Machine Learning Applications: Cell Tracking And Nonparametric Estimation Of Non-Smooth Divergences, Mina Mahbub Hossain

All Graduate Theses and Dissertations, Fall 2023 to Present

This thesis brings together two important research directions: how to compare different sets of data more accurately, and how to better understand how brain cancer cells move and change shape.

In the first part, we look at a problem in statistics: measuring how different two data sources are from each other. Traditional methods often make strong assumptions, which may not always hold in real situations. Our approach avoids those assumptions by using an ensemble method, a way of combining many weak estimators into one stronger result. This makes the method more flexible and reliable, especially when dealing with complex or …

Why The Triple Bottom Line Fails: Advancing The Jesuit Vision For Sustainability Education In Business, Trevor Zink, Melissa Fitzpatrick, Justin Nordin, Jeffrey S. Thies

Journal of Management for Global Sustainability

This paper critiques the Triple Bottom Line (TBL) framework as conceptually flawed and ethically insufficient for sustainability education in business. While the TBL aims to balance profit, people, and planet, its logic prioritizes profitability, rendering social and environmental goals conditional and marginal. We argue that this framing undermines critical thinking, moral imagination, and ecological literacy in business students—especially within Jesuit institutions, which are called to form conscientious leaders. Drawing on Jesuit educational tradition, we propose a reorientation of business purpose around economic sufficiency rather than profit maximization, guided by integral ecology and the common good. This shift invites a more …

A Comparative Study Of Novel Methods For Variances, Taoreed Muritala

Boise State University Theses and Dissertations

Understanding variability is fundamental to knowledge advancement across various disciplines, including manufacturing, clinical research, biology and genetics. Population variances play a crucial role in processes such as quality control, treatment evaluation and the interpretation of biological mechanisms. However, statistical procedures for comparing variances across multiple populations remain less developed than those for comparing means. Classical omnibus tests, such as Bartlett's and Levene's, can detect overall variance heterogeneity but fail to identify which populations differ, thereby limiting their usefulness in multi-population analyses and increasing the risk of inflated family-wise error rates through repeated testing.

This thesis develops and evaluates three multiple …

Evaluation Of High Concentration Dissolved Oxygen Delivery On Wastewater Treatment Plant Performance, Gregor Ethan R. Posadas

Boise State University Theses and Dissertations

Microorganisms are used in wastewater treatment plants (WWTPs) to transform constituents and depend on dissolved oxygen (DO) for growth. Limitations in traditional treatment methods pose inefficiencies in performance relative to constituent removal. This study involved monitoring the performance of a selected WWTP located in Greenleaf, Idaho that was retrofitted with a high concentration DO delivery system. The WWTP was selected due to its small scale (classified as a minor discharge facility with a design flow <1 MGD) and capability of being retrofitted with a high concentration DO delivery system proprietary to BioSolution Holdings Co., Ltd. This study aimed to monitor the effects of delivering higher DO concentrations in the WWTP in conjunction with validating the performance and function of the retrofitted high concentration DO delivery system. The performance of the selected WWTP was monitored over the course of one year to capture seasonal fluctuations.

Stimulation And Recording Interfaces For Data Transmission To And From A Micro Neural Stimulation Device, Morgan Riley

Boise State University Theses and Dissertations

Advancements in neuromodulation for treating neurological disorders increasingly rely on selective peripheral nerve stimulation rather than whole-nerve activation. Traditional approaches engage all fascicles, causing off-target effects such as involuntary muscle contractions and pain. To address these challenges, this research proposes a minimally invasive microdevice that integrates wireless galvanic impulse communication with an epineural multi-contact nerve cuff. This design facilitates high-throughput, low-power stimulation, recording, and data transfer. Development efforts include optimizing neural stimulation protocols, validating deep tissue galvanic transmission, and fabricating a multi-channel nerve cuff for stable electrode–tissue interfacing. In parallel, custom depth-controlled intramuscular arrays enable high-density electromyography (EMG) recording during …

The Contribution Of Audition And Proprioception In Unisensory And Multisensory Target Reaching, Ivan Camponogara

All Works

Everyday actions often involve reaching for targets sensed by auditory and proprioceptive senses (reaching a ringing smartphone in the dark or tapping on it while holding it with the other hand). However, it is still unclear whether reaching performance toward auditory and proprioceptive targets is modality-specific and whether performance improves under multisensory compared to unisensory conditions. Here, we addressed these questions by measuring reaching performance toward auditory, proprioceptive, and combined audio-proprioceptive targets along the azimuth and depth dimensions. Accuracy was similar along the azimuth dimension, whereas precision was generally lower for auditory targets compared to proprioceptive and audio-proprioceptive targets. A …
