Numerical simulation of a collapsing bubble subject to gravity

Mohamed Farhat, Outi Supponen

The present paper focuses on the simulation of the expansion and aspherical collapse of a laser-generated bubble subjected to an acceleration field and comparison of the results with instances from high-speed videos. The interaction of the liquid and gas i ...

Entrainment,motion, and deposition of coarse particles transported by water over a sloping mobile bed

Christophe Ancey, Joris Heyman

In gravel bed rivers, bed load transport exhibits considerable variability in time and space. Recently, stochastic bed load transport theories have been developed to address the mechanisms and effects of bed load transport fluctuations. Stochastic models i ...

Shortening design time through multiplatform simulations with a portable OpenCL golden-model: the LDPC decoder case

Andreas Peter Burg, Paolo Ienne, Georgios Karakonstantis, David Novo Bruna, Gabriel Falcao Paiva Fernandes, Madhura Purnaprajna

Hardware designers and engineers typically need to explore a multi-parametric design space in order to ﬁnd the best conﬁguration for their designs using simulations that can take weeks to months to complete. For example, designers of special purpose chips ...

Collision-Free Intersection Crossing of Mobile Robots Using Decentralized Navigation Functions on Predefined Paths

Denis Gillet, Laleh Makarem, Benjamin Fankhauser

This paper deals with the coordination of a group of mobile robots at an intersection. It focusses on decentralized navigation functions (DNFs) to achieve efficient traffic control. The main challenge is to define virtual potentials, which are used by dece ...
