MLE of Jointly Constrained Mean-Covariance of Multivariate Normal Distributions
Anupam Kundu, Mohsen Pourahmadi
Estimating the unconstrained mean and covariance matrix is a popular topic in statistics. However, estimation of the parameters of under joint constraints such as $Σμ= μ…
Crossover behaviours exhibited by fluctuations and correlations in a chain of active particles
Prashant Singh, Anupam Kundu
We study motion of tagged particles in a harmonic chain of active particles. We consider three models of active particle dynamics - run and tumble particle, active Ornstein-Uhlenbe…
Resetting with stochastic return through linear confining potential
Deepak Gupta, Arnab Pal, Anupam Kundu
We consider motion of an overdamped Brownian particle subject to stochastic resetting in one dimension. In contrast to the usual setting where the particle is instantaneously reset…
Local time for run and tumble particle
Prashant Singh, Anupam Kundu
We investigate the local time statistics for a run and tumble particle in an one dimensional inhomogeneous medium. The inhomogeneity is introduced by considering the po…
Local time of an Ornstein-Uhlenbeck particle
G. Kishore, Anupam Kundu
In this paper, we study the local time spent by an Ornstein-Uhlenbeck particle at some location till time t. Using the Feynman-Kac formalism, the computation of the moment generati…
Computational Modeling and Analysis of Flow-induced Vibration of an Elastic Splitter Plate Using a Sharp-interface Immersed Boundary Method
Anup Kundu, Atul K. Soti, Hemanshul Garg +2
We present the development and benchmarking of an in-house fluid-structure interaction (FSI) solver. An implicit partitioned approach is utilized to couple a sharp-interface immers…
