Highlights of the Year

  • In collaboration with the Bordeaux cancer therapy of Bordeaux (Bergonie) the MC2 team has developped an adaptive radiotherapy technique to follow automatically organs using the low resolution control scanners. This method is helpful in order to avoid the overdose in high risk organs. Thanks to image processing it was shown that the movement of organs is much more important than predicted before and a better control is necessary. This work continues with the design of automatic tools to follow organ movements.

  • In collaboration with Rajat Mittal (John Hopkins) accurate numerical simulations were performed using the NaSCar code to improve the energetic efficiency of underwater submarine robots. As these robots are propelled in the water using fish like models, the used flippers were modified maximizing their energy and therefore minimizing their energy consumption.

  • As the final step of the PREDIT Caravaje, the optimized form of an actuator was designed using adjoint methods. It should be implemented in a car body in order to reduce drag forces and consequently the fuel consumption/pollution. The results are published.

  • Numerical simulations were performed to reproduce the soap bubbles experiments performed by Hamid Kellay team (Loma). Simulations are allowed by a change of metrics between a plane and an hemisphere using a stereographic projection. The results in accordance with the experiments were published in Nature scientific reports.
