Of Massive Static Analysis Data

June 20, 2013
Author(s)
Aurelien M. Delaitre, Vadim Okun, Elizabeth N. Fong
Static analysis produces large amounts of data. The volume of data allows for new developments in research. Practical observations of the effectiveness of static analysis tools can be derived from that data. The question of tool statistical independence

VULCAN: Vulnerability Assessment Framework for Cloud Computing

June 20, 2013
Author(s)
Patrick Kamongi, Srujan Kotikela, Krishna Kavi, Mahadevan Gomathisankaran, Anoop Singhal
Assessing security of software services on Cloud is complex because the security depends on the vulnerability of infrastructure, platform and the software services. In many systems, the platform or the infrastructure on which the software will actually run

Cellulose Nanomaterials: Nanocomposite Imaging using FRET

June 19, 2013
Author(s)
Jeffrey W. Gilman, Mauro Zammarano, Iulia A. Sacui, Jeremiah Woodcock
Cellulose is the most abundant organic polymer on Earth, found in plants (cotton, hemp, wood), marine animals (Tunicate), algae (Valonia) bacteria (Acetobacter xylium) and even amoeba (Dictyostelium discoideum). Critical features of the structural

Cubic Silsesquioxanes as Tunable High Performance Coating Materials

June 19, 2013
Author(s)
Christopher Soles, Hyun W. Ro, Aaron Forster, Dave J. Krug, Vera Popova, Richard M. Laine
In this manuscript a series of cubic silsequioxane monomers with their eight vertices functionalized with different organic ligands terminated with triethoxysilane groups were acid hydrolyzed, spin cast into thin films, and then vitrified into hard

Just Add Water reproducible singly dispersed silver nanoparticle suspensions

June 19, 2013
Author(s)
Robert I. MacCuspie, Andrew J. Allen, Matthew N. Martin, Vincent A. Hackley
Silver nanoparticles (AgNPs) are of interest due to their antimicrobial attributes, which are derived from their inherent instability and subsequent release of silver ions into solution. At the same time, this instability makes achieving stable long-term

Stratified Sampling for the Ising Model: A Graph-Theoretic Approach

June 19, 2013
Author(s)
Amanda A. Streib, Noah S. Streib, Isabel M. Beichl, Francis Sullivan
We present a new approach to a classical problem in statistical physics: estimating the partition function and other thermodynamic quantities of the ferromagnetic Ising model. Markov chain Monte Carlo methods for this problem have been well-studied

Photon-Number-Resolved Detection of Photon-Subtracted Thermal Light

June 18, 2013
Author(s)
Jingyun Fan, Yanhua (. Zhai, Francisco E. Becerra Chavez, Boris L. Glebov, Adriana E. Lita, Brice R. Calkins, Thomas Gerrits, Sae Woo Nam, Alan L. Migdall
We examine the photon statistics of photon-subtracted thermal light using photonnumberresolving detection. We show the photon-number distribution transforms from a Bose-Einstein distribution to a Poisson distribution as the number of photons subtracted

Distributed Coverage Optimization in a Network of Static and Mobile Sensors

June 17, 2013
Author(s)
Kamran Sayrafian, Hamid Mahboubi, Jalal Habibi, Amir Aghdam
This paper proposes efficient schemes to increase sensing coverage in a network composed of both mobile and static sensors. The proposed deployment techniques properly assign a virtual weight to every point in the sensing field, based on the information

International Comparison of Surface Roughness, APMP.L-K8

June 17, 2013
Author(s)
Andrew Baker, Siew-Leng Tan, Richard Leach, Lena Jung, Seung Yin Wong, Anusorn Tonmueanwai, Kazuya Naoi, Jaewan Kim, Thomas Brian Renegar, K P Chaudhary, Louise Mostert, Mohamed Amer, Sitian Gao, Chin-Lung Tsai, Ngo N. Anh, Augustinus Drijarkara
Surface roughness calibration services of sixteen countries from four metrology regions are compared through measurements of roughness and step height standards. The artefacts circulated include three steps of nominal depths 0.4 μm, 2.4 μm and 10 μm

Properties of Selected Materials at Cryogenic Temperatures

June 17, 2013
Author(s)
Peter E. Bradley, Ray Radebaugh
The design of systems for operation at cryogenic temperatures requires the use of material properties at these low temperatures. The properties at cryogenic temperatures can be much different than the room-temperature values. In addition, some properties

Fermion Mediated Interactions Between Ultracold Bosons

June 16, 2013
Author(s)
Ian B. Spielman, Subhadeep De
We describe a new method for creating spin-dependent long-range interactions between atomic ultra-cold neutral bosons in an optical lattice. In this proposal, the bosonic system is immersed in a spin polarized degenerate Fermi gas. We first show that the

Radio-Frequency and DC Electrical Characterization on a Modular MEMS Mechanical Test Platform for Nanomaterials

June 16, 2013
Author(s)
J. J. Brown, Thomas Mitchell (Mitch) Wallis, Pavel Kabos, Kristine A. Bertness, Norman Sanford, Victor Bright
In order to enable radio frequency (RF) data collection from a micromechanical system designed to strain nanomaterials, a coplanar electrical waveguide has been integrated with an actuated microscale stage. RF (100 MHz to 20 GHz) admittance measurements

A comb-calibrated FMCW LADAR for absolute distance measurements

June 15, 2013
Author(s)
Esther Baumann, Fabrizio R. Giorgetta, Ian R. Coddington, Laura C. Sinclair, Kevin O. Knabe, William C. Swann, Nathan R. Newbury
We present a comb calibrated frequency-modulated continuous wave (FMCW) LADAR system for absolute distance measurements to diffuse or specular surfaces. The FMCW LADAR uses a MEMS-based external cavity laser that is swept quasi-sinusoidally over 1 THz at a
