The Assistant Principal
This first-of-its-kind work addresses the needs of students, instructors, and practitioners, helping new, experienced, and prospective assistant principals develop the skills they need most.
A revelatory exploration of the hottest trend in technology and the dramatic impact it will have on the economy, science, and society at large. Which paint color is most likely to tell you that a used car is in good shape? How can officials identify the most dangerous New York City manholes before they explode? And how did Google searches predict the spread of the H1N1 flu outbreak? The key to answering these questions, and many more, is big data. “Big data” refers to our burgeoning ability to crunch vast collections of information, analyze it instantly, and draw sometimes profoundly surprising conclusions from it. This emerging science can translate myriad phenomena—from the price of airline tickets to the text of millions of books—into searchable form, and uses our increasing computing power to unearth epiphanies that we never could have seen before. A revolution on par with the Internet or perhaps even the printing press, big data will change the way we think about business, health, politics, education, and innovation in the years to come. It also poses fresh threats, from the inevitable end of privacy as we know it to the prospect of being penalized for things we haven’t even done yet, based on big data’s ability to predict our future behavior. In this brilliantly clear, often surprising work, two leading experts explain what big data is, how it will change our lives, and what we can do to protect ourselves from its hazards. Big Data is the first big book about the next big thing. www.big-data-book.com

The European Solar Radiation Atlas
This atlas offers a unique instrument dedicated to the knowledge and exploitation of the solar resources for Europe in a broad sense, from Ural to Azores and from Northern Africa to Polar Circle. It is a powerful tool for architects, engineers, meteorologists, agronomists, local authorities, tourism professionals, as well as researchers and students. It covers the period 1981-1990. It offers fundamental knowledge on the solar radiation available at groundlevel, which is of primary importance for both the life and the climate (including the ocean) since it is the primary source of energy on Earth by far. This book describes the course of the Sun across the sky as it varieties throughout the year and with the geographical location. The interactions of the solar radiation with the atmosphere and its components (haze, turbidity, clouds, etc.), and the separation of the radiation into the direct and diffuse parts are discussed. The importance of the solar radiation in various domains is presented, with an emphasis on solar engineering, where solar energy is used to provide electricity in photovoltaics systems, to supply hot water or heat houses. Ground radiation measurement techniques and instruments are described. Satellite images are also used. They are combined with ground measurements to provide a synoptic view of the distribution of the solar radiation over Europe. The structure of the database and its main applications are described. 26 coloured maps (ten years average 1981-90) describe the solar radiation and its direct and diffuse parts. They also detail the changes with time. The value of the atlas can be usefully extended by using it in conjunction with the complementary volume and CD-ROM called : The European Solar Radiation Atlas - vol. 2: database and exploitation software, also published by Les Presses de l'Ecole des Mines. The database offers spatial (every 10 km approximately) and temporal knowledge for different timescales (front climatological means -more than 700 stations- to hourly values -7 stations-) on the solar resources: irradiation (global and its components), sunshine duration, as well as air temperatures, precipitation, water vapour pressure, air pressure in a number of stations. The software uses the database in either a "map" or a "station" mode at user choice. Once a station been selected, the program looks for all the data available for this station. The software includes algorithms covering the following fields: solar geometry, optical properties of the atmosphere, estimation of hourly slope irradiation under cloudless skies, estimation of solar irradiation values (going from daily to hourly values, conversion from horizontal to titled surfaces), spectral irradiance, illuminance, daily mean profiles of temperature and other statistical quantities (central moments, extremes, probability, cumulative probability and utilizability curves). Graphics can be displayed in 2 or 3 dimensions. Some applications studies on solar engineering can be performed too. This Atlas bas been realised on behalf of the European Commission, by a team led by the company GET (Jülich, Germany), and comprising the Deutsche Wetterdienst (Hamburg, Germany), Armines/Ecoles des Mines de Paris et de Nantes (France), Instituto Nacional de Engenharia e Tecnologia Industrial (Lisbon, Portugal), the Technical University of Lyngby (Denmark), the World Radiation Data Centre (Saint-Petersburg, Russia), and Institut Royal de Météorologie (Brussels, Belgium), John Page (Sheffield, United Kingdom) and Robert Dogniaux (Brussels, Belgium) acting as advisors.
