Chapter 13: Economic Analysis and Green Buildings

October 1, 2002
Author(s)
S Fuller
Building economics, value engineering, and cost engineering are the three main fields that explicitly include an economic evaluation in building-related project analyses. The common theme that ties the three disciplines together is that each is concerned

A Hierarchical World Model for an Autonomous Scout Vehicle

April 5, 2002
Author(s)
Stephen B. Balakirsky, Tommy Chang, Tsai H. Hong, Elena R. Messina, Michael O. Shneier
This paper describes a world model that combines a variety of sensed inputs and a priori information and is used to generate on-road and off-road autonomous driving behaviors. The system is designed in accordance with the principles of the 4D/RCS

Amorphous Calcium Phosphate

November 1, 2001
Author(s)
Laurence C. Chow, E D. Eanes
Amorphous structures represent about 20% of the 60 or so different mineral types formed by the action of living organisms. Among these biogenic amorphous minerals, those that are composed principally of calcium and phosphate are most abundant in the teeth

NIST Recommended Practice Guide: Particle Size Characterization

January 1, 2001
Author(s)
Ajitkumar Jillavenkatesa, Lin-Sien H. Lum, Stanley Dapkunas
This guide is a compilation of essential facts and some fundamental information about commonly used techniques of particle size analysis in the ceramics industry. The guide is designed for the non- expert who may have some or little previous knowledge

The Ampere and Electrical Standards

January 1, 2001
Author(s)
Randolph Elmquist, Marvin E. Cage, Yi-hua D. Tang, Anne-Marie Jeffery, Joseph R. Kinard Jr., Ronald F. Dziuba, Nile M. Oldham, Edwin R. Williams
This paper describes some of the major contributions to metrology and physics made by the NIST Electricity Division, which has existed since 1901. It was one of the six original divisions of the National Bureau of Standards. The Electricity Division

Immobilizing a Fluorescent Dye Offers Potential to Investigate the Glass/Resin Interface

January 1, 2000
Author(s)
Joseph~undefined~undefined~undefined~undefined~undefined Lenhart, J H. VanZanten, Joy Dunkers, C G. Zimba, C A. James, S K. Pollack, Richard~undefined~undefined~undefined~undefined~undefined Parnas
Silane coupling agents are commonly applied to glass fibers to promote fiber/resin adhesion and enhance durability in composite parts. In this study, a coupling agent layer on glass was doped with trace levels of the dimethylaminonitrostilbene (DMANS)

Report on High Energy Arcing Fault Experiments: Experimental Results from Medium-Voltage Bus Duct and Switchgear Enclosures

September 15, 2023
Author(s)
Gabriel Taylor, Anthony D. Putorti Jr., Scott Bareham, Christopher U. Brown, Wai Cheong Tam, Ryan Falkenstein-Smith, Stephen Fink, Michael Heck, Edward Hnetkovsky, Nicholas Melly, Kenneth Hamburger, Kenneth Miller
This report documents an experimental program designed to investigate high energy arcing fault (HEAF) phenomena for medium-voltage, metal-enclosed bus ducts and switchgear. This report covers full-scale laboratory experiments using representative nuclear

On-Wafer Calibration Comparisons of Multiline TRL with Platinum and Gold Conductors

July 30, 2024
Author(s)
Tomasz Karpisz, Jacob Pawlik, Johannes Hoffmann, Sarah Evans, Christian Long, Nathan Orloff, James Booth, Angela Stelson
On-wafer calibrations are critical for measurements of embedded devices at the correct reference planes. A major challenge in on-wafer calibrations is the development of accurate calibrations that cover a frequency range from MHz to THz. Another challenge

Measurements of Absolute, SI-traceable Lunar Irradiance with the Airborne LUnar Spectral Irradiance (air-LUSI) Instrument

May 5, 2022
Author(s)
John T. Woodward IV, Kevin Turpie, Thomas Stone, S. Andrew Gadsden, Andrew Newton, Stephen Maxwell, Steven Grantham, Thomas Larason, Steven W. Brown
The Airborne LUnar Spectral Irradiance (Air-LUSI) instrument is designed to make low uncertainty, hyperspectral measurements of the lunar spectral irradiance from an ER-2 aircraft from altitudes above 95 % to 99 % of the atmosphere. Measurements cover the

Advances in Production Management Systems: Issues, Trends, and Vision Towards 2030

August 13, 2021
Author(s)
Boonserm Kulvatunyou, David Romero, Gregor V. Cieminski, Paolo Gaiardelli, Ilkyeong Moon, Giuditta Pezzotta, Stefan Wiesner, Marco Macchi, Jannicke B. Hauge, Irene Roda, Daryl Powell, Torbj?rn Netland, Nick Szirbik, Christoph Roser, Erlend Alfnes, Martin Rudberg
Since its inception in 1978, the IFIP Working Group 5.7 on Advances in Production Management Systems (APMS) has played an active role in the conception, development, and application of innovative strategies, frameworks, architectures, processes, methods

A robust benchmark for detection of germline large deletions and insertions

June 15, 2020
Author(s)
Justin Zook, Nathanael David Olson, Marc Salit, Fritz Sedlazeck
New technologies and analysis methods are enabling genomic structural variants (SVs) to be detected with ever-increasing accuracy, resolution and comprehensiveness. To help translate these methods to routine research and clinical practice, we developed a

Performance Study of a GAA-GAA Coexistence Scheme in the CBRS Band

December 19, 2019
Author(s)
Weichao Gao, Anirudha Sahoo
The General Authorized Access (GAA) users in the Citizens Broadband Radio Service (CBRS) band are the lowest priority users who not only have to make sure that they do not cause harmful interference to the higher tier users but also must cooperate with

High-precision measurement of the X-ray Cu K-alpha spectrum

May 12, 2017
Author(s)
Marcus H. Mendenhall, Albert Henins, Lawrence T. Hudson, Csilla I. Szabo-Foster, Donald A. Windover, James P. Cline
The structure of the x-ray emission lines of the Cu Kα complex has been remeasured on a newly commissioned instrument, in a manner directly traceable to the Système Internationale definition of the meter. In this measurement, the region from 8000 to 8100

3.5 GHz Radar Waveform Capture at Point Loma

May 11, 2017
Author(s)
Paul D. Hale, Jeffrey A. Jargon, Peter J. Jeavons, Michael R. Souryal, Adam J. Wunderlich, Mark Lofquist
We describe measurements to create a library of high-fidelity waveforms of federal incumbent radar signals currently operating in the 3550 MHz – 3650 MHz (“3.5 GHz”) band. In the first phase of assembling this library, measurements were collected at Point
