With the help of Internet, Massive Open Online Courses (MOOC) are recognized as a new path to learn courses via the web instead of in the traditional classrooms. MOOC can break many limits such as distance, time, participants, on the traditional courses. At the same time, it brings some new issues, such as high drop out ratio. Nowadays increasing MOOC courses are available and even more common people...
As cloud computing grows rapidly and virtualization techniques become more widely-used, it is critical and important to allocate limited resources to various applications on demand for the cloud service environments. In this article, we propose an adaptive resource management approach considering multi-resource transformation to fully utilize extra resource capacity. The definition of the optimization...
Simulation plays an important role in both academic research and industrial development and manufactory. The users' requirements for simulation are often complex and diverse. It is time consuming and error-prone for users to build different simulation environments manually to conduct their simulation tasks. An Automatic Simulation Environment Customizing Service for Cloud Simulation Center is presented...
Service-oriented architecture and cloud computing are becoming a dominant computing paradigm, as all major computing companies are supporting this paradigm and more and more organizations are adopting this paradigm. Robotics and service-oriented robotics computing start to joint this new paradigm in the past five years and are now ready to participate in large scale. This paper reports our research...
Virtualization technologies are becoming more and more widely used in the distributed computing area. In order to organize and manage various virtual machines in the SOA (Service Oriented Architecture) environment more effectively, a virtualization management system called SOAVM is proposed and demonstrated in this paper. SOAVM addresses the limitation of virtual appliances in software quantities...
This paper presents a mechanism that automatically build evaluation metadata for grid services by using the information from the execution of different applications. A new MetaService AMDBS, automatic metadata building service, is designed to support this mechanism. The typical feature of this mechanism is that it can get not only the absolute evaluation information, but also the relative global ranking...
This paper focuses on architecture suitable for large-scale simulation system. Based on the scenario of large-scale Internet simulation, the grid technology is introduced and a new architecture, GDSA is proposed. GDSA, a full grid-based architecture mainly focuses on four pending problems in distributed system: scalability, communications, management mechanism and QoS insurance computing environment...
