Most of the reliability literature is directed towards non repairable systems, that is, systems that fail are discarded. This book is mainly dedicated towards providing coverage to the reliability modeling and analysis of repairable systems that are repaired and not replaced when they fail. Most of the equipment - mechanical or otherwise -are repairable and are subjected to maintenance actions- reactive or proactive- at various levels. Maintenance actions are carried out either to preserve a system or to renovate it to a specified functionable state. Maintenance actions are also characterized by the degree (perfect or imperfect) to which a system can be restored, i.e., to an 'as good as new condition' (AGAN), or 'as bad as old condition' (ABAO). Mathematically perfect repair is modeled using a renewal process (RP). Since it represents much idealized situation, this model has restricted applications in the analysis of repairable systems. At the other extreme, the ABAO repair is mathematically modelled using a Non-Homogenous Poisson Process (NHPP). These assumptions are very unrealistic for probabilistic modeling and leads to major distortions in statistical analysis. This unique book provides a comprehensive framework for the modeling and analysis of repairable systems considering both the non- parametric and parametric approaches to deal with the failure data. The book presents MCF based non-parametric approach with several illustrative examples and the generalized renewal process (GRP) based arithmetic reduction of age (ARA) models along with its applications to the systems failure data from aviation industry. The book also covers various multi-criteria decision-making (MCDM), integrated with repairable systems reliability analysis models to provide a much better insight into imperfect repair and maintenance data analysis. A complete chapter on an integrated framework for procurement process is added which will of a great assistance to the readers in enhancing the potential of their respective organization. This book also presents FMEA methods tailored for GRP based repairs. This text has primarily emerged from the industrial experience and research work of the authors. A number of illustrations have been included to make the subject lucid and vivid even to the readers who are relatively new to this area. Besides, various examples have been provided to display the applicability of presented models and methodologies to assist the readers in applying the concepts presented in this book.

A short and entertaining introduction to thermodynamics that uses real-world examples to explain accessibly an important but subtle scientific theory A romantic description of the second law of thermodynamics is that the universe becomes increasingly disordered. But what does that actually mean? Starting with an overview of the three laws of thermodynamics, MacArthur "genius grant" winner R. Stephen Berry explains in this short book the fundamentals of a fundamental science. Readers learn both the history of thermodynamics, which began with attempts to solve everyday engineering problems, and ongoing controversy and unsolved puzzles. The exposition, suitable for both students and armchair physicists, requires no previous knowledge of the subject and only the simplest mathematics, taught as needed. With this better understanding of one science, readers also gain an appreciation of the role of research in science, the provisional nature of scientific theory, and the ways scientific exploration can uncover fundamental truths. Thus, from a science of everyday experience, we learn about the nature of the universe.

The volumes are an edited version of Richard Feynman's lectures, taped and transcribed specifically for the books. It was a rigorous undertaking that resulted in a classic reference work for all physics students, teachers, and researchers. Feynman's effective classroom style remains intact in these volumes, a valuable work by a remarkable educator.The three-volume commemorative issue is hardbound and packaged in a specially-designed slipcase. The lectures are also available in a student paperbound edition.
A versatile toolbox of ideas for creative design solutions. How do things bend? How are things joined? How do things get larger or smaller? When you work creatively in design or architecture, these are the sort of questions that come up again and again-and how you choose to answer them can play a pivotal role in determining the final form of a design project. This book offers a powerful new approach to design and creative visualization, helping you address these key design questions with flexibility and imagination by equipping you with a vital repertoire of design paradigms: basic conceptual and visual ideas that can be applied to all types of design problems. Beginning with fundamental design paradigm concepts, Design Paradigms: * Introduces simple shapes and then explores how more complex forms can accommodate enclosure, attachment, and other common functions * Examines how multiple objects relate to each other and how they can be linked or connected * Looks at multiple functions of a single object, using models that range from a claw hammer to a convertible sofa Bridging the gap between theory and practice, the book discusses how design paradigms can work as conceptual blockbusters in solving design problems. Complete with over 300 illustrations, examples from both natural and man-made environments, and much more, Design Paradigms is a powerful springboard for design exploration-a must-own sourcebook of inspiration for students and professionals in all areas of design, product development, and architecture.
