In recent years, the rapid development of deep neural networks and their application technologies has propelled autonomous driving systems (ADS) towards commercialisation. However, due to the high safety requirements of ADSs, ensuring their safety and reliability remains a critical challenge in software engineering. Existing testing methods focus on simple driving scenarios with few traffic participants, neglecting the impact of high traffic density on ADS driving performance. This paper presents an empirical study exploring how traffic density affects ADS behaviour. We developed a testing framework using two open-source ADSs to generate scenarios with varying traffic densities in a high-fidelity simulator. Our results indicate that changes in traffic density significantly affect ADS performance. Different traffic densities reveal various types of safety violations and help identify potential design flaws in ADSs. This study highlights the importance of considering traffic density in ADS testing and contributes to a better understanding of ADS performance under different traffic conditions.

Using the applied software developed on the basis of the computer algebra system "Mathematica" and its functions of symbolic-numerical modeling, the dynamics of the rotational motion along the circular orbit of a satellite-gyrostat in a Newtonian central field of forces is investigated. In accordance with the problem of Lyapunov's stability from the equations of perturbed motion in the first approximation, the regions with an even degree of instability by Poincare are found in the space of introduced parameters. The paper considers the question of the possibility of gyroscopic stabilization of unstable relative equilibrium positions of the gyrostat, when the vector of the gyrostatic moment of the system is located in one of the planes formed by the principal central axes of inertia. The research results were obtained in a symbolic (analytic) form on a computer and by means of a numerical experiment with the graphic interpretation.

The concept of smart city development originated from the idea of 'Smart Earth' proposed by IBM in 2008. The Chinese government has been actively promoting the planning and construction of smart cities to address challenges such as traffic congestion, medical issues, and environmental pollution caused by rapid urbanization, with the aim of improving public welfare. Currently, countries worldwide are embracing the construction of smart cities, utilizing information and communication technologies like big data and cloud computing to achieve efficient management of cities in terms of public services, governance, and livability, thus promoting sustainable urban development and enhancing residents' convenience. As China's urbanization progresses and information technology advances, along with people's pursuit of a high-quality life, new concepts and requirements for smart cities have emerged, necessitating the timely development of new smart city concepts. The public, being the end users and evaluators of smart city construction outcomes, holds significant influence in assessing the quality of such construction. However, previous studies on smart cities have predominantly focused on technological advancements, neglecting the evaluation of smart city construction effectiveness from the perspective of citizens. Therefore, establishing a scientific and reasonable performance evaluation index system for new smart city construction is crucial to the construction of new smart cities, based on the public's direct experience and user perception. This study introduces user perception as a key component in the evaluation system for new smart city construction and established a new smart city construction performance evaluation index system based on user perception. By doing so, it aims to provide a more comprehensive understanding of the actual impact of urban development on residents' lives. To establish the evaluation index system, the study combines research findings from relev

The traditional control method of wheeled robot has the problem that system is unstable due to the inconsistency between the actual state and the target state. Therefore, this paper proposes a double closed-loop control strategy based on trajectory tracking considering global stability. Initially, a comprehensive kinematics model is formulated. Based on the kinematics model of the system, the controller is designed to ensure the Lipchitz condition of position tracking closed-loop system, so as to ensure that stability of the system. Subsequently, the stability of the controller is validated through the application of Lyapunov stability theory. Finally, the effectiveness of the control strategy is verified by simulations.
