An expanded new edition of the bestselling system dynamics book using the bond graph approach A major revision of the go-to resource for engineers facing the increasingly complex job of dynamic systems design, System Dynamics, Fifth Edition adds a completely new section on the control of mechatronic systems, while revising and clarifying material on modeling and computer simulation for a wide variety of physical systems. This new edition continues to offer comprehensive, up-to-date coverage of bond graphs, using these important design tools to help readers better understand the various components of dynamic systems. Covering all topics from the ground up, the book provides step-by-step guidance on how to leverage the power of bond graphs to model the flow of information and energy in all types of engineering systems. It begins with simple bond graph models of mechanical, electrical, and hydraulic systems, then goes on to explain in detail how to model more complex systems using computer simulations. Readers will find: New material and practical advice on the design of control systems using mathematical models New chapters on methods that go beyond predicting system behavior, including automatic control, observers, parameter studies for system design, and concept testing Coverage of electromechanical transducers and mechanical systems in plane motion Formulas for computing hydraulic compliances and modeling acoustic systems A discussion of state-of-the-art simulation tools such as MATLAB and bond graph software Complete with numerous figures and examples, System Dynamics, Fifth Edition is a must-have resource for anyone designing systems and components in the automotive, aerospace, and defense industries. It is also an excellent hands-on guide on the latest bond graph methods for readers unfamiliar with physical system modeling.
Scenic rural communities across the nation and around the world have been transformed as they have shifted away from extractive industries such as agriculture, mining, and forestry and toward recreation-based development relying on tourism, vacation homes, and retirees. These communities have built new economies and identities based on local natural resources and are highly dependent on the natural environment. With these changes have come new questions: Do retirees and seasonal residents fit into their new surroundings? Do longtime and new residents share the same values and visions for the future? Do diverse community members disagree about how to manage their forest and water resources? Condos in the Woods explores how these issues are reshaping community structure, employment, and inhabitants' attitudes toward their environment in the Northwoods. Looking at trends from the 1970s to the present, this work moves from the national scale to the Pine Barrens region in northwestern Wisconsin and examines the approaches of residents to the management of their natural resources. At the heart of this story, the authors find that despite the diverse makeup of such communities, residents share many common goals and values and display more successful integration than previously expected. "Makes a major contribution linking and expanding beyond an array of research on the question: What does the growing dominance of seasonal home ownership and use mean for the communities of northern Wisconsin?"—Susan I. Stewart, USDA Forest Service, Northern Research Station
This volume is a cogent empirical analysis of the interplay between a region’s natural amenities and its socioeconomic evolution. It focuses on the rural sectors of America’s Intermountain West region, which lies between the Cascades and Sierra Nevada mountains to the west and the Rocky Mountains to the east. Coherently structured and meticulously detailed, it adds much to our understanding of the ways an area’s forests, lakes, mountains, parkland and historic attractions affect residents’ sense of well-being as well as the sociodemographic and economic changes they experience. The book examines patterns of growth and change linked to the emergence of ‘New West’ conditions, assessing their implications for the wider community as well as discussing the impact these trends could have on the consumption of natural resources. It also points to ways in which communities and their development can be managed sustainably. The tight geographical focus of this valuable resource ensures a depth of analysis which can be applied to similar regions worldwide. Based on a large-scale, random-sample survey of both full-time and seasonal residents, it provides a much-needed overview of the macro-level economic, demographic, and social transformations affecting rural communities in America. As such, the book has relevance for all researchers concerned with rural development, the changes impacting rural landscapes, and natural resource management.
In this thoughtful collection of essays edited by Debra J. Salazar and Donald K. Alper, forest policy in the U.S. Pacific Northwest and British Columbia is examined in a binational context. While US and Canadian forest policy and forest management approaches differ, the two countries face similar challenges and conflicts. Contributors discuss the evolution of forest exploitation, the response of timber companies to U.S. federal environmental regulations, sovereignty for First Nations communities, and the reshaping of the political economy of forests by global forces on both sides of the border. Groups usually ignored in the forest policy debate -- such as First Nations peoples, workers in the emerging non-forest economy, and citizen activists -- are also given voice in this fascinating compilation.
Large deviations for an exchangeable system of reversible diffusions in [double-struck]R[superscript italic]d are investigated in the limit when the number of particles tends to infinity with the objective of providing a methodology to study dynamical phase transitions, tunnelling and metastability for the class of mean field models in statistical physics.
Explains and resolves the electromagnetic compatibility challenges faced by engineers in transportation and communications This book is a mathematically-rich extension of courses required to maintain the Federal Communications Commission (FCC), the Canadian Standards Association (CSA), and the European Union certifications. The text provides an in-depth study of the electromagnetic compatibility (EMC) issues related to specific topics in transportation and communications, including Light Rail Transit, shadow effects, and radio dead spots, through the analysis of real-world case studies in the United States and Europe. The author provides Cartesian, cylindrical, and spherical solutions that can be applied to Maxwell's and Wave Equations. The book covers topics such as SCADA Systems, shielding, and complexities of radio frequencies and their effect on communication houses. The author also provides information for alternative industries to apply the solutions from the case studies and background content to their own professions. Presents a series of over twenty real-world case studies related to EMC in transportation and communications Covers power line radiation, shadow effects on subway cars, train control systems, and edge distortions Includes the OATS testing method and Department of Transportation (DOT) test Provides access to a companion website housing power point slides and additional appendices Electromagnetic Compatibility: Analysis and Case Studies in Transportation is a reference for practicing engineers involved in transportation and communications, as well as post-graduate engineering students studying transportation and communications in engineering.

MMIX is a RISC computer designed by Don Knuth to illustrate machine-level aspects of programming. In the author's book series "The Art of Computer Programming", MMIX replaces the 1960s-style machine MIX. A particular goal in the design of MMIX was to keep its machine language simple, elegant, and easy to learn. At the same time, all of the complexities needed to achieve high performance in practice are taken into account. This book constitutes a collection of programs written in CWEB that make MMIX a virtual reality. Among other utilities, an assembler converting MMIX symbolic files to MMIX objects and two simulators executing the programs in given object files are provided. The latest version of all programs can be downloaded from MMIX's home page. The book provides a complete documentation of the MMIX computer and its assembly language. It also presents mini-indexes, which make the programs much easier to understand. A corrected reprint of the book has been published in August 2014, replacing the version of 1999.
