Based on the Internet of Things technology, this paper proposes building a cross-border e-commerce logistics supervision system and determines the evaluation index system from the overall framework design of the system, supply chain supervision process optimization, risk supervision optimization, and system order degree optimization.First of COLOR

Maximum entropy is a powerful concept that entails a sharp separation between relevant and irrelevant variables.It is typically invoked in inference, once an assumption is Containment Systems made on what the relevant variables are, in order to estimate a model from data, that affords predictions on all other (dependent) variables.Conversely, maxim

General method which often used in measuring lateral vibration in the ship is vibration-meter.This method has some limitation like complicated, high cost, just can measure vibration at house of bearing and cannot measure vibration at shaft which rotated.Other limitation is the optimum censor at high rotation up to 600 rpm.Based on the above conditi
