The Development Trend

The development trend of foreign education is affected by many factors, so its future development trend is difficult to judge. Therefore, it is necessary to simulate and analyze the development trend of foreign education through artificial intelligence. According to actual needs, based on artificial intelligence algorithms, this paper builds artificial intelligence simulation analysis model to realize the simulation analysis of foreign education development. Moreover, starting from the overall design architecture of the online education platform, this paper builds functional modules, uses the machine learning constructed in this paper for data training and data prediction, and outputs prediction results. In order to study the performance reliability of the model, we predict and judge the development trend of foreign education and determine the model reliability through empirical judgment. The research results show that the model constructed in this paper has a certain effect.

The Development Trend

In the global fight against COVID-19 in 2020, tremendous changes have taken place in people's living habits and health awareness. Disinfection has been considered as a significant sanitary step in people's routine life and public places. In this thesis, the characteristics and current status of consumer-grade disinfectant and sterilizing products will be expounded, and the development trend of consumer-grade disinfectant and sterilizing products will be explored from three levels of user experience. Disinfectant and sterilizing products are classified into chemical agents and hardware for disinfection and sterilization. With reference to emotional design theory, this thesis chiefly elaborates the hardware part. By building an analysis model of emotional design and exploring cutting-edge design cases, it is drawn that consumer-grade disinfectant and sterilizing products boast diversified, intelligent, home-based and emotional trends, which is of enormous significance to enhance the systematic design theory and methods of consumer-grade disinfectant and sterilizing products.

The Development Trend

To study the wake development characteristics of wind farms in complex terrains, two different types of Light Detection and Ranging (LiDAR) were used to conduct the field measurements in a mountain wind farm in Hebei Province, China. Under two different incoming wake conditions, the influence of wind shear, terrain and incoming wind characteristics on the development trend of wake was analyzed. The results showed that the existence of wind shear effect causes asymmetric distribution of wind speed in the wake region. The relief of the terrain behind the turbine indicated a subsidence of the wake centerline, which had a linear relationship with the topography altitudes. The wake recovery rates were calculated, which comprehensively validated the conclusion that the wake recovery rate is determined by both the incoming wind turbulence intensity in the wake and the magnitude of the wind speed.
