Unknown Parabolas

Chelovek, 2021
This essay describes the powerful effects of my encounter with Valery Podoroga, emphasizing not only Podoroga’s interest in mimesis, but also his own capacity for mimetic openness. It begins autobiographically, recounting Podoroga’s lecture on Andrei Platonov’s “Eunuch of the Soul” at a conference at Duke University in 1990.

Non-autonomous wave solutions for the Gross-Pitaevskii (GP) equation with a parabola external potential in Bose-Einstein condensates

, 2019
A Gross-Pitaevskii (GP) equation with a parabola external potential is considered, and is transformed into a standard nonlinear Schrodinger (NLS) equation.

High-resolution surface shape measurement of parabola antenna reflector by using grating projection method with virtual targets

Acta Astronautica, 2018
In this study, a high-resolution surface shape measurement system incorporating a grating projection method and a virtual-target registration method is constructed as inspection tools for precise large space structures, and the applicability of the ...

Characterisations of the parabola

Mathematical Gazette, 2019
Three familiar properties of a parabola are that it is the locus of points that are equidistant from the focus and the directrix, that it can be created by an intersection of a plane and a cone, and that incoming rays parallel to the axis are reflected ...

A relation between the curvature ellipse and the curvature parabola

Advances in Geometry, 2017
At each point in an immersed surface in ℝ4 there is a curvature ellipse in the normal plane which codifies all the local second order geometry of the surface. Recently, at the singular point of a corank 1 singular surface in ℝ3, a curvature parabola in

Bioassay from two parabolas

Computers in Biology and Medicine, 1993
The paper deals with potency ratio estimation of parallel curve analytic dilution assays in case log dose-response relationship could be reasonably described by a parabola. It comprises: (1) testing the adequacy and validity of the quadratic model by the analysis of variance; and (2) estimation of the relative potency of an unknown in relation to a ...

Parabola

2023
Dal greco παραβολή, “collocazione di una cosa accanto a un’altra”, quindi “comparazione, similitudine”. La parabola è prima di tutto una traiettoria (Galileo) poi una sezione strutturale che si avvicina all’ottimale in termini sia di resistenza sia di rigidezza. Note le parabole in letteratura: narrazioni metaforiche per trasmettere un insegnamento o
