Although the localization of wind power gearboxes in our country has made great progress in recent years, however, there are still many problems that restrict the development of the wind power industry : 1) there is a serious lack of basic research and data accumulation, and there are some limitations in absorbing and absorbing foreign technologies, and there is no independent innovation capability .

summary: It is found that the stress of drill pipe joint is mainly concentrated in the contact position of drill pipe and the stress value of drill pipe joint shows a trend of increasing. However, too large friction coefficient will easily lead to the surface damage of drill pipe joint, and in serious cases, it will cause the skin of drill pipe joint to peel off and accelerate the corrosion of drill pipe, therefore, it is especially important to study the influence of friction coefficient on the process of punching buckle clamp.

flesch: 56
summary: China Abstract: Radiofrequency ablation is a minimally invasive procedure in which tiny radiofrequency electrodes are implanted into the diseased tissue under the guidance of medical imaging (X-ray imager, CT or ultrasound), and neutral electrodes are attached to the skin of the body to carry out radiofrequency ablation, which is carried out by forming a circuit through the human body to the diseased tissue. 2. Hardware Design Since tumor radiofrequency ablation uses a standard sine wave with a fixed frequency, its waveform contains very few harmonic components, so the following relationship exists between its RMS and peak values Vrms = 0.707×Vpeak Therefore, the RMS value of the voltage can be obtained by measuring its peak value and thus the energy output to the lesion can be obtained.

summary: Once the blasting scheme is determined, it is necessary to determine the blasting notch width, because the blasting network is complicated in building demolition blasting, and the number of detonators detonated at one time often reaches thousands [7]. In the process of building collapse, it impacts the ground and produces vibration, and its intensity is higher than that of blasting vibration, and its frequency is lower, which is more harmful to the surrounding buildings and structures, so we must pay enough attention to it.

summary: The catalyst was screened through the viscosity reduction of hydroxypropyl guar gum solution oxidized by H2O2, among which Fe(III)L exhibits high catalytic performance for degradation of hydroxypropyl guar gum in a wide pH range 8.0-12.0, and the viscosity of hydroxypropyl guar gum can be reduced effectively with the 10.0% H2O2 (mass ratio to hydroxypropyl guar gum) in presence of 5.0% Fe(III)L (mass ratio to H2O2). From the result, it can be found that all of complexes show their catalytic performance to degrade hydroxypropyl guar gum in presence of H2O2 under the condition, and the viscosity of hydroxypropyl guar gum solution shows a great decrease from 14 to 1.25 when Fe(III)L was used as catalyst, which is much more potent than the others, therefore it was selected for further investigation.

words: 2898
flesch: 48
summary: Design features of permanent magnet synchronous motors The basic method of electromagnetic design of permanent magnet synchronous motor is as follows: firstly, according to the technical requirements of motor design, the rotor structure and material properties of permanent magnets are determined; secondly, by estimating the electromagnetic load (A,Bδ), the main dimensions (stator inner diameter Di1, motor length Lef) and other motor dimensional parameters are determined.[2] In order to reduce the leakage flux of permanent magnets, the width of the spacer bridge is generally about 1-1.5 mm.[4] For high-speed motors, on the other hand, the isolation measures should be based on the primary condition of ensuring sufficient mechanical strength of the rotor structure.

summary: If the spacing between survey lines is too narrow, although the resolution requirements of the seabed topography are met, it increases overwork and reduces operation efficiency; if the spacing between survey lines is too wide, it greatly reduces the resolution of the seabed topography and cannot guarantee the quality of the measurement results[5].In the more than 40 years of development of multi-beam sounding technology, wide coverage and high precision sounding performance have always been the focus and difficulty of multi-beam sounding technology[6].Therefore, the design and calculation of coverage width and overlap rate in actual detection is of great significance for detection. The shallower the water, the smaller the coverage width of the survey line; The depth of water is unchanged, and the coverage width of survey line is basically unchanged.

summary: This work proposes to adopt the hierarchical attention mechanism to enable the code summarization framework to translate three representations of source code to the hidden spce and then it injects them into a deep reinforcement learning model to enhance the performance of code summarization. However, these kind of approaches have the following drawbacks: (1) they mainly take the source code as plain text and ignore the hierarchical structure of the source code; (2) most of the approaches only consider simple features,such as,tokens,which overlooking the hidden information that can help grab the relationships between source code and comments; (3) they typically train the decoder to produce the code annotation by calculating and maximizing the odds based on the subsequent natural language words, however in fact, they mainly produce the code annotation from scratch.

summary: Cascade control PID control waveforms From the above two graphs, it can be seen that under the action of the same PID control parameters, the regulation time of the series control is about 200s, and the regulation time of the single-loop PID control is about 1450s, and the overshoot, volatility, and steady-state error of the series control are smaller compared with that of the single-loop control, which can be seen that the rapidity, stability, and accuracy of the series control are better than that of the single-loop control system. Although there have been many researches on liquid level control system, there are still some problems in practical application, such as low control accuracy, poor stability, slow response time and so on[1].

However, the residual carbon is generally high and viscous, and a certain percentage of diluted oil (wax oil, catalytic cracking slurry, etc.) needs to be blended as fixed-bed feed, and the installation and operation costs are very high, thus increasing the cost of producing heavy fuel oil, so the direct production of heavy marine fuel oil with sulfur mass fraction below 0.5% by fixed-bed hydrogenation is worth further consideration[2].

summary: As the number of cycles increased, the proportion of small particle size particles in catalyst particles gradually decreased, especially in the first cycle of particles, the area occupied by small particle size particles was much smaller than the original particle size distribution, This indicates that the proportion of small particle size in the equilibrium catalyst gradually decreases, which also indirectly indicates that under higher gas flow rates, small particle size is more likely to escape from the cyclone separator, leading to a higher loss rate. The experimental material used was equilibrium catalyst, with the typical fault feature of cyclone separator gas leakage of dipleg.

summary: The power model of UAV flight is established through MATLAB/Simulink, and the flight curves of two variable loads are demonstrated through the design, and the curves can intuitively detect the state of the UAV, and detect the stability of the UAV's fuselage in the case of variable load, which provides evidence for the stability of the UAV. Through experiments using UAV flight models it can be found that, the UAV can quickly adjust the flight state, so that it has been flying smoothly without losing control, which also proves that the model can be visualized to observe that the UAV will not affect the stability of the UAV's flight because of the changes in its own mass when it changes loads.

summary: This shows that because of the increase of blade wall thickness b, the blade conductivity and energy conversion ability are enhanced, but the crowding between the blades is also enhanced, which will also lead to the increase of hydraulic loss between the guide vanes, so the efficiency of the tool η changes little. When the blade wall thickness b continues to increase to 10.0mm and 12.5mm, the efficiency of the tool is stable to 69%, With the increase of blade wall thickness b, the efficiency η generated by the tool decreases first and then tends to be stable.

summary: In addition, as the network gets deeper, there is a problem of gradient disappearance in the process of down-sampling, which will lead to a reduction in the network's ability to extract brain tumor features. This study proposed a mixed loss function by combining Dice loss and Cross-entropy loss, and the mixed loss function can consider the weight information of the categories of brain tumors, and fully suppress the effect of category imbalance on brain tumor segmentation.

summary: It is concluded that with the increase of immersion time, the water content increases, showing a trend of rapid growth in the early stage and slow growth in the later stage, and the compressive strength of concrete decreases with the increase of water content, and the compressive strength of saturated concrete is only 75% compared with that in the dry state. The results show that under quasi-static loading, the free water in the pores and cracks is similar to the wedge effect of the wedge, which accelerates the propagation of microcracks and reduces the strength of saturated concrete.

summary: The pathway parallel technique [3-4] refers to the formation of multiple narrowband LNAs into arrays, each of which is individually designed according to the application criteria and frequency bands with independent DC bias and signal paths, i.e., separate amplification of signals at different frequencies, which is the most traditional scheme for realizing band reconfigurable LNAs. The matching network reconfigurable technique requires fewer passive devices, high circuit utilization, and low power consumption, but it can only amplify narrowband signals at the same time, which is not suitable for simultaneous operation in multiple frequency bands; in addition, similar to the load network reconfigurable technique, the on-state resistance of MOSFETs deteriorates the NF.

summary: In terms of pore capacity of coal samples, CO2 adsorption time, CO2 adsorption pressure and CO2-H2O treatment do not show obvious regularity in the changes of pore capacity of coal samples, but in general, the increase of CO2 adsorption pressure and CO2-H2O treatment have a positive effect on the increase of pore capacity of coal samples, especially ScCO2-H2O. Extending CO2 adsorption time, increasing CO2 adsorption pressure and CO2-H2O treatment all have positive effects on the increase of macro pore volume of coal sample.

flesch: 41
summary: From the comparison between the bulk density and apparent density of arsenic sandstone and composite soil, it is found that the bulk density and apparent density of arsenic sandstone are both greater than the surface density of composite soil, indicating that although the total porosity of arsenic sandstone is greater than that of composite soil, the actual unit weight of arsenic sandstone is greater than that of composite soil, that is, arsenic sandstone is relatively dense, the mass per unit volume is greater than that of composite soil, 221 and the clay content is greater than that of composite soil, which explains the internal reasons for the macro performance of arsenic sandstone. The total porosity of arsenic sandstone is larger than that of composite soil, but its porosity is far less than that of composite soil, which further verifies that arsenic sandstone has many large pores, compact texture and strong water permeability; However, the composite soil has many micro pores, loose texture and weak water permeability. 5000x 2000x 1000x 500x Figure 1.

summary: In order to study the deterioration and damage process of fly ash concrete under the condition of freeze-thaw cycle with large temperature difference, we take the Ruoqiang area in Xinjiang, China as the research background (temperature difference: -23.3℃~43.1℃), study the dynamic evolution process of corrosion resistance coefficients of the concrete specimens with fly ash dosage of 0, 10%, 20%, and 30%, and analyse the law of frost resistance decay of fly ash under the environment of freeze-thaw with large temperature difference; the results show that the addition of The results show that: adding 10%~20% of fly ash in concrete can slow down the deterioration of concrete frost resistance, and the frost resistance of concrete is the best under 20% of fly ash dosage. Based on the indoor large temperature difference freeze-thaw test to analyze the effect of different fly ash admixture on the corrosion resistance coefficient of concrete, Figure 3 shows that: in the corrosion resistance coefficient increase stage, 0%, 10%, 20% and 30% fly ash admixture concrete are in the 90th cycle to reach the maximum value of corrosion resistance coefficient, respectively, 1.12, 1.11, 1.15 and 1.17, increase in the range of 12.8%, 11.6 15.3% and 17.3%, and the development trend is 30%>20%>0%>10%; from the analysis of the peak corrosion resistance coefficient, it can be seen that: the concrete with 30% of fly ash has the largest corrosion resistance coefficient; from the analysis of the development trend, it can be seen that: the corrosion resistance coefficient grows more before 60 times of freeze- thaw cycles, and grows slower in the 60-90 times of cycles.

summary: This is a direct result of the twofold nature of the intricacies in avilamycin production: on one side, the existing strains of Streptomyces viridochromogene will reach their physical limitation in volume; on the other, the industrial scaling of the production processes has stayed slow and inefficient. They have effectively been demonstrated to increase the resistance of the bacteria against competitive antibiotics, like streptomycin, and yet lead to substantial increases in avilamycin production.

summary: By optimizing the BP neural network model, it is found that the network performance is optimal when the number of neurons is 14 and the number of hidden layers is 4.Its experimental results show that the heat sink coated with graphene film has 4.12% higher thermal performance than the heat sink without graphene film [7].The heat dissipation effect of graphene varies when it is coated in different positions of the heat pipe heat sink, with the best heat dissipation effect of fully coated graphene [8].The flexibility and high thermal conductivity of graphene film are utilized to design heat sink structures adapted to different shapes and sizes, such as flat plate, finned, and curled. Combining the hybrid structure of graphene film and conventional heat dissipation materials, along with alternately arranged multilayers of graphene and high thermal conductivity fillers, the mechanical strength and stability can be enhanced while maintaining high thermal conductivity.

summary: From the perspective of sucker rod pumping unit production operation, a literature review is conducted on the flow patterns in the wellbore, pump efficiency analysis, and intermittent oil extraction systems, clarifying the optimization objectives of liquid production and system efficiency, and sorting out from the aspects of dynamic liquid level, pump efficiency, reasonable submergence depth, and intermittent operation systems. Key factors affecting pump efficiency [8][9]: First, the sucker rod and tubing undergo elastic deformation under cyclic loading, which affects the effective stroke of the plunger and reduces the volume of discharged liquid; second, if the pump chamber intakes a mixture of gas and liquid or the reservoir supply is insufficient, it will affect the flow of liquid into the pump chamber; in addition, gaps within the pump and wear of components may lead to a decrease in flow, and the pump body may be damaged by corrosion and sand particles during long-term operation, affecting the stability and efficiency of the pump; finally, due to the action of reservoir pressure, gas is compressed into the fluid during the pumping process, and crude oil will shrink in volume after being lifted to the ground due to degassing, which also affects the calculation of pump efficiency.

summary: This is because after Spearman correlation analysis, the characteristic compounds that have a greater influence on the classification of raw wine grades are retained, so that the principal components after secondary feature extraction can better characterize the change of the quality of raw wine; the prediction accuracy of the model established by Spearman-KPCA combined with SVM, XGBoost and BP neural network is higher than that of Spearman-PCA, and this may be due to the fact that the change of the content of the substances in the raw wines of different grades is not simple linear increase or decrease. [12] applied GC- MS spectrum technology to the identification of Xiaoqu pure flavor raw wine of different grades, and established a grade discrimination model of Xiaoqu pure flavor raw wine in combination with PL-DA to achieve accurate identification of raw wine samples.

summary: Adding SDS into vanilla essential oil according to a predetermined concentration gradient, and ensuring full and uniform mixing, so as to prepare vanilla essential oil samples with different SDS concentrations; The fragrance retention performance of the samples in the control group and each experimental group was regularly detected and recorded by the olfactory evaluation method [5]; Finally, the data of fragrance retention performance of vanilla essential oil under different SDS concentrations were compared and analyzed to clarify the specific influence law of SDS concentration on its fragrance retention performance. In the control group, in the absence of SDS, the fragrance retention effect of vanilla essential oil gradually decreased with time, showing its natural volatilization characteristics; However, at the concentration of 0.1 mM SDS, although the fragrance retention ability was only slightly improved, it has been shown that low concentration SDS is helpful to enhance the dispersion of vanilla essential oil molecules, thus promoting fragrance retention; When the concentration of SDS is increased to 0.5 mM to 1 mM, the effect of prolonging the fragrance retention time of vanilla essential oil is significantly enhanced, because there is a good balance between SDS and vanilla essential oil molecules, and the formed micelle can not only protect the vanilla essential oil molecules from rapid volatilization, but also ensure their moderate emission to achieve a more lasting fragrance retention effect; However, at the high concentration of 5 mM, although SDS can still play a certain synergistic role, the excessive micelle formation leads to the excessive encapsulation of vanilla essential oil molecules, which hinders its normal volatilization, making the fragrance retention performance slightly lower than the previous two concentration ranges.

summary: Through systematic organization and in-depth analysis of rural crop cultivation and related statistical data collected in 2023, it was found that different types of crop planting plots have no significant impact on sales prices but do affect planting costs and yield per acre. After a detailed comparative analysis, we found that the sales prices of all crops remain constant across different planting plots, while the planting costs and yields per acre in plots E and F are higher than those in plot D. From this, we can infer that the type of crop planting plot has no significant impact on sales prices.

title: Research on Skeleton Plate Flatness Detection Method Based on Laser Sensor
date: 2022
words: 1772
flesch: 49
summary: China Abstract: The flatness of the seismic isolation support skeleton plate determines the seismic isolation performance of the seismic isolation support, and in view of the limitations of the traditional measurement method in the engineering field, the use of laser sensor and computer-related processing technology is proposed to solve the problem of flatness measurement of the seismic isolation support skeleton plate. [7] The ideal plane selected by the three-remote point method and the diagonal method does not comprehensively use the detected plane data, and the flatness error may cause a large evaluation difference according to the different reference data points selected each time, which is generally only suitable for flatness error measurement with a small number of plane distribution points and low plane accuracy requirements.

summary: zyy1050885023@163.com Abstract: Taking the giant thick conglomerate in Yima mining area as the research background, this paper investigates the acoustic emission characteristics and crack evolution law of conglomerate with different grain sizes under loading conditions through uniaxial compression test and acoustic emission (AE) technology, and discusses the influence of grain size on its damage mechanism and damage evolution. Kang et al[4] conducted high-temperature treatment on granites with different grain sizes, and found that the weakening of the heated granite is more serious with the increase of the grain size; Sabi et al[5] Brazilian splitting experiments, indicating that coarse-grained granite produces more cracks, and with the increase in grain size to induce the production of tensile cracks, the number of shear cracks also increased; Deng et al[6] three-point bending experiments on four different grain sizes of granite, found that with the increase in grain size, the peak load, fracture toughness value, the ratio of yield limit and peak load are reduced, the amount of deformation occurred in the damage increases The non-homogeneity of the specimens is more obvious; Zhao et al[7] investigated the role of particle size in controlling the permeability of sedimentary rocks through core size analysis and extraction of logging geologic parameters, and established a model for calculating the particle size and permeability, which revealed its non- homogeneity characteristics.

summary: According to the results of multiple milling experiments, and considering factors such as surface roughness, tool wear and tool vibration, the milling parameters such as cutting speed, milling depth, and feed per tooth are set as fixed values. When the oil flow rate is greater than 140ml/h and less than 200ml/h, the axial vibration amplitude gradually increases with the increase of oil flow rate, but the radial vibration amplitude starts to decrease, which may be due to the reduction of tool wear leading to the reduction of radial vibration; When the oil flow is greater than 200ml/h, the axial vibration amplitude is inversely proportional to the increase of oil flow, while the radial vibration is proportional to the increase of oil flow.

summary: Displacement of roadway surface at station 3# 7. Conclusion Numerical simulation software is used to carry out numerical analysis models for different coal pillar widths between strip lanes, and study the schemes for maintaining coal pillar widths in various sections, providing basis for the final determination of reasonable coal pillar widths and drawing conclusions: (1) The comparative analysis of surrounding rock stress of coal pillars with different widths between strip lanes shows that: after the excavation of strip lanes, once the width of coal pillars is less than 5 meters, the internal vertical stress of coal pillars is generally at a low level, and the peak stress is lower than the initial stress. In the engineering practice of coal mining, strip coal pillar plays an important role in carrying and supporting.

summary: China *Corresponding author Abstract: To conduct a more accurate and effective embrittlement mechanism analysis of the shield construction system for parallel gas pipelines (SCSPGP), combined with previous accident investigation reports, system-level accidents and hazards were determined, unsafe control behaviors during shield preparation and shield tunneling were identified through building a control feedback model, and a list of embrittlement factors from the four dimensions of physics, psychology, human, and environment was constructed; Considering the uncertainty of human evaluation, the IPFS (Interval Pythagorean Fuzzy Set) was introduced to propose an improved DEMATEL-ISM (the Decision Making Trial and Evaluation Laboratory and the Interpretative Structural Model) method. Compared to risk research, vulnerability research focuses more on the flaws, weaknesses, and the ability of the supporting structure to handle risks, mainly focusing on the identification of embrittlement factors and vulnerability assessments.

Logging responses of black shale include: High natural gamma (180- 330 API) and acoustic moveout values (280-340 μs/m), Low density (2.2-2.4 g/cm ³ ), Negative spontaneous potential anomalies (Table 1). 3.2.

summary: The method enhances the network's focus on key fault features by introducing the SE module to adaptively adjust the weights of each feature channel in the convolutional network, which optimizes the feature extraction ability of the model in complex vibration signals. Traditional bearing fault diagnosis methods rely on signal processing techniques and empirical feature extraction, but in practical applications, with the change of working conditions, the signal features often appear to be mixed, which brings a greater challenge to the diagnosis.

summary: Crop correlation analysis First, substitution and complementarity are explained[4]: substitution refers to the fact that if there are many substitutes for a good, an increase in price may lead to a decrease in sales as consumers may switch to other options; complementarity refers to the fact that if a good is complementary to other goods, an increase in price may reduce sales of the complementary good and thus overall sales. Observation of Figure 3 shows that the total crop yield is highest in irrigated land, followed by crop yield in terraced land and lowest in greenhouses.

summary: When the jet working pressure exceeds 50 MPa, the solid-liquid mixture within the rock fissures similarly weakens the impact velocity of subsequent abrasive water jets; however, under higher impact dynamic pressure, the stagnation pressure within the rock fissures significantly increases, which is beneficial for secondary fracturing of the rock, possibly being the main reason for the rapid increase in rock cutting depth once again. Therefore, the inflection point where the rate of increase in rock cutting depth due to increasing waterjet horizontal movement speed is the optimal horizontal movement speed for the waterjet.

summary: When the service-oriented leadership level is high, the stationmaster will authorize his subordinates to help deal with the illegal records in the algorithm system and give the rider the space to arrange his work independently; Help take-away riders coordinate work arrangements, deal with unexpected situations and unreasonable algorithm commands, so that take-away riders can finish their work tasks more easily and gain a sense of accomplishment; Respecting the dignity and values of takeaway riders makes it easier for takeaway riders to perceive the atmosphere of psychological safety, equality, fairness and trust when they get along with webmasters and colleagues (Ehrhart, 2004). Based on the theory of self-determination, this paper intends to explore the influence of algorithmic control on the workplace deviant behavior of selling riders, reveal the intermediary role of psychological needs to meet the above relationship, and demonstrate the regulatory role of service- oriented leaders in this process, with a view to enriching the research on algorithmic control and workplace deviant behavior, and providing data reference for the optimization direction of the algorithm of odd jobs platform, and enriching management experience for managers.

summary: Uncertainty from learned fusion is often miscalibrated and therefore over‑confident; distribution shift across weather, lens contamination, and rare targets remains under‑represented in training and evaluation; black‑box fusion complicates safety cases and public trust; and embedded compute budgets make some accurate raw‑level approaches impractical at ASIL‑D deadlines. Redundancy and data fusion counter this fragility by arranging for alternate coverage, by cross‑checking disagreeing measurements, and by enabling graceful degradation when one channel becomes unreliable.

summary: If the staff close to the fan coil feels too hot, they can adjust the independently controlled deflector to directly send part of the cold air to the working area close to the fan coil, as shown in Figure 4, which improves the comfort of air supply. Although the outlet hot air temperature is higher than the human body temperature when the existing fan coil is used for air supply, the air temperature reaching the human body area will be lower than the human body temperature to some extent due to the sufficient mixing of indoor cold air along the way, resulting in a certain degree of blowing feeling.

date: 2023
words: 4585
flesch: 48
summary: It has been reported that ethanol in the process of stimulating GES-1 cell injury will be accompanied by cell apoptosis and necrosis, but a high concentration of ethanol will directly contact the gastric mucosa, resulting in cell degeneration and necrosis, which is disadvantageous to the recovery of normal body. In order to detect the protective effect of DHQ on ethanol- induced GES-1 cell injury, 10 μL of the final concentration of 1, 10, 50 and 100 μM was added into each well for 3 hours, then 10μL of ethanol with the final concentration of 6% was added to each well for 1.5 h.
