Using and creating databases for data analysis in laser spectroscopy

January 1, 2014
Author(s)
Alexander Kramida
A brief review of existing atomic spectroscopy databases is given with an emphasis on databases relevant to laser spectroscopy research. Key data elements in these databases are described. A strategy of building a specialized relational database for laser

December 31, 2013
Author(s)
Rafa Marin-Lopez, Fernando Bernal-Hidalgo, Subir Das, Lidong Chen, Yoshihiro Ohba
When enabling handover between different radio interfaces (e.g., handover from 3G to Wi-Fi), reducing network access authentication latency and securing handover related signaling messages are major challenging problems, amongst many others. The IEEE 802

Chapter 3 Evaluation of Atmospheric Loss Processes

December 31, 2013
Author(s)
Vladimir L. Orkin, James B. Burkholder, Wahid Mellouki, Eric L. Fleming, Christian George, Charles H. Jackman, Timothy J. Wallington , Michael J. Kurylo , Dwayne E. Heard, William H. Swartz
Hydroxyl radical (OH), electronically excited atomic oxygen (O(1D)), and atomic chlorine (Cl) reaction rate coefficient data were evaluated and the estimated uncertainties in the recommended parameters reduced, in general, from those currently recommended

Constrained Hierarchical Control of a Diffusion Equation

December 31, 2013
Author(s)
Anthony J. Kearsley
In this paper, we consider the approximate pointwise control of a linear parabolic system with multiple targets. The location of the pointwise controls are constrained and we assume hierarchy among the objectives, Optimality conditions are derived for a

Mapping Return Values of Extreme Wind Speeds

December 31, 2013
Author(s)
Adam L. Pintar
Structures subjected to wind loads must be designed to perform adequately from the points of view of stress and serviceability. Wind loading specified for design is based in part on the wind speeds affecting the site of interest. A particular quantity of

Nonlinear Vibrational Spectrometry

December 31, 2013
Author(s)
Lee J. Richter
Second order nonlinear spectroscopies such as sum frequency generation (SFG) are intrinsically interface sensitive and enable sub monolayer sensitivity to be achieved at buried, optically accessible interfaces. Vibrationally-resonant SFG allows bond

ThermoData Engine (TDE) Version 8.0 (Pure Compounds, Binary Mixtures, Ternary Mixtures, and Chemical Reactions); NIST Standard Reference Database 103b

December 31, 2013
Author(s)
Michael D. Frenkel, Robert D. Chirico, Vladimir Diky, Kenneth Kroenlein, Chris Muzny, Andrei F. Kazakov, Joe W. Magee, Ilmutdin M. Abdulagatov, Eric Lemmon
The ThermoData Engine is a software expert systems implementing the concept of dynamic data evaluation. This new release includes four important new features. (1) Implementation of the Peng-Robinson EOS for mixtures. (2) Evaluation of ideal-gas entropies

Correlation of rocket propulsion fuel properties with chemical composition using comprehensive two-dimensional gas chromatography with time-of-flight mass spectrometry followed by partial least squares regression analysis

December 30, 2013
Author(s)
Thomas J. Bruno, Benjamin Kehimkar, Jamin C. Hoggard, Luke C. Marney, M. C. Billingsley, C. G. Fraga, R. E. Synovec
There is an increased need to more fully assess and control the composition of kerosene-based rocket propulsion fuels such as RP-1. In particular, it is critical to make better quantitative connections among the following three attributes: fuel performance

The Importance of Dosimetry Standardization in Radiobiology

December 30, 2013
Author(s)
Marc F. Desrosiers, Larry A. DeWerd, James Deye, Patricia Lindsay, Mark K. Murphy, Michael G. Mitch, Francesca Macchiarini, Strahinja Stojadinovic, Helen Stone
Radiation dose is central too much of radiobiological research. Precision and accuracy of dose measurements and reporting of the measurement details should be sufficient to allow the work to be interpreted and repeated and to allow valid comparisons to be

Thermal Conductivity of Monolayer MoS2 Obtained from Temperature-Dependent Raman Spectroscopy

December 30, 2013
Author(s)
Rusen Yan, Jeffrey R. Simpson, Simone Bertolazzi, Jacopo Brivio, Michael Watson, Xufei Wu, Andras Kis, Tengfei Luo, Angela R. Hight Walker, Huili G. Xing
Atomically thin molybdenum disulphide (MoS2) is emerging as a potential alternative to graphene due to presence of bandgap, which is particularly advantageous to optoelectronic applications. The temperature-dependent Raman spectra of exfoliated monolayer

Intertwining of Frustration with Magneto-Elastic Coupling in the Multiferroic LuMnO 3

December 25, 2013
Author(s)
Shin-ichiro Yano, Despina Louca, Songxue Chi, Masaaki Matsuda, Yiming Qiu, John R. Copley, Sang-Wook Cheong
Residual magnetic frustration in the multiferroic LuMNO 3 may be key towards understanding magneto-elastic coupling in hexagonal manganites. Critical magnetic scattering present well above the magnetic ordering temperature Τ N persists below, as observed

Statistical Sampling of Carbon Nanotube Populations by Thermogravimetric Analysis

December 25, 2013
Author(s)
Elisabeth Mansfield, Aparna Kar, Chih-Ming Wang, Ann C. Chiaramonti Debay
Carbon nanotubes are one of the most promising nanomaterials on the market, with applications in electronics devices, sensing, batteries, composites and medical communities. Strict control of the carbon nanotube chemistry and properties is necessary as the

Developmental validation of the PowerPlex 21 System.

December 24, 2013
Author(s)
Carolyn R. Steffen, Martin G. Ensenberger, Robert S. McLaren, Cynthia J. Sprecher, Douglas R. Storts
The PowerPlex(®) 21 System is a STR multiplex that has been optimized for casework samples while still being capable of database workflows including direct amplification. The loci included in the multiplex offer increasing overlap with core loci used in

Fatigue crack growth rates of API X70 pipeline steel in a pressurized hydrogen gas environment

December 21, 2013
Author(s)
Elizabeth S. Drexler, Andrew J. Slifka, Robert L. Amaro, Nicholas Barbosa, Damian S. Lauria, Louis E. Hayden, Douglas G. Stalheim
Hydrogen is known to have a deleterious effect on metal, but pipelines will still be the most cost- effective means of transporting hydrogen gas and sour gas. Rather, it is the codes and standards, such as ASME B31.12, that will guide the design of

A Simulated Sensor-based Approach for Kit Building Applications
