Wind power has been widely considered and utilized in recent years as one of the most promising renewable energy sources. In the current research study, aerodynamic analysis of the upwind three-bladed horizontal axis turbine is carried out using blade element momentum theory (BEM), and a genetic algorithm (GA) is applied as an optimization method. Output power generation is considered as an obj...

4 Inferring the structure of an unknown network is a difficult problem of interest to researchers, academics, and industry. We develop a novel algorithm to infer nodes and edges in an unknown network. Our algorithm 6 utilizes sensors that have the capability to detect adjacent nodes and their labels, as well as and incident edges to the monitor. The algorithm places new sensors at the highest d...

We investigate the problem of placing monitors to localize node failures in a communication network from binary states (normal/failed) of end-to-end paths, under the assumption that a path is in normal state if and only if it contains no failed nodes. To uniquely localize failed nodes, the measurement paths must show different symptoms (path states) under different failure events. Our goal is t...

In this paper, a modified simulated annealing technique is proposed for simultaneous improvement of power quality and optimal placement and sizing of fixed capacitor banks in a modern distribution network. The later is supplying a mix of linear and nonlinear loads imposing voltage and current harmonics. Besides, they include integrated variable-speed wind turbines as distributed generation. The...

optimal capacitor placement, considering power system loss reduction, voltage profile improvement, line reactive power decrease and power factor correction, is of particular importance in power system planning and control. the distribution system operator calculates the optimal place, number and capacity of capacitors based on two major purposes: active power loss reduction and return on invest...

this paper presents a new control method for a three-phase four-wire unified power quality conditioner (upqc) to deal with the problems of power quality under distortional and unbalanced load conditions. the proposed control approach is the combination of instantaneous power theory and synchronous reference frame (srf) theory which is optimized by using a self-tuning filter (stf) and without us...

Due to the increasing use of Cloud computing services and the amount of energy used by data centers, there is a growing interest in reducing energy consumption and carbon footprint of data centers. Cloud data centers use virtualization technology to host multiple virtual machines (VMs) on a single physical server. By applying efficient VM placement algorithms, Cloud providers are able to enhanc...

In this paper, a novel multi-design thermal-aware dynamic placement planner for reconfigurable systems is presented, which targets transient temperature reduction. Rather than solving timeconsuming differential equations to obtain the hotspots, we propose a fast and accurate heuristic model based on power budgeting to plan the dynamic placements of a stream of design statically, while consideri...
