Bi2Te3 and Bi2Te3-xSx FOR THERMOELECTRIC APPLICATIONS

October 15, 2012
Author(s)
Winnie K. Wong-Ng, N D. Lowhorn, Joshua B. Martin, Peter Zavalij, Howard Joress, Qingzhen Huang, Yonggao Y. Yan, Azzam Mansour, Evans L. Thomas, Jihui Yang, Martin L. Green
The increased interest in research and development on thermoelectric materials is partly due to the need for improved efficiency in the global utilization of energy resources. Historically, Bi2Te3 occupies an important position in the thermoelectric

Evaluation of Fault Detection Effectiveness for Combinatorial and Exhaustive Selection of Discretized Test Inputs

June 4, 2012
Author(s)
Carmelo Montanez-Rivera, David R. Kuhn, Mary C. Brady, Richard M. Rivello, Jenise Reyes Rodriguez, Michael K. Powers
Testing components of web browsers and other graphical interface software can be extremely expensive because of the need for human review of screen appearance and interactive behavior. Combinatorial testing has been advocated as a method that provides

CfA4: 93 Type Ia Supernova Light Curves from the CfA

May 17, 2012
Author(s)
Malcolm Hicken, Peter Challis, Robert Kirshner, Claire E. Cramer, Armin Rest, W. M. Wood-Vasey, Gaspar Bakos, Perry Berlind, Warren R. Brown, Nelson Caldwell, Michael Calkins, Maria Contreras, Gil Esquerdo, Mark Everett, Emilio Falco, Ted Groner, Matthew J. Holman, Robert Hutchison, Michael Pahre, Wayne Peters, Benjamin Ripman, Timothy Spahr, Andrew Szentgyorgyi, Manuel A. Torres, Amali Vaz
We present multi-band photometry of 93 type-Ia supernovae (SN Ia). Data was acquired with the Keplercam instrument between 2006 and 2011 at the F. L. Whipple Observatory of the Harvard-Smithsonian Center for Astrophysics (CfA). Our natural system SN

Spectroscopic Measurement of the Vapour Pressure of Ice

January 1, 2012
Author(s)
Katarzyna E. Bielska, Daniel K. Havey, Gregory E. Scace, D Lisak, Joseph T. Hodges
We present a laser absorption technique to measure the vapor pressure of ice. This method is referenced to the triple point state of water and uses frequency-stabilized cavity ring-down spec- troscopy to probe four rotation-vibration transitions of H16 2 O

CMSD: A Model Supporting Manufacturing and Simulation Application Integration

September 20, 2010
Author(s)
Frank H. Riddick, Yung-Tsun T. Lee
Standard representations for key manufacturing entities could help reduce the costs associated with simulation model construction and data exchange between simulation and other software applications. This change would make the use of simulation technology

A More General Type A Evaluation

September 9, 2010
Author(s)
Ruediger Kessel, Raghu N. Kacker, Klaus-Dieter Sommer
The evaluation of uncertainty according to the Guide to the Expression of Uncertainty in measurement is the internationally agreed procedure to evaluate the complete result statement in measurement including measurement uncertainty. It distinguishes two

Dynamic 6DOF Metrology for Evaluating a Visual Servoing

August 21, 2008
Author(s)
Tommy Chang, Tsai H. Hong, Michael O. Shneier, G Holguin, J Park, Roger D. Eastman
In this paper we demonstrate the use of a dynamic, six-degree-of-freedom (6DOF) laser tracker to empirically evaluate the performance of a real-time visual servoing implementation, with the objective of establishing a general method for evaluating real

Design, Fabrication, and Characterization of High-Performance Silicon Nanowire Transistors

August 1, 2008
Author(s)
Qiliang Li, Xiaoxiao Zhu, Yang Yang, D. E. Ioannou, Hao Xiong, John S. Suehle, Curt A. Richter
We report the fabrication and characterization of double-gated Si nanowire field effect transistors with excellent current-voltage characteristics, low subthreshold slope 85 mV/dec and high on/off current ratio 10^6. The Si nanowire devices are fabricated

A Weighted GCV Method for Lanczos Hybrid Regularization

January 15, 2008
Author(s)
Julianne Chung, James G. Nagy, Dianne M. O'Leary
Lanczos-hybrid regularization methods have been proposed as effective approaches for solving large-scale ill-posed inverse problems. Lanczos methods restrict the solution to lie in a Krylov subspace, but they are hindered by semi-convergence behavior, in
