Cloud computing will be a major technology in the development of the future Internet of Services. Service providers want to remove the bottle neck of the cloud computing system in order to satisfy user requirement. And in order to save energy consumption they also need to apply new energy-efficiency mechanism and observe its effects on a data center. As it(More)
The role of thymidylate synthase (TS) is essential as a key rate-limiting enzyme in DNA synthesis. It is the primary target of fluorouracil and its derivates in colorectal cancer. In this study, TS mRNA expression was examined in primary tumor and normal tissues from 76 patients with high- risk stage II/III colorectal cancer by laser capture microdissection(More)
An automated method of penetration testing was proposed, which is deigned to solve the problems such as high cost and low efficiency in the traditional penetration testing. This method consists of two parts: the automatic generating method of the penetration testing scheme and the automatic executing method of penetration testing scheme. We design and(More)
At present, in researches of Iaas cloud resource scheduling strategies, it is focused that SLA violation or overloaded physical machine can trigger the migration of virtual machines, which will reduce the performance of the system and cause extra energy cost. In this paper, we model the resource of IaaS cloud based on Hidden Markov process to predict the(More)
Due to the wide applications of IaaS (Infrastructure as a Service), energy-saving technologies of IaaS clouds has attracted much attention. However, it is very difficult for IaaS cloud providers to guarantee both of energy saving and performance under the condition of satisfying SLA (Service Level Agreement). Recently, adaptive-threshold-based methods are(More)
With the development of cloud infrastructure services, IaaS(Infrastructure as a Service) study on energy-saving technology has been attracted more and more attention. IaaS platform providers can provide high performance service for the users. Meanwhile, how to save the energy cost of the cloud platform must be considered without violating the Service Level(More)
Safety requirements have commanded increasing attention as software is playing a more and more important role in today's safety critical systems. As many experts, scholars have found that the main reason for safety critical systems' accident is bad requirements which means inaccurate, incomplete or inconsistent requirements may lead to misunderstanding of(More)
