Risk Estimation Strategies for Speech Signal Denoising
In automatic speech recognition (ASR) systems, the recognition performance is severely affected by noise in the input speech signal [2]. One can improve the performance of ASR systems in noisy environments by denoising ... -
Production of taxol from Lasiodiplodia theobromae and biochemical characterization of its 10-deacetylbaccatin III-10-O-acetyltransferase enzyme and evaluation of anticancer activity of enzymatically synthesized baccatin III
Taxol (paclitaxel) originally identified from the inner bark of Taxus brevifolia, is a clinically approved anticancer drug for the treatment of various kinds of cancer, particularly ovarian cancer, breast cancer and Kaposi's ... -
Structural Correlates of Related Contextual Learning in Retrosplenial Cortex
The discovery of dendritic spines by Santiago Ramón y Cajal is one of the most important chapters in the history of neuroscience. Apart from establishing the neuron doctrine, it presented dendritic spines as the information ... -
Development of Graphene Based Sensors for Human Physiological Monitoring and Vacuum Measurement
Nanomaterials have emerged as a remarkable class of materials in recent years owing to their excellent electrical, chemical, and physical properties. The first two-dimensional (2D) material to be discovered, graphene, has ... -
Self-powered Broadband and Ultrafast Photoresponse using InN and InGaN grown on AlN/Si (111) by Plasma-assisted Molecular Beam Epitaxy
Group III-nitride semiconductors have enabled revolution in solid-state lighting and high-power/high-frequency electronics. Now-a-days, III-nitride based photodetectors are of great importance because of their various ... -
Subsurface Profiling of Shallow Bedrock Sites by Integrated Approach and Site-specific 2d Site Response Analysis
Estimation of reliable site effects and amplifications are important for seismic design. There are several 1D and 2D large scale site response analyses were reported in the literature and very limited shallow bedrock small ... -
Biodiesel from Estuarine Microalgae - Diatoms
Rapidly depleting fossil fuel reserves with the burgeoning demand, associated escalating GHG footprint, and changes in the climate necessitated the exploration of alternate sustainable energy resources that are renewable, ... -
Hyperspectral and Spectropolarimetric Instrumentation for the Solar Atmosphere
The Sun is the closest star whose surface can be resolved to great a detail. Understanding the working of Sun helps in understanding a large fraction of stellar system as it falls under the spectral class G2V which is ... -
A Unified Framework For Micromechanical Damage Modeling In Laminated Polymer Matrix Composites
A unified numerical framework for progressive damage analysis in polymer matrix composite (PMC) laminates has been developed by explicitly accounting for damage progression at the micro-level. A three-dimensional repeating ... -
Stabilized finite element schemes for computations of viscoelastic free-surface and two-phase flows
Viscoelastic flows can be found in a wide range of industrial and commercial applications such as enhanced oil recovery, pesticide deposition, medicinal/pharmaceutical sprays, drug delivery, injection molding, polymer ... -
Adjacent Independent Row (Air) Matrices and Index Coding
An index coding problem, comprises a transmitter that has a set of independent messages and a set of receivers. Each receiver knows a subset of messages, called its side-information, and demands another subset of messages, ... -
Structural Reliability Estimation Using Markov Chain Splitting and Girsanov’s Transformation Based Methods
The work reported in this thesis is in the area of Monte Carlo simulation based methods for structural reliability estimation with special focus on strategies to reduce sampling variance of the estimator for the probability ... -
Water Market for Efficient Management of Water Resources in India
India sustains nearly 17% of the world's population but with only 4 % of global water resources. In India, the water sector faces enormous pressure due to increased demand resulting from population growth, industrialisation, ... -
Carbon nanomaterials for energy and environmental applications
Environmental pollution and energy storage are two important issues in the modern day society. In this regard, Carbon nanomaterials have attained immense importance, due to their high surface area and electrical conductivity ... -
Handling Overloads with Social Consistency
Cloud computing applications have dynamic workloads, and they often observe spikes in the incoming traffic which might result in system overloads. System overloads are generally handled by various load balancing techniques ... -
Correlation-aware Splitting Algorithms for Opportunistic Selection
Opportunistic selection is a key technique to improve the performance of wireless systems. In it, the best set of users among the available ones is selected on the basis of their instantaneous channel gains or local ... -
Molecular Dynamics simulations reveal the role of membrane cholesterol in the pore forming pathway of Cytolysin A
We investigate the interactions of pore-forming toxins (PFTs) with cholesterol-rich membranes through atomistic molecular dynamics simulations. The PFT of interest is Cytolysin A (ClyA or HlyE). Cytolysin A (ClyA), an ... -
Optimization of Traversal Queries on Distributed Graph Stores
In this era of Big Data Analytics, much of the semi-structured data has inherent interconnectivity between representative entities. These are increasingly being modeled as property graphs because of the semantic advantages ... -
Interlinkages, Innovation, Internationalization and Economic Performance of Manufacturing SMEs in Bangalore
Small and Medium Enterprises (SMEs) occupy a place of strategic significance in the global economy (including India) due to their significant contributions in terms of employment generation, exports, income creation, and ...
