O aumento do consumo de fontes de energia baseadas em combust veis f sseis, como a gasolina, no setor dos transportes, devido indisponibilidade de outras fontes de energia sustent veis, renov veis e ecol gicas, levou a problemas como o aquecimento global e as altera es clim ticas. Os biocombust veis de primeira gera o produzidos a partir de culturas alimentares, como milho e cana-de-a car, e os biocombust veis de segunda gera o produzidos a partir de mat rias-primas lignocelul sicas n o conseguiram satisfazer a procura global de bioetanol devido sua utiliza o como alimento, ao elevado pre o destas mat rias-primas e grande quantidade de terra utilizada para o seu cultivo. No entanto, o biocombust vel de terceira gera o derivado de algas parece ser uma fonte de energia renov vel sustent vel, pois as algas s o comuns na natureza e t m a capacidade de acumular grandes quantidades de amido e celulose, que podem ser convertidos em bioetanol.
This book focusses on the spacer engineering aspects of novel MOS-based device–circuit co-design in sub-20nm technology node, its process complexity, variability, and reliability issues. It comprehensively explores the FinFET/tri-gate architectures with their circuit/SRAM suitability and tolerance to random statistical variations.

This book contains detailed information on the types, structure, fabrication, and characterization of organic solar cells (OSCs). It discusses processes to improve efficiencies and the prevention of degradation in OSCs. It compares the cost-effectiveness of OSCs to those based on crystalline silicon and discusses ways to make OSCs more economical. This book provides a practical guide for the fabrication, processing, and characterization of OSCs and paves the way for further development in OSC technology.
This book is meant for a wide range of graduate students, who wishes to learn the basic concepts of Genetic Algorithms. It can also be meant for programmers, researchers and experts whose work is based on optimization techniques. The basic concepts of Genetic Algorithms are dealt in detail with the relevant information and knowledge available for understanding the optimization process. The various operators involved for Genetic Algorithm operation are explained. Genetic Algorithms, at present, is a hot topic among academicians, researchers and program developers. This book can be used as a ready reference materials for graduate students and research scholars.
This book will be useful for graduates, post-graduates, and research students as well various programmers, who either have an interest in this subject or have this subject as a part of their curriculum. The reader can be a beginner or an advanced learner.Fuzzy Logic, at present is a hot topic. It is based on the observation that people make decisions based on imprecise and non-numerical information. Fuzzy models or sets are mathematical means of representing vagueness and imprecise information (hence the term fuzzy). These models have the capability of recognizing, representing, manipulating, interpreting, and utilizing data and information that are vague and lack certainty. The various operators involved for Fuzzy Logic operation are explained. The basic concepts of Fuzzy Logic are discussed in detail using various solved examples. The applications of Fuzzy Logic are also dealt to make the readers understand the concept of Fuzzy Logic. This book can be used as a ready reference material for graduate students and research scholars.
