WIND DRIVEN FIRES IN STRUCTURES

July 1, 2010
Author(s)
Daniel M. Madrzykowski, Stephen Kerber
Fires in high-rise buildings create unique safety challenges for building occupants and fire fighters. Smoke and heat spreading through the corridors and the stairs of a building during a fire can limit building occupants ability to escape and can limit

Computer-Controlled Thermal Cycling Tool to Aid in SiC Module Package Characterization

June 30, 2010
Author(s)
Madelaine H. Hernandez, Jose M. Ortiz, Brian J. Grummel, Allen R. Hefner Jr., David W. Berning, Colleen E. Hood, Patrick McCluskey
A software-controlled thermal cycling test system developed for SiC module package characterization is presented. Its interface permits the flexible definition of testing parameters like variable data acquisition rates and customizable cycle transitions

Developing a Sustainability Manufacturing Maturity Model

June 30, 2010
Author(s)
Mahesh Mani
Sustainable manufacturing (SM) broadly implies the development of innovative manufacturing sciences and technologies that span the life cycle of products and services to minimize negative environmental impacts, conserve energy and natural resources, are

Forensics Web Services

June 30, 2010
Author(s)
Anoop Singhal, Murat Gunestas, Duminda Wijesekera
Web services are currently a preferred way to architect and provide complex services. This complexity arises due to the composition of new services and dynamically invoking existing services. These compositions create service inter-dependencies that can be

Human Assisted Speaker Recognition in NIST 2010 Speaker Recognition Evaluation

June 30, 2010
Author(s)
Alvin F. Martin, Craig S. Greenberg
The 2010 NIST Speaker Recognition Evaluation or SRE10 (see SLTC Newsletter, July 2010) included a pilot test of human assisted speaker recognition (HASR). This test, which was open to sites whether or not they participated in the main evaluation of fully

Interim Report on the Examination of Corrosion Damage in Homes Constructed with Imported Wallboard: Examination of Samples Received September 28, 2009

June 30, 2010
Author(s)
David J. Pitchure, Richard E. Ricker, Maureen E. Williams, Sandra W. Claggett
Since many household systems are fabricated with metallic materials, changes to the household environment that accelerate corrosion will increase the failure rates of these systems. Recently, increased failure rates have been reported in homes constructed

Investigating the Bag-of-Words Method for 3D Shape Retrieval

June 30, 2010
Author(s)
Afzal A. Godil, Xiaolan Li
This paper investigates the capabilities of the Bag-of-Words (BW) method in the 3D shape retrieval field. The contributions of this paper are: 1) the 3D shape retrieval task is categorized from different points of view: specific vs. generic, partial-to

July 2010 SRM Spotlight

June 30, 2010
Author(s)
Regina R. Montgomery
The SRM Spotlight is a newsletter published by the Measurement Services Division for users of NIST standard reference materials. The Spotlight announces new reference materials and provides information about their use. In addition, this newsletter contains

Linking the Results of CIPM and RMO Key Comparisons with Linear Trends

June 30, 2010
Author(s)
Nien F. Zhang
A statistical approach to link the results of interlaboratory comparisons with linear trends is proposed. This approach can be applied to the case that the comparisons have the same nominal values or of a same magnitude. The degrees of equivalence between

Modeling Reactive Wetting when Inertial Effects are Dominant

June 30, 2010
Author(s)
Daniel Wheeler, James A. Warren, William J. Boettinger
Recent experimental studies of molten metal droplets wetting and spreading on high temperature reactive substrates have established that the majority of triple-line motion occurs when inertial effects are dominant. In light of these studies, this paper

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

Performance Measurements for Evaluating Static and Dynamic Multiple Human Detection and Tracking Systems in Unstructured Environments

June 30, 2010
Author(s)
Bodt Bodt, Richard Camden, Harry A. Scott, Adam S. Jacoff, Tsai H. Hong, Tommy Chang, Richard J. Norcross, Anthony Downs, Ann Virts
The Army Research Laboratory (ARL) Robotics Collaborative Technology Alliance (CTA) conducted an assessment and evaluation of multiple algorithms for real-time detection of pedestrians in Laser Detection and Ranging (LADAR) and video sensor data taken from

Standard Photoacoustic Spectrometer: Model and Validation using O2 A-Band Spectra

June 30, 2010
Author(s)
Keith A. Gillis, Daniel K. Havey, Joseph T. Hodges
We model and measure the absolute response of an intensity-modulated photoacoustic spectrometer comprising a 10 cm long resonator and having a Q-factor of approximately 30. We present a detailed theoretical analysis of the system and predict its response

Thermodynamic model of hydride formation and dissolution in spherical particles

June 30, 2010
Author(s)
Yuri Mishin, William J. Boettinger
A model of hydride formation and dissolution has been proposed for a single spherical nano-particle and for a colletion of such particles with a given size distribution. The phase transformation strain gives rise to an elastic barrier of the transformation

Towards Improved Forklift Safety

June 30, 2010
Author(s)
Roger V. Bostelman
This paper is structured to first summarize information from special session papers presenting statistics and issues which define the forklift safety challenge. Following are current remedies presented and discussed during the session that can improve

Author(s)
Daniel G. Friend
This is a Powerpoint presentation given as a talk at Scientific Data Management (SDM) for Government Agencies Workshop to Improve SDM, 29 June 2010,Washington, DC (USA.)

Double-Resonance Lineshapes in a Cell with Wall Coating and Buffer Gas

June 28, 2010
Author(s)
Svenja A. Knappe, Hugh Robinson
Microwave double resonances were measured is a wall-coated Rb vapor cell as a function of additional buffer gas pressure. These data were compared to similar measurements in an uncoated cell. It was found that the linewidth in the coated cell displays a
