Multi-Step Ahead Ex-Ante Forecasting of Air Pollutants Using Machine Learning
Mathematics, 2023 In this study, a novel general multi-step ahead strategy is developed for forecasting time series of air pollutants. The values of the predictors at future moments are gathered from official weather forecast sites as independent ex-ante data.

International Journal of Electrical Power & Energy Systems, 2019 This paper presents a method for detecting series arcing faults in AC home electrical networks. The proposed algorithm is based on both a Kalman filter, used for identifying fault symptoms and a decision block, which confirms the presence of a series arc

Parameters affecting the arcing time of HVDC circuit breakers using black box arc model
IET Generation, Transmission & Distribution, 2019 Arc interruption of high voltage direct current (HVDC) circuit breakers (CBs) is one of the main challenging factors for using HVDC grids. To evaluate the arc interrupting capability in HVDC CBs, black box arc models are used to represent the nonlinear ...
