La curtosis o cuarto momento de una distribución, se emplea para describir una distribución y forma parte de algunos contrastes de normalidad. La mayoría de los paquetes estadísticos la incluyen, por lo que su cálculo es ...

This thesis is a study of the quantum properties of multimode entangled photons created by spontaneous parametric down-conversion. More specifically, we attempt to utilize this multimode character in quantum information ...

Here we show that in arbitrary dimensions D >= 3 there are two families of linearized second order Lagrangians describing massive "spin-2" particles via a nonsymmetric rank-2 tensor. They differ from the usual ...

The fourth industrial revolution attemps to produce big changes at social, economic and political levels. The new tecnological context reveals abrupt transformations over the organizations structure and the direvtive mode. ...

A Lagrangian formalism is used to study the motion of a spinning massive particle in Friedmann–Robertson–Walker and G¨odel spacetimes, as well as in a general Schwarzschild-like spacetime and in static spherically ...

In the nonlinear optical process of spontaneous parametric down conversion, a laser beam incident in a nonlinear crystal, generates pairs of photons. In this process energy and momentum are conserved. This process is used ...

A numerical method to compute the viscoelastic melt-spinning model with radial resolutions of temperature and stress fields is formulated and applied to the low speed range. The starting framework is the reduction of the ...
