Predicting Macroscopic Dynamics in Large Distributed Systems

July 18, 2011
Author(s)
Kevin L. Mills, James J. Filliben
In this paper, we outline an approach that can be used to predict macroscopic dynamics when new components are deployed in a large distributed system. Our approach combines two main methods: scale reduction and multidimensional data analysis techniques

The Effect of Folding on the Mechanical Properties and Internal Structures of Fibers Used in Ballistic Applications

July 18, 2011
Author(s)
Haruki Kobayashi, Walter G. McDonough, Hae-Jeong Lee, Jae H. Kim, Amanda L. Forster, Kirk D. Rice, Gale A. Holmes
The failure of a first responder's soft body armor (SBA) composed of poly (p-phenylene benzobisoxazole) (PBO) fibers has prompted researchers to assess the long-term durability and effectiveness of current and future SBA products. Based on existing data

The Proper Use of Substitute Test Fluids

July 18, 2011
Author(s)
Marc A. Buttler
Liquid-measuring devices are used in many different commercial applications. The vast array of liquid products that are measured includes some products that may pose difficulties in testing. NIST Handbook 44 allows for substitution of fluids during testing

Incorporation of Defects into the Central Atoms Model of a Metallic Glass

July 17, 2011
Author(s)
Eric Lass, Aiwu Zhu, Gary J. Shiflet, S J. Poon
The central atoms model (CAM) of a metallic glass is extended to incorporate thermodynamically stable defects, similar to vacancies in a crystalline solid, within the amorphous structure. A bond deficiency (BD), which is the proposed defect present in all

On the Security of Hash Functions Employing Blockcipher Postprocessing

July 14, 2011
Author(s)
Dong H. Chang, Mridul Nandi, Moti Yung
Analyzing desired generic properties of hash functions is an important current area in cryptography. For example, in Eurocrypt 2009, Dodis, Ristenpart and Shrimpton introduced the elegant notion of "Preimage Awareness" (PrA) of a hash function H^P , and

Comparison of Gas Velocity Measurements and CFD Predictions in the Exhaust Duct of a Stationary Source

July 13, 2011
Author(s)
Rodney A. Bryant, Olatunde B. Sanni, Elizabeth F. Moore, Robert P. Borthwick, Marco G. Fernandez, Iosif I. Shinder, Jiann C. Yang, Aaron N. Johnson
Two series of independent flow measurements were conducted for cross validation of flow velocity in the exhaust duct of the NIST Large Fire Laboratory. In the first series, two pressure measurement probe types, an S probe and a 3-D probe, were used to
