Linearity and synchrony

Abstract

In this paper we propose new quantitative metrics that express the characteristics of current general practices in slidebased presentation methodology. The proposed metrics are numerical expressions of:`To what extent are the materials being presented in the prepared order?' and`What is the degree of separation between the displays of the presenter and the audience?'. Through the use of these metrics, it becomes possible to quantitatively evaluate various extended methods designed to improve presentations. We illustrate examples of calculation and visualization for the proposed metrics.

Possible origin of double-peak emission in InGaN quantum wells on m-plane free-standing GaN substrates

“…However, any apparent irregularities, such as In-compositional separation or extended defects, cannot be observed in our m-plane InGaN quantum well (QW) samples that show the double-peak emission. 9) These results show that phase separation or extended defects are not the origins of the double-peak emission. Valence band splitting is also a possible candidate for the origin, because two bands are closely located at the top of the valence band in InGaN-QWs, 11) and the two peaks can correspond to the emission peaks from the two valence bands.…”

“…From these results, we are now considering that the decrease in emission intensity correlates with the double-peak behavior. 9,10) Then, we performed structural characterizations such as transmission electron microscopy (TEM) and threedimensional (3D) atom probe to investigate the origin of the double-peak emission. However, any apparent irregularities, such as In-compositional separation or extended defects, cannot be observed in our m-plane InGaN quantum well (QW) samples that show the double-peak emission.…”
