Abstract.Based on the intercalating melt-blown non-woven material performance control principle, through the single factor analysis of variance, two-factor variance analysis and typical correlation analysis, partial least-squares regression model is established, a multi-objective optimization model, structure parameters and performance parameters of the respectively as sample, using the typical correlation analysis between the two sample data, the paper analyses the inner link, The results show that product thickness has a strong positive correlation with filtration resistance.Then the Pearson … Read more →

Abstract.In order to reduce the risk of fire extinguishing and protect the safety of people's lives and property. Design a trolley with fire warning, autonomous patrol, autonomous obstacle avoidance, and automatic fire extinguishing. The car can replace patrol personnel, carry out uninterrupted patrols in fire-prone situations, and alarm when dangerous gases or smoke are generated. When the robot detects a fire, it immediately performs intelligent fire extinguishing. The fire extinguishing robot of this paper mainly involves the application of STM32 single-chip microcomputer and multi-sensor, the … Read more →

Abstract.At present, due to the unreasonable allocation of resources in waterway transportation, problems such as emissions amplification and serious pollution are caused. This paper considers the impact of carbon tax and SECA on the speed of navigation, and considers the operating costs such as inventory cost, fuel replenishment cost, carbon tax, ship time delay cost, etc., to minimize the total operating costs with the limitation of time window.
