On the convergence of an optimal fourth-order family of methods and its dynamics
(Applied Mathematics and Computation, 2015-02)
In this paper, we present the study of the semilocal and local convergence of an optimal fourth-order family of methods. Moreover, the dynamical behavior of this family of iterative methods applied to quadratic polynomials ...
A4Learning : Un enfoque metodológico iterativo para apoyar mejor el aprendizaje y la enseñanza
(IEEE Latin America Transactions, 2015-02)
Usability has been identified as one of the top unsolved challenges to improve a visual presentation of any type of information. The design and implementation of a visualization tool should incorporate usability by design, ...
On the election of the damped parameter of a two-step relaxed Newton-type method
(Nonlineard Dynamics, 2016-04)
In this paper, we are interested to justified two typical hypotheses that appear in the convergence analysis, |λ|≤2|λ|≤2 and z0z0 sufficient close to z∗z∗ . In order to proof these ideas, the dynamics of a damped ...
Local convergence and the dynamics of a two-point four parameter Jarratt-like method under weak conditions
(Numerical Algorithms, 2017-02)
We present a local convergence analysis of a two-point four parameter Jarratt-like method of high convergence order in order to approximate a locally unique solution of a nonlinear equation. In contrast to earlier studies ...

Educating at Scale for Sustainable Development and Social Enterprise Growth: The Impact of Online Learning and a Massive Open Online Course (MOOC)
(Sustainability, 2020-04)
The solutions to the grand challenges of sustainability, poverty, and health affecting the world will require education and capacity building for all individuals implementing change on a global scale. The challenge ahead ...
Multifractal images of the seismicity in the Ibero-Maghrebian region (westernmost boundary between the Eurasian and African plates)
(Tectonophysics, 2014-07)
The earthquake occurrence has a scale-invariant behavior that can be analyzed by means of a set of non-integer dimensions. The capacity dimension is related to the number of spatially distributed earthquakes, that is, to ...
Los clubs de suscriptores como nuevo modelo de financiación de la prensa generalista
(El profesional de la Información, 2016-05)
Hasta el año 2014, y al margen de algunas experiencias poco exitosas, no se apreciaba una corriente muy favorable a la
instalación de un pay wall en los grandes diarios españoles. Pero sería a partir de ese mismo año ...
Adaptive attunement of selective covert attention to evolutionary-relevant emotional visual scenes
(Consciousness and Cognition, 2017-05)
We investigated selective attention to emotional scenes in peripheral vision, as a function of adaptive relevance of scene affective content for male and female observers. Pairs of emotional neutral images appeared ...
On the convergence of inexact two-point Newton-like methods on Banach spaces
(Applied Mathematics and Computation, 2015-08)
We present a unified convergence analysis of Inexact Newton like methods in order to approximate a locally unique solution of a nonlinear operator equation containing a nondifferentiable term in a Banach space setting. The ...
