--- _id: '10595' abstract: - lang: eng text: In this article we show that the boundary of the Pareto critical set of an unconstrained multiobjective optimization problem (MOP) consists of Pareto critical points of subproblems where only a subset of the set of objective functions is taken into account. If the Pareto critical set is completely described by its boundary (e.g., if we have more objective functions than dimensions in decision space), then this can be used to efficiently solve the MOP by solving a number of MOPs with fewer objective functions. If this is not the case, the results can still give insight into the structure of the Pareto critical set. article_type: original author: - first_name: Bennet full_name: Gebken, Bennet id: '32643' last_name: Gebken - first_name: Sebastian full_name: Peitz, Sebastian id: '47427' last_name: Peitz orcid: https://orcid.org/0000-0002-3389-793X - first_name: Michael full_name: Dellnitz, Michael last_name: Dellnitz citation: ama: Gebken B, Peitz S, Dellnitz M.

This refers to shorter settling times, lower overshoots, and a better decoupling of control variables in case of multi-variable controls. However, this can only be achieved if the used prediction model covers the actual behavior of the plant sufficiently well. In case of model deviations, the performance utilizing MPC remains below its potential. This results in effects like increased current ripple or steady state setpoint deviations. In order to achieve a high control performance, it is therefore necessary to adapt the model to the real plant behavior. When using an online system identification, a less accurate model is sufficient for commissioning of the drive system. In this paper, the combination of a finite-control-set MPC (FCS-MPC) with a system identification is proposed. The method does not require high-frequency signal injection, but uses the measured values already required for the FCS-MPC. An evaluation of the least squares-based identification on a laboratory test bench showed that the model accuracy and thus the control performance could be improved by an online update of the prediction models. author: - first_name: Soren full_name: Hanke, Soren last_name: Hanke - first_name: Sebastian full_name: Peitz, Sebastian id: '47427' last_name: Peitz orcid: https://orcid.org/0000-0002-3389-793X - first_name: Oliver full_name: Wallscheid, Oliver last_name: Wallscheid - first_name: Joachim full_name: Böcker, Joachim last_name: Böcker - first_name: Michael full_name: Dellnitz, Michael last_name: Dellnitz citation: ama: 'Hanke S, Peitz S, Wallscheid O, Böcker J, Dellnitz M.

With the goal set on an autonomous multi-movement prosthesis capable of performing training and classification of an amputee’s EMG signals, the focus of this paper lies in the acceleration of the embedded signal processing chain. We present two Xilinx Zynq-based architectures for accelerating two inherently different high density EMG-based control algorithms. The first hardware accelerated design achieves speed-ups of up to 4.8 over the software-only solution, allowing for a processing delay lower than the sample period of 1 ms. The second system achieved a speed-up of 5.5 over the software-only version and operates at a still satisfactory low processing delay of up to 15 ms while providing a higher reliability and robustness against electrode shift and noisy channels. author: - first_name: Alexander full_name: Boschmann, Alexander last_name: Boschmann - first_name: Andreas full_name: Agne, Andreas last_name: Agne - first_name: Georg full_name: Thombansen, Georg last_name: Thombansen - first_name: Linus Matthias full_name: Witschen, Linus Matthias id: '49051' last_name: Witschen - first_name: Florian full_name: Kraus, Florian last_name: Kraus - first_name: Marco full_name: Platzner, Marco id: '398' last_name: Platzner citation: ama: Boschmann A, Agne A, Thombansen G, Witschen LM, Kraus F, Platzner M.

However, single layer metasurface systems consisting of two-dimensional nanoparticle arrays exhibit only a weak spatial asymmetry perpendicular to the surface and therefore have mostly symmetric transmission features. Here, we present a metasurface design principle for nonreciprocal polarization encryption of holographic images. Our approach is based on a two-layer plasmonic metasurface design that introduces a local asymmetry and generates a bidirectional functionality with full phase and amplitude control of the transmitted light. The encoded hologram is designed to appear in a particular linear cross-polarization channel, while it is disappearing in the reverse propagation direction. Hence, layered metasurface systems can feature asymmetric transmission with full phase and amplitude control and therefore expand the design freedom in nanoscale optical devices toward asymmetric information processing and security features for anticounterfeiting applications. article_type: original author: - first_name: Daniel full_name: Frese, Daniel last_name: Frese - first_name: Qunshuo full_name: Wei, Qunshuo last_name: Wei - first_name: Yongtian full_name: Wang, Yongtian last_name: Wang - first_name: Lingling full_name: Huang, Lingling last_name: Huang - first_name: Thomas full_name: Zentgraf, Thomas id: '30525' last_name: Zentgraf orcid: 0000-0002-8662-1101 citation: ama: Frese D, Wei Q, Wang Y, Huang L, Zentgraf T.
