Flexoelectrically Induced Polar Topology in Twisted SrTiO3 Membranes

open access: yesAdvanced Materials, EarlyView.
Twisted SrTiO3 bilayers host polar vortices of flexoelectric origin, revealed through combined experiment and theory. By reconstructing polarization from the toroidal moment of strain gradients, the work establishes a 3D chiral state with broken inversion and mirror symmetries.

Object tracking by supported particles

2014 11th International Conference on Ubiquitous Robots and Ambient Intelligence (URAI), 2014
Object tracking is still remains as a challenge to the computer vision community. Several methods have been proposed until now to track. One renowned method to track is particle filter, a probabilistic model that predicts object position based on recursive Bays formula.

Particle Tracks and Fission Tracks

1992
A fast charged particle, when passing through an insulating solid, creates a narrow trail of damage along its trajectory. This damage trail persists in the solid after the particle has come to rest and is called a charged particle track or nuclear track. The solid in which the tracks are registered is commonly called the detector.

Wake tracking with particle filter

2013 21st Signal Processing and Communications Applications Conference (SIU), 2013
In the scope of underwater warfare, signature of ship wakes is attractive for its exploitation in ship detection, tracking and classification. Ship wake signature is generally more distinct than the signature of the ship. In this work, particle filter method has been simulated for target tracking using wake echo measurements.

Touch tracking with a particle filter

Machine Vision and Applications, 2013
We report on a system for multi-touch tracking from linescan cameras using particle filters. We show that a particle filter incorporating a local search element is almost as accurate as an exhaustive search algorithm and is significantly faster as the number of touches increases. The system achieves over 95 % correct tracking with an error tolerance of
