Effect of urbanisation & population density on groundwater in India using satellite remote sensing data
This work investigates the relationship of urbanization, population density and meteorological variables (temperature & precipitation) on groundwater storage for the selected study regions in India. Variations in ... -
Effects of aerosols and atmospheric boundary layer dynamics on refractive index fluctuations: implications for Free-Space Optical communication
Laser communication through atmospheric channels is an emerging wireless technology, commonly known as Free-Space Optical (FSO) communication. It facilitates unprecedented channel capacity and very large bandwidth, favouring ... -
Effects of Strong Electron-Electron Correlations on Band Insulators in Equilibrium and Non-Equilibrium
In this thesis, several aspects of correlation effects in band insulators that were hitherto not addressed, both in equilibrium and non-equilibrium, are studied using the Ionic Hubbard model (IHM) at half-filling and ... -
Efficient Algorithms for Learning Restricted Boltzmann Machines
The probabilistic generative models learn useful features from unlabeled data which can be used for subsequent problem-specific tasks, such as classification, regression or information retrieval. The RBM is one such important ... -
Efficient Transceiver Techniques for Media-based Modulation Systems
Conventionally, information bits are conveyed in a communication system by transmitting symbols from a complex modulation alphabet such as QAM or PSK. The wireless fading channel is viewed as a signal distorting medium ... -
Electric Field Assisted Self-Healing (eFASH)
Circuit failure due to the open faults in the interconnect is the most common problem regarding the reliability of electronic systems. This is particularly true for large-area electronic systems such as display, image ... -
Electric Field-Guided Alignment of Carbon Nanotubes in Polymer Matrix Composites for Structural Applications
Carbon nanotubes (CNTs) have been extensively researched for diverse applications in recent years. In the present work, the use of low frequency non-uniform alternating electric fields to manipulate the alignment behavior ... -
Electrochemical Behavior of Metallic Coatings Containing Carbonaceous Additives
Coatings have been traditionally used for protection against corrosion. Therefore, substantial efforts have been focused on engineering the microstructure and morphology of coatings to enhance their corrosion resistance ... -
Electrochemical Conversion of Methyl Ketones to Esters
The need for sustainable and efficient organic synthesis has inspired chemists to embrace classic technologies like electrochemistry and photochemistry. In addition to being an environmentally benign method to synthesize ... -
Elucidating Intricate Excited-state Dynamics in Molecular Systems Using Time-resolved Transient Absorption and Ultrafast Raman Spectroscopy
Abstract The excited-state dynamics of molecular materials is of great importance to understand early time photodynamics. We have used Femtosecond Transient Absorption (fs-TA) and Ultrafast Raman Loss Spectroscopy (URLS) ... -
Elucidating the role of carbon metabolism genes chiA and yjiY in Salmonella pathogenesis.
Salmonella is a foodborne pathogen that causes debilitating enteric diseases in a wide range of hosts. While Salmonella Typhimurium causes self-limiting gastroenteritis in human beings, Salmonella Typhi causes typhoid fever ... -
Embedding Networks: Node and Graph Level Representations
Graph neural networks gained significant attention for graph representation and classification in the machine learning community. For graph classification, different pooling techniques are introduced, but none of them has ... -
Embryonic Expression of Cytokines: Functional Role of Il-1β During Blastocyst Hatching
The detailed investigation on the embryo-endometrial cytokine expression, in both mouse and hamster, was carried out during the peri-hatching development and it is described in chapter 2. We hypothesize that, for a ... -
EMF: System Design and Challenges for Disaggregated GPUs in datacenters for Efficiency, Modularity and Flexibility
With Dennard Scaling phasing out in the mid-2000s, architectural scaling and hardware specialization take centre stage to provide performance bene fits with already stalling Moore's law. An outcome from this hardware ... -
Emulation of wind turbine and sensorless control of doubly-fed induction generator for wind energy application
Wind energy utilization has been growing at a rapid rate, fuelling research and development in wind turbine – generator systems. Doubly fed induction generator (DFIG) driven by a wind turbine is a commonly used wind energy ... -
Energetics of monsoon variability over the last 22,000 years
The interpretation of proxies of paleo monsoons has been based primarily on changes in incident solar radiation. The role of feedbacks has not been examined in depth. In this thesis, we have used a diagnostic model of ... -
Engineered Nanomaterials: Array-based Sensing of Biological and Chemical Analytes
Array-based sensing, also known as chemical nose/tongue analysis, offers an alternative platform for simultaneous differentiation of a wide range of analytes using a fixed number of cross-reactive receptors. The sensor ... -
