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 ...
Modulation of Power Electronic Converter Fed Split-phase Induction Machine Drive
Induction machine (IM) is the workhorse of several industries due to its low cost and minimal
maintenance. Power electronic converters play a major role in driving IMs which give
better
flexibility in these applications. ...
Modeling, Characterization, Control and Design of Switched Reluctance Machines
Switched reluctance machines (SRM) are permanent magnet free, and have a simple rotor construction with no current carrying parts. These are particularly suitable for high-temperature and high-speed applications. However, ...
Kernel-Based Image Filtering: Fast Algorithms and Applications
Image filtering is a fundamental preprocessing task in computer vision and image processing.
Various linear and nonlinear filters are routinely used for enhancement, upsampling, sharpening,
reconstruction, etc. The focus ...
Devanagari Online Handwritten Character Recognition
In this thesis, a classifier based on local sub-unit level and global character level representations
of a character, using stroke direction and order variations independent features, is developed
for recognition of ...
AlGaN/GaN Heterojunction Based Hall Sensors for Magnetic Field Sensing over Wide Temperature Range
Hall sensor has proved to be an attractive solution for sensing requirements in electric
machines for direct measurement of fields or indirect estimation of physical quantities
such as current, speed and torque. Current ...
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 ...
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 ...
