[2]MEMS Research Unit, Fondazione Bruno Kessler, Povo di Trento, Italy

We present an easy-to-use toolbox for the automated generation of reduced-order mixed-level models for the evaluation of squeeze-film damping in microelectromechanical systems. The toolbox is programmed in JAVA and heavily exploits the functionality provided by the COMSOL API. The ... En savoir plus

Constraints on Ocean Floor Permeability from Hydrothermal Modelling

S. Titarenko[1], A. McCaig[1]
[1]School of Earth and Environment, University of Leeds, Leeds, UK

The Atlantis massif is a domal submarine seamount close to the mid-Atlantic Ridge at 30 °N. Close to the crest of the Massif, the Lost City hydrothermal field (LCHF) has been active for at least 120,000 years, venting fluids with a temperature of 40-90 °C. 5 km north of Lost City, a ...
