Intelligent Techniques for Monitoring of Integrated Power Systems
(2018-02-10)
Continued increase in system load leading to a reduction in operating margins, as well as the tendency to move towards a deregulated grid with renewable energy sources has increased the vulnerability of the grid to blackouts. ...
Low Switching Frequency Pulse Width Modulation for Induction Motor Drives
(2018-06-11)
Induction motor (IM) drives are employed in a wide range of industries due to low maintenance, improved efficiency and low emissions. Industrial installations of high-power IM drives rated up to 30 MW have been reported. ...
Developmental Studies on Ultra Wide Band Type High Power Electromagnetic Radiating System for Use as an Intentional Electromagnetic Interference Source
(2018-06-13)
The electronic control, instrumentation and communication hardware is becoming more and more compact and faster in operation due to the increased use of large scale integration of semiconductor devices operating at higher ...
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 ...
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 ...
Phase Retrieval and Hilbert Integral Equations – Beyond Minimum-Phase
(2018-07-18)
The Fourier transform (spectrum) of a signal is a complex function and is characterized by the magnitude and phase spectra. Phase retrieval is the reconstruction of the phase spectrum from the measurements of the magnitude ...
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 ...
Discharge Plasma Supported Mariculture and Lignite Waste for NOx Cleaning in Biodiesel Exhaust : Direct and Indirect Methods
(2018-06-18)
One major aspect of environmental pollution affecting human life and climate is air pollution. The harmful pollutants in the air include mostly hydrocarbons, carbon monoxide, carbon dioxide, nitrogen oxides as well as soot ...
Thermal and Electrical Degradation of Resin Impregnated Paper Insulation for High Voltage Transformer Bushings
(2018-01-30)
The overall reliability of a power transformer depends to a great extent on the sound operation of the bushings thereof. In view of its overwhelming advantages, resin impregnated paper (RIP) is acquiring prominence over ...
PWM Techniques for Split-Phase Induction Motor Drive
(2018-02-18)
A split-phase induction motor (SPIM) is obtained by splitting each of the three-phase stator windings of an induction motor into two equal halves. This results in two sets of three-phase windings with a spatial angle ...
