    Spatio-temporal pattern detection in spatio-temporal graphs

    Use case of invasive team sports and urban road traffic

    Kamaldeep Singh Oberoi1, Géraldine Del Mondo2

    Revue Internationale de Géomatique, Vol.31, No.2, pp. 377-399, 2022, DOI:10.3166/RIG.31.377-399 c 2022

    Abstract Spatio-temporal (ST) graphs have been used in many application domains to model evolving ST phenomenon. Such models represent the underlying structure of the phenomenon in terms of its entities and different types of spatial interactions between them. The reason behind using graph-based models to represent ST phenomenon is due to the existing well-established graph analysis tools and algorithms which can be directly applied to analyze the phenomenon under consideration. In this paper, considering the use case of two distinct, highly dynamic phenomena - invasive team sports, with a focus on handball and urban road traffic,… More >

    Application of Depth Learning Algorithm in Automatic Processing and Analysis of Sports Images

    Kai Yang*

    Computer Systems Science and Engineering, Vol.47, No.1, pp. 317-332, 2023, DOI:10.32604/csse.2023.037266

    Abstract With the rapid development of sports, the number of sports images has increased dramatically. Intelligent and automatic processing and analysis of moving images are significant, which can not only facilitate users to quickly search and access moving images but also facilitate staff to store and manage moving image data and contribute to the intellectual development of the sports industry. In this paper, a method of table tennis identification and positioning based on a convolutional neural network is proposed, which solves the problem that the identification and positioning method based on color features and contour features More >

    SNG-TE: Sports News Generation with Text-Editing Model

    Qiang Xu*, Wei Zhang, Hui Ding, Shengwei Ji

    Intelligent Automation & Soft Computing, Vol.37, No.1, pp. 1067-1080, 2023, DOI:10.32604/iasc.2023.037599

    Abstract Currently, the amount of sports news is increasing, given the number of sports available. As a result, manually writing sports news requires high labor costs to achieve the intended efficiency. Therefore, it is necessary to develop the automatic generation of sports news. Most available news generation methods mainly rely on real-time commentary sentences, which have the following limitations: (1) unable to select suitable commentary sentences for news generation, and (2) the generated sports news could not accurately describe game events. Therefore, this study proposes a sports news generation with text-editing model (SNG-TE) is proposed to… More >

    A Study on the Improvement of Mental Health Status of Teachers’ Occupational Stress and Chronic Anxiety under Aerobic Exercise Alternative Activities

    Sanyou Yan1,*, Huaqing Yan2

    International Journal of Mental Health Promotion, Vol.25, No.2, pp. 249-263, 2023, DOI:10.32604/ijmhp.2023.023031

    Abstract The purpose of this study is to observe the occupational stress and chronic anxiety of college teachers and to carry out alternate activities of aerobic exercise to improve their mental health, the participants are 214 teachers from three universities in Yunnan Province, China. The results show that before the experiment, the overall situation of college teachers’ occupational stress and chronic anxiety is at a high level, while after the experiment, the occupational stress and chronic anxiety of college teachers are significantly relieved. In terms of gender, male teachers have higher occupational stress and chronic anxiety… More >

    A Research on the Air Permeability of High Polymer Materials Used to Produce Sports Clothing Fabrics

    Jike Gao1, Fawei Li2,*, Shangjun Liu1

    FDMP-Fluid Dynamics & Materials Processing, Vol.19, No.5, pp. 1173-1187, 2023, DOI:10.32604/fdmp.2022.021140

    Abstract Composite fabrics based on Polytetrafluoroethylene (PTFE) polymer displays several notable properties. They are waterproof, windproof, permeable to moisture and thermally insulating at the same time. In the present study, PTFE fibers are used as raw material to make fiber membranes. The film is formed by crisscrossing interconnected fiber filaments and the related air permeability: tensile creep characteristics and other properties are tested. The results show that the pore size, thickness, and porosity of the film itself can affect the moisture permeability of the film. The water pressure resistance of the selected fabric is 8.5 kPa, More >

    Influence of Nutritional Supplementation and Sports Training on the Physical Fitness of Track and Field Athletes

    Wenbing Zhu*

    Molecular & Cellular Biomechanics, Vol.19, No.2, pp. 89-96, 2022, DOI:10.32604/mcb.2022.018522

    Abstract This study aims to understand the influence of nutritional supplementation and sports training on the physical fitness of track and field athletes. Twenty track and field athletes from Chongqing Normal University were supplemented with nutrition and trained for eight weeks. Water, sugar, and vitamins were supplemented. They were trained three times a week, two hours each time. One hour was for special track and field training, and one hour was for physical training. Before and after the experiment, the body composition, sports quality, and functional movement screening (FMS) of the athletes were tested. Compared with More >

    An Enhanced Particle Swarm Optimization for ITC2021 Sports Timetabling

    Mutasem K. Alsmadi1,*, Ghaith M. Jaradat2, Malek Alzaqebah3, Ibrahim ALmarashdeh1, Fahad A. Alghamdi1, Rami Mustafa A. Mohammad4, Nahier Aldhafferi4, Abdullah Alqahtani4

    CMC-Computers, Materials & Continua, Vol.72, No.1, pp. 1995-2014, 2022, DOI:10.32604/cmc.2022.025077

    Abstract Timetabling problem is among the most difficult operational tasks and is an important step in raising industrial productivity, capability, and capacity. Such tasks are usually tackled using metaheuristics techniques that provide an intelligent way of suggesting solutions or decision-making. Swarm intelligence techniques including Particle Swarm Optimization (PSO) have proved to be effective examples. Different recent experiments showed that the PSO algorithm is reliable for timetabling in many applications such as educational and personnel timetabling, machine scheduling, etc. However, having an optimal solution is extremely challenging but having a sub-optimal solution using heuristics or metaheuristics is… More >

    Human Pose Estimation and Object Interaction for Sports Behaviour

    Ayesha Arif1, Yazeed Yasin Ghadi2, Mohammed Alarfaj3, Ahmad Jalal1, Shaharyar Kamal1, Dong-Seong Kim4,*

    CMC-Computers, Materials & Continua, Vol.72, No.1, pp. 1-18, 2022, DOI:10.32604/cmc.2022.023553

    Abstract In the new era of technology, daily human activities are becoming more challenging in terms of monitoring complex scenes and backgrounds. To understand the scenes and activities from human life logs, human-object interaction (HOI) is important in terms of visual relationship detection and human pose estimation. Activities understanding and interaction recognition between human and object along with the pose estimation and interaction modeling have been explained. Some existing algorithms and feature extraction procedures are complicated including accurate detection of rare human postures, occluded regions, and unsatisfactory detection of objects, especially small-sized objects. The existing HOI… More >

    Towards Prevention of Sportsmen Burnout: Formal Analysis of Sub-Optimal Tournament Scheduling

    Syed Rameez Naqvi1, Adnan Ahmad1, S. M. Riazul Islam2,*, Tallha Akram1, M. Abdullah-Al-Wadud3, Atif Alamri4

    CMC-Computers, Materials & Continua, Vol.70, No.1, pp. 1509-1526, 2022, DOI:10.32604/cmc.2022.019653

    Abstract Scheduling a sports tournament is a complex optimization problem, which requires a large number of hard constraints to satisfy. Despite the availability of several such constraints in the literature, there remains a gap since most of the new sports events pose their own unique set of requirements, and demand novel constraints. Specifically talking of the strictly time bound events, ensuring fairness between the different teams in terms of their rest days, traveling, and the number of successive games they play, becomes a difficult task to resolve, and demands attention. In this work, we present a… More >
