It is a challenging problem to the power engineers to detect these faults at an early stage. If these incipient faults are not detected at their inception, they would develop into more severe faults that may result in damage to the transformer. In this paper a physical model of a multiwinding power transformer of 100 MVA, 138/13.8 KV is simulated in a power system using MATLAB/SIMULINK software. Different percentages of turns such as 1%, 3%, 5%, 10%, 15%, and 25% are shorted on primary and secondary sides of the multiwinding transformer to measure the terminals current. The change in the terminals current during fault incidence (inter turn fault) is negligibly small. In order to experience significant changes, negative sequence currents are extracted using symmetrical component approach. The percentage changes in magnitudes of negative sequence currents (%MAG) and the corresponding phase shifts (PS) that occur in the transformer during fault incidence period are evaluated and they are fed as inputs to fuzzy logic. Here fuzzy logic is employed not only to monitor the condition of the transformer but also to improve the sensitivity of the proposed scheme. The two variables (%MAG& PS) are fed as inputs to fuzzy logic. Depending on the data obtained, the inputs are assigned with three membership functions each namely low, medium, and high. A fuzzy inference engine is built with nine fuzzy rules based on the knowledge gained from the system behavior. Here the process of defuzzification is carried out by using centroid calculation method. The output variable is named as transformer condition (TC), Which is assigned with three membership functions such as Incipient fault (IF), Minor fault (MF), and Severe fault (SF).","PeriodicalId":403563,"journal":{"name":"2014 International Conference on Science Engineering and Management Research (ICSEMR)","volume":"35 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122019086","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}

Micro finance includes savings accounts, insurance products and credit provided to low income unbanked people to increase their economic status in the society. Micro-insurance is a shelter against the hazards of low-income people in exchange of a premium in proportion with the possibility and cost of risk associated. A micro-insurance policy may be a general or a life insurance and done through Non-Government organizations, Self-help groups and Micro-finance institutions. Life Insurance Corporation of India has three micro-insurance products namely, Jeevan Madhu, Jeevan Mangal and Jeevan Deep. The main objective of this study is to find out the need for micro insurance among unbanked people and to find out whether micro insurance helps the unbanked people to enhance their livelihood. Simple random sampling is adopted for the collection of primary information from 150 respondents from Tiruchirapalli town by administering a questionnaire. The data collected were analyzed with the help of statistical tools like Percentage analysis and Chi-square test using SPSS package. The respondents revealed that joining in SHG linked LIC results in the overall socio-economic empowerment in their individual lives. The study concludes that the LIC should create more awareness among unbanked people to improve their standard of living by bringing them under the beneficial umbrella of micro insurance.","PeriodicalId":403563,"journal":{"name":"2014 International Conference on Science Engineering and Management Research (ICSEMR)","volume":"7 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128866781","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 aim is to develop an efficient personal identification system to provide secure access for legitimate users which is a challenging task. In order to avoid these problems, the use of biométrie traits reliably provides efficient and effective solutions. Though unimodal biometrics faces various issues such as non-universality, distinctiveness, spoof attacks, noise in sensed data, intra-class variations. To overcome these issues, Multimodal biometrics based personal identification system is developed using Soft Computing Techniques. The biométrie traits such as fingerprint, palmprint and finger knuckle print are used for recognition system. Artificial Neural Networks (ANN) and Genetic Algorithm are used for this purpose. The Haralick features are used for the recognition system. The proposed system achieves excellent identification rate and higher user acceptability. Thus the proposed system reduces the FRR rate.","PeriodicalId":403563,"journal":{"name":"2014 International Conference on Science Engineering and Management Research (ICSEMR)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129305213","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 effects on the structural, compositional and optical properties are discussed. Simple solution- thermal method is suitable and more economical for large-scale production. The powder X- ray diffraction pattern of the equal amount of divalent metal ions mixed ZnO samples shows the mixed phases of the respective divalent metal oxides apart from the wurtzite ZnO peaks. Scanning electron microscope (SEM), Fourier Transform Infrared spectroscopy (FTIR), Thermo gravimetric analysis (TGA) and UV-visible spectrophotometry were employed to characterize the samples. From the study of FTIR spectroscopy, the Zn-O bonding is shifted towards the higher wave numbers on mixing Ni, Pb and Cu oxides with the ZnO nano particles. The absorption band of ZnO/NiO, ZnO/PbO, and ZnO/CuO mixed oxides are distinctly broadened and red-shifted indicating the strong interfacial interaction between ZnO and mixed oxides. The band gap of the nano particles can be tuned in the range of 2.7-3eV by the addition of divalent metal ions.","PeriodicalId":403563,"journal":{"name":"2014 International Conference on Science Engineering and Management Research (ICSEMR)","volume":"45 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122792791","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}
