There is an increasing interest in providing Computer Science (CS) instruction to a wider sector of the population. On the one hand, it would be convenient to include CS instruction in higher education beyond engineering disciplines, since CS has become a powerful catalyzer for development of society, and therefore the need for a workforce with solid CS background is growing. On the other hand, it...
The core issue of digital city construction is spatial information sharing. This paper presents a new viewpoint that spatial information sharing has three factors which are subject, object and medium, and their forms and function transform when sharing model changed. It is showed that service-oriented spatial information sharing is the main pattern of digital city constructions today due to its many...
Current theories and systems do not satisfy the requirements of P2P streaming on Internet in aspects of large scale, high quality and low cost. The transmission model of overlay network is the key factor. This paper proposes Regular Structured Model for P2P streaming including overlay network theory and management mechanisms. We developed ClusterStream a high service quality streaming system based...
Service-Oriented Architecture (SOA) is a new software architecture. This paper introduces relevant theory of SOA and Web Service as one of the measures to achieve SOA, and presents an integrated framework based on web services. Furthermore, aims at the problems aroused in daily computer facilities maintenance that the University Modern Education Technology Center faces, the paper carries out analysis...
How to realize the exchange, integration and sharing of information resources is one of the key problems during the informatization of spaceflight launch site. The technology of SOA, Web Services and XML were described based on the analysis of integration and sharing problems about information resources in spaceflight launch site. According to the loose coupling idea of service-oriented, one integration...
Service oriented architecture (SOA) is a newly emerged and future method based on the Web services and SOAP for IT development in a distributed environment. As a state-of-art architecture, its concrete details are absent by its nature. This paper is intended to provide a mechanism for an IT system to dynamically adapt itself to business application logic at the system runtime, that is, a mechanism...
The goal of this work is develop and test of a new software archetype, to aid the competence management process in Post-Graduate of Production Engineering Courses. This system will be designed using JADE Agent Framework, to read and analyze XML data. Those technologies have been used to build an innovative environment for software building. The research methodology used in this scientific work is...
Among many service choreography description languages, WS-CDL which has been developed by W3C is the most popular one. This language is an intermediate language mostly considered as a design language to describe the choreography, and is unable to model the choreography in high level. Regard to this issue, this paper proposes a set of notations, used at the analysis phase, help user to express the...
QoS-aware service management and composition has become an interesting research topic with the rapid development of service oriented architecture (SOA). Differently with Web-services based systems, the emergence of peer-to-peer (P2P) based distributed network technology brings more challenge to the QoS-aware service management and composition. In this paper, we propose our design of a QoS-aware hierarchical...
ST-Guide is a computer-interpretable clinical guidelines development, verification, and implementation project focused on primary care to chronic disease patients. It can be used to implement guides in different modes: authoritarian, apprentice, specialist, and auditor. Only specialist and authoritarian modes are functional in this release. This paper presents the projectpsilas web services module,...
Current fashion systems to interconnect large software architectures are moving toward SOA based solutions. This new paradigm for designing system can be improved, in our opinion, by using semantics. Semantics can a play a main role in boosting interoperability thanks to current technologies to express knowledge and to describe semantic Web services (SWS). This paper tackles the provision of a Software...
