Data-efficient Deep Learning Algorithms for Computer Vision Applications
The performance of any deep learning model depends heavily on the quantity and quality of the available training data. The generalization of the trained deep models improves with the availability of a large number of ... -
Data Driven Stabilization Schemes for Singularly Perturbed Differential Equations
This thesis presents a novel way of leveraging Artificial Neural Network (ANN) to aid conventional numerical techniques for solving Singularly Perturbed Differential Equation (SPDE). SPDEs are challenging to solve with ... -
Influence of surface topography on wear and debris morphology of polymers
The artificial knee and hip joints comprise a polymer-metal tribological system where soft polymers slide against hard metallic surfaces. When a polymer slides on it, the micro hard asperities remove the polymers in the ... -
Integrated Optic Waveguide Bragg Grating Devices in Silicon-on-Insulator and Their Applications: Design, Analysis and Fabrication
Integrated Waveguide Bragg Gratings are on-chip counterparts of Fiber Bragg Gratings. The working principles are similar, and functionalities could be explained with Coupled Mode Theory. Periodic index contrast required ... -
Aspects of Holography and Quantum complexity
We begin with the Principle of holography and the AdS/CFT correspondence. We begin our investigations by considering the Principle of Holography, at the level of codimension-1 screens. We argue that the mechanism of encoding ... -
Inclusive and Eye-Gaze Controlled Human-Robot Interaction for Persons with Severe Speech and Motor Impairment
Most individuals perform various activities of daily living without having to con sciously think and plan about them. People talk, cook their food, move around the house, drive to their workplace and schools, play sports, ... -
Improved approximation bounds on maximum edge q coloring of dense graphs
The anti-Ramsey number ar(G,H) with input graph G and pattern graph H, is the maximum positive integer k such that there exists an edge coloring of G using k colors, in which there are no rainbow subgraphs isomorphic to ... -
Gravity flow of granular materials through a vertical channel
Grains and powders are the second most widely used materials in industries and daily life after simple fluids. There are a variety of granular materials such as food grains, detergents, tablets and capsules, fertilizers, ... -
Analysis of Residual Estimate of Local Truncation Error
This thesis focuses on understanding the behaviour of the residual error estimator, referred to as R- parameter, in the context of Finite Volume Method. R-parameter measures the local truncation error (LTE) which is generated ... -
Stochastic Optimization And Its Application In Reinforcement Learning
Numerous engineering fields, such as transportation systems, manufacturing, communication networks, healthcare, and finance, frequently encounter problems requiring optimization in the presence of uncertainty. Simulation-based ... -
Flavivirus RNA replication: Probe development, structural dynamics, and role of zinc ions.
Flaviviruses share a typical genome architecture where the highly conserved UTRs flank a central coding region. They also share a common genome replication strategy called genome cyclization where the UTRs interact to form ... -
Homogenization of PDEs on oscillating boundary domains with L1 data and optimal control problems
This thesis comprehensively studies the homogenization of partial differential equations (PDEs) and optimal control problems with oscillating coefficients in oscillating domains. After the introduction, the thesis is divided ... -
Isoform Specific Synthetic Glutathione Peroxidase Mimetics in Redox Regulation of Cell Death and Diseases
Reactive oxygen species (ROS)-induced oxidative stress has been implicated in various pathologies and cell death processes. Cells have antioxidant systems to neutralize the harmful effects of excess ROS. Glutathione ... -
Leveraging KG Embeddings for Knowledge Graph Question Answering
Knowledge graphs (KG) are multi-relational graphs consisting of entities as nodes and relations among them as typed edges. The goal of knowledge graph question answering (KGQA) is to answer natural language queries posed ... -
Augmenting Hyperspectral Image Unmixing Models Using Spatial Correlation, Spectral Variability, And Sparsity
Hyperspectral imaging sensors sample sunlight reflected from different targets on Earth's surface by utilising a series of contiguous narrow spectral channels. The higher spectral resolution of hyperspectral images (HSIs) ... -
Algorithms for Online Learning in Structured Environments
Online learning deals with the study of making decisions sequentially using information gathered along the way. Typical goals of an online learning agent can be to maximize the reward gained during learning or to identify ... -
Parallel methods to solve large-scale stochastic linear and nonlinear mechanics problems in a domain decomposition framework
Parallel methods to solve large-scale stochastic linear and nonlinear mechanics problems in a domain decomposition framework Mechanics problems with inherent uncertainties are mathematically modeled using stochastic partial ... -
Dissecting the function of NuMA in cleavage furrow formation and chromatin decondensation at the mitotic exit in animal cells
In animal cells, the duplicated genetic material is aligned on a microtubule-based structure known as the mitotic spindle during mitosis. At the mitotic exit, the mitotic spindle elongates, and the sister chromatids get ... -
