Heuristics for Dual Coverage in Wireless Sensor Networks
(North Dakota State University, 2013)
Nowadays there is an increasing interest in wireless sensor networks due to their usage in a diverse range of applications such as telemetry and smart grids. In such networks, a valid concern is the minimization of the ...
FPGA-Based Simulation and Implementation of Induction Motor Torque Control Systems Based on Direct Torque Control (DTC)
(North Dakota State University, 2014)
Electric drives for induction machines are of great importance because of the popularity of this machine type. To design, simulate and implement such drives, fast, reliable digital signal processors are needed. Recently ...
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 ...
Analysis and Characterization of Cloud Based Data Center Architectures for Performance, Robustness, Energy Efficiency, and Thermal Uniformity
(North Dakota State University, 2014)
Cloud computing is anticipated to revolutionize the Information and Communication Technology (ICT) sector and has been a mainstream of research over the last decade. Today, the contemporary society relies more than ever ...
Formal Modeling and Verification Methodologies for Quasi-Delay Insensitive Asynchronous Circuits
(North Dakota State University, 2019)
Pre-Charge Half Buffers (PCHB) and NULL convention Logic (NCL) are two major commercially successful Quasi-Delay Insensitive (QDI) asynchronous paradigms, which are known for their low-power performance and inherent ...
Performance Enhancement of Pipeline ADCs
(North Dakota State University, 2014)
The pipeline ADC is mainstream architecture in wireless communication and digital consumer products because of its speed, resolution, dynamic performance, and power consumption. However, there are three areas of concern ...
Cardiac Output Improvement in Mechanical Circulatory Support Devices
(North Dakota State University, 2017)
Mechanical circulatory support devices (MCSDs) have gained widespread clinical acceptance as an effective heart failure (HF) therapy. The concept of harnessing the kinetic energy (KE) available in the forward aortic flow ...
Nonlinear Compensation in Optical Communications Systems using the Nonlinear Fourier Transform
(North Dakota State University, 2017)
Nonlinear effects in optical fibers impose a capacity limit for optical communication systems. In this dissertation, the nonlinear Fourier transform (NFT) is investigated as a method to mitigate and compensate for those ...
State-Space Randles Cell Model for Instrument Calibration
(North Dakota State University, 2020)
It is desirable to calibrate electrochemical impedance spectroscopy (EIS) instrumentation using a Randles circuit. This presents a challenge as realistic loads, simulated by this circuit, contain theoretical components ...
