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 ...
Stability and Convergence of the Two-step BDF for the Incompressible Navier-Stokes Problem The incompressible Navier-Stokes problem is discretised in time by means of the two-step backward differentiation formula with constant step sizes. Existen......

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 ...
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...
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...
For example, the a_{b} and (a)_{{b}} rendering results are completely consistent. Reducing a layer of {}{} can decrease the calculation amount of the model. Another situation is that 𝜓ψ and the rendering result are the same. However, if the former model is adopted, the output ...
After the stress function and its normal derivative on the boundary for the plane problem of exterior circular domain are expanded into Laurent series,comparing them with the Laurent series of the complex stress function and making use of some formulas in Fourier series and in the convolutions,the...
