Geometric programming : theory and application by Richard James Duffin( Book )

27 editions published between 1967 and 1972 in 3 languages and held by 586 WorldCat member libraries worldwide

This report is a brief summary of progress by the authors and their associates in their research on the reduction and decomposition of large generalized geometric programming problems and their application for the period 1 March 1974 through 28 February 1975. The problems under study concern (1) the optimal design and operation of hydraulic pipelines, transportation networks, and mechanical and electrical devices, (2) the optimal location of facilities, (3) the analysis and optimal design of structures, and (4) certain aspects of chemical equilibrium, regression analysis, and optimal control. To effectively and efficiently obtain solutions to these problems when stated in geometric programming formulations, methods that ameliorate the complexity of the total system are being developed. These methods center around the ideas of 'decomposing' the total system into smaller subsystems and 'reducing' the dimensionality of the overall system. This summary provides an outline of the most recent results in this research project and provides a listing of publications in which additional detail on the research can be obtained

The AEMS Project in Applied Mathematics at Carnegie-Mellon University( Book )

2 editions published between 1971 and 1982 in English and held by 2 WorldCat member libraries worldwide

This is a record of a research project in applied mathematics at Carnegie-Mellon University. The project is called 'Analysis of Electrical and Mechanical Systems' or AEMS for short. The aims of AEMS are threefold: (a) to apply mathematical analysis to treat new problems arising in science and technology; (b) to develop new mathematical concepts and structures using facets of science and technology as models; and (c) to help students start a career in the interesting area of applied mathematics.

Network synthesis through hybrid matrices by Richard James Duffin( Book )

2 editions published in 1964 in English and held by 2 WorldCat member libraries worldwide

It is shown that the hybrid parameter matrix of a passive n-port network is a positive real matrix function. The hybrid, chain and immittance parameter matrices all have the same degree. The concept of combinatorial equivalence is extended from the linear programming field to network synthesis. An n-port extension of the Brune synthesis procedure is given. A novel concept of degree enumeration is given. (Author)
