The long-awaited second edition of this well-received textbook gives a thorough introduction to observational astronomy. Starting with the basics of positional astronomy and systems of time, it continues with charts and catalogs covering both historically important publications and modern electronic databases. The book builds on a fundamental discussion of the basics of light and the effects of the atmosphere on astronomical observations. Chapters include discussions of optical telescopes, detectors, photometry, variable stars, astrometry, spectroscopy, and solar observations. This edition contains new discussions of measurements with CCDs and appendices give basic statistical methods, useful astronomical software and websites, and sources of accurate time-calibration signals. Observational Astronomy is the perfect textbook for upper level undergraduate or beginning graduate courses on astronomy. Examples based on real astronomical data are placed throughout the text. Each of the well-illustrated chapters is supported by a set of graduated problems and suggestions for further reading.

Advanced Electromagnetic Wave Propagation Methods

This textbook provides a solid foundation into many approaches that are used in the analysis of advanced electromagnetic wave propagation problems. The techniques discussed are essential to obtain closed-form solutions or asymptotic solutions and meet an existing need for instructors and students in electromagnetic theory. The book covers various advanced mathematical methods used in the evaluation of the electromagnetic fields in rectangular, cylindrical and spherical geometries. The mathematics of special functions (i.e., Bessel, Hankel, Airy, Legendre, Error, etc.) are covered in depth, including appropriate Appendices. The author takes particular care to provide detailed explanations of auxiliary potentials, Hertz’s vectors, Debye potentials, as well as the use of Green functions, the Watson transformation and the method of steepest descent in the solution of electromagnetic problems. Overall, Advanced Electromagnetic Wave Propagation Methods is a good source for the many skills required in obtaining closed form and asymptotic solution, which in many instances cannot be obtained using computer codes of Maxwell’s equations. Thus, it provides an excellent training for preparing graduate students in their research work. This book is intended for a graduate course in electromagnetic theory for students in electrical engineering. Students in physics and professionals will also find it appropriate and useful. Provides a comprehensive and unified treatment of radiation and propagation problems Presents a detailed explanation in the use of Green functions, the Watson transformation and the method of steepest descent as they apply to electromagnetic problems Demonstrates various advanced mathematical techniques used in the evaluation of the electromagnetic fields Details how to formulate and obtain a closed-form solution or an asymptotic solution Includes appendices for Bessel, Legendre, Airy and Error functions

Nos encontramos ante un n#65533;mero dedicado a la transparencia desde diferentes prismas. Hemos decidido hablar sobre esta tem#65533;tica con un objetivo bifocal que apunta por una parte al an#65533;lisis cr#65533;tico de nuestro contexto y, por otra, a la autocr#65533;tica. En esta ocasi#65533;n, volvemos a publicar una investigaci#65533;n emp#65533;rica. La misma ha sido elaborada por Jaume Hombrado, que nos muestra a trav#65533;s del an#65533;lisis de redes sociales f#65533;sicas c#65533;mo es posible la aplicaci#65533;n de metodolog#65533;as de otras ramas de conocimiento en Criminolog#65533;a, a la par que vincula su investigaci#65533;n a los famosos Panam#65533; Papers. Por otra parte, Guillermo Gonz#65533;lez nos ha tra#65533;do una entrevista realizada a Jes#65533;s Lizcano, director de Transparencia Internacional en Espa#65533;a, en la que nos habla de la transparencia como arma de destrucci#65533;n masiva contra la corrupci#65533;n, mas limitada por una multiplicidad de factores trasversales que perjudican su eficacia. Carlota Barrios nos da unas pinceladas n#65533;tidas sobre el ejercicio de la transparencia en el lienzo de una deontolog#65533;a profesional fundada en una jerarqu#65533;a piramidal de tres cuerpos. El art#65533;culo de Jose Servera versa sobre el periodismo participativo, o citadino, desde sus diferentes niveles como respuesta a la crisis period#65533;stica que est#65533;n sufriendo los mass media ante el desmantelamiento de la objetividad en favor de las influencias de lobbies, as#65533; como las repercusiones que el ejercicio de dicho movimiento conlleva. Por #65533;ltimo, Ra#65533;l Caballero profundiza en la prevenci#65533;n en materia de siniestralidad vial, evaluando el factor humano intr#65533;nseco a esta y proponiendo un modelo m#65533;s eficaz de intervenci#65533;n basado en el conductor.

Oscillators are an important component in today's RF and microwave systems, and practitioners in the field need to know how to design oscillators for stability and top performance. Offering engineers broader coverage than other oscillator design books on the market, this comprehensive resource considers the complete frequency range, from low-frequency audio oscillators to more complex oscillators found at the RF and microwave frequencies. Packed with over 1,200 equations, the book gives professionals a thorough understanding of the principles and practice of oscillator circuit design and emphasizes the use of time-saving CAD (computer aided design) simulation techniques. From the theory and characteristics of oscillators, to the design of a wide variety of oscillators (including tuned-circuit, crystal, negative-resistance, and relaxation oscillators), this unique book is a one-stop reference practitioners can turn to again and again when working on their challenging projects in this field.

Earth. The Final FrontierContrary to popular belief, Earth is not an insignificant blip on the universe’s radar. Our world proves anything but average in Guillermo Gonzalez and Jay W. Richards’ The Privileged Planet: How Our Place in the Cosmos Is Designed for Discovery.But what exactly does Earth bring to the table? How does it prove its worth among numerous planets and constellations in the vastness of the Milky Way? In The Privileged Planet, you’ll learn about the world’s: life-sustaining capabilities water and its miraculous makeup protection by the planetary giantsAnd how our planet came into existence in the first place.
