Degradation of Ion–Plasma Nitride Coatings at Different Scale Levels under Frictional Wear Conditions

Abstract In tribological tests of coatings, cyclic loads enable to evaluate the relationships between their wear, the kinetics of the initiation and propagation of cracks, as well as fatigue failure. For such purposes, a concept of degradation at different scale levels was develo...

ASSESSMENT OF BRAKING PERFORMANCE OF NON-AUTONOMOUS MOTOR-CAR ROLLING STOCK BASED ON THE METHOD OF ACCOUNTING FOR DESIGN PERFORMANCE OF BRAKING MECHANISMS

The study objective is to develop a method for assessing the design perfection of a braking mechanism as the basis for assessing the braking efficiency of non autonomous motor-car rolling stock. To implement this method, the maximum deviation of the average values of the normal f...

Projected region-of-attraction analysis of coupled two-region low-altitude air traffic using microsimulation-calibrated MFDs

Low-altitude air traffic (LAAT) management requires macroscopic models that represent interactions between regional demand and service allocation. This study develops a projected stability-analysis framework for a two-region macroscopic fundamental diagram (MFD) model with intra-...
