TL;DR: The paper provides the results of preliminary research on the application of evolutionary computation to integrated structural design in which a complex design support tool automatically conducts both conceptual and detailed design.
Abstract: The paper provides the results of preliminary research on the application of evolutionary computation to integrated structural design in which a complex design support tool automatically conducts both conceptual and detailed design. In the paper, a brief overview of the state of the art in evolutionary computation and its applications to structural design is provided. Next, Inventor 2000 is described, a unique research and structural design tool developed by the authors at George Mason University that combines an evolutionary computation component with a system for wind forces analysis, and a system for the analysis, design and optimisation of steel structures. The paper also presents the results of four structural design experiments conducted with Inventor 2000. The objective of experiments was to investigate various forms of evolutionary computation as applied to structure design. Finally, the paper provides the initial research conclusions and recommendations for further research.

TL;DR: Disclosed as mentioned in this paper is a design tool and a method of fabricating a multi-layer printed circuit board, which utilizes the design tool to generate a set of cross section designs meeting the user specified parameters.
Abstract: Disclosed is a design tool and a method of fabricating a multi-layer printed circuit board. The method utilizes the design tool. The knowledge base means has both (1) printed circuit board cross sectional geometric parameter to transmission line parameter data and (2) "IF . . . THEN . . . " production rules for lamination, registration, circuitization, testability, test tools, and test procedures. These tools relate to manufacturability, cost, test development, second level packaging and printed circuit board. The printed circuit board begins with the user entering the printed circuit board design parameters and performance parameters into the input/output interface. Next, the knowledge base production rules are applied to the printed circuit board design and performance parameters to generate a set of cross section designs meeting the user specified parameters. The printed circuit board is then built up in accordance with one of the generated cross section designs.

TL;DR: In this paper, the authors present a design procedure for the practical design of RC wideband 90-degree phasedifference networks, which consists of many steps, each step being a relatively simple one.
Abstract: This paper presents a design procedure for the practical design of RC wide-band 90-degree phase-difference networks. The important part of the paper is the design procedure given in "cookbook" fashion with a numerical example to clarify it. This procedure consists of many steps, each step being a relatively simple one. This should make it a useful design tool for people without much background in network theory. A brief theoretical introduction is presented but this is far too sketchy to be of much use in understanding just what is behind the design procedure. Some practical hints on construction and alignment are given.
