A variant of Steffensen-King's type family with accelerated sixth-order convergence and high efficiency index: Dynamic study and approach
(Applied Mathematics and Computation, 2015-02)
First, it is attempted to derive an optimal derivative-free Steffensen-King's type family without memory for computing a simple zero of a nonlinear function with efficiency index 4(1/3) approximate to 1.587. Next, since ...
Cognitive reserve is associated with the functional organization of the brain in healthy aging: a MEG study
(Frontiers in Aging Neuroscience, 2014-06)
The proportion of elderly people in the population has increased rapidly in the last century and consequently "healthy aging" is expected to become a critical area of research in neuroscience. Evidence reveals how healthy ...
Stability study of eighth-order iterative methods for solving nonlinear equations
(Journal of Computational and Applied Mathematics, 2016-01)
In this paper, we study the stability of the rational function associated to a known family of eighth-order iterative schemes on quadratic polynomials. The asymptotic behavior of the fixed points corresponding to the ...
EPIBI: Escala de Percepción de Indicadores de Bienestar Infantil. Validación del instrumento utilizando modelos politómicos de Rasch
(Revista de Educación, 2014-04)
La obtención de indicadores para el análisis las condiciones de vida de los niños es una preocupación creciente en nuestra sociedad. Prueba de ello es que diversos organismos e instituciones nacionales e internacionales ...
Improving supervised learning classification methods using multi-granular linguistic modelling and fuzzy entropy
(IEEE Transactions on Fuzzy Systems, 2017-10)
Obtaining good classification results using supervised learning methods is critical if we want to obtain a high level of precision in the classification processes. The training data used for the learning process plays a ...
Ingesta dietética y actividad física en el tiempo libre de adultas-mayores en ámbito rural mediterráneo
(Archivos Latinoamericanos de Nutricion, 2016-12)
Elderly women in rural areas have a strong role in household and farming work, and they show food intake and use of leisure time. It is interesting to compare the differences between groups of elderly women of rural villages ...
Strategy-focused writing instruction: Just observing and reflecting on a model benefits 6th grade students
(Contemporary Educational Psychology, 2015-04)
Three groups of typically-developing 6th grade students (total N = 62) each completed strategy-focused writing training. Using a combined lagged-group and cross-panel design we assessed the effectiveness of a sequence of ...
Extended convergence results for the Newton–Kantorovich iteration
(Journal of Computational and Applied Mathematics, 2015-10)
We present new semilocal and local convergence results for the Newton–Kantorovich method. These new results extend the applicability of the Newton–Kantorovich method on approximate zeros by improving the convergence domain ...
Software Processes and Methodologies Modeling Language -SPMML- A Holistic Solution for Software Engineering
(IEEE Latin Amerrica Transactions, 2014-06)
This paper presents the Software Processes and Methodologies Modeling Language -SPMML-. This proposal allows to capture the vocabulary of methodologies and software development processes and thus unify them in order to ...
Third-degree anomalies of Traub's method
(Journal of Computational and Applied Mathematics, 2017-01)
Traub’s method is a tough competitor of Newton’s scheme for solving nonlinear equations as well as nonlinear systems. Due to its third-order convergence and its low computational cost, it is a good procedure to be applied ...
