The feeding behaviour of cows is an essential sign their health in dairy farming. For the impression cow status, precise and quick assessment critical. This research presents a method for monitoring utilizing edge computing deep learning algorithms based on characteristics behaviour. Images were captured processed real time using device. A DenseResNet-You Only Look Once (DRN-YOLO) was presented to address difficulties existing detection algorithms' low accuracy sensitivity open farm...
The behaviors of dairy cows, such as feeding, ruminating, running, resting (standing, lying), head-shaking, drinking, and walking, can indicate their health status. In this study, a multi-sensor was used to collect data cow's multi-behaviors for research on behavior recognition. Firstly, collar style acquisition system equipped with geomagnetic acceleration sensors the behavioral cows during daily activities designed. Secondly, cow recognition fusion model based K-Nearest-Neighbors (KNN)...
The classification of silkworm cocoons is essential prior to silk reeling and serves as a key step in improving the quality raw silk. At present, cocoon mainly relies on manual sorting, which labor-intensive inefficient. In this paper, detection algorithm S-YOLOv8_c based cooperation MobileSAM YOLOv8 for mountage was proposed. with designed area thresholding used semantic segmentation images, could mitigate effect complex backgrounds maximize discriminability features. Subsequently, BiFPN...
The working environment of agricultural knives is bad, which makes the wear out easily. A resistant layer AlCoCrFeNi high entropy alloy (HEA) reinforced by tungsten carbide (WC) was prepared laser cladding on one side cutting edge a 65 Mn silage knife. Both effects WC addition microstructure and mechanical properties (WC)x (x = 0, 0.1, 0.2 0.3 in mass percentage) alloys were investigated. All experimental displayed crystalline structure simple body centered cubic (BCC). hardness increases...
Abstract In this study, the effects of electrolyzed oxidizing water (EOW) on prevention enzymatic browning fresh‐cut “Jiu Jinhuang” Chinese yam were investigated. The yams immersed in inhibitors for 25 min at 20 °C. Compared with tap (TW) treatment, chromatic attributes significantly different after 72 h storage ( P < 0.05). activities polyphenol oxidase (PPO, EC 1.10.3.1), peroxidase (POD, 1.11.1.7), and L ‐phenylalanine ammonia lyase (PAL, 4.3.1.5) inhibited when measured 24 h. contents...
Existing push robots mainly use magnetic induction technology. These devices are susceptible to external electromagnetic interference and have a low degree of intelligence. To make up for the insufficiency existing material pushing robots, at same time solve problems labor-intensive, inability in night, etc., this study, an autonomous navigation pusher robot based on 3D lidar is designed, obstacle avoidance strategy improved artificial potential field method proposed. Firstly, point cloud...
Abstract Drying of okara cake was investigated in an oven at 105°C with or without the electrohydrodynamic (EHD) technique. The cakes (77 g weight and 81.57% ± 0.14%wb initial moisture) were put Petri dishes 93 mm internal diameter 18 depth. One sample exposed to a high electric field (HEF) established needle plate electrodes other treated as control. During drying, voltage applied −20 0.1 kV, number point 1 3, electrode gap 35, 50, 65 mm. Varying needles HEF drying rate found be 1.7–3.2...
To verify the effect of ohmic heating on urease activity in soymilk, methods with different electrical field conditions (the frequency and voltage ranging from 50 to 10 kHz 160 220 V, respectively) were employed. The results showed that if value measured quantitative spectrophotometry method was lower than 16.8 IU, qualitative negative. sample ohmically heated significantly conventionally (P < 0.01) at same target temperature. It concluded enhanced inactivation. In addition, inactivation...
The harvesting straw feed crops (silage corn, alfalfa, herbaceous mulberry, etc.) was tedious, high-labor-cost, and large-nutrient-loss. A self-propelled forage crop harvester, which could realize the integration of cutting, flattening modulating, chopping, throwing crops, designed. cutting angle freely be adjusted between 0° 8°. max rotation speed roller reach 590 r/min consecutively by hydraulic control device. To verify performance this machine, several experiments silage mulberry with...
To investigate the effects of corona discharge field treatment different electric strength with polarities on vigor millet seeds, positive and negative fields generated arc-shaped prick electrodes plate are for seeds respectively. The voltage was (2 × n kV, = 1, 2. . .10) time treated 2 min. results showed that after by field, germination potential, rate, index increased to degrees compared control. optimal voltages were 12 kV. Under voltage, indexes (germination index, index) significantly...
The working environment of agricultural cutting tools is poor, and the operational quality efficiency are reduced after they become blunt. This study aimed to develop a high wear-resistant agriculture knife with long life. A Ni–WC alloy, layer was prepared using laser cladding technology on one side edge 65 Mn silage knife. self-grinding formed when cladded used, which improved service life microstructure, phase, composition, hardness distribution were detected analyzed. impact toughness...
Simulation analysis and parameter optimization are performed for the loading mixing devices of a self-propelled total mixed ration mixer.

Dielectric properties (dielectric constant and loss factor) of Australia lignite were determined using an impedance analyzer other instruments over the moisture contents 8–48%, temperature 25–100°C, frequency 1–50 MHz. Both dielectric factor samples increased monotonically with increase content at all temperatures frequencies. frequency, changed quadratically: first decreased then increased. low (8–28%), but it high (38–48%), contents. The penetration depth radio energy was obtained through...
When seeds are treated with a high-voltage electric field (HVEF) to improve seed vigor, due the large differences in biological electromagnetic effects on different types of seeds, methods variance analysis and regression based data statistics generally used construct optimal dose prediction model; however, generalization performance model tends be poor.
