The rapid development of web service technology brings up a number of crucial requirements for designing service computing runtime, such as supporting multiple message exchange patterns, switching among different transports, integrating various extended web service protocols and achieving robust performance under high concurrency. Based on staged event-driven architecture, we propose a novel architecture...
The geospatial data such as ocean in situ observing data, remotely sensed data, and model output are produced in a distributed geographical environment. These data have significant scientific value to construct Digital Ocean. However, given the relatively high temporal frequency and the intrinsic spatial nature of the data, the data set is relatively difficult to use directly by Digital Ocean system...
Instead of the original wired IP networks, the mobile networks are used as the return channel in IP-QAM VOD system to take the advantage of their wireless data communication function and full coverage in cities. The mobiles are used as a virtual remoter of STB for demanding video programs and controlling their playing. The function of complex query for programs can be realized based on the mobile's...
Nowadays, there are increasing amount of data fields of tide and tidal current gained from ocean dynamical environment real-time stereo monitoring platform, model calculation and numerical simulation. Collaborative visualization of these data fields on the internet is becoming increasingly important for the utility of data. In this paper, we summarize the characters of tide and tidal current data...
In this paper, we present a formal description of Web services container architecture based on Z notation. This description major focuses on internal behavior of a Web services container on processing a Web services request. First, we present a formal model of tailored XML which provides a unified data structure for executing Web services specifications and data transformation. Then, we present a...
In this paper, we present a formal model of Web services transport layer based on CSP which addresses multiple transport, multiple Message Exchange Patterns (MEPs) and dynamic switching among multiple transport protocols. This approach abstracts message transferred over networks as transport object and splits message transportation process of a transport protocol into two CSP processes: a transport...
What we are proposing in this paper is the concept, architecture and application of a Web-based simulation meta-synthesis (WebSMS). The motivation of the WebSMS system is to provide services for distributed and secure sharing and reuse of resource, distributed collaboration, and distributed execution and observation of simulation. In this paper, our initial work designing and developing a web-based...
In this paper, we present an adaptive transport framework which addresses multiple message exchange patterns (MEPs) and transparent switching between multiple transports for Web services. In the framework, we separate the transportation process into transport input stage and transport output stage by using pipelined pattern. Moreover, we introduce a set of abstractions, such as transport protocol,...
The Web services technology has been initiated by industry, and lots of large companies are working on Web services technology and apply it in real world applications. However, the existing Web service registration and discovery are processed in a centralized approach, which cannot easily scale to a growing number of users. With the advantages of scalability and fault-tolerance, P2P technology is...
Integrated examination management system (IEMS) has become trend and future direction for future examination management in China. As there are many and versatile kinds of examinations, to develop a ubiquitous IEMS is a great technical challenge. The numerous legacy systems and evolving requirements of examinations make such a system more complex. Existing systems focus on one phase of IEMS and they...
