This book is intended as a text for a one-semester course on Mathematical and Computational Neuroscience for upper-level undergraduate and beginning graduate students of mathematics, the natural sciences, engineering, or computer science. An undergraduate introduction to differential equations is more than enough mathematical background. Only a slim, high school-level background in physics is assumed, and none in biology. Topics include models of individual nerve cells and their dynamics, models of networks of neurons coupled by synapses and gap junctions, origins and functions of population rhythms in neuronal networks, and models of synaptic plasticity. An extensive online collection of Matlab programs generating the figures accompanies the book.

The articles collected in this volume are based on lectures given at the IMA Workshop, "Computational Radiology and Imaging: Therapy and Diagnostics", March 17-21, 1997. Introductory articles by the editors have been added. The focus is on inverse problems involving electromagnetic radiation and particle beams, with applications to X-ray tomography, nuclear medicine, near-infrared imaging, microwave imaging, electron microscopy, and radiation therapy planning. Mathematical and computational tools and models which play important roles in this volume include the X-ray transform and other integral transforms, the linear Boltzmann equation and, for near-infrared imaging, its diffusion approximation, iterative methods for large linear and non-linear least-squares problems, iterative methods for linear feasibility problems, and optimization methods. The volume is intended not only for mathematical scientists and engineers working on these and related problems, but also for non-specialists. It contains much introductory expository material, and a large number of references. Many unsolved computational and mathematical problems of substantial practical importance are pointed out.

Vordiplomarbeit aus dem Jahr 2009 im Fachbereich Medien / Kommunikation - Sonstiges, Note: 1,3, Universitat Hildesheim (Stiftung), Sprache: Deutsch, Abstract: Anhand einer Analyse des Films The Dark Knight" (USA 2008) beschaftigt sich diese Arbeit mit dem innerfilmischen Helden-Diskurs. Neben Batman bzw. Bruce Wayne werden die unterschiedlichsten Typen von Helden in ihren Beweggrunden und Taten dargestellt. Der Held ist in Christopher Nolans Film sowohl Hilfe als auch Problem fur die Gesellschaft. Diese ist standig gezwungen, sich zu ihrem Helden neu zu positionieren. Dabei werden sowohl einige Einzelpersonen als auch die Gesamtgesellschaft in ihren Standpunkten und Entwicklungen untersucht. In der Betrachtung wird zudem Bezug genommen auf ausserfilmische, kontemporare politische und gesellschaftliche Diskussionen, wie sie unter dem Eindruck der terroristischen Bedrohung des 21. Jahrhunderts vorherrschen
