Sub-Riemannian geometry, Hamiltonian dynamics, micro-swimmers, copepod nauplii and copepod robot

open access: yesPacific Journal of Mathematics for Industry, 2018
The objective of this article is to present the seminal concepts and techniques of Sub-Riemannian geometry and Hamiltonian dynamics, complemented by adapted software to analyze the dynamics of the copepod micro-swimmer, where the model of swimming is the

Abrasive Grains Micro Geometry: A Comparison between Two Acquisition Methods

open access: yesProcedia CIRP, 2018
Abstract One of the aspects that makes difficult grinding processes modelling is the non-deterministic nature of the cutting tool, in particular the abrasive grains of the grinding wheel have a random distribution and an undefined geometry that influences the grinding forces. In order to develop a reliable 3D model of the grinding process the actual

Optimization of Microchannel Geometries to Enhance Convection Cooling of Parallel Plate Duct Flow [PDF]

open access: yesEngineering and Technology Journal, 2014
Forced convection heat transfer from arrays of microchannels was considered for fixed volume and fixed pressure drop constraints. Order of magnitude relationships were developed for the optimal dimension of a number of fundamental duct shapes including ...

Heat transfer enhancement in a cross-slot micro-geometry

open access: yesInternational Journal of Thermal Sciences, 2017
Abstract The cross-slot is a common geometric shape in microfluidic applications. In this article we investigate the influence of a purely-inertial flow instability on the enhancement of heat transfer in a cross-slot micro-geometry where symmetry is broken but the flow remains steady.

Auxetic two-dimensional lattice with Poisson's Ratio arbitrarily close to -1

open access: yes, 2014
In this paper we propose a new lattice structure having macroscopic Poisson's ratio arbitrarily close to the stability limit -1. We tested experimentally the effective Poisson's ratio of the micro-structured medium; the uniaxial test has been performed ...

Fine-Grained Material Classification Using Micro-geometry and Reflectance

open access: yes, 2016
In this paper we focus on an understudied computer vision problem, particularly how the micro-geometry and the reflectance of a surface can be used to infer its material. To this end, we introduce a new, publicly available database for fine-grained material classification, consisting of over 2000 surfaces of fabrics (http://ibug.doc.ic.ac.uk/resources ...

Performance impact of honing dynamics on surface finish of precoated cylinder bores [PDF]

open access: yes, 2013
The surface modification of engine cylinder bores with improved sliding properties is often produced by the honing process. This multi-stage process is performed using abrasive stones loaded against the bore with simultaneous rotation and oscillation. To
