Modelling the urban microclimate and its impact on the energy demand of buildings and building clusters

The urban microclimate (UMC) can strongly affect the building energy demand. In this paper, the impact of the UMC on the space heating and cooling energy demand of buildings is analysed for typical office buildings in street canyon configurations, using de ...

EBSD coupled to SEM in situ annealing for assessing recrystallization and grain growth mechanisms in pure tantalum

Roland Logé

An in situ annealing stage has been developed in-house and integrated in the chamber of a Scanning Electron Microscope equipped with an Electron BackScattered Diffraction system. Based on the Joule effect, this device can reach the temperature of 1200°C at ...

Power requirements for electron cyclotron current drive and ion cyclotron resonance heating for sawtooth control in ITER

Olivier Sauter, Stefano Coda, Timothy Goodman, Jonathan Graves, Costanza Zucca, Martin Jucker, Otto Asunta

13 MW of electron cyclotron current drive (ECCD) power deposited inside the q = 1 surface is likely to reduce the sawtooth period in ITER baseline scenario below the level empirically predicted to trigger neoclassical tearing modes (NTMs). However, since t ...

Modelling the Urban Microclimate and its Influence on Building Energy Demands of an Urban Neighbourhood

Jérôme Henri Kämpf

In the past decades the portion of the population living in urban areas has continuously increased. Due to the high building density, the microclimate in urban areas changed significantly compared to rural areas. The temperatures measured in urban areas ar ...

Dissipation as variable in cartilage mechanobiology

Philippe Abdel Sayed

Mechanobiology is the analysis of the role of mechanical forces in educing a molecular response in cells. Nowadays, mechanobiology may contribute to clinical progress. In particular, mechanical stimulation has been proposed to induce chondrogenesis in engi ...

Heat Exchanger Anchors for Thermo-active Tunnels

Lyesse Laloui, Fabrice Dupray, Thomas Mimouni, Sophie Minon

Shallow geothermal power represents an important energy resource for the heating and cooling of the buildings. Due to relatively low temperature levels encountered at shallow depths in the soil, between 10°C and 20°C, heat pumps are required to process the ...

Characterization method of dielectric properties of free falling drops in a microwave processing cavity and its application in microwave internal gelation

Manuel Alexandre Pouchon, Sébastien Vaucher, Cédric Cozzo

Microwave internal gelation (MIG) is a chemical process proposed for the production of nuclear particle fuel. The internal gelation reaction is triggered by a temperature increase of aqueous droplets falling by gravity by means of non-contact microwave hea ...

Imaging of molybdenum erosion and thermography at visible wavelengths in Alcator C-Mod ICRH and LHCD discharges

Christian Gabriel Theiler

We describe results from imaging observations of atomic line and continuum emission in the 550.6 nm region on Alcator C-Mod. Both the 550.6 nm neutral molybdenum emission and the adjacent 549 nm continuum emission are imaged separately to isolate line emis ...

Dye sensitised solar cells with nickel oxide photocathodes prepared via scalable microwave sintering

Ulf Anders Hagfeldt, Muhammad Awais

Photoactive NiO electrodes for cathodic dye-sensitized solar cells (p-DSCs) have been prepd. with thicknesses ranging between 0.4 and 3.0 μm by spray-depositing pre-formed NiO nanoparticles on fluorine-doped tin oxide coated glass substrates. The larger th ...

Stability of a Stochastic Model for Demand-Response

Jean-Yves Le Boudec, Dan-Cristian Tomozei

We study the stability of a Markovian model of electricity production and consumption that incorporates production volatility due to renewables and uncertainty about actual demand versus planned production. We assume that the energy producer targets a fixe ...
