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 ...
INTERACTIVE MULTIOBJECTIVE TABU/SCATTER SEARCH BASED ON REFERENCE POINT
BÚSQUEDA TABÚ/DISPERSA MULTIOBJETIVO INTERACTIVAS BASADAS EN PUNTO DE REFERENCIA
(2014-07-01)
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 ...
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 ...
MORTALITY AMONG YOUNG NICARAGUAN IMMIGRANTS TO COSTA RICA: AN APPLICATION OF GEOGRAPHICALLY WEIGHTED STATISTICAL REGRESSION
MORTALIDAD ENTRE LOS INMIGRANTES NICARAGÜENSES EN COSTA RICA: UNA APLICACIÓN DE LA REGRESIÓN GEOGRÁFICA PONDERADA
(2014-07-01)
This paper applies a geographically weighted statistical regression (GWR) model to young Nicaraguan immigrant homicides in Costa Rica during the period 1998-2008 and identifies possible covariates. The pa- rameters for the ...
LENSING PROPERTIES OF THE EINASTO PROFILE IN TERMS OF THE MEIJER G FUNCTION
PROPIEDADES DEL EFECTO LENTE PARA EL PERFIL DE EINASTO EN TÉRMINOS DE LA FUNCIÓN G DE MEIJER
(2014-07-01)
In N-body simulations of cold dark matter, it has been found that three-parameter models, particularly the Einasto profile, yield better fits to a wide range of dark matter haloes than two parameter models like the ...
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 ...
NONLINEAR FILTERS TO RECONSTRUCT ELECTROCARDIOGRAM SIGNALS
FILTROS NO LINEALES PARA RECONSTRUIR SEÑALES DE ELECTROCARDIOGRAMAS
(2014-07-01)
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 ...
