Thick domain walls in a polynomial approximation [PDF]

open access: yesPhysical Review D, 1995
Relativistic domain walls are studied in the framework of a polynomial approximation to the field interpolating between different vacua and forming the domain wall. In this approach we can calculate evolution of a core and of a width of the domain wall. In the single, cubic polynomial approximation used in this paper, the core obeys Nambu-Goto equation

Investigation of the Geometry of Metal Tube Walls after Necking in Uniaxial Tension

open access: yesMetals, 2017
: In order to characterize the deformation and true stress–strain relation of metal tubes, the geometry of tube walls after necking in uniaxial tension need to be determined. The paper investigated the necking process of metal tube.

Bronchial Wall Thickness in Toll Collectors

open access: yesIndustrial Health, 2010
There is an increasing concern about the possible adverse effects of diesel exhaust particulates on human health. In a diesel exposed occupational group composed of 120 toll collectors, a cross-sectional study was performed to evaluate the chest radiographs and 40 toll collectors were selected for computed tomography examination according to ...

Left Atrium Wall-mapping Application for Wall Thickness Visualisation [PDF]

open access: yesScientific Reports, 2018
AbstractThe measurement method for the LA wall thickness (WT) using cardiac computed tomography (CT) is observer dependent and cannot provide a rapid and comprehensive visualisation of the global LA WT. We aim to develop a LA wall-mapping application to display the global LA WT on a coplanar plane.

Research on the Optimization of TP2 Copper Tube Drawing Process Parameters Based on Particle Swarm Algorithm and Radial Basis Neural Network

open access: yesApplied Sciences
After rolling, TP2 copper tubes exhibit defects such as sawtooth marks, cracks, and uneven wall thickness after joint drawing, which severely affects the quality of the finished copper tubes.

Analysis of the influence of the pipe’s wall thickness on the corrugation of the surface during inductive bending of pipes

open access: yesMATEC Web of Conferences, 2018
The paper presents a calculation model for simulation the technological process of inductive bending of pipes. In the case of an incorrect combination of geometric bending parameters (pipe diameter, bend radius and pipe wall thickness) occurs the ...
