Topological Feature Extraction of Scanty Time Series Data: A Data-Driven Approach for Dynamic State Change Detection
B. Rishab Antosh, Sanjit Das, N. Nirmal Thyagu
Complex dynamical systems often undergo transitions from periodic to chaotic behaviour as bifurcation parameters vary, making timely detection of these changes essential. Conventio…
Inertial Particle Dynamics in Traveling Wave Flow
P. Swaathi, Sanjit Das, N. Nirmal Thyagu
The dynamics of inertial particles in fluid flows have been the focus of extensive research due to their relevance in a wide range of industrial and environmental processes. Earlie…
Characterization of dynamical systems with scanty data using Persistent Homology and Machine Learning
Rishab Antosh, Sanjit Das, N. Nirmal Thyagu
Determination of the nature of the dynamical state of a system as a function of its parameters is an important problem in the study of dynamical systems. This problem becomes harde…
Characterizing the complexity of time series network graphs: A simplicial approach
N. Nirmal Thyagu, Nithyanand Rao, Malayaja Chutani +1
We analyze the time series obtained from different dynamical regimes of the logistic map by constructing their equivalent time series (TS) networks, using the visibility algorithm.…
The Simplicial Characterisation of TS networks: Theory and applications
Neelima Gupte, N. Nirmal Thyagu, Malayaja Chutani
We use the visibility algorithm to construct the time series networks obtained from the time series of different dynamical regimes of the logistic map. We define the simplicial cha…
Local analysis of the history dependence in tetrahedra packings
N. Nirmal Thyagu, Max Neudecker, Simon Weis +2
The mechanical properties of a granular sample depend frequently on the way the packing was prepared. However, is not well understood which properties of the packing store this inf…
