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 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 ...

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 ...

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 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 ...

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 ...

THE REDUCED ENTRAINMENT PRECIPATATOR WILL HAVE IMPROVED COL-LECTION EFFICIENCY FOR DUSTS HAVING EITHER HIGH OR LOW ELEC-TRICAL RESISTIVITIES. THIS OBJECTIVE IS ACCOMPLISHED BY PRO-VIDING A POROUS, FABRIC COLLECTING SURFACE. A SMALL PORTION (TYPICALLY LESS THAN 20%) OF THE DIRTY GAS STREAM IS DRAWN THROUGH THE COLLECTED DUST CAKE AND THE POROUS COLLECTING PLATE BY A SEPARATE FAN. THIS SMALL FLOW TH ...

The use of enzyme-linked immunosorbent assay (ELISA) to detect contaminants such as solvents, fuels, and pesticides in soil and water samples is now well established. Although ELISA and related methods can facilitate analysis of samples, several washing and separation steps are involved that require 30 to 120 minutes per sample to reach equilibrium. Recently, near infrared fluorescence immunoassa ...
