A Bell Inequality for a Class of Multilocal Ring Networks

Author(s)
Michael R. Frey
Quantum networks with independent sources of entanglement (hidden variables) and nodes that execute joint quantum measurements can create strong quantum correlations spanning the breadth of the network. Understanding of these correlations has to the

A Strategy for Testing Hardware Write Block Devices

Author(s)
James R. Lyle
There is a critical need in the law enforcement community to ensure the reliability of computer forensic tools. A capability is required to ensure that forensic software tools consistently produce accurate and objective test results. The goal of the

Advanced Digital Image Archival System Using MPEG Technologies

Author(s)
Wo L. Chang
Digital information and records are vital to the human race regardless of the nationalities and eras in which they were produced. Digital image contents are produced at a rapid pace from cultural heritages via digitalization, scientific and experimental

An Analysis Framework and Additive Software Analysis

Author(s)
Paul E. Black
We present a framework for software assurance, in addition to an additive software analysis approach. Both have the potential to dramatically reduce software vulnerabilities within the next seven years. The framework (1) aggregates tool outputs, (2) allows

An Automated Acoustic System to Monitor and Classify Birds

Author(s)
C. Kwan, K C. Ho, G. Mei, Y Li, Z. Ren, R. Xu, Y. Zhang, R. Lao, M. Stevenson, Vincent M. Stanford, C. Rochet
This paper presents a novel bird monitoring and recognition system in noisy environments. The project objective is to avoid bird strikes to aircraft. First, a cost effective microphone dish concept (microphone array with many concentric rings) is presented

Anomalous damping of excitations in a collisionless dipolar Bose gas

Author(s)
Stefan Natu, Ryan M. Wilson
We present a theory for the Landau damping of low energy quasi-particles in a collisionless, quasi- 2D dipolar Bose gas and produce expressions for the damping rate in uniform and non-uniform systems. In the homogeneous system, we find that the nature of

Buckling of steel gusset plates

Author(s)
Chiara Crosti, Dat Duthinh
As a result of the structural failure of the I-35W bridge in Minneapolis in 2007, FHWA issued guidelines for the load rating of gusset plates and recommended that the capacity of these plates on non-load-path-redundant steel truss bridges be verified. The

Characterizing and Fractionating Native Cellulose Nanofibers

Author(s)
Iulia A. Sacui, Jeffrey W. Gilman
Cellulose nanofibers have good elastic modulus properties and can be used as nano-reinforcements in polymer composites. Native cellulose nanofibers from wood, Tunicate, and bacteria (Acetobacter xylium) were characterized by atomic force microscopy (AFM)

Coercivities Above 10 kOe in CoPd Superlattices

Author(s)
William F. Egelhoff Jr., Cedric J. Powell, L Gan, P J. Chen, H Ettedgui, D Tirosh, Robert D. McMichael, Mark D. Stiles, J Mallett, Alexander J. Shapiro, John E. Bonevich, J H. Judy, Erik B. Svedberg, A. E. Berkowitz
We have achieved excellent grain isolation in CoPd superlattices by using 10 nm Au as both an underlayer and an overlayer and diffusing Au into the grain boundaries by annealing for {approximately equal to} 30 min. at 300 degrees C. The grain isolation

Coexistence calculation using the Isothermal-Isochoric Integration Method

Author(s)
Seyed M. Razavi, Richard A. Messerly, J. R. Elliott
In this work, an isothermal-isochoric integration (ITIC) method is proposed and tested as a viable method for vapor pressure calculation by molecular simulation. Several tests were carried out to validate the method which resulted in less than 1 %

Colliding Self-Assembly Waves in Organosilane Monolayers

Author(s)
K Efimenko, Ali Ozcam, Jan Genzer, Daniel A. Fischer, Frederick R. Phelan Jr., Jack F. Douglas
Colliding autocatalytic wave-fronts of organosilane (OS) layer self-assembly are generated through the controlled positioning of sources of the volatile OS material at the edges of a silica wafer and through adjustment of the container dimensions in which
