Development Life Cycle and Tools for XML Content Models

September 1, 2004
Author(s)
Boonserm Kulvatunyou, KC Morris, Jeong Buhwan, Puja Goyal
… projects today rely on shared semantic models based on standards represented using Extensible Mark up Language (XML) … must be consistent and valid in terms of agreed upon standards and guidelines. In this paper, we describe an …

A Photoconductivity Technique for the Assessment of Pigment Reactivity

November 19, 2003
Author(s)
Joannie W. Chin, S J. Scierka, T Kim, Amanda L. Forster
Large volumes of titanium dioxide (TiO2) are utilized each year in coatings, sealants, plastics and paper for opacification and pigmentation purposes. It is well known that the photoreactivity of TiO2 can contribute to the degradation of the material that

Analysis of Effective Thermal Properties of Thermall Thick Materials

July 1, 2003
Author(s)
Frederick W. Mowrer
The standard methods used to derive effective thermal properties of thermally thick materials based on bench-scale radiant exposure tests are reviewed and analyzed. These methods are compared with numerical calculations for the same boundary conditions

A Thermodynamic Study of the Conversion of Chorismate to Isochorismate

August 1, 2000
Author(s)
Yadu D. Tewari, A M. Davis, Prasad T. Reddy, Robert N. Goldberg
Microcalorimetry and high performance liquid chromatography were used to conduct a thermodynamic investigation of the biochemical reaction chorismate(aq) = isochorismate(aq). this reaction occurs at the branch point of the chorismate metabolic pathway that

Absolute Interferometry With a 670 nm External Cavity Diode Laser

October 1, 1999
Author(s)
Jack A. Stone Jr., Alois Stejskal, Lowell P. Howard
In the last few years there has been much interest in the use of tunable diode lasers for absolute interferometry. Here we report on the use of an external cavity diode laser operating in the visible (λ{approximately} 670 nm) for absolute distance

Short-Term Stability Measurements of a Germanium Plotodiode Radiometer

October 1, 1998
Author(s)
G Andor, Bettye C. Johnson
This paper describes a general stability measurement method for the short term stability, or repeatability, for radiometers using fixed-point blackbodies [BBs] as radiation sources. A germanium photodiode was used for the detector in the radiometer. The

Data Model Development and Validation for Product Data Exchange

January 1, 1990
Author(s)
Mary Mitchell, Y Yang, S Ryan, B Martin
Data modeling techniques have been used extensively in the development of an emerging standard for the exchange of product design and manufacturing information. PDES, Inc., an industry cooperative, is applying resources to accelerate the development and

September 20, 2012
Author(s)
Kenneth S. Butcher
This handbook provides guidance to extablish a management system of State Fuel Quality Laboratories (FQL) using the International Organization for Standardization (ISO) International Electrotechnical Commission (IEC) ISO/IEC 17025:2005, "General

Computer Architecture for Small-Batch Manufacturing

March 2, 1983
Author(s)
Charles R. McLean, Mary Mitchell, Edward J. Barkmeyer Jr.
The advent of fully automated, integrated, small-batch manufacturing control system has been slowed by several problems: the systems are complex, their development is costly, and the technology is not yet mature. But even more of a hindrance has been the
