In a weakly coupled structural-acoustic problem, the boundary conditions may be composed by two conditions. One is a velocity boundary condition, which can be obtained from a dynamic structural analysis and the other is an acoustic impedance boundary condition. The acoustic impedance boundary condition is used for modeling acoustic absorbent behavior at boundaries proportional to the velocity d...

 This paper present unequal-sized facilities layout solutions generated by a genetic search program named LADEGA (Layout Design using a Genetic Algorithm). The generalized quadratic assignment problem requiring pre-determined distance and material flow matrices as the input data and the continuous plane model employing a dynamic distance measure and a material flow matrix are discussed. Computa...

The purpose of image optimization is that the salient region of image is stand out, and is layout an image met the demand. The existed image optimization method is summarized, and their advantages and disadvantages respectively analyzed. The improved visual attention model is described, and is used to detect the salient region of image. The parameters of image optimization are calculated by the...

Presents article is deal with optimization of the fixture for end milling process, the most important objective being the minimization of work piece deformation by changing the layout of fixture elements and the clamping forces. The main objective of this work has been the optimization of the fixtures Work piece deformation subjected to clamping forces for End milling operation. The present ana...

This paper presents a new method to extract functionally equivalent structures from logic netlists. It uses a fast functional regularity extraction algorithm based on structural equivalence. The goal of the proposed algorithm is the speedup of logic optimization of large circuits by reusing functionally equivalent structures of the design. It is particularly suited for circuits containing a lar...

With the advent of deep sub-microntechnologies,interconnectloads and delays are becoming dominant. Consequently, the currently used design ow of iterativelyperforming logic synthesis with statistical wire-load models, doing placement & routing, extracting par-asitics, and using them back in the synthesis tool runs into serious timing convergence problems. Layout-driven synthesis has become the ...

the dynamic facility layout problem (dflp) is the problem of finding positions of departments onthe plant floor for multiple periods (material flows between departments change during the planning horizon)such that departments do not overlap, and the sum of the material handling and rearrangement costs isminimized. in this paper a new optimization algorithm inspired from colonizing weeds, invasi...

Fairs and expositions are nowadays fundamental tools for providing industrial exhibits and demonstrations. According to the International Association of Fairs & Exposition (IAFE), over 3 200 fairs are currently held in North America each year. The European Major Exhibition Centres Association (EMECA) estimates that more than 36 million visitors and upwards of 330 000 exhibitors take part in rou...

The RICH detector in CBM shall provide electron identification together with the TRD detectors for the measurement of low-mass vector mesons and charmonium in the di-electron decay channel. Both observables are considered key probes for the study of compressed baryonic matter in heavy ion collisions. A RICH design based on first general considerations has been developed and studied in detector ...

This article presents an optimization model of the quantifiable aspects of architectural floorplan layout design, and a companion article presents a method for integrating mathematical optimization and subjective decision making during conceptual design. The model presented here offers a new approach to floorplan layout optimization that takes advantage of the efficiency of gradient-based algor...
