Control of Level Set Methods

Level Set Methods (S. Osher, J. Sethian, J. of Computational Physics 1987) are a class of very popular methods to propagate interfaces. Our aim is to develop methodologies to control in time  fronts described by Level Set Methods. A project "C-LEVEL” was funded by US AFOSR, Air Force Office of Scientific Research. 

Development of algorithms and a scheduling dynamic system for managing drone swarms

M.A.R.S. is a patented platform developed by Inspire (Unige spin-off) that allows:

-  integrated logistic for drones deployment
– extended flight missions enabled by automatic battery replacement system
– fractionable payload management system
– collaborative drones flight in swarm configuration

Drone Swarms in Fire Suppression Activities

Recent huge technological development of Unmanned Aerial Vehicles (UAVs) can provide breakthrough means of fighting wildland fires. We have studied an innovative forest firefighting system based on the use of a swarm of hundreds of UAVs able to generate a continuous flow of ex-tinguishing liquid on the fire front, simulating rain effect. Automatic battery replacement and re-filling of the extinguishing liquid ensure the continuity of the action.

Wound healing in Drosophila pupae

We study wound healing in collaboration with L. Neves de Almeida (Sorbonne Université) and with A. Jacinto, a biologist of the Lisboa University. We proposed continuous mathematical models where the wound is described by Level set methods. Currently, we are modeling a complex mechanism starting in the first minutes of wound healing.

Dynamic Mode Decomposition for fluid flows

The spatial and time behavior of fluid flows at different Reynolds numbers and stream turbulence intensity levels is analysed by combining dynamic mode decomposition and
moving horizon estimation in order to detect regime transitions. The norm of the residuals  in processing successive snapshots of the flow
velocity field shows a trend that is used to identify the change from stable and unstable
regimes.
