Block Copolymer Ordering in Cylindrical Capacitors
No full textWe investigate the morphologies of block copolymers confined in the region between two concentric and charged cylinders. The relative stability of a concentric lamellar phase compared to one where the lamellae are oriented in the radial direction is determined from the competition between long-range elastic and electrostatic forces. We find in weak and strong segregation and by single-chain-in-mean-field simulations that under sufficiently strong voltage difference there is a phase transition from concentric to radial lamellae containing defects. Above a threshold voltage the block copolymer melt develops an interfacial instability at a finite wavelength.German Science Foundation [Mu 1674/11-1

No full textDer schulische Einsatz der digitalen Medien findet bisher zumindest an weiterführenden Schulen vor allem im Computerraum statt. Viele Pädagoginnen und Pädagogen empfinden diese Situation u. a. aufgrund mangelnder Flexibilität und begrenzter Rechnerverfügbarkeit als einschränkend. Theoretisch ließen sich diese Probleme lösen, wenn alle Schülerinnen und Schüler und die Lehrkräfte eigene Computer besäßen, die sie jederzeit nutzen könnten. Einige Schulen (vor allem in den USA und in Großbritannien) haben diesen Schritt bereits getan und die Schülerinnen und Schüler und Lehrkräfte mit Laptops oder Tablet-PCs ausgestattet. Letztere unterscheiden sich von Laptops primär dadurch, dass der Bildschirm auch als Eingabemedium fungiert, das mit einem speziellen Stift oder den Fingern bedient werden kann. In Deutschland basieren mobile Lösungen bisher vor allem auf der Arbeit mit so genannten Laptop-Klassen. Die Ausstattung ganzer Schulen mit solchen Geräten scheiterte bislang u. a. an der Frage der Finanzierung. Mit der zunehmenden Verbreitung von Netbooks scheint sich eine bezahlbare Alternative abzuzeichnen. Vor diesem Hintergrund sowie der insgesamt steigenden Relevanz der Nutzung unterschiedlichster mobiler Endgeräte für Lern- und Bildungsprozesse scheint die Durchdringung der Schule mit allgegenwärtigen bzw. pervasiven digitalen Lerninfrastrukturen nur noch eine Frage der Zeit zu sein (Breiter/Welling 2006; Hug 2010; Holleis et al. 2010).The use of digital media at school, at least at secondary schools, has so far mainly taken place in the computer room. Many educators find this situation restrictive due to a lack of flexibility and limited computer availability, among other things. Theoretically, these problems could be solved if all students and teachers had their own computers that they could use at any time. Some schools (especially in the US and the UK) have already taken this step and equipped students and teachers with laptops or tablet PCs. The latter differ from laptops primarily in that the screen also functions as an input medium that can be operated with a special pen or the fingers. In Germany, mobile solutions have so far been based primarily on work with so-called laptop classes. The equipment of entire schools with such devices has so far failed, among other things, due to the question of financing. With the increasing spread of netbooks, an affordable alternative seems to be emerging. Against this background, as well as the overall increasing relevance of the use of a wide variety of mobile devices for learning and educational processes, the penetration of schools with ubiquitous or pervasive digital learning infrastructures seems to be only a matter of time (Breiter/Welling 2006; Hug 2010; Holleis et al. 2010)
Exporting environment awareness to mobile applications
No full textIn mobile computing, factors such as add-on hardware components and heterogeneous networks result in an environment made up of changing resource constraints. An application in such a constrained environment must react to these changes so that available resources are properly utilized. In this paper, we propose an architecture to report changes in the environment to interested applications. The architecture is based on an event delivery mechanism that decouples event detection from delivery, giving the flexibility and extensibility that is necessary in a mobile computing environment. Information associated with the event is delivered as part of the event notification, while delivery latency is reduced by clever thread scheduling. We demonstrate the utility of our architecture by structuring an environment aware networking subsystem around a prototype implementation. The performance of this implementation is competitive with current event delivery mechanisms such as the Unix signal.Technical report lcsr-tr-27
