Dynamics of the COVID-19 epidemic in Ireland under mitigation
Background In Ireland and across the European Union the COVID-19 epidemic waves, driven mainly by the emergence of new variants of the SARS-CoV-2 have continued their course, despite various interventions from governments.

Adaptive myriad filter with time-varying noise- and signal-dependent parameters
The research subject of this article is the methods of locally adaptive filtering of non-stationary signals. The goal is to develop a locally-adaptive algorithm for non-stationary noise (from the viewpoint of its time-varying variance) suppression in ...

Estimating time-varying treatment effects in longitudinal studies
Longitudinal study designs are frequently used to investigate the effects of a naturally observed predictor (treatment) on an outcome over time. Because the treatment at each time point or wave is not randomly assigned, valid inferences of its causal ...

Stability analysis of fractional-order systems with randomly time-varying parameters
This paper is concerned with the stability of fractional-order systems with randomly timevarying parameters. Two approaches are provided to check the stability of such systems in mean sense. The first approach is based on suitable Lyapunov functionals to

Prediction of Modal Parameters of Linear Time-Varying Systems
Many engineering structures, such as cranes, traffic-excited bridges, flexible mechanisms and robotic devices exhibit characteristics that vary with time and are referred to as time-varying or nonstationary.

GPI-repetitive control for linear systems with parameter uncertainty / variation
Robust repetitive control problems for uncertain linear systems have been considered by different approaches. This article proposes the use of Repetitive Control and Generalized Proportional Integral (GPI) Control in a complementary fashion.
