Promoting Foreign Language Enjoyment Through Displaying Affiliation in Collaborative Digital Multimodal Composing in Hong Kong ESL Classrooms: Insights From Translanguaging and Transpositioning Perspectives

International Journal of Applied Linguistics, EarlyView.
ABSTRACT Studies on classroom interactions suggest that displaying affiliation through linguistic and multimodal resources could promote positive emotions like enjoyment, thereby enhancing engagement and enthusiasm in second/foreign language learning.

Exploring Chinese International Students’ Intercultural Competence in Australian University Classrooms: Challenges and Opportunities

International Journal of Applied Linguistics, EarlyView.
ABSTRACT With the increasing number of Chinese international students in Australian universities, intercultural competence has become a critical factor influencing their interactions with Australian tutors in university classroom settings. Existing research often examines students’ intercultural competence from a single‐method or single‐perspective ...

Evaluation of Sparse PWM Converter for Switched Reluctance Generator

2005 International Conference on Power Electronics and Drives Systems, 2006
The paper investigates the operation of a novel power converter for the switched reluctance generator. The sparse PWM converters reduce switch count and eliminate the front-end current smoothing inductor which leads to a low cost and small converter.

Design and optimization for the linear switched reluctance generator

2011 4th International Conference on Power Electronics Systems and Applications, 2011
In this paper, a novel double-sided direct-drive linear generator based on switched reluctance principle is proposed. In order to acquire a higher power density, the optimization of structure parameters for the double-sided linear switched reluctance generator (DLSRG) is carried out.

Dynamic simulation model of switched reluctance generator

IEEE Transactions on Magnetics, 2003
This paper deals with a numerical model of the switched reluctance generator (SRG) for use on a general-purpose circuit simulation program "SPICE". In the model, the electric circuit and magnetic circuit are coupled by proper controlled sources. Using the numerical model, we can readily calculate the dynamic behavior of the SRG.

Study on switched reluctance generator

Journal of Zhejiang University-SCIENCE A, 2004
The linear and non-linear math models of the switched reluctance generator (SRG) in generator mode were established in this work. The phase current and energy conversion process during generator operation were simulated by the linear math model. The non-linear math model was used to analyze the characteristics of the SRG operation in self-excitation ...

The modelling and the simulation of the switched reluctance generator

2008 34th Annual Conference of IEEE Industrial Electronics, 2008
This paper presents a new design SRG (Switched Reluctance Generator) that has untraditional pole construction and small coupling due to its magnetic characteristic. Firstly, the dynamic model of the SRG is derived as a magnetic circuit. One of the most important aspects of study for simulating and modelling, is the measurement of the motor parameters ...

Switched Reluctance Starter/Generator

SAE Technical Paper Series, 1992
<div class="htmlview paragraph">This paper describes the characteristics of the switched reluctance motor (SRM) used as a generator. In this mode of operation the SRM is unique in that it does not employ permanent magnets or a field winding on its rotor.
