Available in PDF, EPUB and Kindle. Book excerpt: Using numerous examples, this book helps physicists and engineers to solve partial differential equations (PDEs), by using finite element analysis (FEA), occurring in various fields of physics, such as gravity, heat conduction, electricity and magnetism, elastic deformation and liquid flow. The examples are treated by means of a novel program (PDEase), but it is not necessary to have this software available to make the most of the power of FEA and to gain insight into the phenomena connected with fields.
Download or read book An Introduction to Optimal Estimation of Dynamical Systems written by J.L. Junkins and published by Springer. This book was released on 1978-07-31 with total page 498 pages. Available in PDF, EPUB and Kindle. Book excerpt: This text 1s designed to introduce the fundamentals of esti mation to engineers, scientists, and applied mathematicians. The level of the presentation should be accessible to senior under graduates and should prove especially well-suited as a self study guide for practicing professionals. My primary motivation for writing this book 1s to make a significant contribution toward minimizing the painful process most newcomers must go through in digesting and applying the theory. Thus the treatment 1s intro ductory and essence-oriented rather than comprehensive. While some original material 1s included, the justification for this text lies not in the contribution of dramatic new theoretical re sults, but rather in the degree of success I believe that I have achieved in providing a source from which this material may be learned more efficiently than through study of an existing text or the rather diffuse literature. This work is the outgrowth of the author's mid-1960's en counter with the subject while motivated by practical problems aSSociated with space vehicle orbit determination and estimation of powered rocket trajectories. The text has evolved as lecture notes for short courses and seminars given to professionals at Pr>efaae various private laboratories and government agencies, and during the past six years, in conjunction with engineering courses taught at the University of Virginia. To motivate the reader's thinking, the structure of a typical estimation problem often assumes the following form: • Given a dynamical system, a mathematical model is hypothesized based upon the experience of the investigator.

Download or read book Sustainable Development Risks and Risk Management written by Elena G. Popkova and published by Springer Nature. This book was released on 2023-10-19 with total page 587 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book is devoted to a systemic study of socio-economic development risks arising in the Decade of Action, as well as the prospects for risk management in support of sustainable development. It aims to overcome fragmentary consideration of risks in the existing literature through their comprehensive coverage and the establishment of their interconnections from the perspective of sustainable development. The novelty of this book is that it provides a comprehensive accounting of socio-economic development risks in the Decade of Action, as well as a rethinking of these risks from a sustainable development perspective. The book also opens up the possibility of the most comprehensive and effective risk management in support of sustainable development. The practical relevance of the book stems from the fact that it describes and discusses practical experience in detail and accompanies the theoretical material with numerous case studies, including cases and frameworks with extensive coverage of international best practices. The book is intended for scholars, for whom the book forms a systemic scientific view of the risks of socio-economic development arising in the Decade of Action, as well as the prospects for risk management in support of sustainable development. The book is also of interest to practitioners, for whom it offers practical advice on risk management at all levels of the economy for sustainable development. Many examples from different countries make the book attractive to a wide international audience. The book is of particular interest to readers from Russia.

Download or read book Compatible Finite Element Methods for Geophysical Flows written by Thomas H. Gibson and published by Springer Nature. This book was released on 2019-08-26 with total page 118 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book introduces recently developed mixed finite element methods for large-scale geophysical flows that preserve essential numerical properties for accurate simulations. The methods are presented using standard models of atmospheric flows and are implemented using the Firedrake finite element library. Examples guide the reader through problem formulation, discretisation, and automated implementation. The so-called “compatible” finite element methods possess key numerical properties which are crucial for real-world operational weather and climate prediction. The authors summarise the theory and practical implications of these methods for model problems, introducing the reader to the Firedrake package and providing open-source implementations for all the examples covered. Students and researchers with engineering, physics, mathematics, or computer science backgrounds will benefit from this book. Those readers who are less familiar with the topic are provided with an overview of geophysical fluid dynamics.
Download or read book Composition Deep Structure and Evolution of Continents written by R.D. van der Hilst and published by Elsevier. This book was released on 1999-10-22 with total page 341 pages. Available in PDF, EPUB and Kindle. Book excerpt: The ensemble of manuscripts presented in this special volume captures the stimulating cross-disciplinary dialogue from the International Symposium on Deep Structure, Composition, and Evolution of Continents, Harvard University, Cambridge, Massachusetts, 15-17 October 1997. It will provide an update on recent research developments and serve as a starting point for research of the many outstanding issues. After its formation at mid-oceanic spreading centers, oceanic lithosphere cools, thickens, and subsides, until it subducts into the deep mantle beneath convergent margins. As a result of this continuous recycling process oceanic lithosphere is typically less than 200 million years old (the global average is about 80 Myr). A comprehensive, multi-disciplinary study of continents involves a wide range of length scales: tiny rock samples and diamond inclusions may yield isotope and trace element signatures diagnostic for the formation age and evolution of (parts of) cratons, while geophysical techniques (e.g., seismic and electromagnetic imaging) constrain variations of elastic and conductive properties over length scales ranging from several to many thousand kilometers. Integrating and reconciling this information is far from trivial and, as several papers in this volume document, the relationships between, for instance, formation age and tectonic behavior on the one hand and the seismic signature, heat flow, and petrology on the other may not be uniform but may vary both within as well as between cratons. These observations complicate attempts to determine the variations of one particular observable (e.g., heat flow, lithosphere thickness) as a function of another (e.g., crustal age) on the basis of global data compilations and tectonic regionalizations. Important conclusions of the work presented here are that (1) continental deformation, for instance shortening, is not restricted to the crust but also involves the lithospheric mantle; (2) the high wavespeed part of continental lithospheric mantle is probably thinner than inferred previously from vertically travelling body waves or form global surface-wave models; and (3) the seismic signature of ancient continents is more complex than expected from a uniform relationship with crustal age.
