Here, a mixture of pure Fe and atomised 316L steel powder is used for PBF-LB to induce a chemical composition gradient in the microstructure. Optical microscopy and μ-CT investigations proved that the samples processed by PBF-LB exhibit very little porosity. Combined EBSD-EDS measurements show the chemical composition gradient leading to the formation of a local fcc-structure. Upon heat treatment (1100 °C, 14 h), the chemical composition is homogeneous throughout the microstructure. A moderate decrease (1060 to 985 MPa) in the sample’s ultimate tensile strength (UTS) is observed after heat treatment. However, the total elongation of the as-built and heat-treated samples remains the same (≈22%). Similarly, a slight decrease in the hardness from 341 to 307 HV1 is observed upon heat treatment.</jats:p>"}],"status":"public","_id":"41492","department":[{"_id":"9"},{"_id":"158"}],"user_id":"43720","language":[{"iso":"eng"}]},{"type":"journal_article","status":"public","_id":"43441","user_id":"43720","department":[{"_id":"158"}],"article_type":"original","article_number":"112043","publication_status":"published","publication_identifier":{"issn":["0042-207X"]},"citation":{"apa":"Šlapáková, M., Kihoulou, B., Veselý, J., Minárik, P., Fekete, K., Knapek, M., Králík, R., Grydin, O., Stolbchenko, M., &#38; Schaper, M.

Its advantages are stability and comparatively low computational cost, however, they require the solution of a nonlinear system of equations. This paper presents a general approach for the construction of third order Runge–Kutta methods by embedding the above mentioned implicit schemes into the class of ELDIRK-methods. These will be defined to have an <jats:italic>Explicit Last</jats:italic> stage in the general Butcher array of <jats:italic>Diagonal Implicit Runge–Kutta</jats:italic> (DIRK) methods, with the consequence, that no additional system of equations must be solved. The main results—valid also for non-linear ordinary differential equations—are as follows: Two extra function calculations are required in order to embed the implicit Euler-method and one extra function calculation is required for the trapezoidal-rule and the Ellsiepen method, in order to obtain the third order properties, respectively. Two numerical examples are concerned with a parachute with viscous damping and a two-dimensional laser beam simulation. Here, we verify the higher order convergence behaviours of the proposed new ELDIRK-methods, and its successful performances for asymptotically exact global error estimation of so-called reversed embedded RK-method are shown.\r\n</jats:p>"}],"status":"public","publication":"Computational Mechanics","type":"journal_article","keyword":["Applied Mathematics","Computational Mathematics","Computational Theory and Mathematics","Mechanical Engineering","Ocean Engineering","Computational Mechanics"],"language":[{"iso":"eng"}],"_id":"45757","department":[{"_id":"9"},{"_id":"154"},{"_id":"321"}],"user_id":"335","year":"2023","citation":{"mla":"Mahnken, Rolf. “Derivation of Third Order Runge–Kutta Methods (ELDIRK) by Embedding of Lower Order Implicit Time Integration Schemes for Local and Global Error Estimation.” <i>Computational Mechanics</i>, Springer Science and Business Media LLC, 2023, doi:<a href=\"https://doi.org/10.1007/s00466-023-02347-2\">10.1007/s00466-023-02347-2</a>.","short":"R.

Life Cycle Engineering (LCE) based on Life Cycle Assessment (LCA) supports this by providing holistic information and improvement potentials regarding eco-efficient products. Key factors influencing LCAs of automotive components, such as material production, will change in the future. First approaches for integrating future scenarios for these key factors into LCE already exist, but they only consider a limited number of parameters and scenarios. This work aims to develop a method that can be practically applied in the industry for integrating prospective LCAs (pLCA) into the LCE of automotive components, considering relevant parameters and consistent scenarios. Therefore, pLCA methods are further developed to investigate the influence of future scenarios on the GHG emissions of automotive components. The practical application is demonstrated for a vehicle component with different design options. This paper shows that different development paths of the foreground and background system can shift the ecological optimum of design alternatives. Therefore, future pathways of relevant parameters must be considered comprehensively to reduce GHG emissions of future vehicles. This work contributes to the methodological and practical integration of pLCA into automotive development processes and provides quantitative results.</jats:p>","lang":"eng"}],"status":"public","publication":"Sustainability","type":"journal_article","title":"Integrating Prospective LCA in the Development of Automotive Components","doi":"10.3390/su151310041","main_file_link":[{"open_access":"1","url":"https://www.mdpi.com/2071-1050/15/13/10041"}],"oa":"1","date_updated":"2023-06-27T06:39:47Z","publisher":"MDPI AG","volume":15,"date_created":"2023-06-27T06:35:20Z","author":[{"last_name":"Grenz","full_name":"Grenz, Julian","first_name":"Julian"},{"id":"44763","full_name":"Ostermann, Moritz","orcid":"https://orcid.org/0000-0003-1146-0443","last_name":"Ostermann","first_name":"Moritz"},{"full_name":"Käsewieter, Karoline","last_name":"Käsewieter","first_name":"Karoline"},{"first_name":"Felipe","full_name":"Cerdas, Felipe","last_name":"Cerdas"},{"first_name":"Thorsten","full_name":"Marten, Thorsten","id":"338","last_name":"Marten"},{"first_name":"Christoph","last_name":"Herrmann","full_name":"Herrmann, Christoph"},{"first_name":"Thomas","last_name":"Tröster","id":"553","full_name":"Tröster, Thomas"}],"year":"2023","intvolume":"        15","citation":{"ieee":"J.

PVVBs are typically generated through the superposition of perfect vortex beams, which suffer from the limited number of topological charges (TCs). Furthermore, dynamic control of PVVBs is desirable and has not been reported. We propose and experimentally demonstrate hybrid grafted perfect vector vortex beams (GPVVBs) and their dynamic control. Hybrid GPVVBs are generated through the superposition of grafted perfect vortex beams with a multifunctional metasurface. The generated hybrid GPVVBs possess spatially variant rates of polarization change due to the involvement of more TCs. Each hybrid GPVVB includes different GPVVBs in the same beam, adding more design flexibility. Moreover, these beams are dynamically controlled with a rotating half waveplate. The generated dynamic GPVVBs may find applications in the fields where dynamic control is in high demand, including optical encryption, dense data communication, and multiple particle manipulation.","lang":"eng"}],"file":[{"success":1,"relation":"main_file","content_type":"application/pdf","file_size":4341041,"access_level":"closed","file_name":"NatureCommun_Ahmed_2023.pdf","file_id":"45869","date_updated":"2023-07-06T06:40:28Z","creator":"zentgraf","date_created":"2023-07-06T06:40:28Z"}],"publication":"Nature Communications","title":"Dynamic control of hybrid grafted perfect vector vortex beams","publisher":"Springer Science and Business Media LLC","date_created":"2023-07-06T06:34:37Z","year":"2023","quality_controlled":"1","issue":"1","article_number":"3915","file_date_updated":"2023-07-06T06:40:28Z","_id":"45868","user_id":"30525","department":[{"_id":"15"},{"_id":"230"},{"_id":"289"},{"_id":"623"}],"status":"public","type":"journal_article","main_file_link":[{"open_access":"1"}],"doi":"10.1038/s41467-023-39599-8","oa":"1","date_updated":"2023-07-06T06:42:10Z","author":[{"first_name":"Hammad","full_name":"Ahmed, Hammad","last_name":"Ahmed"},{"first_name":"Muhammad Afnan","full_name":"Ansari, Muhammad Afnan","last_name":"Ansari"},{"first_name":"Yan","full_name":"Li, Yan","last_name":"Li"},{"first_name":"Thomas","id":"30525","full_name":"Zentgraf, Thomas","last_name":"Zentgraf","orcid":"0000-0002-8662-1101"},{"full_name":"Mehmood, Muhammad Qasim","last_name":"Mehmood","first_name":"Muhammad Qasim"},{"first_name":"Xianzhong","last_name":"Chen","full_name":"Chen, Xianzhong"}],"volume":14,"citation":{"apa":"Ahmed, H., Ansari, M.

In practical simulations, several trillions of ERIs may have to be\r\ncomputed for every time step.\r\nIn this work, we investigate FPGAs as accelerators for the ERI computation. We use template parameters, here within the Intel oneAPI tool flow, to create customized designs for 256 different ERI quartet classes, based on their orbitals. To maximize data reuse, all intermediates are buffered in FPGA on-chip memory with customized layout. The pre-calculation of intermediates also helps to overcome data dependencies caused by multi-dimensional recurrence\r\nrelations. The involved loop structures are partially or even fully unrolled for high throughput of FPGA kernels. Furthermore, a lossy compression algorithm utilizing arbitrary bitwidth integers is integrated in the FPGA kernels. To our\r\nbest knowledge, this is the first work on ERI computation on FPGAs that supports more than just the single most basic quartet class. Also, the integration of ERI computation and compression it a novelty that is not even covered by CPU or GPU libraries so far.\r\nOur evaluation shows that using 16-bit integer for the ERI compression, the fastest FPGA kernels exceed the performance of 10 GERIS ($10 \\times 10^9$ ERIs per second) on one Intel Stratix 10 GX 2800 FPGA, with maximum absolute errors around $10^{-7}$ - $10^{-5}$ Hartree. The measured throughput can be accurately explained by a performance model. The FPGA kernels deployed on 2 FPGAs outperform similar computations using the widely used libint reference on a two-socket server with 40 Xeon Gold 6148 CPU cores of the same process technology by factors up to 6.0x and on a new two-socket server with 128 EPYC 7713 CPU cores by up to 1.9x."}]},{"quality_controlled":"1","year":"2023","publisher":"SAGE Publications","date_created":"2023-05-30T09:19:09Z","title":"Breaking the exascale barrier for the electronic structure problem in ab-initio molecular dynamics","publication":"The International Journal of High Performance Computing Applications","abstract":[{"lang":"eng","text":"<jats:p> The non-orthogonal local submatrix method applied to electronic structure–based molecular dynamics simulations is shown to exceed 1.1 EFLOP/s in FP16/FP32-mixed floating-point arithmetic when using 4400 NVIDIA A100 GPUs of the Perlmutter system.
