--- _id: '63890' abstract: - lang: eng text: The computation of highly contracted electron repulsion integrals (ERIs) is essential to achieve quantum accuracy in atomistic simulations based on quantum mechanics. Its growing computational demands make energy efficiency a critical concern. Recent studies demonstrate FPGAs’ superior performance and energy efficiency for computing primitive ERIs, but the computation of highly contracted ERIs introduces significant algorithmic complexity and new design challenges for FPGA acceleration.In this work, we present SORCERI, the first streaming overlay acceleration for highly contracted ERI computations on FPGAs. SORCERI introduces a novel streaming Rys computing unit to calculate roots and weights of Rys polynomials on-chip, and a streaming contraction unit for the contraction of primitive ERIs. This shifts the design bottleneck from limited CPU-FPGA communication bandwidth to available FPGA computation resources. To address practical deployment challenges for a large number of quartet classes, we design three streaming overlays, together with an efficient memory transpose optimization, to cover the 21 most commonly used quartet classes in realistic atomistic simulations. To address the new computation constraints, we use flexible calculation stages with a free-running streaming architecture to achieve high DSP utilization and good timing closure.Experiments demonstrate that SORCERI achieves an average 5.96x, 1.99x, and 1.16x better performance per watt than libint on a 64-core AMD EPYC 7713 CPU, libintx on an Nvidia A40 GPU, and SERI, the prior best-performing FPGA design for primitive ERIs. Furthermore, SORCERI reaches a peak throughput of 44.11 GERIS (109 ERIs per second) that is 1.52x, 1.13x, and 1.93x greater than libint, libintx and SERI, respectively.

This study addresses the formation of “viscous fingering” instabilities in structural adhesive joints, which are induced by thermally driven relative displacements during the liquid phase of the adhesive. Using a component-like specimen “bridge specimen,” the dependency of this phenomenon on process temperature and structural stiffness (rivet distance) was characterized. Experimental results reveal that while the relative displacement scales cubically with the free buckling length, the resulting adhesive area reduction follows an exponential trend, leading to a loss of effective bond area of up to 79%, which significantly compromises the joint strength in automotive applications. To predict these process-induced defects, a thermo-chemo-viscoelastic-viscoplastic adhesive model implemented in LS-DYNA was applied. The model combines curing kinetics, viscoelastic relaxation, and pressure-dependent plasticity and features a geometric damage parameter (D) that captures the adhesive area reduction caused by viscous fingering as an exponential function of the accumulated normal strain in the liquid phase. This damage parameter, calibrated on base-specimen level, was transferred to the component geometry. The simulation demonstrated high predictive accuracy with a maximum deviation of the adhesive area reduction of 3.1% compared to experimental data. This validates the model’s capability to predict manufacturing-induced damage in complex hybrid structures solely based on thermal boundary conditions. article_type: original author: - first_name: Mohamad full_name: Al Trjman, Mohamad id: '65415' last_name: Al Trjman - first_name: Felix full_name: Beule, Felix id: '66192' last_name: Beule - first_name: Dominik full_name: Teutenberg, Dominik id: '537' last_name: Teutenberg - first_name: Gerson full_name: Meschut, Gerson id: '32056' last_name: Meschut orcid: 0000-0002-2763-1246 - first_name: Julia full_name: Riese, Julia id: '101499' last_name: Riese orcid: 0000-0002-3053-0534 citation: ama: Al Trjman M, Beule F, Teutenberg D, Meschut G, Riese J.

In Germany, where 80 % of household energy goes to space heating and hot water, shifting to low-carbon solutions is crucial. Fossil-fuelled district heating networks can incorporate renewable energy via heat pumps, improving efficiency. Although heat pump design typically favours minimal temperature lifts, higher lifts can be economically viable with low electricity prices and abundant renewables. Adding thermal energy storage boosts operational flexibility. This study explores a flexible heat pump operation incorporating part load behaviour with a thermal energy storage in a German city’s district heating system to minimise costs and carbon dioxide emissions. Using a mixed-integer linear programming model, it examines the impact of temperature adjustments and storage on system efficiency. The results show that the integration of a heat pump in a district heating system reduces operating costs. Compared to a supply without a heat pump, with levelised cost of heating of 9.98 cent/kWhth and a fixed operating mode with costs between 9.96 cent/kWhth and 11.49 cent/kWhth, the flexible use results in lowest costs of 9.85 cent/kWhth, while also reducing overall CO2 emissions. Using a full factorial sensitivity analysis, the levelised cost of heating ranged between 9.15 cent/kWhth in the best case and 10.37 cent/kWhth in the worst case for the selected configuration. article_number: '121714' article_type: original author: - first_name: Henning Christoph full_name: Rahlf, Henning Christoph id: '56955' last_name: Rahlf orcid: 0009-0006-8106-2132 - first_name: Denis full_name: Divkovic, Denis id: '89059' last_name: Divkovic - first_name: Lukas full_name: Knorr, Lukas id: '90391' last_name: Knorr orcid: 0009-0005-4727-7511 - first_name: Florian full_name: Schlosser, Florian id: '88614' last_name: Schlosser - first_name: Henning full_name: Meschede, Henning id: '86954' last_name: Meschede orcid: 0000-0002-1538-089X citation: ama: Rahlf HC, Divkovic D, Knorr L, Schlosser F, Meschede H.

Private households are central to this transition, combining dynamic consumption with decentralised generation. This paper presents a multi-agent microgrid simulation built on the Mesa framework, focusing on the heterogeneous objectives and technological capabilities of residential participants. Households are modelled as autonomous agents with individual strategies, while a dedicated “grid agent” represents the distribution system operator and regulates the microgrid in a grid-supportive manner. The emission factor serves as the key indicator for grid-friendly behaviour. Results show that in summer, unmanaged PV feed-in from heterogeneous households causes substantial grid stress and balancing effort for the distribution system operator. Dynamic electricity prices can incentivise grid-friendly dispatch, but their effectiveness depends on the correlation between price signals and renewable availability and cannot guarantee grid-supportive behaviour alone. The grid agent reliably improves the grid-supportive coefficient, yet its operating strategy, for instance additional peak-reduction objectives, can interfere with price-based incentives. Effective demand-side management therefore requires careful analysis of stakeholder interactions. Building on this insight, thepaper provides a basic framework for the design, implementation, and assessment of both integrated and individual energy management strategies within a microgrid environment. By simulating the dynamic interactions among system participants and strategies, it enables comprehensive evaluation of their collective impact on the grid, supporting the development of robust solutions for future electricity networks. author: - first_name: Kevin full_name: Henne, Kevin id: '56918' last_name: Henne - first_name: Henning Christoph full_name: Rahlf, Henning Christoph id: '56955' last_name: Rahlf orcid: 0009-0006-8106-2132 - first_name: Marius full_name: Naumann, Marius id: '94950' last_name: Naumann - first_name: Henning full_name: Meschede, Henning id: '86954' last_name: Meschede orcid: 0000-0002-1538-089X citation: ama: 'Henne K, Rahlf HC, Naumann M, Meschede H.

Leveraging such engineering simulation data in strategic product planning can support idea generation and early evaluation of design alternatives and limitations. However, limited resources and expertise hinder broader uptake in strategic product planning. This paper investigates simulator integration into automated workflows and key processing components to enable simulation without in-depth expertise. This approach improves strategic product planning by creating data-based decision support." author: - first_name: Iris full_name: Gräßler, Iris id: '47565' last_name: Gräßler orcid: 0000-0001-5765-971X - first_name: Niklas full_name: Döhner, Niklas id: '108017' last_name: Döhner orcid: https://orcid.org/0009-0005-7676-4036 citation: ama: 'Gräßler I, Döhner N.

It introduces the concept of \"meta-modalities\" which encapsulate\r\nadditional forms of feedback beyond the traditional preference and scalar\r\nfeedback mechanisms. Unlike prior research that focused on individual\r\nmeta-modalities, this work evaluates their combined effect on learning\r\noutcomes. Through a study with human participants, we explore user preferences\r\nfor these modalities and their impact on robot learning performance. Our\r\nfindings reveal that while individual modalities are perceived differently,\r\ntheir combination significantly improves learning behavior and usability.

Dedicated multi-FPGA clusters provide inter-FPGA networks for direct device to device communication. The oneAPI high-level synthesis toolchain offers I/O pipes to allow user kernels to interact with the networking ports of the FPGA board. In this work, we evaluate using oneAPI I/O pipes for direct FPGA-to-FPGA communication by scaling a SYCL implementation of a Jacobi solver on up to 25 FPGAs in the Noctua 2 cluster.

This paper describes in detail the overall setup of Noctua 2 and gives insights into the operation of the cluster from a hardware, software and facility perspective.' article_type: original author: - first_name: Carsten full_name: Bauer, Carsten id: '90082' last_name: Bauer - first_name: Tobias full_name: Kenter, Tobias id: '3145' last_name: Kenter - first_name: Michael full_name: Lass, Michael id: '24135' last_name: Lass orcid: 0000-0002-5708-7632 - first_name: Lukas full_name: Mazur, Lukas id: '90492' last_name: Mazur orcid: ' 0000-0001-6304-7082' - first_name: Marius full_name: Meyer, Marius id: '40778' last_name: Meyer - first_name: Holger full_name: Nitsche, Holger id: '15272' last_name: Nitsche - first_name: Heinrich full_name: Riebler, Heinrich id: '8961' last_name: Riebler - first_name: Robert full_name: Schade, Robert id: '75963' last_name: Schade orcid: 0000-0002-6268-5397 - first_name: Michael full_name: Schwarz, Michael id: '5312' last_name: Schwarz - first_name: Nils full_name: Winnwa, Nils id: '61189' last_name: Winnwa - first_name: Alex full_name: Wiens, Alex id: '23522' last_name: Wiens orcid: 0000-0003-1764-9773 - first_name: Xin full_name: Wu, Xin id: '77439' last_name: Wu - first_name: Christian full_name: Plessl, Christian id: '16153' last_name: Plessl orcid: 0000-0001-5728-9982 - first_name: Jens full_name: Simon, Jens id: '15273' last_name: Simon citation: ama: Bauer C, Kenter T, Lass M, et al.

Business reputation ecosystems are a widely untapped research field. In these ecosystems, agents can selectively exchange (monetary) ratings to in-form about the experienced quality in a market. We build a model for conducting a multi-agent simulation that can be used to simulate and evaluate business rep-utation ecosystems as a new system class. We explore the factual occurring vol-untary payment to create positive (pay) or negative ratings (no pay), selling rat-ings selectively to alleviate information asymmetry, and the workings of counter-ratings to prevent buyers' dishonest ratings. Thereby, we analyze, among others, agent profitability, the occurrence of dishonest ratings, and reputation bias and sensitivity. The results provide simulation-based empirical evidence that the con-cept of monetary reputation systems provides necessary incentives for participa-tion, and high-quality sellers and honest buyers benefit from such a system. The results indicate that counter-ratings prompt buyers author: - first_name: Ulvi full_name: Ibrahimli, Ulvi last_name: Ibrahimli - first_name: Simon full_name: Hemmrich, Simon last_name: Hemmrich - first_name: Simon full_name: Zauke, Simon last_name: Zauke - first_name: Axel full_name: Winkelmann, Axel last_name: Winkelmann citation: ama: 'Ibrahimli U, Hemmrich S, Zauke S, Winkelmann A.

Abgesehen von den konventionellen Methoden um einen Trojaner in eine Schaltung für ein Field-programmable Gate Array (FPGA) einzuschleusen, können auch die Entwurfswerkzeuge heimlich kompromittiert werden um einen Angreifer dabei zu unterstützen einen erfolgreichen Angriff durchzuführen, der zum Beispiel Fehlfunktionen oder ungewollte Informationsabflüsse bewirken kann. Diese Dissertation beschäftigt sich hauptsächlich mit den beiden Blickwinkeln auf Hardwaretrojaner in rekonfigurierbaren Systemen, einerseits der Perspektive des Verteidigers mit einer Methode zur Erkennung von Trojanern auf der Bitstromebene, und andererseits derjenigen des Angreifers mit einer neuartigen Angriffsmethode für FPGA Trojaner. Für die Verteidigung gegen den Trojaner ``Heimtückische LUT'''' stellen wir die allererste erfolgreiche Gegenmaßnahme vor, die durch Verifikation mittels Proof-carrying Hardware (PCH) auf der Bitstromebene direkt vor der Konfiguration der Hardware angewendet werden kann, und präsentieren ein vollständiges Schema für den Entwurf und die Verifikation von Schaltungen für iCE40 FPGAs. Für die Gegenseite führen wir einen neuen Angriff ein, welcher bösartiges Routing im eingefügten Trojaner ausnutzt um selbst im fertigen Bitstrom in einem inaktiven Zustand zu verbleiben: Hierdurch kann dieser neuartige Angriff zur Zeit weder von herkömmlichen Test- und Verifikationsmethoden, noch von unserer vorher vorgestellten Verifikation auf der Bitstromebene entdeckt werden.' - lang: eng text: The battle of developing hardware Trojans and corresponding countermeasures has taken adversaries towards ingenious ways of compromising hardware designs by circumventing even advanced testing and verification methods. Besides conventional methods of inserting Trojans into a design by a malicious entity, the design flow for field-programmable gate arrays (FPGAs) can also be surreptitiously compromised to assist the attacker to perform a successful malfunctioning or information leakage attack. This thesis mainly focuses on the two aspects of hardware Trojans in reconfigurable systems, the defenders perspective which corresponds to the bitstream-level Trojan detection technique, and the attackers perspective which corresponds to a novel FPGA Trojan attack. From the defender's perspective, we introduce a first-ever successful pre-configuration countermeasure against the ``Malicious LUT''-hardware Trojan, by employing bitstream-level Proof-Carrying Hardware (PCH) and present the complete design-and-verification flow for iCE40 FPGAs. Likewise, from an attackers perspective, we present a novel attack that leverages malicious routing of the inserted Trojan circuit to acquire a dormant state even in the generated and transmitted bitstream. Since the Trojan is injected in a post-synthesis step and remains unconnected in the bitstream, the presented attack can currently neither be prevented by conventional testing and verification methods nor by bitstream-level verification techniques. author: - first_name: Qazi Arbab full_name: Ahmed, Qazi Arbab id: '72764' last_name: Ahmed orcid: 0000-0002-1837-2254 citation: ama: Ahmed QA.

As a result of this success, more and more companies want to build their own platforms and participate in the success. However, building and operating a digital platform involves multiple challenges and most of such ambitions fail. Since most digital platforms fail, strategic leadership of digital platforms must consider both success factors and reasons for platform failure. For this purpose, we conducted a systematic literature analysis and identified 24 success as well as failure factors in 9 dimensions. From a scientific perspective, the article provides a structured analysis of success and failure factors of digital platforms, which previously did not exist in literature. Practitioners can use the resulting knowledge base to successfully manage platform activities and avoid pitfalls. author: - first_name: Leon full_name: Özcan, Leon id: '45137' last_name: Özcan - first_name: Christian full_name: Koldewey, Christian last_name: Koldewey - first_name: Estelle full_name: Duparc, Estelle last_name: Duparc - first_name: Hendrik full_name: van der Valk, Hendrik last_name: van der Valk - first_name: Boris full_name: Otto, Boris last_name: Otto - first_name: Roman full_name: Dumitrescu, Roman last_name: Dumitrescu citation: ama: 'Özcan L, Koldewey C, Duparc E, van der Valk H, Otto B, Dumitrescu R.

The demand for precise predictions increases with the desire of lightweight design in transportation due to environmental protection. Corrosion with its manifold of mechanisms often occurs together with the production of hydrogen by electrochemical reactions. Hydrogen embrittlement is one of the most feared damage mechanisms for metal constructions often leading to early and unexpected failure. Until now, predictions are mostly based on costly experiments. Hence, a rational predictive model based on the fundamentals of electrochemistry and damage mechanics has to be developed in order to reduce the costs. In this work, a first model approach based on classical continuum damage mechanics is presented to couple both, the damage induced by the mechanical stress and the hydrogen embrittlement. An elaborated two-scale model based on the selfconsistent theory is applied to describe the mechanical damage due to fatigue. The electrochemical kinetics are elucidated through the Langmuir adsorption isotherm and the diffusion equation to consider the impact of hydrogen embrittlement on the fatigue. The modeling of the mechanism of hydrogen embrittlement defines the progress of damage accumulation due to the electrochemistry. The durability results like the S-N diagram show the influence of hydrogen embrittlement by varying, e.g. the fatigue frequency or the stress ratio. author: - first_name: Yuhao full_name: Shi, Yuhao last_name: Shi - first_name: Sven full_name: Harzheim, Sven last_name: Harzheim - first_name: Martin full_name: Hofmann, Martin last_name: Hofmann - first_name: Thomas full_name: Wallmersperger, Thomas last_name: Wallmersperger citation: ama: 'Shi Y, Harzheim S, Hofmann M, Wallmersperger T.

We illustrate why commonly used diversity measures are not entirely appropriate for this task and propose a sophisticated basin-based evaluation (BBE) method. Also, BBE variants are developed, capturing the anytime behavior of algorithms. The set of BBE measures is tested by means of an algorithm configuration study. We show that these new measures also transfer properties of the well-established hypervolume (HV) indicator to the domain of MMMOO, thus also accounting for objective space convergence. Moreover, we advance MMMOO research by providing insights into the multimodal performance of the considered algorithms. Specifically, algorithms exploiting local structures are shown to outperform classical evolutionary multi-objective optimizers regarding the BBE variants and respective trade-off with HV. author: - first_name: Jonathan full_name: Heins, Jonathan last_name: Heins - first_name: Jeroen full_name: Rook, Jeroen last_name: Rook - first_name: Lennart full_name: Schäpermeier, Lennart last_name: Schäpermeier - first_name: Pascal full_name: Kerschke, Pascal last_name: Kerschke - first_name: Jakob full_name: Bossek, Jakob id: '102979' last_name: Bossek orcid: 0000-0002-4121-4668 - first_name: Heike full_name: Trautmann, Heike last_name: Trautmann citation: ama: 'Heins J, Rook J, Schäpermeier L, Kerschke P, Bossek J, Trautmann H.
