“…Top teams often use some special tactics, such as the "two hitters for three" attack tactics in the front and back rows, arrange setters and attacking players in specific rotation, and maximize the richness of attack means in each rotation of the teams. (3) ere is an interaction effect among tactical factors in volleyball matches. e interaction effect is different between tactical standard and utilization and different sections.…”

“…Random matrix theory is mainly applied in quantum physics [3], biomedicine [4], social science [5], power grid distribution [6], spectrum perception [7], and other fields. Using a large number of fault and defect samples, the corresponding relationship between the confidence level of the key performance of the equipment and the state quantity is mined through association rules, and then the time series of the state quantity of the equipment is processed through the high-dimensional random matrix theory.…”

It is the trend of the development of modern competitive sports to put scientific and technological analysis methods and means into the study of volleyball, and it is also one of the powerful guarantee ways to promote the competitive level of all countries. The random matrix model algorithm has unique advantages to construct the team’s collective technical and tactical ability structure model. The quantitative relationship of the model describes the relationship between the technical and tactical ability structure and the result of victory and defeat and makes the advantages and disadvantages of the team clear, which is conducive to the subsequent targeted training and improvement. The technical and tactical abilities of the teams in different seasons were input to verify the prediction accuracy of the model for the teams in different seasons. In the face of the rapidly changing game situation, the coach team timely transmits the adjusted technical and tactical strategies to the players on the field and deals with the changes accurately and effectively. After the game, the opponent’s strengths and weaknesses should be clarified, and the team’s daily training details should be summarized to provide reference for the cultivation of collective technical and tactical consciousness. The random sample covariance matrix of the random monitoring matrix is constructed and the maximum and minimum eigenvalues of the sample covariance matrix are solved. The ratio of characteristic values is used to construct the detection index of characteristic values, and the detection threshold algorithm of characteristic values is determined to judge the competitive ability of volleyball players. In the case of false alarm rate and matrix size, based on Tracy-Widom distribution characteristics, the maximum eigenvalue and minimum eigenvalue approximations of sample covariance matrix are used to improve the eigenvalue index detection threshold algorithm, and the influence of false alarm rate, matrix size, and other parameters on the improved eigenvalue index detection threshold is further studied. Then, Iris data set was used to verify the effectiveness of the algorithm in terms of accuracy, recall rate, and comprehensive effective value, and the validation results proved that the accuracy of the algorithm reached more than 90%.

Sci-Tech Popularization (STP) and Sci-Tech Innovation (STI) are two significant components to realize China’s innovation development. STI provides direction and content for STP, while STP creates an intense atmosphere for STI. By establishing two evaluation index systems of STP and STI, the STP index and the STI index of China and Chinese 31 provinces from 2010 to 2019 was calculated, and the STP index and the STI index from 2020 to 2024 were predicted. Finally, the relative development degree (RDD), the coupling coordination degree (CCD) and the dynamic degree of STP and STI were figured out. The results showed that: (1) From 2010 to 2024, the STP index and the STI index of China and Chinese 31 provinces showed a growing trend. The growth rate of STI was higher than that of STP, but the STP and the STI were low. (2) The RDD results showed that the development of STP lagged behind that of STI after 2018, and the gap between them showed a growing trend. (3) The CCD of STP and STI in China spanned three grades: moderate imbalance, slight imbalance, and approaching imbalance. The CCD in Chinese each province spanned five grades: severe imbalance, moderate imbalance, slight imbalance, approaching imbalance, reluctant coordination. The CCD was developing in a good direction, China and most Chinese provinces were still in an unbalanced level instead. Finally, suggestions on infrastructure, technical means, personnel, and social responsibility were put forward to promote the coordinated development between STP and STI in China.

“…The objective assignment approach can be employed for the assignment when the evaluation demander wishes to reduce the subjective arbitrariness of the complete assessment outcomes. The pull-apart grading approach is used in this research to achieve objective indicator empowerment, which is one of the indicator empowerment methods [23]. This is its specific content:…”

In keeping with contemporary demands, the integration of political and ideological education with student management empowers students to actively embrace the establishment of a superior ideological culture in a more open and laid-back learning environment. The creation of an extensive index system enables the integration and collaboration of political and ideological instruction and student management duties in colleges and universities. The theory of system coupling is used to discuss the level of synergy and consistency of system development. The subjective empowerment method uses the FIAHP technique to determine the subjective weight of the standard. The objective weight of the indicator is determined by using the pull-out grade method. The LPE-SMW coupling coordination model is constructed by combining the weights of the two indexes to solve the weights. The coupling coordination level is evaluated and examined in order to confirm the efficacy of the coupling coordination model in examining the development and integration between political and ideological education and student management in colleges and universities. The coupling degree of coordination in the eastern region is approximately 0.65, and the degree of coupling coordination of the LPE-SMW in the central region has a mean yearly increase of 0.43% over the 20 years, according to the results of the smoothness test of each variable of the LPE-SMW linking coordination degree model, which shows differences at the 1% level. The linking coordination model offers a fresh approach to the creation of successful integration between political and ideological education and student management in higher education by offering a thorough examination of the relationship between the two.
