Acceptor Doping of Barium Strontium Titanate and Magnesium Oxide Composites

January 1, 2000
Author(s)
J. Synowczynski, G. Dewing, Richard G. Geyer, John H. Grosvenor Jr
The microwave dielectric properties of bulk barium strontium titanate and magnesium oxide ceramic composites are measured with cylindrical mode-filtered cavity and dielectric sleeve resonator techniques. The cylindrical wall of the mode- filtered cavity

Adsorption of Dodecahydroxylated-Fullerene Monolayers at the Air Water Interface

January 1, 2000
Author(s)
Li Piin Sung, W J. Liua, U Jeng, T L. Lin, S H. Laib, M C. Shih, C S. Tsao, L Y. Wang
We study the adsorption behaviors of dodecahydroxylated-fullerene C60(OH)12 at the air-water interface. With the hydrophilicity imposed by the 12 hydroxy groups randomly bounded on the C60 cage, C60(OH)12 can dissolve in water slightly. Surface pressure

Advanced Propellant/Additive Development for Fire Suppressing Gas Generators

January 1, 2000
Author(s)
Stephen Fallis, Russell Reed, Paul Wierenga, Gary Holland, Yue-Cherng Lu
The “Advanced Propellant/Additive Development for Gas Generator” project is a collaborative effort between Primex Aerospace Company (PAC) and the Naval Air Warfare Center-Weapons Division (NAWCWD) at China Lake, CA. The objective of this NGP project is to

Algebraic Constraints Implying Monotonicity for Cubics

January 1, 2000
Author(s)
Charles D. Fenimore, John M. Libert, M. Brill
While it is straightforward to formulate constraints which ensure a cubic polynomial is monotonic on an interval, such constraints may not be in a form which is suitable for use in standard optimization software. The MATLAB package is typical; the required

An Analysis of Existing Ontological Systems for Applications in Manufacturing

January 1, 2000
Author(s)
Craig I. Schlenoff, Peter O. Denno, Robert W. Ivester, Simon Szykman, Don E. Libes
The objective of this work described in this paper is to move closer to the ultimate goal of seamless system integration using the principle behind ontological engineering to unambiguously define domain-specific concepts. Current integration efforts are

An Automated Benchmarking Toolset

January 1, 2000
Author(s)
M M. Courson, G J. Marcais, Alan Mink, B Traverse
The performance drive of parallel computing and platform upgrades or replacements are among the reasons frequent running of benchmark codes has become commonplace for application and platform evaluation and tuning. NIST is developing a prototype for an

An Optical Sensor for Polymer Injection Molding

January 1, 2000
Author(s)
Anthony J. Bur, C L. Thomas
An optical sensor using fiber optics to access the mold cavity was used to monitor the mold filling and cooling phases of injection molding. The sensor consists of a sapphire window at the end of a sleeved ejector pin into which an optical fiber is
