This book will be focused on the modeling and control of the DFIM based wind turbines. In the first part of the book, the mathematical description of different basic dynamic models of the DFIM will be carried out. It will be accompanied by a detailed steady-state analysis of the machine. After that, a more sophisticated model of the machine that considers grid disturbances, such as voltage dips and unbalances will be also studied. The second part of the book surveys the most relevant control strategies used for the DFIM when it operates at the wind energy generation application. The control techniques studied, range from standard solutions used by wind turbine manufacturers, to the last developments oriented to improve the behavior of high power wind turbines, as well as control and hardware based solutions to address different faulty scenarios of the grid. In addition, the standalone DFIM generation system will be also analyzed.
In The Invertebrate Tree of Life, Gonzalo Giribet and Gregory Edgecombe, leading authorities on invertebrate biology and paleontology, utilize phylogenetics to trace the evolution of animals from their origins in the Proterozoic to today. Phylogenetic relationships between and within the major animal groups are based on the latest molecular analyses, which are increasingly genomic in scale and draw on the soundest methods of tree reconstruction. Giribet and Edgecombe evaluate the evolution of animal organ systems, exploring how current debates about phylogenetic relationships affect the ways in which aspects of invertebrate nervous systems, reproductive biology, and other key features are inferred to have developed. The authors review the systematics, natural history, anatomy, development, and fossil records of all major animal groups, employing seminal historical works and cutting-edge research in evolutionary developmental biology, genomics, and advanced imaging techniques. Overall, they provide a synthetic treatment of all animal phyla and discuss their relationships via an integrative approach to invertebrate systematics, anatomy, paleontology, and genomics. With numerous detailed illustrations and phylogenetic trees, The Invertebrate Tree of Life is a must-have reference for biologists and anyone interested in invertebrates, and will be an ideal text for courses in invertebrate biology. A must-have and up-to-date book on invertebrate biology Ideal as both a textbook and reference Suitable for courses in invertebrate biology Richly illustrated with black-and-white and color images and abundant tree diagrams Written by authorities on invertebrate evolution and phylogeny Factors in the latest understanding of animal genomics and original fossil material" --Amazon.com.
Offering an alternative narrative of the conquest of the Incas, Gonzalo Lamana both examines and shifts away from the colonial imprint that still permeates most accounts of the conquest. Lamana focuses on a key moment of transition: the years that bridged the first contact between Spanish conquistadores and Andean peoples in 1531 and the moment, around 1550, when a functioning colonial regime emerged. Using published accounts and array of archival sources, he focuses on questions of subalternization, meaning making, copying, and exotization, which proved crucial to both the Spaniards and the Incas. On the one hand, he re-inserts different epistemologies into the conquest narrative, making central to the plot often-dismissed, discrepant stories such as books that were expected to talk and year-long attacks that could only be launched under a full moon. On the other hand, he questions the dominant image of a clear distinction between Inca and Spaniard, showing instead that on the battlefield as much as in everyday arenas such as conversion, market exchanges, politics, and land tenure, the parties blurred into each other in repeated instances of mimicry. Lamana’s redefinition of the order of things reveals that, contrary to the conquerors’ accounts, what the Spanairds achieved was a “domination without dominance.” This conclusion undermines common ideas of Spanish (and Western) superiority. It shows that casting order as a by-product of military action rests on a pervasive fallacy: the translation of military superiority into cultural superiority. In constant dialogue with critical thinking from different disciplines and traditions, Lamana illuminates how this new interpretation of the conquest of the Incas revises current understandings of Western colonialism and the emergence of still-current global configurations.
MUDÉJAR ART: Islamic Aesthetics in Christian Art reveals the fascinating exuberance of a unique cultural and artistic symbiosis that characterises Christian Spain after the Reconquista. The Mudéjars were Muslims allowed to stay in the reconquered territories. Their artists and artisans strongly influenced the culture and art of the new Christian kingdoms. In Aragon, Castille, Extremadura and Andalucía sumptuously decorated brick churches, monasteries and palaces illustrate perfectly the creative endurance of Islamic forms in Christian art between the 11th and 16th centuries in Spain. Thirteen Itineraries invite you to discover 124 museums, monuments and sites in Madrid, Guadalajara, Saragossa, Tordesillas, Toledo, Guadalupe and Seville (among others). With Index of Locations.
Dermatology is the science responsible for the study of the skin, mucous membranes (oral and genital) and cutaneous appendages, while dermatopathology focuses on its microscopic study. Although the two fields are closely related, in many cases the identification of dermatological diseases is mainly clinical and depends on the physician’s ability and experience. The purpose of this atlas, which collects over 900 clinical and histological photographs in high resolution, is to illustrate and describe the most frequent skin diseases on the basis of clinical cases. Offering a complete guide to the etiology, epidemiology, clinical features, histologic findings and diagnosis of the main skin diseases divided into three subgroups (inflammatory, infectious, or tumoral), it represents an invaluable resource for all medical students, residents, clinicians, and investigators learning dermatology.
