A factorial and Box–Behnken design varied vibration direction, operating speed, frequency, and amplitude; response-surface models were fitted for the qualified index, multiple index, and leakage index. Vertical vibration exerted the dominant influence on discharge behaviour. Under weak excitation (frequency<15.38Hz; amplitude<3.42mm), increasing vibration intensity reduced multiple seeding and improved the qualified index, whereas stronger excitation (frequency>15.38Hz; amplitude>3.42mm) increased leakage and reduced the qualified index, delineating a usable–detrimental vibration regime boundary.

Lodging in rice not only reduces the efficiency of mechanical harvesting but also severely impacts yield and grain quality. Therefore, accurately identifying lodged areas is of great importance. This study proposes a rice lodging detection method based on UAV-acquired multispectral remote sensing imagery. High-resolution, multi-temporal images were collected over paddy fields in Yuhang District, Zhejiang Province, using DJI Mavic 3 M and M300 UAVs. A dataset was constructed via image cropping and data augmentation. Two deep learning models—U-Net with a VGG-16 backbone and DeepLabv3+ with a MobileNetv2 backbone—were compared for semantic segmentation performance. Experimental results show that the U-Net model achieved superior performance on the validation set, with a mean Intersection over Union (MIoU) of 91.57 %, mean Pixel Accuracy (MPA) of 95.83 %, Precision of 95.27 %, Recall of 95.83 %, and training/validation losses of 0.106 and 0.151, respectively, outperforming the DeepLabv3+ model. Additionally, the impact of different training-validation data split ratios was examined. The U-Net model showed better generalization and stability when trained with a 9:1 split compared to an 8:2 split. Furthermore, based on the semantic segmentation results, the area of lodged rice was estimated and compared against ground-truth measurements. The U-Net model produced minimal relative error, with a maximum deviation of <3 %, demonstrating strong practical applicability.

Nevertheless, monitoring such behaviors remains challenging owing to intricate aquatic environments, frequent occlusions, and considerable visual similarities across different behavioral categories. To tackle these issues, this study introduces an Efficient Parallel Attention Fusion Detection Transformer, designated as EPAF-DETR, which is developed to achieve high-precision and robust object detection. By integrating EfficientViT as the backbone network, the computational complexity of the model is significantly reduced. Combined with an adaptive sparse self-attention mechanism and a spatially enhanced feedforward network, an improved AIFI module is introduced to strengthen feature extraction capabilities. Furthermore, Multi-Level Hierarchical Attention Fusion module is designed to enhance the original cross-scale feature fusion component in RT-DETR, enhancing the salience of critical features and further improving detection accuracy. Finally, by incorporating Matchability-Aware Loss function, the model is guided to place greater emphasis on matching low-quality features.These architectural advancements considerably boost the model’s adaptability in demanding underwater settings and augment its capacity to discriminate fine-grained behavioral characteristics of fish.

While Intelligent Irrigation System (IIS) units can effectively reduce labor input, their benefits are influenced by the location of the installations. Consequently, determining optimal field combinations under varying installation conditions (varying numbers of IIS units and farmer datasets) has become a critical issue. This study proposes and validates a two-stage optimization framework for IIS unit installation that employs patrol-route distance reduction as the evaluation metric. In the first stage, Density-based Spatial Clustering of Applications with Noise (DBSCAN) with the Normalized Nearest-distance (NN-distance) method was applied to mitigate search space explosion under non-uniform densities. In the second stage, the 2-opt algorithm was used to optimize patrol routes and quantify labor reduction. Validation results showed that the framework compressed the candidate solution space and alleviated the computational complexity associated with the Non-deterministic Polynomial-time hard (NP-hard) nature of the problem. Furthermore, the NN-distance method maintained solution quality and outperformed the conventional k-distance approach by mitigating over-clustering and over-segmentation under non-uniform spatial distributions. Case analyses revealed that the benefits of IIS unit installation depend not only on the number of installed units but also strongly on the spatial distribution of fields.
