SIAM Journal on Applied Mathematics, Vol. 67, No. 1 (2006), pp. 46-68 (23 pages) New quantum hydrodynamic equations are derived from a Wigner-Boltzmann model, using the quantum entropy minimization ...
Derivation of the dynamic correction to Grad’s moment system from kinetic equations (regularized Grad’s 13 moment system, or R13) is revisited. The R13 distribution function is found as a ...
Armed with even with the most-sophisticated motion controller, engineers can still find it difficult to attain precise linear motion unless the mechanical components are appropriately designed for the ...
