Atmospheric Electricity, Geological Heterogeneity and Hydrogeological Processes

open access: yesProceedings, 2017
Elements of surface atmospheric electricity have never been used to solve problems of applied geophysics. A physical model representation of hydrogen, methane, radon, and elements of surface atmospheric electricity is constructed.

Heat Transfer Challenges for MVDC Power Cables Used in Wide Body All Electric Aircraft Under Low Pressures

open access: yesIEEE Access, 2022
Power cables are a vital component of the future electric power systems (EPS) envisaged in wide body all electric aircraft (AEA). They are required to be high power delivery and low system mass.

Atmospheric Electric Field Data Logger System

open access: yesJurnal Teknologi, 2013
Weather can  be unpredictable as there are a lot of uncertainties in predicting thunderstorms. Most of our navigation systems, including those on air, land and water, as well as broadcasting systems, are directly affected by the weather on a daily basis.

A Thunderstorm Cloud Point Charge Localization Method Based on CEEMDAN and SG Filtering

open access: yesIEEE Access, 2021
The current thunderstorm monitoring methods ignore the nonlinear and non-stationary characteristics of atmospheric electric field signals, which has a negative effect on the monitoring results. Based on complementary ensemble empirical mode decomposition
