According to availability based tariff the generating units are paid at higher rates for the unscheduled interchange they make to restore the frequency to nominal value of 50 Hz. Hence the generating units can earn more profit through unscheduled interchange. This paper compares the effect of primary and secondary controller in automatic generation control on dynamic change in generation and profit earned by generating units. A comparative study in terms of profit earning has been made between generating units with only primary controller or free governor mode and generating units with secondary or supplementary controller along with primary controller. This work also encourages the generating units to operate the units not only on free governor mode but also with supplementary controller which is still not commonly practiced in India.","PeriodicalId":109071,"journal":{"name":"2010 Annual IEEE India Conference (INDICON)","volume":"45 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122508720","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}

However, it is very difficult to identify these genes for disease diagnosis. In this regard, a new supervised gene clustering algorithm is proposed to cluster genes from microarray data. The proposed method directly incorporates the information of response variables in the grouping process for finding such groups of genes. Significant cluster representatives are then taken to form the reduced feature set that can be used to build the classifiers with very high classification accuracy. The effectiveness of the proposed method, along with a comparison with existing methods, is demonstrated on three microarray data sets based on predictive accuracy of the naive Bayes'classifier, the K-nearest neighbor rule, and the support vector machine.","PeriodicalId":109071,"journal":{"name":"2010 Annual IEEE India Conference (INDICON)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122787210","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 the proposed method, contemporary fuzzy logic is used to implement a relative pixel similarity value algorithm. The smoothness of each pixel is calculated in four directions by use of weighted similarity rules and is normalized to maximum gray level. In other words, image in three dimensional color spaces is mapped into one dimension. Accordingly, thresholding technique is used to find and highlight the edges associated with the image. The pixels lower than the threshold values are assumed to be edges. Thus with proposed method, edge pixels in a color image are detected simultaneously without any complex calculations such as gradient, Laplace and statistical calculations.","PeriodicalId":109071,"journal":{"name":"2010 Annual IEEE India Conference (INDICON)","volume":"31 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116450517","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 the Particle Swarm Optimization approaches have several advantages, they can still have drawbacks like local optimal trapping due to premature convergence(i.e. exploration problem). This paper proposes an improved PSO framework adopting a crossover operation scheme to increase exploitation capability of PSO. The study has been realized for control of a single area interconnected power system with IPSO optimized self-tuning PID controller. The comparison between a conventional Proportional-Integral (PI) controller and the proposed PSO based controller showed that the proposed controller can generate a better transient response for a step load change. For this application, MATLAB-Simulink software is used.","PeriodicalId":109071,"journal":{"name":"2010 Annual IEEE India Conference (INDICON)","volume":"45 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126257015","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}

For instance, an office goer often returns home in the evening (i.e., mobility is diurnal). While no existing research has studied direction-based diurnal mobility model which could be of immense importance to cellular operators, we formulate a Markov model for such movement and give a theoretical upper bound of cell boundary crossings (i.e., expected number of handoffs) by the user. We have theoretically calculated the number of handoffs based on our proposed mobility model and verified the result in a simulated environment. We find that a majority of inter-RNC/MSC handoffs [4] comes from only a few cells which should be made dual-homed by the operators for their cost reduction.","PeriodicalId":109071,"journal":{"name":"2010 Annual IEEE India Conference (INDICON)","volume":"90 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133371935","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 objective of the work is to generate a pencil beam with minimum Side Lobe Level (SLL) and maximum possible directivity. Excitation of individual array elements is computed using the algorithms. Dynamic Range Ratio (DRR) of current amplitude distribution is fixed at an optimum value. Phase of excitation distribution is fixed at zero degree.

Excessive high transmit power consumes more energy and increases internode interference significantly. While, low transmit power may cause network failure. Thus choice of optimal transmit power is one of the prime concern in such network. Optimal transmit power is the minimum power required to sustain the network connectivity while maintaining a predefined maximum tolerable Bit Error Rate (BER). In this paper, the effects of Rician fading are investigated on optimal transmit power, BER performance and energy consumption. Further impact of severity of Rician fading on WSN performance is also studied.","PeriodicalId":109071,"journal":{"name":"2010 Annual IEEE India Conference (INDICON)","volume":"6 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123891284","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}
