Multiview Registration Using Rank-Constrained Semide nite Programming
We consider the problem of reconstructing a 3D surface from its multiview scans. Typically, the computational pipeline for this problem has two phases: (I) finding point-to-point correspondences between overlapping scans, ... -
Music And Speech Analysis Using The 'Bach' Scale Filter-Bank
(2009-08-13)The aim of this thesis is to define a perceptual scale for the ‘Time-Frequency’ analysis of music signals. The equal tempered ‘Bach ’ scale is a suitable scale, since it covers most of the genres of music and the error is ... -
Natural frequencies of 3-phase transformer windings.
The equations of the windings of a 3?phase transformer together with the terminal conditions completely specify the electrical behaviour of the windings. However, they are awkward and difficult to solve. These difficulties ... -
Neighborhood based algorithms for network problems
This thesis presents novel techniques for designing efficient algorithms to solve various graph problems, with a focus on both sequential and parallel computation models. The key contributions include: An O(dm)O(dm)O(dm) ... -
A Networked Control Systems Framework for Smart Grids with Integrated Communication
(2018-02-28)Over the last decade, power systems have evolved dramatically around the world, owing to higher demand, stringent requirements on quality and environmental concerns that are becoming increasingly critical. With the ... -
Neural Architectures For Active Contour Modelling And For Pulse-Encoded Shape Recognition
(2014-09-12)An innate desire of many vision researchers IS to unravel the mystery of human visual perception Such an endeavor, even ~f it were not wholly successful, is expected to yield byproducts of considerable significance to ... -
Neural networks for invariant recognition of 2-D objects
This thesis studies the problem of translation-, rotation- and size-invariant recognition of two-dimensional objects. This problem can be framed as follows: Given (i) a set of object descriptions in terms of either global ... -
Neural Representation Learning for Speech and Audio Signals
Representation learning is the branch of machine learning consisting of techniques that are capable of automatically discovering meaningful representations from raw data for efficient information extraction. In recent ... -
New Algorithms for Some Economic Dispatch Problems
(2018-01-01)An electric power system consists of several generating stations which cater to the load demands of various regions. The prime function of any generating utility is to optimally schedule the real power output of its ... -
A New Family Of Soft Transition DC-DC Converters
(2009-09-10)Switched mode power supplies (SMPS) have found wide spread acceptance in all power processing applications. The design demand is moving towards higher power densities. For reduction in size and weight, it is imperative to ... -
No/Nox Removal In Diesel Engine Exhaust Under Different Energizations And Reactor Configurations
(2010-06-09)In India, with the increase in the number of industries and vehicles the environment is getting more and more polluted. More than industries it is the rapid growth of vehicles which causes serious environmental crisis in ... -
Non-contact Breathing and Heartbeat signals monitoring using FMCW radar
Non-contact breathing and heartbeat signals monitoring are the tasks of extracting them without contact sensors. It became even more critical in COVID 19, and hence it is crucial to estimate them correctly. FMCW (Frequency ... -
A Novel Approach for Tuning of Power System Stabilizer Using Genetic Algorithm
(Indian Institute of Science, 2005-02-11)The problem of dynamic stability of power system has challenged power system engineers since over three decades now. In a generator, the electromechanical coupling between the rotor and the rest of the system causes it to ... -
A Novel Generalized Analytical Framework to Diagnose True Radial and Axial Displacements in an Actual Transformer Winding
(2017-12-02)Frequency response analysis (FRA) has emerged as the de-facto industry standard condition-monitoring tool to assess mechanical integrity of transformer windings during its service life. It the prerequisite detection ... -
Novel Methods For Estimation Of Static Nonlinearity Of High-Speed High-Resolution Waveform Digitizers
(2011-01-20)Analog-to-digital converter (ADC) is the main workhorse in a digital waveform recorder. Strictly speaking, an ADC is supposed to perform uniformly, irrespective of the characteristics of the signal to be acquired. However, ... -
A Novel Passive Regenerative Snubber for the Phase-Shifted Full-Bridge Converter: Analysis, Design and Experimental Verification
The development of Wide Bandgap (WBG) devices has enabled power electronic converters to operate at much higher frequencies, voltages and high power. Working at a higher switching frequency minimises the size of magnetics ...
