E‐Learning is a concept which has been known for a number of years. It was firstly promoted enthusiastically and then quietly came to a halt when the unrealistic expectations set could not be fulfilled. However, it can be a very useful tool when used in the right context and in combination with traditional learning methods. This is demonstrated in this study, where an E‐Learning tool was designed as a universal exercise software tool, developed to support the learning and training phase of students in lectures on household technologies, and evaluated on a specific course at the University of Bonn. The tool itself – called ItkA – proves on the one hand to be well suited to encouraging students to do additional self‐study and on the other hand is simple enough to allow lecturers with little or no experience of E‐Learning tools to implement the specific knowledge of a lecture.
This English edition could serve as a text for a first year graduate course on differential geometry, as did for a long time the Chicago Notes of Chern mentioned in the Preface to the German Edition. Suitable references for ordin ary differential equations are Hurewicz, W. Lectures on ordinary differential equations. MIT Press, Cambridge, Mass., 1958, and for the topology of surfaces: Massey, Algebraic Topology, Springer-Verlag, New York, 1977. Upon David Hoffman fell the difficult task of transforming the tightly constructed German text into one which would mesh well with the more relaxed format of the Graduate Texts in Mathematics series. There are some e1aborations and several new figures have been added. I trust that the merits of the German edition have survived whereas at the same time the efforts of David helped to elucidate the general conception of the Course where we tried to put Geometry before Formalism without giving up mathematical rigour. 1 wish to thank David for his work and his enthusiasm during the whole period of our collaboration. At the same time I would like to commend the editors of Springer-Verlag for their patience and good advice.

This book presents the majority of the contributions to the Tenth German-Vietnamese Seminar on Physics and Engineering (GVS10) that took place in the Gustav- Stresemann-Institut (GSI) in Bonn from June 6 to June 9, 2007. In the focus of these studies are the preparation and basic properties of new material systems, related investigation methods, and practical applications. Accordingly the sections in this book are entitled electrons: transport and confinement, low-dimensional systems, magnetism, oxidic materials, organic films, new materials, and methods. The series of German-Vietnamese seminars was initiated and sponsored by the Gottlieb Daimler- and Karl Benz -Foundation since 1998 and took place alt- nately in both countries. These bilateral meetings brought together top-notch senior and junior Vietnamese scientists with German Scientists and stimulated many contacts and co-operations. Under the general title "Physics and Engine- ing" the programs covered, in the form of keynote-lectures, oral presentations and posters, experimental and theoretical cutting-edge material-physics oriented topics. The majority of the contributions was dealing with modern topics of material science, particularly nanoscience, which is a research field of high importance also in Vietnam. Modern material science allows a quick transfer of research results to technical applications, which is very useful for fast developing countries like Vietnam. On the other hand, the seminars took profit from the strong cro- fertilization of the different disciplines of physics. This book is dedicated to the tenth anniversary of the seminars and nicely shows the scientific progress in Vietnam and the competitive level reached.
In February 2006, more than 30 leading scholars in Japanese Studies gathered at Bonn University to discuss various facets of the current state of this field and its future directions. The lectures and discussions have been assembled in a proceedings volume, which opens with a paper on the character of modernization in Japanese society based on the keynote lecture by R.P. Dore, the doyen of Japanese social studies. This volume also features papers on anthropology, Ryukyuan and Ainu studies, and the perception of Japan and Japanese culture by the West as reflected in various fields of study. The dominant theme running through the contributions is the methodological and theoretical evaluation of different approaches and the validity of their results. These papers delineate the major directions in which Japanese Studies must proceed in order to fulfill their mission of furthering intercultural communication by interpreting Japanese culture and society.
These are the proceedings of the 8th European Conference on Symbolic and Quantitative Approaches to Reasoning with Uncertainty, ECSQARU 2005, held in Barcelona (Spain), July 6–8, 2005. The ECSQARU conferences are biennial and have become a major forum for advances in the theory and practice of r- soning under uncertainty. The ?rst ECSQARU conference was held in Marseille (1991), and after in Granada (1993), Fribourg (1995), Bonn (1997), London (1999), Toulouse (2001) and Aalborg (2003). The papers gathered in this volume were selected out of 130 submissions, after a strict review process by the members of the Program Committee, to be presented at ECSQARU 2005. In addition, the conference included invited lectures by three outstanding researchers in the area, Seraf´ ?n Moral (Imprecise Probabilities), Rudolf Kruse (Graphical Models in Planning) and J´ erˆ ome Lang (Social Choice). Moreover, the application of uncertainty models to real-world problems was addressed at ECSQARU 2005 by a special session devoted to s- cessful industrial applications, organized by Rudolf Kruse. Both invited lectures and papers of the special session contribute to this volume. On the whole, the programme of the conference provided a broad, rich and up-to-date perspective of the current high-level research in the area which is re?ected in the contents of this volume. IwouldliketowarmlythankthemembersoftheProgramCommitteeandthe additional referees for their valuable work, the invited speakers and the invited session organizer.
The VI. International Workshop on Physics of Nonideal Plasmas (PNP VI) took place from November 18th to 21th, 1991, in Gosen (Germany) at the Science communication & Conference Centre of the Humboldt University of Berlin. The workshop was organized by the Institute for Theoretical Physics of the Humboldt University and by the Central Institute of Electron Physics, Berlin, with financial support given by the Deutsche Forschungsgemeinschaft, Bonn, and the Robert-Bosch-Stiftung, Stuttgart. The workshop was attended by more than 100 scientists from 14 countries who presented about 120 papers, including 18 invited lectures. The series of PNP workshops, which started in 1980, provides a biennial forum for both experimental and theoretical research in the field of nonideal plasmas. These meetings are organized alternately by the Central Institute of Electron Physics, Berlin, and/or by one of the universities of Berlin, Greifswald, and Rostock. They took place in Matzlow-Garwitz (1980), Wustrow (1982 and 1988), Biesenthal (1984), and Greifswald (1986). Since the beginning, the workshop has been concerned mainly with fundamental studies of the thermodynamic, transport, and radiative properties of nonideal plasmas. These fields were also covered at PNP VI in Gosen, but new topics such as high-pressure laser plasmas, dense astrophysical plasmas, molecular dynamics and Monte-Carlo results, and the kinetics of transitions have completed the programme. In particular, several papers addressed the role of nonideal plasmas for radiation sources, for inertial confinement fusion, for helio-seismology, and for the determination of the structure of the giant planets.
Overthelastdecades,energyminimizationmethods havebecomeanestablished paradigm to resolve a variety of challenges in the ?elds of computer vision and pattern recognition. While traditional approaches to computer vision were often based on a heuristic sequence of processing steps and merely allowed very l- ited theoretical understanding of the respective methods, most state-of-the-art methods are nowadays based on the concept of computing solutions to a given problem by minimizing respective energies. This volume contains the papers presented at the 7th International Conf- ence on Energy Minimization Methods in Computer Vision and Pattern Rec- nition (EMMCVPR 2009), held at the University of Bonn, Germany, August 24 28, 2009. These papers demonstrate that energy minimization methods have become a mature ?eld of research spanning a broad range of areas from discrete graph theoretic approaches and Markov random ?elds to variational methods and partial di?erential equations. Application areas include image segmentation and tracking, shape optimization and registration, inpainting and image deno- ing, color and texture modeling, statistics and learning. Overall, we received 75 high-quality double-blind submissions. Based on the reviewer recommendations, 36paperswereselectedforpublication,18asoraland18asposterpresentations. Both oral and poster papers were attributed the same number of pages in the conference proceedings. Furthermore, we were delighted that three leading experts from the ?elds of computer vision and energy minimization, namely, Richard Hartley (C- berra, Australia), Joachim Weickert (Saarbruc ken, Germany) and Guillermo Sapiro(Minneapolis,USA)agreedtofurtherenrichtheconferencewithinspiring keynote lectures.
