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. ...
Control Strategies for Seamless Transition between Grid Connected and Islanded Modes in Microgrids
(2018-06-14)
The popularity of distributed generating (DG) sources have been increasing over the past few years. With the increasing penetration of these DGs, the concept of micro grid is becoming popular. A micro grid is a small power ...
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 ...
Operation of Three Phase Four Wire Grid Connected VSI Under Non-Ideal Conditions
(2018-04-12)
The necessity to incorporate renewable energy systems into existing electric power grid and need of efficient utilization of electrical energy are growing every day. A shunt connected Voltage Source Inverter(VSI) capable ...
Trajectory-based Descriptors for Action Recognition in Real-world Videos
(2018-07-30)
This thesis explores motion trajectory-based approaches to recognize human actions in
real-world, unconstrained videos. Recognizing actions is an important task in applications
such as video retrieval, surveillance, ...
Effective Characterization of Sequence Data through Frequent Episodes
(2018-08-14)
Pattern discovery is an important area of data mining referring to a class of techniques designed for the extraction of interesting patterns from the data. A pattern is some kind of a local structure that captures correlations ...
