Shows why plastics, in aggregate, have become a toxin to humans, wildlife, and the planet, and proposes novel solutions that involve neither traditional recycling nor giving up plastic. "Plastics!" In the 50 years since Dustin Hoffman's character in The Graduate was instructed that this was the career field of the future, we have not been able to escape this ubiquitous but poorly understood material. Author Jack Buffington argues that the plastics crisis is careening toward a tipping point from which there will be no return. There is still time, however, to do something about this crisis if we have the imagination and the will to move away from the failed policies of the past. This book is the first to propose a new model for linking our synthetic world to the natural one, rather than seeking to treat them as separate entities. The key is supply chain innovation. Buffington presents five market-based solutions based on this principle that will allow consumers to continue to use plastic, which has in many ways enabled our way of life. Alongside these proposed solutions, he also addresses the proliferation of plastic as we know it-growth that, if left unchecked, will lead to a "planetary crisis," according to the United Nations-and considers how the material itself might be adapted for a sustainable future. Provides a realistic solution for our use of plastic: not to eliminate it, but to innovate it Views plastic not only as a known environmental and health hazard but as a material critical to our future and therefore worth revising for future use Explains what we must do-and by when-in order to be able to keep using plastic without harming the planet or our health Shows the links between the environmental, toxicological, and socioeconomic challenges in our use of plastic, and how these dangers can be remedied by supply chain innovation Introduces two significant disruptive innovations that if implemented, will save us from the growing problem posed by synthetics

The process of reverse engineering has proven infinitely useful for analyzing Original Equipment Manufacturer (OEM) components to duplicate or repair them, or simply improve on their design. A guidebook to the rapid-fire changes in this area, Reverse Engineering: Technology of Reinvention introduces the fundamental principles, advanced methodologies, and other essential aspects of reverse engineering. The book's primary objective is twofold: to advance the technology of reinvention through reverse engineering and to improve the competitiveness of commercial parts in the aftermarket. Assembling and synergizing material from several different fields, this book prepares readers with the skills, knowledge, and abilities required to successfully apply reverse engineering in diverse fields ranging from aerospace, automotive, and medical device industries to academic research, accident investigation, and legal and forensic analyses. With this mission of preparation in mind, the author offers real-world examples to: Enrich readers' understanding of reverse engineering processes, empowering them with alternative options regarding part production Explain the latest technologies, practices, specifications, and regulations in reverse engineering Enable readers to judge if a "duplicated or repaired" part will meet the design functionality of the OEM part This book sets itself apart by covering seven key subjects: geometric measurement, part evaluation, materials identification, manufacturing process verification, data analysis, system compatibility, and intelligent property protection. Helpful in making new, compatible products that are cheaper than others on the market, the author provides the tools to uncover or clarify features of commercial products that were either previously unknown, misunderstood, or not used in the most effective way.

This book reveals how a generative design process capitalizes on understanding humans in context to deliver appropriate innovation. A repertoire of design actions and output allows designers to work dynamically in order to create a cascade of new ideas and insights. The Design Matrix, a visual team tool, provides a prescriptive and descriptive guide enabling a range of users to work through a problem and also reflect on past decisions. Several case studies from prior industry collaborative projects show the complexities and tensions that can be tackled through the design process and matrix. Case studies include design and engineering development and production of an 8 Tesla MRI, biomedical projects, medical devices, and consumer products. Other cases with Ford Motor Company and Cognizant Technologies illustrate how using a human-centered design process can shift the business paradigm for new products, services, systems, and social innovations. Each story shows different and distinct aspects that span classic design and engineering problem solving to generative contextual processes which lead to innovative solutions. Describes a studio-based product development pedagogy so readers can understand through past examples how to operationalize their own design, engineering, and innovation processes; Provides specific stories that showcase details of the project work, the contextual insights, and proposed solutions as a result of applying tangible visualizations, collaborative work methods, and framing and reframing of the problem; Uses case studies to demonstrate how to use divergent and convergent design thinking and actions from multiple stages of the design process so this can lead to critical team integration and new contextual insights.

This open access textbook introduces the emerging field of Development Engineering and its constituent theories, methods, and applications. It is both a teaching text for students and a resource for researchers and practitioners engaged in the design and scaling of technologies for low-resource communities. The scope is broad, ranging from the development of mobile applications for low-literacy users to hardware and software solutions for providing electricity and water in remote settings. It is also highly interdisciplinary, drawing on methods and theory from the social sciences as well as engineering and the natural sciences. The opening section reviews the history of "technology-for-development" research, and presents a framework that formalizes this body of work and begins its transformation into an academic discipline. It identifies common challenges in development and explains the book's iterative approach of "innovation, implementation, evaluation, adaptation." Each of the next six thematic sections focuses on a different sector: energy and environment; market performance; education and labor; water, sanitation and health; digital governance; and connectivity. These thematic sections contain case studies from landmark research that directly integrates engineering innovation with technically rigorous methods from the social sciences. Each case study describes the design, evaluation, and/or scaling of a technology in the field and follows a single form, with common elements and discussion questions, to create continuity and pedagogical consistency. Together, they highlight successful solutions to development challenges, while also analyzing the rarely discussed failures. The book concludes by reiterating the core principles of development engineering illustrated in the case studies, highlighting common challenges that engineers and scientists will face in designing technology interventions that sustainably accelerate economic development. Development Engineering provides, for the first time, a coherent intellectual framework for attacking the challenges of poverty and global climate change through the design of better technologies. It offers the rigorous discipline needed to channel the energy of a new generation of scientists and engineers toward advancing social justice and improved living conditions in low-resource communities around the world.

In order to develop innovative products, to reduce development costs and the number of prototypes and to accelerate development processes, numerical simulations become more and more attractive. As such, numerical simulations are instrumental in understanding complicated material properties like chemical ageing, crack propagation or the strain- and temperature-induced crystallisation of rubber. Therefore, experimentally validated and physically meaningful constitutive models are indispensable. Elastomers are used for products like tyres, engine and suspension mounts or seals, to name a few. The interest in modelling the quasi-static stress-strain behaviour was dominant in the past decades, but nowadays the interests also include influences of environmental conditions. The latest developments on the material behaviour of elastomers are collected in the present volume. Constitutive Models for Rubber X is a comprehensive compilation of nearly all oral and poster contributions to the European Conference on Constitutive Models for Rubber (Munich, 28-31 August 2017). The 95 highly topical contributions reflect the state of-the-art in material modelling and testing of elastomers. They cover the fields of material testing and processing, filler reinforcement, electromagnetic sensitive elastomers, dynamic properties, constitutive modelling, micromechanics, finite element implementation, stress softening, chemical ageing, fatigue and durability. In the area of rubbery materials and structures, applied research will play an important role also in the coming decades. Constitutive Models for Rubber X is of interest to developers and researchers involved in the rubber processing and CAE software industries, as well as for academics in nearly all disciplines of engineering and material sciences.

Fundamental to the control of mechatronic devices, the servomechanism applies feedback from the device in question to regulate its position, velocity, or some other physical attribute. Successful mastery of servo control requires an understanding of a wide range of engineering disciplines, making it difficult and time-consuming to master it all-and even harder to find an all-encompassing guide that shows you how. DC Servos: Application and Design with MATLAB (R) is designed and written with this problem in mind. It breaks down the practical knowledge required from the various branches of applied science-electrical and mechanical engineering, analog electronics, mechanics, control theory, digital electronics, embedded computing, and firmware design-into a cohesive and usable framework. Today, DC servos are working around the world in countless applications-CD players, ink-jet printers, robots, machining centers, vending machines, eyeglass manufacturing machines, home appliances, and automotive seat positioners, just to name a few. This book balances coverage of theoretical and practical aspects of application and design of DC servomechanisms. It also provides detailed coverage of feedback transducers, particularly the application of optical encoders to real systems. It covers how to use the MATLAB (R) Control System Toolbox specifically for servo design, to make the design process faster and more interactive. It also presents two complete, bench-tested reference designs that can be duplicated using readily available parts, so you can build your own servo and see it in action. Author Stephen M. Tobin is an expert in motion control and electro-optical instrumentation and a respected consultant in the medical device and manufacturing automation communities. In order to instill confidence in the engineers, scientists, students, and hobbyists designing the ever more complex machines of the 21st century, Tobin guides the reader on a short journey through "servo school," imparting his lifelong passion for motion control along the way.

Die Konstruktion bestimmt den Entwurf eines Bauwerkes neben der Funktion, der Wirtschaftlichkeit und der formalen Gestaltung als gleich- berechtigte Komponente. Mitwirkende Faktoren sind daruber hinaus ortliche Verhaltnisse, rechtliche Bindungen, einschrankende Vorschriften, politische Absichten, Neigungen zu Tradition und Prestige usw. Architekt und Ingenieur haben diese Forderungen aufeinander abzustimmen und damit eine schwere und stets neue Aufgabe zu bewaltigen. Es ist oft zu beobachten, dass eine ausgewogene Synthese der vier Hauptkomponenten, die aus verstandnisvoller und sorgfaltiger Zusammenarbeit gleichwertiger Partner hervorgeht, sich sowohl in der Harmonie des Gesamtbauwerkes als auch der Einzelteile deutlich auspragt. Vorbedingung hierzu ist der rechtzeitige Kontakt zwischen Bau-Ingenieur und -Kunstler und deren Fahigkeit, die Arbeitsweise des anderen zu verstehen. Nur so lasst sich der Riss uberbrucken, der in der ersten Halfte des vorigen Jahrhunderts aus dem universellen "Baumeister" zwei spezialisierte Bauberufe wer- den liess. Diese Spaltung war der Preis fur das Werkzeug "Naturwissen- schaft", das erst die technische Entwicklung des Bauwesens bis zu seiner heutigen Hohe ermoglichte. Die harmonische Gestaltung von Bauwerken ist deshalb jetzt - bis auf wenige Ausnahmen - nur in enger Gemeinschaftsarbeit der Spezialisten moglich. Die modernen Bauweisen haben ihren Ursprung in der allgemeinen Entwicklung der Technik, die, durch die politischen Verhaltnisse begun- stigt, als "erste technische Revolution" bezeichnet worden ist. In jenen Jahrzehnten um die Mitte des vorigen Jahrhunderts forderten einerseits Industrie und Handel sowie Transport und Lagerung wachsender Waren- mengen und die Verkehrsbedurfnisse neue, leistungsfahigere Bauweisen, andererseits konnten Stahl und Zement erst im Zeitalter der Kraft- maschinen in grossen Mengen wirtschaftlich hergestellt werden.

Internet 2.0 (previously called the Internet of Things) presents a tantalizing vision of bridging the cyber and physical worlds to forge a seamless planet-wide infrastructure in which cyber resources and physical objects can interact without human intervention. The technology needed to build the infrastructure already exists. However, more than a decade after the vision of Internet 2.0 was articulated, it remains largely unrealized except in isolated settings. Following a background discussion, Design and Construction of an RFID-enabled Infrastructure: the Next Avatar of the Internet addresses three questions: what are the barriers to the emergence of Internet 2.0 as a global infrastructure? What are the features that Internet 2.0 architecture must have if it is to become a successful global infrastructure?How can one build a prototype of Internet 2.0? The quest for answers to the above questions threads the narrative through the birthing process and maturation of two successful global infrastructures-the Internet and the web. Based on a review of the design philosophies underlying the Internet and the Web, their histories and the strategic stewardship that midwifed their births, the book presents the architectural guidelines for the Internet 2.0 infrastructure as well as a blueprint for the construction of its prototype. The discussion in the book is consolidated into a list of technical and strategic guidelines intended to facilitate the incubation of Internet 2.0.

This book helps students and practitioners understand that there is a rigorous way to analyze engineering decisions taking into consideration all the potential technical and business impacts of their decisions. It can be used in its entirety to teach a course in decision based design, while selected chapters can also be used to cover courses in subdisciplines that make up decision based design.

TO THE GERMAN EDITION This book is addressed to those engineering students who are prepared to work-not to such as are content to refurbish existing designs without taking the trouble to understand the trains of thought and the considerations which are needed in true design work. It is a well-established fact that the beginner, confronted by the simplest of design problems, and lacking a pattern or model to suggest a solution, loses his way in endless trial and error unless given positive guidance. In this book, therefore, the author has drawn on his long teaching experience in an attempt to present in a readily understandable and systematic manner a methodical work plan which will enable the beginner practising design problems to reach his objective by a rational route. This approach has the further advantage. con firmed by experience, that in adopting it the student will find his interest and pleasure in design work growing, and his self-confidence increasing. Written with the requirements of general mechanical engineering in mind, the book does not deal with the manufacturing methods typical of light precision engineering. To prevent the book from taking on a size which would have detracted from its clear layout and obscured the main principles presented, the numerical tables, graphs, etc. available for reference in pocket books and textbooks have been omitted."

In geomechanics, existing design methods are very much dependent upon sophisticated on-site techniques to assess ground conditions. This book describes numerical analysis, computer simulation and modelling that can be used to answer some highly complex questions associated with geomechanics. The contributors, who are all international experts in the field, also give insights into the future directions of these methods. Numerical Analysis and Modelling in Geomechanics will appeal to professional engineers involved in designing and building both onshore and offshore structures, where geomechanical considerations may well be outside the usual codes of practice, and therefore specialist advice is required. Postgraduate researchers, degree students carrying out project work in this area will also find the book an invaluable resource.

Ethical Design Intelligence: The Virtuous Designer explores the deep significance of philosophy and ethics to the practice of design. It offers designers from disciplines such as architecture, urban design, planning, landscape, interior, and industrial design an alternative ethical framework in which to expand their thinking about their practice. Arguing that design today is primarily an agency driven by the momentum of globalization, embedded in economy, materialism, and utility, the book reconceptualizes the notion of virtue in design practice. Across chapters covering topics such as virtuous character, creative agency, and unsustainable practices, the book scrutinizes design through a philosophical lens. d'Anjou dissects articulations from different philosophical thinkers from antiquity to contemporary time to reveal that ethics is fundamental to everything affected by design. Countering well-established modes of postmodern relativism in design, which has led to "defuturing" and "unsustainability," ethical realism is presented as an alternative solution. This book is written for designers, educators, researchers, and students.
