Hybrid experimental-numerical characterization of the effect of strain rate on fracture includes notched as well as uniaxial tension specimens. Local displacements and surface strain fields are measured optically in all experiments using Digital Image Correlation. Constitutive equations derived from the...
Types of input data We have benefited of several types of data in order to obtain the thermal emission of a variety Earth-like planets. First, we have used high-resolution thermal emission data of the Earth (Section 3.1), the data are...
Revue de littérature L’étude des problématiques concernant la rivière a été réalisée dans le premier cha- pitre. On a ainsi montré que la gestion de la rivière comprenait un nombre croissant de contraintes, notamment les contraintes de conservation voire de...
Mondrian Random forests: theory and methodology Introduction Introduced by Breiman (2001a), Random Forests (RF) are state-of-the-art classification and regression algorithms that proceed by averaging the forecasts of a number of randomized decision trees grown in parallel. Many extensions of RF...
Contrôlabilité simultanée de deux et trois équations Structure of the article This article is organized as follows. We recall, in Section 3.2, well posedness results. To emphasize the ideas developed in this article, we start by proving Theorem 3.5. Section...
An improper estimator with optimal excess risk in misspecified density estimation and logistic regression Abstract. We introduce a procedure for predictive conditional density estimation under logarithmic loss, which we call SMP (Sample Minmax Predictor). This estimator minimizes a new general...
Aggregated Mondrian forests for online learning Introduction Introduced by Breiman (2001a), Random Forests (RF) is one of the algorithms of choice in many supervised learning applications. The appeal of these methods comes from their remarkable accuracy in a variety of...
Dynamique intrinsèque de l'écosystème et rôle de mélange vertical Introduction Le but de cette première partie est tout d’abord d’étudier la dynamique d’un modèle d’écosystème très simplifié avec deux espèces de phytoplancton. Nous verrons, après une description détaillée des caractéristiques...
HARBOR RESONANCES IN COASTAL ENGINEERING In this chapter we consider the application of the half-plane Helmholtz problem described in Chapter III to the computation of harbor resonances in coastal engineering. We consider the problem of computing resonances for the Helmholtz...
Les ordinateurs et les autres appareils électroniques sont de plus en plus présents dans notre vie quotidienne. Améliorer la qualité des interactions homme–machine et des communications a travers d’une machine devient donc, un sujet de recherche très pertinent et très...
