WORK IS PROPOSE TO ASSESS THE FEASIBILTY OF SODIUM\SULFUR-SELENIUM BATTERIES FOR ELECTRICALLY POWERED WEAPONS SYSTEMS ABOARD AIR BREATHING AIRCRAFT AND FOR ENERGY STORAGE ABOARD ORBITAL FLIGHT VEHICLES. SEVERAL POTENTIAL ADANTAGES OF THE SODIUM\ SULFUR-SELENIUM BATTERY OVER THE SODIUM-SULFUR BATTERY ARE POINTED OUT, INCLUDING HIGHER POWER AND ENERGY DENSITIES AND LONGER LIFETIMES. BASED ON SOME PR ...

RECENT ADVANCES IN CONTACT FRACTURE MECHANICS HAVE CREATED AN OPPORTUNITY TO APPLY CONTACT FRACTURE MECHANICS TO INVESTIGATE MECHANISMS OF MATERIAL REMOVAL AND DAMAGE PENETRATION DURING ABRASIVE MACHINING OF CERAMICS. IN PHASE I IT IS PLANNED TO EMPHASIZE INVESTIGATION OF THE MECHANISMS OF MATERIAL REMOVAL INCLUDING CRUSHING BY MIXED MODE FRACTURE AHEAD OF THE DIAMOND POINT AND CHIPPING AT LATERAL ...

THE PROGRAM WILL EXPLORE THE FEASIBILITY OF GROWING SILICON SHEET CRYSTALS HORIZONTALLY USING THE EDGE-SUPPORTED PULLING(ESP) PROCESS FROM SILICON MELTS CONTAINED IN AN RF HEATED CRUCIBLE. THEORETICAL EVALUATION OF THE BASIC HORIZONTAL RIBBON GROWTH (HRG) PROCESS HAVE SHOWN QUITE CONCLUSIVELY THE ENORMOUS POTENTIAL OF THIS CRYSTAL GROWTH METHOD; I.E., IT SHOULD BE POSSIBLE TO PRODUCE LARGE, FLAT S ...

COMPOUND SEMICONDUCTORS SUCH AS GAAS AND INP BASED III-V ALLOYS AND II-VI ALLOYS SUCH AS CDTE AND HGCDTE WILL HAVE WIDESPREAD USE IN DEFENSE-RELATED ELECTRONICS SYSTEMS. A VARIETY OF TECHNIQUES EXIST FOR THE MICROANALYSIS OF CHEMICAL CONSTITUENTS CONTAINED IN THESE MATERIALS. THE PROPOSED RESEARCH WILL EVALUATE AND DEVELOP AN APPROACH FOR THE RAPID, HIGH SPATIAL RESOLUTION CHARACTERIZATION OF COMP ...

THIS PROPOSAL IS TO DETERMINE THE FEASIBILITY OF LASER MICROPROBE MASS ANALYSIS (LMMA) FOR THE QUANTITATIVE CHARACTERIZATION OF BIOLOGICAL MATERIALS. SPECIFICALLY, THE MICROANALYTICAL CAPABILITY OF LMMA WILL BE EVALUATED THROUGH LOCALIZED "IN SITU" ELEMENTAL AND MOLECULAR ANALYSISOF BIOLOGICAL MATERIALS.

THE PRIMARY OBJECTIVE OF THE PHASE I EFFORT IS TO EVALUATE THE FEASIBILITY OF DEVELOPING AN ON-BOARD FLOW-FIELD PASSIVE RANGING SYSTEM FOR USE IN TACTICAL MISSILE GUIDANCE. THE BASIC TECHNIQUE PROPOSED FOR STUDY USES THE FLOW-FIELD INFORMATION IMPLICIT IN ALL PASSIVELY-IMAGED DYNAMIC SCENES, TO DEVELOP EVOLVING AND AUTONOMOUS ESTIMATES OF MISSILE IMPACT TIMES TO ALL TERRAIN POINTS IN THE SEEKER FI ...

THE ADVENT OF ULTRAFILTRATION PROCESSES HAS ALLOWED THE CHEESE INDUSTRY TO PRODUCE HIGH-QUALITY, WHEY-PROTEIN CONCENTRATES FOR USE AS FOOD INGREDIENTS. AT THE SAME TIME,HOWEVER, MORE THAN TWO-THIRDS OF THE WHEY VOLUME IS COLLECTED AS ESSENTIALLY UNUSABLE WHEY PERMEATE CONTAINING 5% LACTOSE AND ACCOMPANYING SALTS. ABOUT 20% BY VOLUME OF THE WHEY REMAINS ASSOCIATED WITH THE CHEESE CURD AND IS EXPELL ...
