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.

But due to the lack of open and compatible simulators, authors typically create their own simulation environments for training and evaluation. This is cumbersome and time-consuming for authors and limits reproducibility and comparability, ultimately impeding progress in the field.\r\n\r\nTo this end, we propose mobile-env, a simple and open platform for training, evaluating, and comparing reinforcement learning and conventional approaches for continuous control in mobile wireless networks. mobile-env is lightweight and implements the common OpenAI Gym interface and additional wrappers, which allows connecting virtually any single-agent or multi-agent reinforcement learning framework to the environment. While mobile-env provides sensible default values and can be used out of the box, it also has many configuration options and is easy to extend. We therefore believe mobile-env to be a valuable platform for driving meaningful progress in autonomous coordination of\r\nwireless mobile networks." author: - first_name: Stefan Balthasar full_name: Schneider, Stefan Balthasar id: '35343' last_name: Schneider orcid: 0000-0001-8210-4011 - first_name: Stefan full_name: Werner, Stefan last_name: Werner - first_name: Ramin full_name: Khalili, Ramin last_name: Khalili - first_name: Artur full_name: Hecker, Artur last_name: Hecker - first_name: Holger full_name: Karl, Holger id: '126' last_name: Karl citation: ama: 'Schneider SB, Werner S, Khalili R, Hecker A, Karl H. mobile-env: An Open Platform for Reinforcement Learning in Wireless Mobile Networks.
