In Existing system, the Hybrid depth generation algorithm has three depth cues for depth estimation: motion information, linear perspective, and texture characteristics. To find the edge detection they are using a sobel operator. We propose a canny edge detection algorithm instead of sobel operator to find the accurate edge detection; this edge detection algorithm is used to reduce the amount of data in the image. This approach used to detect the real edge points and non edge points. It should maximize the real edge points and minimize the non edge points. These similarities to maximize the signal to noise ratio. The detected edges as close as to the real edges. The real edge should not result as the detected edge. Using a canny edge detection algorithm the visual perception of the image can be improved.","PeriodicalId":176197,"journal":{"name":"2014 International Conference on Computation of Power, Energy, Information and Communication (ICCPEIC)","volume":"32 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-04-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125394623","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 proposed system raises the overall efficiency by incorporating soft-switching technique in addition to MPPT. The algorithm used to track maximum possible power from the PV panel was variable step size algorithm, being superior over other methods due to its ability to change the step size according to the MPP. The above mentioned converter with MPPT is found to be highly efficient (around 96%) compared to other converters with MPPT because of reduced ripple and reduced switching losses. So it can be applied for high voltage as well as high power applications such as in space crafts, hybrid electric vehicles, dc back up energy systems, power factor correctors etc. It can also be used for grid connected and micro-grid applications because of low output voltage ripple. In this work, design and simulation has been done in MATLAB software to verify the performance of the converter with MPPT.","PeriodicalId":176197,"journal":{"name":"2014 International Conference on Computation of Power, Energy, Information and Communication (ICCPEIC)","volume":"23 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-04-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115780540","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}

And it cannot be fulfilled by using finite sources only. So the renewable energy sources are going to play a key role in the future. Now-a-days DGs are also used for supplying power to the consumers. DGs are connected normally to the primary distribution network. It works along with the supply from main grid, but when supply is cut off from the main grid due to some fault, these DGs operates in islanding mode. Combination of a number of DGs to form a low scale power system is called a microgrid (μ-grid). This paper involves modeling and study of grid connected distributed generation based hybrid system under different fault conditions. The modeling and simulation of hybrid PV generation system and wind generation based hybrid system has been done in this paper. And outputs of these models under different fault conditions are compared. These studies are done for two situations. First when the DGs are operating in normal condition along with the main grid. And the second situation is when the DGs are operating in islanding mode.

PECEP is based on Complex Event Processing (CEP) and Probabilistic Fuzzy Logic (PFL). CEP is event processing that combines data from multiple sources to infer events or patterns that suggest more complicated circumstances. The main aim of CEP is to identify meaningful events such as opportunities or threats and respond to them as quickly as possible. A PFL is a type of logic that recognizes more than simple truth values. Fuzzy logic can be represented with degrees of truthfulness and falsehood. The event data are downloaded and updated dynamically from the online data source. PECEP consists of three steps namely Collection of Data Set, Feature Processing and Machine Learning. PECEP is validated using Esper in the stock market domain. A stock market or equity market is a public entity for the trading of company stock and derivatives at an agreed price. The output of the PECEP provides a guideline about the future price of stock. The performance of PECEP is compared with the existing system in terms of the four parameters- Accuracy, Error Rate Analysis, Processing Time and Throughput.","PeriodicalId":176197,"journal":{"name":"2014 International Conference on Computation of Power, Energy, Information and Communication (ICCPEIC)","volume":"14 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-04-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124614677","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}
