This textbook covers essential electrochemistry and materials science content and provides an extensive collection of examples in order to bridge the gap between engineering students' basic knowledge and the concrete skills they need to handle practical problems in fuel cells. The book starts with an introduction to the basic thermodynamics and electrochemistry principles and techniques in fuel cells. It subsequently discusses fuel cell operation principles, electrocatalysts, electrode materials, cell and system configuration and technologies in low-temperature fuel cells such as alkaline fuel cells and proton exchange membrane fuel cells, and in high-temperature fuel cells including solid oxide and molten carbonate fuel cells. Other energy conversion and storage technologies such as supercapacitors, batteries and electrolysis are also covered. A special chapter on laboratory experiments with fuel cells is also included, which can be conducted in conjunction with classroom teaching. Each chapter includes problems and exercises. The book provides students with an engineering background essential information on the basic thermodynamics, electrochemistry and materials of fuel cells, the most efficient and environmentally friend energy conversion technologies, all in a single book.

The multiple signal demixing and parameter estimation problems that result from the impacts of background noise and interference are issues that are frequently encountered in the fields of radar, sonar, communications, and navigation. Research in the signal processing and control fields has always focused on improving the estimation performance of parameter estimation methods at low SNR and maintaining the robustness of estimations in the presence of model errors. This book presents a universal and robust relaxation estimation method (RELAX), and introduces its basic principles and applications in the fields of classical line spectrum estimation, time of delay estimation, DOA estimation, and radar target imaging. This information is explained comprehensively and in great detail, and uses metaphors pertaining to romantic relationships to visualize the basic problems of parameter estimation, the basic principles of the five types of classical parameter estimation methods, and the relationships between these principles. The book serves as a reference for scientists and technologists in the fields of signal processing and control, while also providing relevant information for graduate students in the related fields.

This book is a comprehensive review of high-temperature polymer electrolyte membrane fuel cells (PEMFCs). PEMFCs are the preferred fuel cells for a variety of applications such as automobiles, cogeneration of heat and power units, emergency power and portable electronics. The first 5 chapters of the book describe rationalization and illustration of approaches to high temperature PEM systems. Chapters 6 - 13 are devoted to fabrication, optimization and characterization of phosphoric acid-doped polybenzimidazole membranes, the very first electrolyte system that has demonstrated the concept of and motivated extensive research activity in the field. The last 11 chapters summarize the state-of-the-art of technological development of high temperature-PEMFCs based on acid doped PBI membranes including catalysts, electrodes, MEAs, bipolar plates, modelling, stacking, diagnostics and applications.

Aesthetic Plastic Surgery in Asians: Principles and Techniques offers a comprehensive guide to all aspects of cosmetic surgery in Asians, focusing on the differences in surgical techniques and general principles when treating these patients. With special emphasis on minimally invasive techniques and minimization of scars, the book features contributions from surgeons in Asian regions who share their signature procedures and describe the latest innovations. The book is divided into ten parts. It begins with general principles and discusses the cultural and societal influence on Asian patients for cosmetic surgery as well as psychological and psychiatric considerations for Asian cosmetic patients. Next, the book covers facial rejuvenation with chapters on treatment for acne scars, laser skin resurfacing, fat grafting, and Botox. The book discusses the various approaches to face lift, including the classic face-lift and the short-scar method. A section on cosmetic surgery of the eyelid examines the special considerations in Asian eyelid surgery. It discusses upper and lower blepharoplasty, management of the sunken eyelid, and periorbital rejuvenation. A section on rhinoplasty covers alloplastic implants, autologous cartilage grafts, and primary open and closed rhinoplasty. The book also discusses cosmetic surgery of the ear and of the facial skeleton. The next chapters cover breast augmentation with implants, focusing on the transaxillary approach as well as the inframammary approach. The contributors discuss augmentation with conventional fat grafting and cell-assisted lipotransfer. Also covered are mastopexy, breast reduction, and breast reconstruction with pedicled TRAM flap. The final chapters cover abdominoplasty, liposuction of the trunk, buttock augmentation, calf reduction, and other procedures such as hair transplantation, penile enhancement, correction of varicose veins with endovascular laser, and correction of osmidrosis. Illustrated with over 2500 top-quality full-color drawings and photographs, and with three DVDs showcasing supplementary surgical techniques videos, this title is an absolutely indispensable resource for anyone involved in the aesthetic treatment of Asian patients.
