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
