Evaluating the Usability of Respiratory Muscle Training Software: Insights for Guiding New Users
Get PDFRespiratory muscle training (RMT) has gained increasing attention for its potential benefits in both athletic performance and clinical applications. RMT involves targeted exercises to strengthen the respiratory muscles, such as the diaphragm, improving measures such as maximal inspiratory pressure and peak flow. The PowerBreathe K5 device is a widely used RMT tool; however, the usability of its accompanying software, BreatheLink, remains largely unexplored. This study evaluated the user experience of BreatheLink among first-time users through a structured usability assessment. Participants completed key tasks, including account creation, test and training sessions, and data visualization. Usability feedback was collected through task performance measures, post-task interviews, and post-study surveys. Findings indicate that while BreatheLink provides valuable training and testing insights, users faced challenges related to interface intuitiveness, navigation efficiency, and data interpretation. The study highlights critical usability concerns, suggesting improvements to enhance user experience and optimize training outcomes. Addressing these issues could improve software and device usability, ultimately broadening accessibility for the general populatio
Writing with AI Empowering Multilingual Voices in English
Get PDFThis is a two-part assignment I designed for multilingual students in a 100-level introductory composition course. The primary goal is to raise students’ awareness of English language varieties, have them explore how and why multilingual writers may approach writing differently from monolingual English speakers, and guide them to critically examine potential biases in AI toward multilingual writers. The assignment also encourages students to be thoughtful and discerning in their use of AI tools during the writing process. The first part takes place in class where students select a paragraph from a previously submitted essay and prompt Microsoft Copilot to revise it in various English varieties, including Standard American English and the English variety they personally speak. They then analyze and document the similarities and differences among the versions. Students ask Copilot to explain its choices, referencing grammatical features of the respective English varieties, and evaluate the accuracy of its explanations—particularly in relation to multilingual writers like themselves. These observations are shared and discussed with peers and as a class. The second part of the assignment is a written reflection in which students analyze their experience with the in-class activity. They have the option to collaborate with AI during the revision stage but are required to explain how this experience contributes to their development as academic writers. Ultimately, the assignment aims to inspire students to embrace their linguistic identities while cultivating critical engagement with AI-generated content

Solar Sailing Adaptive Control Around the Earth-Moon Lagrange Point L4 for Stellar Observations
Get PDFTo expand our knowledge about the influence of the Sun in the cislunar region, as well as our understanding of shocks due to Coronal Mass Ejections and large coronal magnetic reconnection, a solar sailing approach is proposed to separately capture lunar occultations and observe the solar corona from L4 of the Earth-Moon system. Single and multiple shooting techniques are described along with a pseudo arc-length continuation method for preliminary orbit design. Periodic orbits in the vicinity of L4 are obtained in the context of the Earth-Moon circular restricted three-body problem (CR3BP) and the Sun-Earth-Moon bi-circular restricted four-body problem (BCR4BP). Solar sailing is shown to offer a solution to a time-constrained problem by leveraging the neutrally stable dynamics of equilateral Lagrange points and solar radiation pressure. To assess mission feasibility, the spacecraft\u27s trajectory is initially designed using low-thrust propulsion in a nonlinear optimal control problem.
We further transition solar sailing periodic orbits to a higher-fidelity ephemeris model to account for actual celestial distances and planes of motion, as opposed to the CR3BP and BCR4BP. In short, we achieve propellantless non-planar quasi-periodic motion around L4 while the spacecraft transits the umbra of the Moon once per lunar synodic month using solar radiation pressure for orbit control. Rather than a single trajectory, we find a family of solutions using solar sailing to observe the solar corona and capture lunar occultations across different sail loading parameters. This research proves the feasibility of a mission concept to observe the solar corona and capture lunar occultations of distant stars. The results of this dissertation highlight convergence to solar sailing quasi-periodic orbits with sail characteristic accelerations of up to 0.175 mm/s2. In parallel, an adaptive control architecture, using integral concurrent learning, is proposed to account for fluctuations in the solar flux and degradation of the sail surface for long-term tracking to the nominal trajectory, enabling repeated observations of the solar corona within the Moon\u27s umbra cone. To achieve this, reflectivity control devices are proposed in the geometric mechanics formalism of the Special Euclidean group SE(3) and its tangent bundle TSE(3)
Automated Plant Morphological Assessment and Microbial Community Monitoring in Simulated Lunar Regolith
Get PDFUpcoming lunar bases will need to leverage in-situ resources to ensure long-term sustainability and reduce mission costs. One key challenge is food production, which could be addressed by growing crops in lunar regolith-based substrates. However, lunar regolith lacks essential nutrients, requiring organic amendments to support continuous plant cultivation. This study examined the impact of manure-amended lunar regolith simulant on Mizuna mustard growth while assessing microbial community diversity and functionality. To support this effort, a custom software pipeline utilizing an open-source library, PlantCV, was developed to automatically track plant leaf area and height via image analysis. Results indicated that amended rhizosphere microbial communities adapted with robust metabolisms related to organic matter decomposition and nitrogen cycling in a single growth cycle. Additionally, the automated pipeline reduced analysis time by 99.8% from manual measurements with high reproducibility for Mizuna. These contributions provide insight and resources for future large-scale lunar agriculture research
