    The teaching of the association between physical inactivity and non-communicable diseases in physical education classes by Julia Terra, Lúcio Canabarro, Marilda Neutzling, Nicole Gonzales, Airton Rombaldi

    Published 2015-09-01
    “… The study was conducted with physical education teachers from elementary and high schools in the urban area of Pelotas, southern Brazil, and identified the prevalence of those who taught the association of physical inactivity (PI) with non-communicable diseases (NCDs) during their classes. In addition, the moment when the content was discussed in the class and the length of time used for that purpose were investigated. …”

    Digital twin-assisted multi-mode communication resource management methods for smart buildings by Cheng SHI, Pengju LIU, Zhigang DU, Sunxuan ZHANG, Zhenyu ZHOU, Huifeng BAI, Guoqing HE, Wenwen SUN, Yue MA

    Published 2023-01-01
    “…The multi-mode communication network provides communication support for the collection, transmission, and processing of energy regulation data and the training of energy regulation models for smart buildings.Digital twin can provide state estimation of computing resources and channel characteristics, assist in the multi-mode communication resource optimization management, and improve the training precision of energy regulation models.However, the digital twin-assisted multi-mode communication resource management of smart buildings still face challenges such as large training error of energy regulation model, coupling of multi-timescale resource allocation, and contradictions between training precision improvement of energy regulation model and energy consumption optimization.Aiming at the above challenges, a multi-timescale communication resource management optimization algorithm based on digital twin and empirical matching learning was proposed.The weighted sum of global model loss function and energy consumption was minimized by jointly optimizing the large-timescale gateway selection and small-timescale channel allocation and power control.Simulation results show that the proposed algorithm can improve the performance of weighted sum of global model loss function and energy consumption, ensure the precise energy regulation requirement and promote the low-carbon operation of smart buildings.…”

    Secure D2D underlaying cellular communication based on artificial noise assisted by Xiao-lei KANG, Xin-sheng JI, Kai-zhi HUANG

    Published 2015-10-01
    “…A secure communication scheme based on artificial noise assisted from base station(BS)was proposed to improve the system secrecy rate of the D2D underlaying cellular.Firstly,the system secrecy rate was modeled.Then the BS with multi-antennas added artificial noise(AN)in cellular user’s signal as well as designed beam vectors of the desired signal and artificial noise to maximize system secrecy rate.In the end,a joint optimization scheme based on the fairness constraint was introduced to optimize beam vectors of the desired signal,the power allocation for BS’s information signal and AN and the D2D power control.Simulation results show that the system ergodic secrecy rate can be improved 2.7 bit·s<sup>−1</sup>·Hz<sup>−1</sup>more than the schemes based on SVD and zero-forcing at most.…”
