High speed trains are an indispensable part of rapid transportation systems in many countries. As the fastest means of transport on the ground, these trains are extremely sensitive to the terrain and track conditions. Geometrical irregularities and mechanical characteristics of the track, together with inconsistencies in the lane (including bridges that support the track) are considered importa...

The behaviour of a non-spherical osmotic motor an axisymmetric catalytic particle self-propelling in a dilute dispersion of reactant particles is considered. In concrast to a conventional osmotic motor that creates differences in concentration, and hence in osmotic pressure, due to asymmetry in reaction rate along its surface (e.g. a Janus particle with reactive and non-reactive patches), a non...

Abstract Sailing navigation is an activity that requires acquiring and processing information from the surrounding environment. The advancement of technology has enabled sailboats to have increasing number onboard sensors make sailing more user-friendly. However, data provided by these are still visualized on 2D digital displays imitate traditional analog interfaces. Although strategically plac...

Introduction. Sailing is a sport that places high demands on the physical fitness of an athlete. Despite fact this has been practiced for very long time, experts have not paid due attention to assessing impact athlete’s load during training his fatigue. The use mathematical modeling methods at stage athletes select optimal will make more effective. In order determine method, which allow quite s...
