The steering behavior of lane change during overtaking on the freeway is experimentally investigated based on a six DOF moving-based driving simulator. 12 experienced participants are involved and instructed to overtake leading vehicles in specially designed scenarios, and their first lane changing of the overtaking is analyzed. The influence of type and speed of leading vehicle on steering behavior...
Saddle point algorithm is a new fast iterative method for linear programming, the program based on this algorithm has been widely used in many fields and shows better performance than other public domain programs. Sensitivity analysis is used to determine how the optimal solution is affected by changes, within specified ranges, in the objective function coefficients or the right-hand side values....
When detecting axially oriented defects in pipelines by circumferential magnetic flux leakage(MFL) internal inspection technology, the key is how to process the MFL detection signals. MFL signal processing methods are implemented, such as detection signal interpolation smoothing method, the amendment method of detection singular points, defect-free magnetic flux leakage signal compensation method,...
Monitor and analysis of power system is very important to guarantee power quality. Accidents often occur because of bad power supply quality. So power department and user of electric power all want to improve power quality. Monitor and analysis System of power quality is widely used. The paper monitored fluctuated condition of power quality index by means of method of frequency spectrum analysis based...
The multi-point dynamic-displacement data of structure is an important parameter for structural health monitoring. The difficulties of traditional multi-dynamic displacement measurement are reference point selecting and massive data processing. A novel multi-dynamic displacement measurement system was developed based on digital image processing technology. The calibration method based on surface fitting...
Biomass distribution, morphological and growth characteristics of reeds under different irrigation modes were studied, provided secondary effluent from papermaking wastewater as the irrigation water. The results showed that irrigation with wastewater can promote reed growth and postpone the total biomass peak, and plant height, total biomass were both prominently higher than control group. Under wastewater...
