Time series and semantics-based chinese microblog topic detection and tracking method by Tie-ming CHEN, Xiao-hao WANG, Wei-wei PANG, Jie JIANG

“…As a widely used tool in social networks,microblog is definitely with short document,quick broadcasting and topic changeable,which results in big challenging for social topic detection and tracking.A new systematic framework for micro-blog topic detection and tracking was proposed based on the microblog clustering using temporal trend and semantic similarity.Firstly,a feature words selection method for hot topics was presented by defining the temporal frequent words set.Secondly,an initially clustering was conducted depending on the selected temporal frequent words set.As far as the overlaps between initial clusters concerned,an effective overlap elimination algorithm was proposed,by introducing the extended short document semantic membership,to separate any possible overlapped initial clusters.Finally,an aggregated topic clustering method was employed using the cluster semantic similarity matrix.The experiments were at last done on some real-world dataset from Sina microblog.It show that the method for chinese microblog topic detection and tracking can obtain excellent performance and results.…”

Set reconciliation based on counting Bloom filters by Xiao-mei TIAN, Da-fang ZHANG, Kun XIE, Can HU, Xiao-bo YANG, Chang-qiong SHI

“…A new set reconciliation algorithm was presented,which called counting-Bloom-filter based set reconciliation(CBFSR).This method represented sets S_A and S_B as counting Bloom filters,subtracts S_A's counting Bloom filter from S_B's counting Bloom filter,the differences denoted CBF(S_B)−CBF(S_A),then determined S_B−S_A elements in S_B with CBF(S_B)−CBF(S_A),and finally performed union operation on S_B−S_A and S_A.Simulation resdts show counting-Bloom-filter based set reconciliation combines the advantages of exact set reconciliation and approximate set reconciliation,besides gaining all S_B−S_A elements with single-round messgage exchanges,it can apply to update-intensive distributed systems because counting Bloom filters support element deletion operation.…”

Dynamic Contact Analysis of Torus-involute Gear by Fang Meijuan, Liu Lei

“…Taking the torus-involute gear as study object,according to the theory of gear meshing and the gear hobbing process,the tooth surface equations of torus-involute gears with convex and concave teeth are derived by using the tooth surface equation of counterpart rack.According to the mathematical conditions of neither undercutting nor tooth pointing,based on MATLAB,the Graphical User Interface which contains geometric parameter designs of torus-involute gear is developed.In the light of the tooth surface equations of torus-involute gear,the three-dimensional coordinates of torus-involute gear are calculated which can be used to develop the3-D solid models.The Hypermesh is used to mesh the 3-D models of torus-involute gear.Based on the nonlinear contact algorithm,the finite element models of convex and concave torus-involute gears meshing are established which can be used to implement the dynamic contact analysis in ABAQUS.The results reveal that the width of torus-involute gears is limited by gear undercutting or tooth pointing and the maximum contact stress will be steady after hobbing for a while.The contact stress is small when just a pair of gear teeth are meshing,while the contact stress is large when two pairs of gear teeth are meshing.…”

Federated learning-based user access strategy and energy consumption optimization in cell-free massive MIMO network by Yuanyuan YAO, Yiqiu LIU, Sai HUANG, Chunyu PAN, Xuehua LI, Xin YUAN

“…To solve the problem that how users choose access points in cell-free massive multiple-input multiple-output (CF-mMIMO) network, a prioritized access strategy for poorer users based on channel coefficient ranking was proposed.First, users were evaluated and ranked for their channel quality and stability after channel sensing, and suitable access points were selected in sequence according to the order of the channel state information.Second, considering issues such as users' energy consumption and data security, a federal learning framework was used to enhance user's data privacy and security.Meanwhile, an alternating optimization variables algorithm based on energy consumption optimization was proposed to optimize the multi-dimensional variables, for the purpose of minimizing the total energy consumption of the system.Simulation results show that compared with the traditional user-centric in massive MIMO, the proposed access strategy can improve the average uplink reachable rate of users by 20%, and the uplink rate of users with poor channels can be double improved; in terms of energy consumption optimization, the total energy consumption can be reduced by much more than 50% after optimization.…”
