Scattering-Parameter Models and Representations for Microwave Mixers

January 1, 2005
Author(s)
Dylan F. Williams, Fabien Ndagijimana, Catherine A. Remley, Joel Dunsmore, Sean Hubert
We present straight-forward models and representations for RF and image mixers, and develop simple rules for transforming electrical problems involving mixers and signals at several frequencies into equivalent single-frequency problems. We show how those

Schematic Models of Molecular Self-Organization

January 1, 2005
Author(s)
K VanWorkum, Jack F. Douglas, Wolfgang Losert
Molecular self-organization is central to the formation of numerous biological structures and the emulation of this process through the creation of synthetic counterparts offers great promise for nanofabrication. Our approach to understanding the

Security Considerations for Voice Over IP Systems

January 1, 2005
Author(s)
David R. Kuhn, Thomas J. Walsh, S G. Fries
Voice over Internet Protocol (VOIP) refers to the transmission of speech across data-style networks. This form of transmission is conceptually superior to conventional circuit switched communication in many ways. However, a plethora of security issues are

Shop Data Model and Interface Specification

January 1, 2005
Author(s)
Charles R. McLean, Yung-Tsun Lee, Guodong Shao, Frank H. Riddick
This paper presents an information model that provides neutral data interfaces for integrating machine shop software applications with simulation. The model is presented using the Unified Modeling Language (UML) and the Extensible Markup Language (XML).

Smart Machining Systems: Issues and Research Trends

January 1, 2005
Author(s)
Laurent Deshayes, Lawrence A. Welsch, Alkan Donmez, Robert W. Ivester, David E. Gilsinn, Richard L. Rhorer, Eric P. Whitenton, Florian Potra
Smart Machining Systems (SMS) should be an important part of Life Cycle Engineering (LCE) since its capabilities are: producing the first and every product correct; improving the response of the production system to changes in demand (just in time)
