Investigating Global Behavior in Computing Grids

September 1, 2006
Author(s)
Kevin L. Mills, Christopher E. Dabrowski
This paper presents an executable model of grid computing systems and a measurement approach, based on multidimensional analysis, to understand global behavior in a complex system. Specifically, we investigate effects of spoofing attacks on the scheduling

Legal and Technical Measurement Requirements for Time and Frequency

September 1, 2006
Author(s)
Michael A. Lombardi
This paper discusses various technologies and applications that rely on precise time and frequency, and explores their legal and technical requirements for measurement uncertainty. The technologies and applications discussed include financial markets, the

Message Validation with a Semantic Reasoning Tools

September 1, 2006
Author(s)
Peter O. Denno, Nenad Ivezic
This paper describes challenges encountered in the development of a tool to validate OASIS UBL-based (Universal Business Language) messages. The software tool is ontology-based, using first-order logic and parts of the Suggested Upper Merged Ontology (SUMO

Microwave Spectrum of the Heterodimers: CH 3 OH-CO 2 and CH 3 OH-H 2 CO

September 1, 2006
Author(s)
Vadim V. Ilyushin, Francis J. Lovas, David F. Plusquellic
Molecular complexes, dimers and heterodimers, often show interesting structures, large amplitude internal motions and orientations for reaction coordinates. These properties were the motivations for the current study of the rotational spectra of the

Part-part Relations in an RDF/S and OWL Extension

September 1, 2006
Author(s)
Conrad E. Bock
This describes an extension to the Resource Description Framework/Schema (RDF/S) to specify relations between parts of the same whole (composite structure). For example, the relation between engine and wheels in a car applies in each individual car, rather

Proposal for Development of a National Microwave Brightness-Temperature Standard

September 1, 2006
Author(s)
James P. Randa, Amanda Cox, Dave K. Walker
We review the advantages of a national standard for microwave brightness temperature and outline our proposed approach toward developing such a standard. The proposal is a combined standard that would comprise both a standard radiometer, traceable to

Raman Spectroscopic Monitoring of Droplet Polymerization in a Microfluidic Device

September 1, 2006
Author(s)
Susan E. Barnes, Zuzanna T. Cygan, Kathryn Beers, Eric J. Amis, Jesse K. Yates
Thiolene based microfluidic devices were used to generate droplets of benzyl methacrylate monomer and hexanediol dimethacrylate crosslinker mixtures suspended in a water/surfactant continuous phase. A gradient of droplet composition was established and the

Round Robin Study of Total Heat Flux Gauge Calibration at Fire Laboratories.

September 1, 2006
Author(s)
William M. Pitts, A V. Murthy, J L. Deris, J R. Filtz, K Nygard, D Smith, I Wetterlund
Total heat flux gauges are widely employed in fire research and fire testing laboratories. Several fire laboratories have developed systems for calibrating these gauges. There are major differences between these calibration facilities, and prior to this

SAMATE's Contribution to Information Assurance

September 1, 2006
Author(s)
Paul E. Black
The amount of software in today's information world is far too large to check manually. Automated tools are a must. These tools can help design and build the right software in the first place, but they can also help if the system being designed includes

Smart Card Authentication for Mobile Devices

September 1, 2006
Author(s)
Wayne Jansen, Serban I. Gavrila, Clement Seveillac
While mobile handheld devices provide productivity benefits, they also pose new risks. User authentication is the best safeguard against the risk of unauthorized use and access to a device¿s contents. This paper describes two novel types of smart card with
