Analysis of the Brinkman equation as a model for flow in porous media [PDF]
, 1987 The fundamental solution or Green's function for flow in porous media is determined using Stokesian dynamics, a molecular-dynamics-like simulation method capable of describing the motions and forces of hydrodynamically interacting particles in Stokes ...

Exact regularized point particle method for multi-phase flows in the two-way coupling regime [PDF]
, 2014 Particulate flows have been largely studied under the simplifying assumptions of one-way coupling regime where the disperse phase do not react-back on the carrier fluid.

Active noise control for periodic disturbances [PDF]
IEEE Transactions on Control Systems Technology, 1998 This paper proposes an active noise control algorithm for periodic disturbances of unknown frequency. The algorithm is appropriate for the feedback case in which a single error microphone is used. The previously-proposed algorithm (Bodson et al. (1997)) for the rejection of sinusoidal noise sources is extended for the cancellation of multiple harmonics.
