Development And Validation Of A Probe Tube Placement Training Simulator, Robert Koch

Electronic Thesis and Dissertation Repository

For over 90% of individuals with hearing loss, hearing aids are the primary method of treatment. Recent studies have shown that most hearing aids are not personalized properly to patients, resulting in poor hearing outcomes. Poor training methods has been proposed as a possible reason for these findings.

A training simulator was developed consisting of a mannequin head with flexible, anatomically correct ears, and an optical tracking system for tracking the insertion of diagnostic equipment into a 3D printed ear canal. The simulator provides an outlet for trainees to practice their clinical procedures while receiving validated feedback, without the need …

Improvement Of Fluorescence-Based Microfluidic Dna Analyzers, Collin Tranter

Doctoral Dissertations

A tremendous effort continues in the development of micro-total-analysis-systems; in support of this, many chemical passivation methods have been developed to enhance the biocompatibility of such microfluidic systems. However, the suitability of these passivation techniques to many fluorescence-based assays still remains inconsistent. This part of this work is focused on the performance of a third generation intercalating DNA dye when used within microfluidic devices treated with a select variety of passivating coatings. The results of these tests indicate that passivation coatings which are intended to shed DNA based on electrostatic repulsion will in fact imbibe the fluorescent DNA intercalating dye …
