This book was released on 2001 with total page 186 pages. Available in PDF, EPUB and Kindle. Book excerpt: In this thesis, I study two nonlinear evolution partial differential equations whose solutions may blow-up in finite time. In the first part, I consider the nonlinear Schrödinger equation with critical exponent in the space periodic case and obtain a lower bound for the blow-up rate under the condition of minimal mass. In parts 2 and 3, I study a semi-linear wave equation. In part 2 we obtain optimal bounds on the blow-up rate, and in part 3 I study the asymptotic behaviour to solutions of this equation.

This book was released on 1987 with total page 144 pages. Available in PDF, EPUB and Kindle. Book excerpt: Ce travail est composé de quatre articles.Dans le premier nous définissons de manière intrinsèque le concept de front d'onde d'une sous-variété de régularité Höldérienne ou Sobolev limitée. Puis nous utilisons cette notion pour étudier les singularités microlocales de solutions d'équations aux dérivées partielles non linéaires dans plusieurs situations: équations du premier ordre, de Monge-Ampère, système de Pfaff.Dans le second article, nous étudions le problème d'interaction des singularités pour un opérateur pseudodifférentiel à symbole principal réel et dont la variété caractéristique est la réunion de deux hyper surfaces lisses d'interaction non involutive.Dans le troisième article, nous construisons pour un opérateur quasi-linéaire holomorphe des solutions holomorphes ramifiées autour d'une hypersurface complexe lisse caractéristique.Dans le quatrième article, nous étudions la régularité microlocale des solutions des problèmes de Dirichlet non linéaires non caractéristiques d'ordre deux à bord peu régulier.

Download or read book The Mediterranean region under climate change written by Collectif and published by IRD Éditions. This book was released on 2018-11-19 with total page 736 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book has been published by Allenvi (French National Alliance for Environmental Research) to coincide with the 22nd Conference of Parties to the United Nations Framework Convention on Climate Change (COP22) in Marrakesh. It is the outcome of work by academic researchers on both sides of the Mediterranean and provides a remarkable scientific review of the mechanisms of climate change and its impacts on the environment, the economy, health and Mediterranean societies. It will also be valuable in developing responses that draw on “scientific evidence” to address the issues of adaptation, resource conservation, solutions and risk prevention. Reflecting the full complexity of the Mediterranean environment, the book is a major scientific contribution to the climate issue, where various scientific considerations converge to break down the boundaries between disciplines.
Download or read book The European Landscape Convention written by Michael Jones and published by Springer Science & Business Media. This book was released on 2011-02-09 with total page 327 pages. Available in PDF, EPUB and Kindle. Book excerpt: This important and insightful book provides, for the first time, a broad presentation of ongoing research into public participation in landscape conservation, management and planning, following the 2000 European Landscape Convention which came into force in 2004. The book examines both the theory of participation and what lessons can be learnt from specific European examples. It explores in what manner and to what extent the provisions for participation in the European Landscape Convention have been followed up and implemented. It also presents and compares different experiences of participation in selected countries from northern, southern, eastern and western Europe, and provides a critical examination of public participation in practice. However, while the book’s focus is necessarily on Europe, many of the conclusions drawn are of global relevance. The book provides a valuable reference for researchers and advanced students in landscape policies and management, as well as for professionals and others interested in land-use planning and environmental management.
Download or read book Amongst Mathematicians written by Elena Nardi and published by Springer Science & Business Media. This book was released on 2008 with total page 349 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book offers a unique perspective on ways in which mathematicians: perceive their students' learning; teach; reflect on their teaching practice. Elena Nardi achieves this by employing two fictional, yet entirely data-grounded, characters to create a conversation on these important issues. The construction of these characters is based on large bodies of data including intense focused group interviews with mathematicians and extensive analyses of students' written work, collected and analyzed over a substantial period.

Download or read book Groundwater Modelling in Arid and Semi Arid Areas written by Howard S. Wheater and published by Cambridge University Press. This book was released on 2010-09-09 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Arid and semi-arid regions face major challenges in the management of scarce freshwater resources under pressures of population, economic development, climate change, pollution and over-abstraction. Groundwater is commonly the most important water resource in these areas. Groundwater models are widely used globally to understand groundwater systems and to guide decisions on management. However, the hydrology of arid and semi-arid areas is very different from that of humid regions, and there is little guidance on the special challenges of groundwater modelling for these areas. This book brings together the experience of internationally leading experts to fill a gap in the scientific and technical literature. It introduces state-of-the-art methods for modelling groundwater resources, illustrated with a wide-ranging set of illustrative examples from around the world. The book is valuable for researchers, practitioners in developed and developing countries, and graduate students in hydrology, hydrogeology, water resources management, environmental engineering and geography.
Download or read book Working with the Anthropological Theory of the Didactic in Mathematics Education written by Marianna Bosch and published by Routledge. This book was released on 2019-10-23 with total page 271 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book presents the main research veins developed within the framework of the Anthropological Theory of the Didactic (ATD), a paradigm that originated in French didactics of mathematics. While a great number of publications on ATD are available in French and Spanish, Working with the Anthropological Theory of the Didactic in Mathematics Education is the first directed at English-speaking international audiences. Written and edited by leading researchers in ATD, the book covers all aspects of ATD theory and practice, including teaching applications. The chapters feature the most relevant and recent investigations presented at the 6th international conference on the ATD, offering a unique opportunity for an international audience interested in the study of mathematics teaching and learning to keep in touch with advances in educational research. The book is divided into four sections and the contributions explore key topics such as: The core concept of ‘praxeology’, including its development and functionalities The need for new teaching praxeologies in the paradigm of questioning the world The impact of ATD on the teaching profession and the education of teachers This is the second volume in the New Perspectives on Research in Mathematics Education. This comprehensive casebook is an indispensable resource for researchers, teachers and graduate students around the world.

Download or read book Mathematics Mathematics Education Searching for Common Ground written by Michael N. Fried and published by Springer Science & Business Media. This book was released on 2013-11-29 with total page 385 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book is the fruit of a symposium in honor of Ted Eisenberg concerning the growing divide between the mathematics community and the mathematics education community, a divide that is clearly unhealthy for both. The work confronts this disturbing gap by considering the nature of the relationship between mathematics education and mathematics, and by examining areas of commonality as well as disagreement. It seeks to provide insight into the mutual benefit both stand to gain by building bridges based on the natural bonds between them.

Download or read book How Humans Learn to Think Mathematically written by David Tall and published by Cambridge University Press. This book was released on 2013-09-02 with total page 483 pages. Available in PDF, EPUB and Kindle. Book excerpt: How Humans Learn to Think Mathematically describes the development of mathematical thinking from the young child to the sophisticated adult. Professor David Tall reveals the reasons why mathematical concepts that make sense in one context may become problematic in another. For example, a child's experience of whole number arithmetic successively affects subsequent understanding of fractions, negative numbers, algebra, and the introduction of definitions and proof. Tall's explanations for these developments are accessible to a general audience while encouraging specialists to relate their areas of expertise to the full range of mathematical thinking. The book offers a comprehensive framework for understanding mathematical growth, from practical beginnings through theoretical developments, to the continuing evolution of mathematical thinking at the highest level.
