The National Nuclear Data Center (NNDC) provides nuclear data through 40 websites, many of which are being updated to make easier find. most visible change is a site-wide navigation menu that links the NNDC’s most-visited databases. Evaluated Structure File (ENSDF) front page now also has chart interface for visual exploration its data. NuDat 3.0 faster, smoother, and feature-rich interactive C...

  Response time is one of the critical web service quality dimensions. It refers to how long it takes that a web service responds to request of a user. In order to manage the response time, pricing schemes can work as an efficient access control mechanism. In this paper, we study competition between two providers offering functionally same web services where there is a monopoly service provider...

Emergency management/Emergency service is a compelling domain for applying GIS Web Service. GIS Web Service expands the further development of GIS. A Web service is described using XML-standards like the WSDL (Web Service Description Language). Web Services, are different from Web applications, don’t require people to use; but software applications to call. Thus, the Web service does not have a...

This paper concentrates on the issue of matchmaking in the context of web services. It provides a brief review of the difference between directory services and matchmaking facilities and explains why directories such as UDDI are important but insufficient for web services and need to be complemented with advanced matchmaking facilities. It discusses the requirements that web services place on m...

W. De Pauw M. Lei E. Pring L. Villard M. Arnold J. F. Morar The Web Services standard is becoming the lingua franca for loosely coupled distributed applications. As the number of nodes and the complexity of these applications grow over the coming years, it will become more challenging for developers to understand, debug, and optimize them. In this paper, we describe Web Services Navigator, a vi...

In this paper, a model is presented which allows the composition of web services by means of a special web service, named WSInterConnect. Such a service might be used in a portal environment to allow interactive services lookup and creation of permanent composed services in the design stage, and for efficiently resolving missing parameters during the runtime of a process. The portal integration...

The Web services’ standards have some limits: UDDI provides a simple classification of Web services by sectors and WSDL doesn’t provide any Web services topologies’ description. Since these limits can influence Web services research’s results’ quality, this work aims to propose an approach that permits an optimised classification and a pertinent research of Web services. For that, we made some ...
