Moisture Aided Degradation of Oil Impregnated Paper Insulation in Power Transformers
(2018-01-03)
Transformers are the most expensive and critical asset in any electrical power network. Their failure results in long interruption of power supply with consequent loss of reliability and revenue. Understanding and detection ...
Transient Analysis of EHV/UHV Transmission Systems for Improved Protection Schemes
(2018-03-07)
Ever increasing demand for electricity, exploitation of large hydro and nuclear power at remote location has led to power evacuation by long EHV/UHV transmission systems. This thesis concentrates on transient analysis of ...
Transient Lightning Electromagnetic Field Coupling With An Airborne Vehicle In The Presence Of Its Conducting Exhaust Plume
(2010-09-03)
The indirect effects of a nearby lightning strike on an airborne vehicle with its long trailing conducting plume is not well understood. Since airborne vehicles and its payload are expensive, their loss as a result of ...
Algorithms for processing polarization-rich optical imaging data
(Indian Institute of Science, 2005-04-13)
This work mainly focuses on signal processing issues related to continuous-wave, polarization-based direct imaging schemes. Here, we present a mathematical framework to analyze the performance of the Polarization Difference ...
An Algorithmic Approach To Some Matrix Equivalence Problems
(2010-06-09)
The analysis of similarity of matrices over fields, as well as integral domains which are not fields, is a classical problem in Linear Algebra and has received considerable attention. A related problem is that of simultaneous ...
A Study Of Vacuum Interrupter Performance Based On The Characteristics Of Arc Voltage Developed During Current Interruption
(2010-06-09)
A vacuum interrupter is a switching device used in vacuum circuit breakers, which are widely employed in medium voltage circuits for interrupting the short-circuit fault currents. The vacuum interrupter is the chamber in ...
Terminal Connection And System Function For Making Sweep Frequency Response Measurements On Transformers
(2010-07-08)
Sweep Frequency Response (SFR) measurement on a transformer is a low voltage, offline exercise. So, it virtually permits determination of any network or system function, by imposing any desired terminal condition for the ...
Efficient Design of Embedded Data Acquisition Systems Based on Smart Sampling
(2018-05-10)
Data acquisition from multiple analog channels is an important function in many embedded devices used in avionics, medical electronics, robotics and space applications. It is desirable to engineer these systems to reduce ...
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 ...
