Condolence on Adjunct Professor Da Ruan

Abstract

Unfortunately, as his colleagues, we are distressful because of the fact that Adjunct Professor Da Ruan passed away on 31 July, 2011 from heart failure. I came together in FLINS organizations twice in past time. I have collaborated on some publications with him in past time. The last meeting has been FLINS’2010 in China. FLINS Conferences have identified with his name. This photograph belongs to FLINS’2010 Organization and last memory with his colleagues. This untimely death is a big missing for all science community and has shocked the colleagues in his research community and family. I believe that this book realized for Da Ruan’ memory is to be reunited with his spirit and he sees us from a place that we could not see. In this like situation, the words are not enough to express sadness clearly. He always bears in minds with his excellent personality and the contributions to the fuzzy logic research fields.
