Abstract The hunting phenomenon is an intrinsic swaying motion appearing in railway vehicles due to the vehicle’s forward speed and wheel–rail contact forces. Hunting consists of wheelset other components oscillations that arise above a certain known as critical or speed. These are unstable nature represent safety hazard they could lead derailment. This article analyses stability bogie nonlinea...

Embedded turnout is one of the key facilities in embedded track network modern tram systems. In this study, damping performance and stiffness an are tested on site. A multi-rigid body dynamics model a finite-element established, two models coupled based wheel-rail contact theory for area. Next, dynamic responses passing through analyzed. The results show that has favorable performance. high var...

Oral white lesions are quite common clinical conditions in dental practice. They can be an expression of different diseases, so it is crucial to achieve a correct diagnosis start adequate treatment. However, differential not always easy because the appearance oral often similar and non-pathognomonic. We report on 42-year-old Caucasian woman who complained chronic patch left border her tongue. A...

Abstract This paper develops a wheel profile fine-tuning system (WPFTS) that comprehensively considers the influence of on damage, vehicle stability, safety, and passenger comfort. WPFTS can recommend one or more optimized profiles according to train operators’ needs, e.g., reducing wear, mitigating development out-of-roundness (OOR), improving shape stability profile. Specifically, includes fo...

For years, formal methods have been successfully applied in the railway domain to formally demonstrate safety of systems. Despite that, little has done field address cyber-physical nature modern signalling In this article, we present an approach for a development systems that is based on refinement-based modelling and proof-based verification. Our utilises Event-B specification language togethe...

Sport management programs are essential pathways by which aspiring professionals in the sport industry achieve their university education. Although a substantial segment of scholarship has focused on driving for higher rates diversity, equity, and inclusion industry, less attention been paid to academy. In this study, we examine gender representation full-time faculty positions, publications, r...

High-speed trains serving in a crosswind region are bearing more significant safety risks. Based on the three-dimensional (3D) Unsteady Reynolds-Averaged Navier–Stokes (URANS) turbulence model, Computational Fluid Dynamics (CFD) computational work was conducted present study to predict transient aerodynamic load of train. The then employed as input dynamic system perform analysis running safety...
