New upper bounds on sphere packings I [PDF]
, 2003 We develop an analogue for sphere packing of the linear programming bounds for error-correcting codes, and use it to prove upper bounds for the density of sphere packings, which are the best bounds known at least for dimensions 4 through 36.

Spherical Interpretation of Infiltration from Trickle Irrigation
Agronomy, 2022 The hypothesis of this paper is that infiltration into drip irrigated soils can be described by simple spherical considerations as well as two dimensional (2D) numerical modeling.

, 2016 We construct a family of constant curvature metrics on the Moyal plane and compute the Gauss-Bonnet term for each of them. They arise from the conformal rescaling of the metric in the orthonormal frame approach.

The sphere packing problem in dimension 8The sphere packing problem in dimension 8 [PDF]
, 2016 In this paper we prove that no packing of unit balls in Euclidean space R-8 has density greater than that of the E8-lattice packing.

Axioms, 2022 The process of heat transfer that involves non-Newtonian fluids in porous regions has attracted considerable attention due to its practical application. A mathematical model is proposed for monitoring fluid flow properties and heat transmission in order ...

Acta Physica Sinica (Overseas Edition), 1999 By analyzing the Einstein's equations for the static sphere, we find that there exists a non-singular static configuration whose radius can approach its corresponding horizon size arbitrarily.

Complete intersection singularities of splice type as universal abelian covers [PDF]
, 2004 It has long been known that every quasi-homogeneous normal complex surface singularity with Q-homology sphere link has universal abelian cover a Brieskorn complete intersection singularity.

Mechanism of Drag Reduction by Dimple Structures on a Sphere
Journal of Fluid Science and Technology, 2012 The purpose of the present study is to clarify the mechanism of drag reduction for a sphere with arc type dimples. The sphere has 328 dimples of different depths uniformly distributed on its surface.

Simulation of perspective by nonlinear transformations
Mathematical Modelling and Analysis, 2013 A feature of the brain processing the visualization of objects is such that objects that are much farther away from the eye look smaller than closer objects to the eye.
