In particular, windgas in the heat market is discussed in the utilization cascade of wind energy. The new "power-to-gas" concept opens up completely new possibilities for the integration of renewable energies and for coupling the electricity and gas grids. The Sabatier process, which has been known for 100 years, was first developed for this purpose in 2008 under the leadership of the Center for Solar Energy and Hydrogen Research and Fraunhofer IWES (formerly ISET) with electrolysis to create the "power-to-gas" concept for energy storage. A first pilot plant was built by ZSW Stuttgart on behalf of SolarFuel in 2009. This plant proves the technical feasibility of the new technology. Renewable gas is stored, transported and used as required as control and reserve energy via reconversion, e.g. in combined cycle power plants. In this way, decentrally generated renewable electricity is converted into a CO2 -neutral energy carrier with high energy density. The key advantage of renewable methane is the use of existing infrastructure such as gas grids, gas storage and end-use equipment for the integration of renewable energy. Technologies for natural gas are state of the art and commercially available. Methane also has three times the energy density of hydrogen.}, language = {en} } @incollection{Haug, author = {Haug, Sonja}, title = {Migration aus Mittel- und Osteuropa nach Deutschland}, series = {Migration in Europa}, booktitle = {Migration in Europa}, editor = {Haug, Sonja and Swiaczny, Frank}, organization = {Bundesinstitut f{\"u}r Bev{\"o}lkerungsforschung}, pages = {133 -- 151}, abstract = {Im Zuge der EU-Ost-Erweiterung sind im Mai 2004 zehn L{\"a}nder der EU beigetreten.

Among the participating projects, the one presented herein focuses on the development of a smart expansion joint, to assess the traffic parameters on site. This is achieved by measuring velocity and weight of crossing vehicles. In reference measurements, performed with a three-axle truck and a typical tractor semi-trailer combination with five axles in total, it was shown that the interaction between the vehicle and the expansion joint is highly dynamic and depends on several factors. To get more insight into this dynamic problem, a virtual test rig was set up. Although nearly all vehicle parameters had to be estimated, the simulation results conform very well with the measurements and are robust to vehicle parameter variations. In addition, they indicate a significant influence of the expansion joint dynamic to the peak values of the measured wheel loads, in particular on higher driving velocities. By compensating the relevant dynamic effects in the measurements, a "smart" data processing algorithm makes it possible to determine the actual vehicle weights in random traffic with reliability and appropriate accuracy.}, language = {en} } @incollection{FinckhNiedermeierSchmittetal., author = {Finckh, Wolfgang and Niedermeier, Roland and Schmitt, Alexander and Zilch, Konrad}, title = {Beispiel 3: Verst{\"a}rkung eines Plattenbalkens mit aufgeklebten CFK-Lamellen}, series = {Erl{\"a}uterungen und Beispiele zur DAfStb-Richtlinie "Verst{\"a}rken von Betonbauteilen mit geklebter Bewehrung"}, booktitle = {Erl{\"a}uterungen und Beispiele zur DAfStb-Richtlinie "Verst{\"a}rken von Betonbauteilen mit geklebter Bewehrung"}, editor = {Zilch, Konrad}, publisher = {Beuth}, address = {Berlin}, isbn = {978-3-410-65245-8}, issn = {0171-7197}, pages = {83 -- 108}, subject = {Betonbauteil}, language = {de} } @article{LinnerSeelingerVogtLydiaetal., author = {Linner, Thomas and Seelinger, Anja and Vogt Lydia, and Sch{\"a}pers Barbara, and Steinb{\"o}ck, Martina and Krewer, Carmen and Bock, Thomas}, title = {REACH: Solutions for Technology-Based Prevention and Empowerment for Older People and their Caregivers}, series = {Journal of Population Ageing: Special Issue on responsive engagement of older persons promoting activity and customized healthcare}, volume = {13}, journal = {Journal of Population Ageing: Special Issue on responsive engagement of older persons promoting activity and customized healthcare}, number = {1}, publisher = {Springer Nature}, doi = {10.1007/s12062-020-09268-5}, pages = {131 -- 137}, abstract = {REACH stands for "Responsive Engagement of the Elderly Promoting Activity and Customized Healthcare".

With increasing complexity of industrial products, also BOMs become more complex and thus prone to errors, for example when the individual parts of a product are changed during the product development process. Frequently, these Bill of Materials errors have to be identified manually or by using simple, rule-based schemes. In this paper, we provide a technical background of BOMs, showing the intricacy of temporal BOMs errors in an industrial product development process. The work of other authors, which focused on association mining and tree reconciliation to detect Bill of Materials errors, is analysed. We found that there is currently no system being able to prescribe where in a Bill of Materials and when in the product development process, errors are probable to occur. Also, Machine Learning (ML) methods have not been applied yet. Based on these findings, we formalize the notions Bill of Materials and Bill of Materials errors. Furthermore, we present a deterministic distance measure for BOMS. We provide an answer to the main question of how to represent a Bill of Materials for Machine Learning tasks by solving the orthogonal Procrustes problem for dynamic, hierarchical datasets. Then, we describe an isolation forest based approach to temporal anomaly detection, which points at potential errors in a Bill of Materials at a specific timestamp. Furthermore, we apply Machine Learning and present a multi-output Multi Layer Perceptron for the prediction of temporal Bill of Materials errors. The model predicts where and at which point of time Bill of Materials errors are probable to occur, which renders it a prescriptive system. Eventually, we optimize the performance of our model using contextualization via -means clustering. Finally, we apply our prescriptive pipeline to a real world dataset and show its superiority to existing methods using a qualitative comparison.}, language = {en} } @article{SchwabPogrebnojFreundetal., author = {Schwab, E. and Pogrebnoj, S. and Freund, M. and Flossmann, F. and Vogl, Stefanie and Frommolt, K.-H.}, title = {Automated bat call classification using deep convolutional neural networks}, series = {Bioacoustics}, journal = {Bioacoustics}, publisher = {Taylor \& Francis}, doi = {10.1080/09524622.2022.2050816}, pages = {1 -- 16}, abstract = {Identification of bats is most practically done by exploiting the characteristic features of their echolocation calls.

Optical excitation triggers a chain of relaxation processes, causing rapid lattice heating, generation and propagation of stress/strain waves into the bulk and eventual anharmonic decay of coherent acoustic phonons into the thermal bath of the solid. While the first steps of carrier relaxation, excitation and decay of Raman-active optical phonons have been in the past characterized optically at surfaces, the bulk acoustic dynamics at longer times has not. We measure length scales of lattice excitation, thereby detecting ultrafast heat diffusion via fast electrons, coherent acoustic pulse propagation into the bulk or across buried interfaces and anharmonic damping of non-equilibrium acoustic phonons.

Finally, the author examines determinants of IS offshore project success in German companies based on a statistical analysis of 304 projects using structural equation modeling (PLS).}, subject = {Informationssystem}, language = {en} } @techreport{Westner, type = {Working Paper}, author = {Westner, Markus}, title = {Information systems offshoring}, address = {Dresden}, subject = {Informationstechnik}, language = {en} } @incollection{Westner, author = {Westner, Markus}, title = {{\"U}bersicht {\"u}ber aktuelle Weblog-Skripte und -Services}, series = {Weblogs professionell : Grundlagen, Konzepte und Praxis im unternehmerischen Umfeld}, booktitle = {Weblogs professionell : Grundlagen, Konzepte und Praxis im unternehmerischen Umfeld}, editor = {Picot, Arnold and Fischer, Tim}, isbn = {978-3898643757}, pages = {175 -- 190}, subject = {Kommunikation}, language = {de} } @inproceedings{WestnerStrahringer, author = {Westner, Markus and Strahringer, Susanne}, title = {Current state of IS offshoring research}, series = {M{\"a}ki{\"o}, Juho; Betz, Stefanie; Stephan, Rolf (Eds.): Offshoring of software development.

Relying on a sample of 304 projects conducted at various industry sectors and companies, results show that IS offshoring primarily occurs in sectors Telecommunications and IT at large corporations. Cost reduction is the main reason for going offshore and offshore projects are executed as part of a larger program at companies. Noticeably, most projects are delivered from India. Additionally, neither captive offshoring nor offshore outsourcing dominates as a de-livery option. Comparing different project subgroups regarding project success, the results reveal that projects delivered by an internal or partially owned service provider are more successful. Other project characteristics such as a project's embedded-ness in a larger offshoring program, a project's size, or a project's offshoring degree in terms of relatively offshored labor hours show few significant differences. The paper addresses the paucity of empirical research on the current state of the IS offshoring phenomenon in Germany.}, subject = {Informationsmanagement}, language = {en} } @incollection{Weber, author = {Weber, Karsten}, title = {Bottom-Up Mixed-Reality: Emergente Entwicklung, Unkontrollierbarkeit und soziale Konsequenzen}, series = {Be-greifbare Interaktionen - Der allgegenw{\"a}rtige Computer: Touchscreens, Wearables, Tangibles und Ubiquitous Computing}, booktitle = {Be-greifbare Interaktionen - Der allgegenw{\"a}rtige Computer: Touchscreens, Wearables, Tangibles und Ubiquitous Computing}, editor = {Robben, B. and Schelhowe, H.}, publisher = {Transcript}, address = {Bielefeld}, doi = {10.14361/transcript.9783839420058.347}, pages = {347 -- 366}, language = {de} } @article{OrwatRaabeBuchmannetal., author = {Orwat, Carsten and Raabe, Oliver and Buchmann, Erik and Anandasivam, Arun and Freytag, Johan-Christoph and Helberger, Natali and Ishii, Kei and Lutterbeck, Bernd and Neumann, Dirk and Otter, Thomas and Pallas, Frank and Reussner, Ralf and Sester, Peter and Weber, Karsten and Werle, Raymund}, title = {Software als Institution und ihre Gestaltbarkeit}, series = {Informatik-Spektrum}, volume = {33}, journal = {Informatik-Spektrum}, number = {6}, doi = {10.1007/s00287-009-0404-z}, pages = {626 -- 633}, abstract = {Software regelt immer mehr zwischenmenschliche Interaktionen. {\"U}blicherweise werden die Funktionsmechanismen, Wirkungen und Gestaltungsoptionen von Regeln in der Institutionenforschung behandelt.

Einerseits wurde begr{\"u}ßt, dass sich die GI verbindlich an ein ethisches Regelwerk bindet und dadurch ihren Mitgliedern einen Leitfaden an die Hand gibt, um in Konfliktsituationen besser entscheiden zu k{\"o}nnen. Andererseits wurde bem{\"a}ngelt, dass die Ethischen Leitlinien Forderungen stellten, die f{\"u}r professionelles Handeln unabdingbar seien und deshalb keine ethischen Anspr{\"u}che darstellten. Des Weiteren wurde kritisiert, dass die Ethischen Leitlinien zu sehr im Abstrakten verharrten und deshalb keine konkrete Handlungsanweisung geben k{\"o}nnten. Die fachlichen und {\"u}berfachlichen Anforderungen wurden zuweilen als zu anspruchsvoll empfunden. Einige dieser Kritikpunkte sind sicherlich berechtigt. Im November 2001 begann der Arbeitskreis „Informatik und Verantwortung" im Fachbereich Informatik und Gesellschaft (IuG) mit der {\"U}berarbeitung der Ethischen Leitlinien. Der hier vorgelegte Entwurf greift einige dieser Kritikpunkte auf. Seine Publikation soll eine breitere Diskussion innerhalb der GI erm{\"o}glichen. Die Autorinnen und Autoren dieses Entwurfs freuen sich auf diese Auseinandersetzung, die in der letzten Sitzung des Arbeitskreises durch den Vertreter der Selbst{\"a}ndigen in der GI mit dem Hinweis begonnen wurde, dass den Leitlinien ein Berufsbild zugrunde liegt, in dem die Selbst{\"a}ndigen nicht vorkommen.
