Summary form only given. Today's complex service-oriented systems comprise humans and software services spanning multiple organizations. These systems are highly dynamic because not only services, processes and teams are diverse but also they constantly evolve. Therefore, these systems introduce many challenges on how to adapt services, processes and teams to changing situations. In this keynote talk,...
Complex motion makes consecutive frames experience dramatic change, and thus becomes a barrier to object-tracking. Three factors contribute to more complexity of motion: longer sampling period,an moving object with complex appearance and nonrestraint movement, occlusion, which causes mean shift algorithm losing its target due to too low a Bhattacharyya coefficient. To treat it, mean shift algorithm...
Due to the increasing complexity of Web systems, security testing is becoming a critical activity to guarantee the respect of such systems to their security requirements. To challenge this issue, we rely in this paper on model based active testing. We first specify the Web system behavior using IF formalism. Second, we integrate security rules -modeled in Nomad language- within this IF model using...
