Recursive formulas for partition functions
Recursive formulas for partition functions
(2012-03-29)
A family of functions, which share many properties with the classical partition function p(n), is studied. It is explained why these functions may be called “partition functions” and, in particular, some recursive formulas ...
Detecting constraint redundancy in 0-1 linear programming problems
Detecting constraint redundancy in 0-1 linear programming problems
(2009-02-19)
In this paper we present a procedure for obtaining upper bounds on a linear function by means of certain families of packings, coverings and special ordered sets. We also present a new method for detecting redundant ...
Regresion PLS y PCA como Solucion al Problema de Multicolinealidad en Regresion Multiple
Regresion PLS y PCA Como Solución al Problema de Multicolinealidad en Regresion Multiple
(2011-03-18)
We present and compare principal components regression and partial least squares regression, and their solution to the problem of multicollinearity. We illustrate the use of both techniques, and demonstrate the superiority ...
Joint Kalman–Haar Algorithm Applied to Signal Processing
Algoritmo conjunto Kalman–Haar aplicado al procesamiento de señales
(2012-03-08)
Under the analysis of signals disturbed by noise, in this paper we propose a working methodology aimed to seize the best estimate of combining Kalman filtering with the characterization that is achieved by applying a ...
A dichotomous property of the total variation of a process with independent increments
(2009-02-19)
We establish a property for the total variation of a cad-lag process with independent increments wich is dichotomous in the sense that only two alternatives are possible. For this purpose we introduce the methods of ...
Métodos de superficie Multirespuesta: Un Estudio Comparativo
Métodos de superficie Multirespuesta: Un Estudio Comparativo
(2011-04-29)
The simultaneous optimization problem may not to have a complete satisfactory solution from the point of view of the individual responses, in the sense that individual optimums are different respect to global optimum; but ...
Parallelization of a Quantum-Classic Hybrid Model For Nanoscale Semiconductor Devices
Paralelización del modelo Híbrido Clásico-Cuántico para un Dispositivo Semiconductor Mosfet Nanométrico
(2011-07-26)
The expensive reengineering of the sequential software and the difficult parallel programming are two of the many technical and economic obstacles to the wide use of HPC. We investigate the chance to improve in a rapid way ...
Teoría de nudos geométricos e isotopía poligonal
Teoría de nudos geométricos e isotopía poligonal
(2009-02-19)
The space of n-sided polygons embedded in euclidean three-space consists of a smoothmanifold in which points correspond to piecewise linear or “geometric” knots, while pathscorrespond to isotopies which preserve the geometric ...
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 ...
Estimation of General Equilibium Model in Dynamic Economies using Markov Chain Monte Carlo Methods
Estimación de Modelos de Equilibrio General en Economías Dinámicas por Métodos de Monte Carlo y Cadenas de Markov
(2012-03-08)
This paper describes a general procedure to do Bayesian inference based on the likelihood evaluation of the stochastic general equilibrium models (MEGE) through Markov Chain Monte Carlo methods (MCMC). The proposed methodology ...
