Salt and Light Water Purification System

Ewing, Emile (2012-04-09)

The need for a proposed solution to help mitigate the world’s water crisis is presented. This need is not a new development in the 21st century, nor is the process of using electricity and chemicals to sanitize water. ...

Simulation and Characterization of an Exact Solvable Chaotic Oscillator and Matched Filter

Bailey, John Phillip, III (2012-07-23)

The simulation and characterization of a low frequency exact solvable chaotic oscillator and a corresponding matched filter is presented with discussion. The work builds on an existing design for the oscillator by realizing ...

Sound Attenuation Using MEMS Fabricated Acoustic Metamaterials

Yunker, William (2012-04-11)

Unlike traditional rotational gyroscopes, MEMS gyroscopes use a vibrating proof mass rather than a rotational mass to sense changes in angular rate. They are also smaller and less expensive than traditional gyroscopes. ...

A Technique for the Measurement of Relative Velocity between Parallel Plate Electrodes in Micromachined Structures

Dean, Robert (2006-05-15)

Numerous applications exist for microstructures that contain two parallel oriented electrodes that experience relative motion. It is often desirable to measure the relative velocity between the two electrodes and then ...

True Random Number Generation from a High Frequency Chaotic Jerk Circuit

Harrison, Remington (2019-12-05)

Shown in this work is a method for true random number generation by directly sampling a high frequency chaotic jerk circuit. A method for determination of the maximum Lyapunov exponent, and thus the maximum bit rate for ...

Two Novel Relaxation Oscillator Interface Circuits for Resistive and Capacitive Sensors

Hatfield, Emily (2023-11-27) ETD File Embargoed

Presented in this thesis is the design and testing of two novel interface circuits for capacitive and resistive sensors. In both cases, the interface circuit is a modified CMOS inverter based relaxation oscillator, which ...

Typical Response of the ADXRS300 Microelectromechanical Systems (MEMS) Gyroscope in Acoustically Harsh Environments

Castro, Simon (2009-08-03)

In this thesis, the basic theory behind vibratory MEMS gyroscopes will be discussed to show how some of the design parameters originate. Also, a survey of commercially available MEMS gyros will be presented. In addition, ...

Wireless Communication of a Chaotic Waveform

Abell, William (2015-05-18)

Over the past couple of decades, mathematical equations have been developed that successfully model natural phenomena that occur in various fields such as chemistry, biology, and fluid mechanics. These equations, however ...
