The developed solution enables the presentation of animations and 3D virtual reality (VR) on mobile devices and is well suited for mobile learning, thus creating new possibilities in the area of e-learning worldwide. Difficult relations in physics as well as intricate experiments in optics can be visualised on mobile devices without need for a personal computer.
The University for Children is a very successful event aiming to spark children‧s interest in science, in this particular lecture in Optics and Photonics. It is from brain research that we know about the significant dependence of successful learning on the fun factor. Researchers in this field have shown that knowledge acquired with fun is stored for a longer time in the long-term memory and can be used both more efficiently and more creatively [1], [2]. Such an opportunity to inspire the young generation for science must not be wasted. The world of Photonics and Optics provides us with a nearly inexhaustible source of opportunities of this kind.
"Live aus Nogaro" oder "Ein bisschen Formel 1 für Studenten." Nun ja, nicht ganz: Bei der Formel 1 verbraucht ein Rennstall ca 200.000 Liter benzin pro Saison, bei dem Rennen in Nogaro jeoch steht genau ein Liter Sprit zur Verfügung. Und noch etwas unterscheidet die beiden Wettbewerbe: In der Formel 1 gibt es keine Vorschrift für die Mindestgeschwindigkeit, im Gegensatz zum Shell Eco-Marathon, wo eine Mindestgeschwindigkeit von 30 km/h vorgeschrieben ist. In diesem Jahr kam das Rennfeeling durch die Live-Übertragung des Rennens im Internet noch besser an. Eine Gruppe von 16 Studenten aus verschiedenen Semestern der Fakultät Medien- und Informationswesen zusammen mit sechs Betreuern und wissenschaftlichen Mitarbeitern der Fakultät Medien- und Informationswesen hatten sich als Ziel gesetzt, dieses Ereignis live und - in Anbetracht der Beteiligung der Hochschule am Rennen - möglichst neutral ins Internet zu senden.
Recent developments in information and communication technology, along with advanced displaying techniques and high computational performance open up new visualisation methods to both scientists and lecturers. Thus simulations of complex processes [1] can be computed and visualised in image sequences. The particular idea in our approach is the outsourcing of computationally intensive calculations to servers which then send the results back to mobile users. In order to improve interpretations of the visualised results, users can view them in a 3D-perspective or stereoscopically, given the technical requirements. Today’s technology even permits to view these visualisations on a mobile phone. An example for such a computationally intensive calculation originating from the theory of relativity is depicted in Figure 4.1-1.
In short-reach connections, large-diameter multimode fibres allow for robust and easy connections. Unfortunately, their propagation properties depend on the excitation conditions. We propose a launching technique using a fibre stub that can tolerate fabrication tolerances in terms of tilts and off-sets to a large extent. A study of the influence of displaced connectors along the transmission link shows that the power distributions approach a steady-state power distribution very similar to the initial distribution established by the proposed launching scheme.
