Golden aspect ratio for ion transport simulation in nanopores

July 5, 2018
Author(s)
Subin Sahu, Michael P. Zwolak
Access resistance indicates how well current carriers from the bulk medium can converge to a pore or opening, and is important in many fields, such as cell biology, electronics, electrochemical engineering, thermal transport, among others. In simplified

THE INTERDEPENDENT NETWORKED COMMUNITY RESILIENCE MODELING ENVIRONMENT (IN-CORE)

June 22, 2018
Author(s)
Paolo Gardoni, John W. van de Lindt, Bruce Ellingwood, Therese P. McAllister, Jong Lee, Harvey Cutler, Daniel Cox
The National Institute of Standards and Technology (NIST) funded the multi-university five-year Center of Excellence for Risk-Based Community Resilience Planning (CoE), headquartered at Colorado State University, to develop the measurement science to

Perceptual expertise in forensic facial image comparison

September 1, 2015
Author(s)
P. Jonathon Phillips, David White, Alice O'Toole, Carina A. Hahn, Matthew Hill
Forensic facial identification examiners are required to match the identity of faces in images that vary substantially, owing to changes in viewing conditions and in a person's appearance. These identifications affect the course and out- come of criminal

Paving the Way for a More Sustainable Concrete Infrastructure: A Vision for Developing a Comprehensive Description of Cement Hydration Kinetics

March 28, 2013
Author(s)
Joseph J. Biernacki, Jeffrey W. Bullard, Constantiner Constantiner, Richard Meininger, Maria Juenger, Josephine H. Cheung, William Hansen, R. D. Hooton, Andreas Luttge, Jeffrey J. Thomas
Hydration of portland cement is the cornerstone of the process responsible for microstructure development in concrete and ultimately controls the kinetics of all materials properties that make concrete such a useful product for society (properties such as

Versus: A Framework for General Content-Based Comparisons

December 5, 2011

Richard Ayers, Shira Danker, Rick Mislan
… found in mobile devices today, equal or exceed that of the computing power present in desktop computers of less than a …

Current Issues in Optical Diffraction Theory

October 16, 2008
Author(s)
Klaus Mielenz
This paper focuses on unresolved or poorly documented issues pertaining to Fresnel's diffraction theory and its various modifications. In Sec. 2 of the paper it is pointed out that all thermal sources used in practice are finite in size, so that the

Simulated SEM Images for Resolution Measurement

July 30, 2008
Author(s)
Petr Cizmar, Andras Vladar, Bin Ming, Michael T. Postek
Resolution is a key performance metric, which often defines the quality of a scanning electron microscope (SEM). Traditionally, there is the subjective measurement of the distance between two points on special ''resolution'' samples and there are several

Development of an Experimental Database and Kinetic Models for Surrogate Diesel Fuels

April 16, 2007
Author(s)
J T. Ferrell, N Cernansky, F L. Dryer, Daniel G. Friend, C A. Hergart, C K. Law, R M. McDavid, Christian Mueller, A K. Patel, Heinz Pitsch
Computational fluid dynamic (CFD) simulations that include realistic combustion/emissions chemistry hold the promise of significantly shortening the development time for advanced, high efficiency, low emission engines. However, significant challenges must

Flame Extinguishment in a Cup-Burner Apparatus

March 1, 2005
Author(s)
F Takahashi, Gregory T. Linteris, V Katta
Unsteady extinguishment phenomena of laminar methane-air co-flow diffusion flames formed in a cup-burner apparatus at normal earth gravity have been studied experimentally and computationally. A gaseous fire-extinguishing agent (CO 2, N 2, He, Ar, or CF 3H

Extinguishment of Cup-Burner Flames in Low Gravity

January 1, 2005
Author(s)
F Takahashi, Gregory T. Linteris, V Katta
The effects of oxidizer stream velocity and oxygen concentration, as well as gravity and pressure, on the extinguishment limits of laminar co-flow diffusion flames of methane, formed in a cup-burner apparatus, have been studied experimentally and

March 1, 1992
Author(s)
Thomas R. Kramer
STEP is the emerging international Standard for the Exchange of Product Model Data being developed under the auspices of the International Organization for Standardization (ISO). PDES is the acronym for Product Data Exchange using STEP. It is the U. S

Integration of Life Cycle Inventories Incorporating Manufacturing Unit Processes

August 31, 2011
Author(s)
Mark B. Campanelli, Jonatan K. Berglund, Sudarsan Rachuri
Sustainable manufacturing (SM) concerns the manufacture of products with regard to environmental, social, and economic impacts over the entire life cycle. With a primary focus on environmental concerns, life cycle assessment (LCA) can support SM practices
