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 ...
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 ...
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 ...
Hybrid Renewable Energy System with Wind Turbine and PV Panels
(North Dakota State University, 2010)
In recent years, there has been increasing concern about the world's heavy
dependence on fossil-based fuels and the pollution caused by such fuels. This has sparked
an increased interest in the use of other renewable ...
Joint Compression and Encryption
(North Dakota State University, 2010)
This research work proposes two techniques of joint compression and encryption using
Shanon Fano Elias coding and Arithmetic coding respectively. The first scheme proposed
is called Adaptive Shannon-Fano-Elias code where ...
Refinementbased Verification of Elastic Pipelined System with Early Evaluation
(North Dakota State University, 2010)
This thesis presents a formal verification procedure to check correctness of the synchronous
elastic pipelined system that incorporates early evaluation against its synchronous
parent system. Note that the goal of the ...
Dc'sign of Piezoelectric Energy Harvesting and Supercnpacitor Charging Circuits Using Optimized Duty-Cycle of Buck Converter
(North Dakota State University, 2010)
Energy harvesting has been proved to be an innovative solution to replace the
batteries in remote power supply applications. Unfortunately, the limited capacity
aucl low efficiency of power conversion restrict the practical ...
