Regularidad local del Mercado de índices para la crisis económica de 2008
Regularidad local del Mercado de índices para la crisis económica de 2008
(2012-03-08)
There is evidence that signals from financial markets, such as stock indices, interest rates or commodities, have a multifractal nature. In recent years, many efforts have been made to relate the inefficiency of markets ...
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 ...
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 ...
Co-occurrence Matrix and fractal dimension for image segmentation
Matriz de co-ocurrencia y dimensión fractal en segmentación de imágenes
(2012-03-08)
One of the most important tasks in image processing problem and machine vision is object recognition, and the success of many proposed methods relies on a suitable choice of algorithm for the segmentation of an image. This ...

An existence theorem for the Boltzmann Equation with force term and small initial data is proved in an $L^{1}$ setting
Influence Factors in Private Investment in El Salvador
Factores que Inciden en la Inversión Privada en El Salvador
(2012-03-12)
According to many empirical studies, one aspect that determines the foundations of economic cycles in the short and medium term is the investment of capital goods since it belongs to an aggregate demand and explains the ...
K-finite decidable objects and finite cardinals in an arbitrary topos
Objetos K-finitos decidibles y cardinales finitos en un topos arbitrario
(2012-03-08)
In an elemetary topos $\varepsilo$, we prove that the class of K-finite decidable objects is the same to the class of finite cardinals in E if and only if every K-finite decidable object X such that $X \longrightarrow 1$ ...
Ttsunami. An Interesting Mathematical Problem
Tsunami. Un Problema Matemáticamente Interesant
(2012-03-12)
We present some key aspects regarding the mathematics and the computational tool that support the complex description of the physical process tsunami from two specific approaches. In particular, it addresses analytically ...
On the Cramér–Von Mises Statistic
Sobre el Estadístico de Cramér–Von Mises
(2012-03-11)
Probably, one of the most useful criterions in order to compare distribution functions is the one introduced by the researchers Harald Cramér and Richard Edler von Mises which is known as Cramérvon Mises criterion $(C_M)$. ...
