Der Rückblick zum TEWI-Kolloquium von Prof. Dr. Benjamin Rott am 8. November 2018 beinhaltet das Video und Vortragsfolien (siehe unten):

Kurzfassung:
In der Mathematikdidaktik wird das Problemlösen seit Pólyas „Schule des Denkens“ – mal mehr und mal weniger intensiv – thematisiert. Im Vortrag werden wichtige Ergebnisse entsprechender Forschung resümiert und es werden an konkreten Beispielen aktuelle Forschungsprojekte aus Deutschland erläutert, in denen es u. a. um Heurismen, ihre Wirksamkeit und Lehrbarkeit sowie um Problemlösen im Mathematikunterricht und in der Lehrerbildung geht.

Abschließend wird aus Sicht des Vortragenden beschrieben, wie nächste Schritte auf dem Gebiet der Problemlöseforschung aussehen könnten und sollten.

CV:

Review: On-the-fly Collaboration for Legacy Business Process Systems in An Open Service Environment [Slides]

The review of the TEWI colloquium of Prof. Liang ZHANG (Leon) Ph.D from July 5, 2019 comprises the slides (below):

Abstract:

Dynamic, distributed and open business forces enterprises to support various critical requirements, such as, timely reacting to changes, properly reusing business assets and smoothly collaborating with external partners. Existing approaches focus on mechanisms dealing with heterogeneity, but there is a lack of frameworks enabling legacy business processes performing collaboration in an open service environment. This paper proposes the L2L service framework featuring reactive IoT event messaging and coordinator-based collaborating between autonomous enterprises. Along with the emerging of coordinators, L2L empowers on-the-fly business process collaboration with dynamic changes. We present our experiments with a real-world scenario from the shipping industry of China.

Review: Teaching about AR and Teaching with AR [Slides][Video]

The review of the TEWI colloquium of PD Dr. Ralf Klamma from June 17, 2019 comprises the video and slides (below):

Abstract:

Augmented Reality (AR) is on the way to establishing itself in business and teaching once more. However, there is a lack of uniform guidelines or even standards both in the creation of teaching materials and in the use of AR in teaching. In addition, the industry needs enough well-trained specialists who can implement the established AR concepts, making a transfer from university to industry necessary. Therefore, in this talk we address both challenges in teaching with AR and the special needs of teaching about AR.

As teaching with AR will surely advance human performance and also brings in new perspectives with the communication, coordination and collaboration of AR in supporting human performance. As computer scientists, we have a European, interdisciplinary and application-oriented perspective, as our experience comes from several funded European projects in these areas. We also incorporate new incentives into teaching contexts in our framework, such as gamification, learning analytics and experience capturing. In addition, we refer to international standardization efforts such as IEEE ARLEM.

Teaching about AR adopts a multi-perspective view. First, there is scientific and technological basic knowledge helping to understand the underlying physical and technical principles. Second, there is engineering and design knowledge to master the creation, fabrication, and utilization of AR in many ways. Third, there is the necessary pedagogical knowledge to transform these complex settings in manageable teaching scenarios and processes, e.g. for higher education curricula.

Here, teaching AR can learn from traditions of science and engineering education as well as from more recent knowledge about computer science education. Examples from recent and on-going European projects will illustrate the argumentation.

Swarm Robotics – A Formal Approach

Prof. Dr.-Ing. Heiko Hamann | July 8, 2019 | 15:00 | B02.2.05

Abstract:
In similar style to the book of the same title we try to understand how to design large-scale robot systems by going through several example scenarios on topics such as aggregation, task allocation, self-assembly, collective decision-making, and collective construction. We study the methodology behind building multiple, simple robots and how the complexity emerges from multiple interactions between these robots such that they are able to solve difficult tasks.

CV:
Heiko Hamann received his doctorate in engineering from the University of Karlsruhe, Germany in 2008. He did his postdoctoral training in modular robotics and evolutionary robotics at the Zoology department of the University of Graz, Austria. From 2013 to 2017 he was assistant professor of swarm robotics at the University of Paderborn, Germany. Since 2017 he is full professor for service robotics at the University of Lübeck, Germany. His main research interests are swarm robotics, evolutionary robotics, and modeling of complex systems.

MEMS microfabrication-part 2: Back-end

Dr. Ali Roshanghias | June 25, 2019 | 10:30 | B04.1.06

Abstract:

In this talk, the back-end processing and integration technologies of MEMS devices will be addressed. Unlike electronics IC packaging, MEMS packaging in not well-established, is expensive (up to 80% of the product total cost and is custom-built. Here, we will introduce the basics of MEMS packaging in different levels of integrations. The common backend processes will be covered in this talk such as wafer dicing, wafer thinning, wafer bonding, molding and over-molding, die-attach, solder bumping and wire bonding, etc. We will also briefly introduce the state of the art and future trends of MEMS packaging and some terminologies such as 3D integration with and without TSVs, FOLWP, C2C, C2W, W2W, SiP, SiB, for MEMS integration will be described.
