This paper presents a modification to the AffineProjection-Like I Algorithm for adaptive filtering withthe purpose of reducing the number of updates and sothe computational load. The modification is achievedby codifying the error and setting a threshold in orderthat the adaptive filter does not need to calculate thealgorithm every iteration. Simulation results showsame convergence speed than the Affine...
This paper presents the performance of algorithm Vortex Particle Swarm Optimization (VPSO) using the well-known 2D test functions. The algorithm VPSO mimics living organism strategies such as foraging and predator avoidance. In this way, VPSO employ vorticity features in order to escape from local minima. The swarm convergence is given by translational movements and the exploration by a dispersion...
In this work we study the global dynamics of the tumorangiogenesis developed by Louise Viger using the Localizationof Compact Invariant Sets. This model describes thebehavior and interactions of the population of host, effector, tumor and endothelial cells. We defined the upper andlower bounds for the cell populations. These bounds containall dynamics of the state variables for any initial conditionalso...
