ECG monitoring network is a special kind of wireless body area network based on IEEE802.15.4 communication protocol. To study the communication technology of ECG monitoring network is of great importance. The communication mechanism and data frame structure are analyzed, and the node energy efficiency model and transmission delay model are established; A unselfish cooperative game algorithm combined with light and low profit operator is proposed to overcome the conflict between energy consumption and time delay and realize the balance between them. Experiments showed that the proposed algorithm could effectively reach equilibrium of the two targets. Moreover, compared with Multi-objective Evolutionary Algorithm and Evolutionary cooperative game Algorithm, it had better performance in convergence speed and global convergence.","PeriodicalId":355388,"journal":{"name":"Proceedings of the 2022 International Conference on Computational Infrastructure and Urban Planning","volume":"223 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-06-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121283576","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

It was created to improve generation process and efficiency of industrial products at first. Today, digital twins start to create scenarios of smart cities with information technology and computing. This paper explores the digital twin implementation in design progress of transportation network. A case study of Wellington Digital Twin has been analyzed. This public and accessible model allows for communities and neighborhoods’ participation in transportation network design progress with components to tag and report comments in urban areas. It is found that compared with conventional transportation simulation, the digital twins have the characteristics of accurate, implemented, and digitalized. Meanwhile, digital twins have the capability to present the exact counterpart of physical world and predict how it perform in the future. This research also argues that digital twins are not a panacea although they can assist interactive transportation network simulation to a certain extent.","PeriodicalId":355388,"journal":{"name":"Proceedings of the 2022 International Conference on Computational Infrastructure and Urban Planning","volume":"32 7 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-06-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125737971","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This paper integrated four subsystems of SHELL model and five dimensions of traditional SERVQUAL scale. An airline service quality evaluation system based on the improved SERVQUAL model was established. Considering that the index evaluation is subjective and difficult to quantify, the possibility degree ranking was used to figure out the comprehensive weight of indexes. Finally, five Chinese carriers were empirically analyzed to verify the rationality and feasibility of the evaluation system. The results show that staff affects passenger satisfaction from many aspects, and that assurance, empathy and tangibility have great impacts on service quality. Carriers generally score low in flexibility of customer choice and attention to different people, which are key directions of airline service improvement. Based on above analysis, two suggestions are put forward: improving employees’ subjective initiative and meeting passengers’ diversified needs. The model can be applied to the service quality evaluation of other carriers.","PeriodicalId":355388,"journal":{"name":"Proceedings of the 2022 International Conference on Computational Infrastructure and Urban Planning","volume":"56 6 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-06-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116182299","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The beam-column joint under complex stress should be fully considered especially during its repair design. Steel plate hoop reinforcing RC column-steel beam joint is not only able to retrofit the column structural ability but also to address the beam-column connection problem easily through the steel connection measures. Based on a realistic engineering case, this paper presents the finite element analysis on steel plate hoop reinforcing RC beam-column joint subjected to complex loadings, which provides the technical suggestions for the engineers. In the finite element model, applied loads calculated from Chinese design software PKPM are suitably addressed and different working scenarios are discussed including the changed heights of reinforced rib (75mm and 150mm), the vertical support to the cantilever steel beam and different loading combinations of loads from column, surrounding beams, edge beam and the eccentric load from stairs. The results show that the joint with short reinforced rib of 75 mm shows stress concentration with the stress exceeding design strength so that local reinforcement should be considered. The joint with 150 mm reinforced rib under combined loads from edge beam and eccentric loading from stairs also shows local stress exceeding design material strength. Local reinforcement measures are proposed to improve the joint structural capability. The vertical support to the cantilever steel beam can improve the joint stress and deformation situations. During repair construction, the vertical propping should be loaded incrementally and maintained at 40 kN.","PeriodicalId":355388,"journal":{"name":"Proceedings of the 2022 International Conference on Computational Infrastructure and Urban Planning","volume":"15 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-06-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114613625","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

It is a data-fusion method and the data is mainly divided into three parts: satellite data, track data and the satellite-receiver data. In this paper, we use two odometers equipped with GNSS receivers as ground systems and a section of the Hong Kong Tun Ma Line is selected as the trajectory of the track for simulation. First, the carrier phase double difference method and Melbourne-Wübbena (MW) algorithm are applied to solve the integer ambiguity. Then, combing the data of track's tangent and the data received from satellite, the least squares estimation is applied to achieve position correction as well as odometer correction. Finally, the presented method is verified through a series of simulations. The experimental results show that the satellite-track data fusion algorithm can achieve certain accuracy to continuously correct the accumulated errors, which also provide a good continuous monitoring of the length of the train. The proposed method is expected to provide a low-cost, high-precision tool for train's integrity monitoring.","PeriodicalId":355388,"journal":{"name":"Proceedings of the 2022 International Conference on Computational Infrastructure and Urban Planning","volume":"19 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-06-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122335507","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In order to accurately predict the flow of passengers, this paper uses Space Syntax and Artificial Neural Network (ANN) to construct the evaluation model of tourism road congestion. The model makes use of the characteristics of objective and dynamic assignment of ANN to train and estimate each scenic spot weight. The accessibility analysis of Space Syntax is used to understand the connections between roads; then it uses the mathematical model to effectively combine them, so that the model has the ability to estimate road congestion when the street network structure, scenic spots distribution and crowd flows are inconsistent. The empirical results show that: (I) The areas with high scenic spots attractiveness of Kulangsu are mainly distributed on the edge of the island; (II) The model can predict the problem of unreasonable distribution of roads. The results can be used as the basis for future tourism space management.","PeriodicalId":355388,"journal":{"name":"Proceedings of the 2022 International Conference on Computational Infrastructure and Urban Planning","volume":"49 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-06-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124254868","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
