Component orientation and web services are two approaches for design and realization of complex web-based system. Both approaches allow for dynamic application adaptation as well as integration of enterprise application. Service-Oriented Systems Engineering represents a symbiosis of best practices in object-orientation, component-based development, distributed computing, and business process management. It provides integration of business and IT concerns. The annual Ph.D. Retreat of the Research School provides each member the opportunity to present his/her current state of their research and to give an outline of a prospective Ph.D. thesis. Due to the interdisciplinary structure of the research school, this technical report covers a wide range of topics. These include but are not limited to: Human Computer Interaction and Computer Vision as Service; Service-oriented Geovisualization Systems; Algorithm Engineering for Service-oriented Systems; Modeling and Verification of Self-adaptive Service-oriented Systems; Tools and Methods for Software Engineering in Service-oriented Systems; Security Engineering of Service-based IT Systems; Service-oriented Information Systems; Evolutionary Transition of Enterprise Applications to Service Orientation; Operating System Abstractions for Service-oriented Computing; and Services Specification, Composition, and Enactment.}, language = {en} } @article{LimanowskiLopesKecketal.2020, author = {Limanowski, Jakub and Lopes, Pedro and Keck, Janis and Baudisch, Patrick and Friston, Karl and Blankenburg, Felix}, title = {Action-dependent processing of touch in the human parietal operculum and posterior insula}, series = {Cerebral Cortex}, volume = {30}, journal = {Cerebral Cortex}, number = {2}, publisher = {Oxford University Press}, address = {Oxford}, issn = {1047-3211}, doi = {10.1093/cercor/bhz111}, pages = {607 -- 617}, year = {2020}, abstract = {Somatosensory input generated by one's actions (i.e., self-initiated body movements) is generally attenuated. Conversely, externally caused somatosensory input is enhanced, for example, during active touch and the haptic exploration of objects. Here, we used functional magnetic resonance imaging (fMRI) to ask how the brain accomplishes this delicate weighting of self-generated versus externally caused somatosensory components. Finger movements were either self-generated by our participants or induced by functional electrical stimulation (FES) of the same muscles. During half of the trials, electrotactile impulses were administered when the (actively or passively) moving finger reached a predefined flexion threshold. fMRI revealed an interaction effect in the contralateral posterior insular cortex (pIC), which responded more strongly to touch during self-generated than during FES-induced movements. A network analysis via dynamic causal modeling revealed that connectivity from the secondary somatosensory cortex via the pIC to the supplementary motor area was generally attenuated during self-generated relative to FES-induced movements-yet specifically enhanced by touch received during self-generated, but not FES-induced movements. Together, these results suggest a crucial role of the parietal operculum and the posterior insula in differentiating self-generated from externally caused somatosensory information received from one's moving limb.}, language = {en} } @misc{KovacsIonLopesetal.2019, author = {Kovacs, Robert and Ion, Alexandra and Lopes, Pedro and Oesterreich, Tim and Filter, Johannes and Otto, Philip and Arndt, Tobias and Ring, Nico and Witte, Melvin and Synytsia, Anton and Baudisch, Patrick}, title = {TrussFormer}, series = {The 31st Annual ACM Symposium on User Interface Software and Technology}, journal = {The 31st Annual ACM Symposium on User Interface Software and Technology}, publisher = {Association for Computing Machinery}, address = {New York}, isbn = {978-1-4503-5971-9}, doi = {10.1145/3290607.3311766}, pages = {1}, year = {2019}, abstract = {We present TrussFormer, an integrated end-to-end system that allows users to 3D print large-scale kinetic structures, i.e., structures that involve motion and deal with dynamic forces.
