Differing perspectives, processes, methods, tools, vocabularies, and standards are problems that arise in this context. We present an approach to support bringing together disciplines based on a common body of knowledge (CBK), in which knowledge from different disciplines is collected, integrated, and structured. The novelty of our approach is twofold: first, it introduces a CBK ontology, which allows one to semantically enrich contents in order to be able to query the CBK in a more elaborate way afterwards. Second, it heavily relies on user participation in building up a CBK, making use of the Semantic MediaWiki as a platform to support collaborative writing. The CBK ontology is backed by a conceptual framework, consisting of concepts to structure the knowledge, to provide access options to it, and to build up a common terminology. To ensure a high quality of the provided contents and to sustain the community's commitment, we further present organizational means as part of our approach. We demonstrate our work using the example of a Network of Excellence EU project, which aims at bringing together researchers and practitioners from services computing, security and software engineering.}, language = {en} } @incollection{SiemsSimonDinkeletal.2011, author = {Siems, Tanja and Simon, Katharina and Dinkel, Arnulf and Musall, Eike}, title = {Stadtbauprojekt Masdar}, series = {Nullenergiegeb{\"a}ude}, booktitle = {Nullenergiegeb{\"a}ude}, editor = {Voss, Karsten and Musall, Eike}, publisher = {Detail, Institut f{\"u}r internationale Architektur-Dokumentation}, address = {M{\"u}nchen}, isbn = {978-3-920034-50-8}, pages = {108 -- 113}, year = {2011}, language = {de} } @incollection{SkodaSteffensBuechel2011, author = {Skoda, Sabrina and Steffens, Jochen and B{\"u}chel, Joachim}, title = {Untersuchungen zum Einfluss von Beschleunigungskr{\"a}ften auf die Ger{\"a}uschbewertung im Fahrzeuginnenraum}, series = {5.

This includes both the creative design process and the development of suitable methods for the evaluation of target sounds by trial participants. The main difference between e-car sound surveys and those carried out on familiar sound categories is the potential consumer's lack of experience with electric vehicles. Thus the consumer has no, or very unspecific, expectations in this regard. Several studies have consequently shown that many subjects have to construct their personal frame of reference for evaluation within the listening experiment. However, this is possibly at odds with experience-based expectations relating to the sounds of conventional combustion engines. The result is a conflict of objectives between the traditional and the modern, familiarity and strangeness and not least between driving freedom and ecological awareness. In this context, the authenticity of the sound and the subjective interpretability of the sound information also appear as moderator variables. Moreover, associations with other vehicle categories, for example streetcars, also influence the perceived sound quality. In the course of this contribution, these factors will be expounded and their influence on the evaluation of interior noise discussed.}, language = {en} } @inproceedings{SteffensSchulteFortkampBeckerSchweitzer2011, author = {Steffens, Jochen and Schulte-Fortkamp, Brigitte and Becker-Schweitzer, J{\"o}rg}, title = {Design of domestic soundscapes - Evaluation of household appliances in laboratory and reality}, series = {Proceedings of Forum Acusticum 2011}, booktitle = {Proceedings of Forum Acusticum 2011}, publisher = {Spanish Acoustical Society}, address = {Madrid}, isbn = {9788469415207}, year = {2011}, language = {en} } @inproceedings{StuhlsatzMeyerEybenetal.2011, author = {Stuhlsatz, Andr{\´e} and Meyer, Christine and Eyben, Florian and Zielke, Thomas and Meier, Gunter and Schuller, Bjorn}, title = {Deep neural networks for acoustic emotion recognition: Raising the benchmarks}, series = {2011 IEEE International Conference on Acoustics, Speech and Signal Processing (ICASSP)}, booktitle = {2011 IEEE International Conference on Acoustics, Speech and Signal Processing (ICASSP)}, publisher = {IEEE}, doi = {10.1109/ICASSP.2011.5947651}, pages = {5688 -- 5691}, year = {2011}, abstract = {Deep Neural Networks (DNNs) denote multilayer artificial neural networks with more than one hidden layer and millions of free parameters. We propose a Generalized Discriminant Analysis (GerDA) based on DNNs to learn discriminative features of low dimension optimized with respect to a fast classification from a large set of acoustic features for emotion recognition. On nine frequently used emotional speech corpora, we compare the performance of GerDA features and their subsequent linear classification with previously reported benchmarks obtained using the same set of acoustic features classified by Support Vector Machines (SVMs). Our results impressively show that low-dimensional GerDA features capture hidden information from the acoustic features leading to a significantly raised unweighted average recall and considerably raised weighted average recall.}, language = {en} } @article{StuhrmannHuberKaes2011, author = {Stuhrmann, Bj{\"o}rn and Huber, Florian and K{\"a}s, Josef}, title = {Robust organizational principles of protrusive biopolymer networks in migrating living cells}, series = {Plos One}, volume = {6}, journal = {Plos One}, number = {1}, publisher = {Public Library of Science (PLoS)}, issn = {1932-6203}, doi = {10.1371/journal.pone.0014471}, url = {http://nbn-resolving.de/urn:nbn:de:hbz:due62-opus-34901}, year = {2011}, abstract = {Cell migration is associated with the dynamic protrusion of a thin actin-based cytoskeletal extension at the cell front, which has been shown to consist of two different substructures, the leading lamellipodium and the subsequent lamellum. While the formation of the lamellipodium is increasingly well understood, organizational principles underlying the emergence of the lamellum are just beginning to be unraveled. We report here on a 1D mathematical model which describes the reaction-diffusion processes of a polarized actin network in steady state, and reproduces essential characteristics of the lamellipodium-lamellum system. We observe a steep gradient in filament lengths at the protruding edge, a local depolymerization maximum a few microns behind the edge, as well as a differential dominance of the network destabilizer ADF/cofilin and the stabilizer tropomyosin. We identify simple and robust organizational principles giving rise to the derived network characteristics, uncoupled from the specifics of any molecular implementation, and thus plausibly valid across cell types. An analysis of network length dependence on physico-chemical system parameters implies that to limit array treadmilling to cellular dimensions, network growth has to be truncated by mechanisms other than aging-induced depolymerization, e.g., by myosin-associated network dissociation at the transition to the cell body. Our work contributes to the analytical understanding of the cytoskeletal extension's bisection into lamellipodium and lamellum and sheds light on how cells organize their molecular machinery to achieve motility.}, language = {en} }
