Discovering Frequent Episodes With General Partial Orders
(2013-06-04)
Pattern Discovery, a popular paradigm in data mining refers to a class of techniques that try and extract some unknown or interesting patterns from data. The work carried out in this thesis concerns frequent episode mining, ...
Control Of High Power Wound Field Synchronous Motor Drives - Modelling Of Salient Pole Machine, Field Oriented Control Using VSI, LCI And Hybrid LCI/VSI Converters
(2013-05-02)
This thesis proposes control schemes and converter configurations for high power wound field synchronous motor (WFSM) drives. The model for a salient pole WFSM in any general rotating reference frame is developed which can ...
Power System Stabilizing Controllers - Multi-Machine Systems
(2013-05-02)
Electrical Power System is one of the most complex real time operating systems. It is probably one of the best examples of a large interconnected nonlinear system of varying nature. The system needs to be operated and ...
Active Reactive Induction Motor - A New Solution For Load Commutated SCR-CSI Based High Power Drives
(2013-05-28)
This thesis deals with a new solution for medium voltage drives. Load Commutated Inverter (LCI) fed synchronous motor drive is a popular solution for high power drive applications. Though the induction machine is more ...
Construction Of Equivalent Circuit Of A Single Isolated Transformer Winding From Frequency Response
(2013-06-14)
Frequency response analysis (FRA) of transformers is universally accepted as a highly sensitive tool to detect deformations in its windings. This is evident from the fact that customized commercial equipment (popularly ...
Hierarchical Logcut : A Fast And Efficient Way Of Energy Minimization Via Graph Cuts
(2013-06-10)
Graph cuts have emerged as an important combinatorial optimization tool for many problems in vision. Most of the computer vision problems are discrete labeling problems. For example, in stereopsis, labels represent disparity ...
Planning And Operational Aspects Of Real And Reactive Power In Deregulated Power Systems
(2013-10-09)
The transition of the power sector from vertically integrated utility (VIU) to deregulated system has resulted in reshaping of generation, transmission and distribution components. Some of the objectives of restructuring ...
Geometric And Radiometric Estimation In A Structured-Light 3D Scanner
(2013-10-17)
Measuring 3D surface geometry with precision and accuracy is an important part of many engineering and scientific tasks. 3D Scanning techniques measure surface geometry by estimating the locations of sampled surface points. ...
Solar Powered High Voltage Energization For Vehicular Exhaust Cleaning : A Step Towards Possible Retrofitting In Vehicles
(2013-08-28)
In the last few decades India has advanced socioeconomically due to the rapid growth of industries and automobile sector. This in turn increases the use of fossil fuel and diesel. The atmosphere gets polluted due to the ...
