Because there are messages that have completed initial scheduling in the network, scheduling conflicts may occur in incremental scheduling of newly added backup nodes, resulting in failure of solution. In order to solve this problem, this paper proposes a step-by-step incremental scheduling backtracking algorithm based on impact factor. If the incremental scheduling does not find a feasible solution, the strategy of step-by-step backtracking is adopted. According to the size of the impact factor, the messages on the non fault nodes and the message incremental scheduling planning is carried out together with the existing messages to be scheduled.","PeriodicalId":266384,"journal":{"name":"2020 2nd International Conference on Advances in Computer Technology, Information Science and Communications (CTISC)","volume":"75 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133210848","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}

A compact planar monopole antenna with size 18.4×32.4×1.6mm3 is proposed for terminals of portable UWB mobile systems. The wider impedance matching characteristic of proposed antenna is obtained by adjusting antenna structure based on transmission line model theory. The new resonant frequency points are added by transforming rectangular radiation patch and CPW feeder of original antenna. Finally experimental results show the working bandwidth of proposed antenna is from 2.72GHz to 14.2GHz, which extends six times more than original antenna.","PeriodicalId":266384,"journal":{"name":"2020 2nd International Conference on Advances in Computer Technology, Information Science and Communications (CTISC)","volume":"211 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116524637","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}

Yet many challenges remain in modern LiDAR 3D point clouds processing algorithms. One is ground segmentation due to the real-time requirement dealing with huge input data from LiDAR. In this study, we propose a method to separate ground points from a point cloud in a hybrid way by adopting dynamic section division, height-based conditional filter, and multi-lines linear regression. Where, physical characteristics of LiDAR mounted on a vehicle have been introduced in the dynamic section division. Thereafter, we raise a conditional filter algorithm for filtering outliers of point clouds, and use multi-lines linear regression to generate the ground skeleton. In the end, the qualitative and quantitative experiments validate the performance by using two datasets and indicate that our proposed method outperforms state-of-the-art methods on KITTI in terms of accuracy 94.1% and runtime 432ms.

In this paper, the theoretical residual SI power in multi-tap analog SI cancellation with arbitrary time delay arrangement for each tap is derived, and the cancellation performance with fixed and optimal adjustable delay arrangement are compared by simulations. The influence of the bandwidth, the carrier frequency, the number of taps and the maximum delay of the SI channel on the cancellation performance are investigated. In consideration of the complexity of the optimal method, a novel algorithm for adjustable delay arrangement is proposed based on the cross-correlation of the reference signal and the SI signal.","PeriodicalId":266384,"journal":{"name":"2020 2nd International Conference on Advances in Computer Technology, Information Science and Communications (CTISC)","volume":"20 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125327816","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 resulting feature vectors are constructed in a sequence and used as input data for SVR. Finally, SVR is used for index prediction, and compare with convolutional neural network model and support vector regression model.
