Spent Fuel Transportation Package Response to the MacArthur Maze Fire Scenario

October 2, 2015
Author(s)
Kevin B. McGrattan, Harold Adkins
The NRC has established requirements that are the design bases for packaging and transportation of spent nuclear fuel assemblies under normal conditions of transport (NCT) and for hypothetical accident conditions (HAC). Real-world accidents of greater

Assessment of Water Vapor Diffusion in Firefighters Protective Clothing

October 1, 2015
Author(s)
Shonali Nazare, Christopher W. Meyer, Daniel M. Madrzykowski
Structural firefighters often encounter hot and humid environments during interior firefighting. The water vapor transfer to and from the skin has great influence on thermo-physiological comfort of the firefigher. Quantitative information on water vapor

Broadly tunable, low timing jitter, high repetition rate optoelectronic comb generator

October 1, 2015
Author(s)
Franklyn J. Quinlan, A. J. Metcalf, Tara M. Fortier, Scott A. Diddams, Andrew M. Weiner
We investigate the low timing jitter properties of a tunable single-pass optoelectronic frequency comb generator. The scheme is flexible in that both the repetition rate and the center frequency can be continuously tuned. When operated at 10 GHz comb

CCQM Pilot Study P-140; Quantitative Surface Analysis of Multi-Element Alloy Films

October 1, 2015
Author(s)
David S. Simons, Christopher W. Szakal, William A. Osborn, Kyung Joong Kim
A pilot study for the quantitative surface analysis of multi-element alloy films has been performed by the Surface Analysis Working Group (SAWG) of the Consultative Committee for Amount of Substance (CCQM). The aim of this pilot study is to ensure the

Electrodeposition of gold to conformally fill high-aspect-ratio nanometric silicon grating trenches: a comparison of pulsed and direct current protocols

October 1, 2015
Author(s)
sami Znati, N Chedid, Houxun Miao, Lei Chen, Han Wen, Eric E. Bennett
Filling high-aspect-ratio trenches with gold is a frequent requirement in the fabrication of X-ray optics as well as micro-electronic components and other fabrication processes. Conformal electrodeposition of gold in sub-micron-width silicon trenches with

Fiber Bragg Grating Based Thermometry

October 1, 2015
Author(s)
Zeeshan Ahmed, Bernard J. Filla, William F. Guthrie, John S. Quintavalle
In recent years there has been considerable interest in developing photonic temperature sensors such as the Fiber Bragg gratings (FBG) as an alternative to resistance thermometry. In this study we examine the thermal response of FBGs over the temperature

Intelligence Level Performance Standards Research for Autonomous Vehicles

October 1, 2015
Author(s)
Roger V. Bostelman, Tsai H. Hong, Elena R. Messina
U.S. and European safety standards have evolved to protect workers near Automated Guided Vehicles (AGV's). However, only recently performance standards have begun development for AGV's and mobile robots. Lessons can be learned for developing such a

Low noise kinetic inductance traveling-wave amplifier using three-wave mixing

October 1, 2015
Author(s)
Michael R. Vissers, Robert P. Erickson, Leila R. Vale, Xian Wu, Gene C. Hilton, David P. Pappas
We have fabricated a wide-bandwidth, high dynamic range, low noise cryogenic amplifier based on a superconducting kinetic inductance traveling-wave device. The device was made from NbTiN and consisted of a long, coplanar waveguide on a silicon chip. By

Peer-to-Peer Urban Channel Characteristics for Two Public-Safety Frequency Bands

October 1, 2015
Author(s)
Catherine A. Remley, David W. Matolak, Camillo A. Gentile, Christopher L. Holloway, Qiong Wu, Qian Zhang
We report on ground-based wireless channel characteristics for an urban environment in two public safety bands. Results are based upon measurements taken in Denver in June 2009. The public safety bands we investigated are the 700 MHz and 4.9 GHz bands

Research highlights: Probing adsorbed organic coatings on nanoparticle surfaces

October 1, 2015
Author(s)
Stacey M. Louie, John M. Pettibone
Organic coatings adsorbed at a nanoparticle surface, together with the system properties, change the physicochemical properties of the nanoparticle, thereby possibly modifying its behavior and interactions with its surroundings. A detailed understanding of

Self-powered p-NiO/n-ZnO heterojunction ultraviolet photodetectors fabricated on plastic substrates

October 1, 2015
Author(s)
Ratan K. Debnath, MD R. Hasan, Ting Xie, Sara C. Barron, Guannan Liu, Nhan V. Nguyen, Abhishek Motayed, M V. Rao
A self-powered ultraviolet (UV) photodetector (PD) based on p-NiO and n-ZnO was fabricated using low-temperature sputtering technique on indium doped tin oxide (ITO) coated plastic polyethylene terephthalate (PET) substrates. The fabricated devices showed

Spreading alerts quietly and the subgroup escape problem

October 1, 2015
Author(s)
J. Aspnes, Z. Diamadi, A. Yampolskiy, K. Gjosteen, Rene Peralta
We introduce a new cryptographic primitive called a blind coupon mechanism (BCM). In effect, a BCM is an authenticated bit commitment scheme, which is AND-homomorphic. We show that a BCM has natural and important applications. In particular, we use it to
