Capacity and Life Estimation of Flooded Lead Acid Batteries using Eddy Current Sensors
(2018-01-04)
Lead acid batteries are widely used in domestic, industrial and automotive applications. Even after lot of advancements in battery technologies, lead acid cells are still in use because of their high capacity and low cost. ...
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 ...
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 ...
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 ...
Atomistic Study of Carrier Transmission in Hetero-phase MoS2 Structures
(2018-05-25)
In recent years, the use of first-principles based atomistic modeling technique has become extremely popular to gain better insights on the various locally modulated electronic properties of nano materials and structures. ...
