Today's photographic equipment allows amateurs to take pictures of the stars that far surpass images taken just a few decades ago by even the largest observatories-and this book will teach you how. Author and world-renowned astrophotographer Thierry Legault teaches the art and techniques of astrophotography: from simple camera-on-tripod night-scene imaging of constellations, star trails, eclipses, artificial satellites, and polar auroras to more intensive astrophotography using specialized equipment for lunar, planetary, solar, and deep-sky imaging. Legault shares advice on equipment and guides you through techniques to capture and process your images to achieve spectacular results. Astrophotography provides the most thorough treatment of the topic available. This large-format, richly illustrated book is intended for all sky enthusiasts-newcomers and veterans alike. Learn how to: Select the most useful equipment: cameras, adapters, filters, focal reducers/extenders, field correctors, and guide telescopes Set up your camera (digital, video, or CCD) and your lens or telescope for optimal results Plan your observing sessions Mount the camera on your telescope and focus it for razor-sharp images Polar-align your equatorial mount and improve tracking for pin-point star images Make celestial time-lapse videos Calculate the shooting parameters: focal length and ratio, field of view, exposure time, etc. Combine multiples exposures to reveal faint galaxies, nebulae details, elusive planetary structures, and tiny lunar craters Adjust contrast, brightness, light curves, and colors Postprocess your images to fix defects such as vignetting, dust shadows, hot pixels, uneven background, and noise Identify problems with your images and improve your results
2G/GSM and 3G/UMTS are key mobile communication technologies, chosen by more than 2 billion people around the world. In order to adapt to new services, increasing demand for user bandwidth, quality of service and requirements for network convergence, major evolutions are introduced in 3G network standard. Evolved Packet System (EPS) presents the EPS evolution of the 3G/UMTS standard introduced by the 3rd Generation Partnership Project (3GPP) standard committee. This new topic is looked at from a system perspective, from the radio interface to network and service architecture. Hundreds of documents being issued by Standard organisations are summarised in one book to allow the reader to get an accessible comprehensive view of EPS evolution. Proposes a system view of Evolved UMTS, from the radio to Core and service architecture Gives a comprehensive and global view of the system that technical specifications do not provide Describes the new system as well as the inheritance and migration from 2G/GSM and 3G/UMTS Written by experts in the field who specialise in two complementary but very different technical domains (i.e. "radio interface" and "network architecture") Contains many figures and examples for better understanding. This book is essential for industry professionals in the telecommunication business, telecommunication system architects and designers, product manufacturers and operators and postgraduate students.

Un gouvernement prend son peuple en otage, l'affame, inonde le monde de photos terribles et réclame de l'argent. L'opinion publique mondiale a réagi immédiatement, avec générosité, bravo ! Mais aussi avec aveuglement. André Glucksmann et Thierry Wolton révèlent les dessous de la plus grande opération d'aide et de charité qu'ait connue l'histoire humaine. Comment la dictature éthiopienne a laissé venir la famine, comment elle organisa et mit en scène l'information et pourquoi les institutions internationales, parfaitement au courant, couvrent les scandales et les crimes des autorités communistes locales. Informations, émotions, mobilisations, c'est sur le petit écran que se noue notre rapport à l'autre : un milliard cinq cents millions de Terriens ont regardé en même temps et les terribles images de la famine et la retransmission du plus grand concert pop et charitable. André Glucksmann et Thierry Wolton essaient de définir le principe d'une morale de l'extrême urgence qui fonde la nouvelle solidarité électronique. Dans la guerre des images, les démocraties sont en retard ; elles subissent les mises en scène terroristes sans interroger la stratégie qui les prémédite. L'URSS a pris de l'avance en Afrique, elle fournit les munitions, tandis que l'Occident livre le blé. L'Afrique rouge est bien partie.
Le père avait tout compris, il a raccroché à quarante cinq ans. Bien vu, il est mort à cinquante neuf. Quatorze ans de retraite dans sa cabane avec son herbe haute...et ses quatre fraises. Le temps, il l'aura suspendu à sa façon, en grand philosophe, au moment ou il pouvait encore boire son canon en regardant avec son sourire et son oeil clair tout ce qui ne le fatiguait pas: un oiseau qui passe, un frigo qui fait du frais...l'herbe qui pousse...Bref, un scientifique qui économisait son coeur souvent sollicité par un refus absolu de toutes formes de régimes.
This book describes the implementation of multilevel methods in a dynamical context, with application to the numerical simulation of turbulent flows. The general ideas for the algorithms presented stem from dynamical systems theory and are based on the decomposition of the unknown function into two or more arrays corresponding to different scales in the Fourier space. This timely monograph should appeal to graduate students and researchers alike, providing a background for applied mathematicians as well as engineers.
This book offers the reader the keys for a successful understanding, integration and usage of satellite systems in addition to next generation terrestrial networks. The DVB-S2/RCS system is used to illustrate the integration challenges. The presentation uses a system approach, i.e. it tackles the terrestrial and satellite telecommunication systems’ complexity with a high level approach, focusing on the systems’ components and on their interactions. Several scenarios present the different paths that can be followed for the integration of satellite systems in terrestrial networks. Quality of Service management techniques in terrestrial and satellite systems and the solutions to help them to interoperate are provided. Inter-system mobility solutions and performance problems are then addressed. The solutions proposed in this book have been developed within the framework of European and French funded research projects and tested with simulated or real testbeds.
Applied Signal Processing: A MATLAB-Based Proof of Concept benefits readers by including the teaching background of experts in various applied signal processing fields and presenting them in a project-oriented framework. Unlike many other MATLAB-based textbooks which only use MATLAB to illustrate theoretical aspects, this book provides fully commented MATLAB code for working proofs-of-concept. The MATLAB code provided on the accompanying online files is the very heart of the material. In addition each chapter offers a functional introduction to the theory required to understand the code as well as a formatted presentation of the contents and outputs of the MATLAB code. Each chapter exposes how digital signal processing is applied for solving a real engineering problem used in a consumer product. The chapters are organized with a description of the problem in its applicative context and a functional review of the theory related to its solution appearing first. Equations are only used for a precise description of the problem and its final solutions. Then a step-by-step MATLAB-based proof of concept, with full code, graphs, and comments follows. The solutions are simple enough for readers with general signal processing background to understand and they use state-of-the-art signal processing principles. Applied Signal Processing: A MATLAB-Based Proof of Concept is an ideal companion for most signal processing course books. It can be used for preparing student labs and projects.
The crisis has highlighted the importance of setting up macro-prudential oversight frameworks, having effective macro-prudential instruments in place to be called upon to mitigate growing financial imbalances as needed. We develop a new approach using the euro area Bank Lending Survey to assess the effectiveness of macro-prudential policies in containing credit growth and house price appreciation in mortgage markets. We find instruments targeting the cost of bank capital most effective in slowing down mortgage credit growth, and that the impact is transmitted mainly through price margins, the same banking channel as monetary policy. Limits on loan-to-value ratios are also effective, especially when monetary policy is excessively loose.
