Spherical Test Objects for Hand-held Metal Detector Characterization

September 12, 2018
Author(s)
Nicholas G. Paulter Jr., Donald R. Larson, John A. Ely
Measuring the detection performance of metal detectors (hand-worn, hand-held, and walk-through models) is based on the observation of an alarm indication (light, sound, vibration) given by the metal detector when a threat or test object is present. These

Walk-through Metal Detector Testing and the Need to Emulate Natural Body Motion

July 5, 2018
Author(s)
Nicholas G. Paulter Jr., Donald R. Larson, Nicklaus F. Troje
The effect of motion through the portal of a walk-through metal detector (WTMD) has often been considered to contribute to the uncertainty in detecting threat objects being carried through the WTMD. However, typical metrological testing uses a robotic

Towards Developing Standardized Usability Evaluation Methodology for Public Safety Communications Technology: A User-Centered Approach

June 14, 2018
Author(s)
Kristen Greene, Shanee T. Dawkins, Yee-Yin Choong, Mary F. Theofanos, Sandra S. Prettyman, Susanne M. Furman, Michelle P. Steves
In public safety and homeland security, it is critical to understand technology users’ primary goals, the characteristics of the users, and the context in which they are operating. New and emerging technologies present opportunities and challenges for

Estimating Error Rates for Firearm Evidence Identifications in Forensic Science

March 1, 2018
Author(s)
Jun-Feng Song, Theodore V. Vorburger, Wei Chu, James H. Yen, Johannes A. Soons, D Ott, Nien F. Zhang
Estimating error rates for firearm evidence identification is a fundamental challenge in forensic science. This paper describes the recently developed Congruent Matching Cells (CMC) method for image comparisons, its application to firearm identification

Analysis of Wind Pressure Data on Components and Cladding of Low-Rise Buildings

December 1, 2017
Author(s)
Dat Duthinh, Joseph A. Main, Matthew L. Gierson, Brian M. Phillips
This paper presents a methodology for analyzing wind pressure data on cladding and components of low-rise buildings. The aerodynamic force acting on a specified area is obtained by summing up pressure time series measured at that area’s pressure taps times

Experimental Investigation of Firebrand Accumulation Zones in Front of Obstacles

December 1, 2017
Author(s)
Samuel L. Manzello, Sayaka Suzuki
It is well accepted that as structures are exposed to wind, stagnation planes are produced around structures. Past work by the authors demonstrated for the first-time that wind-driven firebrand showers may accumulate in these stagnation planes. While those

Ultrafast Laser Eyewear Protection: Measurements and Precautions

September 25, 2017
Author(s)
Christopher J. Stromberg, Joshua A. Hadler, Brian Alberding, Edwin J. Heilweil
Ultrafast laser systems are becoming more widespread throughout the research and industrial communities yet eye protection for these high power, bright pulsed sources still require scrupulous characterization and testing before use. Femtosecond lasers

Autonomous Relocation of Mobile Base Stations in Emergency Scenarios

September 12, 2017
Author(s)
Kamran Sayrafian, Ladan Rabieekenari, John Baras
Limited access to communication services is one of the challenges that emergency personnel and first responders could face during environmental disasters or other emergencies. Networking infrastructure can breakdown during a catastrophe. At the same time

Metrologies for Performance of Impact Mitigating Materials

June 12, 2017
Author(s)
Aaron M. Forster, Michael A. Riley
Soft non-linear materials are used to mitigate energy transfer between objects during high rate or frequency events. These impact mitigating materials (IMM) are used in a wide range of applications such as isolating rotating equipment, protecting buildings

Imposing Fine-grain Next Generation Access Control over Database Queries

May 25, 2017
Author(s)
David F. Ferraiolo, Serban I. Gavrila, Gopi Katwala, Joshua D. Roberts
In this paper we describe a system that leverages ANSI/INCITS Next Generation Access Control (NGAC) standard called Next-generation Database Access Control (NDAC) for accessing data in tables, rows, and columns in existing RDBMS products. NDAC imposes

Standardized Measurements of Collection Efficiency from Wipe-Sampling of Trace Explosives

April 10, 2017
Author(s)
Jennifer R. Verkouteren, Jeffrey A. Lawrence, Matthew E. Staymates, Edward R. Sisco
One of the limiting steps to detecting traces of explosives at screening venues is effective collection of the sample. Wipe-sampling is the most common procedure for collecting traces of explosives, and standardized measurements of collection efficiency
