Nondestructive evaluation of spatially varying internal heat transfer coefficients in a tube

We derive a rule for the reconstruction of the internal heat transfer coefficient hint of a pipe, from temperature maps collected on the external face. The pipe is subjected to internal heating by connecting two electrodes to the external surface. To estimate hint we apply the perturbation theory…

Density estimation of functionals of spatial point processes with application to wireless networks

Convergence of diffusive BGK approximations for nonlinear strongly parabolic systems

Estimate of traffic emissions through multiscale second order models with heterogeneous data

In this paper we propose a multiscale traffic model, based on the family of Generic Second Order Models, which integrates multiple trajectory data into the velocity function. This combination of a second order macroscopic model with microscopic information allows us to reproduce significant…

On the role of specific drug binding in modelling arterial eluting stents

In this paper we consider drug binding in the arterialwall following delivery by a drug-eluting stent. Whilst it is now generally accepted that a non-linear saturable reversible binding model is required to properly describe the binding process, the precise form of the binding model varies between…

Area-preserving curve-shortening flows: from phase separation to image processing

Are the Effects of Large Scale Flow Conditions Really Lost Through the Turbulent Cascade?

The conceptual framework for modeling the inertial subrange is strongly influenced by the Kolmogorov cascade phenomena, which is now the subject of significant reinterpretation. It has been argued that the effects of boundary conditions influence large-scale motion and direct interaction between…

Static and dynamic Melvin universes

We briefly review the known properties of Melvin's magnetic universe and study the propagation of test charged matter waves in this static spacetime. Moreover, the possible correspondence between the wave perturbations on the background Melvin universe and the motion of charged test particles is…

Weighted L1 approximation on [-1,1] via discrete de la Vallée Poussin means

We consider some discrete approximation polynomials, namely discrete de la Vallée Poussin means, which have been recently deduced from certain delayed arithmetic means of the Fourier-Jacobi partial sums, in order to get a near-best approximation in suitable spaces of continuous functions equipped…

Moser type estimates in nonlinear Neumann problems

Sharp exponential estimates for solutions to homogeneous Neumann problems for nonlinear elliptic equations in open subsets ! of Rn are established, with data from limiting Lebesgue spaces, or, more generally, Lorentz spaces.
