With the advancement of industrial automation, the quality requirements for automotive engine assembly bolt tightening have become increasingly stringent, as they are directly related to engine performance and vehicle safety. Traditional monitoring methods for bolt tightening rely on preset torque criteria, which often overlook anomalies such as material defects and tool wear. To address the issue of limited negative samples in industrial data, this study proposes an innovative positive sample boundary modelling strategy based on artificial intelligence, combined with a random forest algorithm for anomaly detection. By transforming time-series data into high-dimensional feature data, an efficient classifier is constructed through the integration of multiple decision trees. Experimental results from real engine assembly line data demonstrate that the proposed method can quickly and accurately identify abnormal conditions without increasing computational burden, significantly improving assembly quality and reducing failure rates.

Sequence-to-graph alignment is a critical component of pan-genome-based read alignment and represents the most computationally intensive step in this process. To address this challenge, we have introduced a sequence-to-graph alignment algorithm based on graph folding, which minimizes the size of the graph structure and enhances alignment efficiency while identifying the optimal path. Experiments on both simulated and real datasets demonstrate that our algorithm significantly improves the speed of sequence-to-graph alignment. The source code is available at Github: https://***/zzzerd/fgpoa

Due to the influence of objective factors such as scene noise and hardware equipment, compared to CAD modeling point clouds, the real point clouds collected by LiDAR often have strong non-uniformity and irregularity, which leads to the low ability of traditional point cloud classification models to extract point cloud features in real scenes and poor classification robustness. To address this issue, we have added a local feature fusion module and a dense connected feature fusion method to PointMLP, thereby encoding broader point cloud information into local features. The simple stacking of multiple MLP and Mixer blocks constitutes our network model-PointMM. The shallow features of the point cloud are used as input and enter the local feature fusion module to perform feature fusion within and between point sets. Finally, by maximizing the pooling layer and selecting points with stronger semantic features as inputs to the second stage feature extraction module. This method has been tested on the ScanObjectNN dataset and shows that it can approach SOTA with a classification accuracy of 0.8%, surpassing other mainstream models.
