The model proposed approximates the behavior of the nonlinear scattering (S)-parameters and noise figure of each building block of the TRX chipset by Laplace polynomials and hyperbolic tangent functions. The modular approach of the model allows to optimize hardware components with respect to the entire TRX system, and fault identification with reduced computational effort. The proposed method is validated using the first monolithically integrated photonic radar transceiver chipset and shows excellent agreement with the post layout simulation results and, including the photodiode (PD) bandwidth (BW) degradation, also with the measurements. }}, author = {{Kruse, Stephan and Schwabe, Tobias and Kneuper, Pascal and Meinecke, Marc-Michael and Kurz, Heiko G. and Scheytt, J.

Popular applications are image denoising, sparse regression and machine learning. Since the choice of the regularization parameter is crucial but often difficult, path-following methods are used to approximate the entire regularization path, i.e., the set of all possible solutions for all regularization parameters. Due to their nature, the development of these methods requires structural results about the regularization path. The goal of this article is to derive these results for the case of a smooth objective function which is penalized by a piecewise differentiable regularization term. We do this by treating regularization as a multiobjective optimization problem. Our results suggest that even in this general case, the regularization path is piecewise smooth. Moreover, our theory allows for a classification of the nonsmooth features that occur in between smooth parts. This is demonstrated in two applications, namely support-vector machines and exact penalty methods.}}, author = {{Gebken, Bennet and Bieker, Katharina and Peitz, Sebastian}}, journal = {{Journal of Global Optimization}}, number = {{3}}, pages = {{709--741}}, title = {{{On the structure of regularization paths for piecewise differentiable regularization terms}}}, doi = {{10.1007/s10898-022-01223-2}}, volume = {{85}}, year = {{2023}}, } @article{42966, author = {{Sherman, David A. and Baumeister, Jochen and Stock, Matt S. and Murray, Amanda M. and Bazett-Jones, David M. and Norte, Grant E.}}, issn = {{1530-0315}}, journal = {{Medicine & Science in Sports & Exercise}}, keywords = {{Physical Therapy, Sports Therapy and Rehabilitation, Orthopedics and Sports Medicine}}, publisher = {{Ovid Technologies (Wolters Kluwer Health)}}, title = {{{Weaker Quadriceps Corticomuscular Coherence in Individuals Following ACL Reconstruction during Force Tracing}}}, doi = {{10.1249/mss.0000000000003080}}, volume = {{Publish Ahead of Print}}, year = {{2023}}, } @article{42967, author = {{Büchel, Daniel and Torvik, PØ and Lehmann, Tim and Sandbakk, Ø and Baumeister, Jochen}}, issn = {{0195-9131}}, journal = {{Med Sci Sports Exerc}}, title = {{{The Mode of Endurance Exercise Influences Changes in EEG Resting State Graphs among High-Level Cross-Country Skiers.}}}, year = {{2023}}, } @article{42965, author = {{Sherman, DA and Baumeister, Jochen and Stock, MS and Murray, AM and Bazett-Jones, DM and Norte, GE}}, issn = {{0195-9131}}, journal = {{Med Sci Sports Exerc}}, number = {{3}}, pages = {{440--449}}, title = {{{Inhibition of Motor Planning and Response Selection after Anterior Cruciate Ligament Reconstruction.}}}, volume = {{55}}, year = {{2023}}, } @article{43018, author = {{Alhaddad, Samer and Förstner, Jens and Grynko, Yevgen}}, issn = {{0022-4073}}, journal = {{Journal of Quantitative Spectroscopy and Radiative Transfer}}, keywords = {{tet_topic_scattering}}, publisher = {{Elsevier BV}}, title = {{{Numerical study of light backscattering from layers of absorbing irregular particles larger than the wavelength}}}, doi = {{10.1016/j.jqsrt.2023.108557}}, volume = {{302}}, year = {{2023}}, } @inproceedings{39359, author = {{Mwammenywa, Ibrahim and Petrov, Dmitry and Holle, Philipp and Hilleringmann, Ulrich}}, booktitle = {{2022 International Conference on Engineering and Emerging Technologies (ICEET)}}, publisher = {{IEEE}}, title = {{{LoRa Transceiver for Load Monitoring and Control System in Microgrids}}}, doi = {{10.1109/iceet56468.2022.10007274}}, year = {{2023}}, } @inbook{38150, author = {{Fuchs, Christian}}, booktitle = {{Adorno und die Medien: Kritik, Relevanz, Ethik}}, editor = {{ Popp, Judith-Frederike and Voropai, Lioudmila}}, pages = {{215--236}}, publisher = {{Kulturverlag Kadmos}}, title = {{{Adorno and the Media in Digital Capitalism}}}, year = {{2023}}, } @unpublished{43048, author = {{Lienen, Christian and Middeke, Sorel Horst and Platzner, Marco}}, title = {{{fpgaDDS: An Intra-FPGA Data Distribution Service for ROS 2 Robotics Applications}}}, year = {{2023}}, } @article{43054, abstract = {{Artificial intelligence (AI) has moved beyond the planning phase in many organisations and it is often accompanied by uncertainties and fears of job loss among employees.

In this respect, this paper reports the characterization of a unidirectional carbon fiber reinforced polymer composite material. Particularly, the mechanical behavior of the overall composite and of the individual constituents of the composite is investigated. To this end, tensile and shear tests are performed for the composite. As a result, statistics for five transversely isotropic material parameters can be established for the composite. For the description of the mechanical properties of the constituents, tensile tests for the carbon fiber as well as for the polymer matrix are carried out. In addition, the volume fraction of fibers in the matrix is determined experimentally using an ashing technique and Archimedes’ principle. For the Young’s modulus of the fiber, the Young’s modulus and transverse contraction of the matrix, as well as the volume fraction of the constituents, statistics can be concluded. The resulting mechanical properties on both scales are useful for the application and validation of different material models and homogenization methods. Finally, in order to validate the obtained properties in the future, inhomogeneous tests were performed, once a flat plate with a hole and a flat plate with semicircular notches.}}, author = {{Penner, Eduard and Caylak, Ismail and Mahnken, Rolf}}, issn = {{1229-9197}}, journal = {{Fibers and Polymers}}, keywords = {{Polymers and Plastics, General Chemical Engineering, General Chemistry}}, publisher = {{Springer Science and Business Media LLC}}, title = {{{Experimental Investigations of Carbon Fiber Reinforced Polymer Composites and Their Constituents to Determine Their Elastic Material Properties and Complementary Inhomogeneous Experiments with Local Strain Considerations}}}, doi = {{10.1007/s12221-023-00122-x}}, year = {{2023}}, } @article{43095, author = {{Lenz, Peter and Mahnken, Rolf}}, issn = {{0263-8223}}, journal = {{Composite Structures}}, keywords = {{Civil and Structural Engineering, Ceramics and Composites}}, publisher = {{Elsevier BV}}, title = {{{Non-local integral-type damage combined to mean-field homogenization methods for composites and its parallel implementation}}}, doi = {{10.1016/j.compstruct.2023.116911}}, year = {{2023}}, } @inproceedings{31849, author = {{Hoffmann, Max and Biehler, Rolf}}, booktitle = {{Proceedings of the Fourth Conference of the International Network for Didactic Research in University Mathematics (INDRUM 2022, 19-22 October 2022)}}, editor = {{Trigueros, Marı́a and Barquero, Berta and Hochmuth, Reinhard and Peters, Jana}}, keywords = {{Teaching and learning of specific topics in university mathematics, Transition to, across and from university mathematics, Student Teachers, Geometry, Congruence, Double Discontinuity.}}, publisher = {{University of Hannover and INDRUM.}}, title = {{{Student Teachers ’ Knowledge of Congruence before a University Course on Geometry}}}, year = {{2023}}, }
