In the metallurgical enterprises, there exists a prominent contradiction between the demand of the railway transportation and the EFR (existing facilities of railway). To research on the limit capacity of the EFR, this paper constructed a Multi-Agent model based on the MAS (multi-agent system) theory for the RTS (railway transportation system) in the metallurgical enterprises. Take a steel plant as...
Evaluation of multi-slice CT angiography (MSCTA) and digital subtraction angiography (DSA) was made through the comparison of the two methods in the detection of the blood supply of meningiomas, providing further clues for improved application of MSCTA and DSA in the blood supply of meningiomas. MSCTA is more advantageous in the depiction of three-dimensional relationships between the tumor and peripheral...
An electric car and teeterboard self-balanced system was designed in this paper. The 32-bit ARM chip LPC2138 was applied as the MCU and the stepper motor was used as the driven device for the electric car. The angle signals derived from the AccuStar electronic inclinometer by moving average digital filter helped to accomplish the closed loop digital PID control system and keep the balance of the teeterboard...
