ERO2.0 predictions of nickel migration in the JET ITER-Like Wall

open access: yesNuclear Materials and Energy
Nickel transport in the Joint European Torus with the ITER-like wall (JET-ILW) is predicted using the 3D Monte-Carlo code ERO2.0, simulating the erosion and deposition of impurities in 3D geometry and utilizing hydrogenic background plasmas generated by ...

Investigation of deuterium trapping and release in the JET divertor during the third ILW campaign using TDS

open access: yesNuclear Materials and Energy, 2019
Selected set of samples from JET ITER-Like Wall (JET-ILW) divertor tiles exposed in 2015–2016 has been analysed using Thermal Desorption Spectrometry (TDS).

UCanWBGT: urban street canyon heat stress calculation for weather and climate models

open access: yesQuarterly Journal of the Royal Meteorological Society, EarlyView.
This work introduces UCanWBGT, a new model to calculate wet‐bulb globe temperature in an urban environment, suitable for use with weather and climate model data. We present the model, then verify its performance against observations made in the streets of Paris during heatwave conditions.

Characterization of avian eggshell waste aiming its use in a ceramic wall tile paste Caracterização de resíduo de casca de ovo visando seu aproveitamento em revestimento cerâmico poroso

open access: yesCerâmica, 2006
In Brazil, the food industry generates every year huge amounts of avian eggshell waste, and a critical question is to find an adequate use for this waste.

Parameter investigation for urban surface‐energy balance: A large‐eddy simulation study

open access: yesQuarterly Journal of the Royal Meteorological Society, EarlyView.
Large eddy simulation modelling is used to investigate the variation in surface‐energy balance (SEB) across an ensemble of morphometrically identical urban geometries. The geometries have the same plan‐area fraction, vegetated fraction, and frontal‐area index, but are unique in terms of building and green‐space layout.

The optimal decision of insulation in cladding structures for energy efficient buildings

open access: yesMATEC Web of Conferences, 2017
Execution of thermal insulation for enclosing structures of residential properties is a sophisticated part of the thermal protection. The choice of insulation materials for external walls is one of the main ways to increase the performance of heat ...

Autonomous Navigation in Large‐Scale Underground Environments Based on a Purely Topological Understanding of Tunnel Networks

open access: yesJournal of Field Robotics, EarlyView.
ABSTRACT This work presents a non‐geometrical navigation approach based on a purely topological understanding of underground environments. By conceptualizing subterranean scenarios as a set of tunnels that intersect with each other, and taking a navigation approach based on topological instructions, we simplify the navigation problem to the sequential ...

Wall‐to‐wall Amazon forest height mapping with Planet NICFI, Aerial LiDAR, and a U‐Net regression model

open access: yesRemote Sensing in Ecology and Conservation, EarlyView.
Tree canopy height is a key indicator of forest biomass and structure, yet accurate mapping across the Amazon remains challenging. Here, we generated a canopy height map of the Amazon forest at ~4.8 m resolution using Planet NICFI imagery and a deep learning U‐Net model trained with airborne LiDAR data.

Evaluation of the cool-down behaviour of ITER FW beryllium tiles for an early failure detection

open access: yesNuclear Materials and Energy, 2016
The design of the first wall in ITER foresees several hundred thousand beryllium tiles, which are bonded to the water-cooled CuCrZr supporting structure. Due to the nature of a Tokamak reactor this bonding is faced to thermal fatigue.

Deep learning‐based ecological analysis of camera trap images is impacted by training data quality and quantity

open access: yesRemote Sensing in Ecology and Conservation, EarlyView.
Machine learning image classifiers are increasingly being used to automate camera trap image labelling, but we don't know how much ML model accuracy matters for downstream ecological analyses. Using two large data sets from an African savannah and an Asian dry forest ecosystem, we compared human labelled data with predictions from deep‐learning models ...
