Hardware Emulation of a Long Transmission Line by High Frequency Power Electronic Converter for the study of Switching Transients
To ensure smooth functioning of the grid, the reliability and robustness of the power system equipment needs to be precisely evaluated during their development process. But direct on- eld tests of most of the equipment ... -
Charge transport in functionalized carbon nanotube and composite with polyaniline at low temperature
Carbon nanotube (CNT) is a very well-known material with very high thermal conductivity, high Young modulus and high electrical conductivity. The sp2 bonded C=C π-electrons delocalize in the whole lattice give rise to high ... -
Kinetic, Catalytic and Epigenetic Properties of HpyAXVII DNA Methyltransferase – a Phasevarion in the Human Pathogen Helicobacter pylori
Helicobacter pylori is the leading cause of gastric cancer in human beings. It is a helix-shaped, Gram-negative, motile bacteria that colonizes the gastric mucosa and eventually the gastric epithelium. It has an overabundance ... -
Robust Algorithms for recovering planted structures in Semi-random instances
In this thesis, we study algorithms for three fundamental graph problems. These are NP-hard problems which have not been understood completely as there is a signifiicant gap between the algorithmic and the hardness fronts ... -

Design, Synthesis and Optical Characterization of 1,8-Naphthalimide based D-pi-A System Luminescent materials find a lot of application in the field of OLEDs and bio-medical applications [1-2]. Our group has recently ... -
Towards an Integrated Graphene Nano-Opto-Electro-Mechanical System
Micro-electromechanical systems (MEMS) have found extensive applications in micromechanical sensing. The scaling of MEMS into nano-electromechanical systems (NEMS) was spurred primarily by the expectation of higher ... -
Quantum capacitance and noise measurements in van der Waals heterostructures
The discovery of graphene has revolutionized the field of condensed matter physics and opened new prospects for a wide range of other two-dimensional materials. Further with the advancement of fabrication techniques, one ... -
Evaluating Climate Change Mitigation & Adaptation Potential of Sustainable Urban Transport Measures in India
The global climate is transforming due to increased GHG emissions. Globally, the response to climate change has been through mitigation to reduce greenhouse gas emissions. Urban transportation is the second leading source ... -
Neuro-electronic Hybrid Systems
Artificial neural networks have provided a powerful motif to implement extremely complex functions of high dimensional inputs like images and text. These are now being used to directly control robotic systems, to enable ... -
Biochemical characterization of UvrD helicase and its 1 interplay with DNA mismatch repair proteins in 2 Neisseria gonorrhoeae
UvrD helicase belongs to type I superfamily of helicases. It participates in Nucleotide Excision Repair (NER) and DNA Mismatch Repair (MMR). It also participates in the rolling circle replication. It has been shown that ... -
Structural and functional studies on a small Heat Shock Protein from Entamoeba histolytica
Small Heat Shock Proteins (sHSPs) are molecular chaperones that bind to unfolding proteins during cellular stress to prevent them from aggregation. Once the normal conditions are restored, sHSPs release the bound substrate ... -
Information Extraction and Mapping for Populating Ontologies in Product Lifecycle Management
Computer-based tools used to manage a product's lifecycle from the cradle to the grave need to share product information across phases. If this information is well structured, accessing, and manipulating such information ... -
Tactile Cyber-Physical Systems: A Testbed, A Performance Metric and Network Resource Allocation Protocols
Tactile Cyber-Physical Systems (TCPS) use haptic, audio and video modalities to facilitate humans to perform real-time physical interaction of remote objects over ultra-low latency and ultra-reliable networks referred to ... -
Study of room temperature coupling of colloidal quantum dots to plasmonic arrays and metamaterials: from single quantum dot to quantum dot assemblies
There is much current interest in coupling emitters, such as fluorescing dye molecules and semiconductor quantum dots to plasmonic systems. Controlling the electromagnetic interactions between quantum emitters and the ... -
Development of PZT Based PiezoMEMS for Fluid Property Sensing
