Available in PDF, EPUB and Kindle. Book excerpt: The high level of innovation currently transforming our society and its technological dynamics can be seen as a second wave of innovation of the third technological system, which emerged in the late 1970s. This book discusses the concept of technological systems, focusing on the tools used for formalizing the organization of technology in society and its dynamics of evolution. The author uses these tools to characterize the contemporary technological system and to model its specific dynamics. In doing so, he raises questions about the continuity of the current technological system, and its capacity to generate powerful innovatory movements.

Book excerpt: Notes (de cours) de l’année 2014 dans le domaine Physique - Optique, note: -, , langue: Français, résumé: Certes Einstein avait prévu le phénomène d’émission stimulée dès 1927, mais il a fallu attendre jusqu’en 1960 pour que la première réalisation du laser puisse voir le jour. Ce fut sous la forme du maser optique à rubis construit par Maiman. Environ cinquante ans après leur découverte, les lasers se révèlent toujours un axe de recherche à la fois prometteur et actif dont les applications sont de plus en plus pertinentes et de grand intérêt. Ceci a constitué la motivation principale qui nous a incité à rédiger ce manuel de cours qui s’articule autour des fondamentaux du laser. Nous nous sommes attachés à présenter un contenu simple qui met en relief les notions élémentaires de la physique du laser sans renter dans des détails complexes qui risquent de nuire au message principal que nous voulons transmettre essentiellement aux étudiants débutants en l’occurrence ceux de la licence. Ainsi, nous avons évité les calculs fastidieux qui caractérisent en général des formalismes mathématiques laborieux. Notre démarche consiste donc à vulgariser la présentation de ce cours afin qu’il soit facile d’accès. En bref, ce manuel offre le tout premier contact avec les propriétés du laser et ouvre la voie pour approfondir amplement ses connaissances à ce sujet. Le chapitre 1 est dédié à des généralités au sujet de la lumière laser. Le chapitre 2 présente les mécanismes d’émission spontanée, d’absorption et d’émission stimulée. Dans le Chapitre 3, nous focalisons l’intérêt sur le principe de base du laser. Le Chapitre 4 décortique chacun des éléments qui constituent le dispositif laser. Le Chapitre 5 donne et explique la nature mathématique du faisceau laser en mettant en relief les propriétés de son extension spatiale. Dans le Chapitre 6, il est question de passer en revue les différents types des lasers. Enfin, le Chapitre 7 est consacré à la présentation de quelques applications des lasers. Mots clés: Laser; Emission stimulée; Principe de fonctionnement; Caractéristiques du dispositif laser, Faisceau gaussien; Types du laser; Applications.

Download or read book Discovery of Grounded Theory written by Barney Glaser and published by Routledge. This book was released on 2017-07-05 with total page 372 pages. Available in PDF, EPUB and Kindle. Book excerpt: Most writing on sociological method has been concerned with how accurate facts can be obtained and how theory can thereby be more rigorously tested. In The Discovery of Grounded Theory, Barney Glaser and Anselm Strauss address the equally Important enterprise of how the discovery of theory from data?systematically obtained and analyzed in social research?can be furthered. The discovery of theory from data?grounded theory?is a major task confronting sociology, for such a theory fits empirical situations, and is understandable to sociologists and laymen alike. Most important, it provides relevant predictions, explanations, interpretations, and applications. In Part I of the book, "Generation Theory by Comparative Analysis," the authors present a strategy whereby sociologists can facilitate the discovery of grounded theory, both substantive and formal. This strategy involves the systematic choice and study of several comparison groups. In Part II, The Flexible Use of Data," the generation of theory from qualitative, especially documentary, and quantitative data Is considered. In Part III, "Implications of Grounded Theory," Glaser and Strauss examine the credibility of grounded theory. The Discovery of Grounded Theory is directed toward improving social scientists' capacity for generating theory that will be relevant to their research. While aimed primarily at sociologists, it will be useful to anyone Interested In studying social phenomena?political, educational, economic, industrial? especially If their studies are based on qualitative data.

Download or read book Lake Pavin written by Télesphore Sime-Ngando and published by Springer. This book was released on 2016-10-31 with total page 422 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book represents the first multidisciplinary scientific work on a deep volcanic maar lake in comparison with other similar temperate lakes. The syntheses of the main characteristics of Lake Pavin are, for the first time, set in a firmer footing comparative approach, encompassing regional, national, European and international aquatic science contexts. It is a unique lake because of its permanently anoxic monimolimnion, and furthermore, because of its small surface area, its substantially low human influence, and by the fact that it does not have a river inflow. The book reflects the scientific research done on the general limnology, history, origin, volcanology and geological environment as well as on the geochemistry and biogeochemical cycles. Other chapters focus on the biology and microbial ecology whereas the sedimentology and paleolimnology are also given attention. This volume will be of special interest to researchers and advanced students, primarily in the fields of limnology, biogeochemistry, and aquatic ecology.

Available in PDF, EPUB and Kindle. Book excerpt: CERN, the European Laboratory for particle physics, regularly makes the news. What kind of research happens at this international laboratory and how does it impact people's daily lives? Why is the discovery of the Higgs boson so important? Particle physics describes all matter found on Earth, in stars and all galaxies but it also tries to go beyond what is known to describe dark matter, a form of matter five times more prevalent than the known, regular matter. How do we know this mysterious dark matter exists and is there a chance it will be discovered soon? About sixty countries contributed to the construction of the gigantic Large Hadron Collider (LHC) at CERN and its immense detectors. Dive in to discover how international teams of researchers work together to push scientific knowledge forward. Here is a book written for every person who wishes to learn a little more about particle physics, without requiring prior scientific knowledge. It starts from the basics to build a solid understanding of current research in particle physics. A good dose of curiosity is all one will need to discover a whole world that spans from the infinitesimally small and stretches to the infinitely large, and where imminent discoveries could mark the dawn of a huge revolution in the current conception of the material world.
