Tailored State Preparation for Solid State Quantum Memory

May 16, 2010
Author(s)
Elizabeth A. Goldschmidt, Sergey V. Polyakov, Sarah E. Beavan, Jingyun Fan, Alan L. Migdall
We use spectral hole burning in Pr3+:Y2SiO5 in order to prepare spectral distributions of ions optimized for using such a material as a quantum memory for photon states. Our spectral hole-burning implementations include preparing an ensemble of ions to be

Atomistic simulation of hillock growth

May 15, 2010
Author(s)
Timofey Frolov, William J. Boettinger, Yuri Mishin
The goal of this paper is to explore mechanisms of hillock and whisker growth in stressed poly-crystalline films by molecular dynamics simulations. Our stress-free model consists of three grains and a triple line aligned perpendicular to a free surface

The Impact of Long-term Memory Effects on Diode Power Probes

May 15, 2010
Author(s)
Catherine A. Remley, Hugo Gomes, Alejandro Testera, Nuno B. Carvalho, Monica Barciela
This paper presents an analysis of long term memory effects on power measurements using diode power probes. It will be shown that a power probe calibrated with a single-tone sinusoidal excitation can provide erroneous values when used with modulated

An Other-Race Effect for Face Recognition Algorithms

May 13, 2010
Author(s)
P J. Phillips, Alice J. O'Toole, Abhijit Narvekar, Fang Jiang, Julianne Ayadd
Psychology research has shown that human face recognition is more accurate for faces of one�s own race than for faces of other races. In recent years, interest in accurate computer-based face recognition systems has spurred the development of these systems

Electrodeposition of Metastable Au-Ni Alloys

May 13, 2010
Author(s)
Gery R. Stafford, E. Rouya, Ugo Bertocci, J. J. Mallett, R. Schad, M. R. Begley, R. G. Kelly, M. Reed, G. Zangari
The electrodeposition of Au-Ni alloys from near neutral, sulfite-based electrolytes derived from a commercial bath for soft gold plating is investigated. Alloy compositions ranging from 0 to 90 at% Ni were obtained by varying the deposition potential, with

A Virtual Machining Model for Sustainability Analysis

May 12, 2010
Author(s)
Guodong Shao, Deogratias Kibira, Kevin W. Lyons
Sustainability has become a very significant research topic since it impacts many different manufacturing industries. The adoption of sustainable manufacturing practices and technologies offers industry a cost effective route to improve economic

Impact of Energy Measurements in Machining Operations

May 12, 2010
Author(s)
Minna S. Lanz, Mahesh Mani, Swee K. Leong, Kevin W. Lyons, Ari Ranta, Kimmo Ikkala, Nils Bengtsson
OOver the past years, institutions in general are increasingly interested and involved in sustainability and social responsibility. In addition, social and political pressures have led to the creation of new regulations and policies that support new

Predicting the In-Service Performance of Materials Exposed to Outdoor Weathering

May 12, 2010
Author(s)
Christopher C. White, Kar T. Tan, Donald L. Hunston
Test methods were developed to duplicate the failure modes that occur to sealants during exposure in structures. The methods used a systematic approach to identify independent and synergistic effects of various aging factors on the durability of sealants

STRUCTURAL RESPONSE OF WTC 7 FLOOR SYSTEMS TO FIRE

May 12, 2010
Author(s)
Therese P. McAllister
The WTC 7 investigation by the National Institute of Standards and Technology (NIST) identified several factors that alone, or in combination, led to fire-induced failures of the floors, and subsequently, total collapse of the 47-story WTC 7 building. A

The NIST Handbook of Mathematical Functions

May 12, 2010
Author(s)
Frank W. Olver, Daniel W. Lozier, Ronald Boisvert, Charles W. Clark
The NIST Handbook of Mathematical Functions supplies validated reference information in 36 chapters on a wide selection of important mathematical functions, covering the properties necessary for their use in scientific applications, together with general

Synthesis and properties of turbostratically disordered,ultrathin WSe2 films

May 11, 2010
Author(s)
Ngoc Nguyen, Polly Berseth, Qiyin Lin, Catalin Chiritescu, D.G. Cahill, Anastassios Mavrokefalos, Li Shi, Paul Zschack, Michael D. Anderson, Ian M. Anderson, David C. Johnson
Turbostratically disordered tungsten diselenide (WSe2) thin films with as few as two c-axis-oriented (basal plane) structural units were synthesized from modulated elemental reactants. By varying the number of elemental W-Se bilayers deposited, the

Test Suite for Building Energy Analysis of Conceptual Spatial Layout

May 11, 2010
Author(s)
Kenway K. Chen, Robert R. Lipman, Mark E. Palmer
This report documents a test suite for validation and conformance testing in support of the interoperability among building design and energy analysis applications. The objectives of this test suite are to: provide to software vendors test cases to

FRVT 2006: Quo Vidas Face Quality

May 10, 2010
Author(s)
P J. Phillips, J. R. Beveridge, Geof H. Givens, Bruce A. Draper, David Bolme, Yui M. Lui
This paper summarizes a study of how three state-of-the-art algorithms from the Face Recognition Vendor Test 2006 (FRVT 2006) are effected by factors related to face images and the people being recognized. The recognition scenario compares highly

Measuring and improving U.S. construction productivity

May 10, 2010
Author(s)
Robert E. Chapman, David T. Butry, Allison L. Huang
Although the construction industry is a major component of the U.S. economy, it has experienced a prolonged period of decline in productivity. Due to the critical lack of measurement methods, however, the magnitude of the productivity problem in the U.S

Shell-dependent Blinking of CdSe-Based Core/Shell Nanocrystals

May 10, 2010
Author(s)
Seung Koo Shin, Bonghwan Chon, Sung Jun Lim, Wonjung Kim, Hyeong G. Kang, Taiha Joo, Jeeseong C. Hwang
Blinking of zinc-blende CdSe-based core/shell nanocrystals are studied as a function of shell materials. CdSe/ZnS, CdSe/ZnSe/ZnS, and CdSe/CdS/ZnS core/shell nanocrystals are prepared by epitaxial growth of two-to-six monolayers (MLs) of shell materials
