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.

Characteristics of individuals who make impulsive suicide attempts [PDF]

open access: yesJournal of Affective Disorders, 2012
Previous research has identified only a few variables that have been associated with making an impulsive suicide attempt. The aim of the current study was to compare individuals who made an impulsive suicide attempt with those who made a premeditated attempt on both previously examined and novel characteristics.Participants were classified as making an

Electrical Tree Initiation Properties in Cross-Linked Polyethylene Under DC-Impulse Composite Voltages

open access: yesIEEE Access, 2018
DC cables may be subjected to impulse overvoltage during operation, which may cause electrical tree inside the cable insulation. So, it is necessary to investigate the influence of impulse voltage on the insulation of dc cable.
