A Precision Slip Frequency Detector
(North Dakota State University, 1957)The problem of measuring low values of slip of induction machines is present in most Electrical Engineering laboratories. A rather high accuracy of the determination is necessary for theoretical calculations of motor ... -
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 ... -
Dc'sign of Piezoelectric Energy Harvesting and Supercnpacitor Charging Circuits Using Optimized Duty-Cycle of Buck Converter
(North Dakota State University, 2009)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 ... -
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 ... -
Damping Interarea Oscillations in Power Systems with DFIG
(North Dakota State University, 2011)With rapid depletion of fossil fuels and increasing environmental concerns, the trend to capture renewable energy, especially through wind energy resources, is increasing. The doubly fed induction generator (DFIG) is the ... -
Solution Processing Electronics Using Si6 H12 Inks: Poly-Si TFTs and Co-Si MOS Capacitors
(North Dakota State University, 2011)The development of new materials and processes for electronic devices has been driven by the integrated circuit (IC) industry since the dawn of the computer era. After several decades of '"Moore's Law"-type innovation, ... -
Calculating Cardiovascular Lumped-Parameter Model Values by Injecting Small Volume Perturbations in an Isovolumic Heart
(North Dakota State University, 2011)Diagnosing cardiac patient problems contains many uncertainties, and to fully diagnose the patient's condition usually requires a lengthy drug regimen to see what works and what does not. Compounding this problem is that ... -
Minimum Entropy Generation in the Cardiovascular System
(North Dakota State University, 2011)This study was performed under the motivation to find a scheme that could describe the complex behavior of cardiovascular homeostasis. This is hypothesized to be manifested in a thermodynamic description of the cardiovascular ... -
