Mathematical Model of Piston Ring Sealing in Combustion Engine

open access: yesPolish Maritime Research, 2015
This paper presents a mathematical model of piston-rings-cylinder sealing (TPC) of a combustion engine. The developed model is an itegrated model of gas flow through gaps in TPC unit, displacements and twisting motions of piston rings in ring grooves as ...

Method for determining eigen numbers in heat conduction problems for a cylinder

open access: yesИзвестия высших учебных заведений: Проблемы энергетики, 2023
RELEVANCE. Due to the difficulties of finding eigenvalues and proper functions for bodies with axial (cylinder) and central (ball) symmetries defined in classical methods from the edge Sturm-Liouville problems, including Bessel equations whose exact ...

Digital disease management programme reduces chronic gastrointestinal symptoms among racially and socially vulnerable populations

open access: yesBMJ Open Gastroenterology
Objective Considerable disparities exist in access to gastrointestinal (GI) care and digestive outcomes across gender, racial, and socioeconomic groups. We evaluated (1) whether adults with chronic GI symptoms from diverse demographic groups would use a ...

EQUIVARIANT HARMONIC CYLINDERS [PDF]

open access: yesThe Quarterly Journal of Mathematics, 2006
We prove that a primitive harmonic map is equivariant if and only if it admits a holomorphic potential of degree one. We investigate when the equivariant harmonic map is periodic, and as an application discuss constant mean curvature cylinders with screw motion symmetries.

Curve shortening by short rulers

open access: yesESAIM: Proceedings and Surveys, 2014
The aim is to construct a straight line between the two endpoints of a rectifiable curve using only a ruler, which is too short to connect them directly.

Synchrotron radiation inside a dielectric cylinder

open access: yes, 2011
We investigate the electromagnetic fields generated by a charged particle rotating inside a dielectric cylinder immersed into a homogeneous medium. The expressions for the bound modes of the radiation field are derived in both interior and exterior ...
