Taschenbuch. Zustand: Neu. Druck auf Anfrage Neuware - Printed after ordering - Respiratory motion causes an important uncertainty in radiotherapy planning of the thorax and upper abdomen. The main objective of radiation therapy is to eradicate or shrink tumor cells without damaging the surrounding tissue by delivering a high radiation dose to the tumor region and a dose as low as possible to healthy organ tissues. Meeting this demand remains a challenge especially in case of lung tumors due to breathing-induced tumor and organ motion where motion amplitudes can measure up to several centimeters. Therefore, modeling of respiratory motion has become increasingly important in radiation therapy. With 4D imaging techniques spatiotemporal image sequences can be acquired to investigate dynamic processes in the patient's body. Furthermore, image registration enables the estimation of the breathing-induced motion and the description of the temporal change in position and shape of the structures of interest by establishing the correspondence between images acquired at different phases of the breathing cycle. In radiation therapy these motion estimations are used to define accurate treatment margins, e.g. to calculate dose distributions and to develop prediction models for gated or robotic radiotherapy. In this book, the increasing role of image registration and motion estimation algorithms for the interpretation of complex 4D medical image sequences is illustrated. Different 4D CT image acquisition techniques and conceptually different motion estimation algorithms are presented. The clinical relevance is demonstrated by means of example applications which are related to the radiation therapy of thoracic and abdominal tumors. The state of the art and perspectives are shown by an insight into the current field of research. The book is addressed to biomedical engineers, medical physicists, researchers and physicians working in the fields of medical image analysis, radiology and radiation therapy.

Taschenbuch. Zustand: Neu. Druck auf Anfrage Neuware - Printed after ordering - This book discusses the state-of-the-art and open problems in computational finance. It presents a collection of research outcomes and reviews of the work from the STRIKE project, an FP7 Marie Curie Initial Training Network (ITN) project in which academic partners trained early-stage researchers in close cooperation with a broader range of associated partners, including from the private sector. The aim of the project was to arrive at a deeper understanding of complex (mostly nonlinear) financial models and to develop effective and robust numerical schemes for solving linear and nonlinear problems arising from the mathematical theory of pricing financial derivatives and related financial products. This was accomplished by means of financial modelling, mathematical analysis and numerical simulations, optimal control techniques and validation of models. In recent years the computational complexity of mathematical models employed in financial mathematics has witnessed tremendous growth. Advanced numerical techniques are now essential to the majority of present-day applications in the financial industry. Special attention is devoted to a uniform methodology for both testing the latest achievements and simultaneously educating young PhD students. Most of the mathematical codes are linked into a novel computational finance toolbox, which is provided in MATLAB and PYTHON with an open access license. The book offers a valuable guide for researchers in computational finance and related areas, e.g. energy markets, with an interest in industrial mathematics.

Taschenbuch. Zustand: Neu. Druck auf Anfrage Neuware - Printed after ordering - Studienarbeit aus dem Jahr 2009 im Fachbereich Deutsch - Pädagogik, Didaktik, Sprachwissenschaft, Note: 2, Christian-Albrechts-Universität Kiel (Germanistisches Seminar), Veranstaltung: Deutsche Studenten- und Schülersprache in Geschichte, Gegenwart und Deutschunterricht, Sprache: Deutsch, Abstract: Die letzten Jahrzehnte haben auf dem Gebiet der deutschen Jugendsprachforschung erhebliche Fortschritte gebracht. Jedoch gibt es noch immer Lücken, die es zu schließen gilt. Vor allem die Zeit der national-sozialistischen Diktatur 1933-1945 ist auf diesen sprachwissenschaftlichen Aspekt hin bis heute nur unzureichend untersucht worden. Dabei lassen sich zahlreiche Fragen stellen:Gab es eine spezifische Schülersprache in jener Zeit Welchen Einflüssen unterlag sie Gab es Formen sprachlichen Widerstandes Diese Arbeit erhebt keineswegs den Anspruch Antworten auf diese Fragen zu geben. Sie soll vielmehr als Vorarbeit für eine gezielte Quellenarbeit dienen, die unerlässlich für die weitere Untersuchung des Forschungsgegenstandes ist. Die Arbeit will versuchen, an Hand weniger Beispielen mögliche Einflüsse auf eine eventuell existierende Schülersprache im Nationalsozialismus aufzuzeigen und dadurch Hinweise auf Quellen zu geben.
