Via-plate interaction can be modeled as lumped circuits for vias and a two-dimensional field problem for the plate domain. The accuracy of the improved intrinsic via model and the conventional physics-based via model is investigated by comparing them with either analytical formula or numerical simulations for a via in a circular plate pair with various edge boundary conditions. It is found that the...
Because of accurate forecasting of tourist arrivals is very important for tourism industry, various tourist arrivals forecasting models have been developed. The aim of this paper is to introduce the basic theoretical principles of electromagnetism-like mechanism (EM) algorithm and design a new neural network model for tourism forecasting which uses the EM algorithm as the learning rule (EMNN). The...
The deficiency of subsidence prediction in steep seam mining by the theory of equivalent effect is analyzed: more than 1/2 area of the subsidence basin is caused by the mining of downhill horizontal seam because of the great difference between r1 and r2; r2 is too small that the sinking curve is almost vertical. According to the characteristic of that mining depth is quite different in steep seam...
This paper reported the latest development of the modal decomposition with T-matrix method for accurate and efficient analysis of coupling of multiple vias in finite-sized multilayered parallel-plate structures. A novel boundary modeling method, named the frequency-dependent cylinder layer (FDCL), is proposed to resolve the open problem of boundary modeling associated with modal expansion methods...
A hybrid scattering matrix method (SMM) and a modal decomposition technique for analysis of signal traces in the power distribution network of an electronic package are presented in this paper. Applying the modal decomposition of the waves propagating inside the power-ground (P-G) planes and the signal traces, the electromagnetic fields can be decomposed into the parallel-plate mode and the transmission-line...
