The compressed file contains only ASCII characters. The proposed scheme also allows the decompression technique where the original ECG waveform can be exactly reconstructed and retrieve patient's identification from the ECG signal. The whole module has been applied to various ECG data of all the 12 leads taken from PTB diagnostic database (PTB-DB) of physioNet (www.physionet.org) and gives a highly compressed result that can be stored using far less digital space without distorting important ECG characteristics which are essential for proper medical diagnosis. Moreover, the compression, embedding, decompression and retrieving of data are achieved in a series of sequential, simplistic logical processes that can be easily executed. It is observed that the proposed algorithm gives a high compression ratio (CR=7.3593, an excellent Quality Score (QS=1362) and very low difference between original and reconstructed ECG signal (PRD=O.0054).","PeriodicalId":265072,"journal":{"name":"Proceedings of the 2014 IEEE Students' Technology Symposium","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2014-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128012939","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 in-house developed accelerometer consists of a Silicon on Insulator (SOI) based comb drive structure integrated on a PCB with capacitance signal conditioning ASIC. A simple PI type controller designed using basic components like resistors, capacitors and op-amps are externally incorporated. The self test arrangement in MEMS structure has been successfully utilized for applying feedback voltage to operate the device in a closed loop configuration. The proposed scheme is shown to be a simple and cost effective approach for driving similar open loop MEMS accelerometers in a closed loop configuration. Further, the experimental results for both open loop and closed loop arrangement are shown to agree well with their corresponding simulated responses.","PeriodicalId":265072,"journal":{"name":"Proceedings of the 2014 IEEE Students' Technology Symposium","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2014-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126194697","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 SSSC is mainly GTO based which can control different parameters of power system. A supplementary damping controller for a SSSC is designed for power system dynamic performance enhancement. The lead-lag structure of damping controller is used for the damping of power system oscillation. The proposed controllers design problem is formulated as an optimization problem. The Gravitational Search Algorithm (GSA) is employed to optimize the damping controller parameters. To demonstrate the effectiveness of the proposed adaptive SSSC based supplementary damping controller, computer simulations are performed on a power system considering a single machine infinite bus installed with SSSC. The Simulation results are presented and these results are compared with a conventional method of tuning the damping controller parameters. This will analyze the effectiveness and robustness of the proposed design approach.","PeriodicalId":265072,"journal":{"name":"Proceedings of the 2014 IEEE Students' Technology Symposium","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2014-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129382396","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}

Everyday large volume of data is being generated. For example, flight navigation data, health care monitoring data, social media data, video surveillance data etc. This data contains rare events or anomalous points that needs to be found out-for example less than 2 % of all visitors who visits Amazon website make a purchase. Thus anomaly detection problem can be interesting due to business perspective, security, maintenance etc. The problem becomes challenging because of noise, heterogeneity, high dimensionality of the data. This paper studies a robust algorithm, based on support vector data description, for anomaly detection. We perform extensive experiments on real data coming from nuclear power plant to empirically demonstrate the effectiveness of the algorithm as well as finding anomalies in the data set. We also discuss extensions of the algorithm to find anomalies in high dimension and non linearly separable data.","PeriodicalId":265072,"journal":{"name":"Proceedings of the 2014 IEEE Students' Technology Symposium","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2014-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121356915","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}

Nowadays, Coated Conductors (CCs) are widely used for novel design of SFCL for such applications. In this paper, comparative study on the operational characteristics of Resistive-SFCL based on BSCCO and YBCO Coated Conductors under fault condition is analyzed for an 110kV/9kA network. Also Electro-thermal Model of Coated Conductor is studied in MATLAB software. To verify the effectiveness of the proposed Resistive-SFCL, several case studies of Coated Conductors have been carried out in MATLAB. The results show the choice of optimal configuration of CCs as SFCL which effectively improves the thermal stability and current limiting characteristics under fault condition in the network.","PeriodicalId":265072,"journal":{"name":"Proceedings of the 2014 IEEE Students' Technology Symposium","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2014-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114947011","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 notch filter designed at 10.5 GHz eliminates the first interfering tone. When the second interference appears at the input of this notch filter the response is modified and its fails to remove the first interference because the null point of the response gets shifted upwards under the action of the second interference. The dc shift of the minimum of the response has been calculated and measured when the second interference is 520 MHz below the first interference.

The illiterate people like - farmer, shopkeeper etc. are unable to take the advantages of the ICT revolution. According to the UNESCO report, population of such people in the globe is 64% who are unable to use the technology either language or technical barrier. Moreover the percentage (76%) must be increased in the context of developing countries. The essential agriculture information is very useful to a farmer for taking effective decision thus we proposed to develop an iconic interface which is integrated with speech based interaction in Indian languages. The proposed interface is critically evaluated with the farmer from different states of India. The evaluation results proved the effectiveness of the proposed interface.","PeriodicalId":265072,"journal":{"name":"Proceedings of the 2014 IEEE Students' Technology Symposium","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2014-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133660222","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}

One of the major challenges in such technique is to validate the result as the actual or correct results are often not known or difficult to know. In this context, three commonly known evaluation measures are precision, recall and f-measure. All these indices are external validity indices as they all need gold standard data. But in Bibliographic databases like DBLP, Arnetminer, Scopus, Web of Science etc., obtaining golden standard is very difficult for each entity. So, there is a need to use some other metrics to evaluate the performance on Bibliographic data. In this paper, a novel scheme based on internal validity index is used to evaluate the performance of entity name disambiguation algorithm. Several distance measures are used here to compute the similarity between two records. These functions are then incorporated in the definitions of internal validity indices.","PeriodicalId":265072,"journal":{"name":"Proceedings of the 2014 IEEE Students' Technology Symposium","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2014-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"117293710","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}
