Stochastic Modelling and Control - Mark Davis - Bog - Springer - Plusbog.dk

Stochastic Modelling and Control - Mark Davis - Bog - Springer - Plusbog.dk

This book aims to provide a unified treatment of input/output modelling and of control for discrete-time dynamical systems subject to random disturbances. The results presented are of wide applica­ bility in control engineering, operations research, econometric modelling and many other areas. There are two distinct approaches to mathematical modelling of physical systems: a direct analysis of the physical mechanisms that comprise the process, or a ''black box'' approach based on analysis of input/output data. The second approach is adopted here, although of course the properties ofthe models we study, which within the limits of linearity are very general, are also relevant to the behaviour of systems represented by such models, however they are arrived at. The type of system we are interested in is a discrete-time or sampled-data system where the relation between input and output is (at least approximately) linear and where additive random dis­ turbances are also present, so that the behaviour of the system must be investigated by statistical methods. After a preliminary chapter summarizing elements of probability and linear system theory, we introduce in Chapter 2 some general linear stochastic models, both in input/output and state-space form. Chapter 3 concerns filtering theory: estimation of the state of a dynamical system from noisy observations. As well as being an important topic in its own right, filtering theory provides the link, via the so-called innovations representation, between input/output models (as identified by data analysis) and state-space models, as required for much contemporary control theory.

Muslim Merit-making in Thailand's Far-South - Christopher M. Joll - Bog - Springer - Plusbog.dk

Muslim Merit-making in Thailand's Far-South - Christopher M. Joll - Bog - Springer - Plusbog.dk

This volume provides an ethnographic description of Muslim merit-making rhetoric, rituals and rationales in Thailand''s Malay far-south. This study is situated in Cabetigo, one of Pattani''s oldest and most important Malay communities that has been subjected to a range of Thai and Islamic influences over the last hundred years. The volume describes religious rhetoric related to merit-making being conducted in both Thai and Malay, that the spiritual currency of merit is generated through the performance of locally occurring Malay adat , and globally normative amal ''ibadat. Concerning the rationale for merit-making, merit-makers are motivated by both a desire to ensure their own comfort in the grave and personal vindication at judgment, as well as to transfer merit for those already in the grave, who are known to the merit-maker. While the rhetoric elements of Muslim merit-making reveal Thai influence, its ritual elements confirm the local impact of reformist activism.

Ecological Economics - Stanislav E. Shmelev - Bog - Springer - Plusbog.dk

Ecological Economics - Stanislav E. Shmelev - Bog - Springer - Plusbog.dk

In a concise and crisp manner, this book presents the state of the art in ecological economics, an interdisciplinary field focused on the analysis of sustainability of global, national and regional economic systems. An elegant guide, the book offers a range of cutting edge methods used in sustainability research including multicriteria decision aid (MCDA), input-output analysis, and life cycle analysis. This book is packed with references for students with some background in economics, environmental science or mathematics who aim to develop the analytical skills required for redirecting our development path towards sustainability in government, international organisations, academia, non-profit sector and business. As such, the book is primarily aimed at MSc and first year PhD students reading for degrees in Environmental Change and Management, Ecological Economics, Environmental Management, Philosophy, Politics and Economics, and those taking part in similar programmes. The book strives to develop the idea that a significant adjustment of the current economic theories is required, an idea supported by the emerged world economic crisis, the climatic and biodiversity crisis the world is currently facing and the enormously slow progress that has been made in the field of reorientation of the global economy towards sustainability. The practical case studies provided focus on the most pressing topics of today, and the book adopts a positive approach for problem solving and strategic development, which is aimed at educating the future decision makers and business leaders.

Handbook of Energy for World Agriculture - B.a. Stout - Bog - Springer - Plusbog.dk

Handbook of Energy for World Agriculture - B.a. Stout - Bog - Springer - Plusbog.dk

Adequate food supplies and a reasonable quality of life require energy~both noncommercial and commercial forms. This book is intended to be a reference for individuals who want a comprehensive overview of energy for agriculture, many of whom are located in remote areas with limited library resources. The purpose is to put energy for agriculture in perspective by presenting numerous national and regional examples of energy usage. Since the early 1970s, world petroleum prices have fluctuated from $3/barrel to more than $40/barrel in 1981 and then back to less than a half of the peak price today. Commercial energy is expensive at any price for rural villagers in developing countries, and energy prices in these countries do not necessarily correspond with world prices. For example, diesel fuel prices in some developing countries have increased, while world oil prices have decreased. The rural sector of developing countries depends heavily on noncommercial energy sources. Availability of noncommercial energy is highly site-specific. This book deals extensively with noncommercial energy~its sources, the technologies for converting energy to more useful gaseous and liquid forms, and its ultimate end uses. Chapter I is an introduction and overview. It emphasizes the essential nature of energy to supplement the limited work output of human beings. Chapter II describes energy use in world agriculture with particular emphasis on fertilizer, machinery, and irrigation. It tabulates cereal grain yields as related to commercial energy input for various regions. Chapter III presents numerous national and regional illustrations of energy use.
