Accurate detection, classification and mitigation of power quality (PQ) distortive events are of utmost importance for electrical utilities and corporations. An integrated mechanism is proposed in this paper for the identification of PQ distortive events. The proposed features are extracted from the waveforms of the distortive events using modified form of Stockwell’s transform. The categories of the distortive events were determined based on these feature values by applying extreme learning machine as an intelligent classifier. The proposed methodology was tested under the influence of both the noisy and noiseless environments on a database of seven thousand five hundred simulated waveforms of distortive events which classify fifteen types of PQ events such as impulses, interruptions, sags and swells, notches, oscillatory transients, harmonics, and flickering as single stage events with their possible integrations. The results of the analysis indicated satisfactory performance of the proposed method in terms of accuracy in classifying the events in addition to its reduced sensitivity under various noisy environments.

Reading For Pleasure

This study explores how New Zealand primary school students’ experiences of school libraries affected their attitudes towards reading for pleasure once they entered secondary school. Two hundred and seventy-six students in their first year at high school completed a survey asking about their primary school libraries. The students were asked to self-identify as keen readers, occasional readers or non-readers. The results were analysed in a spreadsheet, considering variables such as attitude to reading, former school and family background. The students were mainly positive about their libraries, but were bothered by cramped and noisy environments and books they perceived as babyish. Students from schools with a librarian were more positive about reading for fun than those from schools where the library was not prioritised. Students from a family background where reading was encouraged were more likely to maintain a positive attitude to reading by the time they reached high school.
