The Cambridge Workshops on Universal Access and Assistive Technology (CWUAAT) are a series of workshops held at a Cambridge University College every two years. The workshop theme: "Designing inclusion for real-world applications" refers to the emerging potential and relevance of the latest generations of inclusive design thinking, tools, techniques, and data, to mainstream project applications such as healthcare and the design of working environments. Inclusive Design Research involves developing tools and guidance enabling product designers to design for the widest possible population, for a given range of capabilities. There are five main themes: Designing for the Real-World Measuring Demand And Capabilities Designing Cognitive Interaction with Emerging Technologies Design for Inclusion Designing Inclusive Architecture In the tradition of CWUAAT, we have solicited and accepted
contributions over a wide range of topics, both within individual
themes and also across the workshop's scope. We ultimately hope to
generate more inter-disciplinary dialogues based on focused usage
cases that can provide the discipline necessary to drive further
novel research, leading to better designs. The aim is to impact
industry and end-users as well governance and public design,
thereby effectively reducing exclusion and difficulty in peoples'
daily lives and society.

In the past decades asset intensive companies have witnessed a number of regulatory changes and especially industry is facing ever increasing competitiveness. To overcome these challenges different asset management methods have been developed aimed to improve the asset life cycle. Especially the design phase and operation and maintenance phase have seen a rise in tools and methods. Smarter design can lead to improved operation. Likewise, improved operation and maintenance leads to lower replacement costs and may provide the basis for better design. This book brings together and coherently presents the current state of the art in asset management research and practice in Europe from a life cycle perspective. Each chapter focuses on specific parts of this life cycle and explains how the methods and techniques described are connected and how they improve the asset life cycle, thus treating this important subject from a unique perspective.
Environmental Design is becoming an increasingly significant agenda for many manufacturing companies and yet there is no standard to their approaches, strategies or their levels of execution. Applying Design for Environment (DfE) methodologies to develop a more sustainable supply chain has formed procedures and techniques which allow designers to integrate these methods with environmental supply chain management. Design for Environment as a Tool for the Development of a Sustainable Supply Chain aims to define relevant target specifications for a product throughout its life cycle; from conception and design to the end of its operating life. Be considering this new approach to the supply chain, environmental responsiveness can work in tandem with sounds business management. The usual focus on suppliers, manufacturers and customers is expanded in Design for Environment as a Tool for the Development of a Sustainable Supply Chain to include stakeholders such as government bodies and recycling companies. The influence of these additional groups is analyzed alongside concepts such as: Product life cycle development aimed at environmental impact minimization; Supplier selection and management based on environmental criteria; and Marketing and communication choices which increase the value of environmentally sensitive products. By including several case studies alongside theoretical topics, Design for Environment as a Tool for the Development of a Sustainable Supply Chains acts as a foundation for professionals across the supply chain, from industrial designers to marketing and sales departments, who are involved in environmental issues.

Incorporating recent developments of data mining that have made it possible to deal with management and engineering design problems with greater efficiency and efficacy, Data Mining presents a number of state-of-the-art topics. It will be an informative source of information for researchers, but will also be a useful reference work for industrial and managerial practitioners.
Undesign brings together leading artists, designers and theorists working at the intersection of art and design. The text focuses on design practices, and conceptual approaches, which challenge the traditional notion that design should emphasise its utility over aesthetic or other non-functional considerations. This publication brings to light emerging practices that consider the social, political and aesthetic potential of "undesigning" our complex designed world. In documenting these new developments, the book highlights the overlaps with science, engineering, biotechnology and hacktivism, which operate at the intersection of art and design.
This book describes new thinking and practice in Advanced Design (ADD) - design that is not merely highly developed but anticipates the future by envisioning novel products and processes. The focus is especially on the front end of innovation and the search for solutions in complex pioneering processes using design-related tools and practices. The book opens by describing these tools, the approaches that characterize ADD and its historical dimension. Specific fields in which ADD has flourished are then examined, exploring the dynamics between research and design. The coverage ranges from transportation, lighting and electrical appliances through to business networks, technology parks and the development of ground-breaking materials. Advance Design is the name of the research group at the Politecnico di Milano (Italy's largest technical university) of which the authors are members. It was chosen to reflect both the "advanced", tangible dimension of design in terms of modern product development, materials and technologies and an orientation toward radical innovation through user involvement and imagination.
Systems engineering is a mandatory approach in some industries, and is gaining wider acceptance for complex projects in general. However, under the imperative of delivering these projects on time and within budget, the focus has been mainly on the management aspects, with less attention to improving the core engineering activity - design. This book addresses the application of the system concept to design in several ways: by developing a deeper understanding of the system concept, by defining design and its characteristics within the process of engineering, and by applying the system concept to the early stage of design, where it has the greatest impact. A central theme of the book is that the purpose of engineering is to be useful in meeting the needs of society, and that therefore the ultimate measure of the benefit of applying the system concept should be the extent to which it advances the achievement of that purpose. Consequently, any consistent, top-down development of the functionality required of a solution to the problem of meeting a defined need must proceed from such a measure, and it is agued that a generalised form of Return on Investment is an appropriate measure. A theoretical framework for the development of functionality based on this measure and utilising the system concept is presented, together with some examples and practical guidelines.

Plate structures are used in almost every area of engineering, including aerospace and naval architecture, civil engineering, and electronics. These structures have diverse geometries and have to withstand a wide range of loading conditions. This book provides the theoretical foundations of the theories of plates manufactured from various materials, outlines and illustrates the methods used for the analysis of these structures, and emphasizes designs and solution techniques available to an engineer. The book is written for engineers working in industry, graduate students at aerospace, mechanical, civil engineering and naval architecture departments, and investigators interested in the development of the theory of plates and related subjects. While the mathematical modeling employed in the book is understandable to both engineers and graduate students, the book also provides insight into relevant phenomena and theories underlying plate structures. Thus, the reader is equipped with a thorough understanding of the problems and appropriate assumptions, even if the analysis is conducted using commercially available software codes. In addition, the book includes numerous analytical solutions that can confidently be used in the design of plate structures. The combination of theoretical insight and references to practical problems makes the book equally attractive to academia and industry.
"Design Rules for Actuators in Active Mechanical Systems" deals with the formulation of model-based design rules to be used in the conception of optimized mechatronic and adaptronic systems. The book addresses the comparison of different actuator classes for given applications and offers answers to the following questions: What is the relationship between actuator geometry and primary output quantities? How scalable are actuators based on the same principle? How are energetic output quantities (work and power) related to mechanical load and geometry? How should actuators be designed and sized to obtain the best performance for the chosen actuator kind, and for a given application? "Design Rules for Actuators in Active Mechanical Systems" will be of use to industry professionals, such as actuator and machine designers, as well as to researchers and students of mechanical engineering, mechatronics, and electrical engineering.
Design considerations for low-power operations and robustness with respect to variations typically impose contradictory requirements. Low-power design techniques such as voltage scaling, dual-threshold assignment and gate sizing can have large negative impact on parametric yield under process variations. This book focuses on circuit/architectural design techniques for achieving low power operation under parameter variations. We consider both logic and memory design aspects and cover modeling and analysis, as well as design methodology to achieve simultaneously low power and variation tolerance, while minimizing design overhead. This book will discuss current industrial practices and emerging challenges at future technology nodes.
As the main theme of Improving Complex Systems Today implies, this book is intended to provide readers with a new perspective on concurrent engineering from the standpoint of systems engineering. It can serve as a versatile tool to help readers to navigate the ever-changing state of this particular field. The primary focus of concurrent engineering was, at first, on bringing downstream information as far upstream as possible by introducing parallel processing in order to reduce time to market and to prevent errors at a later stage which would sometimes cause irrevocable damage. Up to now, numerous new concepts, methodologies and tools have been developed, but over concurrent engineering's 20-year history the situation has changed extensively. Now, industry has to work in the global marketplace and to cope with diversifying requirements and increasing complexities. Such globalization and diversification necessitate collaboration across different fields and across national boundaries. Thus, the new concurrent engineering calls for a systems approach to gain global market competitiveness. Improving Complex Systems Today provides a new insight into concurrent engineering today.
In an age of increasing complexity, diversification and change, customers expect services that cater to their needs and to their tastes. Emotional Engineering vol 2. describes how their expectations can be satisfied and managed throughout the product life cycle, if producers focus their attention more on emotion. Emotional engineering provides the means to integrate products to create a new social framework and develops services beyond product realization to create of value across a full lifetime. 14 chapters cover a wide range of topics that can be applied to product, process and industry development, with special attention paid to the increasing importance of sensing in the age of extensive and frequent changes, including: Multisensory stimulation and user experience Physiological measurement Tactile sensation Emotional quality management Mental model Kansei engineering. Emotional Engineering vol 2 builds on Dr Fukuda's previous book, Emotional Engineering, and provides readers with a holistic view of its research and applications, enabling them to make strategic decisions on how they can go further beyond product realization. It is recommended for all pioneers in industry, academia and government, who are making tremendous efforts to work with their customers to create value.
The possible use of adhesives in a new design should always be considered because of the economic and technical benefits thatthey can confer. Light, stiff and economic structures, free of the blemishes caused by conventional assembly methods, can be fabricated from a variety of materials in combinations which would otherwise be hard to achieve. Similarly, mechanisms may be built up using bonding techniques which are free of the costs and stresses implicit in press fitting. Adhesives are not a panacea, but they do have a great deal to offer as is shown by the vital role they play in modern production engineering. Yet, despite this, they are not generally regarded with enthusiasm by engineers and designers. The reason for this is not hard to find. There are so many adhesives with such diverse properties that, in the absence of a unifying science which can explain not only why adhesives stick but why they behave as they do, a very strong incentive is required to guarantee perseverance. In addition, although the polymeric structures of adhesives are well understood, this knowledge is usually of little help to the engineer who is used to dealing in precise terms and may be readily put off by a subject which he tends to regard as being arcane and wooly.
During the period 1982-1985, six books of the series: Scientific Fun damentals of Robotics were published by Springer-Verlag. In chronolo gical order these were: Dynamics of Manipulation Robots: Theory and Application, by M. Vukobra tovic and V. Potkonjak, Control of Manipulation Robots: Theory and Ap plication, by M. vukobratovic and D. Stokic, Kinematics and Trajectory Synthesis of Manipulation Robots, by M. Vukobratovic and H. Kircanski, Real-Time Dynamics of Hanipulation Robots by M. Vukobratovic and N. Kircanski, Non-Adaptive and Adaptive Control of Manipulation Robots, by M. Vukobratovic, D. Stokic and N. Kircanski and Computer-Aided De sign and Applied Dynamics of Manipulation Robots, by M. Vukobratovic and V. Potkonjak. Within the series, during 1989, two monographs dealing with new sub jects will be published. So far, amongst the published monographs, Vol. 1 has been translated into Japanese, Volumes 2 and 5 into Russian, and Volumes 1-6 will appear in Chinese and Hungarian. In the author's opinion, the afore mentioned monographs, in principle, cover with sufficient breadth, the topics devoted to the design of ro bots and their control systems, at the level of post-graduate study in robotics. However, if this material was also to apply to the study of robotics at under-graduate level, it would have to be modified so as to obtain the character of a textbook. With this in mind, it must be noted that the subject matter contained in the text cannot be simpli fied but can only be elaborated in more detail."
In the field of plastics technology, the process of extrusion is widespread and important. It is employed in the compounding and pelletising of plastics materials, in their conversion into products (such as profiles, pipe, hose, sheet, film or bottles) and in the coating of wires, cables, paper, board or foil. A major reason for its use is the screw extruder's ability to melt efficiently and pump continuously large amounts of plastics materials. The understanding of the melting/pumping operation of the extruder and the development of larger and faster-running machines so as to give higher outputs have been given great attention and the results have been widely published. However, the whole manufacturing technology for extruded products has also developed, particularly in recent years. This has occurred not only by the use of modern screw extruders, but also by the incorporation of improved process control systems, the better design of dies and extrudate handling machinery and by the utilisation of improved plastics materials and additives. It is the purpose of this book to present selected topics which contribute to, or exemplify, these developments in extrusion-based processes.
In recent years, interest in the technology of gas cleaning has grown, driven partly by environmental legislation, but also by demands for increases in process efficiency and intensity - notable for power generation and waste incineration. This book, which leads on from our successful Gas Cleaning at High Temperatures, describes the present state of the art and its industrial applications. |
