abstract = {{Excellent Information Systems (IS) bachelor or master student theses have the potential to inform the
scientific community about interesting findings about IS phenomena. However, transforming such
theses into scientific working papers is not only time-consuming for the student and the supervisor, but
also purely voluntary. Part of the problem is that few IS faculties offer any structured course for the
transformation process as part of their curriculum. This significantly reduces the proportion of
outstanding theses that are developed into working papers and, ultimately, into publications, resulting
in a loss of knowledge for the broader IS community. To address this structural deficit, we aim to
develop and implement a credit course and open educational resources (e.g., course schedule, slides,
videos) that support students in developing their theses into publishable scientific research papers. This
approach not only enriches the scientific discourse but also presents a research-oriented educational
disruption for the IS community.}},

The model fit (χ2/df=1.284; RMSEA=0.051; CFI=0.948; SRMR=0.061) and the internal consistency of the scales can be rated as good.

abstract = {{ Lightweight design by using low-density and load-adapted materials can reduce the weight of vehicles and the emissions generated during operation. However, the usage of different materials requires innovative joining technologies with increased versatility. In this investigation, the focus is on describing and characterising the failure behaviour of connections manufactured by an innovative thermomechanical joining process with adaptable auxiliary joining elements in single-lap tensile-shear tests. In order to analyse the failure development in detail, the specimens are investigated using in-situ computed tomography (in-situ CT). Here, the tensile-shear test is interrupted at points of interest and CT scans are conducted under load. In addition, the interrupted in-situ testing procedure is validated by comparing the loading behaviour with conventional continuous tensile-shear tests. The results of the in-situ investigations of joints with varying material combinations clearly describe the cause of failure, allowing conclusions towards an improved joint design. }},

abstract = {{This paper deals with the modeling of a soft sensor for detecting α’-martensite evolution from the micromagnetic signals that are measured during the reverse flow forming of metastable AISI 304L austenitic steel. This model can be prospectively used inside a closed-loop property-controlled flow forming process. To achieve this, optimization by means of a non-linear regression of experimental data was carried out. To collect the experimental data, specimens were produced by flow forming seamless tubes at room temperature. Using a combination of production parameters (like the infeed depth and feed rate), specimens with different α’-martensite contents and wall-thickness reductions were produced. An equation to compute α’-martensite from both specific production-process parameters and micromagnetic Barkhausen noise (MBN) measurements was obtained using numerical methods. In this process, the behavior of the quantity of interest (namely, the α’-martensite content) was mathematically evaluated with respect to non-destructive MBN data and the feed rate that was used to produce the components. A combination of exponential and potential functions was defined as the ansatz functions of the model. The obtained model was validated online and offline during the real flow forming of workpieces, obtaining average deviations of up to 7% α’-martensite with respect to the model. The implementation of the soft sensor model for property-controlled production represents an important milestone for producing high-added-value components on the basis of a well-understood process-microstructure-property relationship.}},

abstract = {{This paper deals with micromagnetic measurements for online detection of
strain-induced α’-martensite during plastic deformation of metastable
austenitic steel AISI 304L. The operating principles of the sensors are
Barkhausen noise (MBN) and eddy currents (EC), which are suitable for
detection of microstructure evolution due to formation of ferromagnetic
phases. Nevertheless, the description of the calibration and
transformation models of the micromagnetic measurements into
quantitative α’-martensite fractions is beyond the scope of this paper.
The focus will be put on the qualification of different micromagnetic
methods as well as of different measurement systems under conditions
similar to the real ones during production, which is crucial for
implementation of a property-controlled flow forming process. The
investigation was carried out on tubular specimens produced by flow
forming, which have different content of α’-martensite. To characterize
the sensitivity of the sensors, different contact conditions between
sensors and workpieces were reproduced. MBN sensors are suitable for
detecting amount of α’-martensite, but the measurements are affected by
the surface roughness. This entails that the calibration models for MBN
sensors must take account of these effects. EC sensors show a closer
match with the amount of α’-martensite without having major affectation
by other effects.}},
