Associations of Functional and Dysfunctional Impulsivity to Smoking Characteristics [PDF]

open access: yesJournal of Addiction Medicine, 2012
Although the relation between impulsivity and smoking is well-documented, one model of impulsivity that has received little attention in the addiction literature separates impulsivity into 2 dimensions: functional impulsivity (tendency to make quick effective decisions) and dysfunctional impulsivity (tendency to make quick ineffective decisions).This ...

Characteristic impulse-response grammians

open access: yesElectronics Letters, 1991
A new Grammian known as the characteristic impulseresponse Grammian is introduced. It is an extension of the impulse-response Grammian presented by Agathoklis and Srceram. An important property of the characteristic impulse-response Grammian which can be useful in modelreduction application is also derived.
