ATOMIC LAYER EPITAXY (ALE) IS A PROMISING GROWTH TECHNIQUE. THE ATTRACTIVENESS OF ALE FOR FUTURE DEVICE AND INTEGRATED CIRCUIT APPLICATIONS CAN BE UNDERSTOOD BY CONSIDERING SEVERAL DESIRABLE ATTRI-BUTES FOR EPITAXIAL GROWTH TECHNIQUES. THESE INCLUDE LOWER DEFECT DENSITY, IMPROVED UNIFORMITY OF THICKNESS AND DOPING, IMPROVED THICKNESS CONTROL, AND THE POSSIBILITY OF CONFORMAL EPITAXY. A MAJOR PROBL ...

RAPID FIRE HIGH VELOCITY AIRCRAFT GUN SYSTEMS HAVE MATURED TO THE POINT WHERE ONLY MARGINAL IMPROVEMENTS IN SYSTEM EFFECTIVENESS, WEIGHT REDUCTION, VOLUME REDUCTION, AND COST EFFECTIVENESS APPEAR ATTAINABLE. MOST OF THESE SYSTEMS ARE EXTERNALLY POWERED GATLING GUNS FIRING METALLIC CASED AMMUNITION, AND THESE COMPONENTS HAVE BENEFITED FROM OVER TWENTY-FIVE YEARS OF DESIGN REFINEMENTS AND MATERIAL I ...

THIS IS A PROPOSAL TO DESIGN, CONSTRUCT, TEST AND DELIVER A LABORATORY BURNER SYSTEM WITH MICROPROCESSOR CONTROL OF FOUR DEGREES OF POSITIONAL FREEDOM (XYZ0) AND OF TWO FLOWRATES. THE BURNER WILL HAVE A UNIVERSAL BASE UPON WHICH LIQUID COOLED BURNER TIPS CAN BE INSTALLED. TWO TIPS, A JET TIP AND A FLAT FLAME TIP, WILL BE PROVIDED UNLESS OTHER TYPES ARE REQUESTED. THE POSITIONING STAGE WILL BE ASSE ...

THE FLUID SITUATIONS ENCOUNTERED ON THE MODERN BATTLEFIELD WILL DICTATE THAT PROVIDERS OF SUPPORT BE RESPONSIVE, FLEXIBLE AND DEMONSTRATE INITIATIVE. THE REALITIES OF OUR AUSTERE LOGISTICS STRUCTURE REQUIRE THAT THEY BE HIGHLY SYNCHRONIZED TO ORDER TO MEET ESSENTIAL NEEDS WITH AVAILABLE RESOURCES. TO MEET THE SUPPORT CHALLENGES THE NEXT BATTLE WILL PRESENT, THE ARMY NEEDS AN AUTOMATED, KNOWLEDGE-B ...

SUCCESSFUL OPERATION OF FUTURE AEROSPACE VEHICLES (E.G. AOTV AND NASP) DEPENDS ON MAJOR ADVANCES IN COMBUSTIONTECHNOLOGY. THE CONDITION OF HIGH FLIGHT-SPEED IMPOSES SEVERE STRAINS ON IGNITION RELIABILITY AND OVERALL COMBUSTION EFFICIENCY. A NOVEL APPROACH TO ALLEVIATE THESE DIFFICULTIES IS PROPOSED. THE INNOVATIVE IDEA IS TO SELECTIVELY IRRADIATE REACTANTS, INTERMEDIATES, INHIBITORS OR SENSITIZERS ...

SORPTION-TYPE HEAT ACTIVATED HEAT PUMPS USING COMPLEX COMPOUNDS AS THE SORBENT MEDIA ARE A VERY PROMISING DEVELOPMENT. THIS PROJECT ADVANCES AN INNOVATIVE STAGING TECHNIQUE THAT GREATLY INCREASES THE COEFFICIENT OF PERFORMANCE (COP) ACHIEVABLE WITH COMPLEX COMPOUND SORPTION CYCLES. THIS STAGING METHOD IS THE FIRST CONCEPT IN WHICH MORE THAN THREE EFFECTS ARE PRACTICAL. INCREASES IN HARDWARE REQUIR ...

PHASE I AIMS TO DEMONSTRATE THE FEASIBILITY OF FABRICATING PREFORMS FOR CERAMIC COMPOSITE SHAPES OF INTEREST TO FOSSIL ENERGY BY USING PROPRIETARY THREE-DIMENSIONAL BRAIDING TECHNOLOGY. HIGH PERFORMANCE CERAMIC COMPOSITES, OPERATING IN EXTREME CONDITIONS OF TEMPERATURE AND CORROSIVE ENVIRONMENT, REQUIRE PREFORM ARCHITECTURES THAT CAN PROVIDE TOUGHNESS, STRENGTH, AND A CAPACITY TO ELIMINATE FAILURE ...

A NOVEL CLASS OF COMPOSITIONS WILL BE USED FOR PREPARING RADIOGRAPHIC FILM FOR MONITORING FAST NEUTRON DOSE AND FIELDPOSITION DURING THERAPY TREATMENT. THE OBJECTIVES OF THIS STUDY ARE TO: (1) DEMONSTRATE THAT SUCH COMPOSITIONS UNDERGOA COLOR CHANGE WHEN EXPOSED TO 10 TO 500 RAD OF FAST NEUTRONS; (2) DETERMINE EFFECTS OF DOSE, DOSE RATE, AND ENERGY OF NEUTRONS; AND (3) SHOW THAT FILMS MADE FROM TH ...

THE PROPOSED RESEARCH WILL TEST A NOVEL AND FUNDAMENTALLY DIFFERENT APPROACH TO CALCULATIONS OF AEROELASTIC AND STRUCTURAL RESPONSE OF COMPRESSOR AND TURBINE ENGINE ROTORS.THE FIRST PHASE OF THIS EFFORT WILL ATTEMPT TO DEMONSTRATE THE FEASIBILITY OF COUPLING A FINITE DIFFERENCE EULER CODE TO A GENERAL PURPOSE FINITE ELEMENT CODE, USING A MIXED EULERIAN-LAGRANGIAN FORMULATION. PART OF THIS WORK CON ...

COMPUTER GENERATED HOLOGRAMS ARE FINDING APPLICATIONS IN AREAS OF ARTIFICIAL INTELLIGENCE RESEARCH, OPTICAL COMPUTING AND TEST LENS FABRICATION. HOWEVER, RESEARCH HAS BEEN HAMPERED BY THE LACK OF AN AFFORDABLE AND PRACTICAL DESK-TOP SYSTEM CAPABLE OF PRINTING COMPUTER GENERATED HOLOGRAMS OF THE PROPER SIZE AND RESOLUTION. SILHOUETTE TECHNOLOGY HAS DEVELOPED A NEW TECHNOLOGY TO MAKE AN AFFORDABLE, ...
