ONE KEY PROBLEM IN MAKING LOW ABSORBANCE MEASUREMENTS IS THERANDOM NOISE GENERATED IN VARIOUS SYSTEM COMPONENTS SUCH AS PHOTODETECTORS, ETC. ANOTHER CLASS OF PROBLEMS ARE ENVIRONMENTAL IN ORIGIN, SUCH AS AIRBORNE OR SAMPLE-BORNE CONTAMINATION, AND SCHLIEREN EFFECTS. THE PROPOSED INSTRUMENT, BASED ON WELL KNOWN WAVELENGTH MODULATION TECHNIQUES, BUT NOVEL IN CERTAIN CRITICAL ASPECTS, SUBSTANTIALLY R ...

THE EVIDENCE FOR NEOTECTONIC ACTIVITY WILL BE STUDIED THROUGH THE INVESTIGATION OF CHANGES IN STREAM CHANNEL MORPHOLOGY, REVIEW OF GEOLOGIC LITERATURE AND OIL COMPANY EXPLORATION LOGS, AND THE USE OF NATIONAL GEODETIC SURVEY FIRST ORDER RELEVELING DATA. THESE THREE DATA SOURCES WILL ALLOW CORROBORATION OF INTERPRETATIONS FROM INDEPENDENT SOURCES OF INFORMATION. PRIMARY OBJECTIVES OF THE PROPOSED S ...

THE EPITAXIAL GROWTH OF NOVEL II-VI SOLAR CELL STRUCTURES WILL BE INVESTIGATED. IN PHASE I, THE METAL ORGANIC CHEMICAL VAPOR DEPOSITION (MOCVD) PROCESS PARAMETERS AND ASSOCIATED GROWTH CHEMISTRIES FOR AN EPITAXIAL P-I-N, ZNTE/CDTE/GAAS, SOLAR CELL STRUCTURE WOULD BE DEVELOPED. THE SOLAR CELL STRUCTURE WOULD BE GROWN AS A CONTINUOUS STRUCTURE WITHIN A SINGLE PROCESS REACTOR. FILM THICKNESS AND COMP ...

THE POLYCHLORINATED BIPHENYLS ARE A HIGHLY STABLE FAMILY OF COMPOUNDS THAT HAVE ACCUMULATED IN THE ENVIRONMENT OVER THE PAST 50 YEARS AT SITES OF THEIR PRODUCTION, USE, STORAGE, OR DISPOSAL. THEIR PERSISTENCE IN SOIL AND SEDIMENT AND POSSIBLE EFFECTS ON HUMAN HEALTH HAVE SPARKED AN INTENSE INTEREST IN DEVELOPING A SAFE, ECONOMICAL MEANS FOR THEIR DESTRUCTION. IT IS OUR GOAL TO USE RECOMBINANT DNA ...

LARGE SCALE APPLICATION REQUIREMENTS FOR HIGH TC CERAMIC SUPERCONDUCTORS (HTSCS), IN ADDITION TO HIGH CURRENT DENSITY, INCLUDE HIGH MECHANICAL STRENGTH AND CHEMICAL AND MECHANICAL STABILITY. MULTICOMPONENT HTSC LAMINATES WITH JC GREATER THAN 1000 A/CM2 AT 77 KELVIN FABRICATED BY THE CONTRACTOR ADDRESS THESE REQUIREMENTS. ELECTRODEPOSITION FROM A NON-AQUEOUS SOLUTION OF THE METAL CLADDING LAYER IN ...

THIS PROPOSAL DESCRIBES A PROJECT FOR DEVELOPMENT OF A PORTABLE CRYOGENIC COOLER FOR RADIATION DETECTORS THAT WEIGHS LESS THAN 10 KG COMPLETE WITH A ONE WEEK SUPPLY OF CRYOGEN, IS SELF REGULATING IN CRYOGEN CONSUMPTION TO PROVIDE RAPID COOL DOWN OR RESPONSE TO TRANSIENT DEMANDS WHILE MAINTAINING MINIMUM CONSUMPTION DURING STEADY STATE OPERATION, REQUIRES NO ELECTRICAL POWER, AND HAS NO CRITICAL MO ...

THE DEVELOPMENT OF NEW TECHNIQUES FOR SAFE CONVERSION OF HAZARDOUS COMPOUNDS RANKS AS HIGHEST PRIORITY IN THE WASTE TREATMENT INDUSTRY. THE DOMINANT PROCESS FOR TOXIC WASTE TREATMENT, SPECIFICALLY CHLOROCARBONS, HAS BEEN INCINERATION. THE INTOLERABLE QUANTITIES OF POLYCHLORINATEDHALOCARBONS (PCHC) DETECTED IN EFFLUENT OF INCINERATORS HAVERAISED SERIOUS CONCERNS AS OF THE WIDE APPLICATION OF THIS T ...

QUANTITATIVE INDICATORS OF COMPANY TECHNOLOGICAL STRENGTH WOULD BE OF ENORMOUS VALUE TO THE CORPORATE AND FINANCIAL COMMUNITIES FOR COMPETITOR ASSESSMENTS, FOR MERGER/ACQUISITION ANALYSIS, AND IN THE GENERAL AREA OF CORPORATE TECHNOLOGICAL PLANNING AND MANAGEMENT. TODAY SUCH INDICATORS ARE ALMOST NONEXISTENT. THE PHARMACEUTICAL INDUSTRY PROVIDES A UNIQUE ARENA FOR EVALUATING VARIOUS ASPECTS OF COR ...

RESEARCH INTO THE AREA OF AUTOMATICALLY PARALLELIZING PROGRAMS FOR DISTRIBUTED MEMORY ARCHITECTURES IS INADEQUATE. CURRENT MODELS OF PARALLELIZATION IGNORE THE PROBLEMS ASSOCIATED WITH THE DISTRIBUTION OF DATA STRUCTURES AND THE CORRESPONDING COMMUNICATION OVERHEAD. THE OBJECTIVE OF THIS RESEARCH IS TO ESTABLISH MECHANISMS FOR THE AUTOMATIC DISTRIBUTION OF FORTRAN PROGRAMS FOR A LOOSELY-COUPLED, M ...
