The study of the kinematics and dynamics of machines lies at the very core of a mechanical engineering background. Although tremendous advances have been made in the computational and design tools now available, little has changed in the way the subject is presented, both in the classroom and in professional references. Fundamentals of Kinematics and Dynamics of Machines and Mechanisms brings the subject alive and current. The author's careful integration of Mathematica software gives readers a chance to perform symbolic analysis, to plot the results, and most importantly, to animate the motion. They get to "play" with the mechanism parameters and immediately see their effects. The downloadable resources contain Mathematica-based programs for suggested design projects. As useful as Mathematica is, however, a tool should not interfere with but enhance one's grasp of the concepts and the development of analytical skills. The author ensures this with his emphasis on the understanding and application of basic theoretical principles, unified approach to the analysis of planar mechanisms, and introduction to vibrations and rotordynamics.

Succinctly formatted for functionality, the book presents: Basic Math Calculations Engineering Math Calculations Production Engineering Calculations Engineering Economics Calculations Ergonomics Calculations Facility Layout Calculations Production Sequencing and Scheduling Calculations Systems Engineering Calculations Data Engineering Calculations Project Engineering Calculations Simulation and Statistical Equations It has been said that engineers make things while industrial engineers make things better. To make something better requires an understanding of its basic characteristics and the underlying equations and calculations that facilitate that understanding. To do this, however, you don't have to be computational experts; you just have to know where to get the computational resources that are needed. This book elucidates the underlying equations that facilitate the understanding required to improve design processes, continuously improving the answer to the age-old question: What is the best way to do a job?

Amidst tightening requirements for eliminating CFC's, HCFC's, halons, and HFC's from use in air conditioning and heat pumps, the search began for replacements that are environmentally benign, non-flammable, and similar to the banned refrigerants in system-level behavior. Refrigerant mixtures are increasingly used as working fluids because they demonstrate desirable thermodynamic, feasibility, and safety characteristics. Vapor Compression Heat Pumps with Refrigerant Mixtures provides the first comprehensive, single-source treatment of working fluid mixtures and their applications in vapor compression systems. The authors explain in detail the thermodynamics of refrigerant mixtures, which is vastly more complex than that of individual refrigerants, as well as the fundamentals of various refrigeration cycles and methods for improving their efficiency.

Among all aspects of engineering, design is the most important step in developing a new product. A systematic approach to managing design issues can only be accomplished by applying mathematical optimization methods. Furthermore, due to the practical issues in engineering problems, there are limitations in using traditional methods. As such, stochastic optimization methods such as differential evolution, simulated annealing, and genetic algorithms are preferable in finding solutions in design optimization problems. This book reviews mechanical engineering design optimization using stochastic methods. It introduces students and design engineers to practical aspects of complicated mathematical optimization procedures, and outlines steps for wide range of selected engineering design problems. It shows how engineering structures are systematically designed. Many new engineering design applications based on stochastic optimization techniques in automotive, energy, military, naval, manufacturing process and fluids-heat transfer, are described in the book. For each design optimization problem described, background is provided for understanding the solutions. There are very few books on optimization that include engineering applications. They cover limited applications, and that too of well-known design problems of advanced and niche nature. Common problems are hardly addressed. Thus, the subject has remained fairly theoretical. To overcome this, each chapter in this book is contributed by at least one academic and one industrial expert researcher.

The finite element and the boundary element methods are the two most important developments in numerical mathematics to occur in this century. Many engineering and mathematics graduate curricula now include a course in boundary element methods. Such a course must cover numerical methods, basic methodology to real problems, and interactive computer usage. Both theory and applications, necessary for applied courses, are available in this new textbook. An Introduction to Boundary Element Methods is logically organized and easy to read. The topics are carefully selected and meticulously presented. Applications are described for use in identifying potential problems and for heat transfer, diffusion equations, linear elasticity, water waves, ocean acoustics, acoustic scattering, aerodynamics, porous media, and simple laminar flows. More than 20 computer subroutines help develop and explain the computational aspect of the subject. Hundreds of figures, exercises, and solved examples supplement text and help clarify important information. The computer programs have been tested on some benchmark problems. Even in single precision the results are more accurate and better than those obtained from available Fortran programs.

Recent advances in technology have permitted the construction of large dams, reservoirs and channels. This progress has necessitated the development of new design and construction techniques, particularly with the provision of adequate flood release facilities. Chutes and spillways are designed to spill large water discharges over a hydraulic structure (e.g. dam, weir) without major damage to the structure itself and to its environment. At the hydraulic structure, the flood waters rush as an open channel flow or free-falling jet, and it is essential to dissipate a very signifi cant part of the flow kinetic energy to avoid damage to the hydraulic structure and its surroundings. Energy dissipation may be realised by a wide range of design techniques. A number of modern developments have demonstrated that such energy dissipation may be achieved (a) along the chute, (b) in a downstream energy dissipator, or (c) a combination of both. The magnitude of turbulent energy that must be dissipated in hydraulic structures is enormous even in small rural and urban structures. For a small storm waterway discharging at a 4 m3/s mm high drop, the turbulent kinetic energy flux per unit time is 120 kW! At a large dam, the rate of energy dissipation can exceed tens to hundreds of gigawatts; that is, many times the energy production rate of nuclear power plants. Many engineers have never been exposed to the complexity of energy dissipator designs, to the physical processes taking place and to the structural challenges. Several energy dissipators, spillways and storm waterways failed because of poor engineering design. It is believed that a major issue affecting these failures was the lack of understanding of the basic turbulent dissipation processes and of the interactions between free-surface aeration and flow turbulence. In that context, an authoritative reference book on energy dissipation in hydraulic structures is proposed here. The book contents encompass a range of design techniques including block ramps, stepped spillways, hydraulic jump stilling basins, ski jumps and impact dissipators.

Andrew Grant Forsyth's photographs show the changing locomotive scene throughout Scotland after the nationalisation of the railways in 1948. Forsyth visited Scotland almost every year, and between 1948 and 1966 he was fortunate to be able to photograph the graceful-looking ex-Great North of Scotland 4-4-0s, the ex-North British Railway 'Glen' and 'Scott' 4-4-0s, the Caledonian 4-4-0s and numerous 0-6-0 and tank locomotive classes remaining from both those companies. Also reproduced are many examples of the London and North Eastern Railway express locomotive fleet, together with locomotives of former London Midland and Scottish Railway and examples of the post-nationalisation Standard locomotives of British Railways. Scottish Steam 1948-1966 is a stunning collection of Andrew Grant Forsyth's photographs, providing a unique insight into a shifting time.

This book deals with two key aspects of the history of steam engines, a cornerstone of the Industrial Revolution, specifically the road that led to its discovery and the process of diffusion of the early steam engines. The first part of the volume outlines the technological and scientific developments which took place between the 16th and 18th centuries, proving critical for the invention of this strategic technology. The most important question addressed is why did England come up with this innovation first as opposed to other countries (e.g., France, Italy), which were more advanced in terms of knowledge pertinent to it. The second part of the volume traces the process of diffusion of the early steam engines, the Newcomen model, through to 1773, the year prior to the first commercial application of the second generation of steam engines (the Watt model). The process of diffusion is quantified on the basis of a novel method before proceeding with a discussion of the main determinants of this process. Kitsikopoulos pulls together a large amount of relevant evidence found in primary sources and more technically oriented literature which is often ignored by economic historians. This book will be of interest to economic historians and historians of technology.
