THE TREND IN ALL MATERIALS IS TOWARD THE CONTROL OF MICROSTRUCTURE. IN CERAMICS AND CERMETS THE EMPHASIS IS ON THE REDUCTION OF CRYSTALLITE SIZE AND THEREBY ON IMPROVING PHYSICAL PROPERTIES. POWDERS SHOULD BE EQUIZAXED AND LIMITED TO SUBMICRON RANGE, WITHIN A NARROW AND SPECIFIC SIZE DISTRIBUTION. EVEN MORE IMPORTANTLY LARGE QUANTITIES OF POWDERS MUST BE AVAILABLE AT REASONABLE COST. AS PRESENTLY ...

THE ABILITY TO FABRICATE CERAMIC ARMOR ECONOMICALLY IS DEPENDENT UPON SEVERAL FACTORS INCLUDING POWDER COST, FABRICATION TECHNIQUE, AND FINAL MACHINE COST. CANDIDATE CERAMIC SUCH AS TIB (2), AND B (4)C DO NOT SINTER TO FULL DENSITY. THEREFORE, NEAR-NET SHAPE FORMATION IS DIFFICULT AND EXPENSIVE, ESPECIALLY WHERE COMPLEX GEOMETRIES ARE INVOLVED. ART PROPOSES TO UTILIZE NEW POWDER SYNTHESIS TECHNOLO ...

RAPID INTENSE HEATING OF COMPOSITE LAMINATES DUE TO DIRECT ENERGY WEAPONS WILL INDUCE STRONG THERMAL GRADIENTS THAT IN TURN PRODUCE DYNAMIC STRESSES IN THE FORM OF WAVE MOTION. THE OBJECTIVE OF THIS RESEARCH IS TO DEVELOP A MINDLIN PLATE FINITE ELEMENT PROGRAM FOR ANALYSIS OF THE DYNAMIC BEHAVIOR IN A COMPOSITE LAMINATE SUBJECTED TO COMBINED THERMAL/SHOCK AND SIMULATED IN-FLIGHT AERODYNAMIC LOADIN ...

CURRENT COMPUTER SYSTEM APPLICATIONS FEATURE CONTINUALLY INCREASING COMPUTATIONAL RESOURCE REQUIREMENTS WHICH HAVE BECOME UNFEASIBLE OR UNREALIZEABLE USING CONVENTIONAL VON NEUMANN UNIPROCESSOR TECHNIQUES. NON-VON NEUMANN ARCHITECTURES FEATURING MULTIPLE PROCESSING ELEMENTS OFFER SOLUTIONS THAT ACHIEVE THE APPLICATION REQUIREMENTS. HOWEVER, SOFTWARE ENGINEERING TECHNOLOGY REMAINS ORIENTED TOWARDS ...

THIS PROPOSAL ADDRESSES A FEASIBILITY STUDY FOR A FLEXIBLE SET OF TOOLS FOR CONSTRUCTING INTERFACES BETWEEN EXPERT SYSTEMS AND COMMERCIAL DATABASE MANAGMENT SYSTEMS (DBMSS) ON PCS. A GREAT NUMBER OF MILITARY PROBLEMS SUITABLE FOR EXPERT SYSTEMS SUPPORT INVOLVE DATA WHICH IS ALREADY MAINTAINED ON PC'S USING COMMERCIALLY AVAILABLE DMSS. TO BUILD THESE EXPERT SYSTEMS, INTERFACES MUST BE CONSTRUCTED B ...

ARTIFICIAL INTELLIGENCE RESEARCH HAS SHOWN THE IMPORTANCE OF COOPERATING EXPERT SYSTEMS ARCHITECTURES IN THE CONSTRUCTION OF INTELLIGENT PROGRAMS TO ASSIST WITH TASKS RANGING FROM DISTRIBUTED SITUATION ASSESSMENT TO INFERENCE OF PROTEIN STRUCTURE. THE MOST WIDELY ADOPTED IS THE BLACKBOARD ARCHITECTURE, WHICH HAS PROVEN HIGHLY EFFECTIVE IN A NUMBER OF SETTINGS. ONE SIGNIFICANT PROBLEM IS THE DEVELO ...

WE PROPOSE A STUDY OF AN OPTIMAL DESIGN FOR A POWERFUL SINGLE PROCESSOR AND A PARALLEL ORGANIZATION OF SUCH PROCESSORS FOR THE PURPOSE OF SIGNIFICANT IMPROVEMENT OF SUPERCOMPUTER PERFORMANCE. WE PLAN TO DETERMINE THE OPTIMAL DESIGN OF THE LST SINGLE PROCESSOR WITH THE LARGEST POSSIBLE WORD SIZE FROM THE POINT OF VIEW OF CURRENTLY COMMERCIALLY AVAILABLE VLSI TECHNOLOGY. SIMULTANEOUSLY, WE WILL INVE ...

THE OBJECTIVE OF THIS PROPOSED RESEARCH IS TO DEVELOP NEW ANALYTIC METHODS FOR CHARACTERIZING MINE WARFARE EFFECTIVENESS. IT WILL USE A COMBINATION OF A PRIOR KNOWLEDGE OF SEQUENTIAL CHOICE OUTCOMES AND UNCERTAINTY IN SEQUENTIAL OUTCOMES. THE APPROACH WILL BE TO DEVELOP A SEQUENTIAL DESIGN ANALYSIS OF PERFORMANCE FOR INDIVIDUAL MINE FIELDS WHICH FULLY CHARACTERIZES SYSTEM PERFORMANCE LINKED TO OBJ ...
