How do peripheral and relatively isolated regions innovate? Recent research has tended to stress the importance of agglomeration economies and geographical proximity as key motors of innovation. According to this research, large core areas have significant advantages with respect to peripheral areas in innovation potential. Yet, despite these trends, some remote areas of the periphery are remar...

By introducing Colpitts oscillator as a chaotic system, this paper deals with back-stepping control method and investigates the restrictions and problems of the controller where non-existence of a suitable response in the presence of uncertainty is the most important problem to note. In this paper, the back-stepping sliding mode method is introduced as a robust method for controlling nonlinear ...
