Itaconate Based Novel Amphiphilic Polymer Architectures
Amphiphiles are natural or synthetic molecules consisting of hydrophilic polar head group and hydrophobic non-polar hydrocarbon tail. Beyond a certain concentration, known as critical micellar concentration (CMC), amphiphilic ... -
Electronic Photonic Circuit Design for RF Transceiver
RF over fibre (RoF) based communication system combines features of mm-wave and optical fibre communication. The RoF-based system has the advantage of both optical fibre systems (such as high bandwidth, signal transparency, ... -
Mutational sensitivity of CcdB mutants in their native operonic context
Determining the precise effects of thousands of point mutants on protein structure, stability, and activity is a challenging task. Chapter 1 introduces how next-generation sequencing technologies exploit phenotypic screens ... -
Unravelling the functional role of Arf-like GTPases 14 and 15 in mammalian cells
Small G-proteins of Arf-like (Arl) GTPase subfamily are shown to regulate several cellular processes including intracellular trafficking, cytoskeletal organization, organelle biogenesis, cell adhesion and migration. Around ... -
An electromagnetically actuated mesoscale ball and socket joint for applications in 3-D metrology and electrical characterization
Micro-robotics is concerned with development of robotic systems to manipulate micro-meter sized objects. To develop functional micro-robotic manipulators, it is necessary to develop joints that possess large motion range ... -
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
