High Performance Hybrid Drive for Induction Motor Using Transient Angle Estimation and Control
Induction motors are widely used in industry because of their ruggedness, higher power/ weight ratio and low maintenance. The development of variable frequency drives for induction motors have resulted in higher performance. ... -
Structure-Activity Correlation and Mechanistic Investigations of Glutathione Peroxidase-Like Catalytic Activity of Diaryl Diselenides
Hydroperoxides are very harmful and they can oxidize several biomolecules, causing different disease states. Glutathione peroxidase (GPx) is a mammalian selenoenzyme which protects human body from oxidative damage by ... -
Investigations into the Synthesis, Structural, Dielectric and Optical Properties of Multifunctional M2NaNb5O15 (M=Ba, Sr) Nanocrystals and Glass Nanocrystal Composites
The physical properties of borate-based glasses comprising crystallites of inorganic materials (polar) at different length scales have become increasingly important owing to their importance in the design and fabrication ... -
Nucleoid-associated Proteins of Mycobacterium tuberculosis : Insights into their Functions
Bacteria face the challenging task of compacting their chromosomes to accommodate them in a small cytoplasmic volume and at the same time maintaining the nucleoids in a highly organized and dynamic state for transcription, ... -
Understanding the Regulation of mRNA Translation Repression by RGG-motif Proteins
Messenger RNA translation is one of the most energy expensive steps in the process of gene expression and therefore translation regulation is critical for maintaining cellular homeostasis. In contrast to transcriptional ... -
Modeling the Dependence Structure of Hydroclimatic Extremes
Analysis of extremes in a complex interacting hydroclimatic system is challenging due to rarity of events, small sample size, poor state of data or missing data, lack of statistical tools for analyzing observed changes and ... -
Observational study of Core-Collapse Supernovae
The advent of dedicated surveys for studying transient events has invoked a great interest in the study of supernovae (SNe). The rate of discovery of SNe has hence gone up ten-fold relinquishing their diversity. SNe not ... -
Fiber Bragg Grating Based Sensing Devices for Novel Applications in Bio-medical and Engineering Fields
Sensors have been an integral part of human life. Various sensor technologies have contributed in their own ways to fulfill specific requirements for aiding human beings. In this context, fiber optic sensors have several ... -
Ischemic Concentrations of Lactate Increase TREK1 Channel Activity and Expression
TREK1 is a two-pore domain leak potassium channel which contributes to resting membrane potential. TREK1-/- mice exhibit increased neuronal mortality after global ischemia. Neuroprotective agents like volatile anesthetics ... -
Structural and Functional Characterization of Enzymes of Proline Biosynthesis Pathway in Mycobacterium tuberculosis
Tuberculosis is the second largest killer disease on global scale after HIVAIDS. The rapid evolution of Mycobacterium tuberculosis into drug resistant strains and the toxicity of these drugs are the major constraints in ... -
Structural and Electrochemical Investigation of Fluoro(hydroxy)phosphate Based Cathode Materials for Secondary Batteries
Structural and electrochemical investigation of LiFePO4OH hydroxyphosphate material. The synthesis and structure of this material is explained. The hydrothermally synthesized material crystallizes in triclinic structure ... -

Photodetectors are widely used as image sensors, in optical communication, remote sensing etc. IR detectors find widespread applications in night vision cameras and medical diagnostics. In this thesis a new chalcopyrite ... -
Design, Development and Characterisation of piezoelectric microvalve for electric propulsion system
The advanced geostationary communication satellites have shown trends in terms of increased power, life and payload mass. For these platforms, Electric Propulsion Systems (EPS) offer an attractive option for overall mass ... -
Sparse bounds for various spherical maximal functions
Harmonic analysis mainly deals with the qualitative and quantitative properties of functions and transforms of those functions. It has applications in various areas of Mathematics like PDE, Differential geometry, Ergodic ... -
Resource allocation during Flavivirus lifecycle
Single-stranded RNA virus infection cycle progresses by resource (viral RNA) allocation to segregated macromolecular complexes: host ribosomes (translation), viral RNA polymerase (replication) and viral structural proteins ... -
Syntheses and Structure Elucidations of Co-crystal with Nicotinamide Co-former
Abstract : Co-crystals consist of two or more components that form a unique crystalline structure having unique properties. The components interact via non-covalent, ionic interaction, van der Waals interactions and π-π ... -
Hydrologic Inference: A Complex Systems Approach
The aim of this thesis is to understand linkages between hydrologic processes and patterns from the perspective of a complex system. In hydrologic systems, there exist interactions of hydrologic components among themselves ... -
Evaluation of Power-Law Creep in Bending
