Characterizing Periodic Variations of Atomic Frequency Standards via Their Frequency Stability Estimates [PDF]

open access: yesSensors, 2023
The onboard atomic frequency standard (AFS) is a crucial element of Global Navigation Satellite System (GNSS) satellites. However, it is widely accepted that periodic variations can influence the onboard AFS.

Solution estimates and stability tests for nonlinear delay integro-differential equations

open access: yesElectronic Journal of Differential Equations, 2022
In this article, we examine various qualitative features of solutions of a nonlinear delay integro-differential equation. We prove three new theorems which include sufficient conditions on asymptotic stability (AS), integrability, and boundedness of ...

Perceived object stability depends on multisensory estimates of gravity. [PDF]

open access: yesPLoS ONE, 2011
BACKGROUND: How does the brain estimate object stability? Objects fall over when the gravity-projected centre-of-mass lies outside the point or area of support.
