Thanjavur, India

The Tamil University, Thanjavur, in Tamil Nadu, India, was established to provide higher research in the Tamil language and advanced study in allied branches such as linguistics, translation, lexicography, music, drama and manuscriptology. M.Phil and Ph.D programmes were introduced in 1992 for disciplines such as Language, Literature, Translation, and Sculpture.The university has six science departments namely Industries and Earth science, Computer Science, Environmental and Herbal Science, Siddha Medicine, Ancient science and Architecture.The Ocean and Atmospheric science and Technology Cell, an autonomous body supported by the Ministry of Earth science, New Delhi is under the Department of Industries and Earth science.

Chaos theory has a manifold variety of applications in science and engineering. The frequent and irregular reversals of the earth’s magnetic field has motivated a number of research studies involving electrical currents within the earth’s molten core. One of the first such nonlinear models that exhibited the frequent and irregular reversals of the earth’s magnetic field was Rikitake’s two-disk dynamo system (1958). Rikitake two-disk dynamo system is a chaotic system that predated the pioneering work of Lorenz (1963). In this paper, we describe the dynamic equations and qualitative properties of the Rikitae two-disk dynamo chaotic system. We also derive new results for the adaptive control of the Rikitake two-disk dynamo chaotic system. MATLAB plots have been depicted to illustrate the phase portraits of the Rikitake two-disk dynamo chaotic attractor and the global chaos control of the Rikitake two-disk dynamo chaotic systems via adaptive control method. © 2015, Sphinx Knowledge House.

One of the most developed of the modern magnetic fusion concepts is the Tokamak. In respect of their symmetry properties, toroidal magnetically confined plasmas have much in common with the Taylor-Couette flow. This research work analyzes the dynamics of the Tokamak system with symmetric and magnetically confined plasma studied by Arter (2009). Then this work discusses the adaptive control of the Tokamak chaotic system with unknown system parameters. The main result is established using Lyapunov stability theory. MATLAB plots have been shown to illustrate all the main results discussed on the Tokamak chaotic system with symmetric and magnetically confined plasma. © 2015, Sphinx Knowledge House.

In the 1970s, nonlinear oscillations and bifurcations were discovered first by modelling and then by experiments for the autocatalytic Brusselators and the Belousov-Zhabotinsky (BZ) chemical reaction. The autocatalytic chemical reaction phenomenon plays a vital role for the breakdown of the stability of the thermodynamical branch. This research work investigates the dynamics and qualitative properties of the autocatalytic Brusselator chemical reaction. Then this work discusses the adaptive anti-synchronization of the identical Brusselator chemical reaction systems. The main chemical antisynchronization result is established using Lyapunov stability theory. MATLAB plots have been shown to illustrate all the main results discussed in this research work. © 2015, Sphinx Knowledge House. All rights reserved. Source
