Impact of particle shape on the morphology of noctilucent clouds [PDF]

open access: yesAtmospheric Chemistry and Physics, 2015
Noctilucent clouds (NLCs) occur during summer in the polar region at altitudes around 83 km. They consist of ice particles with a typical size around 50 nm.

Spiral magnetic domain structure in cylindrically-shaped microwires [PDF]

open access: yesScientific Reports, 2018
AbstractIdentification and characterisation of novel and unusual magnetization states remains a topic of research in modern magnetism. Recently, control of the magnetization state between the surface and volume in cylindrical microwires with the giant magneto-impedance effect has been demonstrated.

Scaling instability of the buckling load in axially compressed circular cylindrical shells

open access: yes, 2014
In this paper we initiate a program of rigorous analytical investigation of the paradoxical buckling behavior of circular cylindrical shells under axial compression.

The optimisation of shot peen forming processes [PDF]

open access: yes, 2008
An optimisation method based on an effective process model is presented. The calibrated and verified process model simulates peening on realistic components and provides a non-linear relationship between peening parameters and deflections.

Cylindrical Planetary Nebulae. I. Flow from an Irradiated Ring

open access: yesGalaxies, 2022
Many bipolar nebulae with a pronounced cylindrical shape, such as Henize 3-401, show no indication whatsoever of interaction between a disk and a stellar wind, or a jet on the nebular axis.

Collapse and Fragmentation of Magnetized Cylindrical Clouds [PDF]

open access: yes, 1993
Gravitational collapse of the cylindrical elongated cloud is studied by numerical magnetohydrodynamical simulations. In the infinitely long cloud in hydrostatic configuration, small perturbations grow by the gravitational instability.

Ear height control by die radius shape in cylindrical deep drawing [PDF]

open access: yesMATEC Web of Conferences
This study presents the relationship between die radius shape and anisotropy that suppresses ear height in cylindrical deep drawing. In deep drawing, the cup is formed with irregularities on the edge, called “earing”, due to the anisotropy of sheet ...

Rate of Entropy Production in Evolving Interfaces and Membranes under Astigmatic Kinematics: Shape Evolution in Geometric-Dissipation Landscapes

open access: yesEntropy, 2020
This paper presents theory and simulation of viscous dissipation in evolving interfaces and membranes under kinematic conditions, known as astigmatic flow, ubiquitous during growth processes in nature. The essential aim is to characterize and explain the

Morphological characteristics of hydraulic punching holes and optimization of gas extraction parameters

open access: yesMeikuang Anquan, 2023
At present, in drilling design and evaluation, the shape of hydraulic flushing hole is usually equivalent to cylinder, which is one of the important bases to determine the effective extraction radius.

Shapes and textures of ferromagnetic liquid droplets [PDF]

open access: yes, 2001
Theoretical calculations, computer simulations and experiments indicate the possible existence of a ferromagnetic liquid state. Should such a state exist, demagnetization effects would force a nontrivial magnetization texture governed by the shape of the
