The technique is widely used in process industries and also in strategic sector like nuclear. In the case of ISI in nuclear industry, the main difficulties likely to arise during such inspection are the high temperature (during shut down) and the background radiation. With the advent of high temperature probes, this limitation can be overcome. However, a fundamental factor which still is a cause for concern is the degradation of the signal to noise ratio due to thermal noise. Experiments conducted by the authors reveal that the contrast of acquired TOFD Images reduces progressively with increasing temperatures. As the temperature increases beyond 373K, the noise makes interpretation of images difficult and thus possibility of linear defects getting missed out arise. It is well known that the wavelets can be effectively employed for denoising. Wavelets have also been applied in general for denoising UT signals. However, its application for UT signals from stainless steel and which is at high temperature has not been attempted so far. In this paper, we explore the innovative application of wavelet thresholding for denoising applications due to its greater flexibility. Analysis of the restored image indicate that the Symlets family with the suitable thresholding has Higher Peak Signal to Noise Ratio(PSNR) value than the Coiflets wavelet family.","PeriodicalId":113531,"journal":{"name":"2013 International Conference on Recent Trends in Information Technology (ICRTIT)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-07-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129972242","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 may result in tasks getting completed in other clouds that have more computational power or currently have free resources to service the request. In this paper a new task scheduling approach has been considered that not only considers the effective finish time of clouds as parameters similar to list scheduling, but also takes into account the latency of networks involved in the federation. This consideration is due to the fact that the estimated finish time may differ from actual finish time of tasks when there is a communication delay between clouds in the federation. When dependency among tasks are considered it becomes necessary that a dependent task can start execution only if its predecessors have completed. So if the predecessor task has been scheduled in a different cloud the calculation of estimated finish time with communication delay will help in finding the proper cloud to schedule the task. This would not be possible if the communication delay is not considered as a parameter in estimating the finish time of task. By this approach make-span time of an application which is a set of tasks can be considerably reduced. The experimental results show that the proposed method outperforms the existing list scheduling algorithm.","PeriodicalId":113531,"journal":{"name":"2013 International Conference on Recent Trends in Information Technology (ICRTIT)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-07-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"120962691","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 provides many benefits for the users to create and store health care data on the cloud thereby utilizing fewer resources in the client system. The proposed system mainly focuses on health care data security. To reduce the increase in cost of hospitalization, researchers are building Smart Health care environment where medical data are continuously monitored by health experts. Some of the major imports that still need to be discussed before these devices get a wide acceptance include the security and privacy of medical data collected by these devices. Enhanced RSA is a technique which uses random integer as an additional technique in traditional RSA. Enhanced RSA based storage security method uses encryption and decryption technique of the remote data by improving existing RSA based encryption and decryption. The encrypted data will be stored in the cloud using provable data possession scheme. To improve the privacy and security, the primal based privacy technique is used in securing the health care data. The proposed technique provides better security. Using this proposed method, the correctness of health care data is assured and identification of file block existence in the cloud is performed. This method also supports insertion, modification and deletion of the data and tries to reduce the calculation time of the server. The attacks are made with encrypted data and the results shows that the proposed scheme outperforms with improved security in data storage when compared to the existing methods.","PeriodicalId":113531,"journal":{"name":"2013 International Conference on Recent Trends in Information Technology (ICRTIT)","volume":"111 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-07-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129439461","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}

Not all communications are credible and malpractice can arise anywhere, anytime. If the normal traffic is slightly modified to delude the intrusion detection system, then the traditional systems might not be able to discern the same effectively. Thus, a system that could detect and ferret out the novel attacks has been proposed. Since any number of users can use a web page, maintaining the availability of the resources and allocating them to the active users as per their need is very essential. The multi-thread concept is used to share the resources that each client can use. Attribute Selection Algorithm is used as the feature extraction algorithm in weka, to yield those relevant features pertaining to the user's request and helps in achieving a more accurate result. Memory efficiency is brought in with the cascading binary search tree. The patterns are efficiently stored and hence the search for the presence of an attack is accomplished effectively. An Intrusion Detection System which is memory efficient and effective enough in detecting attacks and reducing the false positives is thus proposed.","PeriodicalId":113531,"journal":{"name":"2013 International Conference on Recent Trends in Information Technology (ICRTIT)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-07-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122474729","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}
