Proposal of Cloud Computing is tightly coupled withlow cost. Reduction of cost is considered as an importantadvantage of Cloud. However, there are no availabletools proper for cost calculation and analysis in Cloudenvironment. This paper presents our efforts towardsfilling in the gap. We format suits of metrics and formulasfor the calculation of Cloud Total(More)
Recently, there is appearing a multi Infrastructure as a Service (IaaS) cloud site environment. It makes server users/administrators annoying because each cloud site is managed separately by each cloud owner and they have to make use of cloud sites individually. In this paper, we propose the Multi Cloud Management Platform that locates between cloud users(More)
The Lattice Boltzmann method, a molecule kinetic-based approach, is presented to solve fluid dynamics. Based on the theory of turbulence and molecule kinetics, an extended Lattice Boltzmann equation is put forward to solve turbulent flow with high Reynolds number, in which sub-grid turbulence model is used to simulate vortex viscosity as well as turbulence(More)
High throughput technology has prompted the progressive omics studies, including genomics and transcriptomics. We have reviewed the improvement of comparative omic studies, which are attributed to the high throughput measurement of next generation sequencing technology. Comparative genomics have been successfully applied to evolution analysis while(More)
Autonomic computing middleware is a promising way to enable middleware based systems to cope with the rapid and continuous changes in the era of Internet. Technically, there have been three fundamental and challenging capabilities to an autonomic computing middleware, including how to monitor, reason and control middleware platform and applications. This(More)
Services computing paradigm together with Web services have significantly promoted the automation of business process in enterprise. Prevalent service composition technologies, such as WS-BPEL and WSCI, provide promising means to deal with machine-to-machine communication. Traditionally, in the phase of business process modeling, there usually require some(More)
Being a popular runtime infrastructure in the era of Internet, middleware provides more and more services to support the development, deployment and management of distributed systems. At the same time, the reliability of middleware services has a significant impact on the overall reliability of the system. Different services have different impacts and(More)
