The Eurotherm Committee has chosen Thermal Management of Electronic Systems as the subject of its 29th Seminar, at Delft University of Technology, the Netherlands, 14-16 June 1993. This volume constitutes the proceedings of the Seminar. Thermal Management is but one of the several critical topics in the design of electronic systems. However, as a result of the combined effects of increasing heat fluxes, miniaturisation and the striving for zero defects, preferably in less time and at a lower cost than before, thermal management has become an increasingly tough challenge. Therefore, it is being increasingly recognised that cooling requirements could eventually hamper the technical progress in miniaturisation. It might be argued that we are on the verge of a revolution in thermal management techniques. Previously, a packaging engineer had no way of predicting the tempera tures of critical electronic parts with the required accuracy. He or she* had to rely on full-scale experiments, doubtful design rules, or worst-case estimates. This situation is going to be changed in the foreseeable future. User-friendly software tools, the acquisition and integrity of input and output data, the badly needed training mea sures, the introduction into a concurrent engineering environment: all these items will exert a heavy toll on the flexibility of the electronics industries. Fortunately, this situation is being realised at the appropriate management levels, and the interest in this seminar and the pre-conference tutorials testifies to this assertion.

Darwin2K: An Evolutionary Approach to Automated Design for Robotics is an essential reference tool for researchers, professionals, and students involved in robot design or in evolutionary synthesis, design, and optimization. It is also necessary for users of Darwin2K. Researchers and hobbyists interested in genetic algorithms and artificial life techniques will find the book interesting. The primary purpose of this book is to describe a methodology for using computers to automatically design robots to meet the specific needs of an application. Details of many novel aspects of the methodology are presented, including an evolutionary algorithm for synthesizing and optimizing multiple objective functions, an algorithm for dynamic simulation of arbitrary robots, an extensible software architecture, and a new representation for robots that is appropriate for robot design. The methodology as a whole is significant in terms of its impact on robot design practices, and as a case study in building evolutionary design systems. Individual parts of the systems are also relevant to other areas. For example, the evolutionary algorithm can be used for design and optimization problems other than robotics, and the dynamic simulation algorithm can be used for analysis and simulation of existing robots or as a part of a manual design tool. The book also gives an overview of previous work in automated design of robots, and of evolutionary design in other engineering disciplines.

Crandall's Power Supply Testing Handbook comes into the marketplace at an optimum time. Now, more than ever, there is an urgency for a comprehensive handbook on power supply testing that will fulfill the reference needs of the wide variety of professionals testing power supplies, including designers, manufacturers, purchasers, and field service organizations.

Designing inclusively is no longer an option for companies. It is a business essential. Global populations are getting older, legislation is increasingly prohibitive of unnecessary exclusion and consumer attitudes are beginning to change. Exclusivity is out, inclusivity is in. Research communities the world over are responding to this change in design emphasis. Conferences such as the Cambridge Workshops on Universal Access and Assistive Technology (CWUAAT) offer a forum for researchers from diverse and varied disciplines to bring their perspectives on inclusive design together. This book has been inspired by the second CWUAAT, held in Cambridge, England in March 2004. It contains chapters from an international group of leading researchers in this field. Contributions focus on the following topics: design issues for universal access and assistive technology; enabling computer access and new technologies; and, assistive technology and rehabilitation robotics. This series of conferences is aimed at a broad range of interests, with a general focus on the development of products and solutions. Numerous case studies are used to raise awareness of the challenges faced in developing truly inclusive products, along with examples of good practice for design for a more inclusive world.

The objective of this book is to bring together contributions by eminent researchers from industry and academia who specialize in the currently separate study and application of the key aspects of integration. The state of knowledge on integration and collaboration models and methods is reviewed, followed by an agenda for needed research that has been generated by the participants. The book is the result of a NATO Advanced Research Workshop on "Integration: Information and Collaboration Models" that took place at II Ciocco, Italy, during June 1993. Significant developments and research projects have been occurring internationally in a major effort to integrate increasingly complex systems. On one hand, advancements in computer technology and computing theories provide better, more timely, information. On of users and clients, and the the other hand, the geographic and organizational distribution proliferation of computers and communication, lead to an explosion of information and to the demand for integration. Two important examples of interest are computer integrated manufacturing and enterprises (CIM/E) and concurrent engineering (CE). CIM/E is the collection of computer technologies such as CNC, CAD, CAM. robotics and computer integrated engineering that integrate all the enterprise activities for competitiveness and timely response to changes. Concurrent engineering is the complete life-cycle approach to engineering of products. systems. and processes including customer requirements, design. planning. costing. service and recycling. In CIM/E and in CE, computer based information is the key to integration.

In Finite Element Analysis of Electrical Machines the author covers two-dimensional analysis, emphasizing the use of finite elements to perform the most common calculations required of machine designers and analysts. The book explains what is inside a finite element program, and how the finite element method can be used to determine the behavior of electrical machines. The material is tutorial and includes several completely worked out examples. The main illustrative examples are synchronous and induction machines. The methods described have been used successfully in the design and analysis of most types of rotating and linear machines. Audience: A valuable reference source for academic researchers, practitioners and designers of electrical machinery.

This is a unified collection of important recent results for the design of robust controllers for uncertain systems, primarily based on H8 control theory or its stochastic counterpart, risk sensitive control theory. Two practical applications are used to illustrate the methods throughout.

This book is a compilation of research accomplishments in the fields of modeling, simulation, and their applications, as presented at AsiaSim 2011 (Asia Simulation Conference 2011). The conference, held in Seoul, Korea, November 16-18, was organized by ASIASIM (Federation of Asian Simulation Societies), KSS (Korea Society for Simulation), CASS (Chinese Association for System Simulation), and JSST (Japan Society for Simulation Technology). AsiaSim 2011 provided a forum for scientists, academicians, and professionals from the Asia-Pacific region and other parts of the world to share their latest exciting research findings in modeling and simulation methodologies, techniques, and their tools and applications in military, communication network, industry, and general engineering problems.

Machines will gradually become programmed using computers which have the knowledge of how the objects in the world relate to one another. This book capitalizes on the fact that products which are manufactured can be designed on the computer and that information about the product such as its physical shape provide powerful information to reason about how to develop the process plan for their manufacture. This book explores the whole aspect of using the principles of how parts behave naturally to automatically generate programs that govern how to produce them. The last decade saw tremendous work on how machines can be programmed to perform a variety of tasks automatically. Robotics has witnessed the most work on programming techniques. But it was not until the emergence of the advanced CAD system as a proper source of information representation about objects which are to be manipulated by the robot that it became viable for automated processors to generate robot programs without human interface. It became possible for objects to be described and for principles about how they interact in the world to be developed. The functions which the features designed into the objects serve for the objects can be adequately represented and used in reasoning about the manufacturing of the parts using the robot. This book describes the necessary principles which must be developed for a robot to generate its own programs with the knowledge of the world in the CAD system.

This unique book is the only recent summary presenting a comprehensive, up-to-date and detailed treatment of relay feedback theory, the use of relay feedback for process identification and the use of identified models for general control design in a single volume.

This book is devoted to the optimization of product design and manufacturing systems. It contains selected and carefully composed articles based on presentations given at the IDMME conference held in Nantes, France in 1996. The authors are all involved in cutting-edge research in their respective fields of specialization. The integration of manufacturing constraints and their optimization in the design process is becoming more and more widespread in the development of mechanical products or systems. There is a clear industrial need for these kind of methodologies. Important - but still unsolved - problems are related to the definition of design processes, the choice of optimal manufacturing processes and their integration through coherent methodologies in adapted environments. The main topics addressed in this book are: the optimization and evaluation of the product design process (design methodology, representation and integration of design constraints, design for manufacturing, synthesis of objects with constraints, automatic modelling) the optimization and evaluation of the manufacturing systems (modelling of machining processes, modelling for control and measuring, feature-based manufacturing, CAM and off-line programming) some methodological aspects (computational geometry, simultaneous and concurrent engineering, integrated design and CAD/CAM systems, object modelling, feature-based modelling, design and communication, automatic solvers and optimizers) . Apart from giving a thorough theoretical background, a very important theme is the relation between research and industrial applications. The book is of interest for engineers, researchers and PhD students who are involved in the optimization of design and manufacturing processes.

As Directors of this NATO Workshop we welcome this opportunity to record formally our thanks to the NATO Scientific Affairs Division for making our meeting possible through generous financial support and encouragement. This meeting had two purposes: the first obvious one because we have collected key scientists from East and West together to discuss the latest developments in the design against fatigue for structures and components. The second is less obvious but perhaps in the longer term more important; that is the building of bridges between East and West Europe, bridges cemented in the first place by personal friendship between scientists. Fatigue is the process by which structures subjected to cyclical loads deteriorate. The advent of the industrial revolution and in particular the spread of railways caused this phenomena to be recognised and studied some 150 years ago. Despite intensive efforts over the years and despite a huge increase in our theoretical and practical understanding offatigue, failures still occur causing economic disruption and even loss of life. Some of the reasons lying behind this apparent failure to apply advanced knowledge to everyday engineering were explored during this Workshop. Economic pressures to extend the lives of existing plant are becoming more intense. Therefore of vital importance is the generation of knowledge used to assess the performance of existing structures and machines and to produce guidance on their continued safe operation.

This book compiles all aspects of biomimetics from fundamental principles to current technological advances and their future trends in the development of nanoscale biomaterials and tissue engineering. The scope of this book is principally confined to biologically-inspired design of materials and systems for the development of next generation nanobiomaterials and tissue engineering. The book addresses the state-of-the-art of research progress in the applications of the principles, processes, and techniques of biomimetics. The prospective outcomes of current advancements and challenges in biomimetic approaches are also presented.

Comprehensive treatment of approximation methods for filters and controllers. It is fully up to date, and it is authored by two leading researchers who have personally contributed to the development of some of the methods. Balanced truncation, Hankel norm reduction, multiplicative reduction, weighted methods and coprime factorization methods are all discussed. The book is amply illustrated with examples, and will equip practising control engineers and graduates for intelligent use of commercial software modules for model and controller reduction.

For a long time, quality has been one of industry's main preoccupations. It remains so today. There is some foundation for the statement that there is a 'quality crisis' in Europe, the methods traditionally used in our industries being unable to meet today's demands. Consequently it is essential to look for new directions in which to progress, taking account of the methods for achieving quality that have been developed in recent years. These methods impact on all parts of the industrial enterprise - marketing, manufacturing, research and development, after-sales services. All staff, administrative or technical, are involved. The present book describes the tools that can help anyone who is concerned with the concept of 'total quality'; it will also be a valuable educational aid for students reading for degrees or other qualifications in engineering. P. Lyonnet I General questions and concepts 1 INTRODUCTION: HOW CAN WE ACHIEVE TOTAL QUALITY? This book is concerned with the various techniques and methods of analysis that can be used to ensure total quality in a project. In this first chapter we show the costs that result from not achieving quality, so as to make clear how important a quality-assurance service is to any enterprise. We stress also the involvement of marketing, particularly in laying down specifications for reliability.

The 1980s have witnessed a tremendous growth in the field of computer integrated manufacturing systems. The other major areas of development have been computer-aided design, computer-aided manufacturing, industrial robotics, automated assembly, cellular and modular material handling, computer networking and office automation to name just a few. These new technologies are generally capital intensive and do not conform to traditional cost structures. The net result is a tremendous change in the way costs should be estimated and economic analyses performed. The majority of existing engineering economy texts still profess application of traditional analysis methods. But, as was men tioned above, it is clear that the basic trend in manufacturing industries is itself changing. So it is quite obvious that the practice of traditional economic analysis methods should change too. This book is an attempt to address the various issues associated with non-traditional methods for evaluation of advanced computer-integrated technologies. This volume consists of twenty refereed articles which are grouped into five parts. Part one, Economic Justification Methods, consists of six articles. In the first paper, Soni et at. present a new classification for economic justification methods for advanced automated manufacturing systems. In the second, Henghold and LeClair look at strengths and weaknesses of expert systems in general and more specifically, an ap plication aimed at investment justification in advanced technology. The third paper, by Carrasco and Lee, proposes an enhanced economic methodology to improve the needs analysis, conceptual design and de tailed design activities associated with technology modernization.

This volume originates from two workshops, both focusing on themes that are reflected in the title of the volume. The first workshop took place at Eindhoven University of Technology, April 24-26, 2001, on the occasion of the University granting a doctorate honoris causa to Profes sor John A. Buzacott. The second workshop was held on June 15, 2002 at Cornell University (preceding the annual INFORMSjMSOM Confer ence), honoring John's retirement and his lifetime contributions. Each of the two workshops consisted of about a dozen technical presentations. The objective of the volume, however, is not to simply publish the proceedings of the two workshops. Rather, our objective is to put to gether a select set of articles, each organized into a well-written chapter, focusing on a timely topic. Collected into a single volume, these chapters aim to serve as a useful reference for researchers and practitioners alike, and also as reading materials for graduate courses or seminars.

This essential book documents the latest research progress and key issues affecting SSM software development. With a particular focus on the CAD/CAM environment, it provides a rich source of reference and covers a wide range of topics.

With collaborative product development in a geographically distributed environment and global outsourcing becoming normal for many companies, it is imperative to bring academics, researchers and industrialists together to share research ideas and best practice. The European-Asia Symposium on Engineering Design and Manufacture (EASED 2004) provides such a platform and aims to increase the exchange of ideas and best practice among practitioners and researchers from two major global regions - Europe and Asia. As the manufacturing activities, associated with the design activities in European, American and Japan, are being transferred to Asia, it is timely to organise this International Symposium. The Symposium brings together research experts and industrialists to focus on the issues related to these global changes. This geographical distribution of tasks involved in the whole engineering product realisation process brings great challenge as well as huge benefits. This Symposium provides a platform for academic researchers and industrial practitioners to exchange ideas used to address the challenges presented by this new global economic development. This book presents 75 papers from 185 accepted refereed papers presented at EASED2004.

Pneumatic conveying is one of the most popular methods of handling bulk powdered and granular materials in mining, chemical and agricultural industries.

Its comprehensive worked examples and table ensure that the reader need not consult any other reference material. In this 3rdedition new sections on simulation and modelling have been added, while the use of tomography as a tool for monitoring pneumatic conveying is also covered."

The aim of this book is to provide an account of the state of the art in Com putational Kinematics. We understand here under this term that branch of kinematics research involving intensive computations not only of the nu merical type, but also of symbolic as well as geometric nature. Research in kinematics over the last decade has been remarkably ori ented towards the computational aspects of kinematics problems. In fact, this work has been prompted by the need to answer fundamental questions such as the number of solutions, whether real or complex, that a given problem can admit as well as computational algorithms to support geo metric analysis. Problems of the first kind occur frequently in the analysis and synthesis of kinematic chains, when fine displacements are considered. The associated models, that are derived from kinematic relations known as closure equations, lead to systems of nonlinear algebraic equations in the variables or parameters sought. The algebraic equations at hand can take the form of multivariate polynomials or may involve trigonometric functions of unknown angles.

The book is a valuable research tool-kit for innovators, amateur & professionals alike. Additionally, College & University faculties on Engineering, who organize yearly workshops internationally will find hundreds of novel themes to choose from. Some teachers might just secretly buy this book to introduce out-of-box brain-teasers in classroom to add fizz to normal (at times boring) lecturing. The book can be used as main/add-on textbook towards following courses: (1) Master's degree programs on design innovation worldwide and (2) Senior undergraduate courses in industrial, engineering & product design.

This book is devoted to an investigation of some important problems of mod ern filtering theory concerned with systems of 'any nature being able to per ceive, store and process an information and apply it for control and regulation'. (The above quotation is taken from the preface to 27]). Despite the fact that filtering theory is l'argely worked out (and its major issues such as the Wiener-Kolmogorov theory of optimal filtering of stationary processes and Kalman-Bucy recursive filtering theory have become classical) a development of the theory is far from complete. A great deal of recent activity in this area is observed, researchers are trying consistently to generalize famous results, extend them to more broad classes of processes, realize and justify more simple procedures for processing measurement data in order to obtain more efficient filtering algorithms. As to nonlinear filter ing, it remains much as fragmentary. Here much progress has been made by R. L. Stratonovich and his successors in the area of filtering of Markov processes. In this volume an effort is made to advance in certain of these issues. The monograph has evolved over many years, coming of age by stages. First it was an impressive job of gathering together the bulk of the impor tant contributions to estimation theory, an understanding and moderniza tion of some of its results and methods, with the intention of applying them to recursive filtering problems."

Recently, many new technologies have been developed for engineers to reduce the time required to design and manufacture products in response to rapidly fluctuating market demands. This book addresses a variety of contemporary methodologies, technologies and tools for rapid response manufacturing. The contributions to this volume focus on two major RRM areas: desktop manufacturing and computer and information technologies. Rapid Response Manufacturing is an invaluable resource for research engineers, product design and manufacturing engineers, graduate engineering students, and all those concerned with concurrent engineering.

Analysis of Manufacturing Enterprises presents a unified and systematic treatment of manufacturing enterprises. These enterprises are networks of companies working in partnership. Such networks are a common occurrence in auto, grocery, apparel, computer and other industries; and competition is among enterprises rather than between individual companies. Thus, for these enterprises (global or local) to succeed, there is a need for systematically designing the enterprise-wide value delivery processes such as the order-to-delivery process, supply chain process, and new product development process. This calls for developing systematic analysis methodologies for evaluating the performance of value delivering processes. Analysis of Manufacturing Enterprises fills this vital need. The first part of the book focuses on foundations of manufacturing enterprises: the generic value delivery process, their performance measures and redesign to meet specifications on lead time and defect levels. The second part provides a clear and comprehensive discussion on new product development, order to delivery, and supply chain processes, which are core processes of a manufacturing enterprise. Analysis of Manufacturing Enterprises is an excellent resource for researchers and professionals in the field of manufacturing engineering.
