Performance Evaluation of Low Rate WPANs for Sensors and Medical Applications

November 1, 2004
Author(s)
Nada T. Golmie, David E. Cypher, O Rebala
We examine the performance of multimodal biometric authentication systems using state-of-the-art Commercial Off-the-Shelf (COTS) fingerprint and face biometric systems on a population approaching 1,000 individuals. Majority of prior studies of multimodal

Toward a Formal Common Information Model Ontology

November 1, 2004
Author(s)
Stephen Quirolgico, P Assis, A Westerinen, M Baskey, E Stokes
Self-managing systems will be highly dependent upon information acquired from disparate applications, devices, components and subsystems. To be effectively managed, such information will need to conform to a common model. One standard that provides a

Guide to Public Safety Applications of Wireless Technology

October 1, 2004
Author(s)
Leonard E. Miller
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

Resource Planning and Bandwidth Allocation in Hybrid Fiber-Coax Residential Networks

October 1, 2004

Securely Connecting the World with Cyber Security Standards

October 1, 2004
Author(s)
Alicia Clay Jones, Michael Hogan
This paper focuses on some of the key roles that cyber security standards play in securely connecting our cyber world. Cyber security standards can be categorized as technical, management, or testing standards. All three types of standards are necessary to

Information Security in the System Development Life Cycle

September 1, 2004
Author(s)
Annabelle Lee, Tanya L. Brewer
Many system development life cycle (SDLC) models exist that can be used by an organization to effectively develop an information system. Security should be incorporated into all phases, from initiation to disposition, of an SDLC model. This Bulletin lays

Rate Adaptive Video Transmission Over Ad-Hoc Networks

September 1, 2004
Author(s)
Hamid Gharavi, K Ban
In mobile ad-hoc network environments where the network topology is expected to change considerably, providing reliable video communications is a challenging task. This paper is mainly concerned with developing a packet control mechanism to reduce bursts

Software Fault Complexity and Implications for Software Testing

June 16, 2004
Author(s)
D. Richard Kuhn, D Wallace, A M. Gallo
Exhaustive testing of computer software is intractable, but empirical studies of software failures suggest that testing can in some cases be effectively exhaustive. Data reported in this study and others show that software failures in a variety of domains

Improving the Usability and Accessibility of Voting Systems and Products

May 7, 2004
Author(s)
Sharon J. Laskowski, James H. Yen, Marguerite W. Autry, J Cuginin, William H. Killam
The goal of this report is to describe how research and best practices from the human factors, human-machine and human-computer interaction, and usability engineering disciplines can be brought to bear to improve the usability and accessibility of voting
