Automated syntactic mediation for Web service integration

As the Web Services and Grid community adopt Semantic Web technology, we observe a shift towards higher-level workflow composition and service discovery practices. While this provides excellent functionality to non-expert users, more sophisticated middleware is required to hide the details of service invocation and service integration. An investigation of a common Bioinformatics use case reveals that the execution of high-level workflow designs requires additional processing to harmonise syntactically incompatible service interfaces. In this paper, we present an architecture to support the automatic reconciliation of data formats in such Web Service worklflows. The mediation of data is driven by ontologies that encapsulate the information contained in heterogeneous data structures supplying a common, conceptual data representation. Data conversion is carried out by a Configurable Mediator component, consuming mappings between \xml schemas and \owl ontologies. We describe our system and give examples of our mapping language against the background of a Bioinformatics use case

Physical Layer Service Integration in 5G: Potentials and Challenges

High transmission rate and secure communication have been identified as the key targets that need to be effectively addressed by fifth generation (5G) wireless systems. In this context, the concept of physical-layer security becomes attractive, as it can establish perfect security using only the characteristics of wireless medium. Nonetheless, to further increase the spectral efficiency, an emerging concept, termed physical-layer service integration (PHY-SI), has been recognized as an effective means. Its basic idea is to combine multiple coexisting services, i.e., multicast/broadcast service and confidential service, into one integral service for one-time transmission at the transmitter side. This article first provides a tutorial on typical PHY-SI models. Furthermore, we propose some state-of-the-art solutions to improve the overall performance of PHY-SI in certain important communication scenarios. In particular, we highlight the extension of several concepts borrowed from conventional single-service communications, such as artificial noise (AN), eigenmode transmission etc., to the scenario of PHY-SI. These techniques are shown to be effective in the design of reliable and robust PHY-SI schemes. Finally, several potential research directions are identified for future work.Comment: 12 pages, 7 figure

The evaluation of educational service integration in integrated virtual courses

The effectiveness of an integrated virtual course is determined by factors such as the navigability of the system. We argue that in a virtual course, which offers different educational services for different learning activities, the integration of services is a good indicator for the effectiveness of a virtual course infrastructure. We develop a set of metrics to measure the degree of integration of a virtual course. We combine structural metrics and an analysis of the student usage of the system in order to measure integration

Food service in museums and galleries: Dreamscape spaces for extended contemplation of the beautiful and the sublime

Concerning tourist consumption, food purchasing is commonly regarded as a key purchase for those seeking a distinct, sensory experience. Suitably focused food service design promotes reflection upon the holiday environment's cultural differences, compared to that of the everyday, and many tourist domain food offerings can be seen to have been designed to amplify this effect. This culture-food service integration, however, has not been much studied relative to museum cafés, although museum and gallery visits also form a type of leisure ‘break’ from everyday surroundings within a culture-laden environment. This paper explores the ideal spatial design dimensions of various museums, art galleries and historic house relative to food service integration. It proposes theoretical design dimensions, characteristics and considerations for the spatial design of the foodservice offer, as divined from consumer narratives concerning the ideal holistic visit experience

QuizPower: a mobile app with app inventor and XAMPP service integration

This paper details the development of a mobile app for the Android operating system using MIT App Inventor language and development platform. The app, Quiz Power, provides students a way to study course material in an engaging and effective manner. At its current stage the app is intended strictly for use in a mobile app with App Inventor course, although it provides the facility to be adapted for other courses by simply changing the web data store. Development occurred during the spring semester of 2013. Students in the course played a vital role in providing feedback on course material, which would be the basis for the structure of the quiz as well as the questions. The significance of the project is the integration of the MIT App Inventor service with a web service implemented and managed by the department

The Design of an XMPP-based Service Integration Scheme

[[abstract]]The advances in network-enabled software development raises the demands on the service oriented architecture (SOA). Popular implementations of SOA uses XML-based representations, such as SOAP and WSDL, to enable remote function invocation and service discovery. Our previous experiences show that a sophisticated XML representation is often over-complex for a controlled environment. We also found that the application composition is a high-level operation. Therefore, a proper infrastructure for hosting and delivering various kinds of services is required. We then proposed an XMPP-based solution to overcome these issues. A service is an XMPP client, and focus on how to interact with the other clients, the management of the service can be flexibly arranged through the proposed format of its full JID, and the fundamental security are handled by the XMPP server and the publisher-subscriber pattern.[[incitationindex]]EI[[conferencetype]]國際[[conferencedate]]20111014~20111016[[conferencelocation]]Dalian, Chin

Towards digital library service integration

Digital Library Service Integration (DLSI) aims to provide a systematic approach in integrating the services and collections of National Science and Digital Library. The National Science and Digital Library collections can share the services among themselves in a totally integrated environinent. Collections as such will require no change to plug into the DLSI architecture. Collections will keep using the services of NSDL in the similar manner as before. These services will in turn pass few parameters to the services of DLSI. With the help of these parameters, wrappers will fetch the details and priority of the users. These wrappers will be using the services of Search and Discovery module, Metadata Management services, and Access Management services. Users will see a totally integrated environment. They will see their digital library system just as before. In addition to that, they will find some extra link anchors on the document. These links serve to provide the supplemental information or arrange the information in the user preferred way. For this matter, the DLSI maintains basic user\u27s information and preferences. Other contributions include incorporating collaborative filtering for customizing large sets of links, and advance lexical analysis tool to identify the objects of interest in a document
