This study presents an analysis of the dynamics of a single and multiple chains of spherical super-paramagnetic beads suspended in a Newtonian fluid under the combined effect of an external rotating magnetic field and a ... -
Efficient Rotating Frame Simulation in Turbomachinery
(2014-12-31)This paper deals with the simulation of steady flows in tur- bomachinery. Two approaches are proposed, the first one is the classical multiple-rotating frame method (MRF) by multi- zone approach where the different zones ... -
Group-level progressive alterations in brain connectivity patterns revealed by diffusion-tensor brain networks across severity stages in Alzheimer's disease
Rasero, J.; Alonso-Montes, C.; Diez, I.; Olabarrieta-Landa, L.; Remaki, L.; Escudero, I.; Mateos, B.; Bonifazi, P.; Fernandez, M.; Arango-Lasprilla; Stramaglia, S.; Cortes, J.M. (2017-07-01)
Alzheimer’s disease (AD) is a chronically progressive neurodegenerative disease highly correlated to aging. Whether AD originates by targeting a localized brain area and propagates to the rest of the brain across ... -
High order discontinuous finite-volume/finite-element method for CFD applications
(2014-12-31)The proposed method naturally merges the desirable conservative properties and intuitive physical formulation of the widely used finite-volume (FV) technique, with the capability of local arbitrary high-order accuracy and ... -
High-order mixed weighted compact and non-compact scheme for shock and small length scale interaction
(2013-12-31)It is critical for a numerical scheme to obtain numerical results as accurate as possible with limited computational resources. Turbulent processes are very sensitive to numerical dissipation, which may dissipate the small ... -
