Analysis of residual ripples and wheel-rail contact state after profiling milling for reshaping rail profile

Abstract On-line milling rail profile is a new technology developed in recent years, which eliminates serious defects such as wavy wear layer on the top surface of rail profile through profiling milling and reshapes the shape of rail profile. Previous studies have focused on the maximum milling thickness, milling efficiency and the ability to ...

Total monomeric anthocyanin concentration estimation of red wines based on color data using multivariate statistical analysis and machine learning

Journal of the Science of Food and Agriculture, EarlyView.
Abstract BACKGROUND Red wine is a high‐value grape derivative containing complex chemical compounds that dictate its quality. Qualitative and quantitative determination of these compounds is essential for standardizing and classifying the product. This proof‐of‐concept study integrates chemometric methods and machine learning algorithms to establish ...

Definition of composite profiles for the needs of a dynamic analysis of a rail vehicle

MATEC Web of Conferences, 2019
When modelling the dynamics of a rail vehicle ride, one of the important input parameters is the profile geometry of the wheel and rail treads. Commonly available simulation programs have databases containing some standardized profiles, or allow the ...

Gait Adaptability Training Improves Gait in Spinocerebellar Ataxia Patients

Movement Disorders Clinical Practice, EarlyView.
Abstract Background Spinocerebellar ataxia (SCA) is a rare, genetic neurodegenerative movement disorder primarily affecting the cerebellum. So far, there is no available cure for SCA. However, evidence suggests that neurorehabilitation can alleviate symptoms.
