Special software for computing the special functions of wave catastrophes
Software especial para calcular las funciones especiales de catástrofes de olas
The method of ordinary differential equations in the context of calculating the special functions of wave catastrophes is considered. Complementary numerical methods and algorithms are described. The paper shows approaches ...
Fourier coefficientes computation in two variables, a distributional version
Cáluculo de Coeficientes de Fourier en dos variables, una versión distribucional
The present article, by considering the distributional summations of Euler-Maclaurin and a suitable choice of the distribution, results in repre- sentations for the Fourier coefficients in two variables are obtained. These ...
NONLINEAR FILTERS TO RECONSTRUCT ELECTROCARDIOGRAM SIGNALS
FILTROS NO LINEALES PARA RECONSTRUIR SEÑALES DE ELECTROCARDIOGRAMAS
ECG signals have been used in cardiac pathology to detect disease heart. The main objective of this paper is to propose signal filtering techniques to reduce noise, extract information, to reconstruct the states and ...
MATHEMATICAL MODEL FOR TOXIN TRANSPORT IN A MARINE FOOD CHAIN
MODELO MATEMÁTICO DEL TRANSPORTE DE UNA TOXINA EN UNA RED TRÓFICA MARINA
Some cases of poisoning by consumption of contaminated fish, like the Ciguatera poisoning, occur unexpectedly and they are not easy to detect previously since the fish that carry the toxin do not have appearance and/or ...
Cognitive rhythms and evolutionary algorithms in university timetables scheduling
Ritmos cognitivos y algoritmos evolutivos en la programación de horarios universitarios
The main purpose of this research is to design a methodology based on evolutionary algorithms to university timetable scheduling. This methodology will consider the students’ cognitive rhythms, which establish that teaching ...
INTERACTIVE MULTIOBJECTIVE TABU/SCATTER SEARCH BASED ON REFERENCE POINT
BÚSQUEDA TABÚ/DISPERSA MULTIOBJETIVO INTERACTIVAS BASADAS EN PUNTO DE REFERENCIA
This paper presents multiobjective tabu/scatter search architecture with preference information based on reference points for problems of contin- uous nature. Features of this new version are: its interactive behavior, its ...
SUPERIOR ORDER G -STRUCTURES
G -ESTRUCTURAS DE ORDEN SUPERIOR
In this article we study the basic facts about superior order G-structures, then we show that the set of infinitesimally automorphisms of a geometric G-structure is a closed Lie group.
Times of analgesic efficacy of two drugs in the treatment of patients with renal-ureteral colic compared by survival models
Comparación de tiempos de eficacia analgésica de dos fármacos en pacientes con cólico renoureteral empleando modelos de supervivencia
Renourethral colic is a very painful clinical situation that requires a quick diagnosis and treatment. A study was done with patients who were administered two types of analgesics, and whose pain was measured through a ...
An adaptive wavelet-galerkin method for parabolic partial differentia equations
Un método wavelet-Galerkin adaptativo para ecuaciones diferenciales parciales parabólicas
In this paper an Adaptive Wavelet-Galerkin method for the solution of parabolic partial differential equations modeling physical problems with different spatial and temporal scales is developed. A semi-implicit time ...
Infinitely oscillating wavelets and a efficient implementation algorithm based the FFT
Wavelets infinitamente oscilantes y un eficiente algoritmo de implementación basado en la FFT
In this work we present the design of an orthogonal wavelet, infinitely oscillating, located in time with decay 1/|t|n and limited-band. Its appli- cation leads to the signal decomposition in waves of instantaneous, well ...
