      Piza Volio, Eduardo (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. ...

      We study the personnel selection problem by the application of techniques of computing intelligence for the classification of psychological patterns. The system is based on the psychological test 16-PF, for the extraction ...
    • Selective methodology of population dynamics for optimizing a multiobjective environment of job shop production 

      Ruiz, Santiago; Castrillón, Omar Danilo; Sarache, William Ariel (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 ...
    • Sensibility concept for the discrete case in the cost sharing problem 

      Hernández Lamoneda, Luis; Macías Ponce, Julio Cesar; Sánchez Sánchez, Francisco (2013-08-29)
      Suppose that a vector is produced jointly. We will consider the problem of dividing the cost of production among a group of components. In this paper we characterized a solution through two axioms, s-sensibility and ...
    • Sensor Fusion Using Entropic measures of Dependence 

      Deignan, Paul B. (2011-07-26)
      As opposed to standard methods of association which rely on measures of central dispersion, entropic measures quantify multivalued relations. This distinction is especially important when high fidelity models of the sensed ...
    • Series de Fourier aplicadas a problemas de cálculo de variaciones con retardo 

      Salazar Solórzano, Lorena (2012-03-22)
      In this article we present an approximation of the minimizing function of the functional    J[x]=\int_0^T F(t,X(t),X(t-\tau),\dot{X}(t))dtby approximating X(t) with Cosine Fourier series expansions X_n(t). We give conditions ...
    • Shapley's value for fuzzy games 

      Alvarado Sibaja, Raúl (2009-02-18)
      This is the continuation of a previous article titled "Fuzzy Games", where I defined a new type of games based on the Multilinear extensions f, of characteristic functions and most of standard theorems for cooperative games ...
    • Shipment consolidation by terminals and vehicles
