New energy vehicles provide new solutions for low-carbon emissions. With the continuous expansion of the new energy vehicle industry, a more scientific supply chain management system is needed to effectively identify and evaluate risks. This study proposes a more scientific and comprehensive risk assessment method for the supply chain system of new energy vehicles based on a hierarchical holographic model and matter element extension model. The results showed that the proposed algorithm improved the classification performance of risk factors by 1.2%, 1.3%, and 1.5% compared to the clustering performance of the nearest frequency amount clustering, particle swarm optimization, and self-organizing mapping algorithms. In terms of noise processing effectiveness, the Rand index has improved by an average of 55% and 41% compared to the kernel density threshold algorithm and spectral clustering algorithm, with smaller fluctuations and significant differences (P © 2025 Slovene Society Informatika.

Asphalt pavement will inevitably produce internal distresses during service, which increases the risk of deterioration of pavement structural performance. Although threedimensional ground penetrating radar (3D GPR) with a multi-channel antenna array can detect the internal structural condition of asphalt pavement non-destructively and quickly, there is currently a lack of effective evaluation index and standard. In this paper, 3D GPR was used to investigate four typical internal distresses of existing asphalt pavement in GuangzhouShaoguan Expressway, including cracks, loose, cavities, and poor interlayer bonding. In particular, GprMax software was used to establish the quantitative relationship between base crack width and radar images. Based on the radar image characteristics of different internal distresses, the distresses at the asphalt layer, base, and subbase were identified and statistically analysed. Pavement internal condition index (PICI) was proposed to quantitatively assess the internal distress condition of asphalt pavement. The results show that the PICI based on 3D GPR is reliable for evaluating the internal distress condition of pavement structure, and can be used as an important supplementary part of pavement structural integrity evaluation. The evaluation results can provide a reference for asphalt pavement maintenance decision. © 2025 The Author(s).

An improved genetic algorithm is proposed for the path planning of a bulk solids clearance robot using a terrain traversability raster map. The traversability raster map is established by a fuzzy logic inference method based on the environmental terrain characteristics and robot traversability. A new fitness function involving the path length, smoothness and the traversability cost, is also developed. Logistic chaos mapping is used for initializing the population to enhance the randomness of the initial population distribution, and a catastrophic population update mechanism is introduced to improve the genetic algorithm. The simulation results show that the paths planned based on the improved genetic algorithm have higher quality and faster convergence compared to the original algorithm. © Beijing Paike Culture Commu.

Lane-changing behavior significantly affects traffic safety, often leading to severe casualties and substantial property damage. A lane-changing safety warning model can help drivers make safer lane-changing decisions, thereby reducing accidents. This study is based on the US-101 segment of the NGSIM dataset, where sample data of lane-changing passenger vehicles were selected following specific filtering criteria. A set of driving style indicators related to driving safety was chosen. Factor analysis was employed to reduce the dimensionality of the selected indicators, and the k-means clustering method was then used to classify driving styles into two categories: conservative and aggressive. The results show that aggressive drivers exhibit greater speed fluctuations compared to conservative drivers. Therefore, in the development of a lane-changing safety warning model based on Time to Collision (TTC), an additional minimum safe distance was introduced as a secondary warning criterion for aggressive drivers, aiming to reduce false warnings caused by sudden speed changes. Validation results indicated that the model achieved an accuracy of 82.7%, demonstrating its effectiveness. This warning model provides a foundation for further research into the safety of lane-changing behavior on highways and the reduction of lane-changing accidents. © Beijing Paike Culture Commu.

In order to obtain the optimal PVDF piezoelectric fiber film to enhance its piezoelectric properties, PVDF was used as solute, N–N dimethylformamide (DMF) and acetone were used as solvents, and the electrospinning process parameters and electrode corona were optimized. Based on the control variable method, the effects of solvent ratio (volume ratio of DMF to acetone), solution concentration, spinning voltage, solution injection speed and receiving drum speed on the performance of PVDF piezoelectric fiber membrane were studied and analyzed. The characterization results of the viscosity of PVDF solution, the microstructure of PVDF piezoelectric fiber membrane, the content of crystal phase, the piezoelectric constant, the tensile strength and the dielectric constant after silver electrode were measured. The optimal preparation process parameters of PVDF piezoelectric membrane were obtained: solvent ratio 6:4, solution concentration 15%, spinning voltage 21.5 kV, solution injection speed 0.04 mm/min and receiving drum speed 1800 rpm. © The Author(s), under exclusive license to Springer Nature Singapore Pte Ltd. 2025.
