This book was released on 2016-07-27 with total page 130 pages. Available in PDF, EPUB and Kindle. Book excerpt: This thesis introduces novel and significant results regarding the analysis and synthesis of positive systems, especially under l1 and L1 performance. It describes stability analysis, controller synthesis, and bounding positivity-preserving observer and filtering design for a variety of both discrete and continuous positive systems. It subsequently derives computationally efficient solutions based on linear programming in terms of matrix inequalities, as well as a number of analytical solutions obtained for special cases. The thesis applies a range of novel approaches and fundamental techniques to the further study of positive systems, thus contributing significantly to the theory of positive systems, a “hot topic” in the field of control.
Download or read book Positive Systems Theory and Applications written by Luca Benvenuti and published by Springer Science & Business Media. This book was released on 2003-07-25 with total page 428 pages. Available in PDF, EPUB and Kindle. Book excerpt: The proceedings of the First Multidisciplinary International Symposium on Positive Systems Theory and Applications (POSTA 2003) held in Rome, Italy, August 28-30, 2003. Positive Systems are systems in which the relevant variables assume nonnegative values. These systems are quite common in applications where variables represent positive quantities such as populations, goods, money, time, data packets flowing in a network, densities of chemical species, probabilities, etc. The aim of the symposium was to join together researchers working in the different areas related to positive systems such as telecommunications, economy, biomedicine, chemistry and physics in order to provide a multidisciplinary forum where they have the opportunity to exchange ideas and compare results in a unifying framework.
Download or read book Towards Positive Systems of Child and Family Welfare written by Nancy Freymond and published by University of Toronto Press. This book was released on 2006-05-20 with total page 369 pages. Available in PDF, EPUB and Kindle. Book excerpt: The need for services that respond to the ‘maltreatment’ of children and to the struggles of families is at the core of social service systems in all developed nations. While these child and family welfare systems confront similar problems and incorporate common elements, there are substantial differences in philosophy, organization, and operation across international settings and models. In this new collection of essays, Nancy Freymond and Gary Cameron have brought together some of the finest international minds to provide an original and integrated discussion of child protection, family service, and community caring models of child and family welfare. The volume not only examines child protection and family service approaches within Western nations – including Canada, the United States, England, the Netherlands, France, and Sweden – it is also the first comparative study to give equal attention to Aboriginal community caring models in Canada and New Zealand. The comparisons made by the essays in this volume allow for a consideration of constructive and feasible innovations in child and family welfare and contribute to an enriched debate around each system. This book will be of great benefit to the field for many years to come.

Download or read book Moving Toward Positive Systems of Child and Family Welfare written by Gary Cameron and published by Wilfrid Laurier Univ. Press. This book was released on 2007-04-19 with total page 409 pages. Available in PDF, EPUB and Kindle. Book excerpt: Faced with rapidly changing social and economic conditions, service professionals, policy developers, and researchers have raised significant concerns about the Canadian child welfare system. This book draws inspiration from experiences with three broad, international child welfare paradigms—child protection, family service, and community healing/caring (First Nations)—to look at how specific practices in other countries, as well as alternative experiments in Canada, might foster positive innovations in the Canadian child welfare approach. Foundational values and purposes, systems design and policy, and organization and management are discussed, as are front-line service delivery, service provider work environments, and the realities of daily living for families. Informed by recent research, the contributors provide clear directions for policy, administration, and service-delivery reforms. Informing policy debates addressing child maltreatment and family welfare, this book will serve as a vital resource for managers, service providers, professionals, and students in the fields of social work, child and youth care, family studies, psychology, and special education.

Download or read book Positive Feedback in Natural Systems written by Donald L. DeAngelis and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 292 pages. Available in PDF, EPUB and Kindle. Book excerpt: Cybernetics, a science concerned with understanding how systems are regulated, has reflected the preoccupations of the century in which it was born. Regulation is important in twentieth century society, where both machines and social organizations are complex. Cybernetics focused on and became primarily associated with the homeostasis or stability of system behavior and with the negative feedbacks that stabilize systems. It paid less attention to the processes opposite to negative feedback, the positive feedback processes that act to change systems. We attempt to redress the balance here by illustrating the enormous importance of positive feedbacks in natural systems. In an article in the American Scientist in 1963, Maruyama called for increased attention to this topic, noting that processes of change could occur when a "deviation in anyone component of the system caused deviations in other components that acted back on the first component to reinforce of amplify the initial deviation." The deviation amplification is the result of positive feedback among system components. Maruyama demonstrated by numerous examples that the neglect of such processes was unjustified and suggested that a new branch of cybernetics, "the second cybernetics," be devoted to their study.

Download or read book Positive Dynamical Systems in Discrete Time written by Ulrich Krause and published by Walter de Gruyter GmbH & Co KG. This book was released on 2015-11-27 with total page 429 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book provides a systematic, rigorous and self-contained treatment of positive dynamical systems. A dynamical system is positive when all relevant variables of a system are nonnegative in a natural way. This is in biology, demography or economics, where the levels of populations or prices of goods are positive. The principle also finds application in electrical engineering, physics and computer sciences. "The author has greatly expanded the field of positive systems in surprising ways." - Prof. Dr. David G. Luenberger, Stanford University(USA)
Download or read book Systems Leadership written by Ian Macdonald and published by Routledge. This book was released on 2018-05-24 with total page 713 pages. Available in PDF, EPUB and Kindle. Book excerpt: The new edition of this influential and bestselling book is concerned with how people come together to achieve a productive purpose. Survival and success in business and social terms have always depended upon our ability to form and sustain social organisations. People have a deep need to be creative and to belong. By creating positive organisations we can fulfil these needs and build a worthwhile society. One of the failures of organisations is precisely the lack of efficient and effective social organisation, which is what this whole book is about. Poor social organisation, including poor leadership, are major drivers of poor productivity and lead people to give up or retreat into a minimalist approach of just doing what is needed to get by and survive. The authors provide a language for developing, discussing, thinking and working with propositions about organisations and management. They do not tell you what decision to make but rather present tools to help you consider, analyse and predict the consequences of your decisions. This new edition is much broader in its application areas – public, private and not-for-profit sectors. It contains new models and propositions with regard to types of social organisation, domains of work and the nature and use of authority. It contains a range of new case studies, and throughout looks at how these ideas can be used to achieve an organisation’s purpose while encouraging creative working. It is not a book about fads or fashion but an integrated approach that offers the user the benefit of foresight.

Download or read book The Realization Problem for Positive and Fractional Systems written by Tadeusz Kaczorek and published by Springer Science & Business Media. This book was released on 2014-02-06 with total page 599 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book addresses the realization problem of positive and fractional continuous-time and discrete-time linear systems. Roughly speaking the essence of the realization problem can be stated as follows: Find the matrices of the state space equations of linear systems for given their transfer matrices. This first book on this topic shows how many well-known classical approaches have been extended to the new classes of positive and fractional linear systems. The modified Gilbert method for multi-input multi-output linear systems, the method for determination of realizations in the controller canonical forms and in observer canonical forms are presented. The realization problem for linear systems described by differential operators, the realization problem in the Weierstrass canonical forms and of the descriptor linear systems for given Markov parameters are addressed. The book also presents a method for the determination of minimal realizations of descriptor linear systems and an extension for cone linear systems. This monographs summarizes recent original investigations of the authors in the new field of the positive and fractional linear systems.
