The obstacle problem

The obstacle problem PDF Author: Luis Angel Caffarelli
Publisher: Edizioni della Normale
ISBN: 9788876422492
Category : Mathematics
Languages : en
Pages : 0

Book Description
The material presented here corresponds to Fermi lectures that I was invited to deliver at the Scuola Normale di Pisa in the spring of 1998. The obstacle problem consists in studying the properties of minimizers of the Dirichlet integral in a domain D of Rn, among all those configurations u with prescribed boundary values and costrained to remain in D above a prescribed obstacle F. In the Hilbert space H1(D) of all those functions with square integrable gradient, we consider the closed convex set K of functions u with fixed boundary value and which are greater than F in D. There is a unique point in K minimizing the Dirichlet integral. That is called the solution to the obstacle problem.

Higher Order Dynamic Mode Decomposition and Its Applications

Higher Order Dynamic Mode Decomposition and Its Applications PDF Author: Jose Manuel Vega
Publisher: Academic Press
ISBN: 0128227664
Category : Technology & Engineering
Languages : en
Pages : 322

Book Description
Higher Order Dynamic Mode Decomposition and Its Applications provides detailed background theory, as well as several fully explained applications from a range of industrial contexts to help readers understand and use this innovative algorithm. Data-driven modelling of complex systems is a rapidly evolving field, which has applications in domains including engineering, medical, biological, and physical sciences, where it is providing ground-breaking insights into complex systems that exhibit rich multi-scale phenomena in both time and space. Starting with an introductory summary of established order reduction techniques like POD, DEIM, Koopman, and DMD, this book proceeds to provide a detailed explanation of higher order DMD, and to explain its advantages over other methods. Technical details of how the HODMD can be applied to a range of industrial problems will help the reader decide how to use the method in the most appropriate way, along with example MATLAB codes and advice on how to analyse and present results. Includes instructions for the implementation of the HODMD, MATLAB codes, and extended discussions of the algorithm Includes descriptions of other order reduction techniques, and compares their strengths and weaknesses Provides examples of applications involving complex flow fields, in contexts including aerospace engineering, geophysical flows, and wind turbine design

Mediterranean Type Ecosystems

Mediterranean Type Ecosystems PDF Author: Francesco di Castri
Publisher: Springer Science & Business Media
ISBN: 3642655203
Category : Science
Languages : en
Pages : 410

Book Description
No other disjunct pieces of land present such striking similarities as the widely sepa 1 rated regions with a mediterranean type of climate, that is, the territories fringing the Mediterranean Sea, California, Central Chile and the southernmost strips of South Mrica and Australia. Similarities are not confined to climatic trends, but are also reflected in the physiognomy ofthe vegetation, in land use patterns and frequently in the general appearance of the landscape. The very close similarities in agricultural practices and sometimes also in rural settlements are dependent on the climatic and edaphic analogies, as well as on a certain commonality in qdtural history. This is certainly true for the Mediterranean Sea basin which in many ways represents a sort of ecological-cultural unit; this is also valid for CaUfornia and Chile, which were both settled by Spaniards and which showed periods of vigorous commercial and cultural interchanges as during the California gold rush. One other general feature is the massive interchange of cultivated and weed species of plants that has occurred between the five areas of the world that have a mediterranean-type climate, with the Mediterranean basin region itself as a major source. In spite of their limited territorial extension, probably no other parts of the world have played a more fundamental role in the history of mankind. Phoenician, Etruscan, Hellenic, Jewish, Roman, Christian andArab civilizations, among others,haveshapedmanyofman's present attitudes, including his position and perception vis-a-vis nature.

Party-System Collapse

Party-System Collapse PDF Author: Jason Seawright
Publisher: Stanford University Press
ISBN: 0804783926
Category : Political Science
Languages : en
Pages : 311

Book Description
Most party systems are relatively stable over time. Yet in the 1980s and 1990s, established party systems in Peru and Venezuela broke down, leading to the elections of outsider Alberto Fujimori and anti-party populist Hugo Chavez. Focusing on these two cases, this book explores the causes of systemic collapse. To date, scholars have pointed to economic crises, the rise of the informal economy, and the charisma and political brilliance of Fujimori and Chavez to explain the changes in Peru and Venezuela. This book uses economic data, surveys, and experiments to show that these explanations are incomplete. Political scientist Jason Seawright argues that party-system collapse is motivated fundamentally by voter anger at the traditional political parties, which is produced by corruption scandals and failures of representation. Integrating economic, organizational, and individual considerations, Seawright provides a new explanation and compelling new evidence to present a fuller picture of voters' decisions and actions in bringing about party-system collapse, and the rise of important outsider political leaders in South America.

The Question Concerning Technology in China

The Question Concerning Technology in China PDF Author: Yuk Hui
Publisher: MIT Press
ISBN: 0995455007
Category : Philosophy
Languages : en
Pages : 347

Book Description
A systematic historical survey of Chinese thought is followed by an investigation of the historical-metaphysical questions of modern technology, asking how Chinese thought might contribute to a renewed questioning of globalized technics. Heidegger's critique of modern technology and its relation to metaphysics has been widely accepted in the East. Yet the conception that there is only one—originally Greek—type of technics has been an obstacle to any original critical thinking of technology in modern Chinese thought. Yuk Hui argues for the urgency of imagining a specifically Chinese philosophy of technology capable of responding to Heidegger's challenge, while problematizing the affirmation of technics and technologies as anthropologically universal. This investigation of the historical-metaphysical question of technology, drawing on Lyotard, Simondon, and Stiegler, and introducing a history of modern Eastern philosophical thinking largely unknown to Western readers, including philosophers such as Feng Youlan, Mou Zongsan, and Keiji Nishitani, sheds new light on the obscurity of the question of technology in China. Why was technics never thematized in Chinese thought? Why has time never been a real question for Chinese philosophy? How was the traditional concept of Qi transformed in its relation to Dao as China welcomed technological modernity and westernization? In The Question Concerning Technology in China, a systematic historical survey of the major concepts of traditional Chinese thinking is followed by a startlingly original investigation of these questions, in order to ask how Chinese thought might today contribute to a renewed, cosmotechnical questioning of globalized technics.
