This paper discusses the suitability of two optimization methods for use in seismic retrofit location selection. The structure for analysis is modelled after a seven story RC structure in California, USA, built according to 1964 Los Angeles City Building Code. The OpenSees parallel computing software package is used to model the dynamic behaviour of a test structure. Past earthquake records are...

An appropriate solid waste disposal has been a major problem in municipal environment. The use of landfills is the most economical and environmentally acceptable method for the disposal of solid waste all over the world. The analysis of spatial data and consideration of regulation and accepted criteria are part of the important elements in the site selection. The aim of this paper is to show ho...

the gross calorific value (gcv) or heating value of a sample of fuel is one of the important properties which defines the energy of the fuel. many researchers have proposed empirical formulas for estimating gcv value of coal. there are some known methods like bomb calorimeter for determining the gcv in the laboratory. but these methods are cumbersome, costly and time consuming. in this paper, m...

An important assumption to maximize the performance of genetic algorithm is to study the convergence state of genetic algorithm. Genetic algorithm is a Mata-heuristic search technique; this technique is based on the Darwin theory of Natural Selection. The important property of this algorithm is that it has worked on multiple state of solution. This algorithm is work with some finite set of popu...
