Reliable approximation of separatrix manifolds in competition models with safety niches
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 situation is rather common especially in populat…
Computing Topology Preservation of RBF Transformations for Landmark-Based Image Registration
R. Cavoretto, A. De Rossi, H. Qiao +3
In image registration, a proper transformation should be topology preserving. Especially for landmark-based image registration, if the displacement of one landmark is larger enough…
Partition of Unity Interpolation on Multivariate Convex Domains
Roberto Cavoretto, Alessandra De Rossi, Emma Perracchione
In this paper we present a new algorithm for multivariate interpolation of scattered data sets lying in convex domains $Ω\subseteq \RR^N$, for any . To organize the point…
A trivariate interpolation algorithm using a cube-partition searching procedure
Roberto Cavoretto, Alessandra De Rossi
In this paper we propose a fast algorithm for trivariate interpolation, which is based on the partition of unity method for constructing a global interpolant by blending local radi…
Two-dimensional interpolation using a cell-based searching procedure
Roberto Cavoretto
In this paper we present an efficient algorithm for bivariate interpolation, which is based on the use of the partition of unity method for constructing a global interpolant. It is…
Graphical representation of separatrices of attraction basins in two and three dimensional dynamical systems
Roberto Cavoretto, Alessandra De Rossi, Emma Perracchione +1
In this paper we consider the problem of reconstructing separatrices in dynamical systems. In particular, here we aim at partitioning the domain approximating the boundaries of the…
Local interpolation schemes for landmark-based image registration: a comparison
Giampietro Allasia, Roberto Cavoretto, Alessandra De Rossi
In this paper we focus, from a mathematical point of view, on properties and performances of some local interpolation schemes for landmark-based image registration. Precisely, we c…
A two-strain ecoepidemic competition model
Roberto Cavoretto, Simona Collino, Bianca Giardino +1
In this paper we consider a competition system in which two diseases spread by contact. We characterize the system behavior, establishing that only some configurations are possible…
On the principle of competitive exclusion in metapopulation models
Davide Belocchio, Roberto Cavoretto, Giacomo Gimmelli +2
In this paper we present and analyse a simple two populations model with migrations among two different environments. The populations interact by competing for resources. Equilibri…
Comparing disease control policies for interacting wild populations
Iulia Martina Bulai, Roberto Cavoretto, Bruna Chialva +2
We consider interacting population systems of predator-prey type, presenting four models of control strategies for epidemics among the prey. In particular to contain the transmissi…
