Accurate Estimation of Frequency and Phasor for Wide Area Monitoring and Control
Traditionally, monitoring and control functions in large power systems were based on measurements obtained locally. While small disturbances have their impact con ned locally to the area of disturbance, large disturbances ... -
Behavior of Distance Relay Characteristics on Interconnecting Lines Fed From Wind Farms
(2018-05-14)Distance relays due to their selectivity and operating speed are used in HV/EHV line protection. The dynamic nature of Mho characteristic, which happens to be most primitive technique in line protection implemented with ... -
Discharge Plasma based NOx Abatement in Engine Exhaust Assisted by Industry Wastes : A Parametric Evaluation with Diesel Fuels and Corona Electrodes
Diesel engines contribute to a large percentage of oxides of nitrogen (NOx) emission in the atmosphere. The NOx primarily consists of nitric oxide (NO) and nitrogen dioxide (NO2). With depleting fossil fuel supplies ... -
Dynamic Headpose Classification and Video Retargeting with Human Attention
(2018-07-14)Over the years, extensive research has been devoted to the study of people's head pose due to its relevance in security, human-computer interaction, advertising as well as cognitive, neuro and behavioural psychology. One ... -
Effective Characterization of Sequence Data through Frequent Episodes
(2018-08-14)Pattern discovery is an important area of data mining referring to a class of techniques designed for the extraction of interesting patterns from the data. A pattern is some kind of a local structure that captures correlations ... -
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 ... -
Geometric Calibration and Shape Refinement for 3D Reconstruction
This thesis is a contribution towards the methods of 3D reconstruction in computer vision. Most of the 3D reconstruction methods are based on either the principle of triangulation or the principle of photometry. In this ... -
Integrated CM Filter for Single-Phase and Three-Phase PWM Rectifiers
(2018-08-11)The use of insulated-gate bipolar transistor (IGBT)-based power converters is increasing exponentially. This is due to high performance of these devices in terms of efficiency and switching speed. However, due to the ... -
Lightning Shielding Failure Analysis of Ultra High Voltage Power Transmission Lines
(2018-08-14)In India, the natural energy resources (thermal and hydro) are unevenly distributed and are mostly present in the remote areas and the load centers are distributed across various regions of the country. Therefore high ... -
Modeling and Analysis of Grid Connected Variable Speed Wind Generators
(2018-08-13)The growing demand for power and increased environmental concerns gave an impetus to the growth of clean and renewable energy sources like wind, solar etc. There is a remarkable increase in the penetration of wind energy ... -
Motion Estimation From Moments Of Projection Data For Dynamic CT
(2016-09-15)In X-ray computed tomography, motion of the object (breathing, for example) while X-ray projections are acquired for tomographic reconstruction leads to mo- tion artifacts in the reconstructed image. Object motion (such ... -
On Maximizing The Performance Of The Bilateral Filter For Image Denoising
(2017-07-07)We address the problem of image denoising for additive white Gaussian noise (AWGN), Poisson noise, and Chi-squared noise scenarios. Thermal noise in electronic circuitry in camera hardware can be modeled as AWGN. Poisson ... -
Reactive Power Planning And Operation of Power Systems with Wind Farms for Voltage Stability Improvement
(2017-09-23)In recent years, the electric power industry around the world is changing continuously due to transformation from regulated market structure to deregulated market structure. The main aim of the transformation of electric ... -
Savitzky-Golay Filters and Application to Image and Signal Denoising
(2018-07-18)We explore the applicability of local polynomial approximation of signals for noise suppression. In the context of data regression, Savitzky and Golay showed that least-squares approximation of data with a polynomial of ... -
Small Signal Stability Analysis of a Power System with a Grid Connected Wind Powered Permanent Magnet Synchronous Generator (PMSG)
(2018-07-18)Small signal oscillation has been always a major concern in the operation of power systems. In a generator, the electromechanical coupling between the rotor and the rest of the system causes it to behave in a manner similar ... -
Trajectory-based Descriptors for Action Recognition in Real-world Videos
(2018-07-30)This thesis explores motion trajectory-based approaches to recognize human actions in real-world, unconstrained videos. Recognizing actions is an important task in applications such as video retrieval, surveillance, ...
