By facilitating these applications with the cloud services, it helps to overcome the inherent limitations of mobile/portable devices that are faced by their mobile applications. However, the cloud services in existing architecture become tightly coupled with the mobile applications while delivering the service, which is highly undesirable in the dynamic and unreliable mobile cloud computing paradigm. In this paper, a new mobile cloud computing architecture is proposed, where the mobile applications remain uncoupled from the leased cloud services during the service delivery. In this architecture, the tuple space model is used for uncoupling these interactions. The proposed approach of uncoupling improves the flexibility and efficiency of mobile cloud computing. This paper also suggests an approach for formalizing and reasoning of the proposed architecture, in order to properly validate its flexibility and efficiency while uncoupling the service access and delivery to the mobile applications. The formalization is carried out using Mobile UNITY.","PeriodicalId":435920,"journal":{"name":"Compute","volume":"84 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-08-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114723493","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}

Our objective is to analyze, design and implement the above mentioned system to enhance the machine's understanding of humans based upon affective behavior of humans. This work follows vision based techniques for recognition and identification of a vast range of non-overlapping body poses. The problem in body-posture identification is the inherent complexity of poses, like same pose can be present in a number of different scenarios or situations. Therefore it is inappropriate to guess the exact pose without identifying facial gestures, hand gestures and speech. Hence our approach is to identify the exact position of arms, head, shoulders and torso, so that, we can estimate the intensity of any pose and also identify possible emotion(s) under which this pose is expressed. The accuracy of this system is as good as 92%.","PeriodicalId":435920,"journal":{"name":"Compute","volume":"104 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-01-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133139541","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 this paper, we define a framework to improve the performance of a base classifier, by clustering the unlabeled data with labeled data using clustering algorithm (training of samples) labeling of clusters (majority voting for each Hyperspheres) and final generated classified data. We have used construction of BNN based semi-supervised classifier while training and testing of the classifier is performed. We have studied and customized a supervised classification algorithm to form out semi-supervised classification that leads to design a multiclass semi-supervised classifier using geometrical expansion. The experimental result shows provision for the classifier designer followed by training and testing medical disease dataset using pre-decided samples. Our classification model consists of training phase that covers two process clustering and labeling to perform classification task of medical data and the binary neural network is trained. In this we used two techniques normalization and quantization for pre-processing the datasets. Pre-processing impart various outcomes after applying the classification model like number of hypersphere, confusing samples that cannot be learned, training time and label of hypersphere. Comparison has been done for implementation and design of Binary Neural Network Classifier Algorithm with the other existing traditional algorithms. Our classifier evaluates performance in terms of generalization, number of hidden neuron and accuracy etc. The BNN-CA construct three-layered binary neural network (BNN) and can solve any semi-labeled multi-class problem.","PeriodicalId":435920,"journal":{"name":"Compute","volume":"48 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-01-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133756863","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 this paper, we introduce a new approach for deriving edge based features for retrieval of medical images. Texture edges are known to represent the tissue boundaries better than intensity edges in medical images. Therefore, we use texture edges for describing image structure instead of traditional approach of using intensity edges. We demonstrate that retrieval performance at organ level in medical images using texture edges is superior to intensity edges.","PeriodicalId":435920,"journal":{"name":"Compute","volume":"7 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-01-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116988338","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}
