The current IPv6 network has fewer reliable landmarks with limited accuracy, while the IPv4 network already has a large number of reliable landmarks. If IPv4 landmarks can be used in IPv6 landmark mining, the accuracy and efficiency of IPv6 landmark acquisition will be improved. To this end, this paper proposes an IPv6 landmark mining method based on domain name screening and IPv4-IPv6 connection. This method first uses the domain names of government agencies, top universities, and top websites as seed domain names, and continuously obtains a large number of domain names through web crawlers; then performs DNS resolution on the obtained domain names to obtain their corresponding IPv4 address and IPv6 address; and finally evaluate and analyze whether the two addresses are located in the same location, and determine whether to use it as an IPv6 landmark. This method successfully associates the IPv4 geolocation with the IPv6 geolocation, and uses the IPv4 landmarks to obtain and evaluate the IPv6 landmarks. Experimental results show that this method can obtain city-level IPv6 network landmarks more efficiently, and it also has a certain ability in street-level landmark mining.","PeriodicalId":191106,"journal":{"name":"Proceedings of the 2021 5th International Conference on Electronic Information Technology and Computer Engineering","volume":"30 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-10-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133598051","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}

Aiming at the problem that the amplitude of angular velocity and angular acceleration of 3-5-3 hybrid polynomial interpolation algorithm is too high, a 3-3-5 hybrid polynomial interpolation trajectory planning method is proposed. Firstly, the D-H (Denavit-Hartenberg) model of the rail inspection robot is used to compute its kinematics equation. Secondly, according to the constraints of motion curve (angle, angular velocity, angular acceleration continuous), kinematics constraints are obtained and interpolation points are determined. Thirdly, the coefficient expression of the hybrid polynomial interpolation algorithm is solved by substituting kinematics constraints and interpolation points into the formula of the 3-3-5 hybrid polynomial interpolation algorithm. Finally, the 3-3-5 hybrid polynomial interpolation algorithm is simulated in MATLAB. The results show that the 3-3-5 hybrid polynomial interpolation algorithm can effectively reduce the amplitude of the angular velocity and angular acceleration, reduce the jerk of the motor, and improve the overall motion performance of the inspection robot.","PeriodicalId":191106,"journal":{"name":"Proceedings of the 2021 5th International Conference on Electronic Information Technology and Computer Engineering","volume":"45 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-10-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127652089","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}

Because the vibration of equipment or components is its main operation index and determines its operation stability and service life, it is of great engineering significance to monitor and analyze its vibration degree. This paper introduces a vibration signal detection technology based on MEMS acceleration sensor. Firstly, the single-chip microcomputer STM32F103C8T6 is used as the main controller, and then the multi range MMA7361 acceleration sensor is used as the measurement sensor of vibration signal. When the acceleration vibration is more intense, the corresponding acceleration is also large and the change frequency is very fast. At this time, the singlechip microcomputer ADC is used to collect the output value of the sensor. After collecting multiple groups of data, it is analyzed in time domain and frequency domain, Separate the waveforms of each frequency band, and then send them to the host computer in LoRa communication mode for further analysis and processing. Through the detection test of each frequency band signal of 1g vibration frequency, the maximum error of acceleration value is no more than 5%, and the frequency error is no more than 1%. It shows that the system can effectively detect the change of vibration signal and facilitate the accurate troubleshooting of equipment faults.","PeriodicalId":191106,"journal":{"name":"Proceedings of the 2021 5th International Conference on Electronic Information Technology and Computer Engineering","volume":"39 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-10-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124591142","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, people in the environment with the same sound pressure level have different subjective feelings. To find a new evaluation method of high-speed railway environmental noise, it's proposed to describe the subjective feelings of the people affected by it from the psychoacoustic. In this research, this article collects high-speed railway environmental noise samples on a certain section of the Xiang-Gui route and calculates the corresponding psychoacoustic parameters based on the Zwicker model. It is found that the high-speed railway environmental noise with similar psychoacoustic annoyance will cause different auditory perceptions, and the correlation between psychoacoustic parameters and the signal characteristics of noise is generally low. In a word, Zwicker psychoacoustic annoyance model can't fully describe the auditory perception of the people affected by the highspeed railways environmental noise, which means that there are still some limitations of the model. Therefore, exploring the unique perceptual factors of the human ear for the noise in the high-speed railway and integrate it into Zwicker psychoacoustic annoyance model will become the main research direction in the next stage.","PeriodicalId":191106,"journal":{"name":"Proceedings of the 2021 5th International Conference on Electronic Information Technology and Computer Engineering","volume":"34 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-10-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114437087","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}

Although the existing works using graph neural network have been fruitful, they still face the following three challenges: (1) insufficient capture of user's fine-grained preferences at aspect level; (2) unable to capture the unique multi-modal distribution of user and friend aspect-level preferences; (3) lack the ability to weigh the importance of aspect information adaptively. To fill this gap, we propose a social recommendation model called AMMSR based on adversarial multi-modal viewpoint capturing. In order to achieve fine-grained modeling, AMMSR firstly projects candidate item into multiple latent aspect spaces to realize one-to-one query of user preferences at aspect level. Secondly, the adversarial variational bayes technique is introduced to capture the multi-modal preferences of users and their friends in latent aspects. Finally, two self-attention modules are set up on the user end and the commodity end to achieve the purpose of personalized information fusion. Extensive experiments on three public datasets show that AMMSR is generally superior to the existing methods, and several visual case studies verify that our model can effectively capture multi-modal viewpoints.","PeriodicalId":191106,"journal":{"name":"Proceedings of the 2021 5th International Conference on Electronic Information Technology and Computer Engineering","volume":"65 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-10-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"117286888","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}
