L’Éducation sentimentale, roman des masses by Sylvie Triaire

“…En partant d’une analyse du lexique désignant le peuple, qui révèle une égalisation des termes et un refus d’investir axiologiquement tel terme plus qu’un autre (notamment celui de « peuple »), l’article s’attache à montrer la poétique des masses à l’œuvre dans ce roman de la césure historique de 48, poétique qui accompagne une réflexion politique sur les masses, montrées en Février 48, dérobées puis liquidées en Juin 48, afin de laisser place à la société de masse (reposant sur la production, la consommation de masse, la voie / voix plébiscitaire).…”

Public opinion model based on super-influencer integrating network community and content by Jianliang WEI, Hao JI, Tengyan TIAN, Shengli ZHOU

“…Aiming at the abnormal deviation and distortion of online public opinion,a public opinion model based on super-influencer integrating network community and content was designed.Deffuant-Weisbuch (DW) model was adopted,and factors such as user relationship,node identity and information noise were incorporated into the model,and the generation of public opinion deviation was simulated through simulation experiments.The results indicate that super-influencer leads to irreversible deviation of network public opinion,controversial content causes opinion fluctuation and convergence,but not the final opinion as a whole.There are differences in the interference effect between strong and weak communities,and by increasing the internal strength and external influence of the community,it can conduct public opinion confrontation with super-influencer,thus reversing the direction of public opinion deviation.…”

Distributed dynamic mapping scheme based on cost function by Guo-dong GE, Yun-fei GUO, Ju-long LAN, Cai-xia LIU

“…For supporting efficient host mobility and mapping identifiers onto locators,a distributed dynamic mobility mapping scheme based on cost function was proposed.In the scheme,depending on the mobility pattern and communication feature,the communication of mobile node is divided into three communication models,namely,moving update model,balanced transmission model and resolving query model.In order to minimize the total resolving cost,three mapping approach are proposed based on distributed multicast,consistent hash functions and proactive sharing respectively in the mobile domain.For each mapping approach,corresponding registration update,resolution query and packet delivery strategies are designed.Simulation results show that the scheme can achieve the minimum resolving cost,and can have low resolve latency and good adaptability for network topology dynamic changing.…”

An energy-efficient multi-channel MAC protocol for linear sensor network by Fei TONG, Rucong SUI, Yu CHEN, Heng SU, Hengrui LIU, Shangfeng SU, Yuke YAN

“…Sensor nodes in linear sensor network (LSN) are deployed linearly due to the linear topology of the monitoring area.Most of the state-of-the-art medium access control (MAC) protocols designed for LSN adopted the duty-cycling and pipelined-forwarding (DCPF) schemes.They can reduce data propagation delay and network energy consumption but may still cause issues such as transmission competition, interference, and energy hole.To address these issues, an improved DCPF MAC protocol was proposed based on multiple channels and redundant-node deployment for LSN.The extensive simulations based on OPNET demonstrate that, compared with existing protocols, the proposed protocol shows a better performance in terms of energy efficiency, packet delivery ratio, throughput, and packet transmission latency.…”

Pedestrian surveillance system based on mobile vehicle by Huijun XING, Shuo CHANG

“…Pedestrian surveillance is one of the most important aspects in the surveillance system.Traditional surveillance equipment can only cover the limit area.Namely,once the surveillance equipment is implemented,it can only monitor a specific region.Besides,the surveillance system can't detect if there is a person in the surveillance picture or not.The professional staffs are needed to determine whether there is a person in the surveillance picture.To solve this problem,a computer vision based on mobile pedestrian surveillance system was designed.By implementing a surveillance camera on a mobile small vehicle and remotely control it,the system could switch the monitoring area.Besides,the system could classify and locate the pedestrian in the picture with the deep convolutional neural network and correlation filters.Finally,the system was tested on the spot,which verified the feasibility of the system.…”
