Approach to Modeling Flame Spread Over Polyurethane Foam-Covered Walls. (POSTER ABSTRACTS)

September 1, 2005
Author(s)
Daniel M. Madrzykowski, Stephen Kerber, Nelson P. Bryner, William L. Grosshandler
Computer simulation has been demonstrated to be credible, when properly applied, as a tool to help fill in critical details of a fire incident and to demonstrate the value of alternative building designs and fire safety measures. This poster presents the

An Overview and Analysis of PDA Forensic Tools

April 2, 2005
Author(s)
Wayne Jansen, Richard Ayers
Mobile handheld devices are becoming evermore affordable and commonplace in society. When they are involved in a security incident or crime, forensic specialists require tools that allow proper extraction and speedy examination of any digital evidence

Second Harmonic Magneto-Resistive Imaging to Authenticate and Recover Data from Magnetic Storage Media

March 1, 2005
Author(s)
David P. Pappas, Alexey Nazarov, D Stevenson, Steven Voran, Mike E. Read, Erin M. Gormley, James Cash, Ken Marr, James Ryan
A scanning magneto-resistive (MR) microscope was developed for high resolution imaging of magnetic tapes and digital media. Second harmonic detection was used to remove thermal anomalies. We were able to image sufficient lengths of tape for authentication

PDA Forensic Tools: an Overview and Analysis

August 1, 2004
Author(s)
Richard Ayers, Wayne Jansen
Adequate user authentication is a persistent problem, particularly with mobile devices such as Personal Digital Assistants (PDAs), which tend to be highly personal and at the fringes of an organization's influence. Yet these devices are being used

Multiplexed Assays for Evaluation of Y-SNP Markers in U.S. Populations

April 1, 2004
Author(s)
Peter Vallone, John Butler
Genetic markers located on the Y chromosome are of increasing importance in human identity testing. In an effort to evaluate the forensic utility of Y chromosome single nucleotide polymorphism (SNP) markers, we constructed several novel multiplex allele

Highly Multiplexed Assays for Measuring Polymorphisms on the Y-Chromosome

October 17, 2003
Author(s)
John M. Butler, R Schoske, Peter Vallone
A multiplex PCR assay capable of amplifying 20 Y chromosome short tandem repeat (STR) markers simultaneously has been developed. These markers include all of the Y STRs that make up the extended haplotype used in Europe (DYS19, DYS385, DYS389I/II, DYS390

NIST RM (Reference Material) 8240/8250 Standard Bullets and Casings Project

September 1, 2002
Author(s)
Jun-Feng Song, Theodore V. Vorburger, Susan M. Ballou, M Ols
The NIST RM (Reference Material) 8240/8250 Standard Bullets and Casings Project aims to support the National Integrated Ballistics Information Network (NIBIN) in the U.S. Two prototype standard bullets were developed in 1998 with all six lands manufactured

A New NIST Mitochondrial DNA Interactive Website

August 1, 2002
Author(s)
Barbara C. Levin, L A. Tully, Diane K. Hancock, Frederick P. Schwarz, M S. Lee
Every human cell has from a few dozen to several thousand mitochondria each of which contain mitochondrial DNA (mtDNA). The sequence of the entire human mtDNA (16,569 base pairs) was determined and published by Anderson et al. in 1981. A mtDNA standard

Setup and Test Procedures dd (GNU Fileutils) 4.0.36 Forensic Tests

August 1, 2002
Author(s)
James R. Lyle
This document describes the testing of dd (GNU fileutils) 4.0.36 as a disk imaging tool on a Linux platform. The Linux version used was Linux version 2.4.2-2 (Red Hat Linux 7.1 2.96-79). The test cases that were applied are described in Disk Imaging Tool

Development of Y STR Megaplex Assays

December 1, 2001
Author(s)
R Schoske, John Butler, Peter Vallone, Margaret C. Kline, M. Prinz, A J. Redd, M F. Hammer
Y Chromosome short tandem repeat markers have a number of applications in human identity testing including typing the perpetrator of sexual assault cases without differential extraction and tracing paternal lineages for missing person investigations. In
