Mohammad Elahinia Shape Memory Alloy Actuators. Design, Fabrication and Experimental Evaluation


This book provides a systematic approach to realizing NiTi shape memory alloy actuation, and is aimed at science and engineering students who would like to develop a better understanding of the behaviors of SMAs, and learn to design, simulate, control, and fabricate these actuators in a systematic approach. Several innovative biomedical applications of SMAs are discussed. These include orthopedic, rehabilitation, assistive, cardiovascular, and surgery devices and tools. To this end unique actuation mechanisms are discussed. These include antagonistic bi-stable shape memory-superelastic actuation, shape memory spring actuation, and multi axial tension-torsion actuation. These actuation mechanisms open new possibilities for creating adaptive structures and biomedical devices by using SMAs.

Tayyab Suratwala I. Materials Science and Technology of Optical Fabrication


Covers the fundamental science of grinding and polishing by examining the chemical and mechanical interactions over many scale lengths Manufacturing next generation optics has been, and will continue to be, enablers for enhancing the performance of advanced laser, imaging, and spectroscopy systems. This book reexamines the age-old field of optical fabrication from a materials-science perspective, specifically the multiple, complex interactions between the workpiece (optic), slurry, and lap. It also describes novel characterization and fabrication techniques to improve and better understand the optical fabrication process, ultimately leading to higher quality optics with higher yield. Materials Science and Technology of Optical Fabrication is divided into two major parts. The first part describes the phenomena and corresponding process parameters affecting both the grinding and polishing processes during optical fabrication. It then relates them to the critical resulting properties of the optic (surface quality, surface figure, surface roughness, and material removal rate). The second part of the book covers a number of related topics including: developed forensic tools used to increase yield of optics with respect to surface quality (scratch/dig) and fracture loss; novel characterization and fabrication techniques used to understand/quantify the fundamental phenomena described in the first part of the book; novel and recent optical fabrication processes and their connection with the fundamental interactions; and finally, special techniques utilized to fabricate optics with high damage resistance. Focuses on the fundamentals of grinding and polishing, from a materials science viewpoint, by studying the chemical and mechanical interactions/phenomena over many scale lengths between the workpiece, slurry, and lap Explains how these phenomena affect the major characteristics of the optic workpiece—namely surface figure, surface quality, surface roughness, and material removal rate Describes methods to improve the major characteristics of the workpiece as well as improve process yield, such as through fractography and scratch forensics Covers novel characterization and fabrication techniques used to understand and quantify the fundamental phenomena of various aspects of the workpiece or fabrication process Details novel and recent optical fabrication processes and their connection with the fundamental interactions Materials Science and Technology of Optical Fabrication is an excellent guidebook for process engineers, fabrication engineers, manufacturing engineers, optical scientists, and opticians in the optical fabrication industry. It will also be helpful for students studying material science and applied optics/photonics.

Ravi Birla Introduction to Tissue Engineering. Applications and Challenges


A comprehensive reference and teaching aid on tissue engineering—covering everything from the basics of regenerative medicine to more advanced and forward thinking topics such as the artificial liver, bladder, and trachea Regenerative medicine/tissue engineering is the process of replacing or regenerating human cells, tissues, or organs to restore or establish normal function. It is an incredibly progressive field of medicine that may, in the near future, help with the shortage of life-saving organs available through donation for transplantation. Introduction to Tissue Engineering: Applications and Challenges makes tissue engineering more accessible to undergraduate and graduate students alike. It provides a systematic and logical eight-step process for tissue fabrication. Specific chapters have been dedicated to provide in-depth principles for many of the supporting and enabling technologies during the tissue fabrication process and include biomaterial development and synthesis, bioreactor design, and tissue vascularization. The tissue fabrication process is further illustrated with specific examples for liver, bladder, and trachea. Section-coverage includes an overall introduction of tissue engineering; enabling and supporting technologies; clinical applications; and case studies and future challenges. Introduction to Tissue Engineering: Presents medical applications of stem cells in tissue engineering Deals with the effects of chemical stimulation (growth factors and hormones) Covers current disease pathologies and treatment options (pacemakers, prosthesis) Explains bioengineering, design and fabrication, and critical challenges during tissue fabrication Offers PowerPoint slides for instructors Features case studies and a section on future directions and challenges As pioneering individuals look ahead to the possibility of generating entire organ systems, students may turn to this text for a comprehensive understanding and preparation for the future of regenerative medicine.

Matthias Kohler Made by Robots. Challenging Architecture at a Larger Scale


In the next decade or so, the widespread adoption of robotics is set to transform the construction industry: building techniques will become increasingly automated both on- and off-site, dispensing with manual labour and enabling greater cost and operational efficiencies. What unique opportunities, however, does robotics afford beyond operational effectiveness explicitly for the practice of architecture? What is the potential for the serial production of non-standard elements as well as for varied construction processes? In order to scale up and advance the application of robotics, for both prefabrication and on-site construction, there needs to be an understanding of the different capabilities, and these should be considered right from the start of the design and planning process. This issue of AD showcases the findings of the Architecture and Digital Fabrication research module at the ETH Zurich Future Cities Laboratory in Singapore, directed by Fabio Gramazio and Matthias Kohler, which explores the possibilities of robotic construction processes for architecture and their large-scale application to the design and construction of high-rise buildings. Together with other contributors, such as Philippe Morel, Neri Oxman, François Roche and Antoine Picon, they also look at the far-reaching transformations starting to occur within automated fabrication: in terms of liberation of labour, entrepreneurship, the changing shape of building sites, in-situ fabrication and, most significantly, design. Contributors: Thomas Bock, Jelle Feringa, Philippe Morel, Neri Oxman, Antoine Picon and François Roche. ETH Zurich contributors: Michael Budig, Norman Hack, Willi Lauer and Jason Lim and Raffael Petrovic (Future Cities Laboratory), Volker Helm, Silke Langenberg and Jan Willmann.
