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

In order to develop such principles, this paper analyzes the radioecological situation in the territories of Donetsk and Luhansk regions of Ukraine for rapid and high-quality environmental cleanup and rehabilitation of areas with detected critical levels of environmentally hazardous pollutants. In order to quickly obtain fundamentally new environmental information, it is necessary to conduct multi-parameter, high-precision integrated monitoring of the Earth’s geospheres based on the latest methods and equipment for ground and remote environmental measurements, and new methods and technological means of clean, environmentally safe processing and final disposal. As the most appropriate technology, we propose mobile installations for plasma-chemical pyrolysis of medical waste directly at the place of its generation.展开更多
