Book Description
L'ETUDE DES STRUCTURES FORMEES DE BARRES COMPOSITES EST COMPLIQUEE A CAUSE DES OSCILLATIONS DES COEFFICIENTS. L'OBJECTIF EST DE DONNER LE COMPORTEMENT ASYMPTOTIQUE DE CES STRUCTURES LORSQUE LES PETITS PARAMETRES LES CARACTERISANT TENDENT VES ZERO. DANS LA PREMIERE PARTIE, LES BARRES CONSIDEREES SONT NON SYMETRIQUES, LEUR ETUDE EST PLUS DIFFICILE. NOUS CONSTRUISONS UN DEVELOPPEMENT DE LA SOLUTION ET NOUS OBTENONS DES EQUATIONS HOMOGENEISEES UNIDIMENSIONNELLES DONT ON MONTRE LA POSITIVITE ET ON CALCULE NUMERIQUEMENT LES COEFFICIENTS. DES ESTIMATIONS D'ERREUR PERMETTENT LA JUSTIFICATION DE L'ASPECT ASYMPTOTIQUE DE L'APPROXIMATION. LA DEUXIEME PARTIE EST CONSACREE AU PROBLEME DE JONCTIONS DE BARRES DONT LES COEFFICIENTS NE SONT PAS DE LA MEME GRANDEUR. UN AUTRE PARAMETRE INTERVIENT DANS L'ETUDE ASYMPTOTIQUE. NOUS CONSTRUISONS UN DEVELOPPEMENT A L'INTERIEUR ET DES COUCHES LIMITES POUR CORRIGER LES CONDITIONS AUX BORDS.

Book Description
Preface Adhesion is a phenomenon architects and civil engineers are not very familiar with. In other disciplines knowledge about surface properties and the background of bonding energies is also far from satisfactory; nevertheless there are many important· applications in concrete engineering, where adhesion is necessary for success and durability. These include: - coating and painting - repair of concrete surfaces - bonding of fresh to old concrete - crack injection - glueing of precast elements - glueing of steel to concrete, etc. In 1981 RILEM established the technical committee 52-RAC 'Resin Adherence to Concrete'. The main aims of the committee's work were - to collect research results and practical experiences - to initiate and coordinate research programs - to develop, on a scientific base, test methods for field and for laboratory purposes. One of the results of the committee's work is a state-of-the-art report, which will be presented orally as a General Report at the International Symposium ISAP '86, and will be printed either in the RILEM journal Materials and Structures or separately. Several test recommendations have been elaborated and will be prepared as drafts for the participants ofISAP '86. These are: - direct tensile test - pull-off test - direct shear test - slant shear test - four-point bending test - dynamic loading test - thermal compatibility test (two versions) - injectibility test.

Book Description
This book deals with a wide class of novel and efficient adaptive signal processing techniques developed to restore signals from noisy and degraded observations. These signals include those acquired from still or video cameras, electron microscopes, radar, X-rays, or ultrasound devices, and are used for various purposes, including entertainment, medical, business, industrial, military, civil, security, and scientific. In many cases useful information and high quality must be extracted from the imaging. However, often raw signals are not directly suitable for this purpose and must be processed in some way. Such processing is called signal reconstruction. This book is devoted to a recent and original approach to signal reconstruction based on combining two independent ideas: local polynomial approximation and the intersection of confidence interval rule.
