Mathematical Modeling, Analysis And Numerical Simulation Of Air Quality Using The Advection-Diffusion-Reaction Equation, Md Timorul Islam

Math Theses

In this thesis, we study an air quality model by using a nonlinear one-dimensional advection-diffusion-reaction system of partial differential equations for NO-NO2-O3 chemical cycle. The model incorporates advection, diffusion, chemical reactions, and source terms, and is formulated based on standard atmospheric chemistry.

We first develop numerical methods to approximate the solutions of the governing equations. Both explicit and implicit finite difference schemes are considered, and the implicit scheme provides approximations without any restrictions on the stability.

The model is then nondimensionalized to identify key parameter combinations governing the system. This leads us to a regime in which the transport and …

Effectiveness Of The Mediterranean Diet For Sustained Weight Maintenance Following Glp-1 Medication Discontinuation: A Longitudinal Prospective Study, Nitya Reddy, Josephine Thomas, Julie Salam

Department of Nutrition Student Projects

Glucagon-like peptide-1 (GLP-1) receptor agonists are effective for short-term weight reduction in adults with obesity, yet weight regain is frequent after discontinued use of the medication. Identifying sustainable dietary approaches that support long-term weight maintenance is imperative. The Mediterranean diet has been associated with improving metabolic health and resistant weight control, suggesting it may be an effective strategy for the transition off GLP-1 therapy. Men and women ages 45-55 that are diagnosed with Type 2 diabetes and receiving GLP-1 receptor therapy are the targets of this study, specifically those who plan to discontinue medication within the next three months. On …

Ensuring Year-Round Fresh Strawberries: A Sustainable Supply Chain Approach, Rizza Panopio Constantino, Leilani De Guzman

Journal of Management for Global Sustainability

This study aims to develop a sustainable and cost-efficient sourcing strategy for fresh strawberries used in the strawberry jam production of Tantamco’s Fine Foods (TFF), a well-known pasalubong (locally produced gift food items commonly brought home from trips) shop in Baguio City, Philippines. Specifically, the study seeks to identify the key factors causing price volatility and supply instability and determine strategic interventions that can ensure a more stable, affordable, and year-round strawberry supply. Employing a qualitative research approach, the researchers conducted in-depth interviews with strawberry farmers, market vendors, traders, fellow jam producers, and the company’s procurement personnel. The findings reveal …

Negotiating Digital Identities With Ai Companions: Motivations, Strategies, And Emotional Outcomes, Renkai Ma, Shuo Niu, Lingyao Li, Alexander Hirth, Ava Brehm, Rowajana Behterin Barbie

Computer Science

AI companions enable deep emotional relationships by engaging a user's sense of identity, but they also pose risks like unhealthy emotional dependence. Mitigating these risks requires first understanding the underlying process of identity construction and negotiation with AI companions. Focusing on Character.AI (C.AI), a popular AI companion, we conducted an LLM-assisted thematic analysis of 22,374 online discussions on its subreddit. Using Identity Negotiation Theory as an analytical lens, we identified a three-stage process: 1) five user motivations; 2) an identity negotiation process involving three communication expectations and four identity co-construction strategies; and 3) three emotional outcomes. Our findings surface the …

Creating Disability Story Videos With Generative Ai: Motivation, Expression, And Sharing, Shuo Niu, Dylan Clements, Hyungsin Kim

Computer Science

Generative AI (GenAI) is both promising and challenging in supporting people with disabilities (PwDs) in creating stories about disability. GenAI can reduce barriers to media production and inspire the creativity of PwDs, but it may also introduce biases and imperfections that hinder its adoption for personal expression. In this research, we examine how nine PwD from a disability advocacy group used GenAI to create videos sharing their disability experiences. Grounded in digital storytelling theory, we explore the motivations, expression, and sharing of PwD-created GenAI story videos. We conclude with a framework of momentous depiction, which highlights four core affordances of …

When Generative Ai Is Intimate, Sexy, And Violent: Examining Not-Safe-For-Work (Nsfw) Chatbots On Flowgpt, Xian Li, Yuanning Han, Di Liu, Pengcheng An, Shuo Niu

Computer Science

Content Warning: This paper contains sexually explicit and violent images and text. User-created chatbots powered by generative AI offer new ways to share and interact with Not-Safe-For-Work (NSFW) content. However, little is known about the characteristics of these GenAI-based chatbots and their user interactions. Drawing on the functional theory of NSFW on social media, this study analyzes 376 NSFW chatbots and 307 public conversation sessions on FlowGPT. Findings identify four chatbot types: roleplay characters, story generators, image generators, and do-anything-now bots. AI Characters portraying fantasy personas and enabling hangout-style interactions are most common, often using explicit avatar images to invite …
