Family of Enneper Minimal Surfaces

open access: yesMathematics, 2018
We consider a family of higher degree Enneper minimal surface E m for positive integers m in the three-dimensional Euclidean space E 3 . We compute algebraic equation, degree and integral free representation of Enneper minimal surface for

Analytical surfaces for ship hulls

open access: yesRUDN Journal of Engineering Research, 2021
The choice of optimal shape of ship hull surface is one of the main problems of ship architects and designs. A choice of the form is based on empirical formulae or on intuition of designers.

A Physically Based Statistical Model With the Parameterized Topographic Effect for Predicting the Weakening of Tropical Cyclones After Landfall Over China

open access: yesGeophysical Research Letters, 2022
Accurate prediction of tropical cyclone (TC) intensity is important but challenging. In this study, a physically based algebraic decay model for predicting TC weakening after landfall over China is introduced, which assumes the TC weakening rate is ...

Correction of distortion in flattened representations of the cortical surface allows prediction of V1-V3 functional organization from anatomy. [PDF]

open access: yesPLoS Computational Biology, 2014
Several domains of neuroscience offer map-like models that link location on the cortical surface to properties of sensory representation. Within cortical visual areas V1, V2, and V3, algebraic transformations can relate position in the visual field to ...

Differentials of the 2nd kind on a product surface

open access: yesInternational Journal of Mathematics and Mathematical Sciences, 1979
This paper deals with the problems of representing an arbitrary double differential of the second kind, defined on a surface which is the topological product of two curves, in terms of the products of simple differentials of the second kind on the two ...

Isomorphism of Compactifications of Vector Bundles Moduli: Nonreduced Moduli

open access: yesМоделирование и анализ информационных систем, 2015
We continue the study of the compactification of the moduli scheme for Gieseker-semistable vector bundles on a nonsingular irreducible projective algebraic surface S with polarization L, by locally free sheaves.

Algebraic expressions for estimating the impact depths of a surface barrier over a homogeneous soil

open access: yesVadose Zone Journal, 2020
Engineered surface barriers are used to isolate subsurface contaminants for effective long‐term containment of waste of a variety of types. The impact depths of a surface barrier are affected by the pre‐barrier recharge rate and the properties of the ...

Quartic surfaces, their bitangents and rational points [PDF]

open access: yesÉpijournal de Géométrie Algébrique, 2023
Let X be a smooth quartic surface not containing lines, defined over a number field K. We prove that there are only finitely many bitangents to X which are defined over K.
