Content Dissemination in Mobile Ad Hoc Networks
(2018-06-26)
In this thesis, we are concerned with content dissemination in mobile ad hoc networks. The scope of content dissemination is limited by network capacity, and sometimes the price to be paid for securing faster delivery. In ...
A Modified Sum-Product Algorithm over Graphs with Short Cycles
(2018-07-18)
We investigate into the limitations of the sum-product algorithm for binary low density parity check (LDPC) codes having isolated short cycles. Independence assumption among messages passed, assumed reasonable in all ...
Bond Graph Model Of A Generalised Multiphase Electromagnetic Device With Magnetic Non-idealities
(2013-09-04)
The electromagnetic machines like the dc, induction, synchronous motor/generator and the transformer have an energy flow framework that is similar. All these machines deal with electrical energy in the electrical domain ...
Investigation On Dodecagonal Multilevel Voltage Space Vector Structures By Cascading Flying Capacitor And Floating H-Bridge Cells For Medium Voltage IM Drives
(2017-02-16)
In high-power electric drives, multilevel inverters are generally deployed to address issues such as electromagnetic interference, switch voltage stress and harmonic distortion. The switching frequency of the inverter is ...
Wireless and Social Networks : Some Challenges and Insights
(2018-02-07)
Wireless networks have potential applications in wireless Internet connectivity, battlefields, disaster relief, and cyber-physical systems. While the nodes in these networks communicate with each other over the air, the ...
Studies on Single DC Link Fed Multilevel Inverter Topologies by Cascading Flying Capacitor and Floating Capacitor Fed H-Bridges
(2018-02-27)
Use of multilevel inverters are inevitable in medium and high voltage drives. This is due to the fact that the multilevel inverters can produce voltages in smaller steps which will reduce the harmonic content and result ...
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 ...
