IMUOptimize: A Data-Driven Approach to Optimal IMU Placement for Human Pose Estimation with Transformer Architecture

no code implementations14 Feb 2024 Varun Ramani, Hossein Khayami, Yang Bai, Nakul Garg, Nirupam Roy

This paper presents a novel approach for predicting human poses using IMU data, diverging from previous studies such as DIP-IMU, IMUPoser, and TransPose, which use up to 6 IMUs in conjunction with bidirectional RNNs.

Simultaneously Learning Speaker's Direction and Head Orientation from Binaural Recordings

no code implementations26 Sep 2023 Harshvardhan Takawale, Nirupam Roy

Estimation of a speaker's direction and head orientation with binaural recordings can be a critical piece of information in many real-world applications with emerging `earable' devices, including smart headphones and AR/VR headsets.

The auto and cross angular power spectrum of the Cas A supernova remnant in radio and X-ray

no code implementations11 Feb 2021 Preetha Saha, Somnath Bharadwaj, Susmita Chakravorty, Nirupam Roy, Samir Choudhuri, Hans Moritz Günther, Randall K. Smith

We find that X-ray B is strongly correlated with both radio and X-ray A, however X-ray A is only very weakly correlated with radio.

The magnetic field in the dense photodissociation region of DR 21

no code implementations15 Dec 2020 Atanu Koley, Nirupam Roy, Karl M. Menten, Arshia M. Jacob, Thushara G. S. Pillai, Michael R. Rugel

From the OH 18~cm absorption, observed with the Karl G. Jansky Very Large Array, we find that the line of sight magnetic field in this region is $\sim 0. 13$~mG.

The visibility based Tapered Gridded Estimator (TGE) for the redshifted 21-cm power spectrum

1 code implementation6 Sep 2016 Samir Choudhuri, Somnath Bharadwaj, Suman Chatterjee, Sk. Saiyad Ali, Nirupam Roy, Abhik Ghosh

An earlier version of the 2D TGE for the angular power spectrum $C_{\ell}$ is improved and then extended to obtain the 3D TGE for the power spectrum $P({\bf k})$ of the 21-cm brightness temperature fluctuations.
