2007-2008: Chaos - book
This is work I had done with Dr. Predrag Cvitanovic, Domenico Lippolis and Jonathan Halcrow. It concerns the design of a low-dimensional Poincare section for highly contracting flows based on mappings of the unstable manifold. The curvature of the unstable manifold allows us to track the stretch and fold dynamics of chaos in Rossler flow as an example. Symbolic dynamics is used to predict cycles and the markov partitioning. The effect of noise in limiting the accuracy in resolvng state space is also considered.
This work is available online here The MATLAB code used and the generated figures are also available in the archives linked to this page: http://www.cns.gatech.edu/ChaosBook/projects/index.shtml.
This stuff is used in Predrag's book about chaos: "Chaos: Classical and Quantum" available at http://chaosbook.org/
2005: M. Tech Thesis
My M.Tech thesis submitted to IIT Kharagpur and completed under the supervision of Dr. A.S. Dhar and Dr. N.B. Chakrabarti concerned the development of analog vlsi techniques for video processing and transmission. Also I had worked on pulse generators for UWB applications. The thesis is available here
2004 : B. Tech Thesis
My B. Tech thesis also under the supervision of Dr. A. S. Dhar was concerned with optimising power dissipation in the OTA used for switched capacitor filter design. I also worked on developing switched capacitor techniques to implement DCT and DST efficiently. A copy of the thesis is here
