Flammability Studies of New Cyanate Ester Resins

May 4, 1997
Author(s)
Jeffrey W. Gilman, Richard H. Harris Jr., James E. Brown
We have synthesized several new cyanate ester functionalized polystyrene polymers and copolymers. Poly(4-cyanatostyrene), PCS, poly(4-cyanatostyrene) "polymer grade", PCS-PG, poly(4-cyanatostyrene "novalak grade", PCS-NG, poly(4-cyanatostyrene-co

Book Review: Van der Waals and Molecular Science

May 1, 1997
Author(s)
Johanna Levelt Sengers, S G. Brush
Among 19th-century founders of statistical-molecular physics. Several such as Maxwell, Boltzmann, and Gibbs, have been the subject of book-length biographies and historical articles analysing their work. Comparatively little has been written in English

Computation of Fresnel Integrals

May 1, 1997
Author(s)
Klaus Mielenz
This paper summarizes the theory of Fresnel diffraction by rectangular and circular apertures with a view toward numerical computations. Approximations found in the earlier literature, and now obsolete, were eliminated and replaced by algorithms suitable

Electrothermal Simulation of an IGBT PWM Inverter

May 1, 1997
Author(s)
Alan Mantooth, Allen R. Hefner Jr.
A recently developed electrothermal network simulation methodoogy is used to analyze the behavior of a full-bridge, pulse-width modulated (PWM), voltage-source inverter, which uses insulated gate bipolar transistors (IGBT's) as the switching devices. The

Feature-Based Similarity Assessment of Solid Models

May 1, 1997
Author(s)
William Regli
This paper presents our initial efforts to develop a systematic approach for assessing the similarity of solid models based on how they will be manufactured. The goal of this work is to develop methods that, given a solid model representing the design of a

Manufacturing Process and Material Selection During Conceptual Design

May 1, 1997
Author(s)
Ronald Giachetti
It is important to consider every possible alternative during the design process since design decisions will determine the feasible manufacturing processes and the final product costs. Determining feasible combinations of material and manufacturing
