Product design significantly influences product cost and quality, as well as market share and profitability of a firm. Design projects often involve many people belonging to different functional areas and in many organizations several design projects may be under way at the same time. Due to this complexity, management of design has given rise to a rich set of research problems in management and engineering. In this volume, design is considered as the planning and specification activity prior to fabrication. Design determines what products will be produced, how they will be produced, and when they will be introduced into the market. The quality of the products and the speed with which they are developed are significantly affected by the design process. The design process by which a product is developed is determined by the managerial and engineering practices, tools and techniques. This book presents engineering and management perspectives on design. Topics covered include: Decomposition of product development projects; Tools and techniques for preliminary evaluation of designs; Interface between design and manufacturing, assembly and distribution; Design information flows, and Determination of the scope, timing and duration of projects, and the allocation of resources.

The manufacture and processing of textiles is a complex and essential industry requiring many diverse skills to ensure profitability. New products are continually being developed, and reflect the energy and innovation of those working in the field. This book focuses on the technological aspects of the chemical processing oftextiles, and on the modifications necessary for specific work environments. Coverage ranges from fibre structure and its relationship to tensile properties, textile aesthetics, comfort physiology, and end-use performance, through to the effect of domestic processing by the consumer on the textile product. The industry is constantly under environmental pressure, and the book examines the nature of environmental control and the development of alternative technology to produce less environmental impact. In order to provide a balanced view of the current situation, authors have been drawn from academia, research institutes and industry to produce a text that will be useful to both industrial readers and university students. In conclusion I would like to thank the authors for their dedication and their contributions.

It is also an important text for students of applied mathematics, mechanical engineering, optimal control and operations research.

Process planning determines how a product is to be manufactured and is therefore a key element in the manufacturing process. It plays a major part in determining the cost of components and affects all factory activities, company competitiveness, production planning, production efficiency and product quality. It is a crucial link between design and manufacturing. There are several levels of process planning activities. Early in product engineering and development, process planning is responsible for determining the general method of production. The selected general method of production affects the design constraints. In the last stages of design, the designer has to consider ease of manufacturing in order for it to be economic. The part design data is transferred from engineering to manufacturing and process planners develop the detailed work package for manufacturing a part. Dimensions and tolerances are determined for each stage of processing of the workpiece. Process planning determines the sequence of operations and utilization of machine tools. Cutting tools, fixtures, gauges and other accessory tooling are also specified. Feeds, speeds and other parameters of the metal cutting and forming processes are determined.

The strong interaction between the demand for increasing chip functionality and data-processing speeds, and technological trends in the integrated circuit industry, like e.g. shrinking device geometry, growing chip area and increased transistor switching speeds, cause a huge increase in power dissipation for deep sub-micron digital CMOS circuits. Low-Power Deep Sub-micron CMOS Logic, Sub-threshold Current Reduction classifies all power dissipation sources in digital CMOS circuits and provides for a systematic approach of power reduction techniques. A clear distinction has been made between power dissipated to perform a calculation in a certain time frame, i.e. functional power dissipation, and power dissipated even when a circuit is idle, i.e. parasitical power dissipation. The threshold voltage level forms an important link between the functional and the parasitical power dissipation. Since for high data-processing speeds the threshold voltage needs to be low, whereas for low sub-threshold leakage currents it needs to be high. The latter is extremely important for battery operated circuits in standby modes.Therefore, a separate classification of sub-threshold current reduction techniques is presented showing existing and new circuit topologies. Low-Power Deep Sub-micron CMOS Logic, Sub-threshold Current Reduction is a valuable book for researchers, designers as well as students in the field of low-power digital design. Power dissipation is discussed from a fundamental, quantum mechanical and a practical point of view. Theory is accompanied with practical circuit implementations and measurement results.

Intelligent/smart systems have become common practice in many engineering applications. On the other hand, current low cost standard CMOS technology (and future foreseeable developments) makes available enormous potentialities. The next breakthrough will be the design and development of "smart adaptive systems on silicon" i.e. very power and highly size efficient complete systems (i.e. sensing, computing and "actuating" actions) with intelligence on board on a single silicon die. Smart adaptive systems on silicon will be able to "adapt" autonomously to the changing environment and will be able to implement "intelligent" behaviour and both perceptual and cognitive tasks. At last, they will communicate through wireless channels, they will be battery supplied or remote powered (via inductive coupling) and they will be ubiquitous in our every day life.

Although many books deal with research and engineering topics (i.e. algorithms, technology, implementations, etc.) few of them try to bridge the gap between them and to address the issues related to feasibility, reliability and applications. Smart Adaptive Systems on Silicon, though not exhaustive, tries to fill this gap and to give answers mainly to the feasibility and reliability issues.

Smart Adaptive Systems on Silicon mainly focuses on the analog and mixed mode implementation on silicon because this approach is amenable of achieving impressive energy and size efficiency. Moreover, analog systems can be more easily interfaced with sensing and actuating devices.

This book is concerned with two intimately related topics of metaphysics: the identity of entities and the foundations of classification. What it adds to previous discussions of these topics is that it addresses them with respect to human-made entities, that is, artefacts. As the chapters in the book show, questions of identity and classification require other treatments and lead to other answers for artefacts than for natural entities. These answers are of interest to philosophers not only for their clarification of artefacts as a category of things but also for the new light they may shed on these issue with respect to to natural entities. This volume is structured in three parts. The contributions in Part I address basic ontological and metaphysical questions in relation to artefact kinds: How should we conceive of artefact kinds? Are they real kinds? How are identity conditions for artefacts and artefact kinds related? The contributions in Part II address meta-ontological questions: What, exactly, should an ontological account of artefact kinds provide us with? What scope can it aim for? Which ways of approaching the ontology of artefact kinds are there, how promising are they, and how should we assess this? In Part III, the essays offer engineering practice rather than theoretical philosophy as a point of reference. The issues addressed here include: How do engineers classify technical artefacts and on what grounds? What makes specific classes of technical artefacts candidates for ontologically real kinds, and by which criteria?

There currently exists an abundance of materials selection advice for designers suited to solving technical product requirements. In contrast, a stark gap can be found in current literature that articulates the very real personal, social, cultural and economic connections between materials and the design of the material world. "In Materials Experience: fundamentals of materials and design," thirty-four of the leading academicians and experts, alongside 8 professional designers, have come together for the first time to offer their expertise and insights on a number of topics common to materials and product design. The result is a very readable and varied panorama on the world of materials and product design as it currently stands.
Contributions by many of the most prominent materials experts and designers in the field today, with a foreword by Mike Ashby.The book is organized into4 main themes: sustainability, user interaction, technology and selection.

Between chapters, you willfind theresults of interviews conducted with internationally known designers. These designer perspectives will provide a time out from the academic articles, with emphasis placed on fascinating insights, product examples and visuals. "

This book studies methods for a robust design of rotors against self-excited vibrations. The occurrence of self-excited vibrations in engineering applications if often unwanted and in many cases difficult to model. Thinking of complex systems such as machines with many components and mechanical contacts, it is important to have guidelines for design so that the functionality is robust against small imperfections. This book discusses the question on how to design a structure such that unwanted self-excited vibrations do not occur. It shows theoretically and practically that the old design rule to avoid multiple eigenvalues points toward the right direction and have optimized structures accordingly. This extends results for the well-known flutter problem in which equations of motion with constant coefficients occur to the case of a linear conservative system with arbitrary time periodic perturbations.

Various structures, such as buildings, bridges, and paved roads play an important role in our lives. However, these construction projects require large expenditures. Designing infrastructure cost-efficiently while satisfying all necessary design constraints is one of the most important and difficult tasks for a structural engineer. Traditionally, mathematical gradient-based optimization techniques have been applied to these designs. However, these gradient-based methods are not suitable for discrete design variables such as factory-made cross sectional area of structural members. Recently, researchers have turned their interest to phenomenon-mimicking optimization techniques because these techniques have proved able to efficiently handle discrete design variables. One of these techniques is harmony search, an algorithm developed from musical improvisation that has been applied to various structural design problems and has demonstrated cost-savings. This book gathers all the latest developments relating to the application of the harmony search algorithm in the structural design field in order for readers to efficiently understand the full spectrum of the algorithm's potential and to easily apply the algorithm to their own structural problems. This book contains six chapters with the following subjects: standard harmony search algorithm and its applications by Lee; standard harmony search algorithm for steel frame design by Degertekin; adaptive harmony search algorithm and its applications by Saka and Hasancebi; harmony particle swarm algorithm and its applications by Li and Liu; hybrid algorithm of harmony search, particle swarm & ant colony for structural design by Kaveh and Talatahari; and parameter calibration of viscoelastic and damage functions by Mun and Geem."

This volume, Mechanical Design: Theory and Methodology, has been put together over the past four years. Most of the work is ongoing as can be ascertained easily from the text. One can argue that this is so for any text or monograph. Any such book is only a snapshot in time, giving information about the state of knowledge of the authors when the book was compiled. The chapters have been updated and are representative of the state of the art in the field of design theory and methodology. It is barely over a decade that design as an area of study was revived, mostly at the behest of industry, government, and academic leaders. Profes sor Nam Suh, then the head of the Engineering Directorate at the National Science Foundation, provided much of the impetus for the needed effort. The results of early work of researchers, many of whom have authored chapters in this book, were fundamental in conceiving the ideas behind Design for X or DFX and concurrent engineering issues. The artificial intelli gence community had a strong influence in developing the required com puter tools mainly because the field had a history of interdisciplinary work. Psychologists, computer scientists, and engineers worked together to under stand what support tools will improve the design process. While this influ ence continues today, there is an increased awareness that a much broader community needs to be involved."

Multibody systems are the appropriate models for predicting and evaluating performance of a variety of dynamical systems such as spacecraft, vehicles, mechanisms, robots or biomechanical systems. This book adresses the general problem of analysing the behaviour of such multibody systems by digital simulation. This implies that pre-computer analytical methods for deriving the system equations must be replaced by systematic computer oriented formalisms, which can be translated conveniently into efficient computer codes for - "generatin"g the system equations based on simple user data describing the system model - "solving" those complex equations yielding results ready for design evaluation. Emphasis is on computer based derivation of the system equations thus freeing the user from the time consuming and error-prone task of developing equations of motion for various problems again and again.

The application of computational electromagnetics to practical EMI/EMC engineering is an emerging technology. Because of the increased complexity in EMI/EMC issues resulting from advancements in electronics and telecommunications, it is no longer possible to rely exclusively on traditional techniques and tools to solve the growing list of electronic engineering design problems. EMI/EMC Computational Modeling Handbook introduces modeling and simulation of electromagnetics to real-world EMI/EMC engineering. It combines the essentials of electromagnetics, computational techniques, and actual EMI/EMC applications. Included are such popular full-wave computational modeling techniques as the Method of Moments, Finite-Difference Time Domain Technique, Finite Element Method, and several others. The authors have included a myriad of applications for computers, telecommunications, consumer electronics, medical electronics, and military uses. EMI/EMC Computational Modeling Handbook is an invaluable reference work for practicing EMI/EMC engineers, electronic design engineers, and any engineer involved in computational electromagnetics.

This book introduces robust estimation and failure detection, with a thorough presentation of Kalman filtering and H-infinity filtering theory. These estimation techniques make it possible for engineers to design estimators that are more general and robust. The book also reviews the likelihood ratio method for failure detection and demonstrates how to design failure detectors that are sensitive to failures but insensitive to model variations. This book will give engineers a concise presentation of these important techniques, as well as an overview of important robust control developments of the last fifteen years.

Multibody systems are used extensively in the investigation of mechanical systems including structural and non-structural applications. It can be argued that among all the areas in solid mechanics the methodologies and applications associated to multibody dynamics are those that provide an ideal framework to aggregate d- ferent disciplines. This idea is clearly reflected, e. g. , in the multidisciplinary applications in biomechanics that use multibody dynamics to describe the motion of the biological entities, in finite elements where multibody dynamics provides - werful tools to describe large motion and kinematic restrictions between system components, in system control where the methodologies used in multibody dynamics are the prime form of describing the systems under analysis, or even in many - plications that involve fluid-structure interaction or aero elasticity. The development of industrial products or the development of analysis tools, using multibody dynamics methodologies, requires that the final result of the devel- ments are the best possible within some limitations, i. e. , they must be optimal. Furthermore, the performance of the developed systems must either be relatively insensitive to some of their design parameters or be sensitive in a controlled manner to other variables. Therefore, the sensitivity analysis of such systems is fundamental to support the decision making process. This book presents a broad range of tools for designing mechanical systems ranging from the kinematic and dynamic analysis of rigid and flexible multibody systems to their advanced optimization.

Many important industrial applications incline toward better understanding of the constitutive properties of matter. Nowadays, the development of measurement possibilities, even in nanoscale, allows for multiscale formulations that drive to the more sophisticated models used in continuum mechanics. These phenomenological models are particularly important and useful for solutions of very concrete initial boundary value problems. Our interests are focused mainly on detailed descriptions of material behavior that depend not only on simple stress-strain relationships but also includes the strong influence of loading type, which introduces temperature, strain rate dependence, fracture, etc. Understanding these physics phenomena is of fundamental importance for successful and responsible computations. In particular, using the popular commercial programs requires deep understanding of constitutive formulations and their restrictions. These lectures are addressed to industrial users who are responsible for making crucial decisions in design, as well as, to young scientists who work on new models that describe the behavior of materials which also account the new influences and reflect the complexity of the material behavior. At the end, let me express my gratitude to the lecturers of the CISM course No. 328 on "Advances in Constitutive Relations Applied in Computer Codes", held in Udine in July 2007, who finally prepared the included materials. Unfortunately, during the preparation and collecting papers for this book, our friend and colleague Prof. Janusz R. Klepaczko passed away. This is a very big loss for the society of mechanics.

This book presents a useful way to "design in" electromagnetic compatibility (EM C). EMC design considerations are often an addendum to the design. These Band-Aid fixes are not the best approach most of the time but are all that is possible at a late stage in the design and development process. This book is not the classic "EMI fix cookbook"; it is intended for all electronics design engineers. The analytical tools presented enable the designer to address EMC considerations early in the design process. Power conversion engineers will find the enclosed information especially important because of the inherent conducted emissions problems in power conversion equipment. Switching power supplies are commonly the most significant noise generators in electronic systems. In most design work, if the conducted emission problem is addressed, good layout and packaging will ensure that the conducted and radiated electromagnetic interference (EM ) requirements are met. The EMI process involves three components: source, path, and victim. These elements are easily modeled on the computer. The methods of modeling and analysis on the computer are the essence of this book. The EMI source is analyzed using the FFr and the results are applied to a computer model of the path and victim (test setup). The resulting currents are measured and compared to a standard.

The impact of design 5 development performance on the overall business positions this area as an 6 important performance improvement opportunity. However, design devel- 7 opment is characterised by novelty, uniqueness and non-repeatability, which 8 provides particular challenges in de?ning, measuring and managing its 9 performance to achieve improvement. 2011 This book explores the support provided by both general research in busi- 1 ness process performance and design research for supporting performance 2 improvement in design development. The nature of design development in industrial practice is further revealed, and requirements for its modelling and 3 analysis to achieve improvement are highlighted. 4 A methodology for the modelling and analysis of performance in design 5 development that encapsulates a formalism of performance and an approach 6 for its analysis is established. The formalism is composed of three models, 7 which capture the nature of design development performance and support its 8 2 measurement and management. The E model formalises and relates the key 9 3011 elements of performance, i. e. , ef?ciency and effectiveness. The Design Activity 1 Management (DAM) model distinguishes design and design management 2 activities in terms of the knowledge processed, while the Performance 3 Measurement and Management (PMM) model describes how these activities 4 relate within a process of measuring and managing performance.

Interest in the fascinating field of multicriteria optimization and its application to design processes has grown very quickly in recent years. Researchers and practising engineers will find this book an comprehensive presentation of this subject. After an introduction to multicriteria optimization and the advantages of using multicriteria techniques, the first part of the book presents methods and computer procedures for solving multicriteria optimum design problems including interactive methods and knowledge-based systems. The second part presents an extensive range of applications of these methods to design processes in the fol- lowing fields: mechanisms and dynamic systems, aircraft and space technology, machine tool design, metal forming and cast metal technology, civil and architectural engineering, and structures made of advanced materials.

The Handbook of Electronics Packaging Design and Engineering has been writ ten as a reference source for use in the packaging design of electronics equip ment. It is designed to provide a single convenient source for the solution of re curring design problems. The primary consideration of any design is that the end product meet or exceed the applicable product specifications. The judicious use of uniform design practices will realize the following economies and equipment improvements: * Economics of design. Uniform design practices will result in less engineering and design times and lower costs. They will also reduce the number of changes that may be required due to poor reliability, maintainability, or producibility. * Improved design. Better designs with increased reliability, maintainability, and producibility will result from the use of uniform design practices. * Production economies. Uniform designs employing standard available tools, materials, and parts will result in the cost control of manufacturing. The Handbook is intended primarily for the serious student of electronics packaging and for those engineers and designers actively engaged in this vital and interesting profession. It attempts to present electronics packaging as it is today. It can be used as a training text for instructional purposes and as a reference source for the practicing designer and engineer.

M. Silva Significant changes have been occurring in industrialized countries since the Second World War. Production is moving towards sophisticated high qUality products, economy of scale has been replaced by economy of scope, jerky demands are progressively replacing steady demands, and competi tiveness is becoming a worldwide phenomenon. These trends require highly automated manufacturing systems with small set-up times and high flex ibility. As a consequence, implementation and running costs of modem manufacturing systems are drastically increasing, whereas their fields of application remain limited, and every day become even narrower, which increases the risk of early obsolescence. This is the reason why designers are trying to improve the preliminary design phase, also known as the 'paper study phase'. The preliminary design phase includes, but is not limited to, the func tional specification, and the evaluation of the system. Many tools exist to support the functional specification of manufactur ing systems. IDEFO is one of these tools. It leads, using a top-down ap proach, to a precise functional description of the required system. However, its use cannot be extended further. In general, the evaluation starts with a modeling step, which depends on the evaluation tool used, and ends by applying the model to find out its main dynamic characteristics. Two main approaches can be used to perform this task, namely simulation and math ematical approach. Using simulation, the modeling tool is either a classical computer language, or a simulation language."
