Self-healing in Space Electronics Circuits
Self-healing in space electronics carries the possibility of creating a paradigm shift in engineering space systems with lesser complexity and mass. Space electronics plays a crucial role in the success of a mission as it ... -
Mechanics of cutting in granular media
Cutting is an important deformation process encountered during many instances in the engineering of infrastructure, such as trawling, trenching, and excavation. This thesis presents the results of an experimental program ... -
Service scheduling with Service, Waiting and Dissatisfaction costs
Service or job scheduling problems arise in many contexts such as cloud computing, task scheduling in CPUs, traffic routing and scheduling, production scheduling in plants, scheduling charging of electric vehicles (EVs), ... -
Accelerating Estimation of Perfusion Maps in Contrast X-ray Computed Tomography using Many-core CPUs and GPUs
X-ray Computed Tomography (CT) perfusion imaging is a non-invasive medical imaging modality that has been established as a fast and economical method for diagnosing cerebrovascular diseases such as acute ischemia, sub-arachnoid ... -
Radical and Lewis Acid Mediated Syntheses of Panaginsene, Indole-Fused Azabicyclo[3.3.1]Nonane and Davanoids
The thesis contains radical and Lewis acid-mediated syntheses of panaginsene, indole-fused azabicyclo[3.3.1]nonanes, and davanoids. The thesis includes three chapters; chapter-I contains the total synthesis of panaginsene, ... -
Raman Studies of Topological Crystalline Insulator, Natural Heterostructures, Excitonic Insulator and Layered Oxide Under Pressure
The theme of this thesis is Raman spectroscopic study of a variety of exotic states of matter under extreme conditions, such as, hydrostatic pressure as high as 25 GPa and a wide temperature range from 77 K to 390 K. Raman ... -
Diverse Applications of Luminescent Metallocholate Hydrogels
Supramolecular gels are soft materials consisting of a solid three-dimensional network with noncovalent interactions such as hydrophobic interactions, hydrogen bonding, cation-п, and п- п interactions. Due to their soft, ... -
Multiple Discrete-Continuous Choice Models with Flexible Specification of Constraints, Utility Forms, and Stochastic Distributions: Applications in Travel Behavior Research
Econometric choice models have been widely used in travel behaviour research to understand human activities, time-use, mobility choices, consumption, and related preferences. Most research in this area had focused on ... -
Design, Fabrication and Characterization of ZnO based Thin Film Schottky Diodes and Transistors
The thesis focuses on the development of thin film Schottky diodes and thin film transistors (TFTs) based on ZnO. ZnO has been recognized as a promising candidates for the next generation of transparent and flexible ... -
Refractive-Index-Matched Fluorescent Particle Image Velocimetry for Investigation of Flow in Immersed Granular Materials
Refractive-Index-Matched Fluorescent Particle Image Velocimetry for Investigation of Flow in Immersed Granular Materials The ubiquity of granular materials and their importance in everyday life, industry, and nature make ... -
Recovery Algorithms for planted structures in Semi-random models
For many NP-hard problems, the analysis of best-known approximation algorithms yields “poor” worst-case guarantees. However, using various heuristics, the problems can be solved (to some extent) in real-life instances. ... -
Improved Algorithms for Variants of Bin Packing and Knapsack
We study variants of two classical optimization problems: Bin Packing and Knapsack. Both bin packing and knapsack fall under the regime of "Packing and Covering Problems". In bin packing, we are given a set of input items, ... -
Total Synthesis of Piperidine and Pyrrolidine Alkaloids and Towards the Total Synthesis of Strychnine
Total synthesis of natural products is an important area of contemporary interest in synthetic organic chemistry. Total synthesis of natural products serves as a platform for the development of new synthetic strategies ... -
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 ... -
