Abstract The Swiss-type lathe is a specialized turning machine of Swiss-origin with wide range applications across the precision machining industry. Its unique features enable it to mass produce parts at high speeds and precision. However, complex non-symmetric structure tool makes particularly susceptible adverse effects thermal influences. These internal external influences cause an offset ce...

In this study, the typical application of supports and hangers in water supply drainage system, ventilation smoke extraction duct system electric or optical fiber has been collected investigated, order to understand fire resistance used for service installation China, further optimize testing evaluating method these products. A series resistant different working condition have carried out effec...

The commonly used working condition recognition method in the mineral flotation process is based on shallow features of froth images. However, images frequently have an excessive amount redundant and noisy information, which has impact effect prevents from being effectively optimized. Therefore, a for deep feature fusion densely connected network decision tree (DSFF-DenseNet-DT) proposed this p...
