On curve reconstruction in Riemannian Manifolds: ordering motion frames
(Dhirubhai Ambani Institute of Information and Communication Technology, 2012)In this work we generalize the computational geometric curve reconstruction approach to curves embedded in Riemannian manifolds. We prove that the minimum spanning tree, given a sufficiently dense sample, correctly ... -
On designing DNA codes and their applications
(Dhirubhai Ambani Institute of Information and Communication Technology, 2019)Bio-computing uses the complexes of biomolecules such as DNA (Deoxyribonucleic acid), RNA (Ribonucleic acid) and proteins to perform the computational processes for encoding and processing the data. In 1994, L. Adleman ... -
On heterogeneous distributed storage systems: bounds and code constructions
(Dhirubhai Ambani Institute of Information and Communication Technology, 2019)In Distributed Storage Systems (DSSs), usually, data is stored using encoded packets on different chunk servers. In this thesis, we have considered heterogeneous DSSs in which each node may store a different number of ... -
On large scale near-independent blind source separation
(Dhirubhai Ambani Institute of Information and Communication Technology, 2015)The thesis addresses Blind Source Separation (BSS) in Large Scale (LS) and near-Independent (nI) sources scenario. The large scale in BSS imply number of unknown sources ranging from 15 to 140, so that the corresponding ... -
Peer-to-peer communication in mobile social network
(Dhirubhai Ambani Institute of Information and Communication Technology, 2016)Peer-to-peer opportunistic communication between mobile devices carried by humanswithout using any infrastructure is largely unexploited. As these devices are carried byhumans, their encounter pattern depends on human ... -
