY ...

RESEARCH ON AN ALTERNATE MATERIAL, ANHYDRITE CALCIUM SULFATE, FOR USE AS CULTCH IN CONSTRUCTING SEED BEDS AND ARTIFICIAL OYSTER REEFS IS HEREIN PROPOSED. GIVEN THE FACTS THAT OYSTER PRODUCTION IN THE UNITED STATES HAS DECLINED GREATLY SINCE 1908 AND THAT NATURAL OYSTERSHELL IS SCARCE AND EXPENSIVE, MOTIVATION FOR USE OF THIS ALTERNATE MATERIAL AS CULTCH INCLUDES ITS CONTINUOUS PRODUCTION, LOW COST ...

TECHNIQUES ARE DEVELOPED FOR THE EFFECTIVE HIERARCHICAL CONTROL OF LARGE-SCALE PROCESSES. INDUSTRIAL PROCESSES ARE USUALLY CHARACTERIZED BY SUCH ATTRIBUTES AS LARGE DIMENSION ALITY, THE INTERACTION OF MANY SUBSYSTEMS, MULTIPLE TIME- SCALES DYNAMIC BEHAVIOR, MODEL UNCERTAINTIES, AND CONFLICT ING PERFORMANCE CRITERIA. USING AS AN EXAMPLE THE CONTROL OFA TYPICAL THERMAL PROCESS, FUNCTIONAL REQUIREMEN ...

THE TRADITIONAL AQUACULTURE IN THE SOUTHERN USA EMPHASIZES THE PRODUCTION OF CATFISH AS THE MAIN CROP ORGANISM. DIVERSIFICATION OF THE GROWING INDUSTRY TO INCLUDE NEW CROPS IS NOW ESSENTIAL FROM A PRACTICAL VIEW. COVENANT AQUACULTURE CORPORATION PROPOSES TO EXAMINE THE PRODUCTION OF THE FRESHWATER PRAWN MACROBRACHIUM ROSENBERGII, AND TILAPIA, IN A POLYCULTURE SYSTEM, IN A PRODUCTION SCHEME SPECIFI ...
