Book Description
This title offers a comprehensive coverage of the many facets of seismic engineering. The first half of the book is devoted to seismic phenomena and hazards, detailing the causes of earthquakes, the parameters used to characterize earthquakes, strong ground motions, seismic hazards and their evaluation, and seismic action. The second half discusses the effects of earthquakes and tools used to assess and reduce risk, including the effects of vibratory motions and induced phenomena, seismic calculations and technical aspects of prevention. The importance of keeping orders of magnitude in mind (i.e. through reasoning or very simple equations) when discussing seismic phenomena and their effects is emphasized, a task which most people overlook because of their rarity and the brevity of their manifestations.

Book Description
L' interaction sol-structure en dynamique caractérisée usuellement par les fonctions d'impédance doit être prise en compte des la conception des ouvrages tant pour les fondations de machine que pour les fondations d'ouvrages soumis a l'action sismique. Les fonctions d'impédance relatives à une fondation, un type de sol, et un mode de vibration représentent, sous excitation harmonique, la raideur dynamique complexe du sol. Le travail de bibliographie regroupe l'ensemble des fonctions d'impédance relatives aux fondations superficielles trouvées dans la littérature sous forme paramétrée. Cette étude a permis la réalisation d'un ouvrage: manuel des fonctions d'impédance - fondations superficielles. Y apparaissent les résultats relatifs aux fondations de forme simple (circulaire, rectangulaire et filante) et aux sols de caractéristiques simples (milieu semi-infini, monocouche surmontant soit un substratum rigide, soit un demi-espace). Cet ouvrage permet au concepteur de prendre en compte l'interaction sol-structure dans les cas simples ou au niveau d'avant-projets. Une méthode pratique de prise en compte de l'interaction sol-fondation est développée dans le cas ou le sol peut être assimile a un monocouche homogène et viscoélastique reposant sur un substratum rocheux, et pour une fondation circulaire rigide. Les fonctions d'impédance des modes de translation horizontale et de balancement sont représentées par un modèle discret dont les paramètres, indépendants de la fréquence, sont déterminés par des abaques ou des formules empiriques en fonction de la géométrie sol-fondation du problème. Un amortisseur visqueux de caractéristiques dépendant hyperboliquement de la fréquence est utilise pour rendre compte des effets (en basses fréquences) de l'amortissement interne de la couche de sol. Le modèle fréquentiel ainsi réalise permet d'obtenir des réponses de structures en très bonne corrélation avec celles prenant en compte les fonctions complètes d'impédance

Book Description
This book has grown out of the research activities of the author in the fields of sound propagation in porous media and modelling of acoustic materials. It is assumed that the reader has a background of advanced calculus, including an introduction to differential equations, complex variables and matrix algebra. A prior exposure to theory of elasticity would be advantageous. Chapters 1-3 deal with sound propagation of plane waves in solids and fluids, and the topics of acoustic impedance and reflection coefficient are given a large emphasis. The topic of flow resistivity is presented in Chapter 2. Chapter 4 deals with sound propagation in porous materials having cylindrical pores. The topics of effective density, and of tortuosity, are presented. The thermal exchanges between the frame and the fluid, and the behaviour of the bulk modulus of the fluid, are described in this simple context. Chapter 5 is concerned with sound propagation in other porous materials, and the recent notions of characteristic dimensions, which describe thermal exchanges and the viscous forces at high frequencies, are introduced. In Chapter 6, the case of porous media having an elastic frame is considered in the context of Biot theory, where new topics described in Chapter 5 have been included.

Book Description
Sol-Gel processing methods, first used historically for decorative and constructional materials, were extensively developed in the last century for applications such as glasses, ceramics, catalysts, coatings, composites and fibres. Today they are reaching their full potential, enabling the preparation of new generations of advanced materials not easily accessible by other methods yet using mild, low-energy conditions. The topic is therefore increasingly included in advanced undergraduate, MSc and PhD programmes in the areas of chemistry, physics and materials science. This concise introductory text, written at the advanced undergraduate/first-year postgraduate level, is also suitable as an introduction to the development, mechanisms, chemistry, characterisation methods and applications of the technique. It provides readers with an extensive yet concise grounding in the theory of each area of the subject and details the real and potential applications and the future prospects of sol-gel chemistry.

Book Description
Sol-Gel Techniques for Glass Producers and Users provides technological information, descriptions and characterizations of prototypes, or products already on the market, and illustrates advantages and disadvantages of the sol-gel process in comparison to other methods. The first chapter entitled "Wet Chemical Technology" gives a summary of the basic principles of the sol-gel chemistry. The most promising applications are related to coatings. Chapter 2 describes the various "Wet Chemical Coating Technologies" from glass cleaning to many deposition and post-coating treatment techniques. These include patterning of coatings through direct or indirect techniques which have became very important and for which the sol-gel processing is particularly well adapted. Chapter 3 entitled "Bulk Glass Technologies" reports on the preparation of special glasses for different applications. Chapter 4 entitled "Coatings and Materials Properties" describes the properties of the different coatings and the sol-gel materials, fibers and powders. The chapter also includes a section dedicated to the characterization techniques especially applied to sol-gel coatings and products.
