SIM time scales

October 27, 2010
Author(s)
Michael A. Lombardi, J. Mauricio Lopez-Romero, Nelida Diaz-Munoz
This paper presents an analysis of the performance of some of the time scales generated in the Sistema Interamericano de Metrologia (SIM) region. We emphasize the generation of the first international time scale in near real time, the SIM Time scale (SIMT)

Intrinsic defects in perpendicularly magnetized multilayer thin films and nanostructures

October 26, 2010
Author(s)
Justin M. Shaw, Miles Olsen, June W. Lau, Michael L. Schneider, Thomas J. Silva, Olav Hellwig, Elizabeth Dobisz, Bruce D. Terris
Intrinsic magnetic defects in perpendicularly magnetized nanostructures reduce the predictability of device and developing recording technologies. In addition to a distribution of local anisotropy fields, we show that such defects also exhibit variations

Scaling studies with the dual crystal spectrometer at the OMEGA-EP laser facility

October 26, 2010
Author(s)
Lawrence T. Hudson, C.I Szabo, J. Workman, K. Flippo, Uri Feldman, Albert Henins
The dual crystal spectrometer (DCS) is an approved diagnostic at the OMEGA and the OMEGA-EP laser facilities for the measurement of high energy x-rays in the 11 90 keV energy range, e.g., for verification of the x-ray spectrum of backlighter targets of

An IEEE 1588 Time Synchronization Testbed for Assessing Power Distribution Requirements

October 25, 2010
Author(s)
Julien M. Amelot, Clement Vasseur, Jeffrey Fletcher, Dhananjay Anand, Ya-Shian Li-Baboud, James Moyne
Wide-area monitoring applications for power distribution rely on accurate global time synchronization. Furthermore, there is interest in replacing current time synchronization methods such as IRIG, with distributed time synchronization protocols that

Assessing Library Performance Using the Baldrige Criteria for Performance Excellence: Framework and Systems that Focus on Results and Ensure Sustainability

October 25, 2010
Author(s)
Susan L. Makar, Mary D. Coraggio, Mylene S. Ouimette, Barbara P. Silcox
Successful management of organizational performance requires interconnected systems that link goals and strategies with customer and stakeholder requirements, key processes, and measures. This systems-oriented approach ensures consistency across plans

Maintainers Manual for Version 2.2.1 of the NIST DMIS Test Suite

October 25, 2010
Author(s)
Thomas R. Kramer, John A. Horst
This manual is a maintainers manual for the NIST DMIS Test Suite, version 2.2.1. DMIS (Dimensional Measuring Interface Standard) is a language for writing programs for coordinate measuring machines and other dimensional measurement equipment. The manual is

Performance Assessment of Face Recognition Using Super-Resolution

October 25, 2010
Author(s)
Shuowen Hu, Robert Maschal, S. S. Young, Tsai H. Hong, P. Jonathon Phillips
Recognition rate of face recognition algorithms is dependent on the resolution of the imagery, specifically the number of pixels contained within the face. Using a sequence of frames from low-resolution videos, super-resolution reconstruction can form a

Fast high-resolution frequency agile spectroscopy of laser sources

October 24, 2010
Author(s)
Fabrizio R. Giorgetta, Ian R. Coddington, Esther Baumann, William C. Swann, Nathan R. Newbury
Time-resolved, high-accuracy and high-resolution spectroscopy of frequency-agile cw lasers is critical to realizing their full potential for sensing, but is not possible with conventional spectroscopy methods. We demonstrate a dual comb-based spectrometer

Detection and Characterization of Selenoproteins by Tandem Mass Spectrometry Assisted by Laser Ablation Inductively Coupled Plasma Mass Spectrometry: Application to Human Plasma Selenoproteins

October 22, 2010
Author(s)
Guillaume Ballihaut, Lisa Kilpatrick, Eric L. Kilpatrick, William Davis
There has been an on-going effort and long term goal to accurately assess selenium status and selenium nutritional requirement in humans through the quantification of human plasma selenoprotein P (SelP) and glutathione peroxidase 3 (GPx3). To achieve this

Intrusion Detection and Prevention Systems

October 22, 2010
Author(s)
Karen A. Scarfone, Peter M. Mell
Intrusion detection is the process of monitoring the events occurring in a computer system or network and analyzing them for signs of possible incidents. An intrusion detection and prevention system (IDPS) is software that automates the intrusion detection

Structural Analysis of Soft Multicomponent Nanoparticle Clusters Using Electrospray Differential Mobility Analysis with Transmission Electron Microscopy

October 22, 2010
Author(s)
Leonard F. Pease , Jeremy Feldblyum, Silvia H. DePaoli Lacaerda, Rajesekhar Anumolu, Peter Yim, Matthew L. Clarke, Hyeong G. Kang, Jeeseong C. Hwang
Rapid and quantitative techniques are essential to analyze soft multicomponent nanoparticle clusters. Here we combine electrospray differential mobility analysis (ES-DMA), which measures the size of the entire cluster, with transmission electron microscopy

The evolving optical frequency comb

October 22, 2010
Author(s)
Scott A. Diddams
Much as natural historians search for the first roots of our human race, curiosity drives the laser scientist to pursue the roots of his or her own field. This is especially the case in this year where our community celebrates the 50th anniversary of the
