Conservation of energy between the times of impacts (since there is no non-conservative work being done between impacts). Conservation of linear momentum in the x-direction for ALL time (since no net ...

Based on the conservation of linear momentum, negative force can be generated without restrictions on the beam's shape, polarization, phase and so on.

In this paper, fully discrete entropy conditions of a class of high resolution schemes with the MmB property are discussed by using the theory of proper discrete entropy flux for the linear scalar ...
