Dynamic Magnetostriction of CoFe2O4 and Its Role in Magnetoelectric Composites

Applications of magnetostrictive materials commonly involve the use of the dynamic deformation, i.e., the piezomagnetic effect. Usually, this effect is described by the strain derivative ∂λ=∂H, which is deduced from the quasistatic magnetostrictive…

Robust distributed calibration of radio interferometers with direction dependent distortions

In radio astronomy, accurate calibration is of crucial importance for the new generation of radio inter-ferometers. More specifically, because of the potential presence of outliers which affect the measured data, robustness needs to be ensured. On…

Influence of the temporal resolution of the water consumption profile on photovoltaic water pumping systems modelling and sizing

Photovoltaic water pumping could significantly improve water access, particularly in off-grid rural villages of Sub-Saharan Africa. Earlier, we have developed and validated a numerical model of a photovoltaic water pumping system (PVWPS). Such model…

Bayesian calibration using different prior distributions: an iterative maximum a posteriori approach for radio interferometers

In this paper, we aim to design robust estimation techniques based on the compound-Gaussian (CG) process and adapted for calibration of radio interferometers. The motivation beyond this is due to the presence of outliers leading to an unrealistic…
