Design, performance, and analysis of a multi-level air permeability test
The design, performance, and analysis of a soil vapor extraction system to identify zones most conductive to air transport and quantify kair in sequential soil layers is presented. A multi-level extraction well, with alternating solid and screened sections, was utilized to characterize …

Performance and Analysis of a Deployable Diffractive Optical Element for Small Satellite Missions
As space missions push toward smaller, lighter, and more deployable instrumentation, diffractive optical elements (DOEs) offer a compelling alternative to traditional optics. Their ability to focus light through engineered phase profiles rather than curved surfaces allows for large-aperture, flat …

The Limits of Indeterminacy: The Performance and Analysis of Selected Indeterminate Compositions by John Cage and Earle Brown
… elucidates the relationship between notation, performance practice, and musical realization in several indeterminate compositions by John Cage and Earle Brown. While both Cage and Brown emphasized the multiplicity of possible outcomes in these works, the distinct configurations of fixed and …

An extensible Web tool for the collection, sharing, and annotation of audio documents
… of rich, time-based media such as audio and video documents. However, the ability to categorize and index these documents has not improved comparably, a limitation for humans and machines alike to browsing, retrieving, and making sense of them. Motivated by a need to collect and annote …

Analysis of three different dielectric substrates on square ring microstrip antenna for wireless application
The sizes and weights of various wireless electronic systems (e.g. mobile handsets) have rapidly reduced due to development of modern integrated circuit technology. However, microstrip antenna suffers from low bandwidth. The objective of this project was to improve the bandwidth by proposing square …

Work Function Analysis of Vegetarian Entree Production
… areas observed were the ingredient assembly area and the cooks' production area. This labor time was recorded by Work Functions to find the dis- tribution of labor time. Data from the observations were compiled using an Apple II computer system. Reports were generated to show: a) observed …

Low-power high-performance SAR ADC with redundancy and digital background calibration
As technology scales, the improved speed and energy eciency make the successive- approximation-register (SAR) architecture an attractive alternative for applications that require high-speed and high-accuracy analog-to-digital converters (ADCs). In SAR ADCs, the key linearity and speed limiting …

The Performer as Analyst in the Piano Sonata Opus 12 by Jean Sibelius
<p>This thesis examines and models the process of analysis as a means for performers, particularly pianists, to engage with the large-scale organizational features of musical works, using the Piano Sonata, Opus 12 by Jean Sibelius as a case study. The unique character and structure of each of the …

The neural correlates of Human Spatial Memory and Representation
… This behaviour relies on spatial representation and memory within the brain. With these representations, we are able to construct what has been described as a “cognitive map” (Tolman, 1948) that allows us to accurately direct ourselves within our environment, be it throughout a city or within a …
