Cloud storage service has been increasing in popularity as cloud computing plays an important role in the IT domain. Users can be relieved of the burden of storage and computation, by outsourcing the large data files to the cloud servers. However, from the cloud service providers' point of view, it is wise to utilize the data deduplication techniques to reduce the costs of running large storage system...
Many companies want to share data for datamining tasks. However, the privacy and security concerns become a bottleneck in the data sharing filed. The secure multiparty computation (SMC)-based privacy-preserving data mining has emerged as a solution to this problem. However, traditional SMC solutions are inefficient. We introduce the method of outsourcing to reduce the computation cost of user’s side...
Cloud Map-Reduce (CMR) is an advantage Map-Reduce platform and has been aroused more and more attention. To further balance the performance of job secluding among job cost, execution time and energy consumption, a locality-aware and energy-aware job pre-assignment algorithm is proposed for Map-Reduce of CMR in this paper. Firstly, the importance of rack in data locality and energy saving is analyzed...
Cloud storage service allows data owner to store their big data in the cloud and provides data access to the users. As the cloud server is not trustworthy, we cannot rely on the server to conduct data access control. To protect data security and privacy, Attribute-Based Encryption (ABE) is a promising technique for data access control in cloud storage, because it provides data owner more direct control...
Servers and network contribute about 60% to the total cost of data center in cloud computing. How to efficiently place virtual machines so that the cost can be saved as much as possible, while guaranteeing the quality of service plays a critical role in enhancing the competitiveness of service cloud provider. Considering the heterogeneous servers and the random property of multiple resources requirements...
To solve the parallelism algorithm of Petri network system with parallel feature and implementing paralleling control and execution of Petri network, we propose the analysis and algorithm design of Petri network process. Based on employing P-invariants to partition the function of Petri network system, we firstly analyzed the situations of parallelism between processes, checked the effects of the...
This paper is focused on modeling Web request and session level arrival processes. We propose a statistically rigorous approach which includes testing for non-stationarity and Gaussianity, and uses model selection criterion. Furthermore, a goodness of fit test is applied to each candidate model - ARMA, ARIMA, FARIMA, and FGN - and for validation purpose real data is compared with data simulated from...
The China-Austria OnLine-Diagnosis Medical-Measurement Grid computing system (CAODMMG) consist of a special novel non-invasive medical measurement (NIMM) based on the combination of modern medical measurement, modern information theory and traditional Chinese medical theory, the Grid computing system equipped by the newly practically developed workflow engine (WEEP) and in-computer-embedded complete...
A newly developed hard/soft-ware technology of designing a computational server of industrial control grid, called FPGA-CS, replacing the traditional grid-computational server which is located on hart-disk of industrial control computer (ICC) by using a FPGA-based grid-computational server which is embedded into the ICC through PCI-bus slot, is suggested. Also the test experiment and application are...
