With a focus on Technology Enhanced Learning, this paper investigates if and to which extent a culture shift can be expected alongside with the adoption of currently emerging Web 3.0 technologies. Instead of just offering new opportunities for the field to improve education, such a culture shift could lead to unexpected general consequences not just for Technology Enhanced Learning but the whole educational sector. Understanding the dimension of expectable changes enables us to prevent conflicts and pointedly support culture-related change processes. After an introduction of the Revised Onion Model of Culture, which, later on, serves as theoretical foundation, expectable changes in the design of learning scenarios are analysed, distinguishing the stakeholder groups “learners” and “educators”. Eventually, the found changes are analysed to which extent a general culture shift is to be expected in order to understand the transferability and limitations of future research results in the field.
Work in progress: Starter-project for first semester students to survey their engineering studies
(2015)
The steadily decreasing prices of display technologies and computer graphics hardware contribute to the increasing popularity of multiple-display environments, like large, high-resolution displays. It is therefore necessary that educational organizations give the new generation of computer scientists an opportunity to become familiar with this kind of technology. However, there is a lack of tools that allow for getting started easily. Existing frameworks and libraries that provide support for multi-display rendering are often complex in understanding, configuration and extension. This is critical especially in educational context where the time that students have for their projects is limited and quite short. These tools are also rather known and used in research communities only, thus providing less benefit for future non-scientists. In this work we present an extension for the Unity game engine. The extension allows – with a small overhead – for implementation of applications that are apt to run on both single-display and multi-display systems. It takes care of the most common issues in the context of distributed and multi-display rendering like frame, camera and animation synchronization, thus reducing and simplifying the first steps into the topic. In conjunction with Unity, which significantly simplifies the creation of different kinds of virtual environments, the extension affords students to build mock-up virtual reality applications for large, high-resolution displays, and to implement and evaluate new interaction techniques and metaphors and visualization concepts. Unity itself, in our experience, is very popular among computer graphics students and therefore familiar to most of them. It is also often employed in projects of both research institutions and commercial organizations; so learning it will provide students with qualification in high demand.
The Whole Is More than the Sum of Its Parts - On Culture in Education and Educational Culture
(2015)
The Learning Culture Survey investigates learners’ expectations towards and perceptions of education on international level with the aim to make culture in the context of education better understandable and support educators to prevent and solve intercultural conflicts in education. So far, we found that culture-related expectations differ between educational settings, depend on the age of the learners, and that a nationally homogenous educational culture is rather an exception than the rule. The results of our recently completed longitudinal study provided evidence that educational culture on the institutional level actually is persistent, at least over a term of four years. After a brief introduction of the general background, we will subsume the steps taken during the past seven years and achieved general insights regarding educational culture. Last, we will introduce a method for the determination of conflict potential, which bases on the understanding of culture as the level to w hich people within a society accept deviations from the usual. We close with demonstrating the method’s functionality on examples from the Learning Culture Survey.
Gabriel sollte "nein" sagen

The aim of our research is finding measures to preserve the learners’ initial motivation in educational settings. For that we need to avoid conflicting situations that possibly could jeopardize their joy of learning.
In our thematically comprehensive Learning Culture Survey, we investigate the cultural biasing of students’ attitudes, behaviours, and expectations towards education. Particularly in times of massive international migration and growing numbers of refugees, the relevance to deeply understand cultural aspects in education increases. Just with this understanding, we can raise the awareness towards more cultural tolerance across all involved stakeholder groups and thus, foster the development of more culture-sensitive educational approaches. In this paper we focus on the most relevant aspect of motivation and comparatively discuss our study conducted in Germany and South Korea.
Mit unserer Forschung wollen wir Maßnahmen finden, die dazu beitragen, die anfängliche
Bildungsmaßnahmen zu
Motivation von Lernern bewahren. Zu diesem Zweck
in müssen Konfliktsituationen möglichst vermieden werden, wenn sie das Potential haben, ihnen die Freude am Lernen zu verderben. In unserem thematisch breitgefächerten Learning Culture Survey (Untersuchung von Lernkultur), untersuchen wir bei Lernern das Vorhandensein und den Einfluss kulturspezifischer Prägungen auf deren Verhaltensweisen, Gewohnheiten und Erwartungen bzgl. Bildung. Besonders in Zeiten massiver internationaler Migration und steigender Zahlen von Flüchtlingen wächst der Bedarf nach entsprechender Forschung stetig an. Nur wenn wir die Zusammenhänge zwischen Lernen und Kultur ausreichend verstehen, sind wir in der Lage, auf allen Ebenen die Entwicklung des erforderlichen Bewusstseins bzgl. kultursensibler Bildungsansätze zu fördern. In diesem Beitrag konzentrieren wir uns auf den sehr wichtigen Aspekt Motivation und diskutieren die Ergebnisse, die wir in unserer vergleichenden Studie in Deutschland und Südkorea erzielt haben.

Quality Management in Education: Business Process Modelling in Interdisciplinary Environments
(2015)
Der Einsatz von Agentensystemen ist vielfältig, dennoch sind aktuelle Realisierungen lediglich in der Lage primär regelkonformes oder aber „geskriptetes“ Verhalten auch unter Einsatz von randomisierten Verfahren abzubilden. Für eine realistische Repräsentation sind jedoch auch Abweichungen von den Regeln notwendig, die nicht zufällig sondern kontextbedingt auftreten. Im Rahmen dieses Forschungsprojektes wurde ein realitätsnaher Straßenverkehrssimulator realisiert, der mittels eines detailliert definierten Systems für kognitive Agenten auch diese irregulären Verhaltensweisen generiert und somit ein realistisches Verkehrsverhalten für die Verwendung in VR-Anwendungen simuliert. Durch das Erweitern der Agenten mit psychologischen Persönlichkeitsprofilen, basierend auf dem „Fünf-Faktoren-Modell“, zeigen die Agenten individualisierte und gleichzeitig konsistente Verhaltensmuster. Ein dynamisches Emotionsmodell sorgt zusätzlich für eine situationsbedingte Adaption des Verhaltens, z.B. bei langen Wartezeiten. Da die detaillierte Simulation kognitiver Prozesse, der Persönlichkeitseinflüsse und der emotionalen Zustände erhebliche Rechenleistungen verlangt, wurde ein mehrschichtiger Simulationsansatz entwickelt, der es erlaubt den Detailgrad der Berechnung und Darstellung jedes Agenten während der Simulation stufenweise zu verändern, so dass alle im System befindlichen Agenten konsistent simuliert werden können. Im Rahmen diverser Evaluierungsiterationen in einer bestehenden VR-Anwendung – dem FIVIS-Fahrradfahrsimulator des Antragstellers - konnte eindrucksvoll nachgewiesen werden, dass die realisierten Konzepte die ursprünglich formulierten Forschungsfragestellung überzeugend und effizient lösen.
The proper use of protective hoods on panel saws should reliably prevent severe injuries from (hand) contact with the blade or material kickbacks. It also should minimize long-term lung damages from fine-particle pollution. To achieve both purposes the hood must be adjusted properly by the operator for each workpiece to fit its height. After a work process is finished, the hood must be lowered down completely to the bench. Unfortunately, in practice the protective hood is fixed at a high position for most of the work time and herein loses its safety features. A system for an automatic height adjustment of the hood would increase comfort and safety. If the system can distinguish between workpieces and skin reliably, it furthermore will reduce occupational hazards for panel saw users. A functional demonstrator of such a system has been designed and implemented to show the feasibility of this approach. A specific optical sensor system is used to observe a point on the extended cut axis in front of the blade. The sensor determines the surface material reliably and measures the distance to the workpiece surface simultaneously. If the distance changes because of a workpiece fed to the machine, the control unit will set the motor-adjusted hood to the correct height. If the sensor detects skin, the hood will not be moved. In addition a camera observes the area under the hood. If there are no workpieces or offcuts left under the hood, it will be lowered back to the default position.

Solar energy is one option to serve the rising global energy demand with low environmental Impact [1]. Building an energy system with a considerable share of solar power requires long-term investment and a careful investigation of potential sites. Therefore, understanding the impacts from varying regionally and locally determined meteorological conditions on solar energy production will influence energy yield projections. Clouds are moving on a short term timescale and have a high influence on the available solar radiation, as they absorb, reflect and scatter parts of the incoming light [2]. However, modeling photovoltaic (PV) power yields with a spectral resolution and local cloud information gives new insights on the atmospheric impact on solar energy.
Semantic Image Segmentation Combining Visible and Near-Infrared Channels with Depth Information
(2015)
Image understanding is a vital task in computer vision that has many applications in areas such as robotics, surveillance and the automobile industry. An important precondition for image understanding is semantic image segmentation, i.e. the correct labeling of every image pixel with its corresponding object name or class. This thesis proposes a machine learning approach for semantic image segmentation that uses images from a multi-modal camera rig. It demonstrates that semantic segmentation can be improved by combining different image types as inputs to a convolutional neural network (CNN), when compared to a single-image approach. In this work a multi-channel near-infrared (NIR) image, an RGB image and a depth map are used. The detection of people is further improved by using a skin image that indicates the presence of human skin in the scene and is computed based on NIR information. It is also shown that segmentation accuracy can be enhanced by using a class voting method based on a superpixel pre-segmentation. Models are trained for 10-class, 3-class and binary classification tasks using an original dataset. Compared to the NIR-only approach, average class accuracy is increased by 7% for 10-class, and by 22% for 3-class classification, reaching a total of 48% and 70% accuracy, respectively. The binary classification task, which focuses on the detection of people, achieves a classification accuracy of 95% and true positive rate of 66%. The report at hand describes the proposed approach and the encountered challenges and shows that a CNN can successfully learn and combine features from multi-modal image sets and use them to predict scene labeling.

Viele Controller verzeichnen steigende IT-Kosten, die zum Teil durch Lizenzkosten verursacht werden. Oft werden Kosteneinsparungen durch ineffizientes oder fehlendes Lizenzmanagement nicht realisiert, zudem sehen sich zahlreiche Unternehmen zusehends mit dem Problem nicht budgetierter Nachlizenzierungen, aufgrund steigender Aktivitäten der Softwarehersteller im Bereich der Lizenzierungsüberprüfung, konfrontiert. Der Beitrag zeigt die Problematik des IT-Lizenzmanagements und grundsätzliche Lösungsmöglichkeiten auf. Ein Referenzmodell demonstriert, wie im praktischen Anwendungsfall eine Kostensenkung und Prozessverbesserung realisiert werden kann.

Duale Studiengänge liegen einerseits stark im Trend, andererseits funktioniert die Abstimmung zwischen Hochschulstudium und Praxisphasen oftmals nicht. Obwohl eine Lernortkooperation zwischen »Praxis« und »Hochschule« das Engagement beider Seiten erfordert, wird in einem Projekt der Hochschule Bonn-Rhein-Sieg, der Deutschen Gesetzlichen Unfallversicherung (DGUV) und des BIBB zunächst erprobt, wie das Verständnis der Praxisbetreuer/-innen für Studierende und Studium verbessert werden kann. Hierzu werden im Beitrag Konzeption und Zielsetzung eines zweitägigen Seminars bei der Akademie der DGUV vorgestellt und erste Erfahrungen geschildert.

IT-accessiblity is often treated as an orphan in companies. Even though the proportion of disabled people is substantial and people become older and more susceptible to disabilities. Besides cost factors, companies often do not have a plan how to implement and control IT-accessibility successfully. However, most companies are familiar with IT-maturity frameworks to evaluate and improve their own IT-infrastructure. It would facilitate dealing with IT-accessibility, if IT-maturity frameworks consider IT-accessibility and provide recommendations and solutions for a successful implementation. Therefore, this article conducts a review of an acknowledged IT-maturity framework with regard to its capability to enable implementation of IT-accessibility in an organization. The first part of this article will illustrate the motivation and background for the authors concern with such a topic. Afterwards the authors will introduce the reader to the reviewed IT-maturity framework and provide basic knowledge on IT-accessibility. The main part of the article will deal with the review of the applied IT-maturity framework and outline examples of critical capabilities for successfully implementing IT-accessibility in an organization. The final section will derive implications and close with planned future research activities in this field.
