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 ...
Algorithms for Adjusted Load Flow Solutions using the Complementarity Principle
The state of a given power system i.e. voltage magnitudes and angles at all the buses can be computed using the Newton-Raphson Load Flow (NRLF) method when active power and reactive power loads are specified at all the ...
Power Electronic Technologies for Medium and High Power High Voltage Power Supplies
The performance of systems used in various high voltage applications depend majorly on the output voltage ripple of High Voltage Power Supplies (HVPS). One of the failure mode of microwave tube (MWT) commonly used in these ...
Discriminative Descriptors for Unconstrained Face and Object Recognition
Face and object recognition is a challenging problem in the field of computer vision. It deals with identifying faces or objects form an image or video. Due to its numerous applications in biometrics, security, multimedia ...
Electromagnetic Properties of Carbon Based Polymer Nanocomposites for Shielding, Chaffing and Camouflage Applications
High conductivity is a prerequisite for any material for it to be used in the field of electromagnetics. Metals like copper and aluminium are used for a variety of electromagnetic (EM) applications in industries like ...
Dual Comparison One Cycle Control for Grid Connected Converters
Grid connected converters are widely used as front end rectifiers, interface between renewable energy and grid, and power quality applications. Popular control techniques to generate gating signals for active devices, ...
Analysis, Control and Applications of Active Phase Converters for Single-Phase Power Grids
Single-phase distribution is a preferred approach for setting up microgrids or supplying
power to rural and remote locations due to its lower infrastructure costs when compared
to a three-phase grid. On the other hand, ...
Pronunciation assessment and semi-supervised feedback prediction for spoken English tutoring
Spoken English pronunciation quality is often influenced by the nativity of a learner, for whom English is the second language. Typically, the pronunciation quality of a learner depends on the degree of the following four ...
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 ...
Content-Based Texture Analysis and Synthesis for Low Bit-Rate Video Coding Using Perceptual Models
Determining perceptually irrelevant and redundant information from human point of view is one of the fundamental problems today that is limiting the performance of current video compression algorithms. The performance of ...
