Abstract. This paper aims to explore a vehicle stability control strategy based on sliding mode variable structure control theory. The smart car is used as the simulation object, and the vehicle's centroid angle and control system are mathematically modeled and controlled. The research was carried out and joint simulations were carried out with three typical working conditions: icy road surface, wet asphalt road surface and dry concrete. The simulation results show that the designed control algorithm can significantly improve the lateral stability of the vehicle, so that the vehicle has strong adaptability to the road surface and different driving speed under different working conditions, thus improving the braking of the car as a whole. Performance, drive performance and steering performance.

Auspicious cloud is one of the most Chinese-style auspicious patterns with a long history in China. However, most of previous research works focus on realistic cloud animation, little effort has been paid to model auspicious cloud in traditional Chinese style. In this paper a procedural modelling method is presented. First, we construct the cloud skeleton curve by use of eclipses, we then arrange a series of primitive circles with different radiuses along with points in the curve and obtain cloud silhouette by union of these circles; We take a dynamic silhouette point as start position and draw a spiral curve along the centre of cloud. Experimental results show that the proposed method is able to generate a wide variety of auspicious clouds in traditional Chinese style.

Kitsak et al argued that nodes dwell in diverse network shells by a k-core decomposition process show more reliable identification for nodal importance which had attracted more and more attentions in different domains. But one seldom focuses on the distribution of node numbers (DNN) in different shells of a network, experiment results show regular characteristics. While, the existing theoretical network models, such as BA scale-free model, WS Small-world model, ER random network model et al cannot reproduce the features. To fill this gap, a group of coreness tunable network (CTN) models are proposed, in which the coreness of each node is totally controllable. The CTN has a similar network performance compared to real-world by counting basic static geometric features and spreading performance under SIR model. Our CTN models are providing a theoretical framework to deepen humans’ understanding of the coreness structure and function of complex networks.

Abstract. In order to solve the problem of system interference caused by noise interference of laser communication system, according to the theory of finite aperture receiving intensity fluctuation, the signal-to-noise ratio model based on the influence of atmospheric fluctuation on atmospheric turbulence and no turbulence is established respectively, and the BER model of laser communication system under turbulent conditions is given. Through calculation and analysis, the intensity fluctuation and the receiver aperture at the receiving end are the main factors causing the fluctuation of the performance of the atmospheric turbulent optical communication system. The model can effectively evaluate the BER performance of laser communication systems under atmospheric turbulence conditions and provide reference for relevant theoretical research.

In order to solve the tracking failure of kernelized correlation filter (KCF) tracking algorithm in the case of target fast motion and motion blur, proposing a multi-sampling tracking algorithm based on KCF. Firstly, a PSNR-based judgment mechanism is introduced to determine whether the current frame target is tracking errors. If the tracking error occurs, the search range is extended to a mutisampling search area. Finally re-detect the target of the current frame. The improved algorithm of this paper is compared with several classical correlation filter target tracking algorithms in the OTB video dataset. The experimental results show that the precision of this algorithm is 0.732 and the success rate is 0.575, ranking first, which is 5.3% and 4.3% higher than the KCF algorithm. Especially when the target has fast motion and motion blur, it has stronger tracking accuracy.
