T-S Fuzzy Control of Uncertain Chaotic Vibration by Abdelkrim Boukabou, Noura Mansouri

“…We present in this paper a novel and unified control approach that combines intelligent fuzzy logic methodology with predictive method for controlling chaotic vibration of a class of uncertain chaotic systems. We first introduce prediction into each subsystem of Takagi Sugeno (T-S) fuzzy IF-THEN rules and then present a unified T-S predictive fuzzy model for chaos control. …”

Bootstrap Order Determination for ARMA Models: A Comparison between Different Model Selection Criteria by Livio Fenga

“…The present paper deals with the order selection of models of the class for autoregressive moving average. A novel method—previously designed to enhance the selection capabilities of the Akaike Information Criterion and successfully tested—is now extended to the other three popular selectors commonly used by both theoretical statisticians and practitioners. …”
