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

ON THE CONVEXITY OF PIECEWISE-DEFINED FUNCTIONS ∗, ∗∗, ∗∗∗ [PDF]
, 2016 . Functions that are piecewise defined are a common sight in mathematics while convexity is a property especially desired in optimization. Suppose now a piecewise-defined function is convex on each of its defining components — when can we conclude that ...

Reflection curves—new computation and rendering techniques
International 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 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

Quantum coherence of Gaussian states in curved spacetime
Results in Physics, 2019 We study quantum coherence of two-mode Gaussian states in the background of an asymptotically flat black hole. We find that quantum coherence between mode A observed by an inertial observer Alice and mode B observed by an accelerated Bob who hovers near ...

Quantum (q, h)-Bézier surfaces based on bivariate (q, h)-blossoming
Demonstratio Mathematica, 2019 We introduce the (q, h)-blossom of bivariate polynomials, and we define the bivariate (q, h)-Bernstein polynomials and (q, h)-Bézier surfaces on rectangular domains using the tensor product.

A theoretical study on resistance of electrolytic solution: Measurement of electrolytic conductivity
Results in Physics, 2019 We propose a theoretical approach to determine the conductivity of electrolytic solution using sine waveform voltage as a triggering signal. The approach is based on the acquisition of the complex impedance in two-electrode conductance cell by analyzing ...
