this paper investigates the islands formation in initial stages of restoration process in blackout condition and studies the impacts of islands number variation on the process execution. in addition, a method is proposed to determining each island optimal boundaries. then the effects of transmission lines thyistor controlled series compensators (tcsc) to facilitate restoration process and impro...

in this study, the optimum combination of major factors affecting the acceptability of whey-based ricotta cheese i.e. fat at three levels (0, 5, 10%), salt at three levels (0, 1, 2%), and starter culture at two levels (0, 3%) was determined in a complete randomized design method with a factorial experiment. ricotta cheese trials made by mixing whey and milk in a ratio of 5:1 were then organ...

The main purpose of the present work is to investigate the impact of soil-structure interaction on performance-based design optimization of steel moment resisting frame (MRF) structures. To this end, the seismic performance of optimally designed MRFs with rigid supports is compared with that of the optimal designs with a flexible base in the context of performance-based design. Two efficient me...

In the paper we examine the problem of optimization of parameters of technological process for obtaining a molten pool with a needed depth on the surface of the metal sample under the thermal local laser treatment. A mathematical model of heat distribution during thermal laser treatment is simplified to a linear problem of heating a half-space, that can be used for plates of finite thickness. D...

Recently sample-path methods have been successfully used in solving challenging simulation optimization and stochastic equilibrium problems. In this paper we deal with a variant of these methods to solve stochastic optimization problems with stochastic constraints. Using optimality conditions, we convert the problem to a stochastic variational inequality. We outline a set of sufficient conditio...

Optimization of turning process is a non-linear optimization with constrains and it is difficult for the conventional optimization algorithms to solve this problem. The purpose of present study is to demonstrate the potential of Imperialist Competitive Algorithm (ICA) for optimization of multipass turning process. This algorithm is inspired by competition mechanism among imperialists and coloni...
