Abstract.A simple yet accurate model is developed for the dynamical simulation of profile-modified gears, considering the effects of progressive tooth engagement, stiffness, elastohydrodynamic lubricant film formation and hysteresis. The real path of contact, stiffness and elastohydrodynamic lubricant film thickness are calculated for various operating conditions and the results are input to the dynamical simulation, resulting in a prediction of the dynamic transmission error.
Literacy support in an EMI university in Central Asia (CA) helps students with the challenging linguistic demands of tertiary study in a second (foreign) language (L2). As Kazakhstan's post-Soviet education system (Yassukova, 2020) lacks significant first-language (L1) reading-to-write education (Keck, 2014; Friedman, 2019), English L2-literacy development has become even more difficult when compared to other regions of the world. Students’ literacy capabilities need to be investigated by L2-literacy tutors in order to scaffold learning better. Questions emerge as to whether it would help that the tutor had developed her L1 literacy through the same (but chronologically-earlier) system. To unpack this question, research can draw on perspectives in language socialisation (LS) (Duff, 2012), which sees learning environments as dynamic socially/culturally situated processes. To this end, this study looks at one L2-English literacy tutor's (author 2) experiences in a tertiary Foundation writing course. The goal was to see how the tutor’s interpretations of classroom literacy problems could inform the teaching of low L1-literacy students’ writing and metalanguage. For this purpose, we studied the reflective journaling (Burton, 2005) of the tutor who wrote reflective journals during a semester-long course in early 2020. The findings indicate that reflexivity can help a tutor find solutions, and that a similarity of background seems to help a local literacy tutor understand, and respond to, many of their students’ needs.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
