Online Learning of Correspondences between Images
Michael Felsberg, Fredrik Larsson, Johan Wiklund +2
We propose a novel method for iterative learning of point correspondences between image sequences. Points moving on surfaces in 3D space are projected into two images. Given a poin…
Drone Detection Using a Low-Power Neuromorphic Virtual Tripwire
Anton Eldeborg Lundin, Rasmus Winzell, Hanna Hamrell +2
Small drones are an increasing threat to both military personnel and civilian infrastructure, making early and automated detection crucial. In this work we develop a system that us…
Occurrence of Non-Stationarity at Earth's Quasi-Perpendicular Bow Shock
Ajay Lotekar, Yuri V. Khotyaintsev, Daniel B. Graham +3
Collisionless shocks can exhibit non-stationary behavior even under steady upstream conditions, forming a complex transition region. Ion phase-space holes, linked to shock self-ref…
Ion Reflection by a Rippled Perpendicular Shock
Yuri V. Khotyaintsev, Daniel B. Graham, Andreas Johlander
We use multi-spacecraft Magnetospheric Multiscale (MMS) observations to investigate electric fields and ion reflection at a non-stationary collisionless perpendicular plasma shock.…
Backstreaming ions at a high Mach number interplanetary shock: Solar Orbiter measurements during the nominal mission phase
Andrew P. Dimmock, Michael Gedalin, Ahmad Lalti +9
Solar Orbiter, a mission developed by the European Space Agency, explores in situ plasma across the inner heliosphere while providing remote-sensing observations of the Sun. Our st…
Two-scale cut-and-projection convergence for quasiperiodic monotone operators
Niklas Wellander, Sebastien Guenneau, Elena Cherkaev
Averaging certain class of quasiperiodic monotone operators can be simplified to the periodic homogenization setting by mapping the original quasiperiodic structure onto a periodic…
