Abstract: In Li-ion battery applications, effective energy management relies heavily on accurate knowledge of the state of charge (SOC). As SOC cannot be directly measured, it must be estimated using ...

Reporters Without Borders (RSF) and partner organisations have filed a lawsuit against the Brazilian state denouncing the use ...

Abstract: This paper introduces a novel sliding mode control (SMC) design utilizing a Proportional-Integral-Derivative (PID) Sliding Surface (SS) for frequency regulation in multi-area electrical ...

Can light behave like a whirlwind? It turns out it can—and such "optical tornadoes" have now been created in an extremely small structure by scientists from the Faculty of Physics at the University of ...

From skyscrapers to massive bridges, I-beams help engineers build stronger structures with less material. Their distinctive shape is designed to handle bending loads as efficiently as possible.
