Service-oriented computing allows new applications to be developed by using and/or combining services offered by different organizations. Service composition can be applied when a client request cannot be satisfied by any individual service. In this case, the creation of a composite service from a number of available services could be pursued. This composite service should comply with the clien...

This paper proposes an approach to dynamically reconfiguring service-oriented applications from a business perspective: CAFISEadapt, which defines both business-level and software-level change operations to respectively express changes in the business domain and the software domain. Utilizing the convergence of these two level change operations, the approach expects application changes can be a...

Risk/return management has not only evolved as one of the key success factors for enterprises especially in the financial services industry, but is in the times of the financial crisis crucial for the survival of a company. It demands powerful and at the same time flexible computational resources making it an almost ideal application for service-oriented computing concepts. An essential charact...

Illuminated manuscripts of medieval music contain rich decorations in addition to handwritten neumatic notation. Our project with composer Philippe Leroux investigates the use of such handwritten symbols during the composition of his piece Quid sit musicus. We introduce pOM, an interactive paper application and a library for the OpenMusic computer-aided composition environment which links pen g...

The development of new Web services by composition of existing ones is becoming a widespread approach to realise business-to-business collaborations. The composite services obtained in this way are then eventually used in other compositions. Given the dynamic nature of the Web, this recursive composition of services rapidly leads to intricate dependencies between them. On the other hand, busine...

Computer aided design and computer aided modeling tools are becoming increasingly important in the design and performance evaluation of communication systems. In this work, we report on the computer simulation modeling study of terrestrial digital microwave radio transmission, using Block Oriented System Simulator package (BOSS). The work concentrates on semi-analytical error rate evaluation in...

The object-oriented approach has evolved as a software design and programming method. It was later adapted to systems analysis as a modeling method. Modeling in systems analysis is used to create a representation of the organizational domain for which the information system is developed. Such a model is termed an enterprise model. A modeling method comprises a modeling technique and a modeling ...

In spite of the widely recognized benefits of applying Service Oriented Architecture (SOA) to design enterprise-scale software systems, its actual application practice is not always a success. One major reason is the lack of a systematic engineering process and tool supported by reusable architectural artifacts. Toward this ultimate goal, this paper proposes a new method of architectural buildi...

Service Oriented Architectures are increasingly being used to achieve interoperability among heterogeneous systems. SOAs help developers to integrate different architectures in order to reuse legacy systems and extend software boundaries. Semantics could improve SOA features adding a common understanding of the resources shared among different systems. Model Driven Development could be useful t...
