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 ...
Metamaterial-Inspired Reconfigurable Series-Fed Arrays
(North Dakota State University, 2014)
One of the biggest challenges in modern day wireless communication systems is to attain agility and provide more degrees of freedom in parameters such as frequency, radiation pattern and polarization. Existing phased array ...
Islanding Detection Using Data Mining Techniques
(North Dakota State University, 2015)
Connection of the distributed generators (DGs), poses new challenges for operation and management of the distribution system. An important issue is that of islanding, where a part of the system gets disconnected from the ...
Novel K2W7O22/Ti3C2 Nanocomposite-Based Sensor Device for Breath Acetone Analysis in Diabetic Patients
(North Dakota State University, 2020)
Acetone in exhaled breath is gaining attention as a non-invasive means of quantifying blood glucose levels in Diabetics. This calls for development of novel biosensors for the detection of trace concentrations of acetone ...
Impedance-Based Wireless Sensor Network for Metal-Protective Coating Evaluation
(North Dakota State University, 2011)
Research has focused on the influences of flowing fluid on the corrosion of bare metals, but there is little emphasis on the degradation of metal-protective coating. Evaluating the metal-protective coating usually uses the ...
Impedances of a Cubical Quad Antenna
(North Dakota State University, 1965)
Rectangular loop antennas and short electric dipoles
are two of the oldest antennas in existence. In 1888,
twenty years after Maxwell invented his famous Maxwell's equations,
Hertz used these two antennas to prove ...
Characterization of Inflationary and Deflationary Auscultatory Blood Pressure Measurements
(North Dakota State University, 2022)
This document is a paper-based dissertation. The dissertation is a collection of articles
written by the author in the pursuit to develop a novel method to measure blood pressure (BP).
The introduction chapter describes ...
Impact of Inverter-Based Resources on Grid Dynamics
(North Dakota State University, 2022)
The increasing integration of renewable energy resources such as wind and solar into the electric power grid through power electronic inverters has changed grid dynamics and posed challenges to grid planning, ...
