Configuration of profiling tools for C/C++ applications under 64-bit Linux

March 20, 2013
Author(s)
David W. Flater
Application profiling tools are the instruments used to measure software performance at the function and application levels. Without careful configuration of the tools and the environment, invalid results are readily obtained. The errors may not become

Long-Wavelength Beam Steerer Based on a Micro-Electromechanical Mirror

March 1, 2013
Author(s)
Eyal Gerecht, Anthony B. Kos
Commercially available mirrors for scanning THz beams are too large to allow high-speed THz imaging. There is a need for smaller, more agile pointing apparatus to provide THz images in seconds, not minutes or hours. We have developed a fast THz beam

Advanced Calibration, Adjustment, and Operation of a Density and Sound Speed Analyzer

February 26, 2013
Author(s)
Tara J. Fortin, Arno D. Laesecke, Malte B. Freund, Stephanie L. Outcalt
Benchtop measurement systems have emerged as powerful tools in the ongoing quest for thermophysical property data. We demonstrate that these instruments can yield high quality data if operated in an informed manner. The importance of sample purity

Eddy Current Rail Inspection Using AC Bridge Techniques

February 26, 2013
Author(s)
Andrew D. Koffman, Bryan C. Waltrip, Yicheng Wang
AC bridge techniques commonly used for precision impedance measurements have been adopted to develop an eddy current sensor for rail defect detection. By using two detection coils instead of just one in a conventional sensor, we can balance out the large

Quantitative measurements of glutathione in yeast cell lysate using 1H NMR

February 20, 2013
Author(s)
Steve Y. Rhieu, Aaron A. Urbas, Katrice Lippa, Vytas Reipa
A method for quantifying the level of glutathione (GSH) in yeast cell lysate is described using 1H NMR analysis. For quantification purposes, the 1H resonances corresponding to the Cys βCH2 of GSH were identified as having the fewest overlapping spectral

Effects of fiber gripping methods on the single fiber tensile test: I. Non parametric statistical analysis

February 15, 2013
Author(s)
Jae Hyun Kim, Nathanael A. Heckert, Stefan D. Leigh, Haruki Kobayashi, Walter G. McDonough, Kirk D. Rice, Gale A. Holmes
Single fiber tensile tests using two different gripping methods were carried out on various fiber lengths. One method (the glue-tab grip) consists of mounting a fiber onto a rigid tab as specified in ASTM C1557-03 using an adhesive, while the other (the
