Southwest Sciences will develop a novel fire detection technology based on optical spectroscopy, using diode lasers and fiber optics. Rapid, quantitative detection of part per million concentrations (or better) of multiple gases, including carbon monoxide, carbon dioxide, hydrogen cyanide, hydrogen chloride, and a fiber optical distribution network permits one laser to be used for at least 800 di ...

The purpose of the VMIS is to allow manufacturers the luxury of testing and perfecting manufacturing plans long before a single machine tool is turned on and resources are committed. The VMIS will allow the user to select an available machine tool and an available inspection device, specify a proposed inspection plan and a dimensional analysis procedure, and then build and inspect hundreds (or ev ...

SOFTWARE HAS BECOME EXPENSIVE; BY THE YEAR 2000, IT REPORTEDLY WILL BE A 2 TRILLION DOLLAR INDUSTRY WORLDWIDE. TO REDUCE COSTS, IT IS VITAL TO REUSE CODE. OBJECT-ORIENTED (00) LANGUAGES ARE TOUTED TODAY FOR THE EASE WITH WHICH SOFTWARE COMPONENTS WRITTEN IN THEM CAN BE REUSED. DUE TO THIS CHARACTERISTIC (ALONG WITH OTHER BENEFITS FO 00 SOFTWARE), SOFTWARE VENDORS ARE BEGINNING TO WRITE CRITICAL AP ...

THE ADMINISTRATION HAS SET FORTH AN AMBITIOUS AGENDA IN "GOALS 2000" TO IMPROVE EDUCATION WITHIN OUR NATION. PRINCIPLES FROM QUALITY MANAGEMENT CAN PLAY A STRATEGIC ROLE IN HELPING US MEET THESE EDUCATION OBJECTIVES. BY EMPHASIZING THE STUDENT AS THE CUSTOMER AND KNOWLEDGE AS THE PRODUCT BEING DELIVERED, RESEARCH DEVELOPMENT CORPORATION (RDC) PROPOSES A METHODOLOGY FOR IMPROVING EDUCATION, PARTICU ...

ROLE-BASED ACCESS CONTROL (RBAC) IS AN IDEAN WHOSE TIME HAS COME. DAC AND MAC, AS SPECIFIED IN DOD'S LANDMARK ORANGE BOOK, ARE INADEQUATE FOR MANY COMMERCIAL AND CIVILIAN GOVERNMENT ORGANIZATIONS. DAC IS TOO WEAK AND MAC IS FOCUSSED ON CONFIDENTIALITY OF CLASSIFIED INFORMATION. RBAC HAS THEREFORE EMERGED AS A THIRD FORM OF ACCESS CONTROL TO FILL THIS URGENT NEED. ALTHOUGH THERE IS A GROWING CONSEN ...

SOUTHWEST SCIENCES PROPOSES THE DEVELOPMENT OF A DIODE LASER-BASED MOISTURE SENSOR. THE INSTRUMENT DYNAMIC RANGE WILL SPAN WATER VAPOR MIXING RATIOS OF 100 PPM TO BETTER THAN 10 PPB. THE PLANNED INSTRUMENT DETECTS ABSOLUTE WATER VAPOR CONCENTRATIONS USING OPTICAL SPECTROSCOPY WITH A CUSTOM-FABRICATED INGAASP DIODE LASER OPERATING AT 1393 NM. OPTICAL ABSORBANCE MEASUREMENTS ARE MADE USING HIGH FREQ ...

WE PROPOSE TO EXPLOIT THE PROPERTIES OF OUR NEW, FAST, BRIGHT SCINTILLATOR, YAIO3:CE(+3) (YAP), TO CONSTRUCT A DETECTOR FOR PHOTONS WITH ENERGIES FROM 20 KEV TO 3 MEV. AN ARRAY OF THESE INDIVIDUAL DETECTORS WILL SERVE AS THE BASIS FOR A BROAD-BAND Y-RAY DOSIMETER CAPABLE OF MEASURING EXPOSURES FROM 5 MR/H TO 1 R/H AND EQUIVALENT DOSES FROM 5 X 10(-2) TO 10 (+4) MSV/H. THEA ADVANTAGES OF YAP SCINTI ...

RECENT DEVELOPMENTS EMPLOYING OBJECT-ORIENTED DATA MODELS HAVE DEMONSTRATED THE FEASIBILITY OF REPRESENTING COMPLEX AND ABSTRACT CARTOGRAPHIC FEATURES AS COMPOSITES OF SIMPLER FEATURES. SEPARATE DEVELOPMENTS IN NEURAL-NETWORK TECHNOLOGY HAVE SHOWN PROMISE IN RECOGNIZING OR EXTRACTING SPATIAL FEATURES WITHIN SAMPLE DATA SETS. COMBINING OBJECT-ORIENTED AND NEURAL-NETWORKS APPROACHES MAY LEAD TO NEW ...

THE DIFFICULTY IN PREDICTING STRUCTURAL DEGRADATION RATES FOR NUCLEAR POWER PLANT COMPONENTS DUE TO CORROSION AND OTHER FACTORS HAS LED TO THE NEED FOR COSTLY, TIME CONSUMING INSPECTIONS AND INCREASED COST FROM INTENTIONALLY OVERDESIGNED COMPONENTS. THE SITUATION INDICATES A SERIOUS, UNMET NEED FOR A SIMPLE BUT ACCURATE SYSTEM FOR REAL- TIME, IN SITU, NONDESTRUCTIVE ANALYSIS OF NUCLEAR POWER PLANT ...
