In this work [1], we investigate electron emission from vertically well-aligned single layer graphene inside a gap with an applied voltage. By considering electron traveling through an internal time-dependent potential barrier on the planar surface of the graphene sheet and then through an edge barrier, the current density is calculated. It is found that the over-barrier electron emission is the main...
Prior knowledge in concept acquisition among students is an important issue. Traditional studies on prior knowledge generation during learning have focused on extracting sentences from reading materials that are manually generated by website administrators and educators. From the reports of previous studies, tag-based recommendation and assessment has been recognized as being an effective approach...
CABAC is the entropy coding method adopted in H.264/AVC main profile. RDO is the mode decision method commended by JVT, which can improve the performance of encoder markedly. However, the computation complexity of video encoding increases drastically. In this paper, we propose a novel fast intra-mode decision algorithm for H.264, based on transform-domain bit-rate estimation technique, using the estimated...
