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…
Early warning signals for critical transitions in complex systems
Sandip V. George, Sneha Kachhara, G. Ambika
In this topical review, we present a brief overview of the different methods and measures to detect the occurrence of critical transitions in complex systems. We start by introduci…
Multiplex Recurrence Networks from multi-lead ECG data
Sneha Kachhara, G. Ambika
We present an integrated approach to analyse the multi-lead ECG data using the frame work of multiplex recurrence networks (MRNs). We explore how their intralayer and interlayer to…
Quantifying information loss on chaotic attractors through recurrence networks
K. P. Harikrishnan, R. Misra, G. Ambika
We propose an entropy measure for the analysis of chaotic attractors through recurrence networks which are un-weighted and un-directed complex networks constructed from time series…
Loss of transmission on directed networks due to link deletion
G. Kashyap, G. Ambika
We investigate the effects of link deletion on a 1 - to - 1 transmission process occurring on various models of directed networks and characterize them in terms of the fraction of…
Link deletion in directed complex networks
G. Kashyap, G. Ambika
We present a systematic and detailed study of the robustness of directed networks under random and targeted removal of links. We work with a set of network models of random and sca…
