In recent years, E-learning has been in a continuous development, due to the fact that it eases the process of teaching, evaluation and selfevaluation, offering schedulling flexibility and a tool support. E-learning makes learning content available even in remote locations, eliminating the need to travel to the place where the content is delivered. Nevertheless, the current E-learning platforms have...
Firstly, the significance of EMR sharing and interchanging in the Internet environment is introduced. Then, the method to realize multi-source heterogeneous EMR systems' integration and data sharing is proposed with grid middleware technology. To establish the mapping mechanism from ontology to data source, the ontology modeling technology which generates ontology database of medical information is...
The Internet of Things (IoT) refers to extending the Internet to devices such as home appliances, consumer electronics, and sensor networks. As multiple heterogeneous devices attempt to create area networks, one of the major challenges is the interoperability and composability of their services. The traditional way to address interoperability is to define standards; however, there are many standards...
The following topics are dealt with: software evolution; Word Wide Web; security of data; user interface; computer graphics; service-oriented system; software testing; data visualization; computer science education; and middleware.
The telecommunications converged networks, specially inside of new Internet environment, makes possible supply a plenty of services to users, as voice and multimedia services with assured perceived quality of services (QoS) through different access technologies, however this brings a complex scenario in terms of technology in order to fit the user perceived QoS needs to appropriate technical QoS requirements,...
Distributed simulations are mainly used to interoperate heterogeneous simulators or geographically distributed models. We present here RESTful-CD++, the first distributed simulation middleware based on REST (Representational State Transfer) Web-services. RESTful-CD++ middleware enables heterogeneous independent-developed simulation components to interoperate with much flexibility and simplicity. REST...
The complexity of modern data centers has evolved significantly in recent years. One typically is comprised of a large number and types of middleware and applications that are hosted in a heterogeneous pool of both physical and virtual servers, connected by a complex web of virtual and physical networks. Therefore, to manage everything in a data center, system administrators usually need a plethora...
The technologies for the digital broadcasting over a network are an emerging technology that provides a more function-rich, user interaction form of TV to the customer. This represents a change from low interactivity to moderate interactivity and high interactivity. The important thing is a IPTV set-top box (STB) which is a embedded system providing two-way communications using Internet Protocol over...
Grid computing is becoming more and more attractive for coordinating large-scale heterogeneous resource sharing and problem solving. Although Globus toolkit version 4 which is developed based on WSRF can successfully deal with the heterogeneity of resources and the diversity of applications, the current grid environments based on Globus toolkit version 4 have several limitations regarding dynamic...
In this paper, the Deep Web technologies are analyzed and discussed, and a middleware of finding and integrating Deep Web query interface automatically is proposed. This middleware extracts the attributes of query interfaces and judges them whether interfaces of Web databases by computing the similarity between them; it can also cluster query interfaces and construct an integrated query interface...
The MIT iLab project has developed a distributed service infrastructure and software toolkit to support a scalable community of online laboratory experiments. The iLab shared architecture provides a framework for the development and deployment of remote laboratories using a three-tiered model based on Web services consisting of lab clients, service broker middleware, and lab servers. This simplifies...
The advent of affordable high performance computing (HPC) resources, such as computing clusters and grids, has transformed the computational capabilities of many organizations. However, the lack of convenient interfaces to such valuable resources limits their effectiveness, restricting their user base to a small set of highly skilled programmers and computer scientists. Without such an interface,...
A context-aware service is a user-centric and flexible network service based on a user context. To realize such a context-aware service, we must coordinate various resources such as Web applications, sensor networks, information appliances, context information and actuators. However, it is difficult to coordinate resources described in different protocols. Toward constructing a framework for any resource,...
Common design patterns in application development mix implementation of business logic with application logic, user interface logic, or with data access logic. This leads to results that business logic is not well maintainable and reusable, the application code should be reimplemented each time the business logic has changed or the same business logic should be reimplemented for each application....
The following topics are dealt with: enterprise resource planning; business process reengineering; distance education; Internet; management information system; electronic commerce; knowledge management; data mining; data warehousing; optimisation; middleware; user interface; information retrieval
