DOI: 10.1016/j.mechmachtheory.2020.104057
Abstract: Abstract The planar ball reducer is small in size and is simple in processing. However, the relative velocity between the wave generator and ball is large, which decreases the operation efficiency. In this work, a… read more here.

DOI: 10.3390/math9162001
Abstract: This paper presents a generalized second-order hydrodynamic traffic model. Its central piece is the expression for the relative velocity of the congestion (compression wave) propagation. We show that the well-known second-order models of Payne–Whitham, Aw–Rascal… read more here.
