This algorithm that is based on a socio-politically inspired optimization strategy has shown good convergence rate to achieve global optimum for different optimization problems. In a deregulated electricity market, reactive power suppliers as one of six ancillary services are eligible for financial compensation. In this paper, a reactive power market that is decoupled from the active power market has been solved using the ICA. Minimizing energy losses and total payments to reactive power providers by the system operator are considered as the objectives of the introduced reactive power market. The corresponding optimization problem is a non-convex Mixed-Integer Non-Linear Programming (MINLP) problem. Here, an algorithm is introduced that uses the ICA to change the MINLP problem to a series of NLP sub problems. The IEEE 30-bus test system is used to demonstrate some aspects of the application of the ICA on the reactive power market problem. The results are compared with those obtained by Genetic Algorithm (GA) showing that the ICA convergence rate is more than GA.","PeriodicalId":308726,"journal":{"name":"20th Iranian Conference on Electrical Engineering (ICEE2012)","volume":"37 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-05-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125094678","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This attack affects functionality of network by dropping data packets. Black hole attack operates based upon two different phases; first, advertising fake routes containing attacker node. Second, dropping received data packets. When it comes to route advertisement phase, operation of this attack in reactive protocols can be classified into two categories. Advertising fake routes in response to route request (RREQ) packets, and advertising according to route reply (RREP) packets. In related works, Black hole attack has been evaluated and analyzed based on creating fake RREPs in response to received RREQ packets. In this paper, however, a novel more destructive attack named Deep Black hole is introduced and evaluated. This attack advertises fake RREPs more strongly than previous ones. Evaluation of network parameters has been performed related to DSR protocol in NS-2. Simulation results represent that Deep Black hole, compared to ordinary Black hole and selfish nodes, is more damaging and leads to network denial of service. This attack results in a decrease in the number of network routing packets and end-to-end delay especially compared to selfish nodes.","PeriodicalId":308726,"journal":{"name":"20th Iranian Conference on Electrical Engineering (ICEE2012)","volume":"30 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-05-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122211194","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Among the various methods used in BCI area, motor imagery (MI) is the most popular and the most common one due to its the most natural way of communication for the subject. Some software applications are used to implement BCI systems, and some toolboxes exist for EEG signal processing. In recent years virtual reality (VR) technology has entered into the BCI research area to simulate the real world situations and enhance the subject performance. In this work, a completely MATLAB-based MI-based BCI system is proposed and implemented in order to navigate into a virtual environment. In addition, a variety of features types were employed to select the best ones in the proposed system with the use of linear discriminant analysis (LDA) classifier through some interactive graphical user interfaces (GUIs). The results show the feasibility of the proposed BCI system in the subject training with or without feedback and even navigation into a virtual home.","PeriodicalId":308726,"journal":{"name":"20th Iranian Conference on Electrical Engineering (ICEE2012)","volume":"22 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-05-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"117032749","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Although THP method has a number of advantages in MIMO systems, however, it staffers from some drawbacks including modulo loss, shaping loss and power loss. In the THP technique, due to modulo operation, the transmitted symbols are distributed over a bounded region which is larger than the original constellation. Hence, the transmitted power will be increased. It is shown that the transmitted power can be reduced significantly by tilting or rotating the original constellation and hence, some of the power loss are recovered. In this paper, a tilted constellation method is developed for MIMO-ZF-THP and MIMO-MMSE-THP systems and in both centralized and decentralized (multiuser) scenarios. In the proposed methods, each transmit antenna uses a different rotating angle individually to tilt the constellation. The simulation results show that the proposed method outperforms the conventional MIMO-THP technique. In addition it is shown that the performance gain in the decentralized MIMO-THP scenario is more than the centralized MIMO-THP.","PeriodicalId":308726,"journal":{"name":"20th Iranian Conference on Electrical Engineering (ICEE2012)","volume":"23 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-05-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128641382","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
