Internship/ Project Work

2022

Completed Internship at NTT Research, Sunnyvale, USA under Dr. Pratish Dutta from Feb-Oct 2022.

2019

Application of Linear Algebra in Page Rank

Supervisor   : Prof. Avishek Adhikari
Description : In this project, we have came up with different Page Rank algorithms from linear algebra point of view and also from dynamical and probabilistic point of view.

2018

p-adic Analysis Compared with Real

Supervisor    : Prof. Avishek Adhikari
Description : In this project, we confined our considerations into the description of p-adic norm and the field of p-adic numbers. We mentioned some of its beautiful features and some of its warts, the sole
sole purpose of such discussion is to compare the topology of field of p-adic numbers with topology of reals.
