Hi Prof. LaiWe are glad to host IEEE Se minar with NTUT library. I really appreciate Prof. Lai would be willing to accept our invitation and we only invite one fellow to this session. In this session, professor might need to prepare the PowerPoint and it will spend about 40 minutes to share your successful experience. For your information, as following website links are topics from other fellows in past three years seminars:2015http://www.hintoninfo.com.tw/IEEE_2015.html2014http://www.hintoninfo.com.tw/upload/ieee/2014/2014_ieee_03.html2013http://www.hintoninfo.com.tw/upload/ieee/02.htm
