Crystal Structures of Calcium Orthophosphates

December 1, 2001
Author(s)
M Mathew, Shozo Takagi
Calcium phosphates comprise the largest group of biominerals in vertebrate animals. They also have many uses in industry, medicine and everyday life. Orthophosphates are salts of the tribasic phosphoric acid which include H 2PO 4-, HPO 4 2- and PO 4 3-

Measurement of Shielding Effectiveness of Electrically-Small Enclosures

August 13, 2011
Author(s)
Christopher L. Holloway, Colton R. Dunlap, John M. Ladbury, Joshua A. Gordon, Jason B. Coder, Galen H. Koepke
In the following we propose a technique for determining the shielding effectiveness (SE) an electrically small enclosure. In particular, we use this technique to explore the shielding characteristics of a rectangular box used to shield a satellite based

Pseudo-Exhaustive Testing for Software

April 28, 2006
Author(s)
David R. Kuhn, Vadim Okun
Pseudo-exhaustive testing uses the empirical observation that, for broad classes of software, a fault is likely triggered by only a few variables interacting. The method takes advantage of two relatively recent advances in software engineering: algorithms

Uncertainty Assessment of Equations of State with Application to an Organic Rankine Cycle

July 2, 2017
Author(s)
Jerome Frutiger, Ian Bell, O'Connell J. P., Kenneth Kroenlein, Jens Abildskov, Gurkan Sin
Evaluations of equations of state (EoS) with application to process systems should include uncertainty analysis. A generic method is presented for determining such uncertainties from both the mathematical form and the data for obtaining EoS parameter
