Laser Powder Bed Fusion (LPBF) is an AM technique that offers the possibility to manufacture metal parts in a more material efficient way due to the layer-by-layer build-up. Nevertheless, the processing chain for parts from LPBF contains additional steps like powder atomization, which also influence the ecological footprint of the production chain. Within this work, a life-cycle model for the production step of parts from AlSi10Mg powder material is developed. The model is supplied with data from the powder atomization up to the production step, either by literature, database or experimental measurements during production. The footprint in terms of CO2 emissions is then analyzed and emission-intense steps are identified. Two manufacturing scenarios are considered to evaluate the sensitivity on the emissions.}}, author = {{Bödger, Christian and Weiss, Christian and Schiefer, Ekkehard and Heussen, Daniel and Haefner, Constantin}}, booktitle = {{Proceedings of the 33rd Annual International Solid Freeform Fabrication Symposium – An Additive Manufacturing Conference}}, location = {{Austin}}, title = {{{Evaluation of the Ecological Footprint for Parts from AlSi10Mg manufactured by Laser Powder Bed Fusion}}}, year = {{2022}}, } @inbook{52409, author = {{Scionti, Eugenio and Genovese, Matteo and Pellinger, Christoph and Fragiacomo, Petronilla and Schlüter, Alexander}}, booktitle = {{Sustainable and Smart Energy Systems for Europe´s Cities and Rural Areas}}, editor = {{Schlüter, Alexander and Bernabé-Moreno, Juan}}, publisher = {{Hanser-Verlag }}, title = {{{Using More Hydrogen and Green Fuels}}}, year = {{2022}}, } @book{52353, editor = {{Schlüter, Alexander and Bernabé-Moreno, Juan}}, isbn = {{978-3-446-47294-5}}, pages = {{384}}, publisher = {{Hanser}}, title = {{{Sustainable and Smart Energy Systems for Europe's Cities and Rural Areas}}}, doi = {{https://www.hanser-elibrary.com/doi/book/10.3139/9783446471757}}, year = {{2022}}, } @inbook{35964, author = {{Schlegel-Matthies, Kirsten}}, booktitle = {{Konsum - Ernährung - Gesundheit.

As the Nyquist signal has a rectangular bandwidth, it can be multiplexed in the wavelength domain without any guardband as a part of a Nyquist-WDM superchannel. These superchannels can be additionally multiplexed in space and polarization. Thus, the presented demonstration can open a new possibility for the detection of multidimensional parallel data signals with silicon photonics. No external pulse source is needed for the receiver, and frequency-time coherence is used to sample the incoming Nyquist signal with orthogonal sinc-shaped Nyquist pulse sequences. All parameters are completely tunable in the electrical domain. The feasibility of the scheme is demonstrated through a proof-of-concept experiment over the entire C-band (1530 nm–1560 nm), employing a 24 Gbaud Nyquist QPSK signal due to experimental constraints on the transmitter side electronics. However, the silicon Mach-Zehnder modulator with a 3-dB bandwidth of only 16 GHz can process Nyquist signals of 90 GHz optical bandwidth, suggesting a possibility to detect symbol rates up to 90 GBd in an integrated Nyquist receiver.}}, author = {{Misra, Arijit and Kress, Christian and Singh, Karanveer and Meier, Janosch and Schwabe, Tobias and Preussler, Stefan and Scheytt, J.

However, when experimenting with different problem formulations or when prototyping new algorithms, a major practical obstacle is the need to figure out derivatives of objective functions, especially when second‐order derivatives are required. Deriving and manually implementing gradients and Hessians is both time‐consuming and error‐prone. Automatic differentiation techniques address this problem, but can introduce a diverse set of obstacles themselves, e.g. limiting the set of supported language features, imposing restrictions on a program's control flow, incurring a significant run time overhead, or making it hard to exploit sparsity patterns common in geometry processing. We show that for many geometric problems, in particular on meshes, the simplest form of forward‐mode automatic differentiation is not only the most flexible, but also actually the most efficient choice. We introduce TinyAD: a lightweight C++ library that automatically computes gradients and Hessians, in particular of sparse problems, by differentiating small (tiny) sub‐problems. Its simplicity enables easy integration; no restrictions on, e.g., looping and branching are imposed. TinyAD provides the basic ingredients to quickly implement first and second order Newton‐style solvers, allowing for flexible adjustment of both problem formulations and solver details. By showcasing compact implementations of methods from parametrization, deformation, and direction field design, we demonstrate how TinyAD lowers the barrier to exploring non‐linear optimization techniques. This enables not only fast prototyping of new research ideas, but also improves replicability of existing algorithms in geometry processing. TinyAD is available to the community as an open source library.}}, author = {{Schmidt, Patrick and Born, Janis and Bommes, David and Campen, Marcel and Kobbelt, Leif}}, issn = {{0167-7055}}, journal = {{Computer Graphics Forum}}, number = {{5}}, pages = {{113--124}}, publisher = {{Wiley}}, title = {{{TinyAD: Automatic Differentiation in Geometry Processing Made Simple}}}, doi = {{10.1111/cgf.14607}}, volume = {{41}}, year = {{2022}}, } @article{60371, abstract = {{We describe a method for the generation of seamless surface parametrizations with guaranteed local injectivity and full control over holonomy. Previous methods guarantee only one of the two. Local injectivity is required to enable these parametrizations' use in applications such as surface quadrangulation and spline construction. Holonomy control is crucial to enable guidance or prescription of the parametrization's isocurves based on directional information, in particular from cross-fields or feature curves, and more generally to constrain the parametrization topologically. To this end we investigate the relation between cross-field topology and seamless parametrization topology. Leveraging previous results on locally injective parametrization and combining them with insights on this relation in terms of holonomy, we propose an algorithm that meets these requirements. A key component relies on the insight that arbitrary surface cut graphs, as required for global parametrization, can be homeomorphically modified to assume almost any set of turning numbers with respect to a given target cross-field.}}, author = {{Shen, Hanxiao and Zhu, Leyi and Capouellez, Ryan and Panozzo, Daniele and Campen, Marcel and Zorin, Denis}}, issn = {{0730-0301}}, journal = {{ACM Transactions on Graphics}}, number = {{4}}, pages = {{1--12}}, publisher = {{Association for Computing Machinery (ACM)}}, title = {{{Which cross fields can be quadrangulated?}}}, doi = {{10.1145/3528223.3530187}}, volume = {{41}}, year = {{2022}}, }
