A new weighting scheme and discriminative approach for information retrieval in static and dynamic document collections (2014)
Conference Proceeding

This paper introduces a new weighting scheme in information retrieval. It also proposes using the document centroid as a threshold for normalizing documents in a document collection. Document centroid normalization helps to achieve more effective inf...

Assessing the accuracy of loss estimation methods for supercapacitor energy storage devices operating under constant power cycling (2014)
Conference Proceeding

This paper assesses different energy loss estimation methods using the supercapacitor model parameters extracted from the electrochemical impedance spectroscopy (EIS). Two energy loss estimation methods are applied to two similar supercapacitors from...

Do subject specialists produce more useful feedback than non-specialists when observing mathematics lessons? (2014)
Conference Proceeding

Schools, districts and inspectorates routinely use non-specialists to observe lessons for accountability and professional development purposes. However, there is little empirical research on how well non-specialists observe lessons. We describe two p...
