  • L3: the geometry of pseudoquaternions 

    Birman, Graciela Silvia (2009-02-18)
    We introduce pseudoquaternions as an effective tool to describe the vector analysis in L3 , and we use them to characterIze null curves and null cubics in S12 .Keywords: pseudoquaternions, vector analysis, null curves
  • Descomposición de procesos de incrementos independientes en casi intervalos 

    Lobo Segura, Jaime (2009-02-18)
    We introduce the notion independent increment in quasi-intervals. Some properties of the fixed points of these processes are studied, as well as those of the aditive descomposition. Finally, we establish the relation between ...

    We present a computational implementation in MATHEMATICA of the dual Statis method and we use the method for the growth analysis of some kind of sugar cane.Keywords: multivariate date analysis, MATHEMATICA, multiple tables, ...
  • Dinámica de una huella plana turbulenta alejada 

    Grebenev, Vladimir N (2009-02-18)
    From the conservation equation of the quantity of movement and the kinetic energy of the studied turbulence, the dynamics of flat and turbulent path in a non comprehensive liquid environment. In the case of a liquid flow ...
  • 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 ...

  • Isomorfismo de grafos y de funciones lógicas con algunas aplicaciones 

    Bulat, Mijail (2009-02-18)
    A method to solve the isomorphism problem for graphs is suggested, which significantly decreases the number of variants to be checked. Based on the substitution of two successions, the necessary and sufficient conditions ...
