Excited State Intramolecular Charge Transfer: Ultrafast Electronic and Vibrational Spectroscopic Study
This thesis incorporates the understanding of the ultrafast excited state photoinduced intramolecular charge transfer (ICT) process in liquid phase. The molecular systems are studied by employing Ultrafast Raman Loss ... -
Engineering of Nanomaterials: Application in Antibacterial Activity, Bio-Analyte Detection and Environmental Remediation
Infectious diseases caused by pathogenic bacteria are creating a global health problem. In the recent report of World Health Organization (WHO), it has been mentioned that around 7 lacks people are dying each year worldwide ... -
Development and Applications of Portable Raman Spectroscopy Combined with Artificial Intelligence for Biomedicine
Currently, the global spectroscopic community is investigating the suitability of vibrational spectroscopy methods for point-of-care testing, histopathology, and rapid in-vivo biomedical diagnostics. Although Raman ... -
A multi-physics-based modelling approach to predict mechanical and thermo-mechanical behaviour of cementitious composite in a multi-scale framework
Concrete is a heterogeneous material whose constituents (e.g., cement paste, aggregate etc.) range from a characteristic length-scale dimension of a nanometre to a metre. Owing to the heterogeneity of concrete and the ... -
Local Projection Stabilization Methods for the Oseen Problem
Finite element approximation of fluid flow problems with dominant convection exhibit spurious oscillations. To eliminate these nonphysical oscillations one needs to incorporate stabilizations that can curb the effect of ... -
Design and Development of Implantable Electrode Arrays for Recording Signals from Rat’s Brain
Seizure is a neurological disorder due to abnormal, excessive, and hypersynchronous discharges from an aggregate of central nervous system neurons. Epilepsy describes the clinical phenomena of a condition of recurrent and ... -
On the development of sensible heat storage for concentrated solar power applications: Thermo-fluid management and materials
Sensible heat storages have extensive use in thermal energy deployment, including concentrated solar power (CSP) applications. Usually, CSP pants demand various techno-economic features in sensible heat storage, such as ... -
Identifying Bacterial Species, Detecting Antibiotic Resistance and Susceptibilities in Clinical Samples Using Raman Spectroscopy
Over the past few decades, Raman spectroscopy has found enormous applications in biology and medicine. Raman micro-spectroscopy is highly sensitive to the structure and composition of molecules and their surrounding moieties ... -
Structural and Thermoelectric Studies of Sb2Te3 and Bi2Te3 Based Chalcogenide Alloys and Nanocomposites
Thermoelectricity is one of the potential solutions for the rapidly increasing energy demand. Thermoelectric generators can turn waste heat into usable energy. Due to their effectiveness in the 300 K to 500 K temperature ... -
Fast and Compact Voltage Equalizer for Satellite Applications
Lithium-ion batteries have now become an essential constituent of the Electrical Power System of solar-powered satellites due to their high energy density, wider operating temperature range , and better radiation tolerance. ... -
Design and Development of an Intubation Catheter Integrated with MEMS-based Sensors for Central Airway Obstruction
Airway pathology leads to alteration in fluid flow, tissue biomechanics, and loss of patency. To address this clinical challenge, we developed an intraoperative tool to locate the site of obstruction, characterize tracheal ... -
Investigation of strongly correlated paramagnetic state at sub-Kelvin regime for S ≥ 1/2 systems: Role of disorder and dimensionality
A magnetic system usually orders ferro- or anti-ferromagnetically at temperatures comparable to interaction strength between the spins. Moreover, an interacting spin system tends to order with the increase of dimensionality ... -
Wide Area Measurement Based Cyber-Attack Resilient Breaker Failure Protection Scheme
Breaker Failure Protection(BFP) is a backup protection that comes into action when the primary protection schemes are unable to clear the fault. In power systems, every component has a redundant version to avoid failures. ... -
Optimization of Wastewater Treatment Process in a Bioreactor Through Hydrodynamic-biokinetic Modeling and Experimental Studies
Membrane bioreactor has emerged as one of the leading technologies for treating municipal and industrial wastewater due to its efficiency in producing high-quality effluents. One of the significant challenges in bioreactors ... -
Interpolation of Digital Elevation Models using Generative Adversarial Networks
A digital elevation model (DEM) is a three-dimensional representation of elevation data of a terrain such as a terrestrial terrain acquired by a reconnaissance aircraft or a lunar terrain acquired using a Chandrayaan rover. ... -
Parietal and prefrontal control of distinct components of attention
In this thesis, we investigate behavioural mechanisms and neural substrates of distinct components of endogenous spatial attention. Endogenous attention facilitates neural processing of the selected stimulus through one ... -
Thermochemical conversion of biomass – single particle and packed bed: Experimental and Numerical Studies
The current work uses experimental and numerical techniques to analyze the thermochemical conversion of a single biomass particle exposed to various reactive environments – varying temperatures and O2, CO2 and H2O ... -
Inducing Constraints in Paraphrase Generation and Consistency in Paraphrase Detection
Deep learning models typically require a large volume of data. Manual curation of datasets is time-consuming and limited by imagination. As a result, natural language generation (NLG) has been employed to automate the ... -
