A PROPRIETARY APPROACH TO USING MAGNESIUM COMPOSITES FOR FABRICATING REUSABLE HYDROGEN STORAGE MODULES FOR THE NATIONAL AEROSPACE PLANE (NASP), THE X-30, IS PRESENTED. THESE HYDRIDE MATERIALS HAVE THE INHERENT CAPABILITY FOR STORING HYDROGEN AT ROOM TEMPERATURE TO DENSITIES NEARLY TWICE THAT OF LIQUID HYDROGEN. PRELIMINARY EXPERIMENTS INDICATE THAT THESE MAGNESIUM COMPOSITES CAN MAINTAIN THEIR STR ...

HUMAN EXPERTS IN THE FIELD OF RADAR CROSS SECTION (RCS) DATA ANALYSIS ARE SCARCE AND IN HIGH DEMAND, AS ARE THE FACILITIES REQUIRED TO MAKE SUCH MEASUREMENTS. IN ADDITION, THESE FACILITIES ARE VERY EXPENSIVE TO OPERATE AND MANY ARE LOCATED IN REMOTE AREAS WHERE IT MAY BE IMPRACTICAL TO POST A FULL-TIME HUMAN EXPERT. A MEANS OF AUTOMATICALLY VALIDATING THE TEST DATA COLLECTED AT THESE FACILITIES WO ...

INADEQUATE STARTER FEEDS SEVERELY HOLD BACK NEW AQUACULTURE ENTERPRISES SUCH AS PRESENT ATTEMPTS TO RAISE FISHES WHOSE LARVAE DEVELOP FROM SMALL EGGS AND HAVE VERY "DIFFICULT" FOOD REQUIREMENTS. INERT LARVAL FEEDS HAVE NOT SUCCESSFULLYELIMINATED THE STRICT DEPENDENCY ON NATURAL FORAGE DURING THE CRITICAL POST-LARVAL STAGE AFTER YOLK ABSORPTION AND BEFORE THE DEVELOPMENT OF A DIGESTIVE SYSTEM WITH ...

THE EFFECTS OF SEA CLUTTERON SAR IMAGES ARE VERY PRONOUNED AND IMPAIR TARGET DETECTION AND IDENTIFICATION. A TECHNIQUE CALLED CLEAN CAN BE USED TO REMOVE THE EFFECTS OF THE DISCERNIBLE WAVE PHENOMENA PRESENT IN SAR IMAGES, REDUCE SEA CLUTTER INTENSITIES AND IMPROVE TARGET DETECTION. THE PROPOSED CLEAN TECHNIQUE WILL OPERATE ON THE FOURIER TRANSFORM OF THE IMAGE TO REMOVE STRONG SPACIAL FREQUENCY C ...

RESEARCH ON UTILIZING CLASSIFIED CONDUCTING CERAMIC POWDERS SUCH AS TIC, TIB2 AND ZRB2, AND THE CONCEPT OF PERCOLATION AND SUBSEQUENT PTC EFFECTS, TO FABRICATE CERAMIC/POLYMER COMPOSITE THERMISTERS FOR HIGH CURRENT SWITCHES IS HEREIN PROPOSED. THE USE OF VERY CONDUCING POWDERS AND OPTIMIZED PARTICLE SIZE(S) AND DISTRIBUTIONS OF SUCH, SHOULD ENABLE THE DEVELOPMENT OF VERY LOW RESISTIVITY (1 OHM-CM) ...

MCNC PROPOSES A FEASIBILITY STUDY AND EVALUATION OF THREE PROMISING APPROACHES TO THE FABRICATION OF SURFACE TEST STRUCTURES ON SILICON. SURFACE FEATURES ON THE FIRST STRUCTURE WILL BE PRODUCED BY CONTROLLABLY ETCHING THERMALLYGROWN OXIDES. FEATURES ON THE SECOND WILL BE MADE BY ETCHING PIEZOELECTRIC THIN FILMS. USING THE PIEZOELECTRIC FILM AS PART OF A CAPACITOR, STEP-HEIGHT CAN BE VARIED AND PRO ...

A TECHNIQUE FOR OBTAINING TRUSTWORTHY COMPILATION BASED ON A COMPILATION CHECKER (SIMILAR TO A PROOF CHECKER) IS PROPOSED. THE TRANSFORMATIONS USED IN A COMPILER WILL BE FORMALLY SPECIFIED AND VERIFIED USING INTERPRETER EQUIVALENCE METHODS. THE COMPILER WILL BE INSTRUMENTED TO PRODUCE A TRACE OF THE TRANSFORMATIONS APPLIED IN THE COMPILATION OF A GIVEN PROGRAM. THE COMPILATION CHECKER WILL VALIDAT ...

A NUMBER OF COMMERCIALLY-AVAILABLE CAD SYSTEMS ALLOW THE DESIGNER TO REPRESENT A DESIGN ARTIFACT AS A COLLECTION OF FORM FEATURES. HOWEVER, THEIR ABILITY TO RERERESENT DOMAIN-SPECIFIC FEATURES AND DESIGN KNOWLEDGE IS RATHER LIMITED. THE KNOWLEDGE-BASED DESIGN SYSTEMS, ON THE OTHER HAND, OFFER KNOWLEDGE REPRESENTATION FACILITIES, SUITABLE, IN PARTICULAR, FOR IMPLEMENTING AUTOMATIC PREDICTIONS OF MA ...
