As such, computer-aided tools have been recently used to assist in this task, but the challenge in the automatic identification of Parkinson's Disease still persists. In order to cope with this problem, we propose to employ Restricted Boltzmann Machines (RBMs) to learn features in an unsupervised fashion by analyzing images from handwriting exams, which aim at assessing the writing skills of potential individuals. These are one of the main symptoms of PD-prone people, since such kind of ability ends up being severely affected. We show that RBMs can learn proper features that help supervised classifiers in the task of automatic identification of PD patients, as well as one can obtain a more compact representation of the exam for the sake of storage and computational load purposes.}, language = {en} } @incollection{Skornia, author = {Skornia, Christoph}, title = {Sicherheit in der Cloud}, series = {IT-Sicherheit}, booktitle = {IT-Sicherheit}, editor = {Lang, Michael and L{\"o}hr, Hans and Angermeier, Daniel}, publisher = {Hanser}, address = {M{\"u}nchen}, isbn = {978-3-446-47223-5}, doi = {10.3139/9783446473478.015}, pages = {263 -- 278}, language = {de} } @incollection{HaugSchmidbauer, author = {Haug, Sonja and Schmidbauer, Simon}, title = {Integrationskonzepte und Messung von Integration auf kommunaler Ebene}, series = {Integration - Teilhabe und Zusammenleben in der Migrationsgesellschaft}, booktitle = {Integration - Teilhabe und Zusammenleben in der Migrationsgesellschaft}, editor = {Spieker, Michael and Hofmann, Christian}, publisher = {Nomos}, address = {Baden-Baden}, isbn = {9783748910558}, pages = {69 -- 84}, subject = {Soziale Integration}, language = {de} } @incollection{Weber, author = {Weber, Karsten}, title = {Robotik in der Pflege- und Gesundheitsversorgung}, series = {Genese und Folgen der Pflegerobotik}, booktitle = {Genese und Folgen der Pflegerobotik}, number = {196}, editor = {Hergesell, J. and Meister, M. and Maibaum, A.}, publisher = {Beltz/Juventa}, address = {Weinheim}, isbn = {978-3-7799-5243-5}, abstract = {Drei Ver{\"a}nderungen charakterisieren den demografischen Wandel in Deutschland: steigende durchschnittliche Lebenserwartung, der Anteil der Alten und Hochbetagten w{\"a}chst und der Anteil der j{\"u}ngeren Generationen schrumpft.

A specific feature of our software is its design as a component: the Alignment HOC, a Higher-Order Component that makes use of the latest Globus toolkit as grid middleware. Besides genome data, the Alignment HOC accepts plugin code for processing this data as its input, and contains all the required configuration to run the component on top of Globus, thus, freeing the non-grid-expert user from dealing with grid middleware. Instead of writing data distribution procedures and configuring the middleware appropriately for every new algorithm, Alignment HOC users reuse the existing component and only write application-specific plugins. To maintain plugins persistently in a reusable manner, we built a web-accessible plugin database with a comfortable administration GUI. The flexible component-based implementation makes it easy to study CPs in other databases (e.g. UniProt/Swiss-Prot) or to use an alignment algorithm different than the standard Needleman-Wunsch.

Components support developing applications on the Grid without taking all the technical details of the particular platform type into account (network communication, heterogeneity, etc.). The GCMenables a hierarchical composition of programpieces and HOCs enable the reuse of component code in the development of new applications by specifying application-specific operations in a program via code parameters. When a programmer is provided, e. g., with a compute farm HOC, only the independent worker tasks must be described. But, once an application exhibits data or control dependences, the trivial farm is no longer sufficient. Here, the power of loop parallelization tools, like LooPo, comes into play: by embedding LooPo into a HOC, we show that these two technologies in combination facilitate the automatic transformation of a sequential loop nest with complex dependences (supplied by the user as a HOC parameter) into an ordered task graph, which can be processed on the Grid in parallel. This technique can significantly simplify GCM-based systems which combine multiple HOCs and other components.

HOCs are parallel programming components, made accessible on the grid via Web services that use a special class loader enabling code mobility: executable code can be uploaded to a HOC, allowing one to customize the HOC. Fractal simplifies the composition of components and the ProActive library offers a generator for automatically creating Web services from components composed with Fractal, as long as all the parameters of these services have primitive types. Taking all the advantages of HOCs, ProActive and Fractal together, the obvious conclusion is that composing HOCs using Fractal and automatically exposing them as Web services on the grid via ProActive minimizes the required efforts for building complex grid systems.

We discuss three optimizations: 1) a lookahead mechanism that allows to process multiple tasks concurrently at each grid server and thereby increases the overall degree of parallelism, 2) a lazy taskbinding technique that reduces interactions between grid servers and the task dispatcher, and 3) dynamic improvements that optimize the collecting of results and the work-load balancing.

Further it is demonstrated that MRI of experimental HFOV is feasible and that Hyperpolarized 3He allows for imaging the gas re-distribution inside the lung.

Today's and future embedded systems require increasing performance while being more energy efficient. Moreover, the functional safety for these embedded systems has to be improved or developed completely new. In this chapter, we first address the challenges of embedded multi-core real-time systems. To raise the resilience of such systems we use the deadlock-free synchronization model of Block et al. (A flexible real-time locking protocol for multiprocessors. 2012 IEEE international conference on embedded and real-time computing systems and applications, vol 0, pp 47-56, 2007). The metric mean Normalized Blocking Time (mNBT) is hereby used to measure the timing effects of the blocking behavior of strongly interacting tasks. In a second step, we present a model-based approach to map the tasks of an embedded real-time system to the cores of a multi-core processor. Moreover, we derive an execution time model from runtime measurements of software functions. This information is then used to perform precise probabilistic simulations of different task-to-core mappings and evaluate them with regard to task response times, inter-task blocking overhead and load distribution. Subsequently, we integrate the probabilistic simulation within an optimization technique to systematically improve the task-to-core mapping. We conclude with a case-study, where we demonstrate the effectiveness of the presented approach by optimizing the task-to-core mapping of a practical automotive powertrain system.}, language = {en} } @incollection{KopperStrahringerWestner, author = {Kopper, Andreas and Strahringer, Susanne and Westner, Markus}, title = {Kontrollierte Nutzung von Schatten-IT}, series = {IT-GRC-Management - Governance, Risk und Compliance}, booktitle = {IT-GRC-Management - Governance, Risk und Compliance}, publisher = {Springer Vieweg}, address = {Wiesbaden}, isbn = {978-3-658-20058-9}, doi = {10.1007/978-3-658-20059-6_9}, pages = {129 -- 150}, abstract = {Basierend auf einer systematischen und umfangreichen Analyse von Praxisbeitr{\"a}gen zum Thema Schatten-IT und einer Interviewstudie mit 16 IT-F{\"u}hrungskr{\"a}ften beschreibt der vorliegende Artikel Governance-Aspekte zu diesem Ph{\"a}nomen.
