Available in PDF, EPUB and Kindle. Book excerpt: L'objectif de ce travail est d'une part de décrire les mécanismes fondamentaux intervenants en optique de champ proche, et d'autre part de développer des concepts permettant l'interprétation quantitative des images. Les points étudiés sont le concept de sonde passive, le couplage entre les contrastes d'indice et la topographie, les effets de polarisation, le problème inverse, l'influence de la cohérence, le phénomène de speckle en champ proche, la comparaison entre les différents modes de balayge et la réciprocité entre les modes collection et illumination.

This book was released on 2004 with total page 169 pages. Available in PDF, EPUB and Kindle. Book excerpt: This work consists in the development of a theoretical tool for the purpose to undertake numerical simulations able to take into account the coupling between the probe and the object. The first part, concerns the combination of the differential method and the algorithms T and S, to overcome numerical problems which appear in the cases where the size of system (probe - object) is more realistic. The developed global model is two-dimensional and applied in polarization TE under the normal diffraction condition. We have used the developed model to study the formation of optical image by monomodes and multimodes probes. The obtained optical images at constant height, have allowed us to study the installation of guided modes, and then to study the influence of the apex shape and size. By calculating the transfer functions in the case of monomodes probes we have observed that this function of transfer can exist only in particular cases ( e.g. of size of objects, distance probe-object, incidence angle etc) and that in general a pseudo-function of transfer remains accessible. To validate our results, we have studied more complicated (structured) probes, possessing a core, a sheath and possibly a metallic coating. With a very good qualitative agreement with experimental results recorded at constant intensity mode, it is interesting to observe that the attacked probe is more efficient than the etched probe. By extending our study to the infrared near-field, the study of spectroscopy map about the detection of an absorbent object embedded in a dielectric layer confirms the former results : the probe modify slightly the spectroscopic signature. This application shows the pertinence of the theoretical model and its large applications in any spectral domain.

Available in PDF, EPUB and Kindle. Book excerpt: Ce livre présente l'éat de l'art de l'ensemble des connaissances sur le champ proche optique. Ecrit par les meilleurs spécialistes de ce nouveau domaine de la physique, il couvre avec la même rigueur aussi bien les nouvelles modélisations des champs électromagnétiques que les tous derniers exemples d'application. Comme de nombreux domaines de recherche en émergence, le champ proche optique nécessitera encore de gros efforts tant théoriques qu'expérimentaux. Mais l'abondance des données accumulées par les auteurs de ce livre en fait une base précieuse pour les utilisateurs présents et futurs du champ proche optique, dans des domaines aussi variés que la microbiologie, les nanotechnologies, la nanoconnectique, les objets communicants, les télécommunications optiques... Un des objectifs réussi de ce livre est de fournir aux lecteurs avertis ou non, les connaissances nécessaires pour accéder à ces nouveaux domaines applicatifs encore si peu explorés.

Available in PDF, EPUB and Kindle. Book excerpt: Cet ouvrage illustre de façon claire et pédagogique les méthodes et les concepts qui sont à la base des progrès de la génomique en biologie végétale (grands programmes internationaux de séquençage, outils de la bio-informatique, méthodes d'analyse de l'expression des gènes incluant leurs produits métaboliques finaux et leur spécificité tissulaire et/ou cellulaire). Il rend compte des applications potentielles de la génomique dans les domaines de la génétique et de l'amélioration des plantes, de l'écophysiologie et de l'agronomie. Ce livre s'adresse aux étudiants de fin d'études universitaires ou agronomiques, aux professeurs de l'enseignement supérieur, aux techniciens, aux ingénieurs et scientifiques qui souhaitent acquérir des connaissances en génomique végétale.

Available in PDF, EPUB and Kindle. Book excerpt: For a meaningful understanding of physics, it is necessary to realise that this corpus of knowledge operates in a register different from natural thought. This book aims at situating the main trends of common reasoning in physics with respect to some essential aspects of accepted theory. It analyses a great many research results based on studies of pupils and students at various academic levels, involving a range of physical situations. It shows the impressive generality of the trends of common thought, as well as their resistance to teaching. The book's main focus is to underline to what extent natural thought is organised. As a result of this mapping out of trends of reasoning, some suggestions for teaching are presented; these have already influenced recent curricula in France. This book is intended for teachers and teacher trainers principally, but students can also benefit from it to improve their understanding of physics and of their own ways of reasoning.
Download or read book Expanding the Lexicon written by Sabine Arndt-Lappe and published by Walter de Gruyter GmbH & Co KG. This book was released on 2018-01-22 with total page 282 pages. Available in PDF, EPUB and Kindle. Book excerpt: The creation of new lexical units and patterns has been studied in different research frameworks, focusing on either system-internal or system-external aspects, from which no comprehensive view has emerged. The volume aims to fill this gap by studying dynamic processes in the lexicon – understood in a wide sense as not being necessarily limited to the word level – by bringing together approaches directed to morphological productivity as well as approaches analyzing general types of lexical innovation and the role of discourse-related factors. The papers deal with ongoing changes as well as with historical processes of change in different languages and reflect on patterns and specific subtypes of lexical innovation as well as on their external conditions and the speakers’ motivations for innovating. Moreover, the diffusion and conventionalization of innovations will be addressed. In this way, the volume contributes to understanding the complex interplay of structural, cognitive and functional factors in the lexicon as a highly dynamic domain.

Download or read book Optical Measurement of Surface Topography written by Richard Leach and published by Springer Science & Business Media. This book was released on 2011-03-31 with total page 333 pages. Available in PDF, EPUB and Kindle. Book excerpt: The measurement and characterisation of surface topography is crucial to modern manufacturing industry. The control of areal surface structure allows a manufacturer to radically alter the functionality of a part. Examples include structuring to effect fluidics, optics, tribology, aerodynamics and biology. To control such manufacturing methods requires measurement strategies. There is now a large range of new optical techniques on the market, or being developed in academia, that can measure areal surface topography. Each method has its strong points and limitations. The book starts with introductory chapters on optical instruments, their common language, generic features and limitations, and their calibration. Each type of modern optical instrument is described (in a common format) by an expert in the field. The book is intended for both industrial and academic scientists and engineers, and will be useful for undergraduate and postgraduate studies.
