Total 8 species of larger foraminifera were recorded including Alveolina Indicatrix
Hottinger 1960  and Nummulites djodjokartae Martin 1881  (reported first time from Chorgali Formation of this area).
Also, a graphical representation of the optical refractive indicatrix
His topics include the possibility of classifying part surfaces, an analytical method based on second fundamental forms of the contacting part surfaces, indicatrix
of conformity of two smooth regular surfaces in the first order of tangency, and general considerations and special cases for generating enveloping surfaces.
We also consider Tissot's indicatrix
(ellipse) referring to distortions of spherical circles in projection on the plane chart in paragraph 3.
Another visualization tool added specifically for UVGI analysis is the ability to scale a radiometric indicatrix
, displayed with each UVGI fixture, to a given fluence rate threshold.
When light falls normally at the disc, the half-width of the indicatrix
of reflection is about 15[degrees], and when its incident angle is 10[degrees], the maximum amplitude is reduced by about 15% while the half-width increases to 18[degrees].
Moreover, we give some new characterizations of the Mannheim partner curves by considering the spherical indicatrix
of some Frenet vectors of the curves.
Scientists mostly from post-socialist countries describe their experiments or review the literature regarding such matters as paraxial light beams with angular momentum, quasi-ballistic light scattering on particulate media, a novel single-shot technique of micro-nano patterning in single-step through selective laser ablation, optical design techniques in developing current eye models, optical waves in a medium with a rotating optical indicatrix
, and a geometrical-optics analogue of an astigmatic elliptic Gaussian beam.
To better imagine optical relationships, the model of the indicatrix
has proven very useful.
p] denotes the indicatrix
row-vector of state p) and two matrices [R.
The tangent equation of the indicatrix
in the space of the non-degenerated polynumbers [P.
This curve is called the tangent spherical image or tangent indicatrix
of the curve [beta] in [E.
