the present study sets out to integrate the performance-based seismic design approach with the connection topology optimization method. performance-based connection topology optimization concept aims to simultaneously optimize the size of members and the type of connections with respect to the framework of performance-based seismic design. this new optimization concept is carried out for unbrac...

In modern machining process, optimization technique is used to find the optimal values of input parameters and the effect of those parameters on response variables. If response parameters are more than one, Taguchi method of optimization may give different set of optimal levels for each response. In the present study, Taguchi-grey relational approach based multi response optimization has been u...

To date the primary focus of most constrained approximate optimization strategies is that application of the method should lead to improved designs. Few researchers have focused on the development of constrained approximate optimization strategies that are assured of converging to a Karush-Kuhn-Tucker (KKT) point for the problem. Recent work by the authors based on a trust region model manageme...

Hydrometallurgical leaching process has been identified as a viable procedure for recovering metals of value from their matrices. The optimization zinc recovery sphalerite in nitric acid solution was carried out this study. Central Composite Rotatable Design (CCRD) Response Surface Methodology (RSM) and Particle Swarm Optimization (PSO) tool matlab were deployed the studies. RSM modeling gave o...
