Development And Evaluation Of Wireless Monitoring Systems For Touchless Respiratory Monitor Validation, Dustin Marquardt

Graduate Theses & Non-Theses

The Touchless Respiratory Monitor (TRM) is a non-invasive system that uses contactless methods to measure respiratory rate and tidal volume. The main technologies employed are LiDAR for tidal volume measurement and a thermal camera for respiratory rate monitoring. These novel methods require validation against established techniques such as capnometry and respiratory inductance plethysmography. Commercial respiratory monitoring equipment is often expensive and dependent on proprietary software, creating barriers to widespread use. To address this, a custom, modular, and low-cost evaluation system was developed to streamline the validation of the TRM. The prototype system integrates a pulse oximeter, capnometer, spirometer, and respiratory …

Aqueous Geochemistry Drives Microbial Cu, Fe, And Zn Uptake Rates In Yellowstone, A Continental Hydrothermal System, Eva Carolina Andrade-Barahona

Graduate Theses & Non-Theses

Microbial uptake of trace metal cofactors such as copper (Cu), iron (Fe), and zinc (Zn) is governed by biogeochemical processes in hydrothermal systems where metal bioavailability varies widely. In situ microbial metal uptake rates were quantified by applying metal stable isotope probing (MSIP) in the Yellowstone hydrothermal system across diverse geochemical conditions in hydrothermal springs. The findings in these studies revealed that pH exerts a dominant influence on microbial copper uptake rate, also enhanced by increased Cu²⁺ ion availability and dissolved oxygen. Microbial iron uptake, in contrast, displayed a broad tolerance to environmental variability, occurring across a pH range of …

Functional Impact Of Single Nucleotide Polymorphism Rs4129009 (Ile775val) On Human Toll-Like Receptor 10, Audrey N. Koti

Biology Student Research

Toll-like receptors (TLRs) are a subclass of pattern recognition receptors within the

innate immune system that detect pathogen-associated and danger-associated molecular patterns,

thereby initiating host defense responses. The human TLR family comprises ten receptors (TLR1

– TLR10), each recognizing structurally conserved microbial motifs such as bacterial

lipoproteins and viral nucleic acids. The ligand specificities, adaptor protein recruitment, and

downstream signaling cascades have been well-characterized for TLR1 – TLR9, which

predominantly engage MyD88- or TRIF-dependent pathways to activate pro-inflammatory

transcription factors including NF-κB. In contrast, the ligand specificity and intracellular

signaling mechanisms of TLR10 have yet to be fully elucidated. Emerging …

Lifetime Prediction Of Electrolytic Capacitors Under Variable Loadings In Electric Vehicles For Prognostics And Health Management Applications, Jaewon Lee

Electronic Dissertations and Theses, 2010-current

Aluminum electrolytic capacitors (AECs) are widely used in electric vehicles (EVs) power electronics but are also a primary source of wear-out failures. Most previously proposed lifetime models were derived under constant loading conditions and therefore cannot capture variable loading arising from seasonal or diurnal temperature swings and user-dependent driving profiles in EVs. This study develops a variable-loading lifetime prediction framework for AECs, which can be further extended to prognostics and health management (PHM). Collectively, the results of the study demonstrate a framework suitable for PHM application, in which SoD-based lifetime prediction yields reliable predictions under variable loadings. An appropriate lifetime …

A Trigger For The Autonomous Decommissioning Of Smart Devices, Ravindra Mangar, Jared Chandler, Jingyu Qian, Carl A. Gunter, Timothy J. Pierson, David Kotz

Dartmouth Scholarship

Smart devices are ubiquitous in modern environments, yet their decommissioning phase remains poorly studied and often overlooked in system design. We define secure decommissioning as the process by which a smart device securely disconnects from its environment and makes sensitive data inaccessible. If not decommissioned, devices may retain sensitive information – such as security credentials or user-behavior data that could be recovered by an adversary. Unfortunately, some users may forget to decommission a device when they dispose or sell it, and cannot decommission a device that is lost or stolen. This paper investigates a trigger mechanism for individual wireless smart …

Mitochondrial Calcium Uniporter Regulates Itam-Dependent Platelet Activation, Jehiel Abigail Ajanel Gomez

Arts & Sciences Graduate Student Theses and Dissertations

Thromboembolic conditions are the leading cause of disability and death in the United States. Platelets play an important role in the pathophysiology of thrombus formation by aiding in the formation and stabilization of the clot. Central to platelet activation is cytoplasmic calcium, which increases after platelet activation through ITAM (Immunoreceptor tyrosine-based activation motif) or GPCR (G-protein-coupled receptor) receptors. Platelet mitochondria rely on cytoplasmic calcium for mitochondrial calcium influx, which is critical for ATP formation and regulation of mitochondrial reactive oxygen species. In other cells, mitochondrial calcium entry is regulated by the multimeric protein complex, mitochondrial calcium uniporter (MCU). Deletion of …

Strategies To Streamline Patient Appointments In Specialty Outpatient Care, Adama Drammeh

Walden Dissertations and Doctoral Studies

Abstract Outpatient addiction treatment centers face significant challenges from inefficient appointment scheduling systems that contribute to high no-show rates, delayed care, and weakened organizational performance. These barriers affect more than daily operations; they disrupt the flow of treatment, increase patient disengagement, and place additional strain on limited healthcare resources. For patients navigating substance use disorders, a missed appointment may jeopardize continuity of care and undermine recovery efforts.

Effects Of Integrated Biological And Chemical Fertilization On Pecco And Banji Shoot Development In Tea Plants, Intan Ratna Dewi Anjarsari, Muhammad Raihan Abdillah Farros, Santi Rosniawaty

Jurnal Kultivasi

Tea productivity and quality are largely determined by shoot structure, particularly the balance between pecco shoots (tender buds and young leaves) and banji shoots (older, less productive shoots). Conventional reliance on inorganic fertilizers often enhances overall growth but does not necessarily improve shoot structure, while biofertilizers alone provide limited nutrient availability. This study aimed to evaluate the effects of combining microbial-based liquid biofertilizers with inorganic fertilizers on the structure of tea shoots. The experiment was carried out on seed-derived tea plants using a randomized block design with several fertilization treatments, including sole biofertilizer, sole inorganic fertilizer, and their combinations. The …
