An RBF-PSO Based Approach for Modeling Prostate Cancer
Emma Perracchione, Ilaria Stura
Prostate cancer is one of the most common cancers in men. It is characterized by a slow growth and it can be diagnosed in an early stage by observing the Prostate Specific Antigen…
Wild herbivores in forests: four case studies
Giorgio Sabetta, Emma Perracchione, Ezio Venturino
A three population system with a top predator population, i.e. the herbivores, and two prey populations, grass and trees, is considered to model the interaction of herbivores with…
Approximating basins of attraction for dynamical systems via stable radial bases
Roberto Cavoretto, Stefano De Marchi, Alessandra De Rossi +2
In applied sciences, such as physics and biology, it is often required to model the evolution of populations via dynamical systems. In this paper, we focus on the problem of approx…
Fast and flexible interpolation via PUM with applications in population dynamics
Alessandra De Rossi, Roberto Cavoretto, Emma Perracchione
In this paper the Partition of Unity Method (PUM) is efficiently performed using Radial Basis Functions (RBFs) as local approximants. In particular, we present a new space-partitio…
Robust approximation algorithms for the detection of attraction basins in dynamical systems
Roberto Cavoretto, Alessandra De Rossi, Emma Perracchione +1
In dynamical systems saddle points partition the domain into basins of attractions of the remaining locally stable equilibria. This problem is rather common especially in populatio…
