@article{30904, abstract = {{The process chain for the manufacturing of sheet metal components in mass production includes various cutting and forming operations, which influence the resulting properties of the parts and therefore subsequent manufacturing steps, such as clamping and joining. It is shown that clamping of the components leads to superimposed residual stresses and geometry changes. Therefore, the part properties differ from the initial state of the semifinished products, which has to be considered in the design of clinched joints. This paper presents an approach for coupled determination of the properties of semifinished and finished parts during deep drawing and clamping as well as their effects on the joint quality during clinching. One method for the effective and efficient determination of the properties of semifinished products and components during production is using process data from the preceding manufacturing processes, which is concretely presented in this work. In addition to the interconnection of the entire production chain, it is necessary to define relevant process data for each individual manufacturing step and to correlate the data with the material properties reliably. Therefore, the cross-process interactions of different steps of the process chain for the manufacturing of sheet metal components and the effect of process variations on subsequent manufacturing steps are investigated. Consequently, the boundary conditions for a mechanical joining process based on data from preceding process steps can be predicted.}}, author = {{Heyser, Per and Wiesenmayer, S and Frey, P and Nehls, T and Scharr, C and Flügge, W and Merklein, M and Meschut, Gerson}}, issn = {{1464-4207}}, journal = {{Proceedings of the Institution of Mechanical Engineers, Part L: Journal of Materials: Design and Applications}}, keywords = {{Mechanical Engineering, General Materials Science}}, publisher = {{SAGE Publications}}, title = {{{Consideration of the manufacturing history of sheet metal components for the adaptation of a clinching process}}}, doi = {{10.1177/14644207221077560}}, year = {{2022}}, } @inbook{29928, author = {{Yigitbas, Enes and Sauer, Stefan and Engels, Gregor}}, booktitle = {{Digital Transformation: Core Technologies and Emerging Topics from a Computer Science Perspective}}, editor = {{Vogel-Heuser, Birgit and Wimmer, Manuel}}, publisher = {{Springer-Vieweg}}, title = {{{Self-Adaptive Digital Assistance Systems for Work 4.0}}}, year = {{2022}}, } @article{30964, author = {{Gao, Wenlong and Sain, Basudeb and Zentgraf, Thomas}}, issn = {{2331-7019}}, journal = {{Physical Review Applied}}, keywords = {{General Physics and Astronomy}}, number = {{4}}, publisher = {{American Physical Society (APS)}}, title = {{{Spin-Orbit Interaction of Light Enabled by Negative Coupling in High-Quality-Factor Optical Metasurfaces}}}, doi = {{10.1103/physrevapplied.17.044022}}, volume = {{17}}, year = {{2022}}, } @article{23398, abstract = {{We study output reference tracking of systems with high relative degree via output feedback only; this is, tracking where the output derivatives are unknown.

Trusted execution environments, such as Intel SGX enclaves, promise to provide a secure environment in which data can be decrypted and then processed. However, vulnerabilities in the executed program give attackers ample opportunities to execute arbitrary code inside the enclave. This code can modify the dataflow of the program and leak secrets via SGX side channels. Fully homomorphic encryption would be an alternative to compute on encrypted data without data leaks. However, due to its high computational complexity, its applicability to general-purpose computing remains limited. Researchers have made several proposals for transforming programs to perform encrypted computations on less powerful encryption schemes. Yet current approaches do not support programs making control-flow decisions based on encrypted data. We introduce the concept of dataflow authentication (DFAuth) to enable such programs. DFAuth prevents an adversary from arbitrarily deviating from the dataflow of a program. Our technique hence offers protections against the side-channel attacks described previously. We implemented two flavors of DFAuth, a Java bytecode-to-bytecode compiler, and an SGX enclave running a small and program-independent trusted code base. We applied DFAuth to a neural network performing machine learning on sensitive medical data and a smart charging scheduler for electric vehicles. Our transformation yields a neural network with encrypted weights, which can be evaluated on encrypted inputs in \( 12.55 \,\mathrm{m}\mathrm{s} \) . Our protected scheduler is capable of updating the encrypted charging plan in approximately 1.06 seconds. }}, author = {{Fischer, Andreas and Fuhry, Benny and Kußmaul, Jörn and Janneck, Jonas and Kerschbaum, Florian and Bodden, Eric}}, issn = {{2471-2566}}, journal = {{ACM Transactions on Privacy and Security}}, keywords = {{Safety, Risk, Reliability and Quality, General Computer Science}}, number = {{3}}, pages = {{1--36}}, publisher = {{Association for Computing Machinery (ACM)}}, title = {{{Computation on Encrypted Data Using Dataflow Authentication}}}, doi = {{10.1145/3513005}}, volume = {{25}}, year = {{2022}}, } @article{31327, author = {{Stöckmann, Nico}}, issn = {{2162-2078}}, journal = {{Theoretical Economics Letters}}, number = {{01}}, pages = {{98--110}}, publisher = {{Scientific Research Publishing, Inc.}}, title = {{{Conditional Beta-Convergence by Gravity}}}, doi = {{10.4236/tel.2022.121006}}, volume = {{12}}, year = {{2022}}, } @misc{31947, author = {{Hillebrandt, Henning}}, title = {{{Verteiltes Berechnen kompakter Routingtabellen in Unit Disk Graphen}}}, year = {{2022}}, } @article{30966, author = {{Ren, Jiahuan and Liao, Qing and Ma, Xuekai and Schumacher, Stefan and Yao, Jiannian and Fu, Hongbing}}, issn = {{1863-8880}}, journal = {{Laser & Photonics Reviews}}, number = {{1}}, publisher = {{Wiley}}, title = {{{Realization of Exciton‐Mediated Optical Spin‐Orbit Interaction in Organic Microcrystalline Resonators}}}, doi = {{10.1002/lpor.202100252}}, volume = {{16}}, year = {{2022}}, } @article{30967, author = {{Zhang, Xiu and Chen, Zhenshi and Liu, Dong and Wan, Lei and Ma, Xuekai and Gao, Tingge}}, issn = {{1882-0778}}, journal = {{Applied Physics Express}}, number = {{2}}, publisher = {{IOP Publishing}}, title = {{{Controlling exciton distribution in WS2 monolayer on a photonic crystal}}}, doi = {{10.35848/1882-0786/ac48d8}}, volume = {{15}}, year = {{2022}}, } @article{31938, author = {{Wingenbach, Jan and Pukrop, Matthias and Schumacher, Stefan and Ma, Xuekai}}, journal = {{Physical Review B}}, number = {{24}}, publisher = {{APS}}, title = {{{Dynamics of phase defects trapped in optically imprinted orbits in dissipative binary polariton condensates}}}, doi = {{10.1103/PhysRevB.105.245302}}, volume = {{105}}, year = {{2022}}, } @article{31982, abstract = {{AbstractWe show that for a generic conformal metric perturbation of a compact hyperbolic 3-manifold $$\Sigma $$ Σ with Betti number $$b_1$$ b 1 , the order of vanishing of the Ruelle zeta function at zero equals $$4-b_1$$ 4 - b 1 , while in the hyperbolic case it is equal to $$4-2b_1$$ 4 - 2 b 1 .

The proof uses the microlocal approach to dynamical zeta functions, giving a geometric description of generalized Pollicott–Ruelle resonant differential forms at 0 in the hyperbolic case and using first variation for the perturbation.
