For recommending effective TCM formula for advantage diseases, Zhou [46] proposed a deep learning network(FordNet) with ReLU as the activation function of convolution layer. In deep learning models with cloud computing proposed by Zhang [45], using Tanh and ReLU activation functions in the model...
1.This paper employ thePECK formulato dicuss the key-factors of shield-tunnelling,proposes a experiential formula about the minimum depth of the covering-layer.本文针对盾构隧道推进中引发的地表沉降采用PECK公式对其影响因素进行了讨论;根据有关规定的的地表不均匀沉降的限值,针对不同的隧道直径提出了上覆土...
ConvolutionKirchhoff's formula is the equivalent to Green's Third Theorem for transient waves, representing the solution of the three-dimensional wave equation in terms of its boundary data. In this classical result two retarded layer potentials appear. We show in this paper a precise description ...
This procedure provides an effective correction similar to the powerful technique for correcting the measured linewidths in Raman spectroscopy where the observed spectroscopic band shape is the convolution of the physical and the instrumental contributions47,48,49. To further justify the effectiveness of ...
2.Firstly,the key technical parameters in prestack time migration byKirchhoff integral methodwere analyzed,including prestack de- noise,amplitude compensation,de-convolution,statics,root- mean-square velocity model building and migration aperture se.表明Kirchhoff积分法叠前时间偏移处理结果包含的地震信息更加...
Before the final ensemble-CNN model was built, the number of the convolution layers in the sub-models was optimized in range 1~5, while the number of filters for each convolution layer was optimized in range (8, 16, 32, 64) by an internal cross-validation procedure. During the parameter...
Due to the different image sizes, GAP is used instead of the FC layer, with the advantage of reducing the number of parameters and receiving features of different scales. The channel weights are multiplied by the feature information of different convolution kernels to obtain the feature vector ...

The evolution of the bubble is solved by the boundary integral method,and the singularity of the double layer potential is eliminated by recasting the principal-value integral of the double-lay. 模拟了近壁、近自由面的水下爆炸气泡的非线性动态特性,假定水下爆炸气泡脉动阶段的流场是无旋、不可压缩...
