Towards Secure and Efficient Realization of Pairing-Based Signatures from Static Assumptions.
Bilinear pairing defined over elliptic curve group was first used to design novel cryptosystem in 2000. Since then a large number of cryptosystems has been proposed in pairing-based cryptography (PBC). The main tool for ... -
Caenorhabditis elegans-Bacteria interactions: Neuronal Regulation of Innate Immune Responses
The survival of an organism depends on its ability to sense threats and execute appropriate defense mechanisms. C. elegans is a soil-dwelling nematode that feeds on bacteria in rotting vegetation. The nematode has few ... -
Structure-Function Analysis of Focal Adhesion Protein Vinculin in Neocortical Axon Growth and Development
Axon growth and extension are dependent on the interaction of neurons with extracellular matrix (ECM). The interaction between cells and ECM is known as focal adhesion (FA). Vinculin is one the major proteins of FA complex ... -
Understanding Conformal Field Theory in Mellin Space
In the last decade, there has been tremendous progress in understanding conformal eld theories in more than two space-time dimensions. The numerical bootstrap framework has been pushed to a very advanced level of ... -
Self-assembled Coordination Architectures & Donor- Acceptor Systems: Synthesis, Characterization and Applications
Self-assembled Coordination Architectures & Donor-Acceptor Systems: Synthesis, Characterization and Applications Atul Kumar The extraordinary ability of biological systems to develop complex and functional molecular ... -
Learning Tournament Solutions from Preference-based Multi-Armed Bandits
We consider the dueling bandits problem, a sequential decision task where the goal is to learn to pick `good' arms out of an available pool by actively querying for and observing relative preferences between selected pairs ... -
Accelerated search for thermoelectric and topological materials using first-principles and machine learning
In summary, we have performed first-principles calculations to study the topological phase transitions in chalcopyrite compounds as a function of hydrostatic pressure. These compounds are topological insulators in the ... -
Pronunciation assessment and semi-supervised feedback prediction for spoken English tutoring
Spoken English pronunciation quality is often influenced by the nativity of a learner, for whom English is the second language. Typically, the pronunciation quality of a learner depends on the degree of the following four ... -
Adaptive Dielectric Thin Film Transistor : A Self-Configuring Device for Low Power Electrostatic Discharge Protection
Large area and flexible electronic systems are widely used in applications such as displays, image sensors, wearable electronics, and energy harvesting systems. One of the fundamental functional blocks in these systems is ... -
Fabrication and Characterization of Optomechanical Devices
Silicon photonics is a promising platform for photonic devices and circuits, largely driven by advanced complementary metal-oxide-semiconductor (CMOS) processing technology. An extremely crucial component for a photonic ... -
Analysis of Kinematic Constraints in Fixed-Wing UAV Formation Flying
Rise in autonomy has led to increase in usage of Unmanned Aerial Vehicles (UAVs) for various applications and has allowed the UAVs to perform complex and hazardous missions with ease. Formation of multiple UAVs finds ... -
1H-NMR Study of Proton Glasses - Nuclear Spin Lattice Relaxation in BPxBPI(1-x) and BPxGPI(1-x) - Effects of Disorder on the Proton Group Dynamics
Mixed systems made from a combination of ferroelectric (FE) and antiferroelectric (AFE) compounds, exhibit various effects of disorder in different temperature regions. The kind of effects observed, depend on the technique ... -
Rheology of Dense Granular Chute Flows
Granular flows have always fascinated researchers through its complex and mysterious behavior. Although a collection of solids, they exhibit properties like that of fluids. Flows over an inclined plane, known as chute flow, ... -
Efficient and Secure Search over Encrypted Data
Due to a variety of crucial bene fits, enterprises outsource their data to cloud resident storage. The outsourced data needs to be stored in encrypted form on remote untrusted servers to preserve privacy. However, if the ... -
Structural Health Monitoring with Laser Doppler Imaging of Ultrasonic Guided Waves
This thesis deals with ultrasonic guided wave based non-destructive inspection and health monitoring of aircraft structural components using a non-contact sensing scheme based on laser Doppler scanning imaging technique. ... -
Morphology and topology of cosmological fields during the Epoch of Reionization
In this thesis we have introduced a real space morphological tool, Contour Minkowski tensor (CMT) to analyse the 21cm brightness temperature field from EoR. We showed that the size and shape information of structures ... -

The thesis is entitled as "Development of Novel NMR Methodology and Investigation of Challenging Chemical Problems ". The research work reported in this thesis is mainly carried out in two directions. The initial focus ... -
Design and Analysis of Surface Acoustic Wave Filters
The generation and detection of surface acoustic waves (SAWs) using interdigital transducers (IDTs) on a piezoelectric surface have been used to produce many high performance Band Pass Filters. This thesis focuses on ... -
Program Analyses to Support Memory-saving Refactorings in Java Programs
Software commonly consumes unexpectedly high amounts of memory, frequently due to programming idioms that are used to make software more reliable, maintainable and understandable. In the case of modern object-oriented ... -
Cross-Modal Retrieval and Hashing
The objective of cross-modal retrieval is to retrieve relevant items from one modality (say image), given a query from another modality (say textual document). Cross-modal retrieval has various applications like matching ...
