It was fabricated in a 130 nm SiGe process featuring an ft and fmax of 240 and 330 GHz. The on-chip system contains a 120 GHz VCO with a tuning range of 7 GHz featuring a divide-by-64 circuit to enable external PLL operation. The subsequent buffer provides 7 dBm of output power at 120 GHz. Additionally, the IC contains high-precision and high-resolution phase shifters based on a slow-wave transmission line approach with digital control for direct readout ability. A 120 GHz LNA with 17 dB gain and a power detector to provide DC output signals were realized on chip. It enables sample emulation capability by phase shift inducement in the measurement as well as a reference transmission line. In terms of phase detection, the system shows a sensitivity of 907.36 MHz/°.}}, author = {{Wessel, Jan and Schmalz, Klaus and Scheytt, Christoph and Kissinger, Dietmar}}, issn = {{1558-1764}}, journal = {{IEEE Microwave and Wireless Components Letters}}, number = {{2}}, pages = {{198--200}}, title = {{{A 120-GHz Electrical Interferometer for Contactless Permittivity Measurements With Direct Digital Read-Out}}}, doi = {{10.1109/LMWC.2017.2649384}}, volume = {{27}}, year = {{2017}}, } @article{24378, author = {{Krebs, Benjamin and Wehner, Marius and Kabst, Rüdiger}}, journal = {{Personalmagazin}}, pages = {{20--23}}, title = {{{Wer hat hier das Sagen?}}}, volume = {{2}}, year = {{2017}}, } @article{24379, author = {{Krebs, Benjamin and Wehner, Marius and Kabst, Rüdiger}}, journal = {{Personalmagazin}}, pages = {{24--25}}, title = {{{Nordeuropa hat´s nicht nötig}}}, volume = {{2}}, year = {{2017}}, } @article{24380, author = {{Rauterberg, Hannah and Krebs, Benjamin}}, journal = {{Personalführung}}, pages = {{28--33}}, title = {{{Cranet Survey 2015/2016 - Stand der HR-Digitalisierung.}}}, volume = {{5}}, year = {{2017}}, } @inproceedings{24398, abstract = {{Through this study, we introduce the idea of applying scheduling techniques to allocate spatial resources that are shared among multiple robots moving in a static environment and having temporal constraints on the arrival time to destinations. To illustrate this idea, we present an exemplified algorithm that plans and assigns a motion path to each robot. The considered problem is particularly challenging because: (i) the robots share the same environment and thus the planner must take into account overlapping paths which cannot happen at the same time; (ii) there are time deadlines thus the planner must deal with temporal constraints; (iii) new requests arrive without a priori knowledge thus the planner must be able to add new paths online and adjust old plans; (iv) the robot motion is subject to noise thus the planner must be reactive to adapt to online changes. We showcase the functioning of the proposed algorithm through a set of agent-based simulations.}}, author = {{Khaluf, Yara and Markarian, Christine and Simoens, Pieter and Reina, Andreagiovanni}}, booktitle = {{International Conference on Practical Applications of Agents and Multi-Agent Systems (PAAMS 2017)}}, issn = {{0302-9743}}, title = {{{Scheduling Access to Shared Space in Multi-robot Systems}}}, doi = {{10.1007/978-3-319-59930-4_12}}, year = {{2017}}, } @article{24523, author = {{Moritzer, Elmar and Hopp, Matthias}}, issn = {{0043-2288}}, journal = {{Welding in the World}}, pages = {{1029--1038}}, title = {{{Bonding of wood-plastic composites (WPC)—material and surface modification for special applications}}}, doi = {{10.1007/s40194-017-0487-0}}, year = {{2017}}, } @inproceedings{24529, author = {{Moritzer, Elmar and Hopp, Matthias}}, booktitle = {{75th Annual Technical Conference of the Society of Plastics Engineers (ANTEC)}}, title = {{{Bonding of Plastic Parts with Dispersion Adhesives – Film Formation via Diffusion Processes}}}, year = {{2017}}, } @article{24636, author = {{Philipp, Matthias and Schumm, Gregor and Peesel, Ron-Hendrik and Walmsley, Timothy G. and Atkins, Martin J. and Schlosser, Florian and Hesselbach, Jens}}, issn = {{0360-5442}}, journal = {{Energy}}, pages = {{112--123}}, title = {{{Optimal energy supply structures for industrial food processing sites in different countries considering energy transitions}}}, doi = {{10.1016/j.energy.2017.05.062}}, year = {{2017}}, } @article{24637, author = {{Schumm, G. and Philipp, M. and Schlosser, Florian and Hesselbach, J. and Walmsley, T.

Combining all-atom molecular dynamics and capillary simulations we demonstrate that the linear scaling of the interparticle forces with the particle diameter, well established for microscopic and macroscopic particles, can be extended down to diameters of a few nm. At this size scale, however, the molecular nature of the water adsorbates dictates the adhesion forces both via solvation effects and influencing parameters of analytical capillary models such as the equilibrium particle–particle separation distance and the water/particle contact angle. Moreover, the water surface tension becomes considerably larger than the macroscopic bulk value due to combined effects of thin-film confinement and tight curvature, in a way that strongly depends on humidity and particle size. Taking these effects into proper account, classical capillary equations can be used to predict the interparticle forces even of the smallest particles considered here (4 nm), although the circular approximation fails to reproduce the distance at which the water meniscus breaks. Finally, the transition between the dominating effects at the nanoscopic scale and conventional capillary theory valid at microscopic size scales can be only rationalized if the presence of roughness asperities on the surface of the large particles is explicitly taken into account.}}, author = {{Laube, Jens and Dörmann, Michael and Schmid, Hans-Joachim and Mädler, Lutz and Colombi Ciacchi, Lucio}}, issn = {{1932-7447}}, journal = {{The Journal of Physical Chemistry C}}, pages = {{15294--15303}}, title = {{{Dependencies of the Adhesion Forces between TiO2 Nanoparticles on Size and Ambient Humidity}}}, doi = {{10.1021/acs.jpcc.7b05655}}, year = {{2017}}, } @article{26107, abstract = {{Capillary forces are very important considering the handling of powders as they, in general, exceed other adhesion forces. These capillary forces are dependent on several different parameters. Especially the distance between the particles is an important parameter. For example, in moving bulk solids a large variety of distances between particles will occur. Therefore, the distance-dependence of capillary bridges was investigated with a numerical simulation method, assuming thermodynamic equilibrium which is attained very fast for small particles. This method uses the Kelvin equation and the Young-Laplace equation to calculate numerically the shape of the capillary bridge without any assumption regarding the shape. The force is eventually derived from the meniscus shape. The distance becomes extremely important when the capillary liquid bridge between two surfaces is only determined by capillary condensation depending on relative humidity. Only a slight increase of the distance within the fraction of a nanometer changes the behaviour of the capillary force significantly. Furthermore, the influence of the force on the separation of particles will be presented. The force decreases almost linearly with increasing distance for a wide range of distances and consequently, a contact stiffness for capillary bridges could be derived. These results may e.g. be used in DEM models. Also, the maximum separation distance of capillary bridges in thermodynamic equilibrium and the correlation with the according bridge volume was investigated. As two limiting cases for capillary bridges at varying distances one can assume either a constant curvature, i.e. infinitely fast attainment of equilibrium, or a constant volume, i.e. infinitely slow attainment of equilibrium. Therefore, a comparison of these two possibilities will be presented and discussed as well.}}, author = {{Dörmann, Michael and Schmid, Hans-Joachim}}, issn = {{0032-5910}}, journal = {{Powder Technology}}, pages = {{175--183}}, title = {{{Distance-dependency of capillary bridges in thermodynamic equilibrium}}}, doi = {{10.1016/j.powtec.2017.01.012}}, year = {{2017}}, }
