Approximation of conic sections by weighted Lupaş post-quantum Bézier curves

open access: yesDemonstratio Mathematica, 2022
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.

Construction of a family of non-stationary combined ternary subdivision schemes reproducing exponential polynomials

open access: yesOpen Mathematics, 2021
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

open access: yesArray, 2020
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

Facial expression video generation based-on spatio-temporal convolutional GAN: FEV-GAN

open access: yesIntelligent Systems with Applications, 2022
Facial expression generation has always been an intriguing task for scientists and researchers all over the globe. In this context, we present our novel approach for generating videos of the six basic facial expressions.

The growth, spread, and mutation of internet phenomena: A study of memes

open access: yesResults in Applied Mathematics, 2020
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

The best uniform quadratic approximation of circular arcs with high accuracy

open access: yesOpen Mathematics, 2016
In this article, the issue of the best uniform approximation of circular arcs with parametrically defined polynomial curves is considered. The best uniform approximation of degree 2 to a circular arc is given in explicit form.

Reflection curves—new computation and rendering techniques

open access: yesInternational Journal of Mathematics and Mathematical Sciences, Volume 2004, Issue 21, Page 1121-1132, 2004., 2004
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

open access: yesOpen Mathematics, 2018
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

open access: yesResults in Physics, 2017
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.
