Science and Technology: the Challenges of the Future (open access)

Science and Technology: the Challenges of the Future

Preface: On its 80th anniversary, the National Bureau of Standards hosted a series of lectures by six distinguished speakers of national and international note who discussed the challenges facing science and technology and, thus, the Bureau in the coming years. This publication contains the texts of these presentations, along with transcripts of the question-and answer sessions following the presentations. The lecture series was organized by Dr. Donald R. Johnson of NBS with the very able assistance of Mrs. Carol Shipley in making arrangements for speakers and handling the manuscripts. The staff of the NML Text Editing Facility are acknowledged for their substantial contributions of typing and editing support.

Measurement of Electrical Quantities in Pulse Power Systems (open access)

Measurement of Electrical Quantities in Pulse Power Systems

Abstract: The Workshop on Measurement of Electrical Quantities in Pulse Power Systems addressed measurements in pulse systems having the characteristics of pulse duration less than a millisecond, system voltages greater than 10 kilovolts, and system currents greater than 10 kiloamperes. The presented papers were divided into four categories: voltage measurements; current measurements; power and energy measurements, and data acquisition. Included are discussions of applications of conventional measurement techniques and state-of-the-art systems.

Oil and Gas Supply Modeling (open access)

Oil and Gas Supply Modeling

Abstract: The symposium on Oil and Gas Supply Modeling, held at the Department of Commerce, Washington, DC (June 18-20, 1980), was funded by the Energy Information Administration of the Department of Energy and co-sponsored by the National Bureau of Standards' Operations Research Division. The symposium was organized to be a forum in which the theoretical and applied state-of-the-art of oil and gas supply models could be presented and discussed. Speakers addressed the following areas: the realities of oil and gas supply, prediction of oil and gas production, problems in oil and gas modeling, resource appraisal procedures, forecasting field size and production, investment and production strategies, estimating cost and production schedules for undiscovered fields production regulations, resource data, sensitivity analysis of forecasts, econometric analysis of resource depletion, oil and gas finding rates, and various models of oil and gas supply. This volume documents the proceedings (papers and discussion) of the symposium.

U.S. Access to Japanese Technical Literature: Electronics and Electrical Engineering, Selected Presentations, Volume 1 (open access)

U.S. Access to Japanese Technical Literature: Electronics and Electrical Engineering, Selected Presentations, Volume 1

Abstract: On June 24-25, 1985, NBS and IEEE cosponsored a seminar at NBS to examine the need fox improved access to Japanese technical information and to explore possible app. aches to satisfy those needs. To limit the discussion to practical dimensions, the technical subject matter was restricted to electrical and electronics engineering. The program was designed to provide an opportunity for individuals representing Congress, the practicing engineering community, industry, and the educational community to voice their concerns and their needs. This proceedings volume contains selected presentations made at the seminar plus the visual aids used by each speaker.

The Investigation of Fundamental Interactions with Cold Neutrons

Abstract: The National Bureau of Standards is establishing a National Cold Neutron Facility at its 20 MW reactor located in Gaithersburg, Maryland. In order to provide guidance in the development of research plans for the Facility, the Department of Energy and NBS sponsored, on November 14-15, 1985, a workshop on the Investigation of Fundamental Interactions with Cold Neutrons. The 25 papers presented at the workshop are printed in the proceedings.

Evaluating Thermal Fire Detection Systems: English Units (open access)

Evaluating Thermal Fire Detection Systems: English Units

Abstract: This report presents a methodology for evaluating heat detection systems installed in buildings. Previous work for use primarily in designing new thermal fire detection systems was used as a starting point. The previous work was enhanced and supplemented to make it more useful for evaluating existing systems. The resulting equations were programmed into a user interactive computer program. This program is available in both BASIC and FORTRAN and will run on mainframes as well as personal computers. In addition, a modified version of the FORTRAN program was used to develop an extensive set of tables listing detector activation times for given building geometries, detector characteristics, and fire growth rates. These tables are useful for quick evaluation of alternative heat detector installations. Finally practical examples are included to illustrate the use of the tables and computer programs.
