Design Modeling And Cfd Simulation Of Parallel Plate–Fin Heat Sink Under Natural Convection, Tue Duy Nguyen, An Van Vo, Tam Thanh Bui

Makara Journal of Technology

The lifetime of electronic devices strongly depends on the junction temperature. Heat sinks are a good choice for dissipating heat because of their enhanced heat transfer areas. Plate–fin heat sinks are commonly used for electronic components because of their simple construction. Recently, computational fluid dynamics (CFD) software, such as Ansys Fluent and OpenFOAM, has been widely used and has provided effective results. Autodesk CFD is a powerful simulation tool; however, its use in heat sink research remains relatively uncommon. In this study, two plate–fin heat sinks with heights of 30 and 50 mm were first designed using heat transfer equations …

Unravelling Dynamics And Connectedness: Distinguishing The Influence Of Sustainable Finance And Artificial Intelligence On Energy Sustainability In China, Chi Wei Su, Meng Qin

Bulletin of Monetary Economics and Banking

This article examines the significant roles of sustainable finance and Artificial Intelligence (AI) in advancing China’s energy sustainability by employing the TVP-VAR-SV model to track dynamic interactions among the Green Bond Index (GBI), New Economy Index (NEI), and Energy-related Uncertainty Index (EUI). Findings indicate that both GBI and NEI reduce EUI, with GBI exerting a stronger influence due to its direct link to sustainable finance, underscoring its role in mitigating energy market uncertainties. EUI, however, negatively affects GBI, revealing that high energy uncertainty may impede sustainable finance progress. Interestingly, EUI has a mixed effect on NEI, suggesting that energy uncertainties …

Michigan Tech Publications

Fibre-reinforced polymeric composites utilized in aerospace settings, experience varying environmental conditions throughout their operational lifespan. The major factors that can have adverse effects on their long-term performance are water and temperature. The present study investigates how the determinants such as water and temperature impact the structural integrity of plain weave woven carbon/epoxy laminated composites and further categorizing them into compacted and non-compacted groups. The compacted group involves in-process compactions during composite lay-up and the use of bleeders/breathers around the laminate, whereas the non-compacted group lacks these procedures. Specimens comprising twelve plies are created and submerged in water heating chambers set …

Foreign And Heritage Language Learners’ Pragmalinguistic Choices In Russian Imperatives, Marina Tsylina, Anna Mikhaylova

Russian Language Journal

This experimental study examines the pragmalinguistic knowledge of both heritage and foreign language learners of Russian. Specifically, it focuses on how learners interpret the appropriateness of aspectual forms of Russian imperatives in given contexts. Due to limited exposure to authentic input, foreign language learners (FLLs) often face challenges in using pragmatically appropriate language. This study demonstrates that although heritage language learners (HLLs) are exposed to the language from birth, their knowledge of Russian imperatives may not fully align with that of monolinguals. The study participants included FLLs (n = 30), HLLs (n = 10), and monolingual speakers of Russian (n …

Glitching Mayakovsky: Teaching The Accidental Poetry Of Machine Learning, Carlotta Chenoweth

Russian Language Journal

In this article, I seek to build on recent scholarship investigating the aesthetic status of AI-generated objects and the creative potential of machine learning by asking how AI glitches can be productive, both poetically and pedagogically. The report outlines an activity I designed for an undergraduate Soviet literature survey course. For this activity, I ask students to work in small groups and generate their own pseudo-Mayakovsky poem using ChatGPT. After sharing the poems, we discuss questions including the following: in what way can Mayakovsky be considered the “author” of these poems? Does this constitute a new literary genre or form? …

"In 50 Words Or Less": Using Ai To Modulate Target Proficiency Levels In The Russian As A Foreign Language Classroom, Alexander M. Groce

Russian Language Journal

This paper proposes to look at methods for integrating artificial intelligence (AI) into the upper-level Russian as a foreign language (RFL) classroom in activities where variable search terms are used to modulate target proficiency levels according to the ACTFL scale. Specifically, this paper relies upon a series of classroom-based activities that employed AI technology to parse the short stories of Anton Chekhov. While employing some simple methods governing AI search terms can help to create a usable database of sample texts at varying proficiency levels, problems of machine language inherent to emerging generative AI still need to be addressed and …

Introduction To The First Thematic Issue: Artificial Intelligence (Ai) & Machine Translation In The Teaching Of Slavic Languages And Literatures, Liudmila Klimanova

Russian Language Journal

This editorial introduction frames Russian Language Journal’s first thematic issue on artificial intelligence (AI) and machine translation in the teaching of Russian and other Slavic languages, literatures, and cultures. It argues that the rapid spread of large language models makes AI impossible to treat as an optional add-on, pushing educators to revisit authorship, genre, literacy, and assessment while avoiding both moral panic and “quick-fix” approaches. The article synthesizes contributions that (1) integrate chatbots into genre-based writing and conversational practice while emphasizing critical AI literacy; (2) design context-aware conversational agents for Russian and Bosnian/Croatian/Serbian, noting pedagogical benefits alongside risks such …
