Lattice Boltzmann phase-field modelling of binary-alloy solidification

Some Remarks about the Hilbert Transform

In this paper we present som eremarks about the Hilbert transform on the real line and its numerical approximation, in connection with its application in signal processing.

On the condensed density of the generalized eigenvalues of pencils of Gaussian random matrices and applications

Pencils of matrices whose elements have a joint noncentral Gaussian distribution with nonidentical covariance are considered. An approximation to the distribution of the squared modulus of their determinant is computed which allows to get a closed form approximation of the condensed density of the…

A numerical method for the generalized airfoil equation based on the de la Vallée Poussin interpolation

The authors consider the generalized airfoil equation in some weighted Holder-Zygmund spaces with uniform norms. Using a projection method based on the de la Vallée Poussin interpolation, they reproduce the estimates of the L2 case by cutting off the typical extra log m factor which seemed…

Near-critical reflection of internal waves

Internal waves describe the (linear) response of an incompressible sta- bly stratified fluid to small perturbations. The inclination of their group velocity with respect to the vertical is completely determined by their frequency. Therefore the reflection on a sloping boundary cannot follow…

IAC (1927-2012): 85 years in computational and applied mathematics

Breve storia dell'Istituto per le Applicazioni del Calcolo "Mauro Picone". Nel 2012, cadono diverse ricorrenze: l'85° anniversario della sua fondazione; l'80° anniversario dall'inserimento nel CNR, di cui fu il primo istituto; il 50° anniversario del primo concreto progetto per la costruzione di un…

Surface Roughness-Hydrophobicity Coupling in Microchannel and Nanochannel Flows

An approach based on a lattice version of the Boltzmann kinetic equation for describing multiphase flows in nano- and microcorrugated devices is proposed. We specialize it to describe the wetting-dewetting transition of fluids in the presence of nanoscopic grooves etched on the boundaries. This…

Penetration of the blood-brain barrier and the anti-tumour effect of a novel PLGA-lysoGM1/DOX micelle drug delivery system

Effective treatment of glioma and other central nervous system (CNS) diseases is hindered by the presence of the blood-brain barrier (BBB). A novel nano-delivery vehicle system composed of PLGA-lysoGM1/DOX micelles was developed to cross the BBB for CNS treatment. We have shown that doxorubicin (…
