Quantum Mechanical Insights Into Heterogeneous Surface Reactions In Chemical Vapor Infiltration, Atal Bhowmik

UTC Spring Research and Arts Conference

This study investigates the decomposition mechanism of Methyl trichlorosilane during Silicon Carbide (SiC) deposition during Chemical Vapor Infiltration (CVI). High-performance applications require SiC-based ceramic matrix composites (CMCs); however, producing them presents difficulties due to limited deposition rates, high energy consumption, and uneven coatings. To overcome these challenges, the mechanism of SiC formation must be understood completely. Modeling surface reactions of MTS decomposition on the SiC substrate using density functional theory (DFT) calculations with the Vienna Ab initio Simulation Package (VASP) is the key point of current research. By focusing on the adsorption, reaction, and desorption mechanisms that control SiC development, …

Modeling The Dynamics Of User Adoption And Abandonment For A Single Product, Uyen Nguyen

UTC Spring Research and Arts Conference

We introduce a compartmental differential equation model to study the dynamics of user adoption and abandonment for a single product. The model integrates two forms of abandonment: infectious, driven by user interactions, and non-infectious, prompted by external influences. Notably, the infectious abandonment coefficient varies linearly with the number of previous users. We investigate the existence of equilibria of the model and derive the threshold quantity ℛ0. The user-free equilibrium is always present, and its stability is analyzed under the condition ℛ0 < 1. Moreover, a user-prevailing equilibrium does not exist when ℛ0 ≤ 1, but at least one user-prevailing equilibrium is guaranteed when ℛ0 > 1. We further characterize conditions for multiple equilibria and various bifurcations, including saddle-node, 𝑆-shaped, and Hopf bifurcations, and formulate …

Effects Of Aerobic Exercise On Physical Fitness In Obesity Using Fox Vs. Tanaka’S Maximum Heart Rate And Percentage Vs. Karvonen Methods, Maninthorn Rugbumrung, Tavarintorn Rukbumrung, Sittiwit Impanya, Adison Thurayot

International Journal of Exercise Science

International Journal of Exercise Science 18(8): 695-711, 2025. The intensity of aerobic exercise is influenced by maximum heart rate (MHR), which can be assessed through an incremental exercise test. However, this method requires specialized equipment and a level of fitness that individuals who are sedentary or overweight may lack. Therefore, estimating MHR using formulas is essential. Various methods exist to calculate MHR, but their effects on fitness in obese individuals remain unclear. This study aimed to investigate the effects of aerobic exercise using different intensity calculation methods, specifically comparing Fox's and Tanaka's maximum heart rate (MHR) equations, as well as …

Coaching Bilingual Speech-Language Student Clinicians And Spanish-Speaking Caregivers To Use Culturally Adapted Ndbi Techniques For Autistic Preschoolers, Richelle R. Mcguire

Speech and Hearing Sciences ETDs

This study used a cascading coaching model to train bilingual speech-language pathology graduate students and Spanish-speaking caregivers to implement naturalistic developmental behavioral intervention (NDBI) strategies with autistic preschoolers. Two triads, each including a student clinician, minimally vocal child with autism, and caregiver, participated. A monolingual instructor coached student clinicians in culturally adapted NDBI techniques, who then coached caregivers in Spanish. A mixed methods approach evaluated outcomes through single-case experimental design and qualitative interviews. All adult participants increased their use of targeted NDBI skills, with large to very large effect sizes. Qualitative findings suggested areas for improvement (e.g., need for more …

Challenging The Universality Of Poplack’S Syntactic Constraints: Insights From Arabic-English Code-Switching Among Saudi Arabian Women, Sharifa Bahri

Linguistics ETDs

This study investigates the applicability of Poplack's (1980) syntactic constraints, the free morpheme constraint and the equivalence constraint, to Arabic-English code-switching among Saudi Arabian women. Based on 886 intra-sentential code-switching utterances drawn from naturalistic podcast speech, the analysis reveals substantial violations of both constraints: 306 utterances (34.5%) violated the free morpheme constraint, and 601 utterances (67.8%) violated the equivalence constraint, occurring across a wide range of syntactic categories. While violations of the free morpheme constraint were exclusively unidirectional, involving Arabic bound morphemes attached to English free morphemes, equivalence constraint violations were bidirectional, though predominantly shaped by Arabic grammar. Crucially, many …
