A study on the variation of the spectral bidirectional reflectance distribution function (BRDF) of four diffuse reflectance standards (matte ceramic, BaSO(4), Spectralon, and white Russian opal glass) is accomplished through this work. Spectral BRDF measurements were carried out and, using principal components analysis, its spectral and geometrical variation respect to a reference geometry was ...

We describe an imaging scatterometer allowing hemispherical reflectance measurements as a function of the angle of incidence. The heart of the scatterometer is an ellipsoidal reflector, which compresses the hemispherical reflection into a cone-shaped beam that can be imaged by a normal optical system. The instrument's performance is illustrated by measurements of the scattering profiles of the ...

Taking into account some basic epistemological considerations on psychoanalysis by Ignacio Matte Blanco, it is possible to deduce some first simple remarks on certain logical aspects of schizophrenic reasoning. Further remarks on mathematical thought are also made in the light of what established, taking into account the comparison with the schizophrenia pattern. Ignacio Matte Blanco (1908-1995...

When analyzing the RGB distribution of colors in natural images we notice that they are organized into spatial structures. This observation is not new, quoting Omer and Werman in [5]: “... when looking at the RGB histogram of real world images, two important facts can clearly be observed; The histogram is very sparse, and it is structured.[...] This is because the colors of almost any given sce...

Single particle experiments were carried out in the present study. An industrial copper matte powder, containing 68.04 wt.% Cu, 0.50 Se and 0.08 Te was taken as starting material. phase assemblies distribution behaviors systematically investigated air atmosphere. It found that reported to blister copper, matte, oxide phase, whilst will enrich phases, including phases Fe-Si-Te-O, Ca-Fe-Te-O, Ca-...
