Designing and building a home Media Center can be a daunting task given the multitude of available options and configurations. The goal of this project is to build a home Media Center, and in the process, create a guide that a less technically knowledgeable person could use to build their...
Wireless technologies advance rapidly in the recent time. The maJor initiative is the realization of the third generation wireless network that provides high bandwidth access to digital data on the Internet. Moreover, recent improvements in computer and embedded systems have enabled portable devices with sufficiently high computing capability.
The combination...
We construct a website to explain how Gaussian mixture models can be optimized using the expectation maximization algorithm. Previous free, online material on this process has been extremely limited. All sources surveyed failed to entirely describe our identified criteria for an in-depth description and useful visualizations. After surveying a variety...
Empowering pedagogy (also know as “transgressive,” “emancipatory,” or “democratic” forms of education) seeks to challenge the historically oppressive tendencies of traditional education. As a student of Social Justice and International Studies, I approach the topic of empowering pedagogy through a case study. My research explored this non-traditional educational philosophy and...
Terahertz (THz) frequencies of the electromagnetic spectrum have been underutilized when compared to neighboring microwave and infrared frequencies, largely due to the difficulties controlling and detecting these fields. In a step toward gaining control over THz frequencies, my advisor Dr. Yun-Shik Lee’s group experimentally demonstrated optical-pulse THz-control over a plasmonic...
Terahertz (THz) spectroscopy is a great tool not only to study fundamental physical processes such as many-body Coulomb interaction but also to develop ultrafast electronic devices. More specifically, intense THz fields interacting with semiconductors have exhibited strong nonlinear effect involving extreme carrier dynamics. In this experiment, intense THz radiation was...
High field time-domain terahertz spectroscopy (TDS) is used to determine the time dependent transmission and the time-delay and optical-power dependent conductivity of a wafer of gallium arsenide (GaAs). Gallium arsenide is a direct band-gap semiconductor and has potential as a computer processor component. Analysis of the transmission of terahertz (THz)...
Carbon nanotubes are the subject of intense interest in virtually every field, from medicine to
nano-scale electrical components. Multi-walled nanotubes exhibit a strong nonlinear response
to high-field strength terahertz radiation. This research uses terahertz pulses with field strength
exceeding 1 MV/cm generated by means of optical rectification utilizing a lithium...
In this work sample, a student teacher implemented ESOL standards and
strategies on a unit covering chemical compositions in a high school chemistry
classroom. The ELD program at this high school has two types of ELD classes. ELD 1/2
classes have a grammar-based curriculum focused on the English Language, while...
Semiconductors serve an integral role in our technologies today. However, with new advancements in ultra-fast electronics, we are approaching the fundamental speed limits of traditional silicon-based semiconductors. Silicon-based semiconductors typically exhibit photocarrier dynamics in nanosecond timescales. Transition metal dichalcogenides (TMDs) are 2D materials shown to exhibit photocarrier dynamics in picosecond...
