In this paper, the Partition of Unity (PU) method is performed by blending Radial Basis Functions (RBFs) as local approximants and using locally supported weights. In particular, we present a new multidimensional data structure which makes use of an integer-based scheme. This approach allows to perform an optimized space-partitioning structure. Moreover,(More)
In a mathematical model involving a set of ordinary differential equations, a particular solution of the system is completely determined by the initial condition. When the omega limit set reduces to a point, the solution settles at steady state. The possible steady states of the system are completely determined by its parameters. However, it is possible(More)
Mathematical modelling is being applied in major disciplines, such as biology, medicine and social sciences and the aim of such models lies in the prediction of the temporal evolution of the considered quantities. The possible steady states of the system are completely determined by its parameters. However, it is possible that more steady states can(More)
