Tracking an Underwater Target with Unknown Measurement Noise Statistics Using Variational Bayesian Filters

no code implementations15 May 2023 Shreya Das, Kundan Kumar, Shovan Bhaumik

Both adaptive filtering techniques are implemented using the traditional Gaussian approximate filters and are applied to a bearings-only tracking problem illustrated with moderately nonlinear and highly nonlinear scenarios to track a target following a nearly straight line path.

Occupant's Behavior and Emotion Based Indoor Environment's Illumination Regulation

no code implementations19 Feb 2023 Shreya Das

Deep learning is used for emotion detection using several optimizers out of which Adadelta gave the maximum blind test accuracy for multi-class classification.

Resolving Left-Right Ambiguity During Bearing Only Tracking of an Underwater Target Using Towed Array

no code implementations3 Feb 2023 Shreya Das, Ranjeet Kumar Tiwari, Shovan Bhaumik

In bearing only tracking using a towed array, the array can sense the bearing angle of the target but is unable to differentiate whether the target is on the left or the right side of the array.

Understanding Magnetism in Double Double Perovskites: A Complex Multiple Magnetic Sublattice System

no code implementations26 Jan 2021 Anita Halder, Shreya Das, Prabuddha Sanyal, Tanusri Saha-Dasgupta

We find that the magnetism in such multiple sublattice compounds is governed by the interplay and delicate balance between two distinct mechanisms, a) kinetic energy-driven multiple sublattice double exchange mechanism and b) the conventional super-exchange mechanism.
