Along with emergency of the Yangtze River economic belt development strategy, Chongqing and Luzhou, Yibin port group as materials distributed in the upper reaches of the Yangtze River important nodes will play a powerful shipping hub and port, forming new engine of economic growth in Western China. From the data of Chongqing — Luzhou — Yibin port group cargo throughput, this paper aims to predict...
This paper reports an efficient and accurate simulation method for vibrations and deformations of single- and multi-layer graphene membranes. In this method, a graphene membrane is modelled by a 2-D plate element whose thickness is changeable in COMSOL Multiphysics. The graphene is regarded as a linear isotropic elastic material, and the load-deformation behaviour is approximated as a doubly clamped...
For the on-line measurement of the fabric color in the batch dyeing process, a novel method is proposed based on soft-sensor. In this method, the concentrations of the dyestuff in a jet dyeing machine are selected as the soft sensor's inputs, and the the fabric color is the output. A nonlinear model, which relates the absorbance with the concentrations of the dyestuff, is obtained based on the experiments...
An efficient hybrid modeling method is presented for analysis of the surface-mount technology (SMT) decoupling capacitor placement in the power distribution network (PDN) of an electronic package. The PDN includes the multilayered power-ground (P-G) planes, the P-G vias, and the decoupling capacitors to provide a low-impedance path between the printed circuit board and the die. The SMT decoupling...
This paper presents a two-dimensional full-wave method for efficient analysis of power integrity and electromagnetic interference (EMI) of high-speed electronic packages. The power/ground planes in electronic packages form a multilayered parallel-plate structure due to the practice of using whole metal plate as power or ground planes. Each pair of power/ground plane is suitable to be modeled by a...
