However, the detection performance of the existing unsupervised sensing methods is usually far below that of supervised sensing methods. In order to overcome this problem, we propose an iterative unsupervised learning based cooperative spectrum sensing (CSS) algorithm, where the concept of iteration is introduced to improve detection performance. Specifically, in each iteration, i) The CSS technology is first used to make global labels by combining the local labels of the individual detectors constructed in the last iteration; ii) And then, individual detectors are constructed by utilizing supervised learning to fit the mapping from local sample set to the current global labels. During above iterative process, the global labels contribute to improving individual detectors, while these improved individual detectors can cooperatively make more accurate global labels, which will be utilized in next iteration. Finally, with the increase of the number of iterations, these individual detectors can be used to online cooperatively detect spectrum status when there are only slight changes in global labels. Simulation results show that the proposed algorithm can achieve comparable individual and cooperative detection performance with the existing supervised sensing methods over a wide signal-to-noise ratio (SNR) region.","PeriodicalId":178054,"journal":{"name":"2020 5th International Conference on Information Science, Computer Technology and Transportation (ISCTT)","volume":"108 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128487058","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}

Starting from the population factors of the number of floating population, population density, natural population growth rate, and urbanization rate, this paper collects panel data of traffic accidents of China from 2004 to 2018, and estimates the parameters using fixed effect model. Time effect variables are added based on traditional panel data, and a fixed-effect model is constructed to study the impact of road traffic accident deaths in China. The results show that from 2004 to 2018, China's population density and the number of deaths from road traffic accidents change in the opposite direction. The natural population growth rate and urbanization rate have positive changes with the death toll from road traffic accidents respectively. Therefore, this paper proposes appropriate preventive measures from traffic congestion, floating population management, traffic safety management, and other aspects to reduce road traffic accidents and property losses caused by demographic changes.","PeriodicalId":178054,"journal":{"name":"2020 5th International Conference on Information Science, Computer Technology and Transportation (ISCTT)","volume":"37 5","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114130667","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 effectively prevent the management and technical risks faced by the domain name system, there is an urgent need to obtain relatively complete Internet domain name data to provide basic data support. However, due to a series of restrictive factors such as non-enumerable domain name space, scattered domain name data storage, and restricted access to registry resources, the acquisition of Internet domain name data has become a challenge. We propose a domain name acquisition method based on zone transfer: the authoritative DNS master name server and slave name server usually maintain the function of the entire domain based on the same zone file. We try to find every authoritative domain name server that provides domain name services. The zone transfer obtains the domain name data information of the corresponding domain. We explored the way to implement the method and conducted experimental evaluation. The method has shortcomings in terms of effectiveness and ability, but a considerable amount of domain name data can be obtained to support the construction of a mapping database between global domain names and IP addresses.","PeriodicalId":178054,"journal":{"name":"2020 5th International Conference on Information Science, Computer Technology and Transportation (ISCTT)","volume":"85 1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114231896","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}

Therefore, it is necessary to accurately identify the corresponding emotional tendencies of different aspects. Concerning the problem that the traditional neural network model cannot accurately construct the text aspect feature and sentiment feature information, an aspect sentiment analysis model based on the LSTM-GateCNN network is proposed. Textual contextual semantic information is modeled through the LSTM network fused with attention mechanism to obtain deep semantic information, combined with the gated convolutional neural network to simultaneously model the textual and emotional information, and finally, text sentiment classification is performed at the softmax function layer. Experiments on the AI Challenger Chinese dataset have verified the effectiveness of the model, which has a further improvement in accuracy compared with the previous method.","PeriodicalId":178054,"journal":{"name":"2020 5th International Conference on Information Science, Computer Technology and Transportation (ISCTT)","volume":"89 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127229783","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}

However, it may potentially play a role in facilitating pandemic spread when encountering SARS-CoV-2. Mainly focusing on the role of rail traffic, this research constructs a 2-layer China rail network topological model based on collected China rail data, identifying 3 dynamic transmission scenarios. Then introduces the rail mobility rate into the traditional dynamic transmission model in epidemiology to fit the model for rail transportation. Finally, taking SARS-CoV-2 as an example, the transmission dynamics of sars-cov-2 is studied by simulation experiments, and the orbital movement rate control in different scenarios is measured as one of the potential interventions. Experiment outcomes lead to some managerial insights that (1) with an initial outbreak on the core layer, a faster response is required, while with an eruption on the periphery layer, more appropriate reactions and interventions are encouraged. (2) Adjusting the rail mobility rate of periphery transmission can be used to delay the local outbreak of SARS-CoV-2 in previously unaffected regions.","PeriodicalId":178054,"journal":{"name":"2020 5th International Conference on Information Science, Computer Technology and Transportation (ISCTT)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126047801","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 very important to set the safety threshold of pier settlement reasonably and accurately. In this paper, the dynamic model of high-speed maglev train/track interaction system is established. The total response of track beam is divided into static response caused by pier settlement and dynamic response caused by vibration of elastically beam, so a track beam model composed of dynamic displacement model and static displacement model is established. The dynamic performance of the train/track coupling system is evaluated under the conditions of different settlement values and number of settlement piers, and the safety threshold of pier settlement is analyzed from the perspective of passenger comfort and running stability of the train. The results show that the safety threshold of pier settlement is about 16mm for the maglev train with a speed of 400km/h.","PeriodicalId":178054,"journal":{"name":"2020 5th International Conference on Information Science, Computer Technology and Transportation (ISCTT)","volume":"38 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126774515","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}
