With the exponential growth of communication and information technologies, adaptation has
gained a significant attention as it becomes a key feature of service-based systems, allowing …

The intrinsic flexibility and dynamism of service-centric applications preclude their pre-
release validation and demand for suitable probes to monitor their behavior at run-time …

Abstract Service-based applications have to continuously and dynamically self-adapt in
order to timely react to changes in their context, as well as to efficiently accommodate for …

The advances in modern technology development and future technology changes dictate
new challenges and requirements to the engineering and provision of services and service …

The dynamic nature of the Internet poses various challenges to the successful execution of
composite Web services. Failures are samples of these challenges. It needs to be …

Abstract Service-based applications have been attracting a lot of attention from both
academia and industry in recent years. Therefore, as these applications need to operate in a …

Although adaptivity, the ability to adapt, is an important property of complex computing
systems, so far little thought has been given to its evaluation. In this paper we propose a …

Web services, service-oriented, and service-discovery architectures help developers solve
complex business cases, reduce costs, risks, and time-to-market. The task of developers is …

A computationally efficient distributed beamforming technique for multi-user relay networks
is developed. The channel state information is assumed to be known at the relays or …

The paper presents results from an empirical study of change requests in four releases of a
large-scale telecom system that is developed incrementally. The results show that earlier …
