There is little research about using information technologies in music education. The issue of comparing the approach to music education based on modern technologies with the traditional approach is of particular interest. Thus, the purpose of the study is to compare the effectiveness of music education based on modern technologies with the traditional approach to learning music. The study was conducted at Lishui Music School. The level of musical skills and abilities of music school students was assessed for the period of 1.5 years. The study involved children aged 5-6 years who had no prior musical experience. The control and study groups consisted of twenty-four children each. The children learned to play the piano and solfeggio. The study group trained in accordance with the New way of Music program. The control group followed the traditional curriculum. At the end of the study, there was an exam. The students performed program pieces corresponding to the study period. The expert committee evaluated the following performance parameters: the number of errors in the reproduction of the musical text, the performance rhythm, the artistic expressiveness of the performance, continuous and complete performance, the performance dynamics, mastery of strokes, as well as positioning of the body and hands during the performance. Except for the last parameter, the study group performed better than the control group. The results obtained justify further expanded studies of the New way of Music program to be subsequently widely introduced in music schools.

The Water Margin portrays many typical female images, and different female character images make the characters more fleshed out so that the readers will never forget them. In this paper, we construct cognitive mapping based on the cognitive mapping of female characters in Water Margin. In order to more intuitively display female characters and their embedded cultural characteristics, we choose a multilayer perceptual machine to learn the representation of emotion score vectors and combine the temporal and semantic relationships in the text with long and short-term memory networks to construct an emotion dictionary of female characters. GAN is utilized in female characterization to provide a foundation for thoroughly analyzing the cultural characteristics of female character roles. The method given in this paper was validated and analyzed in terms of female characterization and cultural characteristics. The results show that on the EmotionROI dataset, the classification accuracy of the emotion lexicon is 9.34% higher than that of the GOSR algorithm, and the classification accuracy of various emotion categories reaches more than 70%. The image generation quality of the GAN method is 63.96% on the BLUE-4 dataset, and the final CIDER index score on the MSVD dataset tends to be 1.15%. The image of female characters in Water Margin mainly conveys a variety of different images such as heroic, ugly and complex, which represents the real state of women at the bottom of society in the feudal period of the late Yuan and early Ming Dynasties, and provides a certain reference for understanding the cultural traits under the feudal society.

The horizontal rotating disc contactor (HRDC) for extraction consists of a mixing chamber and two settling chambers, which enables continuous cycling of the dispersion-mass transfer-separation processes and achieves higher mass transfer efficiency compared to a single equilibrium stage. For O/W emulsion systems, it allowed for continuous separation of the oil phase. In order to further improve the separation performance of the extractor, the structure was optimized by simulating the coalescence and breakup process of O/W emulsions using computer software. A two-dimensional model was established to study the effects of flow rate, droplet size, and wall wettability on coalescence efficiency in kerosene/water systems. The results showed that coalescence efficiency in narrow channels initially increased with flow rate before decreasing, indicating an optimal flow rate exists. When droplet size was smaller than channel dimensions, larger droplets were more prone to coalesce. Additionally, hydrophobic walls exhibited better coalescing effects. These findings provided theoretical support for optimizing HRDC equipment and achieving continuous extraction in different O/W emulsion systems.

The horizontal rotating disc contactor (HRDC) for extraction consisted of a mixing chamber and two settling chambers, which enabled continuous cycling of the dispersion-mass transfer-separation processes and achieved higher mass transfer efficiency compared to a single equilibrium stage. The extraction efficiency of benzoic acid/n-heptane/water system was measured by an HRDC extractor, and the two-phase concentration could be measured by spectrophotometer. The experimental results showed that the extraction efficiency of benzoic acid/n-heptane/water was 46%.

Abstract Inertial support for hybrid AC/DC microgrid systems is provided by the virtual synchronous generator (VSG). However, the fast performance of the system is neglected while enhancing the stability of the system. To address this problem, an adaptive virtual inertia control strategy based on VSG technology is proposed. This control approach adaptively adjusts the system virtual inertia when the system operation deviates from the nominal value, by slowing down the rate of change of AC frequency and DC voltage and improving the deviation of AC frequency and DC voltage. Meanwhile, when the AC frequency and DC voltage restore back to the rated value, the rate of change of AC frequency is accelerated and the DC voltage fluctuation is reduced by dynamically adjusting the virtual inertia of the system. The proposed adaptive virtual inertia control method combines the advantages of large and small inertia to effectively improve the dynamic response of the system voltage and frequency in both rectifier and inverter modes. Finally, the simulation and experimental results verify the effectiveness of the proposed control algorithm.
