An Hybrid Evolutive-Genetic Strategy for the Inverse Fractal Problem of IFS Models
Iterated Function Systems are popular techniques for gene- rating selfsimilar fractals. An important practical problem in this field is that of obtaining the IFS code which approximates a given image with a ce...

Newton’s Method under Different Lipschitz Conditions
The classical Kantorovich theorem for Newton’s method assumes that the derivative of the involved operator satisfies a Lipschitz condition ∥;F’(x 0)-1 [F’(x) -’’(y)] ∥≤ L∥x - y∥ In this co...

Phase Planning for Overall Copper-Fiber Switch-over
This paper introduces a phase planning concept to the imminent copper-fiber switch-over action. Traditional copper loops are to be replaced by modern fiber lines in order to keep up with the current evolution ...

Open AccessIntegrated “omics” profiling indicates that miRNAs are modulators of the ontogenetic venom composition shift in the Central American rattlesnake, Crotalus simus simus
Understanding the processes that drive the evolution of snake venom is a topic of great research interest in molecular and evolutionary toxinology. Recent studies suggest that ontogenetic changes in venom comp...

Frozen Iterative Methods Using Divided Differences “à la Schmidt–Schwetlick”
The main goal of this paper is to study the order of convergence and the efficiency of four families of iterative methods using frozen divided differences. The first two families correspond to a generalization...

Influence of the multiplicity of the roots on the basins of attraction of Newton’s method
In this work, we develop and implement two algorithms for plotting and computing the measure of the basins of attraction of rational maps defined on the Riemann sphere. These algorithms are based on the subdiv...

A multidimensional generalization of some classes of iterative methods
In this paper we extend to the multidimensional case some iterative methods that are known in their scalar version. All the schemes considered here are two-step methods with fourth-order local convergence, whe...

Towards process-informed bias correction of climate change simulations
Biases in climate model simulations introduce biases in subsequent impact simulations. Therefore, bias correction methods are operationally used to post-process regional climate projections. However, many prob...
