Thin silicate platelets in a dimension of approximately 80 x 80 x 1 nm(3) are isolated for the first time by a newly developed process involving one-step exfoliation of natural montmorillonite clay and toluene/aqueous NaOH extraction. The platelets are observed to be polygon shape by transmission electron microscopy (TEM) and round bent-leaf shape by(More)
In this paper, we discuss the problem of adaptive control of autonomous switched systems. Classical adaptive control for continuous systems has properties such as bounded signals and or convergence of the output error. Here, we derive similar results for switched systems with adaptive control using stability theory of switched systems. Zero output tracking(More)
In this paper, we propose a supervisory controller for the discrete model of a heating, ventilating and air conditioning (HVAC) system and then design the nonlinear controller for the heating and cooling subsystems within. The HVAC system includes the discrete event dynamics and nonlinear continuous dynamics, both are very complex and challenging. Here we(More)
