Upspeeding technological evolution and globalisation characterise today's and future lives of engineers. It is vital for all institutions involved in engineering education to keep pace and to anticipate future needs. The herein presented collection of papers results from the Workshop on Global Engineering Education (GEE'3) which took place at Aachen University of Technology, 18 - 20 October 2000. In this meeting more than 150 specialists from 25 countries discussed the topic "Educating the Engineer for the Century." Which role to attribute to non-technical qualifications? How to integrate ethical aspects in education? Do we have to define international standards in education? What about quality control? What is the potential of new media for knowledge transfer? How to organise lifelong learning for engineers? - These are some of the questions discussed among representatives of industries, educational institutions, politicians and individuals during this meeting. According to the sessions of the workshop, the book is subdivided into chapters covering the areas "Role of the Global Engineer in Meeting the Challenges of Society in the Century," "Internationality and Interdisciplinarity," "Engineering Education in Emerging Economies," "European Bachelor and Master Programmes," "Developing Personal Skills to be a Global Engineer." Three chapters deal with successful practice in engineering education covering the topics "Programmes, Curricula and Evaluation," "Educational Concepts," and "University-Industry Partnership, Design Projects."

"Modeling, Control and Coordination of Helicopter Systems" provides a comprehensive treatment of helicopter systems, ranging from related nonlinear flight dynamic modeling and stability analysis to advanced control design for single helicopter systems, and also covers issues related to the coordination and formation control of multiple helicopter systems to achieve high performance tasks. Ensuring stability in helicopter flight is a challenging problem for nonlinear control design and development. This book is a valuable reference on modeling, control and coordination of helicopter systems, providing readers with practical solutions for the problems that still plague helicopter system design and implementation. Readers will gain a complete picture of helicopters at the systems level, as well as a better understanding of the technical intricacies involved.

The essential aim of the present book is to consider a wide set of problems arising in the mathematical modelling of mechanical systems under unilateral constraints. In these investigations elastic and non-elastic deformations, friction and adhesion phenomena are taken into account. All the necessary mathematical tools are given: local boundary value problem formulations, construction of variational equations and inequalities, and the transition to minimization problems, existence and uniqueness theorems, and variational transformations (Friedrichs and Young-Fenchel-Moreau) to dual and saddle-point search problems. Important new results concern contact problems with friction. The Coulomb friction law and some others are considered, in which relative sliding velocities appear.

Stability and Controls Analysis for Delay Systems is devoted to stability, controllability and iterative learning control (ILC) to delay systems, including first order system, oscillating systems, impulsive systems, fractional systems, difference systems and stochastic systems raised from physics, biology, population dynamics, ecology and economics, currently not presented in other books on conventional fields. Delayed exponential matrix function approach is widely used to derive the representation and stability of the solutions and the controllability. ILC design are also established, which can be regarded as a way to find the control function. The broad variety of achieved results with rigorous proofs and many numerical examples make this book unique.

Manufacturing is the basic industrial activity generating real value. Cutting and abrasive technologies are the backbone of precision production in machine, automotive and aircraft building as well as of production of consumer goods. We present the knowledge of modern manufacturing in these technologies on the basis of scientific research. The theory of cutting and abrasive processes and the knowledge about their application in industrial practice are a prerequisite for the studies of manufacturing science and an important part of the curriculum of the master study in German mechanical engineering. The basis of this book is our lecture "Basics of cutting and abrasive processes" (4 semester hours/3 credit hours) at the Leibniz University Hannover, which we offer to the diploma and master students specializing in manufacturing science.

This is the third in a series of compendiums devoted to the subject of weld hot cracking. It contains 22 papers presented at the 3rd International Hot Cracking Workshop in Columbus, Ohio USA in March 2010. In the context of this workshop, the term "hot cracking" refers to elevated temperature cracking associated with either the weld metal or heat-affected zone. These hot cracking phenomena include weld solidification cracking, HAZ and weld metal liquation cracking, and ductility-dip cracking. The book is divided into three major sections based on material type; specifically aluminum alloys, steels, and nickel-base alloys. Each of these sections begins with a keynote paper from prominent researchers in the field: Dr. Sindo Kou from the University of Wisconsin, Dr. Thomas Bollinghaus from BAM and the University of Magdeburg, and Dr. John DuPont from Lehigh University. The papers contained within include the latest insight into the mechanisms associated with hot cracking in these materials and methods to prevent cracking through material selection, process modification, or other means. The three "Hot Cracking Phenomena in Welds" compendiums combined contain a total of 64 papers and represent the best collection of papers on the topic of hot cracking ever assembled.

Extensively revised and thoroughly updated, this popular text de-emphasizes high level mathematics in favor of effective, accurate modeling. Real-world examples amplify the theory and show how to use derived equations to model physical problems. Exercises that parallel the examples build readers' confidence and prepare them to confront the more complex situations they encounter as professionals.

Direct injection spark-ignition engines are becoming increasingly important, and their potential is still to be fully exploited. Increased power and torque coupled with further reductions in fuel consumption and emissions will be the clear trend for future developments. From today's perspective, the key technologies driving this development will be new fuel injection and combustion processes. The book presents the latest developments, illustrates and evaluates engine concepts such as downsizing and describes the requirements that have to be met by materials and operating fluids. The outlook at the end of the book discusses whether future spark-ignition engines will achieve the same level as diesel engines.

The objective of the 28th Leeds-Lyon Symposium on Tribology was to define current understanding of the science relating to boundary and mixed lubrication and to compare this with the needs of industry in terms of applications.

Major advances have been made in recent years in areas such as contact mechanics, wear, elastohydrodynamic lubrication incorporating surface texture, lubricant interactions with surfaces and the experimental interrogation of surface topography, surface films and lubricant film thickness. However, the needs of industry are equally intense with a seemingly relentless drive towards more compact, efficient and durable tribological systems.

"Boundary and Mixed Lubrication: Science and Applications" publishes peer-reviewed papers presented at the 28th Leeds-Lyon Symposium on Tribology. The Keynote address was presented by Professor Koji Kato, Tohoku University, Sendai, Japan under the title "Wear of Boundary or Mixed Lubrication Regimes," which set the scene for the meeting with a review of recent scientific developments with a clear focus on the potential for technological and industrial development.

This is the second book edited with a selection of papers from the two-yearly THIESEL Conference on Thermo- and Fluid Dynamic Processes in Diesel Engines, organised by CMT-Mvtores Termicos of the Universidad Po/itecnica de Valencia, Spain. This volume includes versions of papers selected from those presented at the THIESEL 2002 Conference th held on lOth to 13 September 2002. We hope it will be the second volume of a long series reflecting the quality of the THIESEL Conference. This year, the papers are grouped in six main thematic areas: State of the Art and Prospective, Injection Systems and Spray Formation, Combustion and Emissions, Engine Modelling, Alternative Combustion Concepts and Experimental Techniques. The actual conference covered a wider scope of topics, including Air Management and Fuels for Diesel Engines and a couple of papers included reflect this variety. However, the selection of papers published here represents the most current preoccupations of Diesel engine designers, namely how to improve the combustion process using new injection strategies and alternative concepts such as the Homogeneous Charge Combustion Ignition.

The significant advances witnessed over the last years in the broad field of linguistic variation testify to a growing convergence between sociolinguistic approaches and the somewhat older historical and comparative research traditions. Particularly within cognitive and functional linguistics, the evolution towards a maximally dynamic approach to language goes hand in hand with a renewed interest in corpus research and quantitative methods of analysis. Many researchers feel that only in this way one can do justice to the complex interaction of forces and factors involved in linguistic variability, both synchronically and diachronically. The contributions to the present volume illustrate the ongoing evolution of the field. By bringing together a series of analyses that rely on extensive corpuses to shed light on sociolinguistic, historical, and comparative forms of variation, the volume highlights the interaction between these subfields. Most of the contributions go back to talks presented at the meeting of the Societas Linguistica Europaea held in Leuven in 2001. The volume starts with a global typological view on the sociolinguistic landscape of Europe offered by Peter Auer. It is followed by a methodological proposal for measuring phonetic similarity between dialects designed by Paul Heggarty, April McMahon, and Robert McMahon. Various papers deal with specific phenomena of socially and conceptually driven variation within a single language. For Dutch, Jose Tummers, Dirk Speelman, and Dirk Geeraerts analyze inflectional variation in Belgian and Netherlandic Dutch, Reinhild Vandekerckhove focuses on interdialectal convergence between West-Flemish urban dialects, and Arjan van Leuvensteijn studies competing forms of address in the 17th century Dutch standard variety. The cultural and conceptual dimension is also present in the diachronic lexicosemantic explorations presented by Heli Tissari, Clara Molina, and Caroline Gevaert for English expressions referring to the experiential domains of love, sorrow and anger, respectively: the history of words is systematically linked up with the images they convey and the evolving conceptualizations they reveal. The papers by Heide Wegener and by Marcin Kilarski and Grzegorz Krynicki constitute a plea against arbitrariness of alternations at the level of nominal morphology: dealing with marked plural forms in German, and with gender assignment to English loanwords in the Scandinavian languages, respectively, their distributional accounts bring into the picture a variety of motivating factors. The four cross-linguistic studies that close the volume focus on the differing ways in which even closely related languages exploit parallel morphosyntactic patterns. They share the same methodological concern for combining rigorous parametrization and quantification with conceptual and discourse-functional explanations. While Griet Beheydt and Katleen Van den Steen confront the use of formally defined competing constructions in two Germanic and two Romance languages, respectively, Torsten Leuschner as well as Gisela Harras and Kirsten Proost analyze how a particular speaker's attitude is expressed differently in various Germanic languages.

The articles in this book present advanced soft methods related to genetic and evolutionary algorithms, immune systems, formulation of deterministic neural networks and Bayesian NN. Many attention is paid to hybrid systems for inverse analysis fusing soft methods and the finite element method. Numerical efficiency of these soft methods is illustrated on the analysis and design of complex engineering structures.

The Fifth International Symposium on Distributed Autonomous Robotic Systems (DARS 2000) dealt with new strategies to realize complex, modular, robust, and fault-tolerant robotic systems. Technologies, algorithms, and system architectures for distributed autonomous robotic systems were presented and discussed during the meeting. DARS 2000 was truly an international event, with participants represent ing eleven countries from Europe, Asia, and the Americas. All of the papers in this volume were presented at DARS 2000, and were selected on the basis of peer re views to ensure quality and relevance. These papers have the common goal of con tributing solutions to realize robust and intelligent multirobot systems. The topics of the symposium address a wide range of issues that are important in the development of decentralized robotic systems. These topics include architec tures, communication, biological inspirations, reconfigurable robots, localization, exploration and mapping, distributed sensing, multi robot motion coordination, tar get assignment and tracking, multirobot learning, and cooperative object transport. DARS clearly requires a broad area of interdisciplinary technologies related not only to robotics and computer engineering, but also to biology and psychology. The DARS symposium is the leading established conference on distributed au tonomous systems. The First, Second, and Third International Symposia on Distrib uted Autonomous Robotic Systems (DARS '92, DARS '94, and DARS '96) were held at the Institute of Physical and Chemical Research (RIKEN), Saitama, Japan."

Compliant mechanisms and actuators are growing in importance due to their benefits in robotics, medical technology, sensor applications, or in handling compressible objects. This book helps to understand the mechanical behavior of compliant systems. Suggested classifications and different modeling methods are shown that allow for the description of compliant systems.

This book discusses the development, types and application principles of portable air purifiers in China. It analyzes the theoretical characteristics of air purifiers under various operational conditions, and points out that the term "Clean Air Delivery Rate" cannot be used to precisely reflect the problems that occur under various operational conditions. By comparing theoretical and measured data, it highlights the mainfeatures of air purifiers and key points in the design process for different applications. Calculation methods for the indoor particle concentration and the self-purification time are also provided. The book describes the conditions for window opening in smog and for selecting air purifiers, and proposes a newmethod for improvingtheir measurement. In closing, it includes a new assessment index.

A systematic treatment of the thermal and elastic deformation of bearings, seals, and other machine elements under a wide variety of conditions, with particular emphasis on failure mechanisms when high speeds or loads cause significant frictional heating and on methods for predicting and avoiding such failures. Intended for designers and mechanical engineers responsible for high-performance machinery, the book is unique in discussing instabilities driven by frictional heating and thermal expansion and in developing a theoretical approach to engineering design in those cases in which the thermal problems are pivotal. It thus provides a guide as to what is important in the development of high-performance engineering systems. References to recent publications, new material that fill gaps in the literature, a consistent nomenclature, and a large number of worked examples make this a useful text and reference for both researchers and practising engineers.

It is our pleasure to present these proceedings for "The Aerodynamics of Heavy Vehicles II: Trucks, Buses and Trains" International Conference held in Lake - hoe, California, August 26-31, 2007 by Engineering Conferences International (ECI). Brought together were the world's leading scientists and engineers from industry, universities, and research laboratories, including truck and high-speed train manufacturers and operators. All were gathered to discuss computer simu- tion and experimental techniques to be applied for the design of the more efficient trucks, buses and high-speed trains required in future years. This was the second conference in the series. The focus of the first conference in 2002 was the interplay between computations and experiment in minimizing ae- dynamic drag. The present proceedings, from the 2007 conference, address the development and application of advanced aerodynamic simulation and experim- tal methods for state-of-the-art analysis and design, as well as the development of new ideas and trends holding promise for the coming 10-year time span. Also - cluded, are studies of heavy vehicle aerodynamic tractor and trailer add-on - vices, studies of schemes to delay undesirable flow separation, and studies of - derhood thermal management.

One of the next challenges in vehicular technology field is to improve drastically the road safety. Current developments are focusing on both vehicle platform and diverse assistance systems. This book presents a new engineering approach based on lean vehicle architecture ready for the drive-by-wire technology.

Based on a cognitive functionality split, execution and command levels are detailed. The execution level centralized over the stability control performs the motion vector coming from the command level. At this level the driver generates a motion vector which is continuously monitored by a virtual co-pilot. The integration of assistance systems in a safety relevant multi-agent system is presented here to provide first an adequate feedback to the driver to let him recover a dangerous situation. Robust strategies are also presented for the intervention phase once the command vehicle has to be optimized to stay within the safety envelope.

The unique focus of the book is the close symbiotic relationship between design and manufacture. It covers a large number of actual issues in the field by authors from the main research groups involved in developing methods, models and tools for the improvement of design and manufacturing processes in companies. It presents a selection of thirty-three papers ensuing from the fifth International Conference on Integrated Design and Manufacturing in Mechanical Engineering, held at the University of Bath, UK, in April 2004.

The contributions are divided in the following sections: two keynotes presenting the general synergies and relationships between the design and manufacturing processes through the concepts of production knowledge and integration; design strategies and methodologies, dealing with the critical element of knowledge in design and manufacturing processes and the methods with which designing can be undertaken collaboratively in an integrated manner; integrated design of manufacturing processes, which aim is to ensure a high quality product meeting all requirements, rapidly and at optimum cost; and design tools for particular applications in which texts optimising local decision have been grouped.

The book is of interest to academics, students and practitioners specialising in design and manufacturing issues in mechanical engineering, who will find it of the greatest interest to compare various points of view within the fields broached throughout the Conference. This volume is recommended as a reference textbook for all researchers in this field. It will give teachning staff confronted with training methodologies in integrated design and production a toolto assess the scope of the development prospects in an extremely wide ranging field.

Ready access to computers has de?ned a new era in teaching and learning. The opportunity to extend the subject matter of traditional science and engineering curricula into the realm of scienti?c computing has become not only desirable, but also necessary. Thanks to portability and low overhead and operating cost, experimentation by numerical simulation has become a viable substitute, and occasionally the only alternative, to physical experimentation. The new framework has necessitated the writing of texts and monographs from a modern perspective that incorporates numerical and computer progr- ming aspects as an integral part of the discourse. Under this modern directive, methods, concepts, and ideas are presented in a uni?ed fashion that motivates and underlines the urgency of the new elements, but neither compromises nor oversimpli?es the rigor of the classical approach. Interfacing fundamental concepts and practical methods of scienti?c c- puting can be implemented on di?erent levels. In one approach, theory and implementation are kept complementary and presented in a sequential fashion. In another approach, the coupling involves deriving computational methods and simulation algorithms, and translating equations into computer code - structions immediately following problem formulations. Seamlessly interjecting methods of scienti?c computing in the traditional discourse o?ers a powerful venue for developing analytical skills and obtaining physical insight.

There is a growing number of applications that require fast-rotating machines; motivation for this thesis comes from a project in which downsized spindles for micro-machining have been researched. The thesis focuses on analysis and design of high-speed PM machines and uses a practical design of a high-speed spindle drive as a test case. Phenomena, both mechanical and electromagnetic, that take precedence in high-speed permanent magnet machines are identified and systematized. The thesis identifies inherent speed limits of permanent magnet machines and correlates those limits with the basic parameters of the machines. The analytical expression of the limiting quantities does not only impose solid constraints on the machine design, but also creates the way for design optimization leading to the maximum mechanical and/or electromagnetic utilization of the machine. The models and electric-drive concepts developed in the thesis are evaluated in a practical setup.
