6月17日，在临潼校区bevictor伟德楼419学术报告厅bevictor伟德邀请美国田纳西大学李虎生教授做了主题为“Information Efficiency and Gleaning in Cyber Physical Systems: From Maxwell's Demon to Millimeter Wave”的学术报告会。本次报告由bevictor伟德副经理张蕾副教授主持，bevictor伟德部分教师和2018级研究生共100余人参加。

会议伊始，李虎生教授介绍了在田纳西大学的学习生活。紧接着，李虎生教授首先讲到物理网络系统中信息的效率和收集问题。他把控制器看作是决定系统熵的麦克斯韦妖控制器，分析如何从传感器传递外部信息来降低系统的熵。重点分析了有限状态系统和连续状态系统降低熵的信息效率问题。最后讨论了如何利用5G系统中的毫米波通信进行传感以及5G毫米波最近的科研成果和未来发展方向。

在交流提问环节，李虎生教授结合自己的科研经历，对员工提出的5G通信技术的问题进行了耐心详细的解答，现场气氛热烈。

此次学术报告会在同学和老师热烈掌声中顺利结束。通过与校外优秀学者的交流，不仅拓宽了师生们的学术视野，更为师生的学术研究提供了新的视角和思路，营造良好的对外交流与学习氛围。（撰稿：行露，审核：张蕾）
