In polygynous mammals, mating success of males often depends on intense male-male competition and the use of alternative mating tactics. Because reproduction incurs substantial energetic costs and risks of fight injuries, mate selection by males should be expected, particularly when females vary in their ability to produce offspring but can only be defended 1 at a time. Here, we investigated during 3 ruts how age and social rank of male mountain goats (Oreamnos americanus) affected the format...
Plusieurs poutres de géométrie et de matériaux différents sont amenées à la rupture pour observer leur comportement à la flexion et à l’effort tranchant. Cette observation est faite par l’intermédiaire d’essais en laboratoire et de simulations numériques 3D non linéaires, accompagnée de conseils judicieux pour l’utilisation des matériaux en polymère renforcés de fibres de carbone (PRFC) et des bétons renforcés de fibres (BRF). De plus, ces matériaux sont exploités à leur maximum en les c...
In this paper, we propose and assess the accuracy of new fuel consumption estimation models for vehicle routing. Based on real-world data consisting of instantaneous fuel consumption, time-varying speeds observations, and high-frequency traffic, we propose effective methods to estimate fuel consumption. By carrying out nonlinear regression analysis using supervised learning methods, namely Neural Networks, Support Vector Machines, Conditional Inference Trees, and Gradient Boosting Machines, w...
