Interactive Visualization of Diode Physics: Bridging the Fidelity‐Accessibility Gap in Web‐Based Engineering Education

Computer Applications in Engineering Education, Volume 34, Issue 3, May 2026.
ABSTRACT In engineering education, a “fidelity‐accessibility trade‐off” persists: accessible web simulations often lack physical accuracy, while complex industrial tools impose heavy cognitive loads. This hinders effective instruction in semiconductor physics in remote, hardware‐constrained environments.

Identifying Oscillation‐Vulnerable Buses Using Impedance‐Based Reflection Coefficient

Electronics Letters, Volume 62, Issue 1, January/December 2026.
We propose a method to identify oscillation‐vulnerable buses by applying the Barkhausen criterion to an impedance‐based reflection‐coefficient analysis in power systems. The method computes the reflection‐coefficient magnitude and phase from the Thevenin impedance seen from each bus and the corresponding load impedance, and evaluates phase variations ...
