Parameter estimation in spatially extended systems: The Karhunen-Loeve and Galerkin multiple shooting approach
Anandamohan Ghosh, V. Ravi Kumar, B. D. Kulkarni
Parameter estimation for spatiotemporal dynamics for coupled map lattices and continuous time domain systems is shown using a combination of multiple shooting, Karhunen-Loeve decom…
Simple Denoising Algorithm Using Wavelet Transform
Manojit Roy, V. Ravi Kumar, B. D. Kulkarni +3
We have presented a new and alternative algorithm for noise reduction using the methods of discrete wavelet transform and numerical differentiation of the data. In our method the t…
A simple denoising algorithm using wavelet transform
Manojit Roy, V. Ravi Kumar, B. D. Kulkarni +3
Submission withdrawn because the authors erroneously submitted a revised version as a new submission, see nlin.CD/0002028.
Synchronization and Control of Spatiotemporal Chaos using Time-Series Data from Local Regions
Nita Parekh, V. Ravi Kumar, B. D. Kulkarni
In this paper we show that the analysis of the dynamics in localized regions, i.e., sub-systems can be used to characterize the chaotic dynamics and the synchronization ability of…
Analysis and Characterization of Complex Spatio-temporal Patterns in Nonlinear Reaction-Diffusion Systems
Nita Parekh, V. Ravi Kumar, B. D. Kulkarni
Two important classes of spatio-temporal patterns, namely, spatio-temporal chaos and self-replicating patterns, for a representative three variable autocatalytic reaction mechanism…
