THERMAL MANAGEMENT SYSTEMS FOR HYPERSONIC AEROSPACE VEHICLES MUST SIMULTANEOUSLY MEET THREE CHALLENGING REQUIREMENTS: (1) HEAT MUST BE REMOVED AT VERY HIGH HEAT FLUXES FROM SURFACES SUCH AS THE COMBUSTION CHAMBER WALL AND AERODYNAMICALLY HEATED SURFACES, (2) THE PROPELLANT MUST BE PREHEATED TO VERY HIGH TEMPERATURES PRIOR TO COMBUSTION, AND (3) THE SYSTEM'S SIZE AND MASS MUST BE HELD TO A MINIMUM. ...

THE PROPOSED PRODUCT WILL BE A MICROCOMPUTER-BASED PROGRAM WHICH WILL ASSIST THE COGNITIVE REHABILITATION OF TRAUMATI CALLLY HEAD-INJURED ADOLESCENTS AND ADULTS. THE CORE OF THEPROGRAM WILL BE A REAL-LIFE, REAL-TIME DECISION SUPPORT AND PROBLEM-SOLVING SYSTEM SUITABLE FOR COMMERCIAL AND POPULAR DISTRIBUTION TO BOTH CLINICAL AND EDUCATIONAL SETTINGS DEDI-CATED TO WORKING WITH THE HEAD-INJURED. INIT ...

THE POTENTIAL TECHNOLOGICAL IMPORTANCE OF MULTICOMPONENT ULTRAFINE MICROSTRUCTURES MAKES IT ESSENTIAL TO DEVELOP METHODS OF FORMATION WHICH PERMIT BOTH HIGHER GROWTH RATES AND IMPROVED CONTROL OVER MATERIAL PROPERTIES. WE PROPOSE A NEW TECHNIQUE, "GAS JET DEPOSITION", THAT HAS THE POTENTIAL TO PROVIDE THESE CAPABILITIES AND OTHER ADVANTAGES OVER ESTABLISHED METHODS. IN THIS TECHNIQUE, DEPOSITING A ...

FOR THE REST OF THIS CENTURY, TWO OF THE POTENTIALLY MOST IMPORTANT ADVANCES IN THE "TECHNOLOGY" OF LARGE SCALE SCIENTIFIC COMPUTING ARE SPARSE MATRIX (ITERATIVE) ALGORITHMS AND MASSIVELY PARALLEL PROCESSING. IN THIS PROPOSAL, WE OUTLINE OUR PLANS TO BUILD A SOFTWARE PACKAGE FOR THE CONNECTION MACHINE CM-2 THAT WILL BRING THE POWER OF BOTH ADVANCES TO THE AID OF THE SCIENTIFIC COMMUNITY WITHOUT FO ...

SINGLE EVENT UPSETS (SEUS) INDUCED BY IONIZING RADIATION CONSTITUTE ONE OF THE MOST PRESSING PROBLEMS OF SEMICONDUCTOR TECHNOLOGY. AN UNDERSTANDING OF THE PHYSICAL MECHANISMS ASSOCIATED WITH CHARGE COLLECTION HAS ALREADY FURTHERED THE DEVELOPMENT OF HARDENING PROCEDURES. THIS UNDERSTANDING HAS DEVELOPED, IN LARGE PART THROUGH IMPLEMENTATION OF TRANSIENT NUMERICAL SIMULATIONS OF SEUS. HOWEVER, AT P ...

ACOUSTIC RESONANCE CREATES A PROBLEM WITH BOTH THE OPERATION AND THE DURABILITY OF CURRENT HIGH PERFORMANCE GAS TURBINE AUGMENTORS. FUTURE GAS TURBINES ARE EXPECTED TO HAVE AN EVEN MORE SEVERE ENVIRONMENT FOR AUGMENTOR RESONANCE. THE CURRENT LEVEL OF UNDERSTANDING OF THIS PROBLEM GIVES NO ASSURANCE THAT SATISFACTORY PERFORMANCE CAN BE OBTAINED FROM THE MORE ADVANCED AUGMENTORS WITHOUT MAJOR DEVELO ...
