Web service processes currently lack monitoring and dynamic (runtime) adaptation mechanisms. In highly dynamic processes, services frequently need to be exchanged due to a variety of reasons. In this paper we present VieDAME, a system which allows monitoring of BPEL processes according to Quality of Service (QoS) attributes and replacement of existing(More)
VieDAME is a tool for monitoring and dynamic service adaptation of BPEL processes. The tool monitors partner service interaction to compute Quality of Service (QoS) data and performs dynamic service adaptation based on various available service selection strategies, such as availability or response time. The service adaptation happens transparently at(More)
Early studies with high-dose chemotherapy for treatment of relapsed cerebral PNET had shown modest efficacy but considerable toxicity. The HIT97 national trial tested a nonrandomized but stratified relapse protocol using either intensive chemotherapy, potentially high dose, or oral chemotherapy. 72 patients (59 disseminated) whose primary treatment had been(More)
We present an event-based monitoring approach for service composition infrastructures. While existing approaches mostly monitor these infrastructures in isolation, we provide a holistic monitoring approach by leveraging Complex Event Processing (CEP) techniques. The goal is to avoid fragmentation of monitoring data across different subsystems in large(More)
An antiserum was raised against a fusion protein containing the C-terminal half of the protein (P3) encoded by the satellite RNA of grapevine fanleaf virus (GFLV; F13 isolate) and the N-terminal portion of the CI repressor of phage lambda. This antiserum specifically recognized P3 synthesized in the in vitro wheatgerm translation system and also in infected(More)
—We propose a domain-specific service selection mechanism and system implementation to address the issue of runtime adaptation of composite services that implement mission-critical business processes. To this end, we leverage quality of service (QoS) as a means to specify rigid dependability requirements. QoS does not include only common attributes such as(More)
