Offering complete and comprehensive coverage of modern sonar spectrum system analysis, Underwater Acoustics: Analysis, Design and Performance of Sonar provides a state-of-the-art introduction to the subject and has been carefully structured to offer a much-needed update to the classic text by Urick. Expanded to included computational approaches to the topic, this book treads the line between the highly theoretical and mathematical texts and the more populist, non-mathematical books that characterize the existing literature in the field. The author compares and contrasts different techniques for sonar design, analysis and performance prediction and includes key experimental and theoretical results, pointing the reader towards further detail with extensive references. Practitioners in the field of sonar design, analysis and performance prediction as well as graduate students and researchers will appreciate this new reference as an invaluable and timely contribution to the field. Chapters include the sonar equation, radiated, self and ambient noise, active sonar sources, transmission loss, reverberation, transducers, active target strength, statistical detection theory, false alarms, contacts and targets, variability and uncertainty, modelling detections and tactical decision aids, cumulative probability of detection, tracking target motion analysis and localization, and design and evaluation of sonars

Sonar and Underwater Acoustics brings together all the concepts necessary for designers and users of sonar systems. Unlike other books on this subject, which are often too specialized, this book is accessible to a wider audience. The first part focuses on the acoustic environment, antenna structures, and electric acoustic interface. The latter provides knowledge required to design, as well as the development and implementation of chain processes for an active sonar from the conditioning input to output processing. The reader will find a comprehensive range of all problems encountered in underwater acoustics for a sonar application, from physical phenomena governing the environment and the corresponding constraints, through to the technical definition of transducers and antennas, and the types of signal processing involved. In one section, measures in underwater acoustics are also proposed.

Wayne Corrigan y sus colegas de Suenos Dramaticos pueden emitir suenos directamente a tu mente mientras duermes. Pero cuando sucedio un fallo, Wayne tendra que encontrar la manera de rescatar a decenas de miles de gente incluyendo a la mujer que ama con toda su alma arrebatando el control del Sueno de un genio loco. En un futuro cercano, la emision de Suenos se ha convertido en el ultimo medio de entretenimiento. Con un Dreamcap mientras duermes podras ser enviado directamente a los Suenos de forma inconsciente, ofreciendote una experiencia de entretenimiento tan real que creeras estar alli en persona. Wayne Corrigan es un actor en Suenos Dramaticos, uno de los estudios mas pequenos en la zona de Los Angeles. Janet Meyers, la mujer de la que Wayne esta enamorado es demasiado timida para decirle nada. El tercer vertice es Vince Rondel, un genio del arte, llamado Sonador Maestro, con la imaginacion suficiente para crear mundos enteros dentro de las mentes y proyectarlas al publico. Vince es una super estrella del estudio, aunque no tiene pretensiones sobre ello. Tiene otros problemas, como si fuera una madre tirana y fanatica religiosa. Cuando ocurre un fallo, Wayne es llamado para entrar al Sueno que empezo Vince. Una vez dentro, encuentra que todo se ha vuelto loco y que la gente ha terminado siendo esclavizada por Vince, el cual parece ser querer autodestruirse. Ahora, con decenas de miles de televidentes incluyendo Janet, todo el publico estara en peligro de muerte o peor a menos que Wayne encuentre una manera para arrebatar el control del Sueno a Vince. ”Sin que los suenos te dominen” es una viaje salvaje e ingenioso a traves de la mente enferma de un loco.

Dengue virus is a member of the Flaviviridae family, which includes viruses associated with human diseases such as yellow fever, Japanese encephalitis and hepatitis C. Dengue fever is transmitted by mosquitoes, principally Aedes aegypti. There are four serotypes of dengue virus, of which DENV-2 has been the most prevalent in many recent epidemics. Following primary infection, lifelong immunity develops, preventing repeated assault by the same serotype. However, the non-neutralizing antibodies from a previous infection or maternally acquired antibodies are thought to form complexes with a different serotype during a subsequent infection and cause dengue haemorrhagic fever/dengue shock syndrome, which can be fatal. There is no treatment or vaccine available today that can combat this emerging and uncontrolled disease. This book features contributions from the world’s leading researchers working on dengue and related flaviviruses who examine the current state of the art in the molecular biology of the dengue virus. Particular emphasis is placed on the structure and function of the virus and the targeting of virus proteins by potential antiviral agents. The pathogenesis of dengue and dengue haemorrhagic fever are discussed in detail, especially the target cells and the specific receptors on these cells, thereby developing a clear overview of host and viral factors that contribute to dengue haemorrhagic fever. Finally, the book reviews the therapeutic options, paying particular attention to ways in which vector, host and environment can play a critical role in the spread of this disease. With dengue fever and other emerging viral diseases becoming increasingly prevalent around the world, this book provides valuable insight into the virus that causes this disease and potential ways to manage it. It is essential reading for all those working in tropical diseases, public health and virology. Praise from the reviews: «The book provides an excellent summary of dengue/flavivirus research and is important for individuals and institutions interested in emerging infectious diseases.» MICROBIOLOGY TODAY
