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
(2015-01-01)
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
(2015-01-01)
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 ...
Local convergence of exact and inexact newton’s methods for subanalytic variational inclusions
Convergencia local de los métodos de newton exacto e inexacto para inclusiones variacionales subanalíticas
(2015-01-01)
This paper deals with the study of an iterative method for solving a variational inclusion of the form 0 ∈ f (x)+F (x) where f is a locally Lipschitz subanalytic function and F is a set-valued map from Rn to the closed ...
Cognitive rhythms and evolutionary algorithms in university timetables scheduling
Ritmos cognitivos y algoritmos evolutivos en la programación de horarios universitarios
(2015-03-18)
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 ...
Infinitely oscillating wavelets and a efficient implementation algorithm based the FFT
Wavelets infinitamente oscilantes y un eficiente algoritmo de implementación basado en la FFT
(2015-01-01)
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 ...
Fourier coefficientes computation in two variables, a distributional version
Cáluculo de Coeficientes de Fourier en dos variables, una versión distribucional
(2015-01-01)
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 ...
TABU SEARCH WITH ASPIRATION CRITERION FOR THE TIMETABLING PROBLEM
BÚSQUEDA TABÚ CON CRITERIO DE ASPIRACIÓN PROBABILÍSTICO APLICADA A LA GENERACIÓN DE HORARIOS ESCOLARES
(2015-01-01)
The aspiration criterion is an imperative element in the Tabu Search, with aspiration-by-default and the aspiration-by-objective the mainly used criteria in the literature. In this paper a new aspiration criterion is ...
Algunas soluciones exactas para la ecuación unidimensional de fokker-planck usando simetrías de lie
Some exact solutions for a unidimensional fokker-planck equation by using lie symmetries
(2015-01-01)
La ecuación de Fokker Planck aparece en el estudio de fenómenos de difusión, procesos estocásticos y mecánica clásica y cuantica. Un caso particular de esta ecuación, ut − uxx − xux − u = 0, es analizada empleando el método ...
Selective methodology of population dynamics for optimizing a multiobjective environment of job shop production
Metodología selectiva de dinámica poblacional para optimizar un ambiente multiobjetivo de producción job shop
(2015-03-18)
This paper develops a methodology based on population genetics to improve the performance of two or more variables in job shop production systems. The methodology applies a genetic algorithm with special features in the ...
OPTIMAL PRODUCTION–SALES STRATEGIES FOR A COMPANY AT CHANGING MARKET PRICE
ESTRATEGIAS ÓPTIMAS DE VENTAS Y PRODUCCIÓN PARA UNA COMPAÑÍA EN UN MERCADO CON PRECIOS CAMBIANTES
(2015-01-01)
In this paper we consider a monopoly producing a consumer good of high demand. Its market price depends on the volume of the produced goods described by the Cobb-Douglas production function. A production-sales activity of ...
