Caracterización espectral de un escáner a partir de las señales RGB y HSV

Carlos J. Finlay y Barrés (1833-1915).

Médico y biólogo cubano. Estudió en Estados Unidos, graduándose en 1855 por el Jefferson Medical College de Filadelfia, para volver después a Cuba. Ya en 1868 propuso la adopción de medidas profilácticas y sanitarias durante una epidemia de cólera, sin mucho éxito. Sin embargo, su principal trabajo consistió en dilucidar cómo se producía la transmisión de la fiebre amarilla por los mosquitos. C...

Connections between C(X) and C(Y), where Y is a subspace of X

In this paper, we introduce a method by which we can find a close connection between the set of prime $z$-ideals of $C(X)$ and the same of $C(Y)$, for some special subset $Y$ of $X$. For instance, if $Y=Coz(f)$ for some $fin C(X)$, then there exists a one-to-one correspondence between the set of prime $z$-ideals of $C(Y)$ and the set of prime $z$-ideals of $C(X)$ not containing $f$. Moreover, c...

The Y(4260) as a J/ψK ¯ K system.

A study of the J/ψππ and J/ψKK̄ systems, treating them as coupled channels, has been made by solving the Faddeev equations, with the purpose of investigating the possibility of generation of the JPC = 1−−, Y (4260) resonance due to the interaction between these three mesons. In order to do this, we start by solving the Bethe-Salpeter equation for the two pseudoscalar and for the vector-pseudocal...
