  Public sensitivity to environmental issues in the economic dispatch is also impressive. In this case it is necessary to consider the costs of pollution in the economic dispatch. Before the introduction of the concept of power system security, the subject of economic load dispatch normally focused on economic aspects rather than security of the system. Today, with the expansion of the power grid and system load, combination of stability and economic load dispatch indices has become a critical necessity. This article will consider the issue of solving the economic dispatch of power plants considering the emissions and security indices of the network. Using penalty functions, system security indices are added to the objective function of economic load dispatch problem. Since fuel costs and emission reduction targets are relatively contrasting, problem solving of economic load dispatch and emission reduction leads to a multi-objective optimization problem. Given the complexity of objective functions and necessity of the considering the practical constrains of power plants operation and security indices reveal more than ever the need to use efficient methods to optimize. In this article Multi Objective Harmony Search algorithm (MOHS) has been used to solve the problem. The results show that MOHS algorithm is excellent for convergence and accuracy compared to other employed methods. The proposed testing system used to solve the problem is IEEE test system with 10 power generation units, 39 bus and 46 transmission line. Manuscript profile

  In network-on-chip implementation, mapping can be considered as an important step in application implementation. The tasks of an application are often represented in the form of a core graph. The cores establish a link between themselves using a communication platform and often the network on the chip. For finding proper mapping for an application, developers have proposed various algorithms. In most cases, due to the complexity, exact search methods are used to find the mapping. However, these methods are suitable for networks with small dimensions. As the size of the network increases, the search time also increases exponentially. This article, from the perspective of a heuristic approach, uses the harmony search method to decide when to connect cores to routers. Our approach uses an improved version of the harmony search algorithm with a focus on reducing power consumption and delay. Algorithm complexity analysis reveals a more appropriate solution compared to similar algorithms with respect to application traffic pattern. Compared to similar methods, the algorithm achieves 39.98% less delay and 61.11% saving in power consumption. Manuscript profile
