Based on the distribution of straw in the field, this study explored the effect of the amount of surface straw cover on the pressure subsidence relationship in Shajiang black soil. The quadratic rotated orthogonal combination test was used to quantify the mathematical relationships of Shajiang black soil pressure subsidence modeling with the amount of surface straw cover (SSC) and mass mixing ratio of soil to straw (MSS). Then, using the weighted least squares method, the pressure subsidence parameters (cohesive deformation modulus, friction deformation modulus, and subsidence index) were obtained, and the Bekker model was modified to construct a pressure subsidence model for the straw-containing soil. Finally, the modified model was verified under conditions of a water content of 18 %, the SSC of 2.5 t·ha⁻¹, and the MSS of 2.5 %. Results showed that the proposed pressure subsidence model predicted the value with a relative error of 2.21 % compared with the experimental measurements. The model’s predicted value accuracy improved by 10.65 % compared to the conventional model. From these results, this study proposes that a mixed crop straw Shajiang black soil pressure subsidence model can predict the soil’s internal stress transfer and stress–strain conditions.</div></div>","PeriodicalId":50627,"journal":{"name":"Computers and Electronics in Agriculture","volume":"227 ","pages":"Article 109649"},"PeriodicalIF":7.7,"publicationDate":"2024-11-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142661677","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

First, the constrained canopy structure dynamic hierarchical linear model (CSDHLM) is constructed, which integrates canopy dynamics information and temporal constraints. Second, the microwave scattering characteristics at various crop growth stages used to develop the phenological segment dynamic time warping (PSDTW). The PSDTW aims to address the challenges posed by inconsistent phenological dynamics across different plots.

This framework incorporates three key features contributing to its effectiveness. Firstly, Sentinel-2 reflectance was generated using the PROSAIL model and refined through sample matching to ensure optimal alignment with Sentinel-2 imagery specific to each crop type.

The implementation details are as follows: Firstly, the data collected by the six-axis inertial sensor is preprocessed using a sliding window to obtain time series data, and perform Fourier transform on it to obtain the frequency domain sequence. Then, the transformer is used to unify the time domain and frequency domain features respectively. A Mutual Promotion Unit (MPU) is established based on cross self-attention and a feedforward neural network (FFN). By integrating with a Global multimodal fusion (G) module, MPU establishes a global–local interactive learning framework to extract features from temporal and frequency domains, resulting in temporal-frequency interaction features. Finally, the introduction of supervised contrastive loss function supervises the training process, enhancing the accuracy of fish school feeding intensity classification.

Therefore, we proposed a semantic segmentation network called Broccoli Segmentation (BroSeg) for the mature identification and localisation of broccoli.

In the absence of dedicated swine behavior monitoring systems and the challenges of implementing cloud-based automated monitoring in large-scale farming, this study proposes a method utilizing inspection robots to detect behaviors of lactating sows and piglets. The inspection robot initially serves as a data acquisition and storage tool, collecting behavioral data such as sows postures (standing, sitting, lateral recumbency, and sternal recumbency) and activities of piglet groups (resting, suckling, and active behavior) within confined pens. The YOLOv8 series algorithms are then employed to identify static postures of sows, while the Temporal Shift Module (TSM) is used to recognize dynamic behaviors within piglet groups. These models are fine-tuned and deployed on the Jetson Nano edge computing platform. Experimental results show that YOLOv8n accurately identifies sow postures with a mean Average Precision (mAP) @0.5 of 97.08% and a frame rate of 36.4 FPS at an image resolution of 480 × 288, following TensorRT acceleration. For piglet behavior recognition, the TSM model, using ResNet50 as the backbone network, achieves a Top-1 accuracy of 93.63% in recognizing piglet behaviors. Replacing ResNet50 with MobileNetv2 slightly reduces the Top-1 accuracy to 90.81%; however, there is a significant improvement in inference speed on Jetson Nano for a single video clip with a processing duration of 542.51 ms, representing more than a 20-fold enhancement compared to TSM_ResNet50.

The multi-scale biological signals were collected using the respiratory sensor and the multi-dimensional posture sensor (composed of an accelerometers, gyroscope, and magnetometer), and then, after data processing, extracted signal features and used the dimensionality reduction method of principal component analysis (PCA).

Each of these behaviors exhibits unique characteristics in their signal images. (2) PCA was utilized to reduce the dimensionality of the feature fused dataset of the multi-scale biological signals, preserving principal components with a cumulative contribution rate of 98 %.

The study of the possibilities and limits of these networks is an active area of research. In this paper we describe a LoRa-based multi-hop WUSN for monitoring soil moisture for an application in agriculture being developed to investigate the behaviour of different species of <em>mamona</em> (<em>Ricinus communis L.</em>) under different soil moisture levels. We first evaluate the use of LoRa for underground-to-underground (UG2UG) communication links and show how different values of the main LoRa parameters affect the quality of these links. Based on the results, we designed a network whose topology is a set of lines of buried sensor nodes covering the whole application area. In this paper we describe the behaviour of one of these lines in a real setting in terms of packet delivery ratio and delay and we estimate the energy consumed for communication. Our protocol provides an inherent level of fault-tolerance by exploring the linear topology. In our experiments, a 100% message delivery ratio was achieved. Additionally, the maximum round-trip delay was less than 200 s. The network satisfies the application message transmission requirement of one message per hour per node by scheduling communication over the six sensor lines needed to cover the whole experiment area in a round-robin fashion.
