Bessel beams are widely used in optical metrology mainly because of their large Rayleigh range (focal length). Radial/azimuthal polarization of such beams is of interest in the fields of material processing, plasma absorption or communication. In this paper an experimental set-up is presented, which generates a Bessel-type vector beam with a spatial polarization, oscillating along the optical a...

The authors investigate to what extent differential equations can describe the dynamics of love relations in masochistic novellas. Unlike previous researchers, they base their analysis not only on psychological credibility. They relate their model to the ideas of literary criticism. The authors compare Ivan Turgenev’s Torrents of Spring with the most famous masochistic novella Venus in Furs by ...

The partial replacement of RDX with AP attention of many researchers. In this paper, Firstly reasons of replacing part of AP with RDX expressed and the influence of replacing part of AP with RDX on the mechanical, safety and ballistic properties of composite solid propellant have been studied. Using of nitramines in the propellant formulations cause to change in the mechanical properties such ...

Congestion control in wireless networks is strongly dependent on the dynamics and instability of wireless links. It is known that TCP experiences serious performance degradation problems in wireless networks. New approaches based on TCP try to overcome these problems but, although their performance is increased, they incur in congestion control errors, since they do not evaluate accurately the ...
