This book covers the most important topics in the field of personalized orthopedics. It starts with the 3D geometry of the bones, focusing on the problem of reverse engineering of the bones. It also shows the application of a 3D geometric model of bone for the design of personalized implants and prostheses.

Congratulations and thank you for reading this book! You hold in your hand perhaps the first book solely written on mechanical reverse engineering from an industry perspective. The motivation for this book originates from the needs of today’s global industry. We recall an incident during one of our industrial trips to a local manufact- ing company. The office secretary was photocopying documents for this me- ing, when the manufacturing manager remarked, “Wouldn’t it be nice if I could do the same with mechanical parts, it would save me and my team a lot of time and money. ” “Have you not heard of reverse engineering?” we asked him. “- verse engineering, isn’t that something to do with programming computers?” “No,” we replied. “Reverse engineering (RE) refers to creating a computer-aided design (CAD) model from an existing physical object, which can be used as a design tool for producing a copy of an object, extracting the design concept of an existing model, or reengineering an existing part. ” His eyes lit up. Such sit- tions are not uncommon in today’s manufacturing arena. With globalization and trade liberalization, manufacturing companies face increasing competition from goods and services produced in lower wage eco- mies. Countries in the West cannot compete against low wages and must the- fore depend on raising innovation and best practices to create better products.

This book, building on research initiated by scholars from the Leiden-Delft-Erasmus Centre for Global Heritage and Development (CHGD) and ICOMOS Netherlands, presents multidisciplinary research that connects water to heritage. Through twenty-one chapters it explores landscapes, cities, engineering structures and buildings from around the world. It describes how people have actively shaped the course, form and function of water for human settlement and the development of civilizations, establishing socio-economic structures, policies and cultures; a rich world of narratives, laws and practices; and an extensive network of infrastructure, buildings and urban form.

This book provides readers with a timely snapshot of ergonomics research and methods applied to the design, development and evaluation, of products, systems and services. It gathers theoretical contributions, case studies and reports on technical interventions focusing on a better understanding of human machine interaction, and user experience for improving product design.

The German Academic Association for Production Technology (WGP) annually invites researchers coming from its institutes and from industry to contribute peer reviewed papers in the field of production technology. This congress proceedings provides recent research results and findings on leading-edge manufacturing processes. Main aim of this scientific congress is to push forward existing borders in production and to provide novel solutions of "Production at the Leading Edge of Manufacturing Technology.

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.

The idea to use air for transmitting power is very old. Ctesibius in - cient Greece described a catapult using pneumatic cylinders to first store energy and then rapidly accelerate an arrow. Heron of Alexandria dev- oped automatic temple doors which opened and closed by means of hot air. And from the Greek word for breath he coined the term that was used as title for his book and today describes a whole industry: - pneumatics. Pneumatic components and systems have become an important topic for textbooks. Most have their focus on the description of the steady-state - haviour, practical problems like troubleshooting or Boolean algebra to help designing control algorithms. Only a few textbooks covering the theore- cal analysis and design of pneumatic systems have been published (Z- manzon et al. 1965; Andersen 1967; Andersson et al. 1975). But they were written at a time when digital computers were not easily available to en- neers and therefore contain few material about modelling and simulation. This book tries to bridge the gap between scientific disciplines (fluid mechanics, thermodynamics, mathematics, control, etc.), the conventional approach to describe pneumatic components and systems by their stea- state behaviour, the wish of a design engineer to test his design before - tually building hardware and the resulting need for mathematical models in order to use today’s powerful digital computers.

Although Leonardo’s Giant Crossbow is one of his most popular drawings, it has been one of the least understood. "Leonardo’s Giant Crossbow" offers the first in-depth account of this drawing’s likely purpose and its highly resolved design. This fascinating book has a wealth of technical information about the Giant Crossbow drawing, as it’s a complete study of this project, though this is as accessible to the general audience as much as it is also informative with new discoveries for the professors of engineering, technology and art. The book explores the context of Leonardo’s invention with an examination of the extensive documentary evidence, a short history of the great crossbow and ballista, the first accurate translation of the text and the technical specifications, and a detailed analysis of Leonardo’s design process for the crossbow, from start to finish. Dozens of preparatory drawings, along with the recent discovery of nearly invisible metal stylus preparatory incisions under the ink of the Giant Crossbow drawing, are evidence of Leonardo’s intent to offer engineers and other viewers a thorough design of the massive machine. The book proposes these new discoveries with the help of a strategy that had been at the core of Leonardo’s working philosophy: the proportional method. As proven with an analysis of the Giant Crossbow project, he used a consistent approach to 1/3rd proportions throughout the design and drawing process and employed this kind of proportional strategy at the start of almost every important project. Thanks to this proof of his knowledge of geometry, evidence of his studies of impetus and force, and thanks to the highly polished and complex nature of the Giant Crossbow design, a later date for the drawing is proposed in the present book, associating the drawing with his drafting capabilities around 1490-93.

When a heating fluid transfers heat to a heated fluid through a wall, if the fluids are in parallel flow or counter flow it is possible to compute exactly both the transferred heat and the temperatures of the fluids via well-known equations. This holds true both for design and verification computation. However, the motion of the fluids is never in parallel flow or counter flow in heat exchangers and in tube banks. Instead, it is rather complex and consists of a combination of various cross flows. Hence, a precise design of the above components requires, on a case-by-case basis, the availability of the value of certain crucial factors or of corrective factors so as to make it possible to use the equations relative to parallel flow or counter flow. This handbook contains the introduction to the problem, its design criteria, and about 70 tables for the exact design and verification computation. It also indicates how to proceed in the case of cross flow.

This book is a generalist textbook; it is designed for anybody interested in heat transmission, including scholars, designers and students.

This book showcases cutting-edge research papers from the 9th International Conference on Research into Design (ICoRD 2023) – the largest in India in this area – written by eminent researchers from across the world on design processes, technologies, methods and tools, and their impact on innovation, for supporting design for a connected world. The theme of ICoRD’23 has been ‘Design in the Era of Industry 4.0’. Industry 4.0 signifies the fourth industrial revolution. The first industrial revolution was driven by the introduction of mechanical power such as steam and water engines to replace human and animal labour. The second industrial revolution involved introduction of electrical power and organised labour. The third industrial revolution was powered by introduction of industrial automation.

The content of this book originates from 35 years of teaching “steam generators” to graduate students at the Politecnico of Milan, Milan, Italy, and from 45 years of professional activity in this area – rst in industry and then as founder of a design and consulting company. Beforediscussingthecontentofthetextbook,Iwouldliketopresenttherationale for the title. Boilers are machines consisting of steam-generating tubes only, that is, of internal and external tubes where water is transformed into saturated steam. Steam generators – or, simply, generators – indicate machines equipped with one or more of the following components: superheaters, reheaters, economizers, and air heaters – besides the steam-generating tubes that make up the boiler. Finally, those machines with tubes, where instead of water, a diathermic uid ows inside, are also called boilers, for their construction is similar to that of the latter. The above notwithstanding, the term “boiler” is used even when hot water or superheated water is produced instead of steam. Large systems designed to produce electricity have all components indicated above in addition to the boiler. In medium size systems, some of these components are always present, whereas in small ones a regenerator is frequently and approp- ately included. It is therefore justi ed to use “steam generators” as title, because it best matches the actual makeup of these systems.

Pumps are one of the mechanical devices that are widely used in many industries throughout the world. Turbopumps which are common types of pumps are used mainly for transporting water in agricultural units, industrial processes, cooling and heating systems, and power plants. But their application is not limited only for h- dling water. Turbopumps can be used for transporting oil products in oil and gas industries and re neries, as well as byproductsin pulp and paper industry, food and beverage in food industry, and contaminated water in sewage systems. Because of the versatility of pump usage, the numberof turbopumpsin operation worldwide is very large and as a result the total energy consumption of these units can be considerable. To reduce the energy consumption by turbopumps, it is imp- tant to increase the ef ciency of the pumps, as well as the system they are working in. The pump manufacturing companies and design engineers are constantly trying to improve the performances of pumps by designing more ef cient pumps and by using the latest technologies available in terms of design software, new developed materials, and state of the art manufacturing tools. Today, computational uid - namics and sophisticated design software tools help designers to optimize the uid ow inside the pumps and to design different pump elements with better hydraulic ef ciencies. However, the operation of turbopumps can be optimized a well by effectively using proper pumps and designing ef cient piping systems.

A typical method of dealing with input and output constraints, especially for PID control, has been the empirical design and implementation of an intuitive solution to an individual plant and its constraints. Such ad hoc solutions perform surprisingly well but often remain in the form of isolated practical know-how without a more general scientific basis.

Relay feedback has attracted considerable research attention for more than a century but there has been no recent summary of the many newly-developed tools and results now available for this important area as a whole, those that have been published tending to focus on one process or controller type only. Relay Feedback is divided into three parts, the first of which is devoted to the analysis of relay feedback systems within a general setting with information on: existence of solutions; existence of limit cycles; local and global stability of limit cycles; limit cycles with more than two switchings per period; plants with time delay; relays with asymmetric hysteresis. The second part, on the improvement of process identification shows the reader how to: modify a standard relay to provide better excitation of a process at a number of important frequencies; devise new algorithms designed to make better use of information from relay feedback tests. The book's third part is a presentation of recent developments in control design providing: a unified framework for the design of internal-model, proportional-integral-derivative or general-single-loop controllers for SISO or MIMO systems with or without time delays; characterisation of time delays and non-minimum phase zeros for closed-loop systems. Relay Feedback presents 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. The work assumes only knowledge of linear system theory on the part of the reader and should therefore be of use to graduate students and practising engineers as well as to researchers.
