This paper chiefly introduces the model of Video Conferencing System, H.323 standard of ITU- T and RTP/RTCP protocol, and realizes a WAN- Oriented Video Conferencing System—VCSW (Video Conferencing System on WAN). In VCSW, RTP/RTCP pro- tocol is used for transporting media data and video conference on WAN can be established, so VCSW has abroad application scope. This paper stresses analyzing RTP/RTCP protocol, realizes it and modifies some details of it according to our device condition: re- duces some fields of RTP and RTCP header, removes some information managed by RTP/RTCP. Consequently in testing of lab, good effect is achieved.

高效准确的短期电力负荷预测对提升新型电力系统经济运行十分重要。针对极端天气场景下负荷预测数据量较少、随机性较强的特点,提出一种基于张量低秩补全算法的短期负荷预测模型,并选取极端高温场景展开研究。首先,给出极端天气定义,并基于改进型炎热指数和气温两项指标进行数据筛选;其次,提出一种基于张量的负荷数据补全模型,补全缺失数据;然后,通过Pearson相关性分析筛选输入特征量,构建基于长短时记忆(long short term memory, LSTM)网络和粗糙集理论(rough set theory, RST)的LSTM-RST短期负荷预测模型;最后,以苏州某地实际负荷数据设置算例进行验证,仿真结果表明,所提短期负荷预测方法具有较高的准确性。

On October 5th, 2020, Drs. Harvey J. Alter, Michael Houghton and Charles M. Rice were rewarded with Nobel Prize in Physiology or Medicine for "the discovery of hepatitis C virus(HCV)". During the past 50 years, remarkable achievements have been made in treatment of HCV infection: it has changed from being a life-threatening chronic disease to being curable. In this commentary, we briefly summarized the milestone events in the "scientific journey" from the first report of non-A, non-B hepatitis and discovery of the pathogen(HCV) to final identification of efficacious direct-acting antivirals. Further, we address the challenges and unmet issues in this field.
