Let Ω⊂ R 3 be an obstacle that is a simply connected bounded domain. The exterior Dirichlet
problem for the Helmholtz equation in R 3 \Ω with the Sommerfeld radiation condition at …

A time-dependent three-dimensional acoustic scattering problem is considered. An incoming
wave packet is scattered by a bounded, simply connected obstacle with locally Lipschitz …

A numerical algorithm for a three-dimensional inverse electromagnetic scattering problem is
considered. For time-harmonic waves the Maxwell's equations are reduced to the vector …

… by Colton and Monk in [11 and furtherdeveloped by Misici, Zirilli, and their coauthors in [12]-[15].
In particular, basedon previous work by Misici and Zirilli 14], we extend the Herglotz …

The use of the SIR model to predict the time evolution of an epidemic is very frequent and has
spatial information about its propagation which may be very useful to contrast its spread. In …

In this article, a lattice Boltzmann model for two immiscible fluids with same density but a
large viscosity difference is developed. The effect of surface tension is included. An indicator …

We consider the propagation of electromagnetic waves in an inhomogeneous medium. The
inhomogeneity is contained in a vertical cylinder with a compact base. When an incident …

We study the cooling system for submersible electric pumps. This study aims to provide some
guidelines to improve the existing cooling system of these electric pumps when they work …

From the knowledge of the anomalies of the gravitational field, we reconstruct the mass
density distribution in a large region of the state of Bahia (Brazil). This inverse gravimetry …
