Unfortunately, mounts and joints tend to fail when trying to fabricate a model on a different laser cutter or from a different material. The reason for this lies in the way mounts and joints hold objects in place, which is by forcing them into slightly smaller openings. Such "press fit" mechanisms unfortunately are susceptible to the small changes in diameter that occur when switching to a machine that removes more or less material ("kerf"), as well as to changes in stiffness, as they occur when switching to a different material. We present a software tool called springFit that resolves this problem by replacing the problematic press fit-based mounts and joints with what we call cantilever-based mounts and joints. A cantilever spring is simply a long thin piece of material that pushes against the object to be held. Unlike press fits, cantilever springs are robust against variations in kerf and material; they can even handle very high variations, simply by using longer springs. SpringFit converts models in the form of 2D cutting plans by replacing all contained mounts, notch joints, finger joints, and t-joints. In our technical evaluation, we used springFit to convert 14 models downloaded from the web.}, language = {en} } @misc{RodriguezSillkeSteinhoffBojarskietal.2019, author = {Rodriguez-Sillke, Yasmina and Steinhoff, U. and Bojarski, Christian and Lissner, Donata and Schumann, Michael and Branchi, F. and Siegmund, Britta and Glauben, Rainer}, title = {Deep immune profiling of human Peyer´s Patches in patients of inflammatory bowel diseases}, series = {European journal of immunology}, volume = {49}, journal = {European journal of immunology}, publisher = {Wiley}, address = {Weinheim}, issn = {0014-2980}, doi = {10.1002/eji.201970300}, pages = {203 -- 204}, year = {2019}, language = {en} } @misc{Richly2019, author = {Richly, Keven}, title = {A survey on trajectory data management for hybrid transactional and analytical workloads}, series = {IEEE International Conference on Big Data (Big Data)}, journal = {IEEE International Conference on Big Data (Big Data)}, publisher = {IEEE}, address = {New York}, isbn = {978-1-5386-5035-6}, issn = {2639-1589}, doi = {10.1109/BigData.2018.8622394}, pages = {562 -- 569}, year = {2019}, abstract = {Rapid advances in location-acquisition technologies have led to large amounts of trajectory data. This data is the foundation for a broad spectrum of services driven and improved by trajectory data mining. However, for hybrid transactional and analytical workloads, the storing and processing of rapidly accumulated trajectory data is a non-trivial task. In this paper, we present a detailed survey about state-of-the-art trajectory data management systems. To determine the relevant aspects and requirements for such systems, we developed a trajectory data mining framework, which summarizes the different steps in the trajectory data mining process. Based on the derived requirements, we analyze different concepts to store, compress, index, and process spatio-temporal data. There are various trajectory management systems, which are optimized for scalability, data footprint reduction, elasticity, or query performance. To get a comprehensive overview, we describe and compare different exciting systems. Additionally, the observed similarities in the general structure of different systems are consolidated in a general blueprint of trajectory management systems.}, language = {en} } @misc{Richly2019, author = {Richly, Keven}, title = {Leveraging spatio-temporal soccer data to define a graphical query language for game recordings}, series = {IEEE International Conference on Big Data (Big Data)}, journal = {IEEE International Conference on Big Data (Big Data)}, publisher = {IEEE}, address = {New York}, isbn = {978-1-5386-5035-6}, issn = {2639-1589}, doi = {10.1109/BigData.2018.8622159}, pages = {3456 -- 3463}, year = {2019}, abstract = {For professional soccer clubs, performance and video analysis are an integral part of the preparation and post-processing of games. Coaches, scouts, and video analysts extract information about strengths and weaknesses of their team as well as opponents by manually analyzing video recordings of past games. Since video recordings are an unstructured data source, it is a complex and time-intensive task to find specific game situations and identify similar patterns. In this paper, we present a novel approach to detect patterns and situations (e.g., playmaking and ball passing of midfielders) based on trajectory data. The application uses the metaphor of a tactic board to offer a graphical query language. With this interactive tactic board, the user can model a game situation or mark a specific situation in the video recording for which all matching occurrences in various games are immediately displayed, and the user can directly jump to the corresponding game scene. Through the additional visualization of key performance indicators (e.g.,the physical load of the players), the user can get a better overall assessment of situations. With the capabilities to find specific game situations and complex patterns in video recordings, the interactive tactic board serves as a useful tool to improve the video analysis process of professional sports teams.}, language = {en} } @misc{RenzMeinel2019, author = {Renz, Jan and Meinel, Christoph}, title = {The "Bachelor Project"}, series = {2019 IEEE Global Engineering Education Conference (EDUCON)}, journal = {2019 IEEE Global Engineering Education Conference (EDUCON)}, publisher = {IEEE}, address = {New York}, isbn = {978-1-5386-9506-7}, issn = {2165-9567}, doi = {10.1109/EDUCON.2019.8725140}, pages = {580 -- 587}, year = {2019}, abstract = {One of the challenges of educating the next generation of computer scientists is to teach them to become team players, that are able to communicate and interact not only with different IT systems, but also with coworkers and customers with a non-it background.
