in this paper, construction rules of the root locus of a positive feedback system whose loop transfer function is not strictly proper have been investigated. the root locus method is being used since 1950. it is demonstrated that some of the steps in this technique are not general and for a positive feedback system whose loop transfer function is not strictly proper are not valid. to overcome t...

due to the changes which may occur in their parameters, systems are usually demonstrated by some subsystems for different conditions. this paper employs modified petri nets (mpn) to model theses subsystems and makes it simple to analyze them. in this method, first, the continuous transfer function is converted to a discrete transfer function and then, by mpn, system is modeled and analyzed. all...

I analyze the way in which Bildungsroman seizes on bisexuality two contemporary French novels: Saccage (2006) by Éric Jourdan and A Boy Like Another (2012) Joël Breurec. novelistic genre representing entry into adulthood of a young protagonist his identity construction, proves here to be an adequate analytical tool for understanding construction bisexual through literary strategies aimed at rep...
