Assessment of sampling variation applets during development

open access: yesTeaching Statistics, EarlyView.
Abstract Concepts relating to sampling variation are known to be difficult for learners in introductory classes. There is some evidence that web‐based visualization tools, or “applets,” may aid the learning of these challenging ideas. Four freely available applets developed at the authors' institution were extensively tested through sessions involving ...

Construction and Application of Online Vibration Frequency Response Analysis Method for Converter Transformer Winding

open access: yesHigh Voltage, EarlyView.
ABSTRACT The harmonic current and vibration of a converter transformer are effective pieces of information for detecting mechanical faults in the winding. In this paper, the ratio of vibration acceleration to the current squared is defined as the vibration frequency response function (VFRF) of the winding, and then, a novel online vibration frequency ...
