Enhancement of Small Signal Stability in Power Systems: Novel Approaches
The modern power system is a highly nonlinear system that operates in a constantly changing environment. Power system, need to maintain more or less flat voltage profile across the grid and maintain stability for small and ... -
Enhancing THC/NOX removal efficiency in diesel exhaust through catalyzing industrial wastes in the presence of electric discharge plasma
The consistent rise in air quality index in various cities has risen a worldwide concern toward the critical situation of air pollution and climate change. Despite the implementation of stringent regulations, the usage of ... -
Estimating probabilities of rare events in regenerative systems via importance sampling
In the high-speed networks currently being designed, the probability of packet loss required is very low, while the closed-form expressions for these events are usually not available. Therefore, one needs to estimate these ... -
Estimation of flashovers in the EHV/UHV lines on the east coast due to lightning produced by the Bay of Bengal cyclones
Electric Power is imperative for the modern world. The quality and reliability of the power supply can be impaired by several factors. Lightning is one such natural threat that disrupts the continuity of supply and can ... -
Excitation dynamics in GaAs quantum wells
The dynamics of excitons is studied using time?resolved photoluminescence. We deduce experimentally, for the first time, the intrinsic homogeneous linewidth of free excitons in GaAs quantum wells. The scattering rate of ... -
Experiential Sampling For Object Detection In Video
(2010-08-26)The problem of object detection deals with determining whether an instance of a given class of object is present or not. There are robust, supervised learning based algorithms available for object detection in an image. ... -
Experimental and Theoretical Investigations on High Voltage Polymeric Insulators
High Voltage Ceramic and glass Insulators have been widely used by various transmission and distribution utilities for several decades across the globe. Recently composite or silicone rubber insulators have evolved and ... -
Experimental Investigations on Switching Behavior of Locomotive Traction-grade IGBTs over Wide Operating Conditions
Insulated gate bipolar transistors (IGBTs) are the dominant power semiconductor devices in high power applications, such as, locomotive traction and megawatt-level renewable energy systems. Power electronic converters in ... -
Experimental Studies on Acoustic Noise Emitted by Induction Motor Drives Operated with Different Pulse-Width Modulation Schemes
(2018-08-13)Voltage source inverter (VSI) fed induction motors are increasingly used in industrial and transportation applications as variable speed drives. However, VSIs generate non-sinusoidal voltages and hence result in harmonic ... -
Explicit Segmentation Of Speech For Indian Languages
(2010-07-02)Speech segmentation is the process of identifying the boundaries between words, syllables or phones in the recorded waveforms of spoken natural languages. The lowest level of speech segmentation is the breakup and ... -
Face Recognition in Unconstrained Environment
The goal of computer vision is to provide the ability to machines to understand image data and infer the useful information from it. The inferences highly depend on the quality of the image data. But in many real-world ... -
Fast adaptive multipole-algorithm for scattering from inhomogeneous dielectric cylinders of arbitrary cross-section
The work reported in this thesis is concerned with the rapid solution of electromagnetic scattering problems involving inhomogeneous dielectric cylinders of arbitrary cross?section. In particular, attention is focused on ... -

Fast and Robust Biomedical Image Reconstruction from Nonuniform Samples
We consider the problem of reconstructing images from non-uniformly under-sampled spatial point measurements with emphasis on robustness to noise. The computational methods that deals with this problem are known as ... -
A Fast Constant-Time Approximation for Locally Adaptive Bilateral Filtering
Smoothing is a fundamental task in low-level image processing that is used to suppress irrelevant details while preserving salient image structures. The simplest smoothing mechanism is to average neighboring pixels using ... -
Fast High-Dimensional Filtering
Smoothing (diffusion) is a fundamental task in low-level vision and image processing. In the context of natural images, where edges (sharp discontinuities) play an important psychovisual role, the smoothing process needs ... -
Fast total variation minimizing image restoration under mixed Poisson-Gaussian noise
Image acquisition in many biomedical imaging modalities is corrupted by Poisson noise followed by additive Gaussian noise. Maximum Likelihood Estimation (MLE) based restoration methods that use the exact Likelihood ... -
Fault Creation, Detection and Classification Systems for Modern Power Grids
The power grid is changing with the exponentially growing penetration of inverter-based resources (IBRs). Keeping the power grid stable, reliable, and secure, and delivering quality power has become increasingly important ...
