  • Modelo Multifractal Aplicado al Riego 

    Mercado Escalante, José Roberto; Aldama R., Álvaro Alberto; Íñiguez C, Mauro; Mejía G, Miguel Ángel (2012-03-02)
    We define the binomial multifractal distribution as an expression of a law of small numbers. We studied a form of evaluation or design of a distribution system in an irrigation district by determining its conduction capacity ...
  • Artificial Neural Network Predictions of Water Levels in a Gulf of Mexico Shallow Embayment 

    Bowles, Zack; Tissot, Philippe E. Tissot; Michaud, Patrick; Sadovski, Alexey (2012-03-01)
    Tide tables are the method of choice for water level predictions in most coastal regions. However, for many locations along the coast of the Gulf of Mexico, tide tables do not meet United States National Ocean Service (NOS) ...
  • Program Implementation of the Rating Methods of Preference Ranking 

    Torres, Kelly; Sadovski, Alexey; Steidley, Carl W. (2012-03-02)
    Tide charts, based upon harmonic analysis, is the general method of choice for predicting water levels. In the shallow waters of the Gulf of Mexico, however, tide charts are woefully inadequate for the prediction of water ...
  • Estimating Parameters of Gumbel Distribution using the Methods of Moments, probability weighted Moments and maximum likelihood 

    Mahdi, Smail; Cenac, Myrtene (2012-03-02)
    We derive here estimators for the parameters of the Gumbel distribution using three estimating methods, namely, the probability weighted moments, the moment and the maximum likelihood methods. Furthermore, we compare the ...
  • Comparison of Gap Interpolation Methodologies for water Level time Series using perl/pdl 

    Mostella, Aimee; Sadovski, Alexey; Duff, Scott; Michaud, Patrick; Tissot, Philippe E. Tissot; Steidley, Carl W. (2012-03-02)
    Extensive time series of measurements are often essential to evaluate long term changes and averages such as tidal datums and sea level rises. As such, gaps in time series data restrict the type and extent of modeling and ...
  • Scattering of e Polarized Whispering-Gallery mode from Concave Boundary 

    Anyutin, Alexander P.; Stasevich, V.I. (2012-03-01)
    In this work we present numerical results for the 2D problem of scattering E polarised whispering-gallery mode from concave convex perfectly conducting boundary. The results were obtained by applying the developed method ...
  • Term Structure of Interest Rates 

    Stradi, Benito A. (2012-03-02)
    The risk free rate on bonds is a very important quantity that allows calculation of premium values on bonds. This quantity of stochastic nature has been modeled with different degrees of sophistication. This paper reviews ...
  • Un Modelo Matemático para la bola de Fútbol 

    Escalante, René; Pacheco, Francisco (2012-03-01)
    This work refers to the analysis, study and resolution of the mathematical problem involved in the design and construction of the cover of a ball, such as the ones used in sports, in order to achieve a ball with optimal ...
  • Un Algoritmo Evolutivo para Resolver el Problema de Coloración Robusta 

    Lara Velázquez, Pedro; Gutiérrez Andrade, Miguel Ángel; Ramírez Rodríguez, Javier; López Bracho, Rafael (2012-03-22)
    Let G and \bar{G} be two complementary graphs. Given a penalty function defined over the edges of \bar{G}, it is said that the rigidity of a k-coloring of G is the summation ofthe penalties of the edges of G that join ...
  • Una propuesta de Modelamiento para los Sistemas de Recompensa 

    de los Cobos Silva, Sergio Gerardo; Brunet Icart, Ignasi; Pérez Salvador, Blanca Rosa; González Santoyo, Federico; Flores Romero, Beatriz (2012-03-01)
    One of the most important subjects of interest, in nearly any human activity, is the perception of salary. It could even be said that the decision of following a career depends deeply on the perspective that the individual ...
  • Indentificación de Fases de la Diabetes Espontánea de un Biomodelo Murino mediante Análisis Multidimensional de Datos

    Biomodels used in the study of diabetes allow to evaluate genetic and environmental factors. Our aim was to characterize individuals of eSS, a genetically diabetic line of rats. We applied multivariate analysis, using the ...
  • One-Sided Confidence Interval Estimation for Weibull Shape and Scale Parameters 

    Mahdi, Smail (2012-03-02)
    In this paper, we consider the problem of one-sided conditional and unconditional interval estimation for the scale and shape parameters in a two-parameter Weibull model. The statistical inference is based upon the pivots ...
