Fast Methods for Finding Multiple Effective Influencers in Real Networks

December 31, 2020
Author(s)
Fern Y. Hunt, Roldan Pozo
We present scalable first hitting time methods for finding a collection of nodes that enables the fastest time for the spread of consensus in a network. That is, given a graph G = (V,E) and a natural number k, these methods find k vertices in G that

Cowan code: 50 years of growing impact on atomic physics

July 2, 2019
Author(s)
Alexander Kramida
The famous Cowan's book "The Theory of Atomic Structure and Spectra" published in 1981 and his suite of computer codes based on it continue to be highly influential in atomic physics and many other researchareas. As of September 2018, there are more than

Exploratory Lens Model of Decision-Making in a Potential Phishing Attack Scenario

October 10, 2017
Author(s)
Franklin Tamborello, Kristen K. Greene
Phishing, the transmission of a message spoofing a legitimate sender about a legitimate subject with intent to perform malicious activity, causes a tremendous and rapidly-increasing amount of damage to American information systems and users annually. This

STEP File Analyzer Software

March 30, 2017
Author(s)
Robert R. Lipman
The STEP File Analyzer is a software tool that generates a spreadsheet or CSV files from a STEP (ISO 10303 –STandard for Exchange of Product model data) Part 21 file. STEP files are used to represent product and manufacturing information (PMI) and for data

Using Visualization To Better Understand Fire Dynamics

February 19, 2017
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

What a User Should Know About Selecting an Evacuation Model

February 19, 2017
Author(s)
Erica D. Kuligowski, Steve M. Gwynne
In recent years, evacuation models have been increasingly applied in an attempt to understand the outcome of emergency egress scenarios. This has been due to the introduction of performance-based codes and the availability of cost-effective, high

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

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

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
