    État actionnaire et capitalisme de connivence au Maroc : le cas de la Caisse de dépôt et de gestion (CDG) by Mohamed Oubenal, Abdellatif Zeroual

    Published 2021-07-01
    “…Despite the resurgence of developmental aspirations with the Moroccanization policy in the 1970s, the CDG was quickly captured by Moroccan crony capitalism embedded in a hierarchical global economic system. It suffered from the privatizations of the 1990s for the benefit of companies related to the holders of political power.In the 2000s, the organization and strategy of the CDG changed to comply with the constraints/injunctions of a shareholder logic. …”

    Communication service priority in smart substation and its queue scheduling method by Jun’e LI, Qiuyu LU, Jian LIU, Kai YUAN, Wei TIAN, Bijun PENG

    Published 2021-07-01
    “…The future development of power grid puts forward the requirement of unified network for all the communication services in smart substation.In order to meet the different quality of service (QoS) requirements of various communication services, as well as ensure the real-time and reliability of key services when the network congestion occurs, a priority scheme and its queue scheduling method for the smart substation was proposed.The priorities of the communication services in the smart substation were assigned considering the delay requirements, the importance to power grid operation control, and the traffic of the communication services.The queue scheduling algorithm of hierarchical deficit weighted round robin (HDWRR), combining the advantages of strict priority queue (SPQ) algorithm and deficit weight round robin (DWRR) algorithm, was designed for the proposed priority scheme.The simulation results show that the proposed method has isolation ability for malicious traffic, and can ensure the real-time and reliable transmission of key services in smart substation once the network is congested.…”

    Multi-view graph neural network for fraud detection algorithm by Zhuo CHEN, Miao ZHU, Junwei DU

    Published 2022-11-01
    “…Aiming at the problem that in the field of fraud detection, imbalance labels and lack of necessary connections between fraud nodes, resulting in fraud detection tasks not conforming to the hypothesis of homogeneity of graph neural networks, multi-view graph neural network for fraud detection (MGFD) algorithm was proposed.First, A structure-independent encoder was used to encode the attributes of nodes in the network to learn the difference between the fraud node and the normal node.The hierarchical attention mechanism was designed to integrate the multi-view information in the network, and made full use of the interaction information between different perspectives in the network to model the nodes on the basis of learning differences.Then, based on the data imbalance ratio sampled subgraph, the sample was constructed according to the connection characteristics of fraud nodes for classification, which solved the problem of imbalance sample labels.Finally, the prediction label was used to identify whether a node is fraudulent.Experiments on real-world datasets have shown that the MGFD algorithm outperforms the comparison method in the field of graph-based fraud detection.…”

    Improving energy efficiency and network performance in IaaS cloud with virtual machine placement by Jian-kang DONG, Hong-bo WANG, Yang-yang LI, Shi-duan CHENG

    Published 2014-01-01
    “…The existing virtual machine(VM) placement schemes mostly reduce energy consumption by optimizing utilization of physical server or network element.However,the aggressive consolidation of these resources may lead to network performance degradation.In view of this,a VM placement scheme was proposed to achieve two objectives.One is to minimize the number of activating physical machines and network elements to reduce the energy consumption,and the other is to minimize the maximum link utilization to improve the network performance.This scheme is able to reduce the energy consumption caused by physical servers and network equipment while optimizing the network performance,making a trade off between energy efficiency and network performance.A novel two-stage heuristic algorithm for a solution was designed.Firstly,the hierarchical clustering algorithm based on minimum cut and best fit algorithm was used to optimize energy efficiency,and then,local search algorithm was used to minimize the maximum link utilization.The simulations show that this solution achieves good results.…”

    Two-layer grouped Byzantine fault tolerance algorithm for UAV swarm by Yu CHEN, Lianxing JIA

    Published 2022-01-01
    “…To reduce the communication complexity and improve the robustness of blockchain network, a two-layer grouped Byzantine fault tolerance algorithm for unmanned ariel vehicle (UAV) swarm was proposed.First, nodes were divided into several groups according to the formation results of UAV swarm.A portion of high-reputation nodes were selected from each group to form a committee, and other nodes were used as shared nodes.Threshold signature techniques were employed to reduce communication complexity.In that way, nodes from other groups only needed to communicate with the committee nodes of the current group, thus greatly reducing the average communication delay.In addition, the hierarchical structure, which made the identity of the primary node hidden in the committee, reduced the risk of being adaptively attacked by the Byzantine nodes and improves the robustness of the system.Experimental results demonstrates that the proposed algorithm significantly reduces the delay of the consensus process and can effectively ensure the aliveness of the system compared with the comparison algorithm.…”

    Research on low-energy-consumption deployment of emergency UAV network for integrated communication-navigating-sensing by Li WANG, Qing WEI, Lianming XU, Yuan SHEN, Ping ZHANG, Aiguo FEI

    Published 2022-07-01
    “…In public emergencies such as accident relief, rescue workers are faced with challenges, such as poor communication, unstable navigating, and inaccurate disaster sensing.It is necessary to deploy an emergency unmanned aerial vehicle (UAV) network to guarantee the services of communication-navigating-sensing.Aiming at alleviating the problem of limited energy of UAV, a low-energy-consumption deployment of an emergency UAV network was first proposed for integrated communication-navigating-sensing (ICNS).The proposed scheme was able to realize network topology reconstruction and role cognition on demand.Then, a particle swarm algorithm based hierarchical matching decision-making algorithm was presented to jointly optimize three sub-problems, including the associations between UAVs and users, the resource allocation for multi-role UAV communications, and the UAV position.Simulation results show that the proposed ICNS scheme can achieve flexible adaptation of the multi-objective requirements and limited network resources, and dramatically reduce the demand for the number of UAVs and the deployment energy consumption.…”
