This book was released on 2008-07-01 with total page 287 pages. Available in PDF, EPUB and Kindle. Book excerpt: Following the publication of C. S. Holling's seminal work on the relationship between animal body mass patterns and scale-specific landscape structure, ecologists began to explore the theoretical and applied consequences of discontinuities in ecosystems and other complex systems. Are ecosystems and their components continuously distributed and do they adhere to scaling laws, or are they discontinuous and more complex than early models would have us believe? The resulting propositions over the structure of complex systems sparked an ongoing debate regarding the mechanisms generating discontinuities and the statistical methods used for their detection. This volume takes the view that ecosystems and other complex systems are inherently discontinuous and that such fields as ecology, economics, and urban studies greatly benefit from this paradigm shift. Contributors present evidence of the ubiquity of discontinuous distributions in ecological and social systems and how their analysis provides insight into complex phenomena. The book is divided into three sections. The first focuses on background material and contrasting views concerning the discontinuous organization of complex systems. The second discusses discontinuous patterns detected in a number of different systems and methods for detecting them, and the third touches on the potential significance of discontinuities in complex systems. Science is still dominated by a focus on power laws, but the contributors to this volume are convinced power laws often mask the interesting dynamics of systems and that those dynamics are best revealed by investigating deviations from assumed power law distributions. In 2008, a grand conference on resilience was held in Stockholm, hosting 600 participants from around the world. There are now three big centers established with resilience, the most recent one being the Stockholm Resilience Center, with others in Australia (an international coral reef center), Arizona State University's new sustainability center focusing on anthropology, and Canada's emerging social sciences and resilience center. Activity continues to flourish in Alaska, South Africa, and the Untied Kingdom, and a new center is forming in Uruguay.

Download or read book Continuities and Discontinuities in Development written by Robert N. Emde and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 423 pages. Available in PDF, EPUB and Kindle. Book excerpt: "Continuities and Discontinuities in Development" was the theme for the Second Biennial DPRG Retreat, a three-day meeting held at Estes Park, Colorado, in June 1982. The meeting was sponsored by the Devel opmental Psychobiology Research Group (DPRG) of the Department of Psychiatry at the University of Colorado School of Medicine. The DPRG is a group of individuals conducting research in many areas of develop ment who meet on a regular basis to present and discuss their work and receive feedback and encouragement. In 1974, this group was awarded an endowment fund by the Grant Foundation, the aims of which were to facilitate the research of young investigators, to encourage new re search, and to provide seed money for collaborative ventures. Much of the work reported in this volume and in the earlier volume from the First DPRG Retreat is the result of that support. In addition to the work of the members of the DPRG, a select group of guests was invited to participate in the meeting and contribute to this volume. The chapters by William Greenough, Jerome Kagan, and Michael Rutter result from the participation of these scholars at the retreat. We would like to acknowledge the support of a number of indi viduals who have been instrumental in supporting the DPRG as a whole, as well as those who contributed directly to the Second Biennial Retreat and to the volume.

This book was released on 2017-01-23 with total page 175 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book focuses on bifurcation theory for autonomous and nonautonomous differential equations with discontinuities of different types – those with jumps present either in the right-hand side, or in trajectories or in the arguments of solutions of equations. The results obtained can be applied to various fields, such as neural networks, brain dynamics, mechanical systems, weather phenomena and population dynamics. Developing bifurcation theory for various types of differential equations, the book is pioneering in the field. It presents the latest results and provides a practical guide to applying the theory to differential equations with various types of discontinuity. Moreover, it offers new ways to analyze nonautonomous bifurcation scenarios in these equations. As such, it shows undergraduate and graduate students how bifurcation theory can be developed not only for discrete and continuous systems, but also for those that combine these systems in very different ways. At the same time, it offers specialists several powerful instruments developed for the theory of discontinuous dynamical systems with variable moments of impact, differential equations with piecewise constant arguments of generalized type and Filippov systems.

This book was released on 2013-03-14 with total page 313 pages. Available in PDF, EPUB and Kindle. Book excerpt: From Catastrophe to Chaos: A General Theory of Economic Discontinuities presents and unusual perspective on economics and economic analysis. Current economic theory largely depends upon assuming that the world is fundamentally continuous. However, an increasing amount of economic research has been done using approaches that allow for discontinuities such as catastrophe theory, chaos theory, synergetics, and fractal geometry. The spread of such approaches across a variety of disciplines of thought has constituted a virtual intellectual revolution in recent years. This book reviews the applications of these approaches in various subdisciplines of economics and draws upon past economic thinkers to develop an integrated view of economics as a whole from the perspective of inherent discontinuity.

Download or read book Stability of Strong Discontinuities in Magnetohydrodynamics and Electrohydrodynamics written by Aleksandr Mikhaĭlovich Blokhin and published by Nova Publishers. This book was released on 2003 with total page 322 pages. Available in PDF, EPUB and Kindle. Book excerpt: This monograph examines multidimensional stability of strong discontinuities (e.g. shock waves) for systems of conservation laws and surveys the author's results for models of ideal magnetohydrodynamics (classical, 'pressure anisotropic', relativistic) and electrohydrodynamics. The primary attention is concentrated on linearised stability analysis, especially on the issue of uniform stability in the sense of the uniform Kreiss-Lopatinski condition. A so-called 'equational' approach based on obtaining, by the dissipative integrals technique, a priori estimates without loss of smoothness for corresponding linearised stability problems in the domains of uniform stability is described. Recent results for ideal models of MHD (classical MHD, 'pressure anisotropic' MHD of Chew, Goldberger and Low, relativistic MHD) and also for a certain non-hyperbolic model are presented as the system of electrohydrodynamics (EHD).

Download or read book Failure Analysis of Shaft with Step and Key way Discontinuities under Combined Loading written by Ashish Kumar Singh and published by Ashish Kumar Singh. This book was released on 2018-05-30 with total page 62 pages. Available in PDF, EPUB and Kindle. Book excerpt: This E-book is a master's dissertation on ‘Failure Analysis of Shaft with Step and Keyway Discontinuities Under Combined Loading ' submitted in May, 2018. In all power transmission elements shaft is almost use in every machine or in every mechanical system. Shaft is a rotating machine element, commonly in circular cross-section, is used to transmit power and rotational motion to other parts such as gears, pulleys, flywheels sprockets and clutches. Various elements, which are used to transmit power from the driving device (motor or engine) are mounted on the shaft with the help of keys. Design of shaft is very important part in mechanical design. In real life, the shaft is subjected to combined loading. A shaft often fails due to the stress concentration in discontinuities areas resulting into large stress values. The most common discontinuities present in the shafts are grooves, slots, shoulders, fillets, holes, thread, etc. Due to presence of these geometrical discontinuities, the stresses are concentrated in discontinuities areas thereby reducing its strength. In the present work, an effort is made to calculate the equivalent stresses and maximum shear stresses developed in shaft due to step and presence of keyways (either single or multiple). These stresses are determined analytically and using finite element analysis (FEA) subjected to combined loading. The modelling of shaft with single keyway (rectangular, square, tapered, semi-circular) is carried out using CREO software and FEA is carried out in ANSYS. Further, the stresses are also determined for shaft with double keyways (rectangular, semi-circular) and stepped shaft with single and double rectangular keyways. Symmetrical and non-symmetrical orientations of double keyways in shaft, is also modelled and analysed. It is concluded that rectangular keyway in solid shaft is best among all the modelled and analyzed keyway in shaft as far as the concern of equivalent and shear stresses and in case of both rectangular and semi-circular keyways, double symmetrical keyways in solid shaft is more suitable than non-symmetrical keyways under combined loading conditions. It is also concluded that double symmetrical keyways in stepped shaft is more suitable than non-symmetrical keyway under combined loading conditions due to less generation of stresses.

Download or read book On Modern Approaches of Hamilton Jacobi Equations and Control Problems with Discontinuities written by Guy Barles and published by Springer Nature. This book was released on 2024-01-30 with total page 569 pages. Available in PDF, EPUB and Kindle. Book excerpt: This monograph presents the most recent developments in the study of Hamilton-Jacobi Equations and control problems with discontinuities, mainly from the viewpoint of partial differential equations. Two main cases are investigated in detail: the case of codimension 1 discontinuities and the stratified case in which the discontinuities can be of any codimensions. In both, connections with deterministic control problems are carefully studied, and numerous examples and applications are illustrated throughout the text. After an initial section that provides a “toolbox” containing key results which will be used throughout the text, Parts II and III completely describe several recently introduced approaches to treat problems involving either codimension 1 discontinuities or networks. The remaining sections are concerned with stratified problems either in the whole space R^N or in bounded or unbounded domains with state-constraints. In particular, the use of stratified solutions to treat problems with boundary conditions, where both the boundary may be non-smooth and the data may present discontinuities, is developed. Many applications to concrete problems are explored throughout the text – such as Kolmogorov-Petrovsky-Piskunov (KPP) type problems, large deviations, level-sets approach, large time behavior, and homogenization – and several key open problems are presented. This monograph will be of interest to graduate students and researchers working in deterministic control problems and Hamilton-Jacobi Equations, network problems, or scalar conservation laws.
