Deliberations on Borrower Behaviour in the Context of Micro-finance
Micro-finance, a popular tool for poverty alleviation, has witnessed a cycle of reaching out to the credit strapped, recording high recovery rates, scaling up exponentially and facing mass defaults, world-over. The two ... -
Differential DNA methylation patterns in primary and recurrent glioblastomas : Protumorigenic roles of Tumor Endothelial Marker 8 (TEM8) and ASAP1 genes
Glioblastomas (GBMs) are clinically aggressive malignant brain tumors in adults with a median survival of 14 months on diagnosis. Therapeutic interventions such as debulking surgeries, chemotherapy, and ionizing radiation, ... -
Representation of Natural Stimuli in Neural Signals across Scales and Frequencies
Neural activity from the brain can be recorded at different scales using a variety of electrodes, which vary in their resolution, cortical spread and invasiveness. The electroencephalogram (EEG) is recorded from the scalp, ... -
Influence of Soil's Electrical Parameters on Lightning Stroke-current Evolution and Fields in the Close Range
The lightning return stroke forms one of the severest natural sources of electromagnetic interference for ground-based and airborne systems. Many physical fields are involved in this complex physical phenomenon. Several ... -
Investigations on Increasing Linear Modulation Range in Hybrid Multilevel Inverter Fed Induction Machine Drives Regardless of Load Power Factor
Nowadays, multilevel inverters (MLIs) have become a promising alternative to the twolevel inverter in medium voltage high-power applications such as motor drives, active power filters, HVDC, electric vehicles, wind, and ... -
Ion insertion and Ion-host Interactions in Diketopyrrolopyrrole-based π-Conjugated Polymers
π-conjugated organic semiconductors are a class of technologically important materials with broad applicability in areas as diverse as energy conversion and storage, bioelectronics, and consumer electronics. This is because ... -
Translation from batch to continuous processing of metal nanoparticle synthesis and application metallic nanostructures printed on flexible substrates
One of the key challenges in nanoparticle synthesis is the quality control on scaling up the operation from bench to plant scale, which is constrained by conventionally adopted batch operation. Translation from batch ... -
Nonlinear Optical Enhancement Studies in Silicon-based Resonant Metasurfaces
Metasurfaces are two dimensional arrangements of building blocks called meta-atoms which have been found to be useful to manipulate amplitude, phase, polarization of light at the nanoscale. Using these properties, functional ... -
Robustness of Neural Activity Dynamics in the Medial Entorhinal Cortex
Biological systems exhibit considerable heterogeneity in their constitutive components and encounter stochasticity across all scales of analysis. Therefore, central questions that span all biological systems are: (a) How ... -
Inverse Problems in 3D Full-wave Electromagnetics
An inverse problem in Electromagnetics (EM) refers to the process of reconstructing the physical system by processing the measured data of its electromagnetic properties. Inverse problems are typically ill-posed, and this ... -
Multi-level Partitioning Algorithms & Reliability Analysis for Transit Networks
Public transit systems are an indispensable part of any metropolitan city. Its success depends on many factors, chief among which is the ease with which users can query for optimal journeys using mobile apps. Conventional ... -
Development of Microneedles for Transdermal and Intradermal Drug Delivery
Transdermal drug delivery has an enormous potential for painless therapeutics. Many drugs designed for systemic action are more efficient when delivered through the skin compared to oral administration as their degradation ... -
Performance Characterization and Optimizations of Traditional ML Applications
Even in the era of Deep Learning based methods, traditional machine learning methods with large data sets continue to attract significant attention. However, we find an apparent lack of a detailed performance characterization ... -
Regional and Local-scale Analysis of Landslides Induced by Rainfall and Earthquakes
Landslides are major natural disasters which pose a significant risk to lives and infrastructure globally. As urbanization is increasing due to the increasing population in mountainous regions, the risk due to landslides ... -
Towards Electronic Scale Dynamics of Chemical Bonding in Isolated Molecules and Solvated Species
The chemical bonding in molecules and molecular clusters is determined by the nature of the electron density distribution between the atoms. Over the past century, different theories such as Lewis’s bond, valence-bond ... -
Optimizing Matrix Multiplication for the REDEFINE Many-Core Co-processor
Matrix-matrix multiplication is an important operation for many applications and hence it is required to be parallelized optimally for the architecture the applications will run on. REDE- FINE is a many-core co-processor ... -
Transport of Intensity Equation based Quantitative Phase Imaging of Red Blood Cells
This thesis reports the characterization of Red Blood Cell (RBC) morphology in a non-contact and label-free manner using a flexible, low-cost continuous imaging system. Detection of abnormalities in red blood cell ... -
Learning to Perceive Humans From Appearance and Pose
Analyzing humans and their activities takes a central role in computer vision. This requires machine learning models to encapsulate both the diverse poses and appearances exhibited by humans. Estimating the 3D poses of ... -
Design, Control and Experimental Validation of a Robust Adaptive Feedback Linearization Controller for a Quadcopter Manipulator System
A quadcopter manipulator system (QMS) is an aerial robot comprising a quadcopter with a three degree of freedom manipulator mounted at the bottom of the vehicle. An aerial robot can reach otherwise inaccessible ... -
Crustal evolution and tectonic processes of the Madras Block, India
The Neoarchaean (2.8–2.5 Ga) era in the earth’s history witnessed significant crustal growth related to the amalgamation and dispersion of ancient continents. The processes leading to the formation and destruction of the ...
