Lessons Learned in Wireless Monitoring

October 2, 2005
Author(s)
William M. Healy
The emergence of wireless communications technology has led to an increasing interest in sensors that are free from wiring constraints that increase the cost of installation of a sensor network and create a confusing collection of wires in a building. In

A Cross-Correlation Based Method for Spatial-Temporal Traffic Analysis

October 1, 2005
Author(s)
Kevin L. Mills, Y. L. Jiang
We have implemented a quantum key distribution (QKD) system with polarization encoding at 850 nm over 1 km of optical fiber. The high-speed management of the bit-stream, generation of random numbers and processing of the sifting algorithm are all handled

A Diner's Guide to Evaluating a Framework for Ubiquitous Computing Applications

October 1, 2005
Author(s)
Mary F. Theofanos, Jean C. Scholtz
There is a clear need for evaluation methodologies specifically suited to ubiquitous computing applications. Here we investigate a user evaluation framework we proposed earlier which draws upon traditional desktop methods, but carefully adapts them based

A Model-Based Analysis of First-Generation Service Discovery Systems

October 1, 2005
Author(s)
Christopher E. Dabrowski, Kevin L. Mills, Stephen Quirolgico
Future commercial software systems will be based on distributed service-oriented architectures in which applications are composed dynamically from remote components. A key part of service-oriented computing is the ability for clients to discover remote

A Questionnaire to Assess the Difficulty of Open Source Analysis Taskings

October 1, 2005
Author(s)
T T. Hewett, Jean C. Scholtz
Our goal is to produce metrics for assessing the impact of software tools and environments produced for the intelligence community. To this end we are developing a task difficulty questionnaire to attempt to identify and assess the impact of task

A Tool Kit to Generate 3D Animated CAESAR Bodies

October 1, 2005
Author(s)
Quandou (. Wang, Sanford P. Ressler
The Civilian American and European Surface Anthropometry Resource (CAESAR) database provides a comprehensive source for body measurement in numerous industries such as apparel, aerospace, and automobile. Generating animated CAESAR body sequences from still

An Efficient Power-Saving Mechanism for Integration of WLAN and WWAN Networks

October 1, 2005
Author(s)
San-Nan K. Lee, S H. Seo, Nada T. Golmie
We have implemented a quantum key distribution (QKD) system with polarization encoding at 850 nm over 1 km of optical fiber. The high-speed management of the bit-stream, generation of random numbers and processing of the sifting algorithm are all handled

Carbon Nanotube-Based Coatings for Laser Power and Energy Measurements

October 1, 2005
Author(s)
John H. Lehman, Natalia Varaksa, Evangelos Theocharous, Anne Dillon
We describe carbon nanotube (CNT) based coatings for thermal detectors for laser power and energy measurements. The value of thermal properties of CNTs obtained from the literature indicates that such coatings have desirable properties such as low thermal

Channel-Adaptive Relaying in Mobile Ad Hoc Networks with Fading

October 1, 2005
Author(s)
Michael R. Souryal, Nader Moayeri
This paper describes an approach for relaying in multihop networks that adapts to the time-varying channel and exploits spatial diversity to mitigate multipath fading. Ignored in some simulation-based performance analyses, fading arises from multipath

Characterization of Normally-off SiC Vertical JFET Devices and Inverter Circuits

October 1, 2005
Author(s)
Jih-Sheng Lai, H. Yu, J. Zhang, Y. Li, Kuang Sheng, J.H. Zhao, Allen R. Hefner Jr.
A normally-off SiC JFETs has been characterized under static and dynamic operating conditions. Two application oriented inverter circuits were constructed for additional tests under soft- and hard-switching conditions. The single-phase soft-switching

Combinatorial Materials Synthesis and High-Throughput Characterization

October 1, 2005
Author(s)
Ichiro Takeuchi, Lauterbach Jochen, Michael J. Fasolka
The pace at which major technological changes take place is often dictated by the rate at which new materials are discovered, and timely arrival of new materials has always played a key role in bringing advances to our society. There is no wonder then that

CPM: A Core Model for Product Data

October 1, 2005
Author(s)
Steven J. Fenves, Sebti Foufou, Conrad Bock, Ram D. Sriram
The support of PLM throughout the product life, from the product?s conceptualization to its disposal, requires reliable, complete and efficient data models. The Core Product Model (CPM), initially developed at NIST for a number of in-house research

Criteria for Exact Qudit Universality

October 1, 2005
Author(s)
Stephen Bullock, G K. Brennen, Dianne M. O'Leary
The n-qubit concurrence canonical decomposition (CCD) is a generalization of the two-qubit canonical decomposition SU(4)=[SU(2) (x) SU(2)] ? [SU(2) (x) SU(2)], where ? is the commutative group which phases the maximally entangled Bell basis. A prequel

Developing a Difficulty Metric for Open Source Analytic Tasks

October 1, 2005
Author(s)
T T. Hewett, Jean C. Scholtz
Our goal is to produce metrics for assessing the impact of software tools and environments produced for the intelligence community. To this end we need to understand the variables that make some analytic tasks harder than others and to determine which data
