One example relevant to the automobile industry is the United Nations Economic Commission of Europe (UN ECE), which specifies the homologation of automobile series and requires proof of traceability. The required traceability can be achieved by modeling system artifacts and their relations in a consistent, seamless model—an effect-chain model. Currently, no in-depth methodology exists to support engineers in developing certification-compliant effect-chain models. For this purpose, a new methodology for certification-compliant effect-chain modeling was developed, which includes extensions of an existing method, suitable models, and tools to support engineers in the modeling process. For evaluation purposes, applicability is proven based on the experience of more than 300 workshops at an automotive OEM and an automotive supplier. The following case example is chosen to demonstrate applicability: the development of a window lifter that has to meet the demands of UN ECE Regulations R156 and R21. Results indicate multiple benefits in supporting engineers with the certification-compliant modeling of effect chains. Three benefits are goal-oriented modeling to reduce the necessary modeling capacity, increasing model quality by applying information quality criteria, and the potential to reduce costs through automatable effect-chain analyses for technical changes. Further, companies in the automotive and other industries will benefit from increased modeling capabilities that can be used for architecture modeling and to comply with other regulations such as ASPICE or ISO 26262.' article_number: '154' author: - first_name: Iris full_name: Gräßler, Iris id: '47565' last_name: Gräßler orcid: 0000-0001-5765-971X - first_name: Dominik full_name: Wiechel, Dominik id: '67161' last_name: Wiechel - first_name: Anna-Sophie full_name: Koch, Anna-Sophie id: '44158' last_name: Koch - first_name: Tim full_name: Sturm, Tim last_name: Sturm - first_name: Thomas full_name: Markfelder, Thomas last_name: Markfelder citation: ama: Gräßler I, Wiechel D, Koch A-S, Sturm T, Markfelder T.

In this paper, an approach for a future traffic control system for mixed autonomy traffic environments is presented. Furthermore, a simulation framework based on the city of Paderborn is introduced to enable the development and examination of such a system. This encompasses multiple elements including the road network itself, traffic lights, sensors as well as methods to analyse the topology of the network. Furthermore, a procedure for traffic demand generation and routing is presented based on statistical data of the city and traffic data obtained by measurements. The resulting model can receive and apply the generated control inputs and in turn generates simulated sensor data for the control system based on the current system state. author: - first_name: Christopher full_name: Link, Christopher id: '38249' last_name: Link - first_name: Kevin full_name: Malena, Kevin id: '36303' last_name: Malena orcid: 0000-0003-1183-4679 - first_name: Sandra full_name: Gausemeier, Sandra id: '17793' last_name: Gausemeier - first_name: Ansgar full_name: Trächtler, Ansgar id: '552' last_name: Trächtler citation: ama: 'Link C, Malena K, Gausemeier S, Trächtler A.

Several introduction strategies are available in the literature; nevertheless, the introduction of Systems Engineering into practice still poses a great challenge to companies. Many companies have already gained experience in the introduction of Systems Engineering. Therefore, as part of the SE4OWL research project, the need to conduct a study including expert interviews and to collect the experiences of experts was identified. A total of 78 hypotheses were identified from 13 expert interviews concerning the lessons learned. Using exclusion criteria, 52 hypotheses were validated in a subsequent quantitative survey with 112 participants. Of these 52 hypotheses, 40 could be confirmed based on the survey results. Only four hypotheses were rejected, and eight could neither be confirmed nor rejected. Through this research, guidance is provided to companies to leverage best practices for the introduction of their own Systems Engineering and to avoid the poor practices of other companies. article_number: '119' author: - first_name: Daria full_name: Wilke, Daria last_name: Wilke - first_name: Robin full_name: Grothe, Robin last_name: Grothe - first_name: Lukas full_name: Bretz, Lukas last_name: Bretz - first_name: Harald full_name: Anacker, Harald last_name: Anacker - first_name: Roman full_name: Dumitrescu, Roman id: '16190' last_name: Dumitrescu citation: ama: Wilke D, Grothe R, Bretz L, Anacker H, Dumitrescu R.

They comprise two conventional structured packings with different specific geometrical surface areas. In this work, the complex fluid dynamics in sandwich packings is modeled using a novel approach based on a one-dimensional, steady momentum balance of the liquid and gas phases. The interactions between the three present phases (gas, liquid, and solid) are considered by closures incorporated into the momentum balance. The formulation of these closures is derived from two fluid-dynamic analogies for the film and froth flow patterns. The adjustable parameters in the closures are regressed for the film flow using dry pressure drop measurements and liquid hold-up data in trickle flow conditions. For the froth flow, the tuning parameters are fitted to overall pressure drop measurements and local liquid hold-up data acquired from ultra-fast X-ray tomography (UFXCT). The model predicts liquid hold-up and pressure drop data with an average relative deviation of 16.4 % and 19 %, respectively. Compared to previous fluid dynamic models for sandwich packings, the number of adjustable parameters could be reduced while maintaining comparable accuracy." author: - first_name: Patrick full_name: Franke, Patrick id: '93922' last_name: Franke - first_name: Iman full_name: Shabanilemraski, Iman last_name: Shabanilemraski - first_name: Markus full_name: Schubert, Markus last_name: Schubert - first_name: Uwe full_name: Hampel, Uwe last_name: Hampel - first_name: Eugeny Y. full_name: Kenig, Eugeny Y. id: '665' last_name: Kenig citation: ama: Franke P, Shabanilemraski I, Schubert M, Hampel U, Kenig EY.

A promising\r\nprocess to manufacture these nanoparticles is flame spray pyrolysis (FSP). A lack of understanding of the\r\nindividual sub-processes in FSP makes it challenging to tailor nanoparticle properties. This work provides\r\ninsights into the formation of iron oxide nanoparticles in a turbulent spray flame using Large Eddy Simulations\r\n(LES), which are based on a comprehensive model, including customized submodels. Highlights are the\r\nadaption of a turbulent combustion model and a bivariate hybrid method of moments for modeling nanoparticle\r\ndynamics. The work focuses on the SpraySyn burner, which is a standardized laboratory burner and was\r\noperated with a precursor-solvent mixture of ethanol and iron(III) nitrate nonahydrate. For studying the\r\nrelevance of precursor chemistry, LES using an evaporation-limited precursor chemistry model is compared\r\nwith a model that includes detailed iron chemistry. A further novelty is the inclusion of adsorption in the\r\nsimulation, which defines a third model for comparison. Sufficient validation is achieved for the undoped LES\r\nusing experimental data from the literature. A strong impact of the detailed iron chemistry and adsorption\r\nis found on the precursor consumption and the aggregate and primary particle formation. Comparing the\r\nparticle diameters with experimental measurements from the literature and data generated for this work is\r\nfound unsuitable to asses the precursor chemistry model and revealed an urgent need for future experimental\r\nand numerical research. This work serves as a step forward in realizing a reliable model." citation: ama: Fröde F, Grenga T, Pitsch H, et al., eds. Large Eddy Simulation of Iron Oxide Formation in a Laboratory Spray Flame.

Despite these limitations and specificities, humans get things done through collaboration and the creative use of the environment. While multiuser interactive VR is attracting greater numbers of participants, there are currently few attempts to analyze the in situ interaction systematically. This paper proposes a video-analytic detail-oriented methodological framework for studying virtual reality interaction. Using multimodal conversation analysis, the paper investigates a nonverbal, embodied, two-person interaction: two players in a survival game strive to gesturally resolve a misunderstanding regarding an in-game mechanic—however, both of their microphones are turned off for the duration of play. The players’ inability to resort to complex language to resolve this issue results in a dense sequence of back-and-forth activity involving gestures, object manipulation, gaze, and body work. Most crucially, timing and modified repetitions of previously produced actions turn out to be the key to overcome both technical and communicative challenges. The paper analyzes these action sequences, demonstrates how they generate intended outcomes, and proposes a vocabulary to speak about these types of interaction more generally. The findings demonstrate the viability of multimodal analysis of VR interaction, shed light on unique challenges of analyzing interaction in virtual reality, and generate broader methodological insights about the study of nonverbal action.' article_type: original author: - first_name: Nils full_name: Klowait, Nils id: '98454' last_name: Klowait orcid: 0000-0002-7347-099X citation: ama: Klowait N.

The requirements have to be documented and validated carefully using a systematic requirements engineering (RE) approach, for example, by applying scenario-based requirements notations. The resources of the execution platforms and their properties (e.g., CPU frequency or bus throughput) induce effects on the timing behavior, which may lead to violations of the real-time requirements. Nowadays, the platform properties and their induced timing effects are verified against the real-time requirements by means of timing analysis techniques mostly implemented in commercial-off-the-shelf tools. However, such timing analyses are conducted in late development phases since they rely on artifacts produced during these phases (e.g., the platform-specific code). In order to enable early timing analyses already during RE, we extend a scenario-based requirements notation with allocation means to platform models and define operational semantics for the purpose of simulation-based, platform-aware timing analyses. We illustrate and evaluate the approach with an automotive software-intensive system. author: - first_name: Jörg full_name: Holtmann, Jörg id: '3875' last_name: Holtmann orcid: 0000-0001-6141-4571 - first_name: Julien full_name: Deantoni, Julien last_name: Deantoni - first_name: Markus full_name: Fockel, Markus id: '8472' last_name: Fockel orcid: 0000-0002-1269-0702 citation: ama: Holtmann J, Deantoni J, Fockel M.

These parameters can then be used to optimize inductive applications such as wireless power transmission. The focus here will be on inductive localization, which uses high-frequency magnetic fields and the resulting induced voltage to provide localization through the coupling parameter mutual inductance. To achieve localization with high accuracy and best possible operation (resonance, signal strength, etc.), the coil parameters need to be well known. For this reason, some numerical methods for the calculation of these quantities are presented and validated. In addition, the physical effects are thereby considered in more detail, allowing the localization procedure to be better optimized compared to simulative black-box methods. The goal should be a dedicated simulation platform for planar coils to be able to develop training data for neural networks and to test and optimize localization algorithms. author: - first_name: Sven full_name: Lange, Sven id: '38240' last_name: Lange - first_name: Christian full_name: Hedayat, Christian last_name: Hedayat - first_name: Harald full_name: Kuhn, Harald last_name: Kuhn - first_name: Ulrich full_name: Hilleringmann, Ulrich last_name: Hilleringmann citation: ama: 'Lange S, Hedayat C, Kuhn H, Hilleringmann U.

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.

Previous related literature has provided profound knowledge in cases when the system is augmented with no-flux/no-flux/no-slip boundary conditions for the density of cells, the chemical concentration and the fluid velocity field, respectively; in particular, available qualitative results strongly indicate that only trivial solution behavior can be expected on large time scales. In line with refined modeling approaches to oxygen evolution near fluid-air interfaces, this study now focuses on situations involving a fixed chemoattractant concentration on the boundary. Despite an apparent loss of mathematically favorable energy structures thereby induced, by means of an alternative variational approach a basic theory of global existence is developed in a natural framework of weak solvability. Beyond this, some additional qualitative information on the large time behavior of these solutions is derived by identifying a certain global relaxation property. Specifically, a second result asserts, within a suitable topological setting, the existence of a bounded set which eventually absorbs each individual of the obtained trajectories, and the diameter of which is bounded only by the physically relevant quantities of total population size and prescribed boundary concentration of the chemical signal. author: - first_name: Tobias full_name: Black, Tobias id: '23686' last_name: Black orcid: 0000-0001-9963-0800 - first_name: Michael full_name: Winkler, Michael id: '31496' last_name: Winkler citation: ama: Black T, Winkler M.

Relative movements take place at the chain joint between pin and bush, which lead to wear of the chain joint due to friction and so to chain elongation. The chain joint is generally lubricated with oils, through which elastohydrodynamic processes can occur in the gap between the pin and the bush of the chain joint. A simulation model is developed here to examine these elastohydrodynamic processes considering a mass conserving cavitation model, the Newtonian flow behaviour of the lubricant and the structuring of the bush surface, whereby the real form of the bush is considered. MBS simulations are used to obtain realistic loads on the chain joint. author: - first_name: Lionel full_name: Simo Kamga, Lionel last_name: Simo Kamga - first_name: Dominik full_name: Meffert, Dominik last_name: Meffert - first_name: Balázs full_name: Magyar, Balázs id: '97759' last_name: Magyar - first_name: Manuel full_name: Oehler, Manuel last_name: Oehler - first_name: Bernd full_name: Sauer, Bernd last_name: Sauer citation: ama: Simo Kamga L, Meffert D, Magyar B, Oehler M, Sauer B.

The model is derived from basic thermodynamical principles and consists of a convected Cahn–Hilliard equation with source terms for the tumor cells and a convected reaction–diffusion equation with boundary supply for the nutrient. Chemotactic terms, which are essential for the invasive behavior of tumors, are taken into account. The model is completed by a viscoelastic system consisting of the Navier–Stokes equation for the hydrodynamic quantities, and a general constitutive equation with stress relaxation for the left Cauchy–Green tensor associated with the elastic part of the total mechanical response of the viscoelastic material. For a specific choice of the elastic energy density and with an additional dissipative term accounting for stress diffusion, we prove existence of global-in-time weak solutions of the viscoelastic model for tumor growth in two space dimensions [Formula: see text] by the passage to the limit in a fully-discrete finite element scheme where a CFL condition, i.e. [Formula: see text], is required. Moreover, in arbitrary dimensions [Formula: see text], we show stability and existence of solutions for the fully-discrete finite element scheme, where positive definiteness of the discrete Cauchy–Green tensor is proved with a regularization technique that was first introduced by Barrett and Boyaval [Existence and approximation of a (regularized) Oldroyd-B model, Math. Models Methods Appl. Sci. 21 (2011) 1783–1837]. After that, we improve the regularity results in arbitrary dimensions [Formula: see text] and in two dimensions [Formula: see text], where a CFL condition is required. Then, in two dimensions [Formula: see text], we pass to the limit in the discretization parameters and show that subsequences of discrete solutions converge to a global-in-time weak solution. Finally, we present numerical results in two dimensions [Formula: see text].
