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 ...
Wavelet Based Algorithms For Spike Detection In Micro Electrode Array Recordings
(2010-07-13)
In this work, the problem of detecting neuronal spikes or action potentials (AP) in noisy recordings from a Microelectrode Array (MEA) is investigated. In particular, the spike detection algorithms should be less complex ...
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 ...
Optimum Savitzky-Golay Filtering for Signal Estimation
(2018-03-21)
Motivated by the classic works of Charles M. Stein, we focus on developing risk-estimation frameworks for denoising problems in both one-and two-dimensions. We assume a standard additive noise model, and formulate the ...
Hall-Effect Current Sensors for Power Electronic Applications : Design and Performance Validation
(2018-03-09)
Closed loop Hall-effect current sensors used in power electronic applications require high bandwidth and small transient errors. For this, the behaviour of a closed loop Hall-e ect current sensor is modeled. Analytical ...
Reactive Power Co-ordination in Grid Connected Wind Farms for Voltage Stability Enchancement
(2018-04-05)
Recent decades have witnessed a significant increment in power contribution from wind generators. This increment in penetration requires power engineers to tackle multi-fold challenges concerning operational and stability ...
Lightning Threat to Cables on Tall Towers and the Question of Electrical Isolation
(2018-04-23)
Electromagnetic effects of lightning currents during a direct hit to tall communication towers, other instrumented towers and chimneys can be hazardous to associated cables, as well as, electrical and electronics systems. ...
