Integrating renewable resources into the electrical systems of marine vessels achieves dual goal diversifying energy and reducing greenhouse gas emissions. The presence intermittent sources sudden nonlinear load changes can cause frequency deviations in isolated hybrid microgrids. To address this issue, paper proposes a conventional PID (proportional–integral–derivative)-controller-based LFC (l...

Task scheduling is heart of any grid application which guides resource allocation in grid. Heuristic task scheduling strategies have been used for optimal task scheduling. Heuristic techniques have been widely used by the researchers to solve resource allocation problem in grid computing. In this paper, we classify heuristic task scheduling strategies in grid on the basis of their characteristi...

Techniques for composing architectural specifications are emerging in order to facilitate software architecture evolution. However, there is little empirical understanding on whether such techniques scale when they are used to express different types of architectural changes. This paper presents a first comparative evaluation of two significantly-different composition techniques for architectur...

While the exploitation of problem structure by heuristic search techniques has a long history in AI (Simon, 1973), many of the advances in constraint-directed scheduling technology in the 1990s have resulted from the creation of powerful propagation techniques. In this paper, we return to the hypothesis that understanding of problem structure plays a critical role in successful heuristic search...

Traditional optimization techniques such as Dynamic Programming(DP), Linear Programming(LP), and MixedInteger Programming(MIP) have been used to solve complex optimization problems in many diverse fields. Shortcomings of these classical techniques and the rapid development of affordable, powerful computing technology have led to the creation of new classes of heuristic-based optimizing techniqu...
