Effects of biasing on the galaxy power spectrum at large scales

, 2011
n this paper we study the effect of biasing on the power spectrum at large scales. We show that even though non-linear biasing does introduce a white noise contribution on large scales, the $P(k)\propto k^n$ behavior of the matter power spectrum on large

Design of metallic nanoparticles gratings for filtering properties in the visible spectrum

, 2015
Plasmonic resonances in metallic nanoparticles are exploited to create efficient optical filtering functions. A Finite Element Method is used to model metallic nanoparticles gratings.

Interest Points as a Focus Measure in Multi-Spectral Imaging [PDF]

, 2013
A novel multi-spectral focus measure that is based on algorithms for interest point detection, particularly on the FAST (Features from Accelerated Segment Test), Fast Hessian and Harris-Laplace detector, is described in this paper.

Photochromism of dihydroquinolines [PDF]

, 1970
Reversible photochromic reactions, in which absorption spectrum of chemical compound may be shifted by application of visible or ultraviolet light, and then returned to original state by heating, are observed for certain members of 1,2-dihydroquinoline ...
