A mixed-platform framework for Dynamic Stability Assessment

Maher Kayal, Georgios Lilis, Laurent Fabre, Theodoros Kyriakidis, Guillaume Olivier Lanz, Denis Sallin

This paper describes a mixed-platform framework dedicated to Dynamic Stability Assessment of power systems. DSA refers to tools capable of characterizing the dynamic stability of the system. Time domain simulation is critical for DSA analysis and is done b ...

Experimental Analysis of Lag Sources in Pinned Photodiodes

Maher Kayal, Nicolas Blanc, Lysandre-Edouard Bonjour

A measurement method is reported to distinguish the different mechanisms that lead to image lag in image sensors based on pinned photodiodes (PPDs). This new method can differentiate between the lag caused by a potential barrier or pocket and gate traps in ...
