AN EXPERT SYSTEM REQUIREMENTS AND DEVELOPMENT PROGRAM IS PROPOSED TO ACHIEVE AN EXPERT SYSTEM FOR JOINING COMPOSITE MATERIALS. THE NEED IS TO ASSIST DESIGN ENGINEERS TO ACCESS LARGE AMOUNTS OF JOINT DESIGN AND DATA THAT IS AVAILABLE. THE EXPERT SYSTEM WILL PROVIDE ALPHANUMERIC AND GRAPHICS INFORMATION TO THE DESIGNER TO ASSIST IN THE OPTIMUM SELECTION OF COMPOSITE MATERIALS JOINING TECHNIQUES. THE ...

THE DEVELOPMENT OF COMPACT, HIGH ENERGY DENSITY, HIGH POWER (AND POTENTIALLY C.W.) LASER SYSTEMS CAPABLE OF PROPAGATING THROUGH BOTH AIR AND WATER COULD PAVE THE WAY FOR NEXT GENERATION TACTICAL NAVAL SYSTEMS. APPLICATIONS IN OTHER DEFENSE AREAS AS WELL AS A HOST OF COMMERCIAL APPLICATIONS ARE ALSO POSSIBLE WITH THESE TYPES OF SYSTEMS. WE PROPOSE TO PROVIDE A DETAILED PLAN AND DESIGN OF SPECIFIC E ...

N/A

THE INCREASED DEMANDS FOR LARGE SCALE INTEGRATION AND VERY HIGH SPEED PROCESSING OF INFORMATION HAVE LED TO INCREASING DENSITY OF CHIPS IN ELECTRONIC MODULES. THIS, IN TURN, HAS INCREASED DRAMATICALLY THE HEAT GENERATED PER UNIT AREA. IN ORDER TO MEET THE NEW DESIGN SPECIFICATIONS, AN INNOVATIVE HEAT SINK CONCEPT IS PROPOSED. THE HEAT SINK WILL HAVE A THERMAL EXPANSION IN THE RANGE OF 2.8 PPM/DEG ...

A USER-FRIENDLY COMPUTER CODE WILL BE DEVELOPED TO CALCULATE THE UNSTEADY AND HIGHLY 3-D COMPLEX FLOWPATHS IN EXHAUST DIFFUSERS OF MODERN MARINE GAS TURBINES, INCLUDING PRESSURE LOSSES AND NONUNIFORM FLOW LOSSES. THE VAX-VMS CODE WILL BE BASED UPON AN EXISTING 3-D TIME-DEPENDENT NAVIER-STOKES CODE ALREADY VALIDATED IN THE CALCULATION OF PITCHING OF A SWEPT WING SECTION MOUNTED IN A WIND TUNNEL, AN ...

THIS PHASE I PROJECT WILL RESEARCH THE PROBLEMS, CURRENT OPERATIONS, FILE STRUCTURES, AND DATA COMPRESSION REQUIREMENTS TO FACILITATE THE RAPID ERROR-FREE TRANSMISSIONOF WEATHER MAPS, ALPHANUMERIC WEATHER DATASETS, AND SATELLITE IMAGES. SUPPORTING THE INTERAGENCY FIRE WEATHER PROGRAM, IT WILL ALSO RESEARCH THE COMMERCIALLY AVAILABLE HARDWARE AND SOFTWARE WHICH WILL MEET TRANSPORTABILITY, RELIABILI ...

N/A

A LAMBERTIAN ATTENUATION MODEL WILL BE COMBINED WITH A VERY FAST RAY TRACING ALGORITHM ON A NETWORK OF TRANSPUTER ELEMENTS TO DETERMINE THE APPLICABILITY OF PARALLEL COMPUTING TO EXAMPLE RADIATION TRANSPORT MODELING.

THE OBJECTIVE OF PHAE I IS TO DETERMINE BY AN ANALYTICAL STUDY THE OPTIMUM DESIGN APPROACH, OR APPROACHES, FOR SOLID-STATE ELECTRICAL FAULT CURRENT LIMITERS FOR THE CURRENT RANGE OF 15 TO 5000 AMPERES. THE ANALYTICAL TRADEOFF STUDY WILL INCLUDE THE FOLLOWING TASKS: 1) DEFINITION OF CURRENT LIMITER REQUIREMENTS, 2) DEFINITION OF TRADEOFF ANALYSIS CRITERIA, 3) DEFINITION OF CANDIDATE CURRENT LIMITER ...

THE RESEARCH PROGRAM WILL DEVELOP A MICROCOMPUTER BASED SYSTEM OF HARDWARE AND SOFTWARE WHICH WILL ALLOW THE USER TOEXECUTE MAINFRAME BASED CODES ON THE MICROCOMPUTER. IN ADDITION PARALLEL EXECUTION OF SEVERAL CODES AT ONCE IS POSSIBLEA SPECIAL INPUT AND OUTPUT PROCESSOR MODULES WILL ALSO BE DEVELOPED TO DEMONSTRATE THE USER FRIENDLY CAPABILITIES OF THE SYSTEM AND FACILITATE INPUT PREPARATION AND ...
