A Comparison of Predicted to Measured Photovoltaic Module Performance

June 27, 2007
Author(s)
Arthur H. Fanney, Brian P. Dougherty, Mark W. Davis
Computer simulation models to accurately predict the electrical performance of photovoltaic modules are essential. Without such models, potential purchasers of photovoltaic systems have insufficient information to judge the relative merits and cost

A streamlined, high-volume particle impactor for trace chemical analysis

August 1, 2013
Author(s)
Matthew E. Staymates, Jessica L. Staymates, Jerold Bottiger, Deborah Schepers
The design and characterization of a streamlined, high-volume particle impactor used for trace chemical analysis is presented. The impactor has a single round jet and is designed to operate at a flow rate of 1000 LPM. Computational fluid dynamics was used

In situ fatigue monitoring investigation of additively manufactured maraging steel

April 17, 2020
Author(s)
Edward Garboczi, Todd Henry, Francis Phillips, Daniel Cole, Robert Haynes, Terrence Johnson
This work describes an experimental validation set for assessing the real-time fatigue behavior ofmetallic additive manufacturing (AM) maraging steel structures. Maraging steel AM beams were fabricated with laser powder bed fusion (LPBF) and characterized

Framework for Performance Evaluation of Face, Text, and Vehicle Detection and Tracking in Video: Data, Metrics, and Protocol

Author(s)
Rangachar Kasturi, D Goldgof, K Soundararajan, V Manohar, M Boonstra, V Korzhova, J Zhang, Rachel J. Bowers, John S. Garofolo
Common benchmark datasets, standardized performance metrics, and baseline algorithms have demonstrated considerable impact on research and development in a variety of application domains. These resources provide both consumers and developers of technology

Representing an Artifact Transport System in a Design Repository: A Case Study

July 1, 2000
Author(s)
Robert Allen, Ram D. Sriram, Simon Szykman, Robert J. Fijol
We report on a case study representing the design essence of a prototype ultra-high vacuum artifact transport system (ATS) in an existing design repository (DR). Specifically, we represent engineering geometry, function and assosiated behavior, as well as

SHREC14 Track: Shape Retrieval of Non-Rigid 3D Human Models

June 12, 2014
Author(s)
Afzal A. Godil, Chunyuan Li
We have created a new benchmarking dataset for testing non-rigid 3D shape retrieval algorithms, one that is much more challenging than existing datasets. Our dataset features exclusively human models, in a variety of body shapes and poses. 3D models of

Structural Materials Data Demonstration Project: Resource for Thermal Process Modeling

July 1, 2014
Author(s)
Carelyn E. Campbell, Ursula R. Kattner, Alden A. Dima, Scott Henry, Larry A. Berardinis, Tom Searles, Laura M. Bartolo
Integrated Computational Materials Engineering (ICME)requires the availability of supporting data for modeling across multiple length scales. It also requires robust data schema and input-output protocols. To address these needs, a team working under a

Fire Dynamics Simulator (Version 3): Users Guide (NISTIR 6748)

November 1, 2002
Author(s)
Kevin B. McGrattan, Glenn P. Forney, J E. Floyd, Simo A. Hostikka, Kuldeep R. Prasad
Fire Dynamics Simulator (FDS) is a computational fluid dynamics (CFD) model of fire-driven fluid flow. The software described in this document solves numerically a form of the Navier-Stokes equations appropriate for low-speed, thermally-driven flow with an

NIST Station Nightclub Fire Investigation: Physical Simulation of the Fire

June 1, 2006
Author(s)
Daniel M. Madrzykowski, Nelson P. Bryner, Stephen Kerber
A fire occurred on the night of February 20, 2003, at The Station Nightclub located in West Warwick, Rhode Island. A band that was performing that night, during its performance, used pyrotechnics that ignited foam insulation lining the walls and part of

Simulation of Methanol Combustion in the NIST Reference Spray Combustor

November 1, 2000
Author(s)
D S. Crocker, M G. Giridharan, J F. Widmann, Cary Presser
This paper describes the simulation of methanol spray flame in the NIST reference spray combustion facility, which was predicited using a state-of-the-art, unstructured-mesh CFD code. The code solves the gas-phase equations in an Eulerian frame using the
