Approximation of conic sections by weighted Lupaş post-quantum Bézier curves
This paper deals with weighted Lupaş post-quantum Bernstein blending functions and Bézier curves constructed with the help of bases via (p,q)\left(p,q)-integers. These blending functions form normalized totally positive bases.

In this paper, we propose a family of non-stationary combined ternary (2m+3)\left(2m+3)-point subdivision schemes, which possesses the property of generating/reproducing high-order exponential polynomials.

Narrowly avoided cusp catastrophes in Least Squares Orthogonal Distance Fitting
Computer animation often requires that complex objects need to be modeled by fitting them with simpler shapes such as splines. It is necessary that these simpler shapes respond continuously as the object changes shape. This response can become complex if

The growth, spread, and mutation of internet phenomena: A study of memes
An internet memes is defined as “an image, video, piece of text, etc., typically humorous in nature, that is copied and spread rapidly by Internet users, often with slight variations” (Oxford Living Dictionary, 2018). Such units of information are spread

Reflection curves—new computation and rendering techniques
Reflection curves on surfaces are important tools for free‐form surface interrogation. They are essential for industrial 3D CAD/CAM systems and for rendering purposes. In this note, new approaches regarding the computation and rendering of reflection curves on surfaces are introduced.

Univariate approximating schemes and their non-tensor product generalization
This article deals with univariate binary approximating subdivision schemes and their generalization to non-tensor product bivariate subdivision schemes. The two algorithms are presented with one tension and two integer parameters which generate families

Voltage transients in thin-film InSb Hall sensor
The work is reached to study temperature transients in thin-film Hall sensors. We experimentally study InSb thin-film Hall sensor. We find transients of voltage with amplitude about 10 μV on the sensor ports after current switching.
