Learning the German language is one of the most critical challenges for refugee children in Germany. It is a prerequisite to allow communication and integration into the educational system. To solve the underlying problem, we conceptualized a set of principles for the design of language learning systems to support collaboration between teachers and refugee children, using a Design Science Research approach. The proposed design principles offer functional and non-functional requirements of systems, including the integration of open educational resources, different media types to develop visual and audio narratives that can be linked to the cultural and social background. This study also illustrates the use of the proposed design principles by providing a working prototype of a learning system. In this, refugee children can learn the language collaboratively and with freely accessible learning resources. Furthermore, we discuss the proposed design principles with various socio-technical aspects of the well-being determinants to promote a positive system design for different cultural and generational settings. Overall, despite some limitations, the implemented design principles can optimize the potential of open educational resources for the research context and derive further recommendations for further research.
Das Ziel der vorliegenden Bachelorarbeit ist die Konzeption eines neuen Ansatzes − die Positive Co-Creation −, der die Elemente des Positive Computing in die Co-Creation integriert. Dafür wurden in einer Literaturanalyse die bestehenden Schwachstellen der Co-Creation herausgearbeitet, um anschließend die Vorteile des Positive Computing aufzuzeigen. Nach der Entwicklung eines spezifischen Modells der Positive Co-Creation, inklusive der verwendeten Methoden und deren Auswirkungen auf die Wohlbefindensfaktoren, wurde das Modell anhand von Experteninterviews evaluiert und verbessert. Das Ergebnis dieser Arbeit ist ein theoretisches Modell der Positive Co-Creation, welches den Prozess vollständig abbildet und einen Ansatzpunkt für eine praktische Umsetzung bildet. Dieser Ansatz ist gut geeignet, um bestehende Co-Creation-Prozesse anhand von Technologien um die Aspekte des Wohlbefindens zu erweitern.
The task of object detection in the automotive sector can be performed by evaluating various
sensor data. The evaluation of LiDAR data for the detection of objects is a special challenge for
which systems with neural networks can be used. These neural networks are trained by means of a
data set. If you want to use the net with your own recordings or another data set, it is important
to know how well these systems work in combination with data from another sensor. This allows
the results to be estimated in advance and compared with the results of previous experiments.
In this work the sensor dependence of a LiDAR based object recognition with neural networks
will be analysed. The detector used in this work is PointRCNN [1], which was designed for the
KITTI dataset [2]. To check the sensor dependency, the ’AEV Autonomous Driving Dataset’
(A2D2) dataset [3] was selected as a further dataset. After an introduction to PointRCNN and its
functionality, the data of both datasets are analysed. Then the data of the second dataset will be
ported into the format of the KITTI dataset so that they can be used with PointRCNN. Through
experiments with varying combinations of training and validation data it shall be investigated to
what extent trained models can be transferred to other sensor data or datasets. Therefore, it shall
be investigated how strong the dependence of the detector (PointRCNN) on the used sensors is.
The results show that PointRCNN can be evaluated with a different dataset than the training
dataset while still being able to detect objects. The point density of the datasets plays a decisive
role for the quality of the detection. Therefore it can be said that PointRCNN has a sensor
dependency that varies with the nature of the point cloud and its density.

Das Ziel der vorliegenden Arbeit ist es, die Eignung von MeshLab in einem Reverse-Engineering-Projekt zu überprüfen. Dazu wurden vor Beginn sechs Kriterien aufgestellt, auf die MeshLab untersucht wird. Das Ergebnis zeigt, dass MeshLab fünf von sechs Kriterien erfüllt und somit für einen Einsatz geeignet ist.
MeshLab ist ein Teil der Datenaufbereitung des Reverse Engineering. Es ist ein kostenloses Programm und somit in Kombination mit einem günstigen Scanner für einen Einsatz in Reverse-Engineering-Projekten mit einem geringen Kostenaufwand einsetzbar.
The aim of this bachelor thesis is to verify the suitability of MeshLab in a Reverse-Engineering-Project. Before the beginning six criterias were set up on which MeshLab is examined. The result shows that MeshLab fulfills five of six criterias and is therefore suitable for use.
MeshLab is a part of the data preparation from the Reverse Engineering. It is a free programm and in combination with a cheap scanner, it can be used in a Revere-Engineering-Project with a low Budget.
Die Möglichkeiten der Wissensvermittlung über eingebettete Systeme haben sich durch das erforderliche distance learning stark verändert. Die bekannten didaktischen Konzepte, welche bis dahin angewandt wurden, werden durch den Wegfall von Präsenz-Praktika und den fehlenden Zugang zu einem IoT- Labor ausgehebelt.
Diese Master-Thesis beschäftigt sich daher mit der Idee, wie eine Überholung des Eingebettete Systeme-Moduls an der Hochschule Ruhr West sowohl die Modulziele weiter erfüllen kann als auch darüber hinaus einen Mehrwert erschaffen wird. Vor diesem Hintergrund wird untersucht wie durch die Einführung eines Remote-Labs in Kombination mit einer kollaborativen Entwicklungssoftware für Lerngruppen, Anreize für die Studierenden geschaffen werden können, die ihnen praxisnäheres und fundiertes Wissen in der Entwicklung eingebetteter Systeme vermitteln.
Dieses neue Vorgehen verwendet einen Peer-Group-Code-Bearbeitung- Ansatz in Echtzeit und Peer-to-Peer-Videokonferenzen und verteilt über den MQTT-Server die Interaktion der Hardwareentwicklung als integralen Bestandteil eines Kurskonzepts. Ziel ist es, die Motivation und die Lernleistung der Schüler zu verbessern.
Das Vorgehen wird anhand begleitender Umfragen während des Moduls weiterentwickelt und die Semesterergebnisse werden unter Zuhilfenahme von Bewertungskriterien mit denen vergangener Jahre verglichen. Darüber hinaus wird das neue Kurskonzept durch eine Expertenbefragung in Form von Studierenden evaluiert, welche den Kurs in seiner alten Form durchlaufen haben.

So far, researchers have used a wellbeing-centered approach to catalyze successful intergenerational collaboration (IGC) in innovative activities. However, due to the subject’s multidisciplinary nature, there is still a dearth of comprehensive research devoted to constructing the IGC system. Thus, the purpose of this study is to fill a research void by providing a conceptual framework for information technology (IT) system designers to use as a jumping-off point for designing an IGC system with a wellbeing-oriented design. A systematic literature study was conducted to identify relevant terms and develop a conceptual framework based on a review of 75 selected scientific papers. The result consists of prominent thematic linkages and a conceptual framework related to design technology for IGC systems. The conceptual framework provides a comprehensive overview of IGC systems in the innovation process by identifying five barrier dimensions and using six wellbeing determinants as IGC catalysts. Moreover, this study discusses future directions for research on IGC systems. This study offers a novel contribution by shifting the technology design process from an age-based design approach to wellbeing-driven IGC systems. Additional avenues for investigation were revealed through the analysis of the study’s findings.
This study proposes a framework for the collaborative development of global start-up innovators in a multigenerational digital environment. Intergenerational collaboration has been identified as a strategy to support entrepreneurs during their formative years. However, integrating and fostering intergenerational collaboration remains elusive. Therefore, this study aims to identify competencies for successful global start- ups through intergenerational knowledge transfer. We used a systematic literature review to identify a competency set consisting of growth virtues, effectual creativity, technical domain, responsive teamwork, values-based organization, sustainable networking, cultural awareness, and facilitating intergenerational safety. The competency framework serves as a foundation for knowledge management research on the global innovation readiness of people to collaborate across generations in the digital age.
This study aims to determine the competing concerns of people interested in startup development and entrepreneurship by using topic modeling and sentiment analysis on a social question-and-answer (SQA) website. Understanding the underlying concerns of startup entrepreneurs is critical to society and economic growth. Therefore, greater scientific support for entrepreneurship remains necessary, including data mining from virtual social communities. In this study, an SQA platform was used to identify the sentiment of thirty concerns of people interested in startup entrepreneurship. Based on topic modeling and sentiment analysis of 18819 inquiries in various forums on an SQA, we identified additional questions about founder figures, keys to success, and the location of a startup. In addition, we found that general questions were rated more positively, especially when it came to pitching, finding good sources, disruptive innovation, idea generation, and marketing advice. On average, the identified concerns were considered 48.9 percent positive, 41 percent neutral, and 10.1 percent negative. This research establishes a critical foundation for future research and development of digital startups by outlining a variety of different concerns associated with startup development in the digital age.
Ziel dieser Arbeit ist es, eine deutlich definierte Markenidentität für DigiCerts zu konzipieren. Zu diesem Zweck wird das Markensteuerrad von Esch (2018, S.98) angewandt, um in detaillierten Schritten eine nützliche Markenidentität aufzubauen. Mithilfe dieser soll anschließend folgende Fragestellung beantwortet werden: Wie kann sich DigiCerts in der Hochschullandschaft positionieren? Zur Beantwortung der zugrunde liegenden Frage, wird die Positionierungspyramide von Esch(2009, S. 163)genutzt.
Insgesamt soll mithilfe dieser Arbeit eine für DigiCerts anwendbare Identität aufgebaut werden.
