A Variable High Gain and High Dynamics Range CMOS Phase Shifter for Phased Array Antenna Applications
(North Dakota State University, 2016)
Phase shifters can adjust phases electronically and hence is very popular for phased array antenna applications where radiation angle can be scanned electronically avoiding bulky mechanical rotation arrangement. In this ...
Cloud Based Recommendation Services for Healthcare
(North Dakota State University, 2016)
With the inception of portable computing devices, enormous growth in the healthcare data over the Internet has been observed. Consequently, the Web based systems come across several challenges, such as storage, availability, ...
Dynamic State Estimation Assisted Power System Monitoring and Protection
(North Dakota State University, 2016)
The advent of phasor measurement units (PMUs) has unlocked several novel methods to monitor, control, and protect bulk electric power systems. This thesis introduces the concept of “Dynamic State Estimation” (DSE), aided ...
The Capacity Region of the Gaussian Z-Interference Channel with Gaussian Input and Weak Interference
(North Dakota State University, 2016)
We consider a wireless communication scenario with two transmit-receive pairs
where each of the transmitters has a message for its corresponding receiver and only
one of the receivers face interference from the undesired ...
An Active Power Supply Filter with Ultra Wide Bandwidth
(North Dakota State University, 2016)
An active transformerless common mode filter is designed for use with switching mode power supplies with a switching frequency greater than 1MHz. The filter utilizes an amplifier in a voltage sensing current adjusting ...
The Effects of 2.45 GHZ Radio Frequency Energy on Neurological Tissue Genes Using an Unrestrained Murine Model In Vivo
(North Dakota State University, 2016)
The effects that radio frequency (RF) energy has on the body is currently an inconclusive
and controversial topic. This is in part due to the differences and issues that can be found in
previous studies. This thesis ...
