Thermo-elastic induced phase noise in the LISA Pathfinder spacecraft

January 25, 2015
Author(s)
Ferran Gibert, Miquel Nofrarias, Nico Karnesis, Lluis Gesa, Victor Martin, Ignacio Mateos, Alberto Lobo, Reinhold Flatscher, Domenico Gerardi, Johannes Burkhardt, Ruediger Gerndt, David I. Robertson, Henry Ward, Paul McNamara, Felipe Guzman, Martin Hewitson, Ingo Diepholz, Jens Reiche, Gerhard Heinzel, Karsten Danzmann
During the on-station thermal test campaign of the LISA Pathfinder, the diagnostics subsystem was tested in nearly space conditions for the first time after integration in the satellite. The results showed the compliance of the temperature measurement

HVACR Editorial for IAQ 2013 Special Issue

January 23, 2015
Author(s)
Hal Levin, Steven Emmerich
The papers in this issue were selected from presentations made at the ASHRAE IAQ 2013: Environmental Health in Low Energy Buildings conference held in Vancouver Canada in October 2013. The conference was held specifically to review the state of knowledge

Quasielastic Neutron Scattering Study of POSS Ligand Dynamics

January 23, 2015
Author(s)
Niina Jalarvo, Madhu Sudan Tyagi, Michael K. Crawford
Polyoligosilsesquioxanes are molecules having cage-like structures composed of silicon and oxygen. These molecules can have a wide variety of functional ligands attached to them. Depending on the nature of the ligand, interesting properties and application

Public Safety Mobile Application Security Requirements Workshop Summary

January 22, 2015
Author(s)
Michael Ogata, Barbara Guttman, Nelson Hastings
This document captures the input received from the half-day workshop titled "Public Safety Mobile Application Security Requirements" organized by the Association of Public-Safety Communications Officials (APCO) International, in cooperation with FirstNet

Spectral Correlation Measurements at the Hong-Ou-Mandel Interference Dip

January 22, 2015
Author(s)
Thomas Gerrits, Francesco Marsili, Varun B. Verma, Lynden K. Shalm, Jeffrey A. Stern, Matthew Shaw, Richard P. Mirin, Sae Woo Nam
We present an efficient tool capable of measuring the spectral correlations between photons emerging from a Hong-Ou-Mandel interference configuration. We show that the Hong-Ou-Mandel interference visibility decreases as the photons’ frequency spread is

Workshop Summary: Materials Genome Initiative: Materials Data

January 22, 2015
Author(s)
James A. Warren
A key objective for the Materials Genome Initiative (MGI) is access to digital materials data. Access may be for an individual, a team, company, or an entire community of interest. There are several challenges to providing access to digital materials data

A determination of the local acceleration of gravity for the NIST-4 watt balance

January 21, 2015
Author(s)
David B. Newell, Eric J. Leaman, Darine El Haddad, Frank C. Seifert, Leon S. Chao, Yusi A. Cao, Jon R. Pratt, Stephan Schlamminger
A new watt balance is being constructed at the National Institute of Standards and Technology in preparation for the redefinition of the International System of Units and the realization of mass through an exact value of the Planck constant. The total

Effect of Installation Faults on Air-to-Air Heat Pump Performance

January 20, 2015
Author(s)
Piotr A. Domanski
Numerous studies and surveys indicate that typically-installed HVAC equipment operate inefficiently and waste considerable energy due to different installation errors (faults) such as improper refrigerant charge, incorrect airflow, oversized equipment

Pulse-to-pulse jitter measurement by photon correlation in high-ss lasers

January 20, 2015
Author(s)
Armand Lebreton, Abram Izo, Remy Braive, Nadia Belabas, Isabelle Sagnes, Francesco F. Marsili, Varun Verma, Sae Woo Nam, Thomas Gerrits, Isabelle Robert-Philip, Martin Stevens, Alexios Beveratos
The turn-on delay jitter in pulsed lasers in which a large fraction (β) of spontaneous emission is channeled into the lasing mode is measured by use of a photon correlation technique. This jitter is found to significantly increase with β, reaching values of

Phase Diagram of the Relaxor Ferroelectric (1-x)Pb(Mg 1/3 Nb 2/3 )O 3-x PbTiO 3 Revisted: A neutron Powder Diffraction Study of the Relaxor Skin Effect

January 19, 2015
Author(s)
Daniel Phelan, Efrain E. Rodriguez, J Gao, Y Bing, Z.-G. Ye, Qingzhen Huang, Jinsheng Wen, Guangyong Xu, C. Stock, M Matsuura, Peter M. Gehring
We revisit the phase diagram of the relaxor ferroelectric PMN-xPT using neutron powder diffraction to test suggestions that residual oxygen vacancies and/or strain affect the ground state crystal structure. Powdered samples of PMN-xPT were prepared with

Solution-processed high-efficiency p-NiO/n-ZnO heterojunction photodetector

January 19, 2015
Author(s)
Ratan K. Debnath, Ting Xie, Baomei Wen, Wei Li, Abhishek Motayed, Nhan V. Nguyen
This paper presents a high efficiency heterojunction p-NiO/n-ZnO thin film ultraviolent (UV) photodetector fabricated on conductive glass substrates. The devices are fabricated by using a simple spin-coating layer-by-layer method from precursor solutions

How Random is Your RNG?

January 18, 2015
Author(s)
Meltem Sonmez Turan, John M. Kelsey, Kerry A. McKay
Cryptographic primitives need random numbers to protect your data. Random numbers are used for generating secret keys, nonces, random paddings, initialization vectors, salts, etc. Deterministic pseudorandom number generators are useful, but they still need

Open Calphad - a free thermodynamic software

January 17, 2015
Author(s)
Bo Sundman, Ursula R. Kattner, Mauro Palumbo, Suzana G. Fries
The use of thermodynamics in many applications in material science like simulation of phase trans- formation suffers from the lack of high quality open source software for calculations of multicomponent systems. The goal of the Open Calphad (OC) software

Pyrolysis Smoke Generated Under Low-Gravity Conditions

January 17, 2015
Author(s)
Jiann C. Yang, Thomas G. Cleary, George W. Mulholland, D L. Urban, Gary A. Ruff, Zeng-guang Yuan, Marit Meyer, Victoria Bryg
A series of smoke experiments were carried out in the Microgravity Science Glovebox on the International Space Station (ISS) Facility to assess the impact of low-gravity conditions on the size distribution and structure of the smoke aerosol. This
