Numerical Modelling of Boundary Layers and Far Field Acoustic Propagation in Thermoviscous Fluid
To model linear acoustics in a thermoviscous fluid in open domain and time-harmonic regime, a Finite Element formulation in a bounded meshed domain is combined with the integral representation of the field for the propagative soluti...

A versatile computational approach for the numerical modelling of parametric acoustic array
approximation. The primary acoustic field is calculated by the Rayleigh integral or the boundary element method; the secondary difference-frequency field is calculated by the finite element method. As governing wa...

Far field during sonication experiments in vitro-Is it really far enough?
In many in vitro experiments studying ultrasound bioeffects the sonicated samples are placed to far field with intention of exposing them to as uniform ultrasound field as possible. The main aim of this work is to assess wh...

Trace and norm of indecomposable integers in cubic orders
of totally real cubic fields. We prove that for cubic orders in these fields, the minimal traces of indecomposable integers multiplied by totally positive elements of the codifferent can be arbitrarily large. This is very ...
