This small hardback title, the seventh in Coxmoor's Machine & Systems Condition Monitoring Series, is aimed at engineers and maintenance professionals. The book introduces its subject at an understandable level, touching on the basic theory and concepts, available equipment, and practical issues relevant to the engineer, as well as providing several case studies. The aim of this book is to explain the principles and techniques of noise generation and measurement, and to indicate the methods available for using noise signals as the basis of a tool for condition monitoring. Among the subjects covered are basic concepts and terminology; practical difficulties encountered when measuring noise; the range of noise, measuring, analysis, monitoring, and recording equipment that is available, and actual case studies illustrating the successful application of noise measurement.
Despite increasingly rapid technological innovation and diffusion, we know surprisingly little about the social and human processes involved. Why have some spread so successfully, while, for example, so many agricultural innovations in the Third World have been failures? What are the consequences of top-down diffusion strategies? Are there downsides to leaving the whole process to the private sector and in particular to giant high-tech corporations? If users are democratically involved in technological adaptation and adoption, won't the result often be both better technologies and their more rapid adoption? These are some of the questions explored in this account of successes and failures in technological development and diffusion. The author's examples come from both industrialized and developing countries, covering such subjects as agricultural appliances, wind turbines, high-yielding seeds, and the Linux computer operating system.
In technical processes involving liquids, it can be necessary to measure their thermophysical properties (thermal conductivity, thermal diffusivity, and specific heat) efficiently and effectively. The authors believe that conventional methods and devices for measuring thermophysical properties are not adequate for measuring liquid in flow conditions. They assert that laminar flow methods and devices provide advantages over conventional TPP measurement methods and devices for assessing liquid flow. Following a review of traditional practices, they present information about and examples of laminar flow methods and measuring devices. Most of the references cited are from Russian research.
Applied Optimization With Matlab Programming
Combining a formal presentation of classical methods of design optimization with detailed instruction in the application of these methods using Matlab, this book introduces the symbolic, numerical, and graphic features of Matlab. It also integrates this powerful combination in the translation of many algorithms into applied optimization techniques with animation. The book focuses on real-world optimization techniques and covers all areas of optimization, including linear, nonlinear, discrete, and global. The author includes examples from many disciplines and presents practical, open-ended design problems. This volume is directed at senior undergraduates and graduate students in engineering, but may be used by design engineers in all fields of endeavor..
The product of a collaboration among four leading scientists in academic research and industry, this book is a comprehensive text and reference work on scientific computing. This new version incorporates completely new C++ versions of the more than 300 Numerical Recipes second edition routines recognized as the most accessible and practical basis for scientific computing in addition to including the full contents of Numerical Recipes in C. The authors' approach to C++ preserves the efficient execution C users expect, while employing a clear, object-oriented interface to the routines. Tricks and tips for scientific computing are included. The book proceeds from mathematical and theoretical considerations to actual practical computer routines.
Mechatronics has evolved into a way of life in engineering practice and pervades virtually every aspect of the modern world. As the synergistic integration of mechanical, electrical, and computer systems, the successful implementation of mechatronic systems requires the integrated expertise of specialists from each of these areas. This imposing volume, in more than 60 articles authored by academics and practitioners, moves from the history of mechatronics through the underlying theories, systems, processes, and practice to perspective on the field's current and future trends. There are six sections: an overview of mechatronics, physical system modeling, sensors and actuators, systems and controls, computers and logic systems, and software and data acquisition. The book, a co-publication of the Instrumentation, Systems, and Automation Society, contains numerous formulas, data tables, and illustrations.
The authors, veterans of the environmental and air pollution wars while teaching at Massachusetts colleges, offer their views of a critical problem in urban-industrial societies: the worldwide growth of energy use and the destructive relationship between this energy use and environmental degradation. This text provides the scientific and technological background for understanding how the ever-increasing use of energy threatens the natural environment, and how this threat could be mitigated by more efficient use of conventional energy sources and their replacement by renewable energy sources. Designed for upper-level undergraduates and first-year graduate students, this book also addresses energy and environmental professionals. Among the topics covered are: global energy use and supply; thermodynamic principles of energy conversion; electrical energy generation, transmission, and storage; fossil- and nuclear-fueled power plants; renewable energy; transportation, and global warming. Each chapter concludes with a bibliography.
The sphere, we are told, is the foundation of the five Platonic and 13 Archimedean solids, which include the cube, the octahedron, and the tongue-twisting icosidodecahedron. These 18 shapes are the building blocks of three-dimensional space, central to architecture, chemistry, and atomic physics. In this unusual, pint-size package rich with illustrations, geometer and artist Daud Sutton shows the elegant simplicity in the relationships among these beautiful forms that inspire anyone interested in science, design, and mathematics.
