Discussion on “AC Drive Observability Analysis” [PDF]
IEEE Transactions on Industrial Electronics, 2015 In the paper by Vaclavek et al. (IEEE Trans. Ind. Electron., vol. 60, no. 8, pp. 3047-3059, Aug. 2013), the local observability of both induction machine and permanent-magnet synchronous machine (PMSM) under motion-sensorless operation is studied. In this letter, the "slowly varying" speed assumption is discussed, and the PMSM observability condition ...

Temperature and ac Effects on Charge Transport in Metallic Arrays of Dots [PDF]
, 2003 We investigate the effects of finite temperature, dc pulse, and ac drives on the charge transport in metallic arrays using numerical simulations. For finite temperatures there is a finite conduction threshold which decreases linearly with temperature ...
