Mechanical Vibrations And Damping – Structural Analysis, Kelsey Hunsicker, Sarah Kraus, Sophia Muller Martinelli De Souza

Discovery Day - Daytona Beach

Mechanical Vibrations are crucial in understanding and structural analysis of engineering systems such as bridges and airplane wings. If not considered, these vibrations can lead to structural fatigue or failure. By using differential equations, structural vibrations will be examined. Researching the different kinds of vibrations and damping will help to find the vibration behavior of the system. For example, a mass-spring damper system will use second-order linear differential equations. The systems model can be shown to be underdamped, overdamped, or critically damped. These will compare the amplitudes and oscillation differences between the systems by using computational code. Analyzing these differences …

Numerical Investigation Of The Nonlinear Simple Pendulum And The Dependence Of Oscillation Period On Initial Angle, Kelly Wold, Aidan Hart, Patrick Gilliam

Discovery Day - Daytona Beach

Numerical Investigation of the Nonlinear Simple Pendulum and the Dependence of Oscillation Period on Initial Angle examines how the oscillation period of a simple pendulum varies with initial angular displacement and evaluates the accuracy of numerical methods in capturing this behavior. In classical treatments, the small-angle approximation simplifies the governing differential equation and predicts a constant period independent of amplitude; however, this assumption breaks down for larger angles, where the system exhibits nonlinear dynamics. The objective of this project is to model the full nonlinear equation of motion and quantify how the period depends on initial conditions. To achieve this, …

Engineering Path Trajectories With Gravitational Fields, Eliane Dean, Aidan Hart, Isabel Noot, Nathan Browning, Valeria Villazon Fito

Discovery Day - Daytona Beach

This project explores how vector calculus concepts play a role in aerospace engineering though spacecraft trajectory design. In particular, the notion of vector fields is used to model the gravitational force, whose work done is expressed through line integrals. By taking the curl of the gravitational field and showing it is zero, the field is recognised as conservative, implying that the work done by gravity is path independent. This property is conceptually linked to gravitational potential energy and the principle of energy conservation. The results are then applied to spacecraft motion, where engineers use energy-base methods to determine efficient trajectories …

Visualizing The Invisible: Simulating Electromagnetic Field In 3d Space With Matlab, Aashman Gupta, Eliane Dean, Riley Esperanca, Hailey Grabinski, Jacob Summerhays, Ameya Sute

Discovery Day - Daytona Beach

Electromagnetic field behaviours in free space are defined by Maxwell’s Equations, which couple the temporal and spatial variations of electric and magnetic fields through partial derivatives. These derivatives quantify the rate of change of each field’s vector component with respect to position and time in a 3D lattice, forming the basis for numerical field analysis. This research will develop a mathematical and computational framework using multivariable calculus to model, simulate, and visualize electromagnetic wave propagation in free space using MATLAB. Gradient, divergence, and curl operations are implemented to compute local field variations and energy transfer. The resulting data are used …

Simulating Pacemakers And Heartbeat Recovery Through Mathematical Modeling, Thomas Estrada, Jayla Edwards

Discovery Day - Daytona Beach

Title: Simulating Pacemakers and Heartbeat Recovery Through Mathematical Modeling   This study utilizes the Fitzhugh-Nagumo model to simulate cardiac electrical activity and the regulatory role of pacemakers through ordinary differential equations (ODEs). By defining the rate of change for membrane voltage, 𝑑𝑣/dt, and a recovery variable, 𝑑𝑤/dt, the model captures the heart's excitability and resting states. Central to the analysis is the stimulus current parameter, which represents the "kick" provided by a pacemaker to correct flatline conditions or weak heartbeats. Using Euler’s method for numerical integration, the research compares unstable cardiac rhythms against corrected periodic oscillations. Additionally, the project implements vector …

Eugenics Ties With Nature, Samuel Griffin

History in the Making

While Eugenics and the American West have been thoroughly studied, the connection which highlights the continuous pattern of white supremacist ideals between the two has not been examined sufficiently. Drawing on writings from Frederick Jackson Turner, John O’Sullivan, and research by Douglas Sackman. This article articulates how the 19th-century American viewed nature as something to conquer, and those who did not share this view were deemed inferior. Additionally, this work analyzes Alexandra Minna Stern’s Eugenic Nation alongside Luther Burbank’s and Dr. John Kellogg’s personal writings to highlight California’s support and participation in eugenics. By analyzing Burbank’s and Kellogg’s writings, the …

Photo Essay: Affective Infrastructures Of Migration In Mindanao, Philippines, Marion Breteau

Asia Pacific Perspectives

This photo essay explores the affective infrastructures that sustain and shape return migration between the Philippines and the Arab Gulf states. By affective infrastructures, I refer to the material, moral, economic, and relational arrangements that make migration possible, and that continue to structure life after return. Rather than addressing migration as a linear trajectory (departureemployment-return), the essay presents it as processual, and encrypted in houses, debts, bodies, aspirations, and memories. The fieldwork is grounded in Tampakan, a rural municipality in South Mindanao, a region that contains one of the largest Filipino emigration basins to the Gulf. Illustrating how return reshapes …

Exploring The Motivations Of Undergraduate Sport Management Students, Kyle J. Brannigan, Tyler J. Hajek

The COSMA Journal

This study explored the motivations of undergraduate sport management in four university programs. Convergent mixed-methods research through the theoretical framework of Self-Determination Theory was incorporated with an adapted questionnaire of the Academic Motivation Scale and semi-structured interviews through Thematic Analysis. Ninety-six surveys with nine interviews were deemed usable across four regionally focused, vocationally minded, and accessible universities. Overall, students reported higher levels of extrinsic motivation than intrinsic motivation. The findings suggested intrinsic motivation to know and extrinsic motivation through regulation for identification scored highest with the participants. No significant differences were found between classes and ethnicities. However, male students experienced …

Revisiting The Flutie Effect: The Impact Of Collegiate Athletics On College Choice, Robin Hardin, Michelle L. Childs, Win G-Y Koo

The COSMA Journal

This study revisits the Flutie Effect by examining factors that influence a student’s college choice which includes the role of athletics and its brand. The study assessed items related to academics, interpersonal influences, campus culture, and athletics through a survey of first-year students. An exploratory factor analysis produced a seven-factor model explaining 71.51% of the variance. The strongest factor was emotional and behavioral identification with university athletics, reflecting fandom, affiliation, and pride in athletic success. Athletics significantly influenced college choice, but their impact extends beyond athletic success to include broader dimensions of branding, fandom, and affiliation. For institutions seeking to …

Simulations Of Phugoid Motion Of Jal 123, Dereth J J. Drake Scheuermann

Georgia Journal of Science

Airplanes rely on a balance between the four forces of flight: lift, weight, thrust, and drag. If these forces are balanced, the airplane will remain stable. However, if structurally or systematically compromised, the motion can rapidly become unstable. In the aviation industry, mistakes in repairs and aircraft design can lead to accidents causing the loss of life in some cases. In this article, we will be analyzing what happened 70 Japan Airlines flight 123 and how the flight’s motion deteriorated due to a defective repair. More specifically, we will discuss the aerodynamic effects of phugoid motion and how it developed …

Toward A Standard Of Identity In Ai Interaction, Brian Harber

Defensive Publications Series

Systems are increasingly capable of producing outputs that appear complete and actionable. These outputs are frequently evaluated as though they fully represent the processes that produced them. This paper argues that where identity is not explicit at the interaction boundary, interpretation necessarily relies on inference. Inference enables interaction but leaves residual uncertainty regarding what participated in producing that interaction.

The paper proposes identity as a structural property of interaction rather than an inferred property of behavior or presentation. It defines the interaction-boundary condition under which identity becomes relevant and examines the implications of that condition for evaluation. The contribution is …

Breaking The Parallax: Big Tech In India, Dr. Pratiksha Ashok

National Law School Business Law Review

This paper examines the role of Big Tech in India through the conceptual lens of parallax, understood as the analytical distortion that arises when platform power is assessed from shifting institutional, legal, and geopolitical vantage points. Existing scholarship and policy debates tend to frame Big Tech in India either through Global North regulatory paradigms emphasizing monopoly power, market foreclosure, and the need for ex-ante constraints or through a domestic developmental narrative that positions digital platforms as engines of innovation, inclusion, and infrastructural expansion. This paper argues that neither perspective, taken in isolation, adequately captures the legal and political economy of …

Training And Resources For Clinicians To Reduce Paperwork Burden And Improve Patient Work Capacity Documentation, Emilio Del Toro, Susan Gatti, Jennifer Kimble, Rebekah Lewis, Karen L. Fortuna, Samantha Migdail-Goyette, Gregory G. Morneau, Donald J. Medd, Ricky Snyder, Karen L. Huyck

Journal of Maine Medical Center

Problem: Inadequate patient work capacity documentation by clinicians contributes to health and economic inequity, clinical inefficiency, and worse patient health outcomes. The intersection of an aging workforce and high amounts of work disability presents an opportunity for health systems to integrate occupational health best practices across clinical settings to improve patient health and work outcomes. Clinicians, however, are often unfamiliar with navigating patient work capacity forms to help patients maintain or obtain employment. This knowledge gap further perpetuates work disability.

Approach: To compensate for this gap, we co-created a training for clinicians that integrates didactic learning and supplemental resources to …

Intensification Of Thermal Energy Storage Systems Based On Sodium Nitrate, Hari Suthan V Mr

Theses and Dissertations

Thermal energy storage (TES) systems employing phase change materials (PCM) bridge the gap between thermal energy demand and supply. The low thermal conductivity of sodium nitrate (NaNO3), an inorganic PCM for high-temperature TES systems restricts charging and discharging kinetics, reducing system-level performance. This thesis investigates the intensification of sodium nitrate-based thermal energy storage systems through the incorporation of different classes of additives. Metal oxides (zinc oxide and aluminium oxide) and carbon-based materials (graphene oxide (GO) and expanded graphite (EG)), were incorporated into NaNO3 to improve its thermophysical properties (thermal conductivity, latent heat, specific heat).

Composites were prepared using low-energy ball …
