Título: Collaborative SLAM for real-time indoor/outdoor geolocalization

Resumen: Real-time simultaneous localization and mapping has been extensively studied in the robotics and computer vision fields for performing tasks ranging from augmented reality applications to autonomous vehicles. Nowadays, SLAM systems have been combined with GPS sensors in order to increase the accuracy of geolocalization. The collaboration between sensors allows to maintain a valid tracking even at indoor environments where the GPS sensor is absent or partially available. In this presentation, two systems will be presented. The first system is a LiDAR-Visual-Inertial (LVI) system that has been tested under the terms of the MALIN challenge, where it will be shown how such systems can be useful for emergency response agents in highly dynamic environments. The second system, which is a system in progress, uses 360 cameras + Inertial + GPS for performing accurate geolocalization and 3D reconstruction of urban scenarios.

Título: The Geometry of Fluid Dynamics

Resumen: Fluid motion has a remarkable geometric structure generated by Poisson structures on the Hamiltonian and variational structures on the Lagrangian side. I will briefly review the standard results for ideal incompressible homogeneous flows and then show how this is extended to fluids with advected quantities. A much more elaborate extension happens for the Eringen model of liquid crystals because these fluids have internal structure. Then I will introduce a momentum map with values in differential characters that captures topological information, something the classical momentum map cannot do. This has consequences in hydrodynamics, specifically for Clebsch variables, since it permits to deal with solutions whose helicity is integer valued.
