Development of a MEMS based Dynamic Rheometer

August 31, 2010
Author(s)
Gordon Christopher, Jae M. Yoo, Nicholas G. Dagalakis, Steven D. Hudson, Kalman D. Migler
Rheological methods that interrogate nano-liter scale volumes of fluids and solids have advanced considerably over the past decade, yet there remains a need for methods that probe the frequency dependent complex rheological moduli through application of

Framework and Indicators for a Sustainable Manufacturing Mapping Methodology

August 31, 2010
Author(s)
Marja Paju, Juhani Heilala, Markku Hentula, Antti Heikkila, Bjorn Johansson, Swee K. Leong, Kevin W. Lyons
Increasing numbers of companies in the manufacturing industry have identified market potential for implementing sustainable and green manufacturing. Yet, current sustainability assessment tools for companies are complicated, requiring vast amounts of data

Introduction: Cybersecurity

August 31, 2010
Author(s)
David R. Kuhn
Enterprise security, often considered a burden for system administrators and users alike, is one of the most rapidly evolving areas of IT. The articles in this issue can help IT professionals who want to be intelligent providers or consumers of secure

OntoSTEP: Enriching Product Model Data Using Ontologies

August 31, 2010
Author(s)
Raphael Barbau, Sylvere I. Krima, Xenia Fiorentini, Sudarsan Rachuri, Anantha Narayanan Narayanan, Sebti Foufou, Ram D. Sriram
The representation and management of product lifecycle information is critical to the success of any manufacturing organization. Different modeling languages are adopted to represent different product information, for example EXPRESS for geometry as seen

Summary of the NIST Workshop on Sustainable Manufacturing: Metrics, Standards, and Infrastructure

August 31, 2010
Author(s)
Sudarsan Rachuri, Ram D. Sriram, Anantha Narayanan Narayanan, Prabir Sarkar, Jae H. Lee, Kevin W. Lyons, Vijay Srinivasan, Sharon J. Kemmerer
This paper summarizes the presentations, discussions, and recommendations of the NIST Workshop Sustainable Manufacturing: Metrics, Standards, and Infrastructure held at NIST, Gaithersburg, Maryland, USA, October 13th through October 15th, 2009. The primary

System Testing Using Use Cases for Simulation Model of an Emergency Room

August 31, 2010
Author(s)
Guodong Shao
Modeling and simulation (M&S) techniques are increasingly being used to solve problems and aid decision making in many different fields. It is particularly useful for Department of Homeland Security (DHS) applications because of its feature of non

Efficient photon pair sources based on Silicon-on-Insulator microresonators

August 30, 2010
Author(s)
Jun Chen, Zachary H. Levine, Jingyun Fan, Alan L. Migdall
We present a general quantum-mechanical formalism to describe photon pair generation via four-wave mixing in a Silicon-on-Insulator (SOI) microresonator. We also provide design principles for efficient photon-pair generation in a SOI microresonator through

Theory for a Dissipative Droplet Soliton Excited by a Spin Torque Nanocontact

August 30, 2010
Author(s)
Mark Hoefer, Thomas J. Silva, Mark W. Keller
A distinct type of solitary wave is predicted to form in spin torque oscillators when the free layer has a sufficiently large perpendicular anisotropy. In this structure, which is a dissipative version of the conservative droplet soliton originally studied

Towards Improved End-to-End System Efficiency of Photon Pair systems

August 30, 2010
Author(s)
Alexander E. Ling, Alan L. Migdall, Jingyun Fan
We report on our efforts in integrating a source and detection system of photon pairs that have a high end-to-end system efficiency. This requires combining appropriate detectors and photon pair sources. Preliminary measurements show that an observed

Trade Collaboration Systems

August 30, 2010
Author(s)
Peter O. Denno
A trade collaboration system (TCS) is a system designed to coordinate the work of supply chain stakeholders involved in the business processes of global logistics. Using the Software as a Service (SaaS) model, the TCS provides a cohesive, process-oriented

Building Occupant Egress Data

August 27, 2010
Author(s)
Richard D. Peacock, Erica D. Kuligowski
Data on people movement on stairs were collected from 9 office and residential building evacuations in the United States. The buildings involved in this study range from 6 stories to 62 stories in height. The data were collected by positioning video

Characterization of Two Spectrmeters in Support of the Landsat Data Continuity Mission

August 27, 2010
Author(s)
Bettye C. Johnson, Robert D. Saunders, Zhigang Li, Abra Fein, Lawrence Ong, Milton Hom, Robert Barnes, B L. Markham
The Landsat Data Continuity Mission (LDCM) project at the National Aeronautics and Space Administration (NASA)Goddard Space Flight Center (GSFC) is supervising the manufacture and calibration of the Operational Land Imager (OLI) satellite instrument by

Carbon Nanotubes: Measuring Dispersion and Length

August 26, 2010
Author(s)
Jeffrey A. Fagan, Barry J. Bauer, Erik K. Hobbie, Matthew Becker, Angela R. Hight Walker, Jeffrey R. Simpson, Jae H. Chun, Jan Obrzut, Vardhan Bajpai, Frederick R. Phelan Jr., Daneesh O. Simien, JiYeon Huh, Kalman D. Migler
Advanced technological uses of single-wall carbon nanotubes (SWCNTs) rely on the production of single length and chirality populations that are currently only available through liquid phase post processing. The foundation of all of these processing steps
