Motion Estimation From Moments Of Projection Data For Dynamic CT
(2016-09-15)
In X-ray computed tomography, motion of the object (breathing, for example)
while X-ray projections are acquired for tomographic reconstruction leads to mo-
tion artifacts in the reconstructed image. Object motion (such ...
Dimensioning Of Corona Control Rings For EHV/UHV Line Hardware And Substations
(2015-07-13)
High voltage (EHV and UHV) transmission facilitates transfer of large amount of power over long distances. However, due to the inherent geometry, the line and substation hardware of EHV and UHV class generate high electric ...
Dead-Time Induced Oscillations in Voltage Source Inverter-Fed Induction Motor Drives
(2017-12-07)
The inverter dead-time is integral to the safety of a voltage source inverter (VSI). Dead-time is introduced between the complementary gating signals of the top and bottom switches in each VSI leg to prevent shoot-through ...
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 ...
Modeling and Analysis of Grid Connected Variable Speed Wind Generators
(2018-08-13)
The growing demand for power and increased environmental concerns gave an impetus to the growth of clean and renewable energy sources like wind, solar etc. There is a remarkable increase in the penetration of wind energy ...
Integrated CM Filter for Single-Phase and Three-Phase PWM Rectifiers
(2018-08-11)
The use of insulated-gate bipolar transistor (IGBT)-based power converters is increasing exponentially. This is due to high performance of these devices in terms of efficiency and switching speed. However, due to the ...
Experimental Studies on Acoustic Noise Emitted by Induction Motor Drives Operated with Different Pulse-Width Modulation Schemes
(2018-08-13)
Voltage source inverter (VSI) fed induction motors are increasingly used in industrial and transportation applications as variable speed drives. However, VSIs generate non-sinusoidal voltages and hence result in harmonic ...
Lightning Shielding Failure Analysis of Ultra High Voltage Power Transmission Lines
(2018-08-14)
In India, the natural energy resources (thermal and hydro) are unevenly distributed and are mostly present in the remote areas and the load centers are distributed across various regions of the country. Therefore high ...
On a Divide-and-Conquer Approach for Sensor Network Localization
(2018-08-20)
Advancement of micro-electro-mechanics and wireless communication have proliferated the deployment of large-scale wireless sensor networks. Due to cost, size and power constraints, at most a few sensor nodes can be equipped ...
