Tutorial on Self-Organization
Duration: 3-4 hours
Conducted by: Prof. R. P. Sharma, IIT Delhi
Prof. R .P. Sharma has his Masters from Meerut University, Meerut and Ph.D. from Indian Institute of Technology Delhi. He is working on Electromagnetic field computations both analytically and numerically, nonlinear dynamical systems, self-organization and fractals.
Specifically, these studies are carried out with an emphasis on high power laser and matter interactions for laser induced fusion energy and particle acceleration, plasma-sheath resonance in plasma reactors for plasma processing, electromagnetic hazards (like mobile phone human head interaction), Magneto hydrodynamic systems for MHD power generation, space applications for solar coronal heating, solar wind turbulence and generation of solar energetic particles, stability of power systems and self-organization.
He has guided 14 Ph.D. students, published over 120 research papers in the journals of international repute and completed several sponsored projects with outstanding rating.
He was awarded Alexander von Humboldt fellowship, Max Plank fellowship and European Commission fellowship. He was also a visiting professor at the University of Alberta Edmonton (Canada), University of Bradford (U.K.) and short term visitor at various reputed research groups.
Tutorial Details:
Self-Organizing dynamical systems play a very important role in Science and Technology. Including the study of bifurcation processes, fixed points, attractors, fractals and calculation of fractal dimensions, chaos, to cite a few examples, it has found wide applications. Because of its all pervasiveness, this is emerging as a new field in itself. It has been found that the distribution of stars and galaxies in our universe is multifractal, i.e. self-similar, and there is even evidence of multifractals in the stock markets and heartbeat rythms. The subject hence has found its importance in the real-world problems from a broad range of disciplines including population dynamics, biology, economics, nonlinear optics and neural networks.
This tutorial summarizes the importance of nonlinear effects in electromagnetic field computation with examples and their applications to introduce the concept of self-organization. Special emphasis will be given to the applications in the field of communication where we consider ionospheric (space weather), optical and mobile communication by starting from historical examples and progressing to present day techniques. Population dynamics model shall be introduced in detail. Recent research results in the field of possible bio effects of mobile communication will also be presented.
The science of self organization with an emphasis on high power laser and matter interactions for laser induced fusion energy and particle acceleration, electromagnetic hazards (like mobile phone human head interaction), Magneto hydrodynamic systems for MHD power generation, space applications for solar coronal heating, solar wind turbulence and generation of solar energetic particles will also be considered.
