- 9782403000672
Vent et lumière : ces mots, les premiers d'un poème de Mao Tsé-toung, évoquent pour le narrateur une jeunesse évaporée comme le vent et la lumière. Une jeunesse dont l'expérience première fut un camp de concentration allemand, durant la dernière guerre, puis l'Asie découverte à vingt ans ou presque. C'est en compagnie d'un ami, Orso Mattei, rencontré en déportation et qui, né en Chine, lui avait proposé de le retrouver là-bas, que le jeune Ernest Lavisse découvre les traditions et le mystère de cette terre du bout du monde, dont le fleuve puissant, le Yang-tsé, roule, limoneux, parmi les remous d'une guerre civile. Cela se passe en 1949, au moment où Mao prend le pouvoir. Ce roman, qui touche à l'histoire et dont chaque détail est authentique, est aussi une histoire d'amour : la longue quête de deux hommes pour une seule et même femme, Ta Jiao-nü, la reine élue des pirates du Yang-tsé. Pour l'un, Orso Mattei, jeune médecin militaire, cette passion, noble d'abord, finira dans le sordide. Pour l'autre, Ernest Lavisse, ce sera un amour secret et sans illusions. Au fil des années, Orso Mattei se défait, comme la vie elle-même, et c'est cette défaite que Lavisse raconte dans un récit nostalgique, et dont les décors varient de la chute du IIIe Reich à la Chine de Mao, puis l'Indochine en guerre, Naples et sa misère, les Vosges et ses bêtes fugitives dans la forêt d'hiver.

Die Entwicklung immer leistungsfähigerer absoluter wie auch relativer Gravimeter mit deutlich verbesserter Messgenauigkeit ermglicht es, dass sich künftig nicht nur prägnante Schwereanomalien (wie z. B. die eines Salzstocks), sondern auch schwächere Signaturen erfassen und modellieren lassen. Mehr noch, die rasante Entwicklung der Computer führt zu neuartigen Methoden der Datendekomposition, wie z. B. Waveletdekorrelation. Dekorrelative Gravimetrie ist somit eine neue Explorationstechnik, die als kanonische Innovation aus der Verbindung neuartiger Mess- und Modellierungstechniken resultiert.Dekorrelative Gravimetrie dient der Reduzierung des Fündigkeitsrisikos von Aquiferen sowie von Gas- und Öllagerstätten, auch durch Vergleich und Zusammenschau alternativer, aber strukturell ähnlich gelagerter, dekorrelativer Verfahren wie etwa Magnetometrie und Seismik. Hier setzt dieses Buch mit einem exemplarischen Überblick über die neuartige Dekorrelationsmethoden der heutigenGeomathematik mit Hauptgewicht für den Fall der Gravimetrie an. Wesentliches mathematisches Hilfsmittel ist die Regularisierung des Newtonschen Volumenintegrals durch taylorisierte Mollifier-Varianten des Newton-Kerns.Ziel des vorliegenden Buches ist somit die Vermittlung des Grundverständnisses, dass Zooming-In Mollifier-Potentialmethoden wie etwa dekorrelative Gravimetrie neue wichtige Anwendungsfelder in der heutigen Geoexploration erffnen, insbesondere für Gebiete mit bergbaubedingten Hohlräumen oder sehr dichter Bebauung wie etwa das Saarland oder Sachsen, die den Einsatz von reflexionsseismischen Messungen erschweren oder sogar unmglich machen.Zusammenfassend lässt sich für dieses Buchprojekt festhalten, dass es einen Einblick in den aktuellen Stand gravimetrischer Multiskalenforschung vermittelt. Als wesentliches Resultat ergibt sich, dass die Schlüsseltechnologie Geomathematik in der Tat in der Lage ist, die Gravimetrie auf einfache, für Explorationszwecke zugängliche und somit rechenbare Dekorrelationsmodelle zu reduzieren. Mehr noch, das Buch macht auf diese Weise ein breites Publikum mit den vielfältigen Fragen und Problemen der heutigen Gravimetrie vertraut und setzt Denkanstße für eine erfolgreiche Weiterentwicklung und eine adäquate praxisrelevante Anwendbarkeit von Potentialmethoden in der Exploration in Gang.

"Asset Prices, Booms and Recessions" is a book on Financial Economics from a dynamic perspective. It focuses on the dynamic interaction of financial markets and economic activity. The financial markets to be studied here encompasses the money and bond market, credit market, stock market and foreign exchange market. Economic activity is described by the activity of firms, banks, households, governments and countries. The book shows how economic activity affects asset prices and the financial market and how asset prices and financial market volatility feed back to economic activity. The focus in this book is on theories, dynamic models and empirical evidence. Empirical applications relate to episodes of financial instability and financial crises of the U.S., Latin American, Asian as well as Euro-area countries. The current version of the book has moved to a more extensive coverage of the topics in financial economics by updating the literature in the appropriate chapters. Moreover it gives a more extensive treatment of new and more advanced topics in financial economics such as international portfolio theory, multi-agent and evolutionary approaches, capital asset pricing beyond consumption-based models and dynamic portfolio decisions. Overall, the book presents material that researchers and practitioners in financial engineering need to know about economic dynamics and that economists, practitioners and policy makers need to know about the financial market.

Sustainable Asset Accumulation and Dynamic Portfolio Decisions
Willi Semmler, Carl Chiarella, Chih-Ying Hsiao, Carl Mateane
- Springer
- 1 Septembre 2016
- 9783662492291
This book examines sustainable wealth formation and dynamic decision-making. The global economy experienced a veritable meltdown of asset markets in the years 2007-9, where many funds were overexposed to risky returns and suffered considerable losses. On the other hand, the long-term upswing in the stock market since 2010 has led to asset price booms and some new, but also uneven, wealth formation. In this book a broader set of constraints and guidelines for asset management and wealth accumulation is developed. The authors investigate how wealth formation and the proper management of financial funds can help to adequately buffer income risk and obtain sufficient risk-free income at a later stage of life, while also being socially and environmentally sustainable.The book explores behavioral and institutional rules for decision-making that reflect such constraints and guidelines, without necessarily being optimal in the narrow sense. The authors explain the need for such a dynamic decision-making and dynamic re-balancing of portfolios, by putting forward dynamic programming as an approach to dynamic decision-making that can allow sustainable wealth accumulation and dynamic asset allocation to be successfully integrated.This book provides a clear and comprehensive treatment of asset accumulation and dynamic portfolio models with an emphasis on long term and sustainable wealth formation. An important concern in public debate is the sustainability of our economy and this book employs cutting edge quantitative techniques and models to highlight important facts that cannot be disputed under any reasonable assumptions. It has the potential to become a standard reference for both academic researchers and quantitatively trained practitioners. Eckhard Platen, Professor of Quantitative Finance, University of Technology Sydney, Australia
This book should be read by both academics and practitioners alike. The former will find intellectually rigorous discussions and innovative solutions. The latter may find a few of the concepts a bit challenging. Yet, theory and technology are there to help simplify the work of those who worry about what time it is rather than how to make a watch--- but they do need a watch.Jean Brunel, Founder of Brunel Associates and Editor of The Journal of Wealth Management -
Reactive Flows, Diffusion and Transport
Willi Jager, Rolf Rannacher, J. Warnatz
- Springer
- 31 Mai 2007
- 9783540283966
The articles in this volume summarize the research results obtained in the former SFB 359 "Reactive Flow, Diffusion and Transport" which has been supported by the DFG over the period 1993-2004. The main subjects are physical-chemical processes sharing the difficulty of interacting diffusion, transport and reaction which cannot be considered separately. Typical examples are the chemical processes in flow reactors and in the catalytic combustion at surfaces. Further examples are models of star formation including diffusive mass transport, energy radiation and dust formation and the polluting transport in soil and waters. For these complex processes mathematical models are established and numerically simulated. The modeling uses multiscale techniques for nonlinear differential equations while for the numerical simulation and optimization goal-oriented mesh and model adaptivity, multigrid techniques and advanced Newton-type methods are developed combined with parallelization. This modeling and simulation is accompanied by experiments.

- 22 Octobre 2012
- 9783642280214
The sheer computing power of modern information technology is changing the face of research not just in science, technology and mathematics, but in humanities and cultural studies too. Recent decades have seen a major shift both in attitudes and deployment of computers, which are now vital and highly effective tools in disciplines where they were once viewed as elaborate typewriters. This revealing volume details the vast array of computing applications that researchers in the humanities now have recourse to, including the dissemination of scholarly information through virtual `co-laboratories', data retrieval, and the modeling of complex processes that contribute to our natural and cultural heritage. One key area covered in this book is the versatility of computers in presenting images and graphics, which is transforming the analysis of data sets and archaeological reconstructions alike. The papers published here are grouped into three broad categories that cover mathematical and computational methods, research developments in information systems, and a detailed portrayal of ongoing work on documenting, restoring and presenting cultural monuments including the temples in Pompeii and the Banteay Chhmar temples of the Angkorian period in present-day Cambodia. Originally presented at a research workshop in Heidelberg, Germany, they reflect the rapidly developing identity of computational humanities as an interdisciplinary field in its own right, as well as demonstrating the breadth of perspectives in this young and vibrant research area.

The second, enlarged edition of this established reference integrates many new insights into wastewater hydraulics. This work serves as a reference for researchers but also is a basis for practicing engineers. It can be used as a text book for graduate students, although it has the characteristics of a reference book. It addresses mainly the sewer hydraulician but also general hydraulic engineers who have to tackle many a problem in daily life, and who will not always find an appropriate solution. Each chapter is introduced with a summary to outline the contents. To illustrate application of the theory, examples are presented to explain the computational procedures. Further, to relate present knowledge to the history of hydraulics, some key dates on noteworthy hydraulicians are quoted. A historical note on the development of wastewater hydraulics is also added. References are given at the end of each chapter, and they are often helpful starting points for further reading. Each notation is defined when introduced, and listed alphabetically at the end of each chapter. This new edition includes in particular sideweirs with throttling pipes, drop shafts with an account on the two-phase flow features, as well as conduit choking due to direct or undular hydraulic jumps.

- Birkhäuser
- 17 Mai 2019
- 9783030130541
The authors introduce geomathematics as an active research area to a wider audience.
Chapter 1 presents an introduction to the Earth as a system to apply scientific methods. Emphasis is laid on transfers from virtual models to reality and vice versa.
In the second chapter geomathematics is introduced as a new scientific area which nevertheless has its roots in antiquity. The modern conception of geomathematics is outlined from different points of view and its challenging nature is described as well as its interdisciplinarity. Geomathematics is shown as the bridge between the real world and the virtual world. The complex mathematical tools are shown from a variety of fields necessary to tackle geoscientific problems in the mathematical language.
Chapter 3 contains some exemplary applications as novel exploration methods. Particular importance is laid on the change of language when it comes to translate measurements to mathematical models. New solution methods like the multiscale mollifier technique are presented. Further applications discussed are aspects of reflection seismics.
Chapter 4 is devoted to the short description of recent activities in geomathematics.
The Appendix (Chapter 5) is devoted to the GEM - International Journal on Geomathematics founded ten years ago. Besides a detailed structural analysis of the editorial goals an index of all papers published in former issues is given. -
This book presents the theory and computation of open channel flows, using detailed analytical, numerical and experimental results. The fundamental equations of open channel flows are derived by means of a rigorous vertical integration of the RANS equations for turbulent flow. In turn, the hydrostatic pressure hypothesis, which forms the core of many shallow water hydraulic models, is scrutinized by analyzing its underlying assumptions. The book's main focus is on one-dimensional models, including detailed treatments of unsteady and steady flows. The use of modern shock capturing finite difference and finite volume methods is described in detail, and the quality of solutions is carefully assessed on the basis of analytical and experimental results.The book's unique features include:o Rigorous derivation of the hydrostatic-based shallow water hydraulic modelso Detailed treatment of steady open channel flows, including the computation of transcritical flow profileso General analysis of gate maneuvers as the solution of a Riemann problemo Presents modern shock capturing finite volume methods for the computation of unsteady free surface flowso Introduces readers to movable bed and sediment transport in shallow water modelso Includes numerical solutions of shallow water hydraulic models for non-hydrostatic steady and unsteady free surface flowsThis book is suitable for both undergraduate and graduate level students, given that the theory and numerical methods are progressively introduced starting with the basics. As supporting material, a collection of source codes written in Visual Basic and inserted as macros in Microsoft Excel® is available. The theory is implemented step-by-step in the codes, and the resulting programs are used throughout the book to produce the respective solutions.
