SysML Extension for Logistics Modeling and Analysis (SysLMA)

April 23, 2025
Author(s)
Raphael Barbau, Conrad Bock
Many engineers use analysis tools to predict behavior or find optimal values for properties of systems built to proposed designs, informing system design work by identifying cases where a design will perform incorrectly or in suboptimal ways. Design and

SLowFlowS: A novel flow standard for semiconductor process gases

March 1, 2025
Author(s)
Jodie Gail Pope, Keith A. Gillis, Aaron Johnson, Joey Boyd, John Wright
Numerous process gases are used in the production of semiconductor chips. Accurate metering of these gases into process chambers is critical for maximizing device throughput and yield. A national flow standard for semiconductor process gases does not exist

Mechanical Sensors for Planck-scale Dark Matter Searches via Long-range Forces

February 14, 2025
Author(s)
Jacob Taylor, Juehang Qin, Dorian Amaral, sunil bhave, Erqian Cai, Daniel Carney, Raphael Lang, Shengchao Li, Claire Marvinney, Alberto Marino, Jared Newton, Christopher Tunnell
Dark matter candidates with masses around the Planck-scale are theoretically well-motivated and have been the subject of numerous studies; it has also been suggested that it might be possible to search for dark matter solely via gravitational interactions

Plasmonic Sensing Studies of a Gas-Phase Cystic Fibrosis Marker in Moisture Laden Air

May 29, 2021
Author(s)
Libin Sun, Drew Hall, Douglas Conrad, Kurt D. Benkstein, Stephen Semancik, Mona Zaghloul
A plasmonic sensing platform was developed as a noninvasive method to monitor gas-phase biomarkers related to cystic fibrosis (CF). The nanohole array (NHA) sensing platform is based on localized surface plasmon resonance (LSPR) and offers a rapid data

Author(s)
Timothy A. Sprock, George Thiers, Leon F. McGinnis, Conrad E. Bock
System models and model-based engineering methods have the promise of transforming the way that industrial engineers interact with production and logistics systems. Model-based methods play a role in improving communication between stakeholders

Liquid Viscosity and Surface Tension of n-Hexane, n-Octane, n-Decane, and n-Hexadecane up to 573 K by Surface Light Scattering (SLS)

August 16, 2019
Author(s)
Tobias Klein, Shaomin Yan, Junwei Cui, Joe W. Magee, Kenneth Kroenlein, Michael H. Rausch, Thomas M. Koller, Andreas P. Froba
In the present study, the simultaneous and accurate determination of liquid viscosity and surface tension of the n-alkanes n-hexane (n-C6H14), n-octane (n-C8H18), n-decane (n-C10H22), and n-hexadecane (n-C16H34) by surface light scattering (SLS) in

Utilizing confocal laser scanning microscopy for rapid optical characterization of graphene

November 20, 2018
Author(s)
Vishal Panchal, Yanfei Yang, Guangjun Cheng, Jiuning Hu, Mattias Kruskopf, Chieh-I Liu, Albert Rigosi, Christos Melios, Angela R. Hight Walker, David B. Newell, Olga Kazakova, Randolph Elmquist
Confocal laser scanning microscopy (CLSM) is a non-destructive, highly-efficient optical characterization method for large-area analysis of graphene on different substrates, which can be applied in ambient air, does not require additional sample

Thermal Exposure Sensor for Fire Fighters - full-Scale Performance Experiments

July 26, 2016
Author(s)
Nelson P. Bryner, Atul Deshmukh, John Casali, Jeff Lancaster, Roy A. McLane
During structural fire fighting suppression operations, fire fighters wear protective gear to insulate them from the high temperature environment including hot combustion gases, burning surfaces, and thermal radiation. Current turnout gear insulates the

The Need for Realism when Simulating Network Congestion

April 2, 2016
Author(s)
Kevin L. Mills, Christopher E. Dabrowski
Many researchers use simulation to investigate network congestion, often finding congestion spread can be modeled as percolation, spreading slowly under increasing load until a critical point, then spreading quickly through the network. The researchers

Product Data Sheet Ontology

December 18, 2014
Author(s)
Binyam G. Abeye, Edward J. Barkmeyer Jr., Peter O. Denno
Data exchange transactions for the engineering, procurement, and operation of process equipment depend heavily on product data sheets. Product data sheets are traditional paper forms that serve as the main method of communicating detailed equipment

Progress toward new Reference Correlations for the Transport Properties of Carbon Dioxide

September 10, 2014
Author(s)
Allan H. Harvey, Marcia L. Huber, Arno R. Laesecke, Chris D. Muzny, Richard A. Perkins
The thermophysical properties of carbon dioxide are essential for accurate process design and optimization. While the thermodynamic properties of CO2 are available with excellent accuracy from the reference-quality equation of state of Span and Wagner, the

SCIENCE-BASED METRICS FOR PRODUCT SUSTAINABILITY ASSESSMENT

September 30, 2012
Author(s)
Barbara C. Lippiatt
Consumers and manufacturers need compelling metrics, tools, and data supporting investments in sustainable products. Today’s marketplace is fraught with sustainability claims that are often based on incomplete, anecdotal evidence that is difficult to

Detection of Voigt Spectral Line Profiles of Hydrogen Radio Recombination Lines toward Sagittarius B2(N)

Author(s)
Francis J. Lovas, Azrael A. von Prochazka, Anthony J. Remijan, Dana S. Balser, Robert S. Ryans, Adele H. Marshall, Frederic R. Schwab, Jan M. Hollis, Phil R. Jewell
We report the detection of Voigt spectral line profiles of radio recombination lines (RRLs) toward Sagittarius B2(N) with the 100-m Green Bank Telescope (GBT). These results constitute the first known, unambiguous detection of the Voigt spectral line shape
