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 ...
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 ...
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 ...
A New Printed Quasi-Landstorfor Antenna
(North Dakota State University, 2011)
In this thesis, a new type of printed quasi-Landstorfer antenna is present ed. The
proposed antenna utilizes parasitic radiators to realize a higher gain. The antc1ma is
measured to have a resonant frequency of 2.45 GHz ...
A Sensor System Designed for Electrochemical Impedance Spectroscope-based Coating Performance Evaluation
(North Dakota State University, 2010)
One of the traditional methods for coating performance evaluation is using
Electrochemical Impedance Spectroscopy (EIS). The theory of using EIS to evaluate
coating performance is to measure the coating impedance in a ...
Image Sensor Classification System for Prosthesis Control
(North Dakota State University, 2010)
This paper proposes the integration of an image sensor classification system into the
control scheme for prosthetic limbs. The goal is to minimize the mental strain experienced
by brain-computer interface (BCI) users ...
Phasor Measurement Unit Placements for Complete Observability using Linear-Time, Quadratic-Time, and Subquadratic-Time Heuristics
(North Dakota State University, 2010)
A phasor measurement unit (PMU) is considered to have the potential to
improve the efficiency of electric power systems by monitoring, control, and protection.
Through measurements of all bus voltages, incoming and ...
Verification of Synchronous Elastic Pipelined Systems
(North Dakota State University, 2010)
The constant shrinking of technology has lead to several design challenges that
the synchronous design paradigm is unable to cope with. Elastic design is a novel and
promising design paradigm that overcomes many of these ...
