    L’éducation populaire et coopérative à l’épreuve du philosopher by Sylvain Connac

    Published 2012-01-01
    “…The study, pressed also on conversations with specialists and teachers, allows to raise some fears as for a possible decline of the introduction of the DVP in a cooperative pedagogy context. The know-how acquired by the teachers in cooperative class contributes to better manage the devices of the DVP, even if a priori more than a year is necessary for all the pupils to benefit from it. …”

    Optimal relay selection scheme and outage probability analysis in cooperative wireless networks by Youhong FENG, Zhi YANG, Xuxing DING, Xuefeng YUE, Qiqi LI, Xiaojuan Xie

    Published 2018-11-01
    “…Optimal relay selection can effectively improve the system performance in the communication network with cooperative relays from the view of physical layer security.The optimal relay selection schemes for relay transmission system with multiple single-antenna eavesdroppers were investigated,and the differences between the amplify-and-forward (AF) protocol and the decode-and-forward (DF) protocol were we discussed and compared separately.For comparison,the direct transmission without relay was also discussed.The theoretical analysis and simulation results show that the optimal relay selection scheme can effectively guarantee the security of the system.…”

    A feature selection method based on instance learning and cooperative subset search by Xiaoyuan XU, Li HUANG

    Published 2017-06-01
    “…Feature subset selection is a key problem in such data mining classification tasks.In practice,the filter methods ignore the correlations between genes which are prevalent in gene expression data,additionally,existing methods are not specially conceived to handle the small sample size of the data which is one of the main causes of feature selection instability.In order to deal with these issues,a new hybrid,filter wrapper was proposed,and a cooperative subset search(CSS),was then researched with a classifier algorithm to represent an evaluation system of wrappers.The method was experimentally tested and compared with state-of-the-art algorithms based on several high-dimension allow sample size cancer data sets.Results show that the proposed approach outperforms other methods in terms of accuracy and stability of the selected subset.…”

    Research on the cooperative offloading strategy of sensory data based on delay and energy constraints by Peiyan YUAN, Saike SHAO, Ran WEI, Junna ZHANG, Xiaoyan ZHAO

    Published 2023-03-01
    “…The edge offloading of the internet of things (IoT) sensing data was investigated.Multiple edge servers cooperatively offload all or part of the sensing data initially sent to the cloud center, which protects data privacy and improves user experience.In the process of cooperative offloading, the transmission of the sensing data and the information exchange among edge servers will consume system resources, resulting in the cost of cooperation.How to maximize the offloading ratio of the sensing data while maintaining a low collaboration cost is a challenging problem.A joint optimization problem of sensing data offload ratio and cooperative scale satisfying the constraints of network delay and system energy consumption was formulated.Subsequently, a distributed alternating direction method of multipliers (ADMM) via constraint projection and variable splitting was proposed to solve the problem.Finally, simulation experiments were carried out on MATLAB.Numerical results show that the proposed method improved the network delay and energy consumption compared to the fairness cooperation algorithm (FCA), the distributed optimization algorithm (DOA), and multi-subtasks-to-multi-servers offloading scheme (MTMS) algorithm.…”
