These networks are also referred to as delay/disruption tolerant networks as the applications in this networks, must tolerate delays beyond conventional IP forwarding delays. Routing in ICMANs is a challenging task, as there does not exist a complete path from source to destination. For this network, researchers proposed many routing approaches. These approaches use the information like contact history, contact patterns, encounter time rates, utility functions, location information etc. to forward the message to the successive nodes so as to make it reach the destination. The recent routing protocols and algorithms are discussed in this article.","PeriodicalId":197580,"journal":{"name":"International Conference & Workshop on Emerging Trends in Technology","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2011-02-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122028888","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}

Image classification can be done using conventional methods. But conventional methods lead to misclassification due to strictly convex boundaries. Textural features are included for better classification but are inconvenient for conventional methods. The proposed system uses textural feature based image classification using neural network. Textural features are extracted using Gray level co-occurrence matrix and artificial neural network is developed for the classification of images into different classes. Neural network is trained by supervised learning using standard back propagation algorithm for the classification of images.","PeriodicalId":197580,"journal":{"name":"International Conference & Workshop on Emerging Trends in Technology","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2011-02-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122155467","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 companies can study visitor's activities through web analysis, but before performing analysis we need to discover pattern and find the patterns in the visitor's behavior.

Spectral Subtraction Technique is one earliest and longer standing, popular approaches to noise compensation and speech enhancement. It reduces stationary noise but the non stationary noise still passes through it. Further, it also introduces a musical noise which is very annoying to human ears. Beamforming is another possible method of speech enhancement that can be used. Beamforming by itself, however, does not appear to provide enough improvement. Further, the performance of Beamforming becomes worse if the noise source comes from many directions or the speech has strong reverberation. A combined technique using the Spectral Subtraction Technique followed by Beamforming Technique reduces stationary as well as residual, musical noise. It can be observed that the Spectral Subtraction followed by Beamforming gives better SNR value as compared to that of individual techniques, thereby improving the quality of speech. Numerous simulation results are used to illustrate the reasoning.","PeriodicalId":197580,"journal":{"name":"International Conference & Workshop on Emerging Trends in Technology","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2011-02-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128799088","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 even though the delivery chain for these \"borderless applications\" now crosses organizational and geographic boundaries, users will still expect the applications to perform well, and they will hold IT accountable if they don't. For its part, IT is faced with managing an increasingly complex and diverse delivery chain, consisting of perhaps dozens of service and content providers spread around the world. Cloud computing is the set of technologies and infrastructure capabilities being offered in a utility based consumption model. Windows Azure is Microsoft's Cloud Computing offering to help its customers realize the benefits of cloud computing. This paper is an introduction on Windows Azure and provides insights into different aspects of Azure based development, especially for those who are interested in adopting Windows Azure within their Enterprise IT landscape. The key aspects we shall be discussing in this paper include overview of cloud computing, Windows Azure platform components, features, implementation, creating a cloud project in Windows Azure and developer's perspective about Azure.","PeriodicalId":197580,"journal":{"name":"International Conference & Workshop on Emerging Trends in Technology","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2011-02-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126987828","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}

An important objective of Grid scheduling is improving overall system performance by increasing system throughput, efficiency, and decreasing job completion time. Existing approaches of Grid scheduling doesn't give much emphasis on the performance of a Grid scheduler. We have specifically focused on improving Computational grid performance in terms of time. In this paper a non preemptive and dynamic scheduling strategy is proposed. This strategy toggle between Space based strategy and Time based strategy. The result of proposed scheduling strategy has been compared with existing scheduling strategies i. e. FCFS and Round Robin. Comparison takes place in terms of Execution time as a performance metrics. The proposed algorithm has been verified through the GridSim simulation toolkit and the simulation results confirm that the proposed algorithm gives better performance compare to other two strategies.","PeriodicalId":197580,"journal":{"name":"International Conference & Workshop on Emerging Trends in Technology","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2011-02-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"120954457","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}
