Construction Technology of Roof Membrane for World Cup Main Stadium

Based on the installation of the roof membrane of Lusail Stadium which is the main stadium of Qatar World Cup in 2022, a series of key technical challenges in the design and construction of the roof PTFE membrane of large stadiums are studied. Based on the analysis of the roof cable net system, the study formulated the overall sequence of membrane installation, and defined the construction method of membrane lifting and unfolding. Focusing on membrane fixing techniques with the tension rings, compression rings, and horizontal cable nodes, it also optimized membrane connection methods with arch and horizontal cable, and provided waterproof construction methods. According to the findings, the construction of stadium roof membranes should follow a logical sequence. The membranes’ fixing, connection and waterproof construction will have an important impact on the final quality.

A Study of Sports Hospitality at the Rugby World Cup 2019 for a Tourism Experience Product: A Consideration from the Viewpoint of Eliminating Overtourism in Spectator Sports

In this research project,we focus on sports hospitality at the Rugby World Cup 2019 as a practical example of the qualitative pursuit of sports tourism in the Japanese tourism industry.STH Japan K.K.,Japan’s first company specializing in sports hospitality,hosted the first mega sports event held in Japan.A similar spectator service will next be implemented at the Tokyo Olympics and Paralympics.Sports hospitality is a new way to enjoy watching sports by adding a meal and entertainment before and after the match to the event ticket.Positioning and using sports hospitality as a tourism experience product,we can use qualitatively designed creative and effective methods that professional human resources could provide to tourists.This research project provides an overview of tourism experience products,looks at their economic effects at the Rugby World Cup 2019,and the sales results of the sports hospitality at the event.I conducted an observation survey at the Rugby World Cup 2019 Scotland vs.Samoa match held at Misaki Park Stadium(Kobe,Hyogo)on September 30,2019 focusing only on tourism products in that framework.I also conducted a qualitative survey on March 18,2020 in a semi-structured interview format with STH Japan K.K.senior advisors.The research results revealed the possibility of eliminating overtourism in spectator sports and the lack of sports hospitality spaces in Japan.Usually,when watching a sports match where many spectators gather,the uniform start and end times cause crowding and overtourism.The conventional challenge has been to create tourism products that reduce congestion and provide an enjoyable tourism experience.Sports hospitality is effective for relieving the stress caused by overtourism in spectator sports.In order to solve the shortage of sports hospitality spaces,one issue to consider is the deregulation by the government.

France Scoreless, Out in World Cup

1998年7月13日凌晨进行的第16届世界杯足球赛的冠亚军决赛中,疯狂的法国“蓝队”以排山倒海之势,雷霆万钧之力碾碎了巴西人的卫冕之梦。3:0的结局不仅使法国队在这场世纪末的绿茵大战中脱颖而出,成为世界杯历史上崭新的第7支冠军队,而且捍卫了欧洲足球的荣誉,使欧美两强打成了“世界平手”,在全部16届世界杯赛争斗中,夺魁次数各占8次。 法国的国鸟是公鸡。公鸡的天性是好斗。面对强大的巴西队,肩负着6000万法国人对胜利的渴望,好斗善斗的法国队毫无惧色,不怕重压。比赛进行到第26分钟时,10号齐达内高高跃起,干净利落的把球顶进了网窝。第45分钟,法国队又得角球,人丛当中,又是前卫齐达内门前抢点,攻其不备,再施冷箭,头球攻门,皮球出其不意,从巴西队6号卡洛斯双腿之间穿过,飞入球门,梅开二度。 此刻的巴黎的大街小巷,每一个广场都灌入了满满的疯狂的巴黎人。数不清的三色旗在远眺飞扬。最最火爆的是凯旋门和它面前笔直的香榭里舍大道。这里象是火山口喷泻出来的火红岩浆,缓缓的向协和广场流去,辐射出热和光,燃红了巴黎的夜空。人们说,世界杯,煮沸了法兰西。 朋友,以上文字见《科技英语学习》1998年第8期之36页。然而,4年后的今日,从日本本州岛东南岸港市横滨传来了以下消息。下文称: When they arrive

A NETWORK ANALYSIS OF THE 2010 FIFA WORLD CUP CHAMPION TEAM PLAY

This paper analyzes the network of passes among the players of the Spanish team during the last FIFA World Cup 2010,where they emerged as the champion,with the objective of explaining the results obtained from the behavior at the complex network level.The team is considered a network with players as nodes and passes as(directed) edges.A temporal analysis of the resulting passes network is also done,looking at the number of passes,length of the chain of passes,and to network measures such as player centrality and clustering coefficient.Results of the last three matches(the decisive ones) indicate that the clustering coefficient of the pass network remains high,indicating the elaborate style of the Spanish team.The effectiveness of the opposing team in negating the Spanish game is reflected in the change of several network measures over time,most importantly in drops of the clustering coefficient and passing length/speed,as well as in their being able in removing the most talented players from the central positions of the network.Spain's ability to restore their combinative game and move the focus of the game to offensive positions and talented players is shown to tilt the balance in favor of the Spanish team.

EXTRACTING BEHAVIOURAL MODELS FROM 2010FIFA WORLD CUP

The FIFA World Cup^(TM) is the most profitable worldwide event.The FIFA publishes global statistics of this competition which provide global data about the players and teams during the competition.This work is focused on the extraction of behavioural patterns for both,players and teams strategies,through the automated analysis of this dataset.The knowledge and models extracted in this work could be applied to soccer leagues or even it could be oriented to sport betting.However,the main contribution is related to the study on several automatic knowledge extraction techniques,such as clustering methods,and how these techniques can be used to obtain useful behavioural models from a global statistics dataset.The information provided by the clustering algorithms shows similar properties which have been combined to define the models,making the human interpretation of these statistics easier.Finally,the most successful teams strategies have been analysed and compared.

2023年FIBA世界杯中国男篮攻防能力分析

采用文献资料法、录像分析法、比较分析法与数理统计法对中国男篮参加2023年FIBA世界杯的5场比赛进行详细的技术统计与高阶数据分析,总结中国男篮在国际赛场上的不足与差距,寻找本次杯赛中国男篮失利的原因并提出改进建议,旨在为今后优化开展中国男篮的选材、训练与比赛等工作提供理论依据。结果表明:中国男篮得分能力弱,得分方式匮乏且战术素养较低;篮板球争抢能力较差,队员缺乏拼搏精神;队员难以适应国际大赛强度;防守缺乏针对性与压迫性;球员不适应国际比赛吹罚尺度;阵容缺乏平衡性,年轻队员发挥不稳定。为此中国男篮应加强外线投射能力,提高技战术素养;强化队员争抢篮板球的意识与能力;提高球员抗压能力与球队整体防守能力;重视年轻队员的培养,促进年轻球员向核心球员的转变;此外,国内联赛应增强对抗强度,提高并推进国内裁判员执法理念、尺度与国际接轨。

2023橄榄球世界杯南非跳羚队比赛分析

2023年橄榄球世界杯在法国举办,南非跳羚队成功卫冕冠军。该文运用文献资料法、录像观察法和数理统计法等研究方法,对南非跳羚队在2023橄榄球世界杯中的比赛数据进行统计与分析。研究结果有以下3点。(1)南非跳羚队成功卫冕橄榄球世界杯冠军,成为历史上首个“四冠王”球队。(2)替补席强大,南非跳羚队拥有深厚的前锋储备,个别球员甚至可胜任两个位置,并且球员的身体素质水平高,在集团对抗方面有较大优势。(3)射门状态较稳定,有时比赛双方都很难直接达阵得分,需要借助踢球去得分;扑搂成功率不稳定,南非跳羚队风格强悍,身体对抗能力强,但此次世界杯扑搂成功率最高为84%,最低为71%,防守能力起伏不定。

2023年国际篮联篮球世界杯归化球员攻防综合实力等级评价研究

本文运用文献资料法、录像观察法、TOPSIS法、秩和比法和数理统计法,探讨2023年国际篮联篮球世界杯归化球员的攻防技术特点,评价各归化球员的攻防指标,并结合模糊集理论进行综合评价分析中国首位归化球员与其他归化球员的差异。结果显示:归化球员在攻防能力上存在显著差异,其中乔丹卡里克·琼斯·克拉克森、卡里克·琼斯、约什·霍金森和朗戴·霍利斯·杰弗森表现突出;李凯尔在防守端表现良好,但进攻端对中国队帮助有限。为此,建议:中国男篮优化归化球员选择策略,综合考虑如技战术水平、比赛经验、适应能力和文化背景等多方面因素,并增加归化球员数量,同时加强本土球员培养,以期提高整体竞技水平和国际竞争力。
