Euler-Lagrange coupling method is used to establish the fluid-structure interaction model for tires with different tread patterns by obtaining grounding mark and normal contact force between tire road surface during rolling. The altering of load force, pressure, water film thickness in relation effect on tire-road both constant speed critical hydroplaning was analyzed. Results show that are pos...

The article is devoted to demonstrating the possibilities of using 3D scanning technologies capture and study volumetric footprints. author notes that traditional methods visual fixation such reflections (description, measurement, photography) are not informative enough, main method object (making plaster other molds) associated with risk significant damage fixed trace. At same time, use contac...

This study tested the hypothesis that male athletes who feel pressured to maintain a specific body weight present an elevated risk of subclinical eating disorders. Twelve judoists (19.5 ± 0.5 yr), fifteen cyclists (21.2 ± 2.8 yr) and seventeen non- competitive students matched for BMI and used as controls (21.8 ± 1.8 yr) were studied using the Eating Attitudes Test (EAT-26). The Multidimensiona...
