Eigenmodes of the constituting dielectric channels are computed numerically. The frequency-domain coupled-mode models then combine these into fully vectorial approximations for the optical electromagnetic fields of the composite structure. Following a discretization of amplitude functions by 1D finite elements, pro- cedures from the realm of finite-element numerics are applied to establish systems of linear equations for the then- discrete modal amplitudes. Examples substantiate the functioning of the technique and allow for some numerical assessment. The full 3D simulations are highly efficient in memory consumption, moderately demanding in com- putational time, and, in regimes of low radiative losses, sufficiently accurate for practical design. Our results include the perturbation of guided modes by changes of the refractive indices, the interaction of waves in parallel, horizontally or vertically coupled straight waveguides, and a series of crossings of potentially overlapping channels with fairly arbitrary relative positions and orientations.}}, author = {{Hammer, Manfred and Alhaddad, Samer and Förstner, Jens}}, issn = {{0740-3224}}, journal = {{Journal of the Optical Society of America B}}, keywords = {{tet_topic_waveguide, tet_topic_numerics}}, number = {{3}}, pages = {{613--624}}, publisher = {{The Optical Society}}, title = {{{Hybrid coupled-mode modeling in 3D: perturbed and coupled channels, and waveguide crossings}}}, doi = {{10.1364/josab.34.000613}}, volume = {{34}}, year = {{2017}}, } @inbook{3836, abstract = {{We apply the Discontinuous Galerkin Time Domain (DGTD) method for numerical simulations of the second harmonic generation from various metallic nanostructures.

Besides exploring the static shape of the examined system, observing the machines' mechanics (e.g., motor-driven mechanisms) and transport routes for the material transport (e.g., via conveyor belts or chains, or rail-based transport systems) can play an equally important role in such a review. In practice it is often the case, that the relevant information about transport routes, or kinematic properties is either not consequently modeled in the CAD data or is lost during conversion processes. To significantly reduce the manual effort and costs for creating animations of the machines complex behavior with such limited input data for a design review, we present a set of algorithms to automatically determine geometrical properties of machine parts based only on their triangulated surfaces. The algorithms allow to detect the course of transport systems, the orientation of objects in 3d space, rotation axes of cylindrical objects and holes, the number of tooth of gears, as well as the tooth spacing of toothed racks. We implemented the algorithms in the VR system PADrend and applied them to animate virtual prototypes of real machines.}}, author = {{Brandt, Sascha and Jähn, Claudius and Fischer, Matthias and Gerges, Maria and Berssenbrügge, Jan}}, booktitle = {{Proceedings of the ASME 2017 International Design Engineering Technical Conferences & Computers and Information in Engineering Conference, Band 1}}, pages = {{91:1--91:10}}, publisher = {{ASME}}, title = {{{Automatic Derivation of Geometric Properties of Components from 3D Polygon Models}}}, doi = {{https://doi.org/10.1115/DETC2017-67528}}, volume = {{1}}, year = {{2017}}, } @article{27414, author = {{Abdelgawad, Kareem and Gausemeier, Jürgen and Grafe, Michael and Berssenbrügge, Jan}}, journal = {{Designs ‒ International Journal of Engineering Designs, Band 1}}, pages = {{3.1--3.11}}, publisher = {{MDPI AG}}, title = {{{Interest Manager for Networked Driving Simulation Based on High-Level Architecture}}}, volume = {{1}}, year = {{2017}}, } @article{27513, author = {{Raacke, Georg}}, issn = {{2193-8806}}, journal = {{Haushalt in Bildung & Forschung}}, pages = {{69--80}}, title = {{{„Wer früher stirbt, ist selbst schuld!“ – Ein kritischer Blick auf das aktuelle Gesundheitsregime}}}, doi = {{10.3224/hibifo.v3i4.17334}}, year = {{2017}}, } @article{27522, author = {{Föcker, Manuel and Antel, Jochen and Ring, Stefanie and Hahn, Denise and Kanal, Özlem and Öztürk, Dana and Hebebrand, Johannes and Libuda, Lars}}, issn = {{1018-8827}}, journal = {{European Child & Adolescent Psychiatry}}, pages = {{1043--1066}}, title = {{{Vitamin D and mental health in children and adolescents}}}, doi = {{10.1007/s00787-017-0949-3}}, year = {{2017}}, } @article{27739, author = {{Cheng, Guo and Xue, Hongmei and Luo, Jiao and Jia, Hong and Zhang, Lishi and Dai, Junbiao and Buyken, Anette}}, issn = {{2045-2322}}, journal = {{Scientific Reports}}, title = {{{Relevance of the dietary glycemic index, glycemic load and genetic predisposition for the glucose homeostasis of Chinese adults without diabetes}}}, doi = {{10.1038/s41598-017-00453-9}}, year = {{2017}}, } @article{27745, author = {{Roßbach, Sarah and Diederichs, Tanja and Nöthlings, Ute and Buyken, Anette and Alexy, Ute}}, issn = {{0742-0528}}, journal = {{Chronobiology International}}, pages = {{336--347}}, title = {{{Relevance of chronotype for eating patterns in adolescents}}}, doi = {{10.1080/07420528.2017.1406493}}, year = {{2017}}, } @article{27754, author = {{Harris, Carla and Buyken, Anette and Koletzko, Sibylle and von Berg, Andrea and Berdel, Dietrich and Schikowski, Tamara and Koletzko, Berthold and Heinrich, Joachim and Standl, Marie}}, issn = {{2072-6643}}, journal = {{Nutrients}}, title = {{{Dietary Fatty Acids and Changes in Blood Lipids during Adolescence: The Role of Substituting Nutrient Intakes}}}, doi = {{10.3390/nu9020127}}, year = {{2017}}, }
