A sinusoidal grating can be viewed as a series of light and dark bars. Here we measure the contrast discrimination thresholds for light and dark bars individually, and find that the contrast discrimination thresholds for the whole sinusoid can be explained as ideal summation of the light and dark bar thresholds. We propose a model for light bar, dark bar, and sinusoidal contrast discrimination ...
Leucites are tetrahedrally coordinated silicate framework structures with some of the silicon cations partially replaced by divalent or trivalent cations. These have general formulae A 2 B Si 5 O 12 and AC 6 ; where is a monovalent alkali metal cation, C cation. In this paper, we report Rietveld refinements three more synthetic leucite analogues stoichiometries Cs NiSi , RbGaSi CsGaSi . Ia $\ba...
This paper presents a new method to investigate plastic deformation of FCC metals in high strain rates. Experimental set up includes two stages gas gun, spherical projectile and target assembly. Target assembly includes front plate, two pressure bars, FCC specimen, three frames and rigid holder. The set-up is carried out according to the following method: a spherical projectile, accelerated to...
