Abstract

Traditional physical calligraphy education faces huge challenges and opportunities in the context of the rapid development of big data technology and the Internet. This paper first combines big data technology and the educational objectives of calligraphy and proposes the use of machine learning to solve traditional calligraphy education challenges and lead the internal development of aesthetic education in schools. Then it elaborates the research idea and structural framework of machine learning, which mainly consists of two parts: global features of the GIST algorithm and local features of SIFT algorithm, and optimizes machine learning by weighted self-learning hash high-dimensional data indexing algorithm. Finally, the study was conducted to determine the target and content of the study based on the selection of evaluation features and to use machine learning to analyze the satisfaction of calligraphy education on the decentralized Internet. A satisfaction analysis was conducted. The results showed that for students: the satisfaction value of decentralized Internet-based calligraphy education fell within the range of 35.01% to 42.98%, and its average satisfaction was 38.99%, with students outperforming parents and teachers with 38.99% average satisfaction. This study will help students to learn calligraphy systematically with half the effort so that the calligraphy culture can take root in their minds and blossom again, which is the true meaning of “learning for the past”.

Abstract

Anion‐derived solid‐electrolyte interphase (SEI) has received growing attention owing to its appealing properties like fast ion transport and excellent passivation effect. However, a sophisticated understanding of anion‐derived SEI is lacking. To common wisdom, anion‐derived SEI features an inorganic‐rich composition. Herein, it is reveal that the freshly formed anion‐derived SEI consists of a polymer‐rich outer layer and an inorganic inner layer. Then, the organic components dissolve during the discharge process, while the inorganic species with low solubility are retained in the empty SEI husk. The accumulation of empty SEI husks during cycling forms a reacted lithium (Li) layer, which features a much higher content of anion‐derived inorganic species than the newly formed SEI. Therefore, the acknowledged "anion‐derived inorganic‐rich SEI" actually refers to the reacted Li layer instead of the freshly formed SEI. This work provides fruitful insights on the compositional features of anion‐derived SEI. [ABSTRACT FROM AUTHOR]

25. The Study of University Students' Self-Concept

Author

Zhang, Xiaofeng and Li, Chengzong

Abstract

Objective: Discussed the development of self-concept of university students. Methods: Used "Tennessee Self Concept Scale (TSCS)", measured 426 university student's self-concept status. Results: In the dimension of physical self-ethics, self-criticism, self-satisfaction, there were gender differences in university students' self-concept. Males' physical-self, self-criticism and self-satisfied were higher than females', while females' ethics were higher than males'. When referred to social self-concept, there were special differences. Students majored liberal arts had a higher score than the students of science. There were also differences in self-criticism, for example, the home location, whether only child or not, and the grades. College students also had differences in grade. Conclusion: College students' self-concept developed to a relatively stable level in the university. Except for a noticeable difference in gender, only a certain dimensions were noticeable in other demographic variables, while self-criticism had remarkable differences in most of them.

30. Supervisory Control of Discrete Event Systems With Dynamic Control Specifications by Petri Nets

Author

Li, Chengzong, Chen, Yufeng, and Li, Zhiwu

Abstract

Supervisory control can enforce a desired control specification for discrete event systems (DESs). If the specification of a system is changed over time, i.e., the system is subject to dynamic control specifications, control reconfiguration methods are proposed to implement the new specification. However, the existing reconfiguration methods require redesigning and adding controllers for the new specification. In this article, we propose a dynamic control policy for a Petri net model with dynamic control specifications. First, a fully functional supervisor is designed for the net model, which is dynamically optimal since it can dynamically adjust control actions for the net model and prevent all illegal markings, while all legal markings are permitted for each specification. Then, by the dynamically optimal supervisor, the dynamic control policy consists of two steps: 1) guide the system from the current illegal state to a marking that satisfies the new specification and 2) switch control actions of the supervisor. By using the proposed method, the system can satisfy the dynamically changeable specifications. Finally, some examples are used to illustrate the proposed method.

Abstract

This paper proposes a deadlock prevention policy for flexible manufacturing systems (FMSs) based on a think-globally-act-locally approach and a structurally minimal method. First, by using the think-globally-act-locally approach, a global idle place is temporarily added to a Petri net model with deadlocks. Then, at each iteration, an integer linear programming problem is formulated to design a minimal number of maximally permissive control places. Therefore, a supervisor with a low structural complexity is obtained since the number of control places is greatly compressed. Finally, by adding the designed supervisor, the resulting net model is optimally or near-optimally controlled. Three examples from the literature are used to illustrate the proposed method.

Abstract

Zhihao Zhao, Fengyun Zhang, Ruicong Ma, Lin Bo, Zeqing Zhang, Chaoqun Zhang, Zhirong Wang, Chengzong Li, Yu Yang Department of Cardiology, The Affiliated Hospital of Xuzhou Medical University, Xuzhou, People’s Republic of ChinaCorrespondence: Yu Yang, Tel +86-15651359875, Email xuzhouyangyu@163.comPurpose: This study aimed to develop and validate a risk nomogram model for predicting the risk of atrial fibrillation recurrence after radiofrequency catheter ablation.Patients and Methods: A retrospective observational study was conducted using data from 485 patients with atrial fibrillation who underwent the first radiofrequency ablation in our hospital from January 2018 to June 2021. All patients were randomized into training cohort (70%; n=340) and validation cohort (30%; n=145). Univariate and multivariate logistic regression analyses were used to identify independent risk factors. The predictive nomogram model was established by using R software. The nomogram was developed and evaluated based on differentiation, calibration, and clinical efficacy by concordance statistic (C-statistic), calibration plots, and decision curve analysis (DCA), respectively.Results: The nomogram was established by four variables including left atrial diameter (OR 1.057, 95% CI 1.010– 1.107, P=0.018), left ventricular ejection fraction (OR 0.943, 95% CI 0.905– 0.982, P=0.005), type of atrial fibrillation (OR 2.164, 95% CI: 1.262– 3.714), and systemic inflammation score (OR 1.905, 95% CI 1.408– 2.577). The C-statistic of the nomogram was 0.741 (95% CI: 0.689– 0.794) in the training cohort and 0.750 (95% CI: 0.670– 0.831) in the validation cohort. The calibration plots showed good agreement between the predictions and observations in the training and validation cohorts. Decision curve analysis and clinical impact curves indicated the clinical utility of the predictive nomogram.Conclusion: The nomogram model has good discrimination and accuracy, which can screen high-risk groups
