Feedback control for drying Zelkova serrata using in-process acoustic emission monitoring

If internal stresses could be monitored, they might warn that drying defects are about to occur. Checking caused by drying stresses can be regarded as the source of acoustic emissions that are premonitory symptoms of fracture. The rate of acoustic emission depends on drying conditions. This paper describes a preliminary experiment to determine the primary parameter for controlling wood drying and furthermore demonstrates a feedback control for drying * 2Zelkova serrata*1 discs through in-process acoustic emission monitoring. -- AATA
