Sensor signals were received and tool wear was predicted in the local system using an ART2 algorithm, while the monitoring result was transferred to the remote system via intemet. The monitoring system was installed at an on-site machine tool for monitoring three kinds of tools cutting titanium alloys, and the tool wear was evaluated on the basis of vigilances, similarities between vibration signals received and the normal patterns previously trained. A number of experiments were carried out to evaluate the performance of the proposed system, and the results show that the wears of finishing-cut tools are successfully detected when the moving average vigilance becomes lower than the critical vigilance, thus the appropriate tool replacement time is notified before the breakage.展开更多

Methods： A total of 60 LPE patients were randomly divided into treatment（QSF） and control（dapoxetine） groups. The treatment group received QSF twice a day and the control group received dapoxetine 1 to 2 h prior to planned sexual intercourse for 4 weeks. The outcomes included intra-vaginal ejaculation latency time（IELT）, premature ejaculation diagnostic tool（PEDT）, clinical global impression of change（CGIC）, scores of Chinese medicine symptoms（CMSS）, sex life satisfaction（SLS） and adverse events（AEs）. Results： In the treatment group, the median IELT was 3 min vs. 1.5 min before and after treatment（P〈0.05）. PEDT in the treatment group was reduced to 11.76±1.68 from 15.83±2.30 after treatment（P〈0.05）. Besides, patient＇s SLS was improved from 1.30±0.05 to 6.30±0.04（P〈0.05）, and spouse＇s SLS was increased from 1.30±0.08 to 6.10±0.06（P〈0.05）; CMSS was decrease from 14.86±3.02 to 9.62±2.87（P〈0.05）. In addition, no significant AE was observed in both groups. Conclusion： QSF may be effective and safe on LPE patients with Gan depression and Shen deficiency syndrome.展开更多
