In this paper, the impact of Stone-Wales defect on a Zigzag Graphene Nano-ribbon has been investigated for ferromagnetic and anti-ferromagnetic states. The Magnetic Resistance is calculated by applying Stone-Wales defect in the center of Graphene Nano-ribbons. The simulations are based on DFT method. The simulation results show that, by applying Stone-Wales defect, the bandgap increases in comparison to the ideal state, the conductivity decreases, and so does the current, and as a result of that, the Magnetic Resistance, at voltages below 0.5 V, decreases in comparison to the ideal state. At voltages above 0.5 V, the Magnetic Resistance increases in comparison to the ideal state. Also Magnetic Resistance can get negative values and reaches 650% at 1 V. The large tunable Magnetic Resistance of graphene nano ribbons is attractive to device applications.","PeriodicalId":168295,"journal":{"name":"2015 2nd International Conference on Knowledge-Based Engineering and Innovation (KBEI)","volume":"29 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126821006","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}

The new structure has a profound effect on the entire system. Now, power networks can deploy computing technologies to achieve new level of performance and efficiency. Game theory is a mathematical tool for modeling distributed multi-agent systems. There are game theoretic approaches for studying and solving smart grid issues. Important issues have been studied with game theory include demand side management, load shifting and dynamic energy price. Different authors have used different types of games and payoff functions. In this paper, we categorize most important issues and subjects in both game theory and smart grid. Also, we have a comprehensive review of articles which propose game theoretic approaches in the field of smart grid.","PeriodicalId":168295,"journal":{"name":"2015 2nd International Conference on Knowledge-Based Engineering and Innovation (KBEI)","volume":"7 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121220963","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}

Solving this problem by using meta-heuristic algorithms to get good quality solution for average data takes a few minutes and for large data lasts for several hours. In this paper, to reduce the time to solve the problem of parallel genetic algorithm based on GPU (Graphics processing unit) is used. In addition, due to the problem of premature convergence of genetic algorithms, to improve results, some changes are applied on genetic algorithm. The results show that the proposed algorithm based on GPU gets more high-quality solutions in much less time than genetic algorithm based on CPU to solve the problem of QAP.

WSNs measure environmental conditions like temperature, sound, pollution levels, humidity, wind speed and direction, pressure, etc. Sensors are usually attached to microcontroller and are powered by battery. Energy consideration is a critical issue for designing routing protocols. Routing techniques are the most important issue for networks where resources are limited. LEACH is one of the first hierarchical routing approaches for sensor networks. Most of the clustering algorithms are derived from this algorithm. In this paper we propose an improvement on the LEACH Protocol. In our proposed algorithm, Network logically divided into 4 zone. In first round for select CH the node that close to center of every zone forward its location to BS. Then BS select nodes that are closer than other node to center of regions. In addition, the residual energy of each node is also considered. We evaluate LEACH, PR-LEACH and Energy-Zone LEACH (EZ-LEACH) through simulations using NS2 simulator which shows that LR-LEACH performs better than LEACH and PR-LEACH protocols.","PeriodicalId":168295,"journal":{"name":"2015 2nd International Conference on Knowledge-Based Engineering and Innovation (KBEI)","volume":"5 18","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"113955817","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}

In this technique, appropriate signals are added to the main baseband input signal to reduce the nonlinearity of the PA. The non-linear relationship between input and output of an RF PA is analyzed and optimum values for the injection signals at the intermodulation frequencies are obtained. In addition, a high-speed low-cost MATLAB-FPGA interface is designed that can be used both in the training and testing phases of the system. Simulation results indicate that the proposed technique is capable of remarkably reducing spectral regrowth in adjacent channels for different non-constant envelope signals. Using a QPSK signal, the spectral regrowth and ACPR of the PA are decreased by 20dB and 26dB, respectively.","PeriodicalId":168295,"journal":{"name":"2015 2nd International Conference on Knowledge-Based Engineering and Innovation (KBEI)","volume":"211 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124150731","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}

On the other hand, costumers are willing to buy their requirements more convenient by allocating less effort in energy and money expenditure and be aware of special offers to keep them in frugality. Consequently, we came up with an idea to invent \"An Intelligent Interactive Marketing System based-on Internet of Things (IoT)\" which helps these two groups to interact with each other and meet their needs in the best way. By using this system, costumers are able to get an application from the server of the shopping center (that is prepared by the Service Provider (SP)) while entering there to interact with this system. This application offers welcoming and questioning about costumer's favorites to recommend an effective orientation to the exact place to buy stuffs and in addition to aware costumer about its availability or not in that mall, get some services or get aware of special offers even though he/she doesn't have any tendency toward buying. In addition to the system mentioned above, by using the IoT, all stocks in stores can be dispatched to the server for the better performance and real time responding of our system.
