Net profit margin (NPM) on total assets is calculated by the proportion of net profit to the average balance of total assets. Data source The data in this research can be mainly classified into two typesFootnote 2. The first one is the panel dataset of 285 prefecture-level cities in China...
The download speeds were calculated by measuring the average download speed experienced by Opensignal users across an operator's 3G and 4G networks. This method factors in 3G and 4G speeds coupled with the availability of each network technology. ...
We cross-validated the automatically calculated slope with the manually calculated slope and found that they are statistically comparable (S5 Fig). Since the automatically calculated slope is less affected through human bias we decided to use this data for our further analysis. ...
The present invention discloses a method based on ETC toll highway road travel speed data calculation method, including: ETC original transaction data preprocessing; link travel speed is calculated based on ETC transactions. 根据计算时间周期内路段ETC数据量大小,分两种情形给出了不同样本量水平下速度的...
As a first tentative value, SRopt/SRth = 1.13, and D1 can be calculated by Eq. (8) and using SRopt instead of SRth. N’ is then calculated, and, consequently, the new SRopt, until convergence, maintaining N constant. Once convergence is reached, the D1/b value is checked and, ...
(φt = φtm) and the angular velocityωd = 0o/s. The maximal winding angleφtmof the threads is calculated by integratingωdfromt1tot2. The lengthls0of the strings used in the experiments was approximately 30 cm. The axial deformationεsof the string was captured by using a...
First, the ARMA model of the raw wind speed data is built, and the Partial Autocorrelation Coefficient (PAC) p of the model is calculated by using Akaike Information Criterion (AIC). Second, the p value is used as the basis for dividing the data set to train SVR for the wind speed ...
When the forest fire spread is simulated by CA, the state of cells at time t is calculated according to the total area and the burned area of cell at the time t [44]. 𝐴𝑡𝑖𝑗=𝑆′(𝑖,𝑗)𝑆(𝑖,𝑗)Aijt=S(i,j)′S(i,j) (5) In Equation (5), the value ...
