Emergency braking, the sense of overload valve according to vehicle load and road surface resistance, in a very short period of time to control the brake fluid to front and rear brake pad braking force to bear nearly ideal curve, can effectively prevent skidding and locking to shorten the braking distance, enhanced braking effect.
The paper analyzes the main factors which affect the spacing of urban rail transit stations, studies the trip distance-trip time curves for urban rail transit and bus-route, and points out that the critical distance is the dividing line by which passengers choose urban rail transit or bus-route.
The peak overpressure, impulse, and its positive pressure time vs scaled distance fitting curves of blast wave and TNT, △p_m~(0.742)i_s~(0.258), and impulse equivalent have been obtained.
Following, a experiment has been carried out, the incident waves with a frequency band of 200kHz-350kHz are used to the experiment, and a series of peak value-time curves are drawn each 10kHz, corresponding time are found through fitting peak value, thus the position of the defect is calculated accurately. The application of awl-shaped sensor head in the heat change water pipe experiment indicates that the ultrasonic guided waves may transmit nearly 50 meters in the pipe, which is not influenced by the elbows and makes it possible to test defects in long distance and large-scale. The water-load pipe experiment indicates that the displace and energy maybe leakage at the near-surface, which is significant for the further research.
For distributive mixing ability, KB120/120 and FTX showed excellent performance on distributive mixing ability, because they had the greatest backflow and the widest distance between inflexions of RTD curve respectively.
However, one side effect of this approach is that the trace of an object in the time-distance space is a curve.
The relation between the escape time of a point and the distance from it to the invariant curve is also discussed.
According to control principle of elevator and its velocity curve generation method, a sine velocity curve based on time and distance is designed. An elevator monitoring system is developed.
Adhesion on the train, deceleration forces, braking time and braking distance is calculated in the paper. Then deceleration and speed curves, electric air distribution curves during the train braking were obtained.
Due to the impossibility to compute the exact length of NURBS curve through integration in a short time, it is very difficult to get the deceleration distance and to forecast the point to begin the deceleration stage in real time.
Curves of raising velocity against up-flow area diameter developed based on the model can describe response rules with the change of parameters, such as substrate concentration, air-lift distance and hydraulic retention time, etc. in reactor.
The decay curves of peak pressure and positive pressure actuation duration with increasing scale distance have been given by the analysis of test results, and the corresponding empirical formulas have been presented.
In this paper, robots paths are approached by B spline through introducing pseudo distance and pseudo velocity variables to parameterize the path. We also use dynamic programming carry out two dimension dynamic optimization and find the time fuel synthetic optimal trajectory for robots.
Second, more recent curves are flatter. A flatter curve means a bigger standard deviation and a wider spread of results.
