Respondents were asked about their willingness-to-travel time (hereafter WTT) after the bird flu outbreak was resolved under the hypothetical situation, given information policies and travel costs. The minimum WTT was designed as “a (1) week” to ensure sufficient planning time for respondents. ...
The time constant Tc = 2 ms is introduced to avoid voltage overshoot, where Ts denotes the sample time. From Equations (3) and (6), the torque and the voltage are determined by the current value, which could be expressed as: y = f (id, iq). The current vector modification strategy ...
N is a normally distributed noise; µ stands for the evaluation actor network. When an action a is selected to act on the environment, the reward r and the next state s′ are subsequently obtained. At this time, experience samples (s, a, r, s′) can be received and stored in the...
Similar to the model of terminal users' temperature, many parameters have influence on the output of CAC, but most of these parameters are invariable for a unique CAC. Based on the above consideration, the time-varying parameter load ratio becomes the key factor in this model. Load ratio is...
The grinding time of different tests is the same, that is 30 s. Therefore, following grinding, the micro textures were soaked in an acetone solution, and the grinding powder was cleaned by an ultrasonic wave. power was 35 W, the scanning speed was 1700 mm/s, and the scanning times were...
