Design by contract is a well-established paradigm in software engineering. Bertrand Meyer first introduced the rigorous distinction between the responsibilities of service provider and service consumer for fine grain software artifacts (classes). This paper considers service contracts in the context of service-oriented architecture for complex enterprise information infrastructures. Identifying...

This paper reports a case study of end-user control in delivery of web-based electronic services. The case study concentrates the adoption of a web-based electronic system being implemented in processing student’s admission applications on website. The end-user’s control interface provides information on the detail existing in the web-based electronic service. This insight into end-user synesis...

One of the main obstacles to the adoption of Wireless Sensor Networks (WSNs) outside the research community is the lack of high level mechanisms to easily program them. This problem affects distributed applications in general, and it has been replied by the Software Engineering community, which recently embraced Service Oriented Programming (SOP) as a powerful abstraction to ease development of...

Space is an unforgiving environment – one of harshest known to mankind. Yet, space is far less understood than other service environments in which DOD systems operate. It has been known to limit the useful life of satellites, with 20 to 25% of all mission failures being attributed to the effects of the space environment.[1] Since access to space is so costly, materials and components must funct...

This paper introduces a programming language for serviceoriented agents. Jadl++ combines the ease of use of scripting-languages with a state-of-the-art service oriented approach which allows the seamless integration of web-services. Furthermore, the language includes OWLbased ontologies for semantic descriptions of data and services, thus allowing agents to make intelligent decisions about serv...
