Visible light is becoming an important technology complementing existing Radio Frequency (RF) technologies such as Cellular V2X (C-V2X) and Dedicated Short Range Communication (DSRC). In this scope, first works helped introducing new simulation models to explore V-VLC capabilities, technologies, and algorithms. Yet, experimental prototypes are still in an early phase. We aim bridging this gap with our system, which integrates a custom-made driver hardware, commercial vehicle light modules, and an Open Source signal processing implementation in GNU Radio, which explicitly offers rapid prototyping. Our system supports OFDM with a variety of Modulation and Coding Schemes (MCS) and is compliant to IEEE 802.11; this is in line with the upcoming IEEE 802.11 LC standard as well. In an extensive series of experiments, we assessed the communication performance by looking at realistic inter vehicle distances. Our results clearly show that our system supports even higher order MCS with very low error rates over long distances.}}, author = {{Amjad, Muhammad Sohaib and Tebruegge, Claas and Memedi, Agon and Kruse, Stephan and Kress, Christian and Scheytt, Christoph and Dressler, Falko}}, booktitle = {{IEEE International Conference on Communications (ICC)}}, pages = {{1--6}}, publisher = {{ICC 2019 - 2019 IEEE International Conference on Communications (ICC)}}, title = {{{An IEEE 802.11 Compliant SDR-Based System for Vehicular Visible Light Communications}}}, doi = {{10.1109/ICC.2019.8761960}}, year = {{2019}}, } @article{34437, abstract = {{In oil-lubricated worm gears, all moving components cause power losses during operation. These losses depend, among other things, on the viscosity of the lubricant used, which in turn is determined by the temperature present in the gearbox. The dependency between the temperature and the power dissipation is mutual, and they influence each other. For the analysis of gearboxes under transient conditions, the relationship among operating conditions, power dissipation, and temperature must be considered. In this paper, a method for the analysis of these interrelationships is presented, which is based on the combination of tribological simulation and thermal networks. With the developed calculation model, the gearbox efficiency and the temperature over time can be estimated for arbitrary load cases. The calculation results are compared with measurements on a real gearbox.}}, author = {{Oehler, Manuel and Sauer, Bernd and Magyar, Balázs}}, issn = {{0742-4787}}, journal = {{Journal of Tribology}}, number = {{12}}, title = {{{Efficiency of Worm Gear Drives Under Transient Operating Conditions}}}, doi = {{10.1115/1.4044655}}, volume = {{141}}, year = {{2019}}, } @article{20282, abstract = {{Modern developments in the automotive sector are motivated by the objective of lowering the emission of pollutants. In contrast, growing demands for safety and comfort lead to a potential increase of the weight of vehicles. Thus, the consequent use of lightweight design is indispensable. This includes the use of different materials for the construction of car bodies. Because of various material properties, joining of dissimilar materials is challenging and requires often the application of non-thermic processes like riveting or clinching. These processes are limited by the mechanical properties of the joining partners. Especially the increasing use of ultra-high strength alloys, like the hot stamped steel 22MnB5, makes the development of new joining technologies necessary. One of these innovative technologies is shear-clinching. By combining shear-cutting and clinching in one process, this technology produces durable and tight connections of dissimilar materials with high differences regarding strength and formability. In contrast to shear-cutting the die-sided material has no contact with the punch. Since the process of shear-clinching is a combination of cutting and joining using the same tool, the tool loads differ from common shear-cutting. Especially cutting hot stamped steels is a challenge due to their high ultimate strength which leads to high tool loads. Thus, the analysis of the load condition is essential for the dimensioning of durable and wear resistant tools. Hence, the scope of this paper is a numerical investigation of the tool loads during the indirect cutting process and the subsequent step of joining by forming during shear-clinching. Since an experimental investigation of the occurring tool loads in the closed process is not practicable, the finite element method has to be used. Therefore, a damage-based numerical model is set up to enable the coupled simulation of the combined cutting and joining process and the resulting tool loads. This allows the analysis of the loads during the whole process, identifying the influences of materials and sheet thicknesses.}}, author = {{Wiesenmayer, Sebastian and Müller, Martin and Dornberger, Peter and Han, Daxin and Hörhold, Réjane and Meschut, Gerson and Merklein, Marion}}, issn = {{1662-9795}}, journal = {{Key Engineering Materials}}, pages = {{397--404}}, title = {{{Numerical Investigation of the Tool Load in Joining by Forming of Dissimilar Materials Using Shear-Clinching Technology}}}, doi = {{10.4028/www.scientific.net/kem.767.397}}, year = {{2018}}, } @article{27981, author = {{Weber, KS and Simon, MC and Strassburger, K and Markgraf, DF and Buyken, Anette and Szendroedi, J and Müssig, K and Roden, M and Group, GDS}}, issn = {{2072-6643}}, journal = {{Nutrients}}, number = {{6}}, title = {{{Habitual Fructose Intake Relates to Insulin Sensitivity and Fatty Liver Index in Recent-Onset Type 2 Diabetes Patients and Individuals without Diabetes.}}}, doi = {{10.3390/nu10060774}}, volume = {{10}}, year = {{2018}}, } @inproceedings{24196, abstract = {{This paper presents an approach for analog fault effect simulation automation based on random fault selection with a high fault coverage of the circuit under test by means of fault injection and simulation based on advanced sampling techniques.

In this study, simulations are performed to characterize the effect of domain size on pressure drop, residual saturation, liquid film thickness and interfacial area concentration, using virtual nonwoven and foam filters with similar micro-structural properties. Further, experiments using micro-CT are performed to validate the present computational simulations. It is found that two phase flow through filters are more sensitive to local geometric variations or mesh resolution in the porous media than single phase flow. Statistical uncertainties in the steady state quantities of less than +-10% can be expected to cope with the increase in computing power required for practical mesh sizes.

Therefore three types of couples with different labor force participations were formed: Dual-earner couples, couples with additional female income and malebreadwinner couples. The time use for the mentioned activities was examined with a secondary analysis based on the German representative time use surveys of 2012/2013 and 2001/2002. The analysis showed that fulltime mothers spent the lowest amount of time for caring, cooking and cleaning. However, unemployed mothers spent the most time for these activities. Within a decade – from 2001/2002 to 2012/2013 – all mothers have reduced their time spent on household activities. Meanwhile, all parents in 2012/2013 take noticeably more time for child care. Regardless of the mother’s labor force participation, mothers still spent more time for caring, cooking and cleaning, especially on weekdays. Additionally, the everyday housework is divided by gender. Only on weekends, couples with employed mothers shared the care-work almost egalitarian. Zusammenfassung Vor dem Hintergrund der steigenden Erwerbstätigkeit von Müttern geht dieser Beitrag der Frage nach, wie Eltern in Paarbeziehungen die Haushaltsbereiche Betreuung, Beköstigung sowie Wohnungs- und Wäschereinigung untereinander aufteilen. Dazu werden drei Paartypen mit unterschiedlichem Erwerbsumfang gebildet: Zweiverdiener- Paare, Paare mit weiblichem Zuverdienst sowie Paare mit männlichem Familienernährer. Deren Zeitverwendung für die genannten Tätigkeiten wird mithilfe der repräsentativen Zeitverwendungserhebung 2012/2013 und 2001/2002 sekundäranalytisch untersucht. Die Analyse zeigt, dass vollzeiterwerbstätige Mütter täglich am wenigsten Zeit für die drei genannten Arbeitsbereiche im Haushalt aufwenden, nicht erwerbstätige Mütter hingegen am meisten. Innerhalb einer Dekade – von 2001/2002 bis 2012/2013 – haben alle untersuchten Mütter ihre Zeitverwendung für hauswirtschaftliche Tätigkeitsfelder reduziert, zeitgleich nehmen sich Eltern 2012/2013 deutlich mehr Zeit für Betreuungsaufgaben. Unabhängig des Erwerbsumfangs der Mutter ist die Arbeit des Alltags nach wie vor, besonders werktags, weiblich konnotiert und somit geschlechtsdifferenzierend aufgeteilt. Nur am Wochenende zeigt sich in Paaren mit erwerbstätiger Mutter bei der Betreuung eine annährend egalitäre Arbeitsteilung.}}, author = {{Klünder, Nina and Meier-Gräwe, Uta}}, issn = {{2699-2337}}, journal = {{Journal of Family Research}}, pages = {{9--28}}, title = {{{Caring, Cooking, Cleaning – repräsentative Zeitverwendungsmuster von Eltern in Paarbeziehungen}}}, doi = {{10.3224/zff.v30i1.02}}, year = {{2018}}, } @article{26871, author = {{Klünder, Nina}}, journal = {{Hauswirtschaft und Wissenschaft }}, pages = {{1--24}}, title = {{{Zwischen selbst Gekochtem, Thermomix und Schulverpflegung – Innenansichten der Ernährungsversorgung von Familien mit erwerbstätigen Eltern}}}, doi = {{10.23782/HUW_21_2018}}, volume = {{66}}, year = {{2018}}, } @article{26890, author = {{Buyken, Anette and Cheng, Guo and Günther, Anke LB and Liese, Angela D and Remer, Thomas and Karaolis-Danckert, Nadina}}, issn = {{0002-9165}}, journal = {{The American Journal of Clinical Nutrition}}, pages = {{755--762}}, title = {{{Relation of dietary glycemic index, glycemic load, added sugar intake, or fiber intake to the development of body composition between ages 2 and 7 y}}}, doi = {{10.1093/ajcn/88.3.755}}, year = {{2018}}, } @article{26928, author = {{Penczynski, Katharina J. and Herder, Christian and Krupp, Danika and Rienks, Johanna and Egert, Sarah and Wudy, Stefan A. and Roden, Michael and Remer, Thomas and Buyken, Anette}}, issn = {{1436-6207}}, journal = {{European Journal of Nutrition}}, pages = {{1159--1172}}, title = {{{Flavonoid intake from fruit and vegetables during adolescence is prospectively associated with a favourable risk factor profile for type 2 diabetes in early adulthood}}}, doi = {{10.1007/s00394-018-1631-3}}, year = {{2018}}, } @inproceedings{26962, author = {{Schöppner, Volker and Sporkmann, F.}}, booktitle = {{34th International Conference of the Polymer Processing Society (PPS)}}, location = {{Taipei (Taiwan)}}, title = {{{New Method to Analyze the Throughput-Pressure Behavior with the Corrected Twin Screw Channel Geometry and the Induced Drag Flow of Screw Elements by Using 3D FEM Simulation}}}, year = {{2018}}, } @inproceedings{26963, author = {{Moritzer, Elmar and Heiderich, G. and Wittke, M.}}, booktitle = {{34th International Conference of the Polymer Processing Society (PPS)}}, location = {{Taipei (Taiwan)}}, title = {{{Numerical Simulation of Residence Time, Shear Rates and Throughput in Single Screw Extruders Considering Wall Shear Rates}}}, year = {{2018}}, } @inproceedings{3588, abstract = {{In scientific computing, unstructured meshes are a crucial foundation for the simulation of real-world physical phenomena.

There exists a wealth of supporting libraries and frameworks that aid programmers with the implementation of applications working on such grids, each built on top of existing parallelization technologies. However, many approaches require the programmer to introduce a different programming paradigm into their application or provide different variants of the code. SYCL is a new programming standard providing a remedy to this dilemma by building on standard C ++17 with its so-called single-source approach: Programmers write standard C ++ code and expose parallelism using C++17 keywords. The application is
then transformed into a concrete implementation by the SYCL implementation. By encapsulating the OpenCL ecosystem, different SYCL implementations enable not only the programming of CPUs but also of heterogeneous platforms such as GPUs or other devices. For the first time, this paper showcases a SYCL-
based solver for the nodal Discontinuous Galerkin method for Maxwell’s equations on unstructured meshes. We compare our solution to a previous C-based implementation with respect to programmability and performance on heterogeneous platforms.
