Fundamentals of Cavitation
Jean-Pierre Franc, Jean-Marie Michel
- Springer
- 22 Janvier 2006
- 9781402022333
This book treats cavitation, which is a unique phenomenon in the field of hyd- dynamics, although it can occur in any hydraulic machinery such as pumps, propellers, artificial hearts, and so forth. Cavitation is generated not only in water, but also in any kind of fluid, such as liquid hydrogen. The generation of cavitation can cause severe damage in hydraulic machinery. Therefore, the prevention of cavitation is an important concern for designers of hydraulic machinery. On the contrary, there is great potential to utilize cavitation in various important applications, such as environmental protection. There have been several books published on cavitation, including one by the same authors. This book differs from those previous ones, in that it is both more physical and more theoretical. Any theoretical explanation of the cavitation phenomenon is rather difficult, but the authors have succeeded in explaining it very well, and a reader can follow the equations easily. It is an advantage in reading this book to have some understanding of the physics of cavitation. Therefore, this book is not an introductory text, but a book for more advanced study. However, this does not mean that this book is too difficult for a beginner, because it explains the cavitation phenomenon using many figures. Therefore, even a beginner on cavitation can read and can understand what cavitation is. If the student studies through this book (with patience), he or she can become an expert on the physics of cavitation.

Advanced Experimental and Numerical Techniques for Cavitation Erosion Prediction
Jean-Pierre Franc, Ki-Han Kim, Georges Chahine, Ayat Karimi
- Springer
- 8 Juillet 2014
- 9789401785396
This book provides a comprehensive treatment of the cavitation erosion phenomenon and state-of-the-art research in the field. It is divided into two parts. Part 1 consists of seven chapters, offering a wide range of computational and experimental approaches to cavitation erosion. It includes a general introduction to cavitation and cavitation erosion a detailed description of facilities and measurement techniques commonly used in cavitation erosion studies, an extensive presentation of various stages of cavitation damage (including incubation and mass loss) and insights into the contribution of computational methods to the analysis of both fluid and material behavior. The proposed approach is based on a detailed description of impact loads generated by collapsing cavitation bubbles and a physical analysis of the material response to these loads. Part 2 is devoted to a selection of nine papers presented at the International Workshop on Advanced Experimental and Numerical Techniques for Cavitation Erosion Prediction (Grenoble, France, 1-2 March 2011) representing the forefront of research on cavitation erosion. Innovative numerical and experimental investigations illustrate the most advanced breakthroughs in cavitation erosion research.

Interaktionsspiele bei Psychopathie
Rainer Sachse, Fritjof Von Franque
- Springer
- 14 Octobre 2019
- 9783662592793
Im vorliegenden Buch wird beschrieben, wie manipulatives Handeln von Personen mit Psychopathie erkannt und bewältigt werden kann. Die psychopathische Persnlichkeitsstrung (engl.: Psychopathy) ist definiert durch eine Kombination aus interaktionellen, affektiven, antisozialen und sich im Lebensstil ausdrückenden Besonderheiten, zu denen Egozentrizität, manipulierendes Verhalten, ein Mangel an Mitgefühl, Schuld und Reue, pathologisches Lügen, Verantwortungslosigkeit sowie die kontinuierliche Verletzung sozialer Normen und Erwartungen zählen. Fachleute haben vor allem Schwierigkeiten, mit den interpersonellen Merkmalen dieser Strung umzugehen. Dieses Buch bietet hierfür konkrete Unterstützung. Geschrieben für Psychotherapeuten, Coaches, Diagnostiker, Psychiater, forensische Psychologen und alle, die beruflich mit Psychopathen zu tun haben. Die Autoren: Prof. Dr. Rainer Sachse ist Psychologischer Psychotherapeut, Begründer der Klärungsorientierten Psychotherapie und Leiter des Instituts für Psychologische Psychotherapie (IPP) in Bochum. Fritjof von Franqué ist sexualforensischer Psychotherapeut und leitender Psychologe am Institut für Sexualforschung und Forensische Psychiatrie des Universitätsklinikums Hamburg-Eppendorf (UKE).

Minimal Surfaces from a Complex Analytic Viewpoint
Antonio Alarcon, Franc Forstneric, Francisco J. Lopez
- Springer
- 10 Mars 2021
- 9783030690564
This monograph offers the first systematic treatment of the theory of minimal surfaces in Euclidean spaces by complex analytic methods, many of which have been developed in recent decades as part of the theory of Oka manifolds (the h-principle in complex analysis). It places particular emphasis on the study of the global theory of minimal surfaces with a given complex structure. Advanced methods of holomorphic approximation, interpolation, and homotopy classification of manifold-valued maps, along with elements of convex integration theory, are implemented for the first time in the theory of minimal surfaces. The text also presents newly developed methods for constructing minimal surfaces in minimally convex domains of Rn, based on the Riemann-Hilbert boundary value problem adapted to minimal surfaces and holomorphic null curves. These methods also provide major advances in the classical Calabi-Yau problem, yielding in particular minimal surfaces with the conformal structure of any given bordered Riemann surface.Offering new directions in the field and several challenging open problems, the primary audience of the book are researchers (including postdocs and PhD students) in differential geometry and complex analysis. Although not primarily intended as a textbook, two introductory chapters surveying background material and the classical theory of minimal surfaces also make it suitable for preparing Masters or PhD level courses.

This book, now in a carefully revised second edition, provides an up-to-date account of Oka theory, including the classical Oka-Grauert theory and the wide array of applications to the geometry of Stein manifolds.
Oka theory is the field of complex analysis dealing with global problems on Stein manifolds which admit analytic solutions in the absence of topological obstructions. The exposition in the present volume focuses on the notion of an Oka manifold introduced by the author in 2009. It explores connections with elliptic complex geometry initiated by Gromov in 1989, with the Andersén-Lempert theory of holomorphic automorphisms of complex Euclidean spaces and of Stein manifolds with the density property, and with topological methods such as homotopy theory and the Seiberg-Witten theory.
Researchers and graduate students interested in the homotopy principle in complex analysis will find this book particularly useful. It is currently the only work that offers a comprehensive introduction to both the Oka theory and the theory of holomorphic automorphisms of complex Euclidean spaces and of other complex manifolds with large automorphism groups.
