CONDITIONS FOR SAFETY OPERATION AND MANEUVERABILITY OF LOW-TONNAGE ROADTRAIN AT CRITICAL RATES OF MOTION

The paper deals with the control device for a uniaxial trailer, which makes it possible to increase the maneuverability and reliability of the movement of a low-tonnage roadtrain by using flexible coupling in the hitch mechanism.This makes it possible to use roadtrain at emergency situations, in narrow urban streets, in greenhouses, livestock house

In stock trend forecasting system, feature selection and model building are two major factors that affect prediction performance.In order to improve the accuracy of prediction and the stability of the model, a stock trend prediction model of Fractal-FOA-LSTM is proposed.Firstly, the features are selected by using the FOA (fruit fly algorithm) combi
