This book explores the practical implementation of an advanced after-sales management framework devoted to warranty management. The framework is intended for companies producing either standardized or customized products and such a management tool will facilitate organizational improvement and support innovative decision making processes for technical assistance in after-sales services. "After-sales Service of Engineering Industrial Assets" comprises a proposal for a warranty management framework, with an account of the different methods that can be used to improve decision making in the different stages of the after-sales service management process, and strategies for strengthening the structure and foundations of the framework. A review of the fundamental issues and current research topics in warranty management and after sales services is also provided, which is exemplified by a case study. This book is intended for postgraduates, researchers and engineers who are interested in after sales management, assets engineering and warranty management.
Surrogate models expedite the search for promising designs by standing in for expensive design evaluations or simulations. They provide a global model of some metric of a design (such as weight, aerodynamic drag, cost, etc.), which can then be optimized efficiently. "Engineering Design via Surrogate Modelling" is a self-contained guide to surrogate models and their use in engineering design. The fundamentals of building, selecting, validating, searching and refining a surrogate are presented in a manner accessible to novices in the field. Figures are used liberally to explain the key concepts and clearly show the differences between the various techniques, as well as to emphasize the intuitive nature of the conceptual and mathematical reasoning behind them. More advanced and recent concepts are each presented in stand-alone chapters, allowing readers to concentrate on material pertinent to their current design problems, and concepts are clearly demonstrated using simple design problems. This collection of advanced concepts (visualization, constraint handling, coping with noisy data, gradient-enhanced modelling, multi-fidelity analysis and multiple objectives) represents an invaluable reference manual for engineers and researchers active in the area. "Engineering Design via Surrogate Modelling" is complemented by a suite of MATLAB[registered] codes, allowing readers to apply all the techniques presented to their own design problems. By applying statistical modelling to engineering design, this book bridges the gap between the engineering and statistics communities. It will appeal to postgraduates and researchers across the academic engineering design community as well as to practicing design engineers. This title provides an inclusive and practical guide to using surrogates in engineering design. It presents the fundamentals of building, selecting, validating, searching and refining a surrogate model. It guides the reader through the practical implementation of a surrogate-based design process using a set of case studies from real engineering design challenges.
Since the major pioneering of joint replacement surgery more than fifty years ago, much research and progress has been made in the field of arthroplasty with new insights into better materials, types of cement and bone-cell compatible coatings, and a better understanding of the causes of implant failure. With an increasingly ageing population the requirement for arthroplastic surgery is manifest; over 800,000 hips worldwide are replaced each year, and replacement surgery is performed for almost every joint of the body.
The Engineering of Human Joint Replacements covers the design, engineering, production and manufacture of human joint replacements, as well as associated engineering concerns such as surface coatings, orthopedic bone cement, the causes and effects of wear and tear, and rapid prototyping for clinical evaluation. Materials evaluation and selection is discussed, as well as production processes and insertion methods. The author provides an overview of skeletal anatomy and the effects of pain and deterioration in order to put the engineering principles into a medical context. Examples of joint replacements for the most common regions of the body are included, and aspects of clinical studies of these cases are discussed.
? Provides an overview of the engineering materials and processes involved in the manufacture ofÂ Â Â human joint replacements
The Engineering of Human Joint Replacements bridges the divide between engineering and orthopaedic surgery, offering an introductory text to young engineers entering the field, as well as a reference for medical staff who will benefit from an understanding of the materials and methods used in their design, engineering and manufacture.
Increasing numbers of researchers are working in regions experiencing high levels of conflict or crisis, or among populations that have fled violent conflict to become refugees or internally displaced persons. Understanding these conflicts and their aftermath should be shaped not only by the victors and their elite companions but also by the local people whose daily lives become intertwined with the conflict - this 'view from below' is explored in this volume. Conducting rigorous research in these contexts presents a range of ethical, methodological, logistical and security challenges not usually confronted in non-conflict field contexts. This volume compiles lessons learned by experienced field researchers, many of whom have faced demanding situations characterized by violence, distrust and social fragmentation. The authors offer options for studying the situations of people affected by conflict and, by focusing on ethical and security issues, seek ways to safeguard the interests and integrity of the research 'subjects' and of the researchers and their teams.
This book offers a simplified approach to random processes for the non-specialist and advises the reader on how to best predict its behavior, both from raw data and theoretical models. With a premise based on the idea that new techniques are best introduced by specific, low-dimensional examples, rather than attempting to strive for generality at the outset, the mathematics is easier to comprehend and more enjoyable. It distinguishes between the science of extracting statistical information from raw data - e.g., a time series about which nothing is known a priori - and that of analyzing specific statistical models. The former motivates the concepts of statistical spectral analysis (such as the Wiener-Khinchin theorem), and the latter applies and interprets them in specific physical contexts. The Kalman filter is regarded as formidable by most engineers because it is traditionally expostulated in full-blown matrix form. This book, however, introduces it in a very simple scalar context, where the basic strategy is transparent, as is its extension to the general case.
