This paper is concerned with Hybrid Renewable Energy System (HRES) for energizing critical and sensitive loads in Information and Communication Technology (ICT) where the reliability is the first priority. As easy expandability and modularity are other objectives of the design, common ac bus structure is selected for this application. The ac power sharing is based on wireless control scheme, which...
Estimation of distribution algorithms, especially those using Bayesian network as their probabilistic model, have been able to solve many challenging optimization problems, including the class of hierarchical problems, competently. Since model-building constitute an important part of these algorithms, finding ways to improve the quality of the models built during optimization is very beneficial. This...
This paper is a review and evaluation of different on-line methods for diagnosing winding fault in induction motors presented in literature. Many methods can be found in literature; in some references, frequency analysis of motor signals such as current, speed, instantaneous power, Parkpsilas vector modulus and so on are introduced. Evaluation of negative sequence of current is also among the proposed...
Background estimation is one of the most challenging phases in extracting foreground objects from video sequences. In this paper we present a background modeling approach that uses the similarity of frames to extract background areas from the video sequence. We use a window over the frames history and compute the similarity between the selected frames of this window as a similarity window. The properties...
