Furthermore, iterative Hilbert transform is used to improve the accuracy of frequency estimation for signals which do not satisfy Bedrosian theorem and Nuttall theorem, and the adaptability of the algorithm is improved. The simulation and experiment show that the improved algorithm reduces the distortion of the frequency conversion signal and has strong adaptability.","PeriodicalId":101777,"journal":{"name":"2020 International Conference on Communications, Information System and Computer Engineering (CISCE)","volume":"7 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126347765","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}

As the first country where the severity of the disease has been witnessed, China has been implementing some effective policies to prevent the spread of the infection. For example, all citizens, who come back to the community from other cities, other provinces, or other countries, have to be obligatorily isolated until they were affirmed to be uninfected. However, there was someone who concealed the travel experiences in the health survey, and they had infected many healthy people before testing positive for Coronavirus. Therefore, in this paper, an IoT system, which is composed of the wearable healthcare device, the smartphone, and the cloud servers, is described. It aims to give support for the management of communities to distinguish the people having close contact with the confirmed cases. Hence, basic health monitoring sensors are employed by the wearable device, and this device will be cheaper than the common wearable products, such as Mi Band or iWatch, because it only has the basic functions. Furthermore, the device can communicate with the smartphone of users via Bluetooth Low Energy to send messages about health conditions or receive simple commands. Moreover, through the techniques of the internet, the phone can convey the vital signals and the present locations of users, which are obtained by special locating systems, to the cloud server. The cloud server processes and records the data, and an application on the smartphone can provide the visualized results of cloud computing to users.","PeriodicalId":101777,"journal":{"name":"2020 International Conference on Communications, Information System and Computer Engineering (CISCE)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132104757","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 system supports multi-user attendance and face liveness detection at the same time. The system can automatically collect face data, which will be saved in the database as well as attendance results. The face detection part of the system is based on MTCNN (Multitask Convolutional Neural Network) algorithm, and the face recognition part is based on FaceNet algorithm. The algorithm implementation is based on TensorFlow framework, and the face liveness detection part is based on ERT (Ensemble of Regression Tree) algorithm, which can judge whether the user blinks. The attendance system is written in Python language, and the user interface is designed by Qt library. The experimental results show that the system achieves a good performance in real-time face recognition. The false accept rate and false rejection rate of face recognition are within 2%, and the recognition rate can be stable at 20 FPS.","PeriodicalId":101777,"journal":{"name":"2020 International Conference on Communications, Information System and Computer Engineering (CISCE)","volume":"435 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133192182","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}
