Abstract: There are various operating modes of parallel bipolar multi-terminal DC transmission systems, among which there is an asymmetric condition of unipolar-bipolar hybrid form. In this case, the ...

Using electrochemical impedance spectroscopy (EIS) techniques to help obtain battery working conditions like SOH and SOC.

Learn how to test a transformer: insulation resistance, TTR, winding resistance, polarity, continuity, and dielectric checks.

Recently, within the price range of 100,000 yuan, two 'phenomenal models' have emerged that could potentially turn the small car market around: the newly launched Jihu T1, priced between 62,800 yuan ...

Recently, two potential game-changing "phenomenal models" have emerged in the price range of around 100,000 yuan: the newly launched Arcfox T1, priced at 62,800 to 87,800 yuan, and the MG4, available ...

Due to the electrification megatrend, estimating battery model parameters using impedance data is of great interest, since typically battery model parameters are estimated using time domain data, and ...

Exile Hub is one of Global Voices’ partners in Southeast Asia, emerging in response to the 2021 coup in Myanmar, focusing on empowering journalists and human rights defenders. This edited article is ...

Physics and Python stuff. Most of the videos here are either adapted from class lectures or solving physics problems. I really like to use numerical calculations without all the fancy programming ...

Introduction: This work describes the calibration of a laboratory plasma impedance probe, a diagnostic to accurately measure the plasma density using resonances in the self-impedance spectrum that are ...
