An Extension of the Invariance Principle for Switched Affine System

Trends in Computational and Applied Mathematics, 2020
In this paper, an approach to investigate switched affine system via matrix inequalities is presented. Particularly, an extension of LaSalle’s invariance principle for this class of systems under arbitrary dwell-time switching signal is presented.

Design of large aperture sparse array for mainlobe interference cancellation

The Journal of Engineering, 2019
Large aperture sparse array has the ability of mainlobe interference suppression. However, sparse array causes grating lobe problem. If the array is steering at the target and the mainlobe interference is located at the grating lobe, the adaptive filter ...

Potential of auxiliary strobe lights on train locomotives to improve level crossing safety [PDF]

, 2022
Inattentiveness of road users on approach to passive railway crossings represents a major threat to level crossing safety. An auxiliary strobe light system installed on trains in addition to existing headlights may help address this issue by providing an
