Long term stability of ultra high molar mass polyethylene fibres

September 19, 2016
Author(s)
Amanda L. Forster, Aaron M. Forster, Joannie W. Chin, Sylvain H. Petit, Kai-Li Kang, Nicholas G. Paulter Jr., Kirk D. Rice, Don Jenket II, Mohamad Al-Sheikhly
Abstract. The performance of ultra-high molar mass polyethylene (UHMMPE) fibres for ballistic protection is predicated on the development of a highly aligned molecular structure that allows the polymer to exhibit a superior strength in the axial direction

Test method for measuring the electrical output of electroshock weapons

July 25, 2016
Author(s)
Nicholas G. Paulter Jr., David M. Jenkins, Norimitsu Ichikawa, Michael Leonesio
Electroshock weapons (ESWs) have become a ubiquitous component of weapons used in the arsenal of domestic law enforcement (LE) agencies and the military around the world. It is a major contributor to the escalation of force policies and procedures of many

Long-Term Stability of UHMWPE Fibers

February 18, 2015
Author(s)
Amanda L. Forster, Aaron M. Forster, Joannie W. Chin, Chiao-Chi Lin, Sylvain H. Petit, Kai-Li Kang, Nicholas G. Paulter Jr., Michael A. Riley, Kirk D. Rice
The superior performance of ultra-high molecular weight polyethylene fi bers is predicated on the development of a highly aligned molecular structure that allows the polymer to exhibit a superior strength in the axial direction of the fi ber. Body armor

Natural Scene Statistics in Infrared Images

December 12, 2014
Author(s)
Nicholas G. Paulter Jr., Todd R. Goodall, Alan C. Bovik
Natural Scene Statistics (NSS) produces powerful perceptually relevant tools that have been highly successful in image quality analysis of visible light images. These NSS capture statistical regularities in the physical world and thus can be applicable to

Image Quality Testing: Selection of Images for Assessing Test Subject Input

September 2, 2014
Author(s)
John R. Jendzurski, Nicholas G. Paulter Jr.
Determining image quality is dependent to some degree on human interpretation. Although entirely subjective methods of evaluating image quality may be adequate for consumer applications, they are not acceptable for security and safety applications where

Investigations of Near-Edge Ballistic Impacts on Law Enforcement Body Armor

September 1, 2014
Author(s)
Kirk D. Rice, Amanda L. Forster, Michael A. Riley, Nicholas Paulter
In 2005 and 2006, two law enforcement officer-involved shootings resulted in injuries to the officers when bullets were not stopped in the officers' body armor. In both cases, the bullets struck the officers' armor quite close to the edge of the ballistic

Standoff passive video imaging at 350 GHz with 251 superconducting detectors

June 20, 2014
Author(s)
Daniel T. Becker, James A. Beall, Hsiao-Mei Cho, Gene C. Hilton, Nicholas G. Paulter Jr., Carl D. Reintsema, Robert E. Schwall, Cale Gentry, Ilya Smirnov, Peter Ade, W D. Duncan, Mark Halpern, Carole Tucker
Millimeter wavelength radiation holds promise for detection of security threats at a distance, including suicide bomb belts and maritime threats in poor weather. The high sensitivity of superconducting Transition Edge Sensor (TES) detectors makes them

A Generative Model for Fingerprint Minutiae

June 4, 2013
Author(s)
Melissa K. Taylor, Nicholas G. Paulter Jr., Qijun Zhao, Yi Zhang, Anil K. Jain
Fingerprint minutiae are the most important features used by latent fingerprint examiners, as well as in automated fingerprint recognition systems. Hence, understanding the statistical distribution of minutiae is essential in many fingerprint recognition

A REFERENCE MEASUREMENT SYSTEM FOR ELECTROSHOCK WEAPONS

June 3, 2013
Author(s)
Nicholas G. Paulter Jr., Donald R. Larson
We have developed a measurement system to accurately measure the electrical current and high-voltage output of electroshock weapons (ESW) that are used to deliver an electrical stimulus to humans for the purpose of incapacitation. Since the output of

The Forthcoming IEEE Standard 1696 on Test Methods for Characterizing Circuit Probes

May 6, 2013
Author(s)
Nicholas Paulter, John Jendzurski, Mike McTigue, Bill Hagerup, Thomas E. Linnenbrink
The Technical Committee 10 (TC10) of the IEEE Instrumentation and Measurement Society initiated a new standards activity in 2006 for the development of test methods to characterize the performance of circuit probes. This standard contains a set of

Fingerprint Image Synthesis based on Statistical Feature Models

December 6, 2012
Author(s)
Nicholas G. Paulter Jr., Melissa Taylor, Anil K. Jain, Qijun Zhao
Fingerprint image synthesis has received considerable attention because of its potential use in generating large databases to evaluate the performance of fingerprint recognition systems. Existing fingerprint synthesis algorithms (e.g., SFinGe) focus on
