THE PROPOSED EFFORT INITIATES RESEARCH TO DEVELOP A SET OF KNOWLEDGE REPRESENTATION TOOLS ADDRESSING THE UNIQUE NEEDS OF INTERDISCIPLINARY TEAMS OF DOMAIN EXPERTS WHO DESIRE TO CREATE AND MAINTAIN SHARED KNOWLEDGE BASES. THE PROPOSED ART-DEKO (ARTIFACT-DESIGN/ENGINEERING KNOWLEDGE ONTOLOGY) TOOLSET WILL PROVIDE INTELLIGENT ASSISTANCE AND MEDIATION TO EXPERTS IN THE COOPERATIVE PROCESS OF DEFINING ...

THIS PROPOSAL IS DIRECTED TOWARD THE PREPARATION OF SOL-GEL DERIVED SILICATE STRUCTURES BY BIOMIMETIC PROCESSES. ORGANOSILICON AND GERMANIUM PROBES WILL BE SYNTHESIZED AND THEIR EFFECTS ON REPRESENTATIVE SPECIES OF DIATOMS WILL BE SCREENED. DIATOMS PRODUCE AN ORDERED DEPOSITION OF AMORPHOUS SILICON DIOXIDE FROM SUPERSATURATED SILICATE SOLUTIONS. ORDERED DEPOSITION OF SILICON DIOXIDE IS A MAJOR OBJ ...

THE MAIN IMPEDIMENT TO THE USE OF PARALLEL AND DISTRIBUTED COMPUTING IS THE LACK OF PROPER HIGH-LEVEL PARALLEL PROGRAMMING ENVIRONMENT. THE POTENTIAL OF PARALLEL MACHINES WILL NEVER BE TAPPED IF THEY CNANOT BE PROGRAMMED EFFECTIVELY AND EASILY. FORTRAN-LINDA IS A PROGRAMMING LANGUAGE FOR BUILDING DISTRIBUTED AND PARALLEL PROGRAMS. IT COMBINES A STANDARD SCIENTIFIC PROGRAMMING LANGUAGE (FORTRAN)WIT ...

IN THE LAST FEW YEARS, THE PERFORMANCE OF MICROPROCESSORS USED IN WORKSTATIONS HAS INCREASED DRAMATICLLY, AND ADVANCESIN VLSI TECHNOLOGY ASSURE CONTINUING PERFORMANCE IMPROVEMENT IN THE FUTURE. SCIENTIFIC COMPUTING ASSOCIATES, INC. HAS MADE SIGNIFICANT PROGRESS IN THE DEVELOPMENT OF AN EFFICIENT IMPLEMENTATION OF THE LINDA COORDINATION LANGUAGE ALLOWING PARALLEL PROGRAMS TO BE RUN ON A NETWORK OF ...

THE ESTABLISHMENT OF GUIDING DESIGN PRINCIPLES FOR THE OPERATION OF QUANTUM CONFINED DEVICES IS NECESSARY FOR MAKING ULTRA-SMALL DEVICES AND FOR PRODUCING MORE FUNCTIONALITY PER UNIT AREA OF CHIP WHEN THE DEVICE SIZE IS UNCHANGED. SUCH GUIDING PRINCIPLES REQUIRE A QUANTUM MECHANICALLY BASED SET OF EQUATIONS THAT INCORPORATE MANY PARTICLE STATISTICS. A MAJOR OPPORTUNITY EXISTS FOR INTRODUCING INTO ...

RECENT ADVANCES IN HIGH TEMPERATURE SUPERCONDUCTING (HTSC) THIN FILM TECHNOLOGY ENABLE THE FABRICATION OF LOW-LOSS COMPONENTS THAT WILL IMPROVE THE COST AND PERFORMANCE OF CHANNELIZED RECEIVERS. CHANNELIZED RECEIVERS ARE USED IN SATELLITE TRANSPONDER, ELECTRONIC WARFARE AND ELECTRONICS INTELLIGENCE APPLICATIONS AND ARE COMPRISED OF A GROUP OF NARROW BAND RECEIVERS THAT COVER INDIVIDUAL SLOTS IN A ...

SIGNIFICANT SIMPLIFICATION OF MICROWAVE PHASED ARRAY ANTENNA SYSTEM ARCHITECTURES CAN BE ACHIEVED WITH HTSC DEVICE TECHNOLOGY. ELIMINATION OF THE LOW NOISE AMPLIFIERS (LNAS) CAN BE ACCOMPLISHED THROUGH REPLACEMENT OF THE GAAS PHASE SHIFTERS WITH LOW LOSS HTSC COMPONENTS. A REDUCTION IN COMPLEXITY LOWERS BOTH SYSTEM WEIGHT ANDCOST. KEY TO HTSC TECHNOLOGY INSERTION IN PHASED ARRAY ANTENNAS IS THE DE ...

The dried blood spot (DBS) method is an alternative to venipuncture. The available data indicates that the DBS method is both precise and accurate for a diverse range of compounds. We discovered that proprietary additives vastly improve extraction of proteins in DBS using electrospray. Our unexpected results appear to dramatically increase analyte recovery concentration while reducing DBS prep, an ...
