Secure Virtual Network Configuration for Virtual Machine (VM) Protection

March 7, 2016
Author(s)
Ramaswamy Chandramouli
Virtual Machines (VMs) are key resources to be protected since they are the compute engines hosting mission-critical applications. Since VMs are end-nodes of a virtual network, the configuration of the virtual network forms an important element in the

Combinatorial Coverage as an Aspect of Test Quality

March 31, 2015
Author(s)
David R. Kuhn, Raghu N. Kacker, Yu Lei
There are relatively few good methods for evaluating test set quality, after ensuring basic requirements traceability. Structural coverage, mutation testing, and related methods can be used if source code is available, but these approaches may entail

Mobile Device Tool Testing

February 19, 2015
Author(s)
Richard Ayers
The Computer Forensic Tool Testing program at NIST has spent several years researching and testing forensic tools capable of acquiring data from the internal memory of mobile devices and Subscriber Identity Modules (SIMs). Test reports provide a foundation

An Efficient Target Monitoring Scheme with Controlled Node Mobility for Sensor Networks

November 3, 2011
Author(s)
Vladimir V. Marbukh, Kamran Sayrafian, Hamid Mahboubi, Ahmadreza Momeni, Amir G. Aghdam
This paper is concerned with target monitoring using a network of collaborative mobile sensors. The objective is to compute (online) the desired sensing and communication radii of sensors as well as their location at each time instant, such that a set of

Optimal Target Tracking Strategy with Controlled Node Mobility in Mobile Sensor Networks

June 30, 2010
Author(s)
Kamran Sayrafian, Vladimir V. Marbukh, Hamid Mahboubi, Ahmadreza Momeni, Amir G. Aghdam
This paper is concerned with target tracking using a network of collaborative sensors. The objective is to compute (online) the desired sensing and communication radii of sensors as well as their location at each time instant, such that a set of prescribed

Dynamical Heterogeneities in the Ising Spin Glass

October 16, 2008
Author(s)
S C. Glotzer, N Jan, T Lookman, A B. MacIsaac, P H. Poole
We investigate the relationship between bulk and local relaxation in the Ising spin glass (in 2 and 3 dimensions) for temperatures above but approaching the glass transition temperature, using Monte Carlo computer simulations. We find that the stretched

Grain Size Distribution in Two Dimensions in the Long Time Limit

July 8, 2008
Author(s)
Geoffrey B. McFadden, C.S. Pande, K.P. Cooper
It is shown that the inclusion of a "noise" term in the growth rate of individual grains leads to a stochastic model that provides a more realistic description of grain growth phenomenon. The resulting Fokker-Planck equation for the grain size distribution

The State of Container Security Standards

October 17, 2007
Author(s)
Shaw C. Feng, Simon P. Frechette
As cargo container security is a critical component in the U.S. homeland security, the communication among people in a chain of custody of a container needs to be timely and effective. Since people in the container custody chain often use different

Visualization, A Tool For Understanding Fire Dynamics

July 1, 2007
Author(s)
Glenn P. Forney
Computational tools have been developed at the National Institute of Standards and Technology (NIST) for modeling fire spread and smoke transport. These models include FDS (Fire Dynamics Simulator) for modeling fire spread and smoke transport and Smokeview

A Case Study in Enterprise Modelling for Interoperable Cross-Enterprise Data Exchange

February 1, 2007
Author(s)
Marija Jankovic, Nenad Ivezic, T Knothe, Zuran Marjanovic, Pat Snack
In this paper, we describe an approach to validate the capability of the ATHENA-enhanced enterprise modelling solutions to capture necessary cross-organizational business information in a computable form and to exchange partial models using a proposed

Magnetic resonances in atomic vapor excited by a mechanical resonator

December 1, 2006
Author(s)
Ying-ju Wang, Matt Eardley, Svenja A. Knappe, John Moreland, Leo W. Hollberg, John E. Kitching
We demonstrate a direct resonant interaction between the mechanical motion of a mesoscopic resonator and the spin degree of freedom of a sample of neutral atoms in the gas phase. This coupling, mediated by a magnetic particle attached to the tip of the

Synchronizing Multimodal Data Streams Acquired Using Commodity Hardware

November 27, 2006
Author(s)
Martial Michel, Vincent M. Stanford
We have developed tools and techniques that allow video frame level synchronization of multiple free-running commodity video cameras, microphones, and computer nodes using non-realtime operating systems. The techniques rely on physical audiovisual

Pose of I-Beams for Construction Site Automation

September 21, 2004
Author(s)
David E. Gilsinn, Geraldine S. Cheok, Alan M. Lytle
Automation of construction processes can result in reduced project costs and increased worker safety. A process that lends itself to automation is the picking and placing of objects. However, determining the pose (position and orientation) of an object is

Software Fault Complexity and Implications for Software Testing

June 16, 2004
Author(s)
D. Richard Kuhn, D Wallace, A M. Gallo
Exhaustive testing of computer software is intractable, but empirical studies of software failures suggest that testing can in some cases be effectively exhaustive. Data reported in this study and others show that software failures in a variety of domains
