Zariski Closures and Subgroup Separability [PDF]

open access: yes, 2016
The main result of this article is a refinement of the well-known subgroup separability results of Hall and Scott for free and surface groups. We show that for any finitely generated subgroup, there is a finite dimensional representation of the free or ...

Viscous free-surface flows

open access: yes, 2022
This thesis investigates several free-surface phenomena to illustrate the role of viscous stresses. In part I (chapters 1-4), we study the impact of spherical liquid drops on non-wetting substrates. After impact on a rigid substrate, a falling liquid drop deforms and spreads, owing to the normal reaction force.

Microscopic Observation of Plastic Deformation of Polycrystalline Aluminum by Laser Scanning Microscope [PDF]

open access: yes, 2001
Free surface of polycrystalline metal becomes roughened after plastic deformation. The surface roughening is closely related to the inhomogeneity of polycrystalline metals, that is, to the inhomogeneous plastic deformation of respective grains.

DRÆM – A discriminatively trained reconstruction embedding for surface anomaly detection [PDF]

open access: yesIEEE International Conference on Computer Vision, 2021
Visual surface anomaly detection aims to detect local image regions that significantly deviate from normal appearance. Recent surface anomaly detection methods rely on generative models to accurately reconstruct the normal areas and to fail on anomalies.

AdaScape 1.0: a coupled modelling tool to investigate the links between tectonics, climate, and biodiversity [PDF]

open access: yesGeoscientific Model Development, 2023
The interplay between tectonics and climate is known to impact the evolution and distribution of life forms, leading to present-day patterns of biodiversity.

New insights into the properties of pubescent surfaces: peach fruit as model [PDF]

open access: yes, 2011
The surface of peach (Prunus persica ‘Calrico’) is covered by a dense indumentum, which may serve various protective purposes. With the aim of relating structure to function, the chemical composition, morphology, and hydrophobicity of the peach skin was ...

A Micropump Driven by Marangoni Effect

open access: yesJournal of Thermal Science and Technology, 2008
A micropump driven by the thermocapillary convection is proposed. The purpose of this study is to examine the flow structure in liquid region and the effect of the geometry on the performance of the present micropump. There are two significant advantages

Investigation of Free Surface Turbulence Damping in RANS Simulations for Complex Free Surface Flows

open access: yesWater, 2019
The modelling of complex free surface flows over weirs and in the vicinity of bridge piers is presented in a numerical model emulating open channel flow based on the Reynolds Averaged Navier-Stokes (RANS) equations.

Hydrodynamic Forces of a Semi-Submerged Cylinder in an Oscillatory Flow

open access: yesApplied Sciences, 2020
This work experimentally investigated the performance of hydrodynamic forces on a semi-submerged cylinder under an oscillatory flow. To generate the equivalent oscillatory flow, the semi-submerged cylinder is forced to oscillate in several combinations ...

Adaptive finite element simulation of three-dimensional surface tension dominated free-surface flow problems [PDF]

open access: yes, 2005
An arbitrary Lagrangian--Eulerian finite element method is described for the solution of time-dependent, three-dimensional, free-surface flow problems.
