Users Guide to the HVACSIM+ Configuration Tool

September 2, 2020
Author(s)
Michael A. Galler
HVACSIM+ (HVAC SIMulation PLUS other systems) was introduced by the National Institute of Standards and Technology (NIST) in 1985 as a computer simulation tool to simulate building systems. The HVACSIM+ computer program package and manuals have been

Overshoot Mitigation Using the Reference Governor Framework

January 12, 2020
Author(s)
DJ Anand, Hamid Ossareh, Collin Freiheit
This paper presents a novel reference governor scheme for overshoot mitigation in a tracking control system. Our proposed scheme, referred to as the Reference Governor with DynamicConstraint (RG-DC), recasts the overshoot mitigation problem as a constraint

Modeling Core-Hole Screening in Core-Excitation Spectroscopies

October 16, 2008
Author(s)
Eric L. Shirley, J A. Soininen, J J. Rehr
We consider screening of the core-hole potential experienced by the ejected electron in core-excitation processes. This potential affects near-edge structure strongly, but it appears difficult to consistently obtain reliable screened core-hole potentials

Software Architecture of Virtual Environment for Nano Scale Assembly (VENSA)

August 1, 2003
Author(s)
Kevin W. Lyons, Yung-Tsun T. Lee
Virtual Environment (VE) uses various computer-generated media to let a user experience situations that are temporally and spatially prohibiting. The information flow between the user and the VE is bi-directional. The user can influence the environment

Toward Next-Generation Construction Machines

March 4, 2001
Author(s)
Roger V. Bostelman, James S. Albus, William C. Stone
Construction equipment is typically massive and operated manually with minimal use of sensors or computers for measurement or control. Research in the Intelligent Systems and Structures Divisions at the National Institute of Standards and Technology has

Criteria Analysis

October 1, 1999
Author(s)
Neil Christopher, Jim G. Nell
This document describes a research project to recommend a decision tool that the Manufacturing Systems Integration Division (MSID) could use during its strategic-planning process to evaluate which standards activities to support. This paper describes the

4-D/RCS Reference Model Architecture for Unmanned Ground Vehicles

April 1, 1999
Author(s)
James S. Albus
4-D/RCS is the reference model architecture currently being developed for the Demo III Experimental Unmanned Vehicle program. 4-D/RCS integrates the NIST (National Institute of Standards and Technology) RCS (Real-time Control System) with the German

Integral Equations for 3-D Scattering: Finite Strip on a Substrate

November 28, 2008
Author(s)
Egon Marx
Singular integral equations that determine the exact fields scattered by a dielectric or conducting finite strip on a substrate are presented. The computation of the image of such a scatterer from these fields by Fourier optics methods is also shown.

TREC: Continuing Information Retrieval's Tradition of Experimentation

November 26, 2007
Author(s)
Ellen M. Voorhees
This article provides a high-level overview of the history, results and impact of NIST's Text REtrieval Conference (TREC). The article will appear in a special issue of the Communications of the ACM devoted to experimentation in computer science.

Obtaining More Energetic Modelocked Pulses From a SESAM Fiber Laser

July 6, 2020
Author(s)
Nathan Newbury, Laura Sinclair, Ian Coddington, Stefan Droste, Shaokang Wang, chaoran Tu, Seyed E. Jamali, Thomas Carruthers, Curtis Menyuk
Increasing the output power by increasing the pulse energy without increasing the noise level or decreasing the bandwidth is a major optimization goal for femtosecond fiber lasers that produce frequency combs. Here, we perform a computational study to
