Investigations on Online Boundary Variation Techniques for Nearly Constant Switching Frequency Hysteresis Current PWM Controller for Multi-Level Inverter Fed IM Drives
(2018-02-22)
In DC to AC power conversion, voltage source inverters (VSI) based current controllers are usually preferred for today’s high performance AC drive which requires excellent dynamic and steady state performances at different ...
Spatially Correlated Data Accuracy Estimation Models in Wireless Sensor Networks
(2018-02-10)
One of the major applications of wireless sensor networks is to sense accurate and reliable data from the physical environment with or without a priori knowledge of data statistics. To extract accurate data from the physical ...
Content Distribution in Social Groups
(2018-01-29)
We study Social Groups consisting of self-interested inter-connected nodes looking for common content. We can observe Social Groups in various socio-technological networks, such as Cellular Network assisted Device-to-Device ...
Architecture and Design of Wide Band Spectrum Sensing Receiver for Cognitive Radio Systems
(2018-01-03)
To explore spectral opportunities in wideband regime for cognitive radio we need a wideband spectrum sensing receiver. Current wideband receiver architectures need wideband analog to digital converter (ADC) to sample ...
A New Digital Receiver For The Ooty Radio Telescope
(2014-10-16)
A new digital receiver was built for the Ooty Radio Telescope (ORT). This new digital receiver system functionally replaces many systems custom-built for various applications at ORT. The thesis presents the receiver design, ...
