Nonlinear Control and Synchronization with Time Delays of Multiagent Robotic Systems by Yassine Bouteraa, Jawhar Ghommam, Nabil Derbel, Gérard Poisson

“…The developed control combines trajectory tracking and coordination algorithms. To address the time-delay problem in the cooperative network communication, the suggested synchronization control law is shown to synchronize multiple robots as well as to track given trajectory, taking into account the presence of the time delay. …”

A Fixed-Time Hierarchical Formation Control Strategy for Multiquadrotors by Miaojie Huang, Qiang Lu

“…This paper deals with the problem of multiquadrotor collaborative control by developing and analyzing a new type of fixed-time formation control algorithm. The control strategy proposes a hierarchical control framework, which consists of two layers: a coordinating control layer and a tracking control layer. …”

On a Perturbed Risk Model with Time-Dependent Claim Sizes by Longfei Wei, Jia Hao, Shiyu Song, Zhenhua Bao

“…We consider a risk model perturbed by a Brownian motion, where the individual claim sizes are dependent on the inter-claim times. We study the Gerber–Shiu functions when ruin is due to a claim or the jump-diffusion process. …”

On Time Effect of Preschool Education: Social Analysis Based on CUCDS by Bohan Yan, Yongjun Feng, Ning Cai

“…It is discovered that the impact of preschool education on children’s cognitive development differs depending on the cognitive ability and the length of time. In particular, preschool education has both short-term and long-term effects on children’s Chinese cognitive ability, while there is only a short-term effect on the development of children’s mathematical cognitive ability without long-term effect.…”

Application of Neural Networks in Financial Time Series Forecasting Models by Xinhui Li

“…As an algorithm model that can simulate the biological visual system, the convolutional neural network can predict the numerical trend of the next period of time based on known data. Therefore, this paper integrates the support vector machine with the established model by establishing a convolutional neural network model and applies the prediction model to the prediction of financial time series data. …”
