The day-to-day practice of designing/reorganizing traffic management at a controlled intersection typically relies on the use of a traffic demand model. The selection of such a model is usually guided by considerations of the optimal balance between the complexity of the model and the significance of the effects that can be accounted for. However, in some situations, researchers ...

Torsional vibrations are observed in all mechanisms that involve rotational movement of shafts. For internal combustion engines, the problem of torsional vibrations of the crankshaft is relevant, since significant vibrations prevent its fatigue failure. In addition, torsional vibrations negatively affect engine performance, efficient fuel consumption, oil and sugar consumption, ...
