Grid Peeling of Parabolas

open access: yesCoRR
Grid peeling is the process of repeatedly removing the convex hull vertices of the grid-points that lie inside a given convex curve. It has been conjectured that, for a more and more refined grid, grid peeling converges to a continuous process, the affine curve-shortening flow, which deforms the curve based on the curvature.

The Reflection Property of a Parabola

open access: yes, 2016
The resource presents the reflection property of a parabola, where you can visualize a segment parallel to the guideline of the parabola, representing a flat wave of light that goes into the parabolic reflector and is reflected through the parabola in ...

UNA SORPRENDENTE PROPRIETA' DELLA PARABOLA

open access: yes, 2017
Nell'articolo si dimostra una "sorprendente" proprieta' della parabola. Considerati tre punti su una parabola e condotte da essi le tangenti, queste individuano un triangolo. La circonferenza ad esso circoscritta passa per il fuoco della parabola.

Univerzalna parabola

open access: yes, 2018
We develop classical properties, as well as some novel facts, for the parabola using the more general framework of rational trigonometry. This extends the study of this conic to general fields.Dokazujemo neka klasična svojstva kao i neke nove činjenice o
