Under fatigue load, insulated gate bipolar transistor (IGBT) experience structural damage and performance degradation, imparting the reliability of power electronic systems. To address this, the relationship between solder layer fatigue crack length and thermal resistance is derived based on heat transfer theory, firstly. The Darveaux model is used to characterize the evolution law of solder layer cracks in IGBT, and a new IGBT performance degradation model along with a method for estimating its undetermined coefficients is proposed. Then, considering the non-stationary characteristics of actual working conditions, a variable amplitude fatigue load model for IGBT is established using the response surface methodology. The rain flow counting method and linear cumulative damage citation are then employed to assess the extent of IGBT performance degradation. Finally, using a type of IGBT product as an example, power cycling thesis are conducted, and performance degradation modeling and analysis are carried out based on experimental data, verifying the effectiveness of the models and algorithms.

Automatic and accurate collection of fishery catch data is an important part of the electronic observer system. However, automated tuna longline catch estimation remains challenging to deploy in practice due to the complexity of the working environment and the instability of tracking. In this study, a lightweight counting network was designed to automate the processing of real-time video data from fishing vessels in order to enable real-time tracking and counting of tuna catches on board fishing vessels. YOLOv5s was selected as the benchmark network in this study. The channel pruning algorithm was first used to prune the backbone network of YOLOv5s, and the results showed that the detection accuracy of the pruned model mAP0.5~0.95 reached 68.8%, and the detection speed was 16.5 frames per second （FPS） under CPU, which was basically unchanged compared with the original model. The number of parameters, model size and computation of the model were reduced by 67.2%, 66.4% and 42.5% respectively, and the detection speed was increased by 33.1%. Secondly, the ByteTrack algorithm was used to achieve real-time tracking of multiple targets, optimize the shape of the counting area and solve the problem of counting deviation caused by the jump in the identity （ID） of the tuna being tracked. The test results of 10 videos showed that the average counting accuracy of the method was 80% and the video processing speed was 50.7 FPS, which meets the requirements of industrial-grade real-time detection. In summary, the model had the advantages of light weight, high accuracy and real-time, which could complete the real-time monitoring of longline catch in complex working environments and provide a solution to realizing fisheries automation.

Several reports have explored the value of electronic identification systems (EISs) in reducing incorrect blood recipient identification. Here, we report a multi-institutional study to clarify the usage and limitation of EISs for pretransfusion sample collection and blood administration. From October 2020 to March 2022, 26 institutions were registered in the study. 15 (58%) used EISs for blood collection, and 25 (96%) for administration. In several institutions, EISs were not implemented in departments in which massive bleeding may occur, such as the emergency department, operating room and angiography room. 12 institutions reported 52 cases of error and near-miss events of wrong blood in tubes and wrong component transfusion. Blood samples were collected from the wrong patient in 17 cases, EISs were not used before blood administration in 8, and the wrong component was transfused to patients in 7. Of 52 errors and near-miss events, EISs were not used properly in 41 (79%). Clinical staff did not understand the use of EISs before blood collection and administration in 9 and forgot electronic patient identification before blood collection or administration in 5, and electronic patient identification was not performed before blood collection or administration due to an emergency situation in 3. Further efforts are needed to improve patient safety in the transfusion process. [ABSTRACT FROM AUTHOR]

Nowadays, the automatic weighing technology of Load Haul Dumper (LHD) was used more and more widely in big mines all over the country, however, the weighing measurement accuracy is still relatively low. The main purpose of this paper is to improve the measurement accuracy of LHD. Based on the weighing mechanics theoretical model, lifting cylinder hydraulic pressure is the core factor of automatic weighing. By analyzing, there are several influencing factors of lifting cylinder hydraulic pressure in the automatic weighing process of LHD. The factors, including engine speed, hydraulic oil temperature, big arm angle, and solenoid valve opening, affected the automatic weighing results. However, the factors were not considered in the past automatic weighing methods. In this paper, the modeling analysis of the automatic weighing process based on multiple parameter coupling was built. By analyzing the production environment, the factor of hydraulic oil temperature was ruled out. Through precise control of the electrical system, the factor of solenoid valve opening was ruled out. Then, through the transformation of LHD and the development of electronic control system, the precise control of engine speed & accurate measurement of big arm angle could be realized. When the mineral weight was 2 000 kg, weight tests were done to find out the optimal interval at different engine speeds & different big arm angles. The optimal interval including engine speed was 1 500 rpm, big arm angle was from 87.5° to 97.5°. By analyzing the weighing experimental data in optimal intervals with 2 000 kg, 3 000 kg, and 4 000 kg, the hydraulic pressure change rule of different conditions was found. The weighing equation was established. The maximum automatic weighing error is less than 1.85%. [ABSTRACT FROM AUTHOR]

An intelligent electronic feeding system has been an ever-increasing pattern in the breeding industry. However, the rotation eating may disrupt the diurnal eating rhythm of some pigs, leading to the health and growth disorder of pigs. This study aims to explore the effects of eating time on the behavior distribution of pig production under the intelligent electronic feeding system. A systematic analysis was also conducted to determine the diurnal proportion of effective and ineffective eating frequency, feed intake, and eating time during the electronic sow feeding (ESF) and pig performance testing station (PPTS). The results revealed that there was the general night eating syndrome of pigs under the rotation eating in the intelligent electronic feeding system, about one-fourth of which ate only at night in the ESF system. The relatively fixed eating order indicated that the herd hierarchy was also an important reason for pig eating time disorder. The ineffective eating behavior of pigs occurred mainly in the daytime, which indirectly increased the likelihood of pigs eating at night in PPTS and ESF. Furthermore, it was probable to reduce the actual number of pigs per station for the less running time of the electronic feeding system and the occurrence of eating at night, according to the operation data from the different areas. More importantly, a further investigation was also made to clarify whether the night time feeding of some pigs under the ESF and PPTS feeding patterns caused the disturbance of sleep schedules and retardation of pig growth. Twenty-six miniature pigs were selected to compare the effects of different feeding time on behavioral rhythm and performance of growing pigs. Two groups were divided into daytime feeding and night time feeding. The former was designed to mimic the natural eating habits of the pigs, while the latter was for the inconsistent feeding time. It was found that the daytime feeding increased by 135.68 g/d (P<0.1) in the daily feed intake of growing pigs, but there was no significant difference in the daily gain between the two groups. The eating behavior of the growing pigs in the daytime feeding group was mostly eating, drinking, and scratching during the daytime, as well as lying at night time. By contrast, the eating behavior of growing pigs in the night time feeding group was mainly concentrated at the feeding time of 19:00 and the alternating time of daytime and night time at 7:00. The daytime feeding increased by 44.28, 14.22, and 61.95 min/d (P<0.05) in the duration of feeding, drinking, and lying, respectively, whereas, decreased by 48.75, 57.40, and 20.30 min/d (P<0.05) in the duration of standing, walking, and scratching, respectively. Therefore, the night time feeding disrupted the normal circadian eating, drinking, and lying behavior rhythm of some growing pigs, particularly for the occurrence of bad mood signals, such as standing and scratching. Consequently, the intelligent electronic feeding system destroyed part of the eating rhythm, leading to the growth difference in individual pigs. Some recommendations were also given to arrange the number of pigs in each feeding station for the optimal running time of the intelligent electronic feeding system during pig breeding.

Aiming at the incompatibility of rime-frequency-space-energy analysis of electromagnetic signals, a data-driven method based on decomposing electromagnetic radiation signals in space-time domain is proposed to analyze complex electromagnetic environment. Firstly, the multi-resolution dynamic mode decomposition method is used to separate the complex electromagnetic signal into modal components of different temporal and spatial scales at different resolutions. Then, the instantaneous frequency and energy characteristics of each mode are collected by using time-frequency distribution. This dynamic decomposition analysis method can quickly detect various electromagnetic environment states of circuits and electronic systems. It does not need a priori data training, is not limited by time-frequency resolution, and can analyze and reduce the data dimension in real time. The extracted dynamic mode and is spectrum have dear physical significance in space domain and time domain respectively. Simulation results show that the average error between the reconstructed signal and the original signal is less than --18 dB, which proves the feasibility and advantages of the proposed method.

Objective: This study aimed to understand the astringency perception difference and formation mechanism of different varieties of Chrysanthemum tea during drinking, and provide new research ideas and theoretical basis for the astringency perception and sensory research of edible flowers. Methods: 5 different varieties of Chrysanthemum were selected to determined the main astringent chemical constituents by UV-Vis spectrophotometry. The perceiving intensity of the astringency of five different varieties of Chrysanthemum was measured and evaluated by using the intelligent taste analysis system of electronic tongue and the traditional sensory evaluation method. The interaction between the main astringent chemical constituents in Chrysanthemum and saliva BCA method was analyzed by SDS-P AGE method, Coomassie bright blue method and fluorescence spectrophotometer method. Results: Among the five kinds of Chrysanthemum, emperor Chrysanthemum and Bozhou Chrysanthemum had the highest content of polyphenol and flavonoids, and the corresponding characteristic value of astringency was also the strongest. The content of polyphenol and flavonoids was positively correlated with the astringency intensity of the Chrysanthemum tea. Conclusion: As the main astringent substance, the difference of polyphenol and flavonoids in different varieties of Chrysanthemum tea significantly affects the astringent taste, and the astringent substance in Chrysanthemum tea combines with proteins in saliva and precipitates, which is one of the main reasons for astringent.

In order to scientifically select the most necessary bus stops to put electronic bus station boards on the premise of limited funds for urban intelligent bus construction, this paper proposes a comprehensive selection index system for electronic bus station boards based on bus big data and GIS. On this basis, a principal component-Two Step clustering combination model is proposed to classify and rank the bus stops. In this paper, the Harbin bus data of 14 days from March 2, 2015 to March 15, 2015 were used for case analysis. A data matching algorithm based on the time difference between IC card and GPS systems without public matching field was proposed. According to the case study results, 1 553 bus stations in Harbin were divided into five categories according to the degree of demand for bus electronic station board. The first category had the highest priority, including 135 stations, but only 8. 69% of the total; the last category had the lowest demand, including 959 stations, accounting for 61. 75% of the total. Firstly, the model constructed in this paper was validated by the indexes of fit and distance of clustering results. In addition, by comparing and analyzing with the actual situation in Harbin, it was proved that the comprehensive selection model of electronic station board put forward in this paper was reasonable, effective and applicable, and can distinguish the level of demand for electronic station board well. The model can provide a scientific and effective method for the construction of bus electronic station board in the case of limited funds for each city. [ABSTRACT FROM AUTHOR]

With the expansion of university scale and the expansion of asset scale, the existing general asset management system no longer meets the needs of stability, safety, networking and personalization. Combined with the advantages of JEE and RFID technologies, Struts2 and Spring open source framework were used to design and implement a lightweight special assets management system for electronic disciplines. The system realizes information synchronization between online management and offline inventory, as well as resource sharing among multi campuses. By optimizing the MVC framework, we solve the problem of overstaffing in the user interface with the increase of code, achieve the separation of levels of the system, and enhance the characteristics of high cohesion and low coupling. Through deployment and internal testing, the system runs stably and reliably, and it greatly improves the efficiency of electronic assets management and reduces the consumption of equipment. The design has a certain promotional value. [ABSTRACT FROM AUTHOR]
