Analysis of lock-exchange gravity currents over smooth and rough beds

Mário Jorge Rodrigues Pereira Da Franca, Claudia Adduce

Gravity currents produced by full-depth lock-release of saline water into a fresh water tank are studied focusing on the influence of the initial density of the saline mixture in the lock and the bed roughness on gravity current kinematics. Temporal evolut ...

Phase Analysis of the Stretching Cycles of the Head of Unsteady Gravity Currents Developing over Smooth and Rough Beds

Mário Jorge Rodrigues Pereira Da Franca, Helena Isabel Dos Santos Nogueira, Claudia Adduce

Gravity currents are buoyancy driven flows occurring spontaneously in nature or resulting from human intervention. Examples of gravity currents in the water are oceanic fronts, resulting from differences in temperature and salinity, and turbidity currents ...

Chengdu University Press2013

The spatial domain of Molecular Dynamics simulations is usually a regular box that be easily divided in subdomains for parallel processing. Recent efforts aimed at simulating complex biological systems, like the blood flow inside arteries, require the exec ...

Eddy current effects on a clinical 7T-68 cm bore scanner

Rolf Gruetter, Tobias Kober, Wietske Van der Zwaag, José Pedro Rebelo Ferreira Marques

Eddy currents induced by switching of magnetic field gradients can lead to distortions in short echo-time spectroscopy or diffusion weighted imaging. In small bore magnets, such as human head-only systems, minimization of eddy current effects is more deman ...

Very high-speed slotless permanent-magnet motors

Pierre-Daniel Pfister

The development of very high-speed motors has evolved fascinatingly in the last few years. Due to their speed, their low weight and their high power density, the need for such motors has recently increased for various different applications. Among them, su ...

Multiscale modelling of urban climate

Adil Rasheed

Climate has a direct impact on cities' energy flows due to the space conditioning (heating, cooling) needs of the buildings accommodated. This impact may be reinforced due to climate change and to the (so called) urban heat island effect. The corresponding ...

Search for nuclear magnetic resonance evidence of spin accumulation

Aurore Rudolf

Developments towards an understanding of the nature of conductance at the interface between two different metallic layers – ferromagnetic and non magnetic – as well as the discovery of giant magnetoresistance have stirred attention from both the scientific ...

YOU ARE FIRED! NONVERBAL ROLE ANALYSIS IN COMPETITIVE MEETINGS

Daniel Gatica-Perez

This paper addresses the problem of social interaction analysis in competitive meetings, using nonverbal cues. For our study, we made use of ”The Apprentice” reality TV show, which features a competition for a real, highly paid corporate job. Our analysis ...

2009

In this paper an innovative manufacturing technology is presented that combines electroforming and CFRP application and thus could be an enabling technology to achieve tuningless lightweight RF passive hardware with complex geometries. In order to demonstr ...

An analytical determination of eddy-current losses in a configuration with a rotating permanent magnet

Yves Perriard, Miroslav Markovic

The paper presents a completely analytical method for determining the eddy currents in a cylindrical configuration. The configuration consists of a cylindrical permanent magnet rotating inside a conducting hollow cylinder (stator). The solution is obtained ...
