With the reduction of space between ticket machine and exit, the visibility would further become poorer.
Thus in practical projects, the location of the ticket machine should be arranged reasonably through the data verification program

The PLC implements the corresponding control, state monitoring and data collection.
Because the transmission reduction (i) is 4.9 and the transmission efficiency (η) is 0.89, the result of the motor’s speed (n), torque (M) and power (P) as follows

Infrared image preprocessing and fault diagnosis
Different types of electrical equipment have different overheating fault temperature, so we need to extract infrared image edge features to determine the electrical device type, However, electrical equipment often run in harsh and complex natural environment, coupled with the camera itself performance factors and the noise introduced in the acquisition, that will affect electric equipment ontology features extraction, Therefore, we first need to preprocess the image to enhance the contrast, noise reduction and enhanced body image characteristics.
Tab.2 The relative temperature difference value of different images environment temperature equipment normal temperature maximum temperature region The relative temperature difference value of overheating areas Fig 4(a) 16 27 116 89% Fig 4(c) 17 31 110 85% By comparison with the data in Table 1, 89%80% and 85%80%,All electrical equipment overheating fault occurs in Fig 4(a) and Fig 4(c), we need to repair or replacement them.

The results analyzed by using Signal to Noise Ratio (S/N ratio) terms
In detailed explanation, S/N ratios is help in prediction the optimum result besides improve the quality via variability reduction and improved the measurement based on repetition [4].
Results and Discussions Figure 1: Main effect plot (data means ) Signal To Noise Ratio of 0.55 powder loading By referring the figure 1 above, the optimize variable of higher green strength for injection part with powder loading 0.55 were obtained.

Tyrosine kinase inhibitors with urea fragment
Synthesis of 3-arylurea-5-fluoroindolin-2-one derivatives (6a-p)
In library synthesis, the 3-arylurea-5-fluoroindolin-2-one derivatives (6a-p) was prepared by three steps including oximation, reduction and condensation with arylamine (5a-p) with 5-fluoroisatin as the starting material.
Activity data in vitro showed that antitumor activities of 6a, 6h and 6j are better than others.
