a new approach for propulsion system layout that increases power and enhances the efficiency of submarine propulsion system is proposed.using our method,the efficiency and power of the system enhances without increasing volume and weight. this layout improves the performance compared to the usual layout, which employs double-armature motors in cruise speed where efficiency is more critical. thi...

This paper experiments application of different heuristic approaches to a real facility layout problem at a furniture manufacturing company. All the models are compared using AHP, where a number of parameters of interest are employed. The experiment shows that formal layout modelling approaches can be effectively used real problems faced in industry, leading to significant improvements.

We propose a fast algorithm for the transistor-chaining problem in CMOS functional cell layout based on Uehara and van Manuscript received January 4, 1989; revised May 31, 1989. This work was supported in part by ERSO under Contract SF-C-010-1 and by the Cleemput’s layout style [lZ]. Our algorithm takes a transistor-level circuit schematic and outputs a minimum set of transistor chains. Possibl...

Spectral methods are naturally suited for dynamic graph layout, because moderate changes of a graph yield moderate changes of the layout under weak assumptions. We discuss some general principles for dynamic graph layout and derive a dynamic spectral layout approach for the animation of small-world models.

| A new approach for the minimum area oorplanning is proposed where the shape of every module can vary under the constraint of area and oorplan topology. Simulating the air-pressure mechanics, the algorithms iterate to improve the layout to decide the shapes and positions of modules. It is proved that the layout approaches the optimal layout each step by the measure of energy which is de ned by...
