Efficiency Optimisation of Slotless Magnetic Bearing Machines

Yves Perriard, Douglas Martins Araujo, Leopoldo Rossini, Guzmán Borque Gallego

Efficiency is one of the key performance indexes in the design of electric motors. When considering fully active magnetic bearing machines, this aspect gain further relevance due to the necessity of actively controlling all the remaining degrees of freedom ...

An inverse optimization approach to understand human acquisition of kinematic coordination in bimanual fine manipulation tasks

Aude Billard, Kunpeng Yao

Tasks that require the cooperation of both hands and arms are common in human everyday life. Coordination helps to synchronize in space and temporally motion of the upper limbs. In fine bimanual tasks, coordination enables also to achieve higher degrees of ...

A Magnetic Continuum Device with Variable Stiffness for Minimally Invasive Surgery

Dario Floreano, Alice Tonazzini

One of the challenges of minimally invasive surgery is the dexterous manipulation and precise control of small diameter continuum surgical instruments. In this paper, a magnetic continuum device with variable stiffness (VS) is presented, whose tip can be p ...

Towards Modelling of Visual Saliency in Point Clouds for Immersive Applications

Touradj Ebrahimi, Evangelos Alexiou, Peisen Xu

Modelling human visual attention is of great importance in the field of computer vision and has been widely explored for 3D imaging. Yet, in the absence of ground truth data, it is unclear whether such predictions are in alignment with the actual human vie ...

Mineral equilibria and thermodynamic uncertainties in the geothermometrical characterisation of carbonate geothermal systems of low temperature. The case of the Alhama-Jaraba system (Spain)

Geothermometrical characterisation of low-temperature, carbonate-evaporitic geothermal systems is usually hampered by the lack of appropriate mineral equilibria to successfully use most of the classical geothermometers and/or by the thermodynamic uncertain ...

Bidirectional interactions facilitate the integration of a robot into a shoal of zebrafish Danio rerio

Francesco Mondada, Frank Bonnet, Vaios Papaspyros, Bertrand Eric Collignon

Many studies on collective animal behavior seek to identify the individual rules that underlie collective patterns. However, it was not until the recent advancements of micro-electronic and embedded systems that scientists were able to create mixed groups ...

How employment constrains participation in MOOCs?

Pierre Dillenbourg, Lukasz Kidzinski, Mina Shirvani Boroujeni

Massive Open Online Courses (MOOCs) changed the way continuous education is perceived. Employees willing to progress their careers can take high quality courses. Students can develop skills outside curriculum. Studies show that most of the MOOC users are p ...

Influence of visco-elasticity on the stress development induced by alkali-silica reaction

Karen Scrivener, Cyrille Dunant, Alain Benjamin Giorla

The alkali-silica reaction causes long-term degradation in the microstructure of affected concrete as well as macroscopic expansion. In this paper, a micro-mechanical model based upon an explicit representation of the microstructure has been used to simula ...
