Studies on Internal Reforming Solid Oxide Fuel Cell
Renewable energy becomes inevitable for future energy needs. Accordingly, researchers are exploring possible alternatives to conventional fuel based internal combustion engines. In recent years, Bio-fuel (methane/ethanol) ... -
Effect of Copper on Strength of Super 304H Austenitic Stainless Steel
Super 304H is a copper-containing austenitic stainless steel with potential applications in advanced thermal power plants owing to its superior corrosion, oxidation, creep resistances and cost affordability. The addition ... -
Optimal Relay Selection in Interference-Constrained Underlay Cooperative Cognitive Radio
Cognitive radio (CR) promises to significantly improve the utilization of scarce wireless spectrum. In the underlay mode of CR, which is the focus of the thesis, a secondary user (SU) can simultaneously transmit on the ... -
Theta-band Spectral Selectivity and Gamma-range Coincidence Detection in Spike Initiation Dynamics of Hippocampal Pyramidal Neurons
In the pursuit to understand information processing in the brain, a general question that is often posed is: What is the neuron encoding? This is addressed by assessing feature selectivity in sensory neurons, which informs ... -
Isolation, Structure Elucidation and Functional Characterization of a Novel Cytotoxic Secondary Metabolite Phomafuranone, 2-Hydroxy-2, 4-dimethyl-5-[-1-propen-1-yl]-3(2H)-furanone, from Phoma tropica an Endophytic Fungus Isolated from Mappia foetida.
Cancer has become the leading disease-related cause of death in the human population. For example, in the United States, cancer is the second leading cause of death behind cardiovascular disease, and it is projected that ... -
Site-selective C-H Functionalization using Directing Group Strategy via C-H Bond Activation
The thesis entitled “Site-selective C-H Functionalization using Directing Group Strategy via C-H Bond Activation” is divided into two sections. Section A, is presented in four chapters, comprising the work on the aromatic ... -
Nonlinear Charge Transport and Photo-Physical Studies in Conjugated Polymers (P3meT, P3HT) and their Hybrid Composites with Silver Sulfide Quantum Dots
Organic semiconductors have been investigated as an emerging class of materials for their viable applications in electronics. Despite considerable improvement in device properties, a better understanding of the nature of ... -
Understanding the Biology of Heat Shock Protein 90 in Opportunistic Fungal Pathogens
Heat shock protein 90 is one of the most abundant and evolutionary conserved class of molecular chaperones present throughout the biological kingdom. It is a specialist chaperone as its function extends beyond protein ... -
Fully Solution Processed Flash Memory
The field of advanced solution processed spin-coated electronics has rapidly expanded over the last few decades towards the development of low-cost, large area and low power consumer electronics for the design of ... -
Deciphering Functions & Interactions of Fission Yeast Splicing Factor SpSlu7 Relevant to Constitutive & Alternative Splicing
The fission yeast genome with abundant multi-intronic transcripts, degenerate splice signals and presence of alternative splicing machinery is an attractive unicellular fungal model to investigate splice-site recognition ... -
Structure, Dynamics and Optical Properties of Organic-Inorganic Hybrid Perovskites
Organic-inorganic hybrid perovskites have emerged as promising photovoltaic materials in the last few years, with the possibility of easy, solution synthesis. In this thesis, we have investigated some intrinsic material ... -
Design of Communication Systems with Energy Harvesting Transmitters and Receivers
An energy harvesting node (EHN) operates using the energy harvested from the environment, e.g., solar, piezoelectric and radio frequency, which presents the tantalizing possibility of perpetually operating of sensor nodes. ... -
Blocker-tolerant Receiver Design Suitable for Software-defined and Cognitive Radio Applications
The ever growing demand for higher data rates and the heavy usage of wireless communication devices have created frequency congestion on certain bands of the radio spectrum. The push has been towards new standards that can ... -
Information-rich Sampling of Time-varying Signals
Confrontation with signal non-stationarity is a rule rather than an exception in the analysis of natural signals, such as speech, animal vocalization, music, bio-medical, atmospheric, ans seismic signals. Interestingly, ... -
Sustained Competitive Advantage : Strategic HRM Initiatives, Antecedents and Consequences in Indian Context
In the last two decades, researchers have argued that human resources may be seen as a source of sustained competitive advantage. In such a context, it is important to examine some new and emerging HR roles and practices ... -
Heterogeneity Aware Shared DRAM Cache for Integrated Heterogeneous Architectures
Integrated Heterogeneous System (IHS) processors pack throughput-oriented GPGPUs along-side latency-oriented CPUs on the same die sharing certain resources, e.g., shared last level cache, network-on-chip (NoC), and the ... -
Synthesis of Thermally Stable Catalysts for Methane Reforming and CO Abatement
The global energy consumption is estimated to reach around 262×1012 kWh/year by 2050 for 9 billion people. It is a challenge to meet global energy requirement via clean fuel (hydrogen) and by reducing/utilizing the CO2 ... -
