An Exploration In Atmopsheric Gas Burners, Brandon Flanigan

Masters Theses and Doctoral Dissertations

The objective of this paper is to explore the significant factors for primary aeration in atmospheric gas burners. Historically linear relationships have been used to estimate primary aeration with a design’s geometry and features. With a given heating output a burners geometry is designed to meet safety, efficiency, reliability and customers’ expectations. This paper explores the significant factors and how they interact with primary aeration. Experimentally exploring, port area, port loading, injector axial position, injection angle and the throat diameter interaction with port area. The structure creates an outline for atmospheric burner design.

Biomarker Discovery In Inflammatory Bowel Diseases Using Network-Based Feature Selection, Mostafa Abbas, John Matta, Thanh Le, Halima Bensmail, Tayo Obafemi-Ajayi, Vasant Honavar, Yasser El-Manzalawy

Electrical and Computer Engineering Faculty Research & Creative Works

Reliable identification of Inflammatory biomarkers from metagenomics data is a promising direction for developing non-invasive, cost-effective, and rapid clinical tests for early diagnosis of IBD. We present an integrative approach to Network-Based Biomarker Discovery (NBBD) which integrates network analyses methods for prioritizing potential biomarkers and machine learning techniques for assessing the discriminative power of the prioritized biomarkers. Using a large dataset of new-onset pediatric IBD metagenomics biopsy samples, we compare the performance of Random Forest (RF) classifiers trained on features selected using a representative set of traditional feature selection methods against NBBD framework, configured using five different tools for inferring …

Computational Methods For Segmentation Of Multi-Modal Multi-Dimensional Cardiac Images, Shusil Dangi

Theses

Segmentation of the heart structures helps compute the cardiac contractile function quantified via the systolic and diastolic volumes, ejection fraction, and myocardial mass, representing a reliable diagnostic value. Similarly, quantification of the myocardial mechanics throughout the cardiac cycle, analysis of the activation patterns in the heart via electrocardiography (ECG) signals, serve as good cardiac diagnosis indicators. Furthermore, high quality anatomical models of the heart can be used in planning and guidance of minimally invasive interventions under the assistance of image guidance.

The most crucial step for the above mentioned applications is to segment the ventricles and myocardium from the acquired …

Encouraging Children To Actively Recycle: A Mobile Application To Promote Recycling In The Dominican Republic, Noelia A. Rivera Pagan

Theses

The Dominican Republic generates 14,000 tons of solid waste daily, 49% of this is recyclable, but only 5% is. This waste is causing health problems, affecting the tourism industry, and the quality of life of its residents. Problems of confusion, lack of motivation, and lack of prioritization of the activity, affect the decision-making process when recycling.

What if there was a way to motivate the Dominican population to recycle, and change the behavior towards this activity? Children learn new behaviors faster than adults. Why not use this opportunity to incorporate the engaging factor of design and technology to help improve …

Behind The Lens, Guoxiang Zhao

Theses

Time flies. I arrived at my thesis year after two years of study at RIT, and began working on my film “Behind the Lens.” The film runs for five minutes and 56 seconds, and includes hand-drawn animation, music and sound created by me. After some personal changes, I re-pitched a whole new thesis proposal in the fall semester of my thesis year because I felt passionate and committed to the important message of the film. In truth, this story didn’t have a clear outline until April in my last semester. The story is about a camera character going through his …

A Hidden Technological Assumption In Patent Law: The Case Of Gene Patents And The Disclosure Requirement, Or Cohen Sasson

Articles

The disclosure requirement in patent law is designed to reveal knowledge regarding a patented invention to allow proper understanding and utilization of that invention. The contention offered here is the presence of an inherent incompatibility between the disclosure requirement and genetic inventions. Genetic inventions are highly contingent on genetic statistical data (GSD), which is gathered during the commercial phase of a genetic invention. GSD are essential for various purposes, which at least some should be satisfied by the disclosure. However, since GSD can be gathered only at the postapplication period, GSD are not disclosed through the disclosure requirement. Therefore, there …

Noninvasive Ventilation Protocol Development, Janise Pierce Tinsman

Doctoral Dissertations and Projects

Endotracheal intubation results in many serious complications including regurgitation, vocal cord paralysis, and death. Noninvasive ventilation using bi-level positive airway pressure has been shown to provide the necessary support without intubation and is also associated with better outcomes if trialed prior to endotracheal intubation. A noninvasive ventilation protocol was applied in a rural acute care facility. Results: The average length of stay for acute respiratory failure decreased from 5.32 to 4.44 days, while intubations fell from 41.9% to zero, and mortality fell from 9.7% to zero during the pilot period. Five cases met criteria for noninvasive ventilation, and three received …

Declining Church Attendance: Five Reasons Why Millennials Have Stopped Attending Church, Charles Eugene Sumpter

Doctoral Dissertations and Projects

During the past decade, every denomination has recorded a decline in church attendance despite a continual increase in the US population. Research organizations including the Barna Group, Pew Research, and the Hartford Institute of Religion Research conducted an untold number of surveys providing statistics that ascertain reasons for declining church attendance and why people are leaving the church. Failure to address the issue of declining attendance will lead to more church failures and an increased number of people with no church affiliation. This research document will review data from the Barna Group, Pew Research, and the Hartford Institute of Religion …

The central question guiding this study is, “how do elementary school counselors describe their training applicability to foster and promote students’ social-emotional wellbeing?” …

Missional Metamorphosis: How Identity, Presence, And Praxis Are Reshaping Disciple Making Within Post-Christian Contexts, Justin Thomas Wester

Doctoral Dissertations and Projects

The American Church’s current disciple-making paradigm is struggling to engage post-Christian contexts with the gospel of Jesus Christ. Despite American society’s steady trending away from a biblical worldview, dwindling church attendance, and declining religious affiliation, the American Church is still operating under a disciple-making paradigm conducive for the Christendom era. What changes must occur to help churches break away from an antiquated paradigm and embrace a more contextually appropriate expression? This project helps to answer that question by capturing and expressing how changes in ecclesial identity, contextual presence, and corporate praxis are altering disciple-making paradigms within post-Christian contexts. Utilizing quantitative …
