Accessing Young Children’s Ideas about Energy [PDF]
Education Sciences, 2021 We present a multi-method design for elucidating young, mostly illiterate children’s (grades 1 and 2 of Swiss elementary school, ages 6–8) ideas about energy. The design uses semi-structured interviews and video recordings as the main methods of data generation and collection, respectively.

Vector control strategy of a T-type three-level converter driving a switched reluctance motor
Chinese Journal of Electrical Engineering, 2019 A novel 12 voltage vector control strategy for switched reluctance motors (SRM) with a T-type three-level converter is proposed in this study. Based on a causal analysis of torque ripple under the control of conventional six voltage vectors, six new ...
