This research explores the relationship between rheological parameters and quality characteristics of passion fruit and establishes a maturity classification model for passion fruit based on its rheological properties. Each sample undergoes a rheological test, texture profile test, puncture test, and physicochemical index test. These tests aim to gather precise mechanical and physiological information on passion fruit. We built a mechanical testing platform and used machine vision to analyse the micro-deformation of fruit. The platform can measure the real-time contact area and load value to obtain accurate stress values during compression. Non-destructive rheological tests were conducted on intact passion fruit to get the elastic modulus during the loading stage. It is highly consistent with the results of traditional Hertz contact theory. Additionally, the stress relaxation parameters were obtained by fitting the five elements Maxwell model during the holding stage. Notably, there are strong correlations between the rheological parameters and most texture parameters or physicochemical indicators, with the highest correlation coefficient reaching 0.703. Therefore, the rheological parameters were utilised as inputs for maturity classification models (GBDT, MLP, and AdaBoost). All models achieved satisfactory classification results. Particularly, the GBDT model demonstrated excellent classification performance and generalisation capability, with Precision, Recall, and F-Score of 80.44%, 80.08%, and 80.26%. The results show that it is feasible to determine the maturity of passion fruit based on non-destructive rheological characteristics.</div></div>","PeriodicalId":9173,"journal":{"name":"Biosystems Engineering","volume":"250 ","pages":"Pages 236-249"},"PeriodicalIF":4.4,"publicationDate":"2025-02-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143152588","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}

Conventional methods primarily rely on taxonomy and laboratory-based instruments, which are time-consuming and require the requisite expertise. Thus, there is an escalating demand for efficient techniques that can quickly identify these precious species. The advent of Hyperspectral Remote Sensing (HRS) with artificial intelligence has significantly increased the scope of HRS techniques by offering rapid and precise plant identification. This study utilised non-imaging HRS handheld sensors to build a spectral repository for 10 important medicinal plant species from diverse locations across Indian Himalayan states, representing varying altitudinal and ecological conditions. The spectral repository encompasses 1237 distinct spectral signatures obtained from the leaves and canopies of the targeted plant species. Subsequently, an identification model has been developed using Random Forest (RF) with several feature selection methods, and it has been revealed that the RF model, coupled with wrapper-based feature selection, is an effective combination for classifying the targeted plant species. The calibration and test datasets accounted for accuracies of 87.87% and 91.39%, respectively, with corresponding kappa coefficients of 0.85 and 0.89. Furthermore, the developed RF model was applied to ‘PRISMA’ satellite data to identify <em>Saussurea costus</em> crops in farmers' croplands, achieving a classification accuracy of 81.31% and a kappa coefficient of 0.76. Therefore, the study highlights the potential of integrating RF, <em>in-situ</em> HRS, and satellite HRS for the non-destructive, precise, and accurate identification of medicinal plants that can significantly contribute to biodiversity conservation and sustainable resource management.</div></div>","PeriodicalId":9173,"journal":{"name":"Biosystems Engineering","volume":"249 ","pages":"Pages 58-70"},"PeriodicalIF":4.4,"publicationDate":"2025-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143149854","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}

Accurately analysing the structural responses of these greenhouses is particularly challenging due to the difficulty in understanding the actual behaviour of connections using steel clamps. This study focuses on evaluating the stiffness and mechanical behaviour of semi-rigid connections using steel clamps in plastic greenhouses. A specialised load-deformation testing apparatus was developed to assess the relationships between force and displacement or moment and rotation for these connections with various deformation modes. The experimental results were used to model stiffness coefficients and ultimate limit loads, providing a detailed understanding of the mechanical properties of these connections. Findings reveal that steel clamps introduce complex structural behaviours that differ significantly from traditional connections, highlighting the need for advanced modelling techniques. This comprehensive analysis offers new insights into the behaviour of semi-rigid connections in greenhouse structures and underscores the importance of detailed empirical studies.

A prototype apple harvesting manipulator was developed, which includes a vacuum three-revolute-degrees-of-freedom end-effector, a three-prismatic-degrees-of-freedom Cartesian system, an RGB-D camera, and system integration. The vision positioning system and controller were designed to realise precise positioning and detachment of the manipulator.

The method of rotation followed by pull proved to be more effective than only pulling for apple detachment. The results indicated that the apple’s equatorial region was the optimal area for suction. Furthermore, the vacuum pressure should be at least −65 kPa to guarantee successful detachment. Experimental results showed that 83.1% of harvested apples had stems intact. For the developed manipulator, a 33<em>ϕ</em> mm diameter suction cup, a rotate-and-pull separation method, and −65 kPa were recommended for practical applications.

Initially, utilising traditional design concepts, the side-plate reinforcing rib was segmented into units and analysed using ANSYS to develop an initial model. Evaluation indices such as specific strength structural efficiency and specific stiffness structural efficiency were employed to perform orthogonal optimisation of the rib dimensions, achieving optimal measurements of 72.9 mm in length, 15.7 mm in width, and 3.5 mm in thickness. These dimensions enhance the specific strength structural efficiency by 14.14% and the specific stiffness structural efficiency by 0.95% compared to the initial model. Further, the rib's mathematical model was refined and generalised by a curve-fitting method across different rotary blade models (IT series), followed by topological optimisation to fine-tune morphological features. This optimisation reduced the model's mass by 9.78% and improved efficiency metrics by 2.6% (strength) and 0.5% (stiffness). Comparative experiments using DEM-FEM coupled analysis were conducted on three optimised models to assess the redesigned blade's performance. The experiments evaluated key performance metrics such as neck force, maximum stress, fatigue life, and ultimate fracture stress. The results indicate that after two rounds of optimisation, the blade's neck force was reduced by 16.85%, the maximum stress decreased by 15.22%, the fatigue life increased by 76.03%, and the ultimate fracture stress improved by 20.16%. These changes align with the optimisation objectives.

To address this issue, a novel method is developed to delineate paths for weeding tools, thereby preventing harm to seedlings. This method employs an advanced version of YOLOv8Pose to detect weeding areas around maize seedlings by pinpointing key points on the maize seedlings. To enhance the detection accuracy, a multi-scale dilation attention (MSDA) module and a lightweight reparameterisable EfficientRep module were used. The root connection line of the maize row was obtained by sequentially connecting the key point positions. The guide line for the weeding component was then determined by correcting this root connection line using the median absolute deviation (MAD) as the threshold. The approach demonstrated a remarkable precision in guiding weeding lines with an angular error of only 0–3° and a recognition rate of 100 FPS. In actual weeding operations, the effective weeding rate was 95.6%, which was far better than the 74.2% obtained by the leaf recognition-based method.
