There has been considerable analysis of the potential for spontaneous combustion of individual kegs of self-heating materials, such as calcium hypochlorite. However, when arrays of such kegs are shipped in a single closed container, interaction effects become significant, and the critical value of the external temperature for self-ignition is significantly lowered. In this book, we consider the extent to which simple models, which are amenable to analytic treatment, can mimic this behaviour: thus we extend the well-known Frank-Kamenetskii approximation to a 2D model with infinite height to...

Studienarbeit aus dem Jahr 2013 im Fachbereich Germanistik - Semiotik, Pragmatik, Semantik, Note: 1,3, Universitat Bayreuth, Veranstaltung: Interkulturelle Germanistik, Sprache: Deutsch, Abstract: Die vorliegende Arbeit erkundet die drei prototypischen Eigenschaften der gesprochenen Sprache, namlich ihre Prozesshaftigkeit, ihre Multimodalitat und ihre Interaktivitat. Als Grundlage dienen die Theorien von Reinhard Fiehler, Birgit Barden, Mechthild Elstermann sowie Barbara Kraft. Um diese Eigenschaften zu verstehen, werden im Folgenden konkrete Beispiele dargestellt, um zu zeigen, wie sich...

With the vast development of Internet capacity and speed, as well as wide adop- tion of media technologies in people's daily life, a large amount of videos have been surging, and need to be efficiently processed or organized based on interest. The human visual perception system could, without difficulty, interpret and r- ognize thousands of events in videos, despite high level of video object clutters, different types of scene context, variability of motion scales, appearance changes, occlusions and object interactions. For a computer vision system, it has been be very challenging to achieve...

This thesis examines laser generation from the ultraviolet to the short edge of the mid-infrared band by exploiting the nonlinear effects in photonic crystal fibers (PCFs). Several different physical mechanisms are investigated by using homemade PCFs with elaborately customized dispersion profiles. A particular focus is on the development of fiber optical parametric amplifiers (FOPAs) and oscillators (FOPOs) based on the PCFs with a zero-dispersion wavelength of ca.1.06 μm. In particular, several schemes are proposed for solving the key problems involved in the application of FOPOs....
