Computer-aided sports systems are an important area of current research. To be specific, it can combine computer vision, graphics, and motion capture technologies with the characteristics sports, design develop assisted according to user needs. As a result, is great practical importance application improve entertainment science learning, stimulate public participation in learn skills. Table tennis has very popular base China wide range audiences. However, for beginners or amateurs table tennis, difficult skills by relying on books, videos, etc., due lack professional technical guidance, which makes relatively them continuously their Sometimes they tend form wrong habits, not easy detect correct time, lead injuries over time. Therefore, instruction hindered development fitness certain extent. On other hand, course, learning techniques mostly dependent teacher’s explanation. Students bored repetitive boring teaching because need repeat exercises several times. The formation movements requires repeated from instructor address problems student’s movements. limited resources, teachers accommodate different students during process. In addition, team instructors, level proficiency varies, making make objective assessment. rapid modern technology field there urgent explore intelligent instructional support shortcomings traditional model. Motion recognition technology, as essential branch multimodal interaction been developing rapidly recent years. This research focus designing implementing system recognizing human based skeletal point pose information combining inertial sensors. collect data sensors located at main points body transmits host through multi-Bluetooth pairing transmission. After that, vector machines applied classify recognize general significant advantages movement classification distinctive tennis. both players video play role analysis tactical arrangement players. correction feature crucial significance value.

Influence of Consumption Decisions of Rural Residents in the Context of Rapid Urbanization: Evidence from Sichuan, China

Sustainability, Год журнала: 2023, Номер 15(23), С. 16524 - 16524

Опубликована: Дек. 4, 2023

Background: Promoting the transformation and upgrading of China’s rural consumer market is strategic significance for maintaining sustainable economic development in process urbanization. Research objects methods: Our objectives were to explore influencing factors residents’ consumption decision making provide reference formulating relevant policies. This study adopted questionnaire survey method collected 300 valid questionnaires. Through statistical analysis data multiple linear regression analysis, key affecting determined. Results: Education level, family income, view sociocultural are main residents. In addition, personal cognition attitude also important decisions. social influence has a certain positive impact on Conclusion: The external factors, including education level internal namely income concept. At same time, play an role purpose this objective suggestions improving expanding at policy so as promote China. decisions local stability was investigated. farmers’ can be understood by analyzing their tendency pattern.

Eco-Efficiency Measurement of Green Buildings and Its Spatial and Temporal Differences Based on a Three-Stage Superefficient SBM-DEA Model

Journal of Environmental and Public Health, Год журнала: 2022, Номер 2022(1)

Опубликована: Янв. 1, 2022

To explore the development of green building eco-efficiency in China, a three-stage superefficient SBM-DEA model was used to measure China based on interprovincial panel data from 2013-2020, and regional patterns evolutionary characteristics were analyzed time series spatial dimensions. It is found that overall level efficiency low, there are significant provincial differences, pattern gradient medium-medium-low area medium-medium gradually transitions shows agglomeration path dependence; among them, spillover diffusion effect high-efficiency areas significant, while low-efficiency generally maintain low growth, most have "Matthew effect," showing club convergence developed regions tend be H-H agglomerative, less L-L agglomerative. For this reason, local governance buildings should strengthened, cross-regional linkage mechanism established deepen technical cooperation division labor between regions.

Environmental Efficiency Evaluation of Construction Waste Generation Based on Data Envelopment Analysis and Malmquist Index

Buildings, Год журнала: 2022, Номер 12(8), С. 1189 - 1189

Опубликована: Авг. 8, 2022

The rapid development of urbanization in China recent years has resulted the production large amounts construction waste, which placed certain constraints on sustainable industry. This study measures environmental efficiency waste generated from static and dynamic perspectives using data envelopment analysis Malmquist index with 30 Chinese provinces during period 2011 to 2020. results showed that, a perspective, China’s generation been generally declining trend year by year, overall level is still not too high. At regional level, there stepwise decline eastern, central, northeastern, western regions. From point view, an average value 1.016, indicating that state improvement. highest east, eastern region developing well.

Today, English is the world’s main international language and widely spoken. In this context, learning of has long been valued by all countries. addition, plays an essential role in process economic globalization, specifically majority countries where not native language. At same time, as China’s integration into world grows, importance become more pronounced, demand for skills increased. present, ever-expanding opening to outside world, its developing science technology, rising status have created urgent need English-speaking professionals. This will lay foundation social development enable China play a greater active affairs, which great practical far-reaching historical significance. traditional teaching mode criticized due number issues. new standards change evaluation methods demands on methods. As result, with artificial intelligence application technology field education brought directions optimization classroom. diversified network technologies also provide support realization intelligent collaborative classroom teaching. To be specific, maturity speech synthesis enabled reach or even surpass level human teachers certain areas. However, limitations market environment methods, products that can focus are highly less collaborative. What more, stagnated compared other subjects. Obviously, from perspective integrating classroom, it quite necessary feasible design develop assistant applied college information continues evolve, both national teacher levels beginning how better used Therefore, use online presents opportunity research practice at university level.
