Der Beitrag rekonstruiert in einem ersten Schritt, wie und welche Diversity-Dimensionen in Akkreditierungskriterien abgebildet wurden. Hierzu wurden die Hochschulrahmengesetze, die ländergemeinsamen Strukturvorgaben der Kultusministerkonferenz, die Akkreditierungskriterien sowie Tätigkeitsberichte und Protokolle des Akkreditierungsrates mittels einer Dokumentenanalyse ausgewertet.

In many cases, the efficiency of the melting process acts as the primary throughput-limiting factor. If the material melts too late in the process, it may not be sufficiently mixed, resulting in substandard product quality. Accurate prediction of the melting process is therefore essential for efficient and cost-effective machine design. A practical method for engineers is the modeling of the melting process using mathematical–physical models that can be solved without complex numerical methods. These models enable rapid calculations while still providing sufficient predictive accuracy. This study revisits the modified Tadmor model by Potente, which describes the melting process and predicts the delay-zone length, extending from the hopper front edge to the point of melt pool formation. Based on extensive experimental investigations, this model is adapted by redefining the flow temperatures at the phase boundary and accounting for surface porosity at the beginning of the melting zone. Additionally, the effect of variable solid bed dynamics on model accuracy is examined. Significant model improvements were achieved by accounting for reduced heat flow into the solid bed due to the porous surface structure in the solid conveying zone, along with a new assumption for the flow temperature at the phase boundary between the solid bed and melt film.","lang":"eng"}],"status":"public","publication":"Polymers","type":"journal_article","keyword":["delay zone","extrusion","melting modeling"],"language":[{"iso":"eng"}],"_id":"59243","department":[{"_id":"9"},{"_id":"321"},{"_id":"367"}],"user_id":"59363","year":"2024","intvolume":"        16","page":"3130","citation":{"ieee":"V.

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.</jats:p>"}]},{"status":"public","type":"journal_article","article_number":"107160","_id":"48673","department":[{"_id":"9"},{"_id":"154"},{"_id":"321"}],"user_id":"335","intvolume":"       290","citation":{"chicago":"Lenz, Peter, Phil Kreutzheide, and Rolf Mahnken. “Multiphase Elasto-Plastic Mean-Field Homogenisation and Its Consistent Linearisation.” <i>Computers &#38;amp; Structures</i> 290 (2023). <a href=\"https://doi.org/10.1016/j.compstruc.2023.107160\">https://doi.org/10.1016/j.compstruc.2023.107160</a>.","ieee":"P.

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.</jats:p>"}],"language":[{"iso":"eng"}],"keyword":["Information Systems and Management","Computer Networks and Communications","Modeling and Simulation","Control and Systems Engineering","Software"]},{"status":"public","publication":"Journal of Materials Processing Technology","type":"journal_article","keyword":["Industrial and Manufacturing Engineering","Metals and Alloys","Computer Science Applications","Modeling and Simulation","Ceramics and Composites"],"article_number":"117991","language":[{"iso":"eng"}],"_id":"44078","department":[{"_id":"158"},{"_id":"146"},{"_id":"219"}],"user_id":"43720","year":"2023","intvolume":"       317","citation":{"ieee":"A.

With regard to the examination system, the shift towards output-oriented teaching is still one of the most significant challenges. Assessments have to be integrated into the teaching and learning arrangements and consistently aligned towards the intended learning outcomes. In particular, assessments should provide valid evidence that learners have acquired competences that are relevant for a specific domain. However, it seems that this didactic goal has not yet been fully achieved in modeling education in computer science. The aim of this study is to investigate whether typical task material used in exercises and exams in modeling education at selected German universities covers relevant competences required for graphical modeling. For this purpose, typical tasks in the field of modeling are first identified by means of a content-analytical procedure. Subsequently, it is determined which competence facets relevant for graphical modeling are addressed by the task types. By contrasting a competence model for modeling with the competences addressed by the tasks, a gap was identified between the required competences and the task material analyzed. In particular, the gap analysis shows the neglect of transversal competence facets as well as those related to the analysis and evaluation of models. The result of this paper is a classification of task types for modeling education and a specification of the competence facets addressed by these tasks. Recommendations for developing and assessing student's competences comprehensively are given.","lang":"eng"}],"publication":"Enterprise Modelling and Information Systems Architectures","language":[{"iso":"eng"}],"ddc":["006","000","006"],"keyword":["conceptual modeling","higher education","competence-oriented assessment","task analysis","graphical modeling"],"citation":{"bibtex":"@article{Soyka_Ullrich_Striewe_Schaper_2023, title={Comparison of Required Competences and Task Material in Modeling Education}, volume={18}, DOI={<a href=\"https://doi.org/10.18417/EMISA.18.7\">10.18417/EMISA.18.7</a>}, number={7}, journal={Enterprise Modelling and Information Systems Architectures}, author={Soyka, Chantal and Ullrich, Meike and Striewe, Michael and Schaper, Niclas}, year={2023} }","short":"C.

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.</jats:p>","lang":"eng"}],"status":"public","type":"journal_article","publication":"Chemical Product and Process Modeling"},{"date_created":"2022-05-05T14:05:32Z","author":[{"first_name":"Jörg","orcid":"0000-0001-6141-4571","last_name":"Holtmann","id":"3875","full_name":"Holtmann, Jörg"},{"first_name":"Julien","full_name":"Deantoni, Julien","last_name":"Deantoni"},{"first_name":"Markus","orcid":"0000-0002-1269-0702","last_name":"Fockel","full_name":"Fockel, Markus","id":"8472"}],"publisher":"Springer Science and Business Media LLC","date_updated":"2022-05-05T14:09:41Z","doi":"10.1007/s10270-022-01002-3","title":"Early timing analysis based on scenario requirements and platform models","publication_identifier":{"issn":["1619-1366","1619-1374"]},"publication_status":"published","citation":{"apa":"Holtmann, J., Deantoni, J., &#38; Fockel, M.

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.

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. </jats:p><jats:p> 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.

Competence models in which modeling is integrated at least to some extent already exist in some of these disciplines. However, for the core component of graphical modeling, a competence model that illuminates the relevant competences in detail is still lacking. Therefore, we develop a competence model for graphical modeling with the aim to make teaching and especially assessments in the field more competence-oriented. This paper reports on the first two studies conducted to develop and validate the competence model for graphical modeling. In the first study, the structure of the competence model was developed based on theories and approaches of educational science. Competences relevant for graphical modeling were deductively derived from literature and existing university course descriptions using techniques of qualitative content analysis. The result of the first study is a preliminary competence model. In the second study, the preliminary competence model was reviewed by means of an expert rating in the modeling community. The competence model was revised and refined based on these findings and subsequent expert discussions. The main result of the investigation represents the competence model for graphical modeling (CMGM), which includes a total of 74 competence facets at different cognitive process levels in the five content areas of ”model understanding and interpreting”, ”model building and modifying”, ”values, attitudes, and beliefs”, ”metacognitive knowledge and skills”, and ”social-communicative skills”."}],"publication":"ACM Transactions on Computing Education","type":"journal_article"}]
