Optimum Selection of Composite Material by Genetic Algorithm.

Optimum composite material design

— The microstructure identification problem is treated : given certain phases in given volume fractions, how to mix them in aperiodic cell so that the effective material constants of the periodic composite lie the closest possible to certain prescribed values ? The problem is studied for the linear conduction équation. It is stated in terms of optimal con trol theory ; the admissible micro geom...

OPTIMAL SELECTION OF NUMBER OF RAINFALL GAUGING STATIONS BY KRIGING AND GENETIC ALGORITHM METHODS

In this study, optimum combinations of available rainfall gauging stations are selected by a model which is consist of geo statistics model as an estimator  and an optimized model. At the  first,  watershed  is  approximated  to  several  regular  geometric  shapes.  Then  kriging calculates  the  variance &nbs...

Feature Selection Based on Genetic Algorithm in the Diagnosis of Autism Disorder by fMRI

Background: Autism Spectrum Disorder (ASD) occurs based on the continuous deficit in a person’s verbal skills, visual, auditory, touch, and social behavior. Over the last two decades, one of the most important approaches in studying brain functions in autistic persons is using functional Magnetic Resonance Imaging (fMRI). Objectives: It is common to use all brain regions in functional extracti...

Genetic optimization of two-material composite laminates

This paper describes the optimization of a composite laminate made from two materials. The use of two materials in the laminates design can offer improved designs, as it is possible to combine the desirable properties of the two materials. In this paper, we consider the use of graphite-epoxy, which has high stiffness properties, but is expensive, and glass-epoxy, which is not as stiff, but has ...
