The varying rotational speed and forces are considered during the establishment of the model. Using Hamilton's principle, the partial differential governing equation of motion can be derived for the rotating shell. Based on the governing equation, Galerkin's approach is applied to obtain a two-degree-of-freedom nonlinear system. Numerical simulations are performed to investigate the nonlinear dynamic responses of the rotating shell. In summary, numerical studies show that the velocity and forces have effects on the time histories, phase portraits and power spectrum densities (PSD) of the response.","PeriodicalId":267944,"journal":{"name":"2017 International Conference on Computer Technology, Electronics and Communication (ICCTEC)","volume":"771 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116141555","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 particular, locationbased social networks (LBSNs) allow users to check in and share their travel tips with various smart devices anytime and anywhere, which could result in big data problems. On the one hand, it makes tourism data not only larger but also more difficult to store and manage. On the other hand, tourists have to spend a long time collecting information on points of interest (POIs) from the Internet and making customized trip schedules before traveling. To provide a more pleasant trip service, the paper proposes a cyber-physical system for touristcentric customized trip recommendation, named Trip-CPS based on cloud computing and big data technology. This system consists of a data-collection module for user-generated data (UGD) and contextual data, a data fusion and management module for multisource heterogeneous data storage, fusion and computing. And a recommendation module provides tourists with appropriate trips in suitable times and places. The techniques of cloud computing and big data can be used to enhance the performance of smart tourism, so tourists can enjoy various personalized trip recommendations","PeriodicalId":267944,"journal":{"name":"2017 International Conference on Computer Technology, Electronics and Communication (ICCTEC)","volume":"59 7 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115431358","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 plays an important role in pattern recognition. In the traditional BP Neural Network, the recognition accuracy rate will drop significantly while translating or rotating test images. However, when extracting the features of the original images as the input in which the neural network is most interested, the performance of the network is improved. This paper proposes two new methods of processing the original images and extracting the feature. One is to add a sliding window and translate appropriate units to center images. The other is to rotate the input image to align its axes to its principle directions. This is achieved by Principal Component Analysis(PCA) to the input image and find its principle directions. According to the experiment results, the problem as above has been solved, and the recognition accuracy rate has improved from 96.66% to 97.12%. It is proved that the methods are simple but effective.","PeriodicalId":267944,"journal":{"name":"2017 International Conference on Computer Technology, Electronics and Communication (ICCTEC)","volume":"16 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114646916","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 first introduces LoRa network architecture, focuses on its key technologies such as LoRaWAN, Adaptive Data Rate and Selective Working Modes. Then this paper further analyzes the packet format and characteristics of LoRa, mainly referring to three basic parameters: Code Rate (CR), Spreading Factor (SF) and Bandwidth (BW). After theoretical analysis of these factors, the influences of these factors on the transmission rate and packet duration are simulated. Finally, tests are taken to verify performance of LoRa such as delay and received signal intensity under three circumstances of open areas, residential quarters and parks.","PeriodicalId":267944,"journal":{"name":"2017 International Conference on Computer Technology, Electronics and Communication (ICCTEC)","volume":"71 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123535234","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}
