Saeed Khan, Bryce Primavera, Jeff Chiles, Adam McCaughan, Sonia Buckley, Alexander Tait, Adriana Lita, John Biesecker, Anna Fox, David Olaya, Richard Mirin, Sae Woo Nam, Jeff Shainline
Superconducting optoelectronic hardware is being explored as a path towards artificial spiking neural networks with unprecedented scales of complexity and computational ability. Such hardware combines integrated-photonic components for few-photon, light

Quantitative Evaluation of Footwear Evidence: Initial Workflow for an End-to-End System

November 23, 2021
Author(s)
Gautham Venkatasubramanian, Vighnesh Hegde, Steven Lund, Hariharan K. Iyer, Martin Herman
In the U.S., footwear examiners make decisions about the sources of crime scene shoe impressions using subjective criteria. This has raised questions about the accuracy, repeatability, reproducibility, and scientific validity of footwear examinations

Performance of Reservoir Discretizations in Quantum Transport Simulations

September 29, 2021
Author(s)
Justin E. Elenewski, Gabriela Wojtowicz, Marek Rams, Michael P. Zwolak
Quantum transport simulations require a level of discretization, often achieved through an explicit representation of the electronic reservoirs. These representations should converge to the same continuum limit, though there is a trade-off between a given

Deterministic Move Lists for Federal Incumbent Protection in the CBRS Band

October 13, 2020
Author(s)
Michael R. Souryal, Thao T. Nguyen
The 3.5 GHz citizens broadband radio service (CBRS) band in the U.S. is a key portion of mid- band spectrum shared between commercial operators and existing federal and non-federal incumbents in the band. To protect the federal incumbents from harmful

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

Hashing Techniques for Mobile Device Forensics

June 15, 2009
Author(s)
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
