ANALYSIS ON RUNNING SAFETY CONSIDERING THE DIFFERENCE OF COEFFICIENTS OF FRICTION IN A RAILWAY BOGIE (COMPARISON BETWEEN EXPERIMENT AND NUMERICAL SIMULATION OF THE ROLLER-RIG TEST)

It is important to secure running safety of railway vehicles against wheel-climb derailment accidents.The safety is often discussed according to the value of derailment coefficients for the leading outside wheel of a railway bogie running on sharp curves.Therefore, the detailed force induced mechanism which influences the value of derailment coeffi

Machine learning methods have gained widespread utilization in small and micro enterprise credit risk assessment.However, the practical application of these methods encounters a conundrum involving accuracy and interpretability.In Wooden Toy this study, a multi-stage ensemble model is proposed to enhance the model’s interpretability.To stren

An incompressible two-dimensional laminar flow of micropolar fluid subjected to a stretched surface is examined.The steady-state thermally radiative flow experiences the influence of melting phenomenon.The dimensionalized flow model for axi-symmetric flow is governed through similarity variables.Runge-Kutta-Fehlberg (RKF-45) method is applied to th

The article presents a method for segmentation of ethnomusicological field recordings.Field recordings are integral documents of folk music performances captured in the field, and typically contain performances, intertwined with interviews and commentaries.As these are live recordings, captured in non-ideal conditions, they usually contain signific

In this article all the effective parameters in response of nonlinear passive viscous systems are investigated.Here, the term response is referred to the maximum inter-story drift and maximum absolute acceleration of the stories.Inter-story drift is known as the structural failure index and maximum absolute acceleration is known as the nonstructura
