Abstract. Workflow technology is an emerging paradigm for systematic modeling and orchestration of job flow for enterprise and scientific applications. This paper introduces BPEL4Job, a BPEL-based design for fault handling of job flow in a distributed computing environment. The features of the proposed design include: a two-stage approach for job flow modeling that separates base flow structure from fault-handling policy, a generic job proxy that isolates the interaction complexity between the flow engine and the job scheduler, and a method for migrating flow instances between different flow engines for fault handling in a distributed system. An implementation of the design based on a set of industrial products from IBM is presented and validated using a Montage application. 1

Abstract- Governmental institutions all over the world are trying to increase the level of security of their countries emphasizing the usage Information Technology solutions. We believe that Cloud Computing may strongly help Homeland Security, since it offers a very flexible support for organizing and managing heterogeneous systems, providing huge amount of processing, storing and sensing resources. In this work we introduce a new Cloud architecture able to virtualize different types of sensing environments in virtual sensing elements, logically belonging to Cooperating Clouds. It

After crossing a finish line, one should not miss the opportunity to look back and revive the memory of all the good things that happened along the way. During my time in Kaiserslautern, I had the privilege to work with many smart, creative, and valuable persons, which supported my work and enriched my life in manifold ways. First and foremost, I want to express my deepest gratitude to my advisor Prof. Theo Härder. His offer to join the DBIS research group opened me the door to an experience of personal and professional development from which I will benefit the rest of my life. He gave me the freedom to pursue my own research and I could always count on his support and learn from his great experience. At this point, I also want to thank Prof. Wolfgang Lehner and Jun.-Prof. Roland Meyer for accepting the role as second examiner and head of the examination board, respectively. Their feedback and interest in my work before, during, and after my defense have been a

Workflow design is often an effort of distributed and heterogeneous teams, thus making tool support for collaboration a necessity. We present a novel concept of collaborative work-flow design which combines cooperation and workflow model analysis. Workflow analysis is simplified using workflow metrics, which help identifying problematic aspects of the workflow model. Our findings are implemented in a collaborative workflow design system, which is easily accessible on the Web, but provides a desktop like user experience.
