Physicist Richard Lieu first theorized that gravity could exist without mass—now he’s got a new cosmological model that eschews the need for dark energy.

The steady state and dynamic models discussed herein include a comprehensive, unlimited maneuver tire model with relatively simple vehicle suspension kinematics and inertial dynamics to cover the full ...

The steady-state flow is examined for a car-following model in which the acceleration at time t of a car attempting to follow a lead car is proportional to the relative velocity at a time t-Δ and in ...
