Optimisation of shovel-truck haulage system in an open pit using queuing approach
Published in Arabian Journal of Geosciences
Open-pit mining operations involve loading and hauling of material from the pit to the processing plant or waste dump depending on the ore grade. These two activities account for more than 50% of total operating costs of the mine. There are several loading and hauling systems that are employed depending on the geometry of the ore body. This study a...
Sketched learning for image denoising
The Expected Patch Log-Likelihood algorithm (EPLL) and its extensions have shown good performances for image denoising. It estimates a Gaussian mixture model (GMM) from a training database of image patches and it uses the GMM as a prior for denoising. In this work, we adapt the sketching framework to carry out the compressive estimation of Gaussian...

Pore-by-pore modelling, validation and prediction of waterflooding in oil-wet rocks using dynamic synchrotron data
We predict waterflood displacement on a pore-by-pore basis using pore network modelling. The pore structure is captured by a high-resolution image. We then use an energy balance applied to images of the displacement to assign an average contact angle, and then modify the local pore-scale contact angles in the model about this mean to match the obse...

Gestion des congestions et prise de décision dans les réseaux électriques maillés en utilisant des batteries électriques...
Le paysage de la production électrique connaît aujourd’hui une modification profonde du fait du plein essor des énergies renouvelables. La partie de la production qui est caractérisée comme intermittente et éparse sur les réseaux est de plus en plus présente et crée de nouvelles contraintes de saturation des réseaux électriques de transport, nommée...
An end-to-end approach of statistical tolerancing under industrial constraints : Contribution to the design/industrial v...
In the manufacturing process of a product, various assembly steps are necessary. Several types of requirements have to be met at each level and involve considerations about dimensional uncertainties on the parts to be assembled. Tolerancing is the activity in charge of the management of these uncertainties and takes place both in the product develo...
Within-country age-based prioritisation, global allocation, and public health impact of a vaccine against SARS-CoV-2: a ...
...
The worldwide endeavour to develop safe and effective COVID-19 vaccines has been extraordinary, and vaccination is now underway in many countries. However, the doses available in 2021 are likely to be limited. We extended a mathematical model of SARS-CoV-2 transmission across different country settings to evaluate the public health impact of potent...
Radiation dose management systems-requirements and recommendations for users from the ESR EuroSafe Imaging initiative.
...Published in European radiology
The European Directive 2013/59/Euratom requires member states of the European Union to ensure justification and optimisation of radiological procedures and store information on patient exposure for analysis and quality assurance. The EuroSafe Imaging campaign of the European Society of Radiology created a working group (WG) on "Dose Management" wit...
