Fault Classes and Error Detection in Specification Based Testing

February 1, 1998
Author(s)
David R. Kuhn
Specification based testing relies upon methods for generating test cases from predicates in a software specification. These methods derive various test conditions from logic expressions, with the aim of detecting different types of faults. Some authors

Selection of Calibration Particles for Scanning Surface Inspection Systems

August 8, 1996
Author(s)
George W. Mulholland, Nelson P. Bryner, Walter S. Liggett Jr, B W. Scheer, R. K. Goodall
In response to the semiconductor industry's need for both smaller calibration particles and more accurately sized larger particles, a joint SEMATECH, National Institute of Standards and Technology, and VLSI Standards, Inc. project was initiated to

Analysis and Prediction of Air Leakage Through Door Assemblies

June 9, 1988
Author(s)
Daniel Gross, W L. Haberman
A generalized relationship is presented for determining air flow rates through narrow gaps around door edges. The relationship provides values of leakage rates for steady, laminar flow through gaps over a wide range of pressure differences and eliminates

High-Precision Optical Time and Frequency Transfer

May 2, 2025
Author(s)
Emily Caldwell, Theodora Triano, Laura Sinclair
High-precision optical time and frequency transfer is accomplished by a collection of laser-based techniques that achieve time dissemination with sub-picosecond instabilities and frequency dissemination with instabilities below one part in 1016. The

Report on High Energy Arcing Fault Experiments - Experimental Results from Low Voltage Switchgear Enclosures

December 29, 2021
Author(s)
Gabriel Taylor, Anthony D. Putorti Jr., Scott Bareham, Christopher U. Brown, Wai Cheong Tam, Edward Hnetkovsky, Andre Thompson, Michael Selepak, Philip Deardorff, Kenneth Hamburger, Nicholas Melly, Kenneth Miller
This report documents an experimental program designed to investigate High Energy Arcing Fault (HEAF) phenomena for low-voltage metal enclosed switchgear containing aluminum conductors. This report covers full-scale laboratory experiments using

Analytical Advances in the SEM

January 1, 2003
Author(s)
J H. Scott
The scanning electron microscope (SEM) - when equipped with one or more x-ray spectrometers - is undoubtedly one of the most powerful tools ever devised for the chemical analysis of solid samples at micrometer and submicrometer length scales. As a finely

The Platinum Pedigree: A long-read benchmark for genetic variants

October 3, 2024
Author(s)
Zev Kronenberg, Nathanael Olson, Justin Zook, Michael Eberle
Recent advances in genome sequencing have improved variant calling in complex regions of the human genome. However, it is difficult to quantify variant calling performance because existing standards often focus on specificity, neglecting completeness in

Comprehensive Overview of Bottom-Up Proteomics using Mass Spectrometry

June 4, 2024
Author(s)
Yuming Jiang, Devasahayam Rex, Dina Schuster, Ben Neely, German Rosano, Norbert Volkmar, Amanda Momenzadeh, Trenton Peters-Clarke, Susan Egbert, Simion Kreimer, Emma Doud, Oliver Cook, Amit Yadav, Muralidharan Vanuopadath, Martin Mayta, Anna Duboff, Nicholas Riley, Robert Moritz, Jesse Meyer
Proteomics is the large scale study of protein structure and function from biological systems through protein identification and quantification. "Shotgun proteomics" or "bottom-up proteomics" is the prevailing strategy, in which proteins are hydrolyzed

Toward a Standard Data Architecture for Additive Manufacturing

January 16, 2024
Author(s)
Shengyen Li, Shaw C. Feng, Alexander Kuan, Yan Lu
To advance the additive manufacturing (AM) technologies, R&D projects may evaluate new facilities and different processes that need a scalable data architecture to accommodate the progressing knowledge. This work introduces a data pedigree to enable the

Deep Learning Image Analysis of Nanoplasmonic Sensors: Toward Medical Breath Monitoring

November 23, 2022
Author(s)
Yangyang Zhao, Boqun Dong, Kurt D. Benkstein, Lei Chen, Kristen L. Steffens, Stephen Semancik
Sensing biomarkers in exhaled breath offers a potentially portable, cost-effective, and noninvasive strategy for disease diagnosis screening and monitoring, while high sensitivity, wide sensing range, and target specificity are critical challenges. We

A Preliminary Study of RF Propagation for High Data Rate Brain Telemetry

February 11, 2022
Author(s)
Mariella Sarestoniemi, Carlos Pomalaza-Raez, Kamran Sayrafian, Teemu Myllyla, Jari Iinatti
This paper presents the preliminary results of a study on the radio frequency (RF) propagation inside the human skull at several Industrial, Scientific and Medical (ISM) and ultrawideband UWB frequencies. These frequency bands are considered as possible

Measurement of mass of aerosol particles

January 1, 2021
Author(s)
Kevin J. Coakley, Robert Hagwood, Kensei Ehara, Nobuhiko FUKUSHIMA, Kittichote WORACHOTEKAMJORN, Naoko TAJIMA, Hiromu SAKURAI
An aerosol particle mass analyzer (APM) which classifies aerosol particles according to their mass has been developed. Mass distributions of aerosol particles can be measured by the APM combined with a particle counting device. Particle mass that can be

Effect of Teflon(R) Transmittance on Sensitivity of Thermoluminescence Dosimeter Cards

May 20, 2020
Author(s)
Vyacheslav B. Podobedov, Carl C. Miller, Alexander Romanyukha, Andrew Hoy
Thermoluminescence dosimeter cards purchased by the United States Navy in recent years have different radiation sensitivities, e.g. they exhibit a different amount of light per dose unit. Presented tests indicate that the optical transparency of the Teflon

2019 Topical Meeting on Optical Interference Coatings: Manufacturing Problem Contest

December 2, 2019
Author(s)
Catherine C. Cooksey, Daniel Poitras, Li Li, Michael Jacobson
For the Seventh Manufacturing Problem contest, participants were asked to fabricate on a provided N-BK7 substrate a challenging filter with specific s-polarization transmittance spectra at angles of incidence of 10° and 50°, covering a wavelength range

Ceramic Materials and Powder Diffraction

September 15, 2019
Author(s)
Winnie K. Wong-Ng
Contrary to general public’s perception of ceramics as primarily encompassing art work, table ware, porcelain enamels, tiles, and sanitary ware, ceramics cover a broad range of materials and applications. We have attempted to categorize these materials in

Miniature fiber optic acoustic pressure sensors with air-backed graphene diaphragms

March 25, 2019
Author(s)
Douglas A. Olson, Haijun H. Liu, Zhijian Zhang, Yongyao Chen, Wen Zhongshan, Yu Miao, Hyungdae Bae, Qian Dong
