The images are sparse representation. The images are divided into blocks via the sliding window. The dictionary is compiled the column vectors. The redundant dictionary is learned by the K-singular value decomposition (K-SVD) algorithm. Then we solve the sparse coefficient matrix for each original image. And combining sparse coefficient of nonzero elements realizes the image feature fusion. Finally, the reconstructed fusion image is obtained from the combined sparse coefficients and the overcomplete dictionary. The method in this paper is capable of extracting image features and the strong anti noise interference. Experiments show that this method better preserves the useful information in the original image and the fusion image details are clear. Compared with other fusion algorithms, the results show that the proposed method has better fusion performance in both noiseless and noisy situations and is superior.","PeriodicalId":395610,"journal":{"name":"2014 Ninth International Conference on P2P, Parallel, Grid, Cloud and Internet Computing","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-11-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126206758","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}

Further, we analyze the performance of this time protocol due to relative motion with two spacecraft through using STK and Mat lab software jointly simulation. Regard the influencing factors such as relative distance between the two spacecraft, the relative distance changes rate and time synchronization error curve relative motion of spacecraft that impact on the time synchronization accuracy. Finally, under conditions known to spacecraft orbit, this paper utilizes a error curve fitting compensating method to reduce space network time synchronization protocol synchronization in the application of the relative movement state. It is significant improvement in time synchronization errors.","PeriodicalId":395610,"journal":{"name":"2014 Ninth International Conference on P2P, Parallel, Grid, Cloud and Internet Computing","volume":"105 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-11-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124064711","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}

To address such a requirements a series of solutions for distributed knowledge management have been proposed over the last decade, among which the most promising is the so-called knowledge grid. Such infrastructures have been traditionally designed for science and educational applications, but they are starting to be progressively used in more critical scenarios, such as disaster management and recovery, or financial services. This imposes the need of providing reliability and security within the context of knowledge grids. The goal of this paper is to define such needs and to describe the correspondence of the available solutions to these needs.

However, some common problems, such as long startup delay and unsmooth playback, seriously restrict user's experience on live streaming. In this paper, we propose a novel but simple scheme, namely guarantee mechanism of contingency resource (GMCR), which can improve the quality of service (QoS) of live streaming by deploying a contingency server to provide contingency service for those chunks whose playback deadlines are urgent. Then we establish a queuing model to analyze the quantitative relation between the amount of contingency server resources and the level of user's QoS. Finally, we simulate our scheme in a P2P live streaming simulation platform, and obtain the optimal value of some critical parameters. The results of theoretical analysis and simulation experiment present the feasibility and validity of GMCR scheme.","PeriodicalId":395610,"journal":{"name":"2014 Ninth International Conference on P2P, Parallel, Grid, Cloud and Internet Computing","volume":"9 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-11-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130186344","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}
