    Between the Earth and Sky

    No full text
    Abstract: Between the Earth and Sky How do you find balance? In these days, balance is necessary, more than ever. My project is a 3-part series of mixed media portraits, called Between the Earth and Sky, based on a poem I wrote of the same name. The subject is a personal one, about going back and forth between emotions, and trying to navigate the ebb and flow of everyday life as though it were a stormy sea. However, both this project and my poem was meant to represent the inner balance that I was able to find. Balance between experiencing all of the seasons of life, both the good and the bad, both the thorny vines and the red roses. I hope that the viewer will walk away remembering there is peace to be found within the tides of dark and light, and we can always find this peace within ourselves

    Feminine Rage

    No full text
    The inspiration for these paintings has been brewing inside my head for quite some time now. I wanted to make a project about how crushing it feels when you just can\u27t seem to understand. That time you got angry at yourself and even those around you for not understanding the statistics homework after three people tried to help you. Pent up anger, or sadness. That time you threw your phone at the wall because of a cyclical, frustrating argument. A \u27cherry-on-top\u27 outburst that comes from a place complete frustration. As well as a place of fear. Is that a fear of being taken advantage of? Is it a fear of being stupid? A fear of being weak? Being too emotional makes people feel vulnerable, or even weak. When you\u27re emotions are so large, it feels like they\u27re taking up too much space. Like they might get in the way of perfectly good things. Words and poetries, textures, images of the female body and human flesh and flowers are all representative of vulnerability and are used to do so in this project. Choosing to be vulnerable in comfortable environments can be freeing and necessary. That is, only when it is you who chooses to make you feel vulnerable

    Chronic diseases like cardiovascular diseases and diabetes account for a considerable proportion of worldwide mortality rates, and early detection and prevention are pivotal. The purpose of this project is to create a model that predicts the onset of chronic disease using available physiological data from wearable devices. The system aims to apply machine learning and deep learning methodologies to generate early warning alerts for the patient and their caretakers, as well as personalized preventive care based on continuous health monitoring of the patient. Wearable technologies, despite the current battery life and device bulkiness limitations, represent a promising avenue for collecting and analyzing health data at scale(Yanagita, M. (2023)). The project also includes a web platform that will promote a community where patients, doctors, and other healthcare professionals can share knowledge and provide and receive support. It would be a central site for tracking risk factors, providing health alerts, and enabling early treatment. In the longer run, this two-phase program is intended to transform chronic disease management by providing users with accurate prediction, to help to reduce dependence on expensive traditional tests and placing the power in the users\u27 hands to enable them take responsibility of their health(Yanagita, M. (2023)). Keywords: Chronic disease prediction, wearable health devices, early detection, preventive healthcare, machine learning, deep learning, real-time monitoring, health analytics, digital health platform, personalized medicine, health forecasting, cardiovascular disease, diabetes, health data integration, patient engagement.

    Wearable health monitoring systems, integrated with data-driven predictive models, are transforming personalized healthcare by enabling early disease detection and proactive intervention. Traditional health monitoring relies on rule-based thresholds and prior medical knowledge, limiting adaptability to individual variations. This project leverages machine learning models—Random Forest, Support Vector Machines (SVM), and Neural Networks—to analyze physiological data from wearable devices, enhancing predictive accuracy in detecting conditions like heart disease and sleep apnea. The study addresses the growing need for real-time, personalized health monitoring, particularly as populations age and chronic diseases become more prevalent. Arizona serves as a testbed for validating model performance under real-world conditions. Data is collected from pulse ellipsoid levels, sleep wave patterns, ECG readings, and blood oxygen saturation (SpO₂) measurements. A structured preprocessing pipeline ensures data quality, employing missing value imputation, normalization, and feature engineering to enhance model performance. Evaluation metrics, including accuracy, precision, F1-score, and cross-validation, validate the models. A key challenge—performance deterioration with new data—is mitigated through retraining strategies. Live health monitoring with alert mechanisms further enables real-time detection of abnormalities and early medical intervention. Findings demonstrate that machine learning-based predictive models outperform traditional methods in detecting health risks and enabling preventive care. This study concludes that integrating predictive analytics into wearable devices enhances personalized healthcare, improving patient outcomes and reducing emergency health events

    Using Computational Fluid Dynamics to Examine Fluctuating Pressure in Pitot Tube Measurements

    No full text
    This project utilizes Computational Fluid Dynamics (CFD) to analyze the accuracy and behavior of a pitot tube in measuring the speed of a moving bicycle. A pitot tube is a common device for measuring fluid velocity by comparing the stagnation pressure of a moving fluid to the static pressure. CFD can simulate the fluid flow using governing equations of conservation of mass, momentum, and energy. The CFD is done using SimScale, a free to use, cloud-based software. By simulating riding conditions, this project will examine the aerodynamic interactions between the pitot tube and the surrounding airflow. Values such as the stagnation pressure can be extracted while also investigating a more detailed view of the behavior of the air inside the pitot tube. Fluctuating pressure measurements have been observed in an experimental setting, so the goal of this project is to test 3 different diameters of the pitot tube for their steadiness in the measured pressure. The results of this study help determine the feasibility of using pitot tubes on bicycles and provide insight into the measurements that the pitot tube is making in the real world

    The MESS Project

    Get PDF
    Sensit Technologies, based in Valparaiso, IN, manufactures gas leak detection equipment. They currently utilize a locally-developed Manufacturing Execution System to gather production data for analytics, but they desire a replacement with additional features such as providing work instructions (currently paper-based) and gathering more detailed information. This project sought to create a more fully featured version of the existing locally built suite, known as MESS (Manufacturing Execution Software System). This new version of MESS is a web-based application with an SQL database and is developed using C#, Blazor, and ASP.NET Core Identity. New features include allowing operators to record their part of a product’s assembly step by step, documenting failures, and automatic step timing. As an additional customer need, MESS 2.0 has enhanced batch part number entry with a QR code scanner and access to work instructions in multiple formats. Incorporated into MESS 2.0 is “Phoebe,” an additional administration interface that manages users, configures product lines, and controls workstation access. The enhanced system should also provide customer service representatives with increased part traceability features to track components for recalls and support. MESS 2.0 will enable optimized assembly processes while maintaining Sensit Technologies’ commitment to quality workmanship and rapid turnaround by integrating real-time production balancing (rebalance) and structured work instruction management. Primary software engineering challenges faced in this project were understanding the customers\u27 in house vocabulary and finding solutions that meet existing software needs while simultaneously accommodating for new requirements

    Turning Angels in Devils: The Portrayal of Christianity in Anime

    No full text
    Although Christian characters and themes appear fairly frequently within western media, this occurs less so with Japanese media. The population of Christians in Japan has remained fairly consistent in the past century, occupying approximately one percent of the population. For centuries prior to the Meiji Restoration (1868), Christianity was made illegal by daimyō Hideyoshi. As a country with few Christian—as well as a history of Christian persecution—Japanese media tend to have a more surface level understanding of Christianity, if Christianity is even referenced at all. Popular Japanese media (particularly anime, the focus of this research) tends toward the aesthetic use of Christianity, but within those uses, as well as the more significant uses of Christian characters and themes, we can observe the underlying cultural attitudes toward Christians and Christianity. These cultural attitudes, outside of the aesthetic, tend toward negative portrayals and thus a general negative perception of Christianity, although the extent of negativity broadly correlates with the level of power an individual or entity has within the Christian hierarchy. For instance, laypeople exist on the spectrum of somewhat sympathetic yet naïve victim characters to abusers, while supernatural entities like angels exhibit broader levels of corruption and debauchery, if their corruption does not extend to wanting to destroy humanity. While it remains unclear if the negativity of these portrayals exists as purposeful decisions by the stories’ creators or unintentional happenstances, they reflect the persistence of negativity toward Christianity from the time of Jesuit missionaries and the anti-Christian edicts of daimyō Hideyoshi

    A Dynamic Leadership Approach in Different Situations and Contexts

    This paper is one of the first to provide empirical evidence supporting the conceptualization of a dynamic leadership approach in which employee maturity and organizational dynamism help leaders make the right choice of leadership styles to improve employee job satisfaction. As business environments change and employee maturity differs in this dynamic business era, and as there is a chaos characterized by numerous leadership styles in the leadership literature, adopting a dynamic leadership approach has become important to identify the most effective leadership styles suitable for employees. A quantitative study using conditional process analysis was conducted to examine a dynamic leadership approach that draws on servant/transactional/transformational leadership to influence employee job satisfaction in stable and turbulent environments. Results indicated that leaders could employ transactional/transformational/servant leadership styles to further improve employee job satisfaction and should adopt servant leadership when the organizational environment is stable or weakly dynamic and should adopt transformational leadership when the environment is moderately dynamic. Results also show that highly mature employees mediate the relationship between transformational/servant leadership and job satisfaction. Findings supported the development of a new dynamic leadership approach in which leaders can skillfully change their leadership style over time by navigating through multiple leadership styles as appropriate depending on the organizational dynamism and employee maturity levels

    The Nameless Enemy: How Do You Solve a Problem Like “Mairon”?

    Get PDF
    This paper analyzes Sauron’s “original” name, “Mairon,” in its various contexts (textual, temporal, and linguistic) and then applies it to a reading of the character in order to produce a “capsule characterization” or “minimyth” for the Lord of the Rings himself. The name “Mairon” appears only in a note to a single entry in a list of Eldarin roots, not published until 2007 in the journal Parma Eldalamberon. This niche location suggests one of the many ways in which this name is marginal: typographically, linguistically, narratively, and historically (as in the Secondary World). The name appears to have been conceived during a flurry of revision to the Legendarium following the publication of The Lord of the Rings, revision that elsewhere included additional work on Sauron. Apparently derived from maira (“admirable, excellent, precious”), the name is situated within a broader complex of entries expressing notions of greatness, art-making, service, usefulness, and value. Both “Maia” and “Mairon” are ultimately derived from the same root, suggesting a possible understanding of the pre-corrupted Sauron as in some way exemplary of his own order. The name is notably distinct from the names of most of the other Ainur, the majority of whom are named for particular domains of Creation with which they are associated (weeping, weaving, invention, birds, etc.); “Mairon” (“The Admirable”) is more closely aligned with Melian’s Quenya name “Melyanna” (“Dear Gift”) as both names suggest an implied “other.” Ultimately, the name “Mairon” is meaningful to a reading of Sauron and fits smoothly into a larger pattern of associations of the character with the notions of seeing (or not), being seen (or not), and how one is seen (or how one sees the self)
