Abstract: In the current educational reform wave, which prioritizes moral development as the fundamental goal and stresses the enhancement of core student competencies, aligning higher education management with student cultivation mechanisms is crucial to educational progress. The Lucas-Kanade (LK) optical flow algorithm is used in this paper to gather behavioral characteristics from student interactions within the cultivation mechanism. A multi-scale convolutional kernel approach is used to fuse these features both locally and globally. A multi-scale feature fusion module subsequently classifies and recognizes these features, with recognition accuracy optimized by a tailored loss function. This approach allows for the timely identification and analysis of students’ aberrant behaviors, which aids in prompt educational interventions. The multi-scale feature fusion model can effectively identify various types of aberrant student behaviors, which aids educators and institutional leaders in their management efforts, as revealed by experimental findings. Statistically, the model’s implementation led to significant improvements in classroom routine compliance, with pre-and post-test p-values in the experimental cohort showing a notable difference (p = 0.001; p < 0.05). The proposed multi-scale feature fusion model promotes the integration of management and training mechanisms in higher education while also supporting the development of students’ learning capabilities. This innovation sets a solid foundation for future educational advancements. PubDate: Mon, 05 Aug 2024 00:00:00 GMT
Abstract: Big data technology has brought new opportunities for the development of the education industry and can play a positive role in the management of student campus education. In this paper, the behavioral features in the extracted multi-source behavioral data of college students are dimensionality reduced using principal component analysis, and the behavioral features are clustered using density peak clustering and undersampling methods. The Adaboost algorithm is used to identify and classify each behavioral feature to obtain behavioral analysis data for students. Finally, the university’s education management system is constructed based on this behavioral analysis model. The behavioral analysis of students in a university shows that both consumption behavior and book borrowing behavior cluster into three categories. Among them, the type of students who clocked into the library with a medium frequency and borrowed the most number of books had the highest percentage (39.25%) among the students in this university. And there is about a 79.3% probability that students of the university with a high number of absences seldom visit the library. The study also showed that there was a significant difference (p<0.05) in the study behavior of students in both experimental and control classes after the application of the educational management system. The student behavior analysis and management platform proposed in this paper effectively promotes the development and progress of education management in colleges and universities and improves the efficiency of student management work and the scientificity and reliability of the results.

Abstract: In recent years, with the rapid development of the Internet and education informatization, online teaching has become a popular education mode in the information age, providing learners with very rich teaching resources. In this paper, we construct a personalized system and co-recommendation technology for English teaching resources, and we improve the traditional co-recommendation algorithm and propose hybrid recommendations. The performance of the system is evaluated experimentally to compare the effectiveness of the performance of the four systems. The improved recommendation algorithm is superior to the other three recommendation algorithms in each dataset in the system. The average grade mean of the experimental class assisted by the hybrid recommendation system in teaching English in colleges and universities in the latter two experiments is 27.54, which is higher than that of the comparison class of 25.33, and the T-value is 1.81>1.645. The improved personalized recommender system has good validity and stability in both performance and practical application. PubDate: Mon, 05 Aug 2024 00:00:00 GMT
Abstract: The improvement of China’s economic level makes the society’s requirements and standards for infrastructure constantly improve. In order to effectively promote the rapid development of the rural economy, it is necessary to strengthen the construction of rural infrastructure. This paper provides a comprehensive plan for rural infrastructure construction and analyzes its mechanism of action on rural economic development in depth. Taking rural economic growth as the explanatory variable and infrastructure construction as the explanatory variable, the multiple linear regression model is chosen to analyze the impact of rural infrastructure on rural economic growth. The unknown parameters are estimated by the least squares method. The model is tested and modified based on the diagnostic methods of covariance expansion factor and other covariates to obtain the final results. Through empirical analysis, rural economic growth = -15.1935 + 0.184*rural transportation + 0.0983*rural education + 2.4923*agricultural science and technology + 0.3652*agricultural water conservancy, and agricultural science and technology has the greatest impact on rural economic growth. The local area can improve rural infrastructure in three aspects: investment strength, investment focus, and investment and financing mechanisms. PubDate: Mon, 05 Aug 2024 00:00:00 GMT
Abstract: In recent years, target detection algorithms based on machine vision have been a hotspot in computer vision research. The You Only Look Once (YOLO) algorithm, as an excellent target detection algorithm, has played an important role in improving detection speed and accuracy with the improvement of the network architecture in its development process. This paper introduces the concept of integrated learning to the YOLOv5 network architecture, incorporating deformable convolution and attention mechanisms. It also chooses the focal EIOU loss function to replace the GIOU loss function, thereby addressing the issue of localization loss, prioritizing abnormally detected targets, and enhancing the detection efficiency of these abnormal targets. Finally, we examine the practical value of the improved YOLOv5 algorithm by testing its performance and applying it to real-world anomaly detection. The results show that the improved YOLOv5 model outperforms the original YOLOv5 model in terms of performance and practical application advantages. In terms of performance, the classification accuracy of sea_person and earth_person in the improved YOLOv5 model is 37% and 26%, respectively, which is a significant performance gain overall. In actual application tests, the proposed method is more accurate than the traditional method. The accuracy is significantly higher. PubDate: Mon, 05 Aug 2024 00:00:00 GMT
Abstract: Inventory management plays a very important role in the process of business operation, providing favorable backing for the smooth operation of production and sales.

Abstract: Exploring the development of tourism-based urbanization and improving the overall competitiveness of regional tourism is a major initiative to promote the development of tourism in countries in China. In this paper, we take the urbanization pattern of tourism as the background, water yield, soil retention, and habitat quality as the factors, and use a bivariate spatial correlation model to explore the spatiotemporal association between the urbanization pattern of tourism and ecosystem services, so as to provide a reasonable reference for the development of the urbanization pattern of tourism from the perspective of ecosystem services. It was found that the construction of tourism urbanization pattern increased water production and soil retention by 17.07% and 23.08%, respectively, compared with 2000. In addition, habitat quality contained the highest ecological service value of woodland, which provided 81% of water production and 470.79 g·m−2 of carbon storage. Throughout the period, the spatial distribution pattern of soil conservation and habitat quality remained largely unchanged, and the synergistic trade-off relationship between ecosystem services demonstrated spatial heterogeneity. The interaction relationship was dominated by synergistic relationships, with a small number of districts and counties existing as a trade-off. The study measures how ecosystem services change over time and space in Province A. It also explains how trade-offs and synergistic relationships between ecosystem services work. Finally, it gives a good scientific basis for the growth of high-quality ecological services and tourism in a region that is rapidly urbanizing. PubDate: Mon, 05 Aug 2024 00:00:00 GMT
Abstract: The rapid development of virtual reality and augmented reality technology has brought significant changes to many industries in modern society. In the field of product packaging design, the use of virtual reality and augmented reality technology in product packaging design is becoming more common in the field. Researchers are exploring the use of VR and AR technology in children’s drug packaging, employing augmented reality research that leverages natural features and artificial recognition to construct a model of children’s drug packaging that incorporates VR and AR technology. We analyze the impact of VR+AR on children’s drug packaging. Consumers’ main requirements for children’s drug packaging are bright, strong, practical, fun, novelty, and ease of understanding. The paper’s model, sample Z, ranks 5th in market competitiveness and 1st in technical competitiveness, outperforming competitors A, B, C, and D. This suggests that VR+AR children’s drug packaging still needs improvement in market competitiveness despite its high technical content. In descending order, the design evaluation dimensions score the VR+AR children’s drug packaging as follows: vivid picture (3.193)> texture (3.154) > easy to hold (3.142) > Moderate capacity (3.129) > simple and generous (3.105) > conform to the production process (3.047) > harmonious color (3.044) > convenient for transportation (3.028) > low production cost (3.012). The average score for each dimension of the VR+AR children’s drug packaging experience is approximately 4.46 points. PubDate: Mon, 05 Aug 2024 00:00:00 GMT
Abstract: More and more modern technology is applied to traditional cultural and creative industries, which enhances the technicality and novelty of traditional cultural products, and the fusion of culture and modern technology profoundly changes people’s way of life and learning. This paper explores the Internet of Things (IoT) technology and the intelligent transformation process of cultural and creative products and constructs cultural and creative products that integrate intelligent voice series. Specifically, a speech recognition model is integrated into the design process of cultural and creative products, and the designed model is applied to the design of intelligent cultural and creative products by analyzing the Hidden Markov Model (HMM), proposing a solution to the shortcomings of the HMM model, and choosing to perform noise reduction of speech signals through the fixed beam algorithm. Based on the speech recognition model designed in this paper, an intelligent cultural and creative product with a speech recognition function is designed, taking the ‘owl wine container’ from the Shanxi Museum as an example. The regression equation of the audience’s satisfaction with the product is Y (satisfaction) = -0.000263 + 0.208X1 (practicality) + 0.265X2 (innovation) + 0.253X3 (culture) + 0.271X4 (interactivity) - 0.296X5 (fun). This paper’s intelligent cultural and creative products have a greater impact on satisfaction due to their innovativeness and interactive function. PubDate: Mon, 05 Aug 2024 00:00:00 GMT

Abstract: Exploring the evolutionary process of the concept of science and technology in modern Chinese society is conducive to the innovation of the current path of science education popularization and scientific and technological literacy enhancement. In this paper, we construct a sampling selection algorithm using Bayesian and MCMC and then design a parameter derivation model. Assuming the model prior distribution hyperparameters and using the likelihood function to derive the specific form of the posterior probability distribution, an approximate integral calculation is carried out in order to directly derive the parameters to be estimated, and the BVAR-MCMC model is constructed. Using the model to analyze the temporal changes in the evolution of scientific and technological concepts in modern China, it is finally found that the changes in social and technological concepts during the Republican period were even stronger than those in the late Qing period. Influenced by the increasing scale of cross-cultural exchanges due to the gradual opening up of the gateway, cross-cultural open exchanges have the highest impulse value and the longest duration on the evolution of scientific and technological concepts, with the impulse of the Late Qing and the Republic of China phases above 1, and the duration of the positive influence covers the whole time series. The impulse values of the late Qing and the Republic of China are 2.68 and 3.59, respectively, and the education popularization rate, economic development level, the speed of technological life progress, and the degree of civilization and freedom of the social atmosphere have different degrees of influence on the evolution of scientific and technological concepts in the time series of modern history. This study innovates the statistical research method for modern history and conducts a pioneering exploratory study on the evolutionary process of modern social ideas change.

Abstract: At present, the daily operation and maintenance of large-scale data centers such as banks in China, due to a variety of reasons, often brings about the problem of unexpected events that are difficult to locate. In order to ensure that the systems running in the data center work efficiently, this paper proposes a method for improving the operation, maintenance, and monitoring of financial data centers based on the cloud-native model. First, we sequentially cleanse and process the financial center data to eliminate any negative impact and generate a time-trending correlation of financial attributes. We then apply association mining to data center operation and maintenance, using stock information as an example to analyze the operational results in stock trading transactions. The result of correlation mining is component B index (up)⇒ component A index (up), support = 12/100, confidence = 12/19, which indicates that in 100 trading days, the number of days that the component B index and the component A index rise together is 12 days, while the number of days that the component B rises alone is 19 days. In the case study examining the impact of association mining in stock trading, on March 15, 2022, the stock price experienced a rise from 11.456 to 11.498 within a mere 0.1s. The financial data operation and maintenance system, using association mining, identified this as “abnormal,” demonstrating the model’s successful detection of abnormal behavior.

Abstract: Coal is an important energy resource. How to utilize it efficiently and cleanly is a hot topic nowadays. In the coal gasification process, the process parameter indexes have a significant impact, and the uncertainty of these factors will lead to a decrease in the quality of gas production. Therefore, in this paper, the uncertainty of process parameters is considered, and Aspen plus software with the Monte Carlo method is used to simulate the coal chemical process and measure the effect of uncertainty of process parameters on the yield of the coal gasification process. On this basis, in addition, coal flow rate, pressure, and steam/oxygen are taken as the process parameters and optimized, and three sets of multi-objective optimization models are established with gas calorific value, gasification efficiency, and gas yield, respectively, which are solved by improved multi-objective genetic algorithm based on crossover operator and variational operator to obtain Pareto curves, so as to adjust the parameter values according to the actual needs. The results show that the fluctuation of pressure has a big influence on the carbon conversion rate and gasification efficiency, and the carbon conversion rate and gasification efficiency can be made more stable by controlling the change of pressure. The improved genetic algorithm NSGA-II can reach the actual optimal objective function value in both high and low iteration times, providing the required parameters for the decision maker, and the optimal program results in TEC of 402,758 kW and CO2 content of 0.12%, which is effective in energy saving and emission reduction.

Abstract: Due to the challenges associated with mastering fundamental piano playing techniques, the inefficiency of self-guided learning, and the prohibitive cost of one-on-one instruction, many novices abandon their musical pursuits prematurely. Our research addresses these issues by enhancing music feature extraction methods through artificial intelligence modeling and developing a piano-playing ability evaluation system. This system leverages an attention mechanism and an LSTM neural network model to assess a player’s abilities based on rhythm, thematic prominence, and musical expression within various levels of piano scores. By analyzing sample tracks from the Thompson Simple Piano Tutorial, our system demonstrates robust performance, achieving an overall F-Measure above 0.9 with an average value of 0.9641. These results indicate that the evaluation system offers precise assessments and can significantly aid piano instruction, providing learners with reliable feedback on their progress.
