Este autor es denominado por DidiHuberman (144) como "a man very attentive to the phenomenology of a visible of which he was nonetheless wary, a scientist extraordinarily quick to question the certainties of the very science that he practiced, an individual who, with rare resolve, pursued the dangerous adventure of grounding a nonspecular
knowledge, a knowledge capable of thinking the work of not-knowledge within him".
With the increasing of correlation length, the BSC decreases both at specular and nonspecular
direction, while the specular peak becomes wider.
In lotal, eight surface conditions were evaluated; these conditions involved the use of a standard stainless steel (STAVAX, HRc53; UDDEHOLM KK) mirrored surface, three stainless steel mirrored surfaces with various coatings, and four stainless steel surfaces with different degrees of nonspecular
roughness (see Table 1).
To address this problem, a method was defined to quantify solar gains through windows with nonspecular shading devices, termed complex fenestration systems (CFS), that bridged the gap between expensive solar calorimeter measurements and first-principles analytical models [Klems 1994a].
Bidirectional transmittance and reflectance or scattering function (BSDF) data for nonspecular devices is critical for routine implementation of this method and obtaining such data has been and continues to be a nontrivial task.
Either the specula can still radiate effectively under these shielded conditions--the pronota and swollen nonspecular
tegmina being viewed as baffles, or they bring about effective secondary radiation by the pronotal projections and the nonspecular
regions of the tegmina.
Added complexity results from the presence of a nonspecular
layer because beam radiation can be converted to diffuse radiation.
To ascertain the specular and nonspecular
scattering distribution from the coating and the substrate surfaces, light scattering measurements were performed on both exposed and unexposed sections of the PVDF paint specimens, using a newly constructed light scattering instrument located in the NIST Building and Fire Research Laboratory.
The presence of an absorption pigment - either coated onto the interference pigment or used in conjunction with it - produces intense specular reflection colors that give way to the color of the absorption pigment at nonspecular
11) To avoid any disturbing glare, both sides of the perforated panels have nonspecular
matte surface rather then glossy texture.
Using the newly constructed light scattering instrument at NIST, optical scattering measurements on a single scratch at various scattering geometries collecting both the specular and nonspecular
intensities were conducted.
