In the proposed work an effort is made to overcome this shortcoming by taking the advantage of greater wind speeds at higher elevations by bringing into use the heights of the high rise structures .e.g. Residential and shopping complexes, Mobile communication towers etc. As the electric power generated by a wind turbine increases in a cubic order with wind speed so the heights of relatively taller buildings and towers, in the order of tens of feet, is one of great significance. The prototype system, consisting of a small wind turbine interfaced with PC, deployed at a test site was used for monitoring the wind conditions as well as the actual electric power generation on a small scale. The data acquired thus along with actual wind profile recorded at the site over a period of time from other sources were further used in the simulation of a system harnessing power at different heights. A budgeting software was also used in order to keep track of the prices incorporated and financial assessment of the system. While keeping structural stresses within safe limits, the ultimate electrical power generated can be of such orders that it can be used to partly fulfill the running demand of a residential building.","PeriodicalId":325890,"journal":{"name":"2014 International Conference on Emerging Technologies (ICET)","volume":"21 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125950413","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 practice test case generation is the most laborious and resource consuming process in software testing hence generating test data for object-oriented programs is even more challenging and effort demanding. Object-oriented evolutionary testing aims at automating test case generation process using evolutionary strategies like Genetic Algorithm. Evolutionary testing gives a helping hand to the software testers to speed up the process and to reduce the amount of project resources. The existing approaches provide sound platform to the researchers to take the work further to meet the challenges that object-oriented paradigm has introduced. One of the limitations in existing approaches is that they combine branch distance of object's state variables with local variables that leaves no guidance for the search process whether object has gained desired state or not. We propose a state-based fitness function for the evolutionary testing of object-oriented programs that can solve object's state problem by evaluating object's state as an independent segment of overall test case fitness. Our initial experiments show that by separating object's state evaluation, search gets better guidance to prevent object's state problem.","PeriodicalId":325890,"journal":{"name":"2014 International Conference on Emerging Technologies (ICET)","volume":"126 1-2 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132240316","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}

Multimedia data such as audio, video and image transfers over the internet is open and insecure. Security is required for storage and transmission of digital images to avoid from unauthorized entities. A number of encryption schemes have been developed for security of multimedia data over insecure channel. So, there is a real need to compare encryption schemes that which technique is better for multimedia application. This paper presents the estimation for the good image encryption algorithm. Chaos based image encryption algorithm are used now a days because of better security and good performance. Behaviour of chaotic system is nonlinear, deterministic and sensitive to initial condition. A number of parameters, like correlation coefficient, information entropy, compression friendliness, number of pixels change rate, average intensity and unified average change intensity etc., are used to check the quality of cipher-text image. This work is review of two image encryption schemes, namely Compression Friendly Encryption Scheme (CFES) and Chaos Based Encryption Scheme (CBES).","PeriodicalId":325890,"journal":{"name":"2014 International Conference on Emerging Technologies (ICET)","volume":"59 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126346716","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}

Due to the ill-posed nature of EIT inverse problem, EIT bears poor spatial resolution and behaves non-linearly in nature. Point spread function (PSF), which is calculated over the whole domain as responses to a small circular anomaly moving around the entire domain, is a characteristic parameter to estimate the performance of imaging systems. In order to analyze the quality of EIT reconstructed image, PSF is employed in this work. PSF incorporates the key imaging attributes, comprising amplitude response, resolution, position error, shape deformation and ringing effect. This paper presents a numerical study on the use of PSF for static and dynamic EIT image reconstruction. The static image reconstruction is done using the modified Newton Raphson (mNR) algorithm whereas the dynamic image reconstruction is done with extended Kalman filter (EKF). A detailed analysis of the performance of mNR and EKF has been carried out based upon on the imaging attributes gathered using the said algorithms. The results are convincing and provide a fresh perspective to use the PSF in order to analyze the performance of EIT image reconstruction.","PeriodicalId":325890,"journal":{"name":"2014 International Conference on Emerging Technologies (ICET)","volume":"27 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115301786","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}

Users want their queries to be more relevant to the documents. For this purpose, the idea of proximity is utilized where close query terms in the document show high proximity and hence the document is likely to be more relevant. But almost every retrieval function (e.g., BM25) uses bag-of-words technique, thus ignoring the importance of proximity. In this paper, we find such short sentences (sub-sentences) or group of words that are made by distinct words or terms on their first occurrence in the documents to calculate the proximity and subsequently incorporate it into a retrieval function to improve the ranking of the documents. We have shown that there are significant numbers of short sentences formed by distinct words that can be used to exploit proximity and phrase search. Furthermore, turning the non-positional (record level) inverted index into partial-positional inverted index by utilizing distinct terms (UDT), the UDT partial-positional inverted index has been separated from the full positional (word level) inverted index to calculate proximity among the distinct terms efficiently. As calculating proximity with full positional inverted index is complex and computationally expensive, the proximity with the UDT partial-positional inverted index can be computed easily and efficiently. Experiments on various data sets have shown that the proposed approach has improved the precision of the documents.","PeriodicalId":325890,"journal":{"name":"2014 International Conference on Emerging Technologies (ICET)","volume":"73 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115961568","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}
