[Other] Mathematical-modeling1 DL : 0: In this article we investigate possible scenarios of pattern formations in reaction-diffusion systems with time fractional derivatives. Linear stability analysis is performed for different values of derivative orders. Results of qualitative analysis are confirmed by numerical simulations of specific partial differential equations. Most attention is paid to two models: a fractional order reaction diffusion system with Bonhoeffer van der Pol kinetics and to the Brusselator model.

[Other] Load-frequency-control-problem-in-interconnected- DL : 0: Abstract In this paper, a robust Fractional Order PI D controller that contains an integral frac- tion action and a simple ﬁ ltered derivative action, is investigated on Automatic Generation Control (AGC) of a three areas reheat-thermal system. For more realistic study some nonlinear constraints have been introduced such as Governor Dead Band (GDB), Generation Rate Constraints (GRC) and boiler dynamics. The optimal controller parameters are tuned through new evolutionary algo-
