Power, stability of power, and creativity [PDF]

open access: yesJournal of Experimental Social Psychology, 2011
Power hierarchies are an essential aspect of social organization, create stability and social order, and provide individuals with incentives to climb the hierarchical ladder. Extending previous work on power and creativity, we put forward that this relationship critically depends on both the stability of the power hierarchy and the relevance of ...

Global stability analysis and stabilization of power amplifiers [PDF]

open access: yes2008 Microwaves, Radar and Remote Sensing Symposium, 2008
Power amplifiers often exhibit undesired behavior from certain input power value which cannot be predicted with a small-signal stability analysis. Among the commonly observed undesired phenomena are spurious oscillations, frequency divisions, hysteresis or chaos.
