Active Noise Cancellation

ABSTRACT

In this project, I tried to build a noise-cancellation system using DSK. Two microphones and one speaker were used in the system: the first microphone is to sample unexpected noises from the outside and the second microphone is to collect all the sounds, Continue reading

Detection of Breathing and Infant Sleep Apnea

ABSTRACT

Sleep apnea is a condition where people pause while breathing in their sleep; this can be of great concern for infants and premature babies. Current monitoring systems either require physical attachment to a user or may be unreliable. This project is Continue reading

Lip Detection and Adaptive Tracking

ABSTRACT

Performance of automatic speech recognition (ASR) systems utilizing only acoustic information degrades significantly in noisy environments such as a car cabins. Incorporating audio and visual information together can improve performance Continue reading

Trajectory Optimization for a Mars Ascent Vehicle

ABSTRACT

The trajectory design, propellant loading, and staging of a Mars Ascent Vehicle (MAV) can be accomplished via the solution of the associated optimal control problem under given vehicle, mission, path and control constraints. This paper presents the Continue reading

Enhanced Learning–Combining MATLAB Simulation with Telecommunication Instructional Modeling (TIMS™) in a Senior Level Communication Systems Course

ABSTRACT

In this paper we present the successes of combining MATLAB™ simulation methods with the Telecommunication Instructional Modeling System (EMONA-IMS™) to provide experiential learning in our senior level wireless communication systems course. Continue reading

Visible and Mid-Infrared Supercontinuum Generation and their Respective Application to 3D Imaging and Stand-off Reflection Spectroscopy

ABSTRACT

The thesis describes broadband supercontinuum (SC) generation in optical fibers for both the visible and mid-infrared regions of the spectrum, and their respective application to 3D imaging and stand-off reflection spectroscopy. Both SC sources leverage mature Continue reading

Ultra-Short Baseline Acoustic Positioning System

ABSTRACT

This paper explains the design, implementation, and testing of an ultra short baseline (USBL) acoustic positioning system for the Amador Valley High School (AVHS) Robotics Clubs Barracuda Mark-X AUV. The system will be used to locate an Continue reading

Early Forest Fire Detection via Principal Component Analysis of Spectral and Temporal Smoke Signature

ABSTRACT

The goal of this study is to develop a smoke detecting algorithm using digital image processing techniques on multi-spectral (visible & infrared) video. By utilizing principal component analysis (PCA) followed by spatial filtering of principal component images Continue reading

Design, Characterization and Application of a Multiple Input Stethoscope Apparatus

ABSTRACT

For this project, the design, implementation, characterization, calibration and possible applications of a multiple transducer stethoscope apparatus were investigated. The multi-transducer sensor array design consists of five standard stethoscope Continue reading
