Valores propios de Dirichlet asociados a la ecuación de Hill con potencial de ruido blanco
Valores propios de Dirichlet asociados a la ecuación de Hill con potencial de ruido blanco
(2009-02-18)
We show that Hill’s equation with white noise potential has a sequence of Dirichlet eigenvalues /lambda n that behaves almost like in the classical case, in the sense that /lambda n - n2/pi 2 has a logarithmic growth coming ...
A Hybrid Random Number Generator(HRNG)
Un Generador Híbrido de Números Aleatorios
(2011-07-29)
The purpose of this paper is to present a novel Hybrid Random Number Generator (HRNG). Here “hybrid” refers to the fact that to construct this generator it is necessary to use 1)physical components – texts – and a physical ...
Preference of effective Factors in suitable selection of Microtunnel boring machines (mtbm) by using the fuzzy analytic hierarchy process (fahp) approach
Preferencia de Factores de Efectividad en la Selección Apropiada de Máquinas Taladradoras de Microtúnel (MTBM) Usando el Enfoque del Proceso Jerárquico Analítico Difuso (FACH)
(2011-07-08)
The development of underground infrastructure, environmental concerns, and economic trend is influencing society. Due to the increasingly critical nature of installations of utility systems especially in congested areas, ...
Optimal Control of Pollution Stock through Ecological Interaction of the Manufacturer and the State
Control Óptimo de Contaminación Almacenada a través de Interacción Ecológica entre el Fabricante y el Estado
(2011-03-18)
A model of an interaction between a manufacturer and the state where the manufacturer produces a single product and the state controls the level of pollution is created and investigated. A local economy with a stock pollution ...
Heuristic for Solving the Multiple Alignment Sequence Problem
Heurística para Solucionar el Problema Alineamiento Múltiple de Secuencias
(2011-03-18)
In this paper we developed a new algorithm for solving the problem of multiple sequence alignment (AM S), which is a hybrid metaheuristic based on harmony search and simulated annealing. The hybrid was validated with the ...
The Decreasing digits and the a, b, c Model: A Proposal for Handling Populations in Shelters
Los Dígitos Decrecientes y el Modelo a, b, c: Una Propuesta para el Manejo de Poblaciones en Albergues
(2011-03-18)
Happened a catastrophe, some one of the impacted population should their move from its homes, toward refuges or shelters. To guarantee the essential services in the shelter, it is necessary to know the population size that ...
Fuzzy Regression VS. Ordinary Least Squares Regression: Case Study
Regresión Borrosa VS. Regresión por Mínimos Cuadrados Ordinarios: Caso de Estudio
(2011-03-18)
The objective of this paper is to disseminate the technique of fuzzy regression and to give a practical example of its use. To this end, classical regression is compared to several fuzzy regression models on a problem ...
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 ...
search of hadamard matrices by turyn sequences
Búsqueda de Matrices de Hadamard a través de Secuencias de Turyn
(2011-07-08)
In this paper we study the Hadamard matrices and some algorithms to generate them. We review some theoretical aspects about Hadamard's conjecture, which asserts that every positive integer multiple of 4 is a Hadamard number. ...
Time-frequency methods based on the wavelet transform
Métodos tiempo-frecuencia basados en la transformada wavelet
(2012-07-01)
The information contained in an analog signal is reveled by its numerical representation. The Fourier pair, in two complementary representations, expounds time and frequency structures. However, to detect and characterize ...
