Investigations into Extending the Linear Modulation Range of Hybrid Three-Level and Five-Level Inverters for Variable Speed Drive Applications
Multilevel inverters (MLIs) are highly sought after for medium to high voltage applications, such as traction drives, fans, blowers, HVDC, and FACTS. These inverters provide numerous benefits over conventional two-level ... -
Computational Approaches to Engineering Antibody Responses to HIV
Efforts are underway to devise interventions that would control HIV infection without the need for lifelong antiretroviral therapy. A key strategy involves the elicitation of endogenous antibodies that can neutralise diverse ... -
Group Testing: A Probably Approximately Correct Analysis and Recovery Algorithms for pooled RT-qPCR
The goal of group testing, also called pool testing, is to successfully identify a set of k defectives from a population of n items using only m (< n) group tests. In each group test, a subset of the n items is tested ... -
Studies of Carbohydrate-Conjugated Anthracenes in Self-Assembly, Bioimaging and Photosensitization
Conjugation of a carbohydrate moiety to an aromatic core leads to glycostructures that possess a high propensity for self-assembly in aq. solutions, driven primarily by π-stacking of the aromatic ring, as well as, the ... -
Adaptation and Characterization of Fossilized Hydrocarbon Gas Turbine Combustor for Operation with Green Fuel(s): Experimental and Numerical Investigation
Decarbonizing energy conversion systems necessitates the adaptation of conventional fossil-fuel-based systems, which have been designed and optimized over the past century for operation with fossilized hydrocarbons, to ... -
Contaminated Site Investigation and Remediation Using Modified Nano Zero Valent Iron Particles
Rapid industrialization has boosted economic growth but also increased contaminants in air, water, and soil. Improper disposal of municipal solid waste and industrial effluents has rendered many groundwater sources unfit ... -
Design and Development of Novel Quadcopters for Reliable Operations in Cluttered Environments
This thesis presents innovative designs and control strategies for enhancing the performance and reliability of quadcopters, particularly in demanding and cluttered environments. The primary contributions include the ... -
Label Efficient and Generalizable No-reference Video Quality Assessment
No-reference (NR) video quality assessment (VQA) refers to the study of the quality of degraded videos without the need for reference pristine videos. The problem has wide applications ranging from the quality assessment ... -
Designing Quality of Service aware Serverless Platforms
Serverless computing is a widely used Cloud computing service offering that provides users with managed runtimes to develop their business logic as functions. It supports eventdriven execution of functions and a powerful ... -
Design of Placement Delivery Arrays for Shared Cache and Multi-antenna Coded Caching Problems
Caching has been considered as a promising technique to handle the exponential growth of wireless data traffic. The caches distributed across the network are utilized to shift some of the peak-hour traffic to off-peak ... -
Foaming of Surface Waterbodies: A Comprehensive Study on Causes, Persistence, Seasonality, and Mitigation Strategies
Foaming waterbodies have emerged as a significant global concern due to their adverse effects on aquatic ecosystems, offensive odour emissions, disruption of daily activities in nearby areas, and visual unpleasantness. ... -
Study of Optical Coupling of Excitons & Trions in Colloidal Quantum Wells with Photonic Metasurface Resonators & Microcavities
Quantum photonics held immense potential for applications such as quantum metrology and cryptography. In this thesis, we investigated the optical properties of colloidal quantum wells (CQWs) integrated with photonic ... -
Aeroacoustic Sources in Twin Turbulent Jets
An understanding of the aeroacoustics of twin turbulent jets is essential for applications involving noise reduction in dual engine aircrafts and launch vehicles. The aeroacoustic dynamics of these jets are influenced ... -
4D Printing of Polymer Composites to Engineer Resorbable and Deployable Implants
Medical implants include products that are used to replace or restore the function of any damaged organ or tissue inside the body. The current generation of implants are mostly made from non-degradable materials and are ... -
Thermochemical Conversion of Lignocellulosic Biomass to Generate Hydrogen Rich Synthesis Gas for Hydrogen Production: An Experimental and Thermodynamic Study Using Oxy-Steam as The Gasification Agent
Hydrogen can help decarbonize and bring a paradigm shift in the global energy mix. Green hydrogen, with its potential to mitigate carbon emission, offers an inexhaustible supply – free from the constraint of finite reserves. ... -
Mathematical and Computational Modelling Investigations of the Role of Trait Variation in Savanna-Woodland Bistable systems
Over the last decade, several studies have shown the importance of individual variation in natural populations. Theoretical ecological studies are beginning to incorporate trait variations in models, but they continue to ... -
