To the question of the method of calculating the volume of amphoras [PDF]
Archaeoastronomy and Ancient Technologies, 2020 The article describes the methods for calculating the volume of amphoras used by modern archaeologists, and proposes a new fairly accurate method for calculating the volume of antique sharp-pointed amphoras using the example of narrow-necked light-clay ...

Horticulturae, 2022 Historically, little attention has been paid to the resemblance between seed silhouettes to geometric figures. Cardioid and derivatives, ellipses, heart curves, lemniscates, lenses, lunes, ovals, superellipses, waterdrops, and other figures can be used ...

Journal of Statistical Physics, 2017 We define a continuum percolation model that provides a collection of random ellipses on the plane and study the behavior of the covered set and the vacant set, the one obtained by removing all ellipses. Our model generalizes a construction that appears implicitly in the Poisson cylinder model of Tykesson and Windisch.

Normal pullout bearing characteristics of inclined strip anchor plate in sand
Yantu gongcheng xuebao, 2023 For the inclined burial anchor plate, the researches on the influences of inclination angle on the bearing characteristics are insufficient, and the coupling effects of inclination angle and burial depth controlling the bearing mechanism are also not ...

Ellipses, near ellipses, and harmonic Möbius transformations [PDF]
Proceedings of the American Mathematical Society, 2005 Analytic Möbius transformations take circles to circles. This is their most basic, most celebrated geometric property. In a previous paper [\textit{M.~Chuaqui, P.~Duren} and \textit{B.~ Osgood}, J. Anal. Math. 91, 329--351 (2003; Zbl 1054.31003)], the authors introduced harmonic Möbius transformations as a generalization of Möbius transformations to ...

Buildings, 2021 The aim of this article is to orient the evolution of new architectural forms offering up-to-date scientific support. Unlike the volume, the expression for the lateral area of a regular conoid has not yet been obtained by means of direct integration or a

On a Certain Functional Equation and Its Application to the Schwarz Problem
Mathematics, 2023 The Schwarz problem for J-analytic functions in an ellipse is considered. In this case, the matrix J is assumed to be two-dimensional with different eigenvalues located above the real axis.

Petit cantique de la mécanique du vide dans la bande dessinée
L'Âge d'or, 2023 En bande dessinée, le vide est un élément sémiotiquement consubstantiel à la notion de séquentialité : il est le lieu de l’ellipse spatio‑temporelle inter‑iconique qui permet la progression de case en case.
