In order to meet the requirements of traffic data fusion for real-time urban traffic state estimation, a new kind of fusion structure model is proposed. This fusion model consists of both spatial fusion and temporal fusion. First we use the power average operator as spatial fusion method. Then we propose a temporal correlation based data compression (TCDC) algorithm, based on segment linear regression...
Mine ventilation resistance is decided to coefficient of frictional resistance. and it is very vital to airflow distribution of using air place, With the special conditions of roadways of I-beam supporting in the article, the coefficient of frictional resistance is calculated through an improved BP artificial neural network model, and the article analyses the difference between BP neural network calculation...
In order to develop low energy consumption and high efficiency stirrer, authors have designed a new type of cylinder stirrer for low viscosity medium. In this article, CFD investigation of the flow field, power consumption and mixing time in lab-scale vessels by large height diameter ratio cylinder stirrer are performed. Three-dimensional time-dependent flow and mixing prediction have been carried...
