Este proyecto trata del diseño y de la programación de una matriz de leds en forma de cubo. Para llevar a cabo este proyecto ha sido necesario realizar un estudio de los diferentes micro controladores PIC existentes en ...

Spectral properties of special matrices matrices have been widely applied. We focus on monomial matrices over a finite field $F_{p}$, $p \neq 2$. We describe a way to find the minimal annihilating polynomial, a set of ...

Se presenta una experiencia de aprendizaje de aritmética modular contextualizada en el mundo de la seguridad informática. Todo ello bajo el hilo conductor de una hipotética historia, presentada como un juego de ordenador, ...

The main aim is to estimate the noncentrality matrix of a noncentral Wishart distribution. The method used is Leung’s but generalized to a matrix loss function. Parallelly Leung’s scalar noncentral Wishart identity is ...

Este estudio surge como respuesta a un ejercicio propuesto por la Cátedra de Estadística de la E.T.S.E.I.B. Nuestra propuesta consiste en aplicar el método de los diseños factoriales de experimentos a dos niveles, ensayando ...

We present here the necessary and sufficient conditions for the invertibility of tridiagonal matrices, commonly named Jacobi matrices, and explicitly compute their inverse. The techniques we use are related with the solution ...

Kautz digraphs K(d,l) are a well-known family of dense digraphs, widely studied as a good model for interconnection networks. Closely related with these, the cyclic Kautz digraphs CK(d,l) were recently introduced by Böhmová, ...

OD matrices that describe mobility patterns provide major input to most transport analysis models. Since OD matrices are not yet directly observable, they are usually estimated indirectly. Data from new sources such as ...

Given the Laplacian matrix associated to a weighted graph and given x a single vertex of it, the bottleneck matrix (related to x) is the inverse matrix of the sub matrix of the Laplacian obtained by eliminating the row ...
