A novel method to derive wheel / rail wear coefficient in the field using multi-body dynamics

open access: yesNihon Kikai Gakkai ronbunshu, 2021
To predict the wheel/rail profile wear theoretically with dynamic model of the vehicle-track systems, the wear coefficient is necessary and these parameters are generally derived from laboratory tests, such as twin disk test or a pin-on-disk test ...

Plastic Plants: The Role of Water Hyacinths in Plastic Transport in Tropical Rivers

open access: yesFrontiers in Environmental Science, 2021
Recent studies suggest that water hyacinths can influence the transport of macroplastics in freshwater ecosystems at tropical latitudes. Forming large patches of several meters at the water surface, water hyacinths can entrain and aggregate large amounts
