Intraseasonal Variability in Aquaplanet Configuration of Community Atmosphere Model
The Intraseasonal Oscillation (ISO) plays an important role to modulate deep convective activity in the tropical region. In this thesis, I aim to understand the role of land and warm oceans in ISO, using a general ... -
Algorithms for Fair Decision Making: Provable Guarantees and Applications
The topic of fair allocation of indivisible items has received significant attention because of its applicability in several real-world settings. This has led to a vast body of work focusing on defining appropriate fairness ... -
Role of an RNA Polymerase Interacting Protein, MsRbpA, from Mycobacterium smegmatis in Phenotypic Tolerance to Rifampicin
Rifampicin is a non-competitive inhibitor of bacterial RNA polymerase (RNAP). The knowledge about the mechanism of action of this drug has emanated from the genetic and the biochemical studies carried out on Escherichia ... -
Sustainable and Energy Efficient Treatment Potential of Mixed Algal Consortia for High Nutrient Organic Wastewaters
The increasing levels of generation of nutrient rich wastewaters around the world pose serious challenges where conventional biological and chemical methods of treatment have gradually begun to fail in meeting sustainability ... -
Hammer Energy Ratios of Different Spt Setups Using Indigenous Hammer Energy Measurement Apparatus
Standard Penetration Test (SPT) is carried using different components and lifting mechanisms, which causes variation in energy efficiency and the inverse relationship between energy transferred to drill rod and N value was ... -
Investigating the role of mantle convection in affecting surface deformation and topography in the Indian plate and the India-Eurasia collision zone
The India-Eurasia collision zone has been a subject of various studies that have tried to explain the forces behind the high elevation and large scale continental deformation in this region. However, the relative contribution ... -
GRACE-based Assessment of Climatic Controls on Hydrological Variables
Anthropogenic climate change is now well-established and is expected to have serious implications on Terrestrial Hydrologic cycle. This inspired scientific investigation to assess the impact of various climatic processes ... -
Rv0805, a novel regulator of central carbon metabolism and cell envelope properties in mycobacteria
Metabolic flexibility is one of the key factors that underpin mycobacterial physiology and pathogenesis. During infection, mycobacteria shift towards utilising host-derived fatty acids, lipids, cholesterol and cholesterol-esters. ... -
Sampling of Structured Signals: Techniques and Imaging Applications
The celebrated Shannon sampling theorem is a key mathematical tool that allows one to seamlessly switch between the continuous-time and discrete-time representations of bandlimited signals. Sampling and reconstruction of ... -
Understanding quantitative process physics of 3D binderjet printing with validation in Ti-6Al-4V and inkjet bioprinting of mammalian cells
In the field of additive manufacturing, laser or electron beam based 3D printing is widely investigated for biomedical applications. However, much less explored is the binderjet 3D printing, which allows processing of ... -

The thesis entitled “Nucleophilic Addition reactions of 2-Aza-allyl anion: Application to the Total Synthesis of Natural Products’’ is divided into two sections with an appendix. First section of the thesis details the ... -
Modeling, Characterization, Control and Design of Switched Reluctance Machines
Switched reluctance machines (SRM) are permanent magnet free, and have a simple rotor construction with no current carrying parts. These are particularly suitable for high-temperature and high-speed applications. However, ... -
Development and Application of Fiber Optic Sensors for Structural and Flight Testing of Aircraft
Structural testing deals with sensing of health parameters such as strain, temperature, vibration, etc. of different structures like aircrafts, ships, bridges, dams, buildings, etc. and it is important from the viewpoint ... -
A Nash Bargaining Based Bid Optimizer for Sponsored Search Auctions
The on-line advertising market involving displaying of Ads against search results by a search engine is growing at a fast rate. A majority of the search engine companies sell their advertising space through auctions which ... -
Lineage delimitation and diversification in Nyctibatrachus, an endemic frog genus from the Western Ghats
Determining how biodiversity is produced and maintained remains one of the fundamental questions in ecology. The phenomenon of diversification, which occurs via the interplay of speciation and extinction, holds the key ... -
Optical, Electrical and Photo-physical Investigations of Cd(Hg)Te Nanostructures Synthesized by Solvothermal Method
The thesis investigates the optical, photo-physical, and electrical properties of CdTe and HgCdTe nano- and micro-structures synthesized by hydrothermal/solvothermal technique. Application oriented studies like fluorescence ... -
Synthesis and Conformational Analysis of Peptides Containing the Gamma Amino Acid Residue Gabapentin
Insertion of amino acid residues into all polypeptide backbones leads to an expanded repertoire of secondary structures. In the present thesis an attempt has been made to explore the conformational properties of the ... -
Fatigue Crack Growth in Roller-Rocker and Rocker Bearings of Railway Steel Bridges
Indian Railways comprise a major part of the infrastructure in India. Most of the transportation of raw materials, goods, and people from different parts of the country is done by the railways. To cope with the ever-increasing ... -
Safe Operating Area Reliability of AlGaN/GaN High Electron Mobility Transistors (HEMTs)
Gallium Nitride (GaN) based high electron mobility transistors (HEMTs) are extensively considered for power switching and RF applications by the virtue of their unique properties. However, despite of its attractive ... -
