Lightning: Physics and Effects is the first book that covers essentially all aspects of lightning, including lightning physics, lightning protection and the interaction of lightning with a variety of objects and systems as well as with the environment. It is written in a style that will be accessible to the technical non-expert and is addressed to anyone interested in lightning and its effects. This will include physicists, engineers working in the power, communications, computer and aviation industries, meteorologists, atmospheric chemists, foresters, ecologists, physicians working in the area of electrical trauma and architects. This comprehensive reference volume contains over 300 illustrations, 70 tables containing quantitative information and a bibliography of more than 6000 references.

This book provides an in-depth analysis of tropical cyclones in the South Pacific, discussing both the characteristics and behaviors of tropical cyclones, and the impacts these storms have on island physical geography and landscape change. The second half of the book presents a whole field of important, new insight. A thorough examination of the links between climate and landscape are analyzed through detailed case studies based on 10 years of original research showing the importance of tropical cyclones for island physical environments, by triggering enormous responses in example river systems, slope processes, coastlines, and even island formation and/or destruction. A focus on the Pacific and the Pacific Islands cyclones is vital since a major area for research in climate change and climate extremes is located within this region. The South Pacific is one of the most important areas and factors of El Nino. It is the center of attention for climate change issues, such as ocean warming and sea level rise. As such, this book is an important and valuable addition to the existing literature on climate change.

A technical book introducing the cross-entropy method, a powerful tool for combinatorial optimization, Monte Carlo simulation, and machine learning. It explains how to generate random samples and update parameters to improve solutions in stochastic problems. Intended for engineers, mathematicians, and computer scientists.

Sensors are effective tools used to carry out cost-effective, fast, and reliable sensing for a wide range of applications. This volume presents a brief history behind sensing technology and highlights a broad range of biosensing techniques based on optical and electrochemical response methods. Starting from the traditional enzyme-based biosensing method to functionalized nanostructure-based sensors, this book also provides a detailed overview of some of the advanced sensing methodologies based on photonic crystal cavity-based sensing devices.

This book provides a pedagogical introduction to the perturbative and non-perturbative aspects of quantum chromodynamics (QCD). Introducing the basic theory and recent advances in QCD, it also reviews the historical development of the subject, covering pre-QCD ideas of strong interactions such as the quark and parton models, the notion of colours and the S-matrix approach. The author then discusses gauge theory, techniques of dimensional regularization and renormalization, deep inelastic scattering and hard processes in hadron collisions, hadron jets and e+e annihilations. Other topics include power corrections and the technologies of the Shifman-Vainshtein-Zakharov operating product expansion. The final parts of the book are devoted to modern non-perturbative approaches to QCD and the phenomenological aspects of QCD spectral sum rules. The book will be a valuable reference for graduate students and researchers in high-energy particle and nuclear physics, both theoretical and experimental.

Si hay algun fenomeno de la Fisica y la Astronomia que intriga y fascina al hombre, este es el de los agujeros negros, y fue Albert Einstein, cuando hace mas de cien anos elaboro la Teoria de la Relatividad, el primer cientifico que predijo su existencia como solucion a sus ecuaciones. Steven S. Gubser y Frans Pretorius arrojan luz sobre uno de los mayores misterios del universo a traves de ejemplos creativos y accesibles.

¿Como seria caer dentro de un agujero negro? ¿En que se parecen bailar un vals y contemplar una dualidad de cuerdas?La teoria de cuerdas trata de describir todas las fuerzas fundamentales de la naturaleza, hermanando conceptos tales como la gravedad y la mecanica cuantica en una sola teoria que, de momento, no esta aun probada. Rodeada de misterio y controversia, la teoria de cuerdas se vuelve menos opaca bajo la mirada de Steven S. Gubser, que nos la presenta de forma amena y entretenida.

Como la cantidad de información en Biología seexpande cada vez más, se hace cada vez másnecesario que los libros de texto reflejen el vastoconocimiento científico en concisos principios yconceptos duraderos. Como en ediciones anteriores,Biologia Molecular de la Celula, Sexta Edicion,cumple este objetivo con un texto claro y excelentepuesta al dia con las ultimas investigaciones enel campo de la biologia celular y proporciona unsolido apoyo tanto al profesor como al estudiante.

This is the first book devoted entirely to Particle Swarm Optimization (PSO), which is a non-specific algorithm, similar to evolutionary algorithms, such as taboo search and ant colonies.Since its original development in 1995, PSO has mainly been applied to continuous-discrete heterogeneous strongly non-linear numerical optimization, and it is thus used almost everywhere in the world. Its convergence rate also makes it a preferred tool in dynamic optimization.Particle Swarm Optimization explains the basic principles of the subject, particularly the concepts of particles, information link, memory and cooperation. Starting from a simple but efficient parametric version coded in a few lines, it shows how this can be gradually enhanced to lead to a fully adaptive version. All source programs are either included in the book or are downloadable for free.

This is the premier, single-source reference on redox biochemistry, a rapidly emerging field. This reference presents the basic principles and includes detailed chapters focusing on various aspects of five primary areas of redox biochemistry: antioxidant molecules and redox cofactors; antioxidant enzymes; redox regulation of physiological processes; pathological processes related to redox; and specialized methods. This is a go-to resource for professionals in pharmaceuticals, medicine, immunology, nutrition, and environmental fields and an excellent text for upper-level students.

Mark Tewdwr-Jones, Elisabeth Stahl-Biskup, Stahl-Biskup and SaezEleven chapters written by a group of international researchers provide an overview of the currently available information on the species-rich, diverse genus Thymus, including botany, taxonomy, chemistry, and pharmacology, taking into account such applied topics as field culture, in vitro culture, and selection; harvesting and processing; commercial products made from thyme; medicinal and non- medicinal uses; flavonoids and further polyphenols in the genus; and thyme as an herbal drug.
