It has been shown45–47 that the competition between the Debye length and the characteristic sizes of roughness would modify the Gouy–Chapman result for the diffuse layer capacitance. The limiting value of the capacitance at short Debye length should follow the Gouy result, but with surface area...
The main purpose of padding is to ensure that the sizes of the input feature map and the output feature map are the same. This is achieved by adding pixels of zeros around the outside of the image. As illustrated in Fig. 3.8(b), the size of input image or feature map is 4×4, ...
The x–y robotic spraying technique developed in the Universiti Kebangsaan Malaysia is capable of fabricating various sizes of thickness and porosity of gas diffusion layer (GDL) used in the proton exchange membrane fuel cell (PEMFC). These parameters are obtained by varying the characteristic spray...
X, Y = load_planar_dataset() 1. 使用matplotlib可以将数据可视化: 数据集类似一朵花,有红色(label y = 0)和蓝色(label y = 1)的点构成,我们的目的就是去拟合这个数据。 获取数据的维度: shape_X =X.shape shape_Y=Y.shape m= shape_X[1]#training set size ...
On the suction side of the airfoil, the boundary layer is initially laminar with a boundary layer thickness less than typical hole sizes. Further downstream, the boundary layer will typically transition to turbulence with the transition location and characteristics of the turbulent boundary layer ...
