We argue that grid programming is still too complex because of the big gap between the currently used and anticipated grid middleware, (e.g., Globus or WSRF) and the application level. We suggest that this gap needs to be closed in future-generation grids and propose a novel approach to bridging the gap by using Higher-Order Components (HOCs) — recurring patterns of parallel behaviour that are provided to the user as program building blocks with pre-packaged implementation and middleware setup. The presentation is illustrated with a simple case study of computing fractal images. Our experiments demonstrate that HOCs can simplify grid application programming significantly, without serious performance loss.}, language = {en} } @incollection{FrikelHaltmeier, author = {Frikel, J{\"u}rgen and Haltmeier, Markus}, title = {Sparse Regularization of Inverse Problems by Operator-Adapted Frame Thresholding}, series = {Mathematics of Wave Phenomena}, booktitle = {Mathematics of Wave Phenomena}, editor = {D{\"o}rfler, Willy and Hochbruck, Marlis and Hundertmark, Dirk and Reichel, Wolfgang and Rieder, Andreas}, edition = {1st ed.}, publisher = {Birkh{\"a}user; Springer International Publishing}, address = {Cham}, isbn = {978-3-030-47173-6}, doi = {10.1007/978-3-030-47174-3_10}, pages = {163 -- 178}, abstract = {We analyze sparse frame based regularization of inverse problems by means of a diagonal frame decomposition (DFD) for the forward operator, which generalizes the SVD. The DFD allows to define a non-iterative (direct) operator-adapted frame thresholding approach which we show to provide a convergent regularization method with linear convergence rates. These results will be compared to the well-known analysis and synthesis variants of sparse ℓ1-regularization which are usually implemented thorough iterative schemes. If the frame is a basis (non-redundant case), the three versions of sparse regularization, namely synthesis and analysis variants of ℓ1-regularization as well as the DFD thresholding are equivalent. However, in the redundant case, those three approaches are pairwise different.}, language = {en} } @incollection{Weber, author = {Weber, Karsten}, title = {Closing the Digital Divide - lokal, nicht global}, series = {Technology Assessment in der Weltgesellschaft}, booktitle = {Technology Assessment in der Weltgesellschaft}, editor = {Bora, A. and Br{\"o}chler, S. and Decker, Michael}, publisher = {Edition Sigma}, address = {Berlin}, pages = {177 -- 190}, language = {de} } @incollection{Weber, author = {Weber, Karsten}, title = {New Mobile Devices and Surveillance: Questions Concerning Epistemology and Some New Challenges for Privacy and Data Protection}, series = {Postmodern Quests in Applied Philosophy}, booktitle = {Postmodern Quests in Applied Philosophy}, editor = {Kolb, David and Salman, Ahmed Shaikh and Druzin, Bryan}, publisher = {Editura Lumen}, address = {Iasi}, language = {en} } @incollection{WeberDrueekeSchulz, author = {Weber, Karsten and Dr{\"u}eke, Ricarda and Schulz, Axel}, title = {Mobile ICT in public spaces and its impact on privacy}, series = {Societies and Cities in the Age of Instant Access}, volume = {88}, booktitle = {Societies and Cities in the Age of Instant Access}, editor = {Miller, Harvey J.}, publisher = {Springer}, address = {Berlin}, doi = {10.1007/1-4020-5427-0_13}, pages = {197 -- 208}, language = {en} } @incollection{WeberDrueekeSchulz, author = {Weber, Karsten and Dr{\"u}eke, Ricarda and Schulz, Axel}, title = {Mobiler Wissenszugang: Digital Rights Management vs. Privacy}, series = {Wissensorganisation und Verantwortung.

In modern health services data protection is essential. But there are also other important security objectives, such as integrity and authenticity of medical data and health services, as their breach can potentially lead to life threatening conditions. State of the art security mechanisms are necessary to protect medical data and services and prevent attacks known as "hacking". They should include in particular cryptography, as you can usually rely on mathematics, more than in software security and access control mechanisms. As patients normally cannot assess the security of a service, security audits or certifications of health services should be provided to generate trust and confidence.}, subject = {Gesundheitswesen}, language = {en} } @incollection{Raptis, author = {Raptis, Georgios}, title = {Gew{\"a}hrleistung der IT-Sicherheit bei vernetzten Implantaten}, series = {Biomedizinische Technik: Vernetzte und intelligente Implantate}, booktitle = {Biomedizinische Technik: Vernetzte und intelligente Implantate}, editor = {Marschner, Uwe and Clasbrummel, Bernhard and Dehm, Johannes}, publisher = {Walter de Gruyter}, isbn = {978-3-11-034927-6}, pages = {182 -- 192}, subject = {Implantat}, language = {de} } @incollection{MuellerFalter, author = {M{\"u}ller, Andreas and Falter, Thomas}, title = {Sechs F{\"u}hrungsperspektiven f{\"u}r die digitale Transformation - Welche Dashboards das Ver{\"a}nderungsmanagement in digitalen Zeiten unterst{\"u}tzen k{\"o}nnen}, series = {Arbeitskulturen im Wandel}, booktitle = {Arbeitskulturen im Wandel}, editor = {W{\"o}rwag, Sebastian and Cloots, Alexandra}, publisher = {Springer Gabler}, address = {Wiesbaden}, isbn = {978-3-658-30450-8}, doi = {10.1007/978-3-658-30451-5_12}, pages = {239 -- 257}, abstract = {W{\"a}hrend KPIs und Dashboards in großer Zahl f{\"u}r den Betrieb eines Unternehmens im eingeschwungenen Zustand zur Verf{\"u}gung stehen, scheint es insbesondere in der digitalen Transformation besonders schwierig zu sein, Orientierung zu behalten und zu vermitteln.
