Synopsis Conception et optimisation de convertisseurs statiques pour l'électronique de puissance by : Chérif Larouci
L'objectif de nos travaux de thèse est de réaliser une démarche d'optimisation des convertisseurs statiques la plus générale possible en s'appuyant sur des modèles analytiques et un environnement d'optimisation adéquat. Pour ce faire, nous avons choisi une structure flyback en absorption sinusoïdale comme un support significatif d'étude car elle regroupe la plupart des aspects qui intéressent le concepteur des convertisseurs statiques actuels (volume, pertes, compatibilité électromagnétique CEM, thermiques...). Ce processus d'optimisation réclame la mise au point de modèles capables de réaliser le compromis indispensable précision-rapidité de calcul. Ainsi, des modèles analytiques et des outils dédiés à l'optimisation ont été développés et intégrés dans une démarche d'optimisation sous contraintes. Les résultats de mesure viennent valider cette procédure d'optimisation.

Synopsis Inelastic Analysis of Structures under Variable Loads by : Dieter Weichert
The question whether a structure or a machine component can carry the applied loads, and with which margin of safety, or whether it will become unserviceable due to collapse or excessive inelastic deformations, has always been a major concern for civil and mechanical engineers. The development of methods to answer this technologically crucial question without analysing the evolution of the system under varying loads, has a long tradition that can be traced back even to the times of emerging mechanical sciences in the early 17th century. However, the scientific foundations of the theories underlying these methods, nowadays frequently called "direct", were established sporadically in the Thirties of the 20th century and systematically and rigorously in the Fifties. Further motivations for the development of direct analysis techniques in applied mechanics of solids and structures arise from the circumstance that in many engineering situations the external actions fluctuate according to time histories not a priori known except for some essential features, e.g. variation intervals. In such situations the critical events (or "limit states") to consider, besides plastic collapse, are incremental collapse (or "ratchetting") and alternating plastic yielding, namely lack of "shakedown". Non evolutionary, direct methods for ultimate limit state analysis of structures subjected to variably-repeated external actions are the objectives of most papers collected in this book, which also contains a few contributions on related topics.

Synopsis Power Electronics Semiconductor Devices by : Robert Perret
This book relates the recent developments in several key electrical engineering R&D labs, concentrating on power electronics switches and their use. The first sections deal with key power electronics technologies, MOSFETs and IGBTs, including series and parallel associations. The next section examines silicon carbide and its potentiality for power electronics applications and its present limitations. Then, a dedicated section presents the capacitors, key passive components in power electronics, followed by a modeling method allowing the stray inductances computation, necessary for the precise simulation of switching waveforms. Thermal behavior associated with power switches follows, and the last part proposes some interesting prospectives associated to Power Electronics integration.

Synopsis Inter-Municipal Cooperation in Europe by : Rudie Hulst
This book presents an overview of inter-municipal cooperation in eight European countries. Each country study sketches its attendant forms, their institutional design, the tasks and competencies attributed to joint authorities of municipalities and the way inter-municipal cooperation operates in practice. Both performance and democratic aspects of cooperation are recurring topics.

Synopsis An Introduction to R for Spatial Analysis and Mapping by : Chris Brunsdon
"In an age of big data, data journalism and with a wealth of quantitative information around us, it is not enough for students to be taught only 100 year old statistical methods using ′out of the box′ software. They need to have 21st-century analytical skills too. This is an excellent and student-friendly text from two of the world leaders in the teaching and development of spatial analysis. It shows clearly why the open source software R is not just an alternative to commercial GIS, it may actually be the better choice for mapping, analysis and for replicable research. Providing practical tips as well as fully working code, this is a practical ′how to′ guide ideal for undergraduates as well as those using R for the first time. It will be required reading on my own courses." - Richard Harris, Professor of Quantitative Social Science, University of Bristol R is a powerful open source computing tool that supports geographical analysis and mapping for the many geography and ‘non-geography’ students and researchers interested in spatial analysis and mapping. This book provides an introduction to the use of R for spatial statistical analysis, geocomputation and the analysis of geographical information for researchers collecting and using data with location attached, largely through increased GPS functionality. Brunsdon and Comber take readers from ‘zero to hero’ in spatial analysis and mapping through functions they have developed and compiled into R packages. This enables practical R applications in GIS, spatial analyses, spatial statistics, mapping, and web-scraping. Each chapter includes: Example data and commands for exploring it Scripts and coding to exemplify specific functionality Advice for developing greater understanding - through functions such as locator(), View(), and alternative coding to achieve the same ends Self-contained exercises for students to work through Embedded code within the descriptive text. This is a definitive ′how to′ that takes students - of any discipline - from coding to actual applications and uses of R.
