This dissertation provides a novel design approach with respect to ruled surface, which is a special type of surface generated by moving a line in the space. Ruled surface is a favorable choice in manufacture and can be found in many application fields. In this dissertation, a ruled surface in Euclidean space is represented as a curve on a dual unit sphere (DUS) by employing the Klein mapping and the Study mapping. A novel definition of dual spherical spline is proposed and a complete kinematic ruled surface approximation algorithm is developed and tested with turbocharger blade data. More generally, a ruled surface is defined by several control points of a dual spherical spline. It provides an initial prototype for the blade geometry optimization with ruled surface. Finally, combining the kinematic ruled surface approximation algorithm with the offset theory, a novel design and manu- facturing strategy is proposed. A desired surface is presented as a tool path of the flank milling method with a cylindrical tool in 5-axis CNC machining. It integrates the manufacturing requirements in the design phase, which can reduce the design- cycle time and save the manufacturing cost.

Extensive numerical methods for computing design sensitivity are included in the text for practical application and software development. The numerical method allows integration of CAD-FEA-DSA software tools, so that design optimization can be carried out using CAD geometric models instead of FEA models. This capability allows integration of CAD-CAE-CAM so that optimized designs can be manufactured effectively.

A topic of utmost importance in civil engineering is finding optimal solutions throughout the life cycle of buildings and infrastructural objects, including their design, manufacturing, use, and maintenance. Operational research, management science, and optimization methods provide a consistent and applicable groundwork for engineering decision-making. These topics have received the interest of researchers and, after a rigorous peer-review process, eight papers have been published in this Special Issue. The articles in this Printed Edition demonstrate how solutions in civil engineering, which bring economic, social, and environmental benefits, are obtained through a variety of methodologies and tools. Usually, decision-makers need to take into account not just a single criterion, but several different criteria and, therefore, multi-criteria decision-making (MCDM) approaches have been suggested for application in five of the published papers; the rest of the papers apply other research methods. Most approaches suggested decision models under uncertainty, proposing hybrid MCDM methods in combination with fuzzy or rough set theory, as well as D-numbers. The application areas of the proposed MCDM techniques mainly cover production/manufacturing engineering, logistics and transportation, and construction engineering and management. We hope that a summary of the Special Issue as provided here will encourage a detailed analysis of the papers included in the Printed Edition.

The machining of complex sculptured surfaces is a global technological topic, in modern manufacturing with relevance in both industrialized and emerging in countries, particularly within the moulds and dies sector whose applications include highly technological industries such as the automotive and aircraft industry. Machining of Complex Sculptured Surfaces considers new approaches to the manufacture of moulds and dies within these industries. The traditional technology employed in the manufacture of moulds and dies combined conventional milling and electro-discharge machining (EDM) but this has been replaced with high-speed milling (HSM) which has been applied in roughing, semi-finishing and finishing of moulds and dies with great success. Machining of Complex Sculptured Surfaces provides recent information on machining of complex sculptured surfaces including modern CAM systems and process planning for three and five axis machining as well as explanations of the advantages of HSM over traditional methods ranging from work piece precision and roughness to manual polishing following machining operations. Whilst primarily intended for engineering students and post graduates (particularly in the fields of mechanical, manufacturing or materials), Machining of Complex Sculptured Surfaces provides clear instructions on modern manufacturing; serving as a practical resource for all academics, researchers, engineers and industry professionals with interest in the machining of complex sculptured surfaces.

This book examines the interrelationship of representational methods and material systems as fundamental drivers of the design process. Identifying four primary categories of representational logics - point, line, surface, mass - each category is illustrated through four precedent projects that deploy iterative material sensibilities. As a collection, this text provides a comprehensive categorization of the architectural design process. Through the comprehensive definition of categorical typologies, it illustrates the collective capability of this conceptual methodology. By unpacking projects through their specific design devices, the collective analysis reveals the impact of material techniques and methods of representation as a generative tool. Broad in scope, it identifies and uniformly analyses some of the most significant projects from the last century, including: UK Pavilion Shanghai - Heatherwick Studio, Shanghai,China Gatehouse - Office dA, Beijing, China Maison Colonial - Jean Prouve, France/Africa de Young Museum - Herzog and de Meuron, California USA Montreal Expo 67 - Buckminster Fuller, Montreal, Canada Jean Marie Tjibou Cultural Center – RPBW, Noumea, Indonesia House III - Peter Eisenman, New York, USA Barcelona Pavilion - Mies van der Rohe, Barcelona, Spain Tel Aviv - Scott Cohen, Tel Aviv, Israel Los Manantiales - Felix Candella, Mexico City, Mexico Yokahama Terminal – FOA, Yokahama, Japan Pantheon, Rome, Italy Tres Grand Bibliotheque - Rem Koolhaas, OMA, Paris, France Brother Claus Field Chapel - Peter Zumthor, Switzerland Embryonic House- Greg Lynn Richly illustrated with consistent, clear and precise line drawings, the book presents a series of iconic precedents through a unique analytical and graphic sensibility.

It is commonplace that in our time science and technology cannot be mastered without the tools of mathematics; but the same applies to an ever growing extent to many domains of everyday life, not least owing to the spread of cybernetic methods and arguments. As a consequence, there is a wide demand for a survey of the results of mathematics, for an unconventional approach that would also make it possible to fill gaps in one's knowledge. We do not think that a mere juxtaposition of theorems or a collection of formulae would be suitable for this purpose, because this would over emphasize the symbolic language of signs and letters rather than the mathematical idea, the only thing that really matters. Our task was to describe mathematical interrelations as briefly and precisely as possible. In view of the overwhelming amount of material it goes without saying that we did not just compile details from the numerous text-books for individual branches: what we were aiming at is to smooth out the access to the specialist literature for as many readers as possible. Since well over 700000 copies of the German edition of this book have been sold, we hope to have achieved our difficult goal. Colours are used extensively to help the reader. Important definitions and groups of formulae are on a yellow background, examples on blue, and theorems on red.
