One of the major challenges for modern organizations is the management of individual and collective knowledge, which is at the root of specific practices designed to optimize knowledge acquisition, maintenance and application. There are, however, still a disproportionately low number of studies focused on the structure and nature of knowledge. This book tackles the subject of daily knowledge: the knowledge related to everyday tasks. How does this knowledge present itself in the mind? How do we acquire and preserve it? To answer these questions, the authors explore a number of techniques which help to keep track of information produced in collaborative activity and extract knowledge by aggregating these traces.

Earthquake Occurrence provides the reader with a review of algorithms applicable for modeling seismicity, such as short-term earthquake clustering and pseudo-periodic long-term behavior of major earthquakes. The concept of the likelihood ratio of a set of observations under different hypotheses is applied for comparison among various models. In short-term models, known by the term ETAS, the occurrence space and time rate density of earthquakes is modeled as the sum of two terms, one representing the independent or spontaneous events, and the other representing the activity triggered by previous earthquakes. Examples of the application of such algorithms in real cases are also reported. Dealing with long-term recurrence models, renewal time-dependent models, implying a pseudo-periodicity of earthquake occurrence, are compared with the simple time-independent Poisson model, in which every event occurs regardless of what has occurred in the past. The book also introduces a number of computer codes developed by the authors over decades of seismological research.

A practical reference to support choosing, customising and handling the best PV simulation solution This comprehensive guide surveys all available models for simulating a photovoltaic (PV) generator at different levels of granularity, from cell to system level, in uniform as well as in mismatched conditions. Providing a thorough comparison among the models, engineers have all the elements needed to choose the right PV array model for specific applications or environmental conditions matched with the model of the electronic circuit used to maximize the PV power production. Key features: Multiple mathematical models are given for different application requirements. The shading effect is taken into account to improve the model accuracy. Procedures for parameter identification of the PV model are analysed and compared. Mathematical manipulations are introduced to some models to reduce their calculation time. The electronic interface effect on the power chain is analysed. Analytical expressions are used to design and control the power converter driving the PV field. The book is an essential reference for R&D in the PV industry; designers of power converters for PV; PV systems designers; and practicing engineers.

The publication of this fourth edition, more than ten years on from the publication of Radiation Therapy Physics third edition, provides a comprehensive and valuable update to the educational offerings in this field. Led by a new team of highly esteemed authors, building on Dr Hendee’s tradition, Hendee’s Radiation Therapy Physics offers a succinctly written, fully modernised update. Radiation physics has undergone many changes in the past ten years: intensity-modulated radiation therapy (IMRT) has become a routine method of radiation treatment delivery, digital imaging has replaced film-screen imaging for localization and verification, image-guided radiation therapy (IGRT) is frequently used, in many centers proton therapy has become a viable mode of radiation therapy, new approaches have been introduced to radiation therapy quality assurance and safety that focus more on process analysis rather than specific performance testing, and the explosion in patient-and machine-related data has necessitated an increased awareness of the role of informatics in radiation therapy. As such, this edition reflects the huge advances made over the last ten years. This book: Provides state of the art content throughout Contains four brand new chapters; image-guided therapy, proton radiation therapy, radiation therapy informatics, and quality and safety improvement Fully revised and expanded imaging chapter discusses the increased role of digital imaging and computed tomography (CT) simulation The chapter on quality and safety contains content in support of new residency training requirements Includes problem and answer sets for self-test This edition is essential reading for radiation oncologists in training, students of medical physics, medical dosimetry, and anyone interested in radiation therapy physics, quality, and safety.

Eine bunte und uberraschende Abenteuerreise durch die faszinierenden Weiten des Chemie-Universums: Wie erklart die Chemie die Entstehung des Lebens, wie hat sie die Welt verandert und wie lassen sich die drangenden Probleme unserer Zeit mit ihrer Hilfe losen? In zwolf Kapiteln geben uns ausgesuchte Spezialisten, Chemiker und Chemikerinnen einen Einblick in die Chemie als au?erst kreative und verantwortungsbewusste Wissenschaft. Viele praktische Beispiele, Produkte und Anwendungen zeigen das Potential der Chemie auf. So erfahrt man etwa, dass eine moderne Energie- und Rohstoffversorgung ohne Chemie weder denkbar noch machbar ist und welche Bedeutung die Chemie fur die moderne Informationstechnologie hat. Ein besonderes Augenmerk wird darauf gerichtet, welche Rolle die Chemie bei aktuellen und zukunftigen Herausforderungen unserer Gesellschaft spielt: Die ungebrochen wachsende Weltbevolkerung, die drohende Knappheit von Nahrung und Wasser, die Gesundheitsvorsorge und Heilung von Krankheiten, der ansteigende Energieverbrauch sowie der Erhalt unserer Lebensqualitat – als stark interdisziplinar orientierte Wissenschaft schafft die Chemie die Grundlagen, um diese dringenden Probleme unserer Zeit nachhaltig anzugehen. Quo vadis Chemie? In diesem Buch wird kritisch und fachkundig diskutiert, wie sich die Chemie entwickeln muss, um diesen Aufgaben gerecht zu werden. Heute gelingt schon vieles, dennoch werden neue Denkansatze und innovative Prozesse und Produkte fur die Zukunft gebraucht. Ohne Chemie ist keine Losung moglich. Ein spannendes und informatives Buch fur alle, die sich fur Chemie und fur die Welt, in der wir leben, interessieren und gerne wissen mochten, welche Rolle die Chemie nicht nur heute wahrnimmt, sondern vor allem zukunftig spielen sollte.
