Tracking Dynamical Transitions using Link Density of Recurrence Networks
Rinku Jacob, R. Misra, K P Harikrishnan +1
We present Link Density (LD) computed from the Recurrence Network (RN) of a time series data as an effective measure that can detect dynamical transitions in a system. We illustrat…
Multifractal and recurrence measures from meteorological data of climate zones in India
Joshin John Bejoy, Jayesh Dave, G. Ambika
We present a study on the spatio-temporal pattern underlying the climate dynamics in various locations spread over India, including the Himalayan region, coastal region, central an…
Recurrence measures and transitions in stock market dynamics
Krishnadas M., K. P. Harikrishnan, G. Ambika
The financial markets are understood as complex dynamical systems whose dynamics is analysed mostly using nonstationary and brief data sets that usually come from stock markets. Fo…
Explosive synchronization in coupled nonlinear oscillators on multiplex network
Umesh Kumar Verma, G. Ambika
We report the emergence of explosive synchronization in a multiplex network where oscillators on the first layer are coupled with attractive coupling and those on the second layer,…
Structure and Stability of the Indian Power Transmission Network
Vedang Tamhane, G. Ambika
We present the study on the Indian power transmission network using the framework of a complex network and quantify its structural properties. For this, we build the network struct…
Evidence for dynamical changes in Betelgeuse using multi-wavelength data
Sneha Kachhara, Sandip V. George, Ranjeev Misra +1
The reasons behind the Great Dimming and subsequent rising in the brightness of Betelgeuse between October 2019 and March 2020 still continue to baffle astronomers. It has been sho…
