text: Schneijderberg und Steinhardt zeichnen in diesem Beitrag nach, wie
Akkreditierung als sanftes Konditionalprogramm in Bezug auf Diversity-Dimensionen
gewirkt hat. Unter sanfter Konditionierung wird in Anlehnung an Luhmann die politische
Steuerung durch Akkreditierungskriterien verstanden, die als Vehikel genutzt werden,
um gesellschaftlich aktuell diskutierte Themen in den Hochschulen zu platzieren.
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. Um die Konditionierung nachzuzeichnen, wurde in
einem zweiten Schritt eine Topic-Modeling-Analyse von 828 Selbstdokumentationen
der Hochschulen, 743 Gutachtenberichte und 560 Beschlussbriefen durchgeführt.

text: Most single-screw extruders used in the plastics processing industry are plasticizing
extruders, designed to melt solid pellets or powders within the screw channel
during processing. 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.

text: The introduction of Systems Engineering is an approach for dealing
with the increasing complexity of products and their associated product development.
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.

text: As a simplified version of a three-component taxis cascade model
accounting for different migration strategies of two population groups in search
of food, a two-component nonlocal nutrient taxis system is considered in a two-dimensional
bounded convex domain with smooth boundary. For any given conveniently regular
and biologically meaningful initial data, smallness conditions on the prescribed
resource growth and on the initial nutrient signal concentration are identified
which ensure the global existence of a global classical solution to the corresponding
no-flux initial-boundary value problem. Moreover, under additional assumptions
on the food production source these solutions are shown to be bounded, and to
stabilize toward semi-trivial equilibria in the large time limit, respectively.

text: 'The success of engineering complex technical systems is determined
by meeting customer requirements and institutional regulations. 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.'

text: The reform of the European academic landscape with the introduction of bachelor's
and master's degree programs has brought about several profound changes for teaching
and assessment in higher education. 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.

text: "Abstract\r\n Sandwich packings
represent new separation column internals, with a potential to intensify mass
transfer. 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."

text: Distributed, software-intensive systems (e.g., in the automotive sector) must
fulfill communication requirements under hard real-time constraints. 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.

text: ' We introduce a new phase field model for tumor growth where viscoelastic
effects are taken into account. 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]. '

text: Modeling is an integral part of many computing-related disciplines and thus
also represents a curricular core component in computing education in tertiary
education. 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”.
