The given paper discusses an intuitionistic fuzzy discrete time-space optimization model while taking into account the COVID-19 pandemic. The novelty of this study is characterized by the proposal of a distinctive multi-objective intuitionistic fuzzy transportation model in which the demand function varies with time as the number of infected, exposed and susceptible persons increase. Forecasting of demand is executed using the epidemic diffusion model. Also, a new approach to defuzzify triangular intuitionistic fuzzy numbers, depending upon the concept of the golden ratio, is presented. Intuitionistic fuzzy programming approach is used to obtain the pareto-optimal solution. A real-life numerical illustration is explained using the proposed methodology to examine its practical suitability. Outperforming the existing traditional method of solving a transportation problem verifies its proficiency.
本文讨论了一种考虑COVID-19大流行的直觉模糊离散时空优化模型。本研究的新颖之处在于提出了一个独特的多目标直觉模糊运输模型,其中需求函数随着感染、暴露和易感人数的增加而随时间变化。利用疫情扩散模型对需求进行预测。同时,基于黄金分割的概念,提出了一种三角直觉模糊数去模糊化的新方法。采用直觉模糊规划方法求解pareto最优解。一个现实生活中的数值说明解释使用提出的方法,以检查其实际适用性。通过超越现有的求解交通问题的传统方法,验证了该方法的有效性。

Sports exercise is very important for both physical and mental health, but improper exercise or equipment use may cause some security challenges. To address this issue, facing Internet of Things (IoT), currently, some video recognition algorithm-based smart security monitoring systems have been designed. However, existing video recognition algorithms usually assume that the data comes from the same collection device or follows the same distribution, resulting in ineffective handling of cross-camera or cross-device recognition problems. In this vein, this paper designed a transfer learning-based smart exercise monitoring security protection system, and proposed a new transfer learning-based video recognition framework, which consists of backbone network module, style transfer module, video feature aggregation module three parts and using this framework, two different models can be trained based on video face recognition dataset and video action recognition dataset, respectively, for identity recognition and action recognition. Experimental results show that the proposed framework can effectively handle video face recognition and video action recognition problems, which also demonstrates that our designed smart exercise monitoring security protection system can meet actual task requirements.
体育锻炼对身心健康都非常重要,但不适当的运动或设备使用可能会带来一些安全挑战。为了解决这一问题,面对物联网(IoT),目前已经设计了一些基于视频识别算法的智能安防监控系统。然而,现有的视频识别算法通常假设数据来自同一采集设备或遵循相同的分布,导致无法有效处理跨摄像头或跨设备的识别问题。为此,本文设计了一种基于迁移学习的智能运动监控安防系统,并提出了一种新的基于迁移学习的视频识别框架,该框架由骨干网络模块、风格迁移模块、视频特征聚合模块三部分组成,利用该框架可以分别基于视频人脸识别数据集和视频动作识别数据集训练两种不同的模型,用于身份识别和动作识别。实验结果表明,所提出的框架能够有效地处理视频人脸识别和视频动作识别问题,也证明了所设计的智能运动监控安防系统能够满足实际任务需求。

Vibration transmissibility at male and female wrist of the human hand-arm system and modeling 人体手臂系统男女腕部振动传递率及建模

The determination of standard values of vibration transmissibility at the wrist of the human body is very important to understanding vibration exposure and developing a valid model. In this work, the effects of human weight, gender, and other factors on the transmissibility of hand–arm vibration and vibration transmissibility in the [Formula: see text]-axis direction at the wrist site were randomly collected from 200 subjects (154 males and 46 females) as per the requirement of the standard ISO 10819. Moreover, the envelopes of the maximum and minimum values, as well as the mean and standard deviation of the vibration transmissibility at the wrist site, were obtained for both genders. Second, the effect of gender differences on the mean value of vibration transmissibility was analyzed. Finally, two three-degree-of-freedom (3-DOF) models of the hand–arm system were developed based on the average values of vibration transmissibility at the wrists of male and female subjects, respectively. The study revealed that the mean value of vibration transmissibility was greater in males than in females in the frequency range of 14–39 Hz. For the rest of the frequency ranges of females, their mean vibration transmissibility is greater than that of males, especially in the range 17–30 Hz. It was also observed that the vibration transmissibility of females is 10–18.5% smaller than that of males. The vibration transmissibility of females is greater than that of males by 40–83% when the frequencies are between 150 Hz and 250 Hz. The novelty of this proposed model is the prediction of model differences between males and females compared to other models that do so without considering gender differences. It is validated that the proposed modified model can be used to predict the vibration transmissibility of the wrist.
人体腕部振动传递率标准值的确定对于理解振动暴露和建立有效的模型具有重要意义。本研究按照ISO 10819标准的要求,随机抽取200名受试者(男性154人,女性46人),研究人体体重、性别等因素对手臂振动传递率和手腕部位[公式:见文]-轴方向振动传递率的影响。此外,还得到了两种性别腕部振动传递率的最大值和最小值以及平均值和标准差的包络。其次,分析了性别差异对振动传递率均值的影响。最后,分别基于男性和女性受试者手腕处的振动传递率平均值,建立了两个三自由度(3-DOF)的手臂系统模型。研究发现,在14 ~ 39hz的频率范围内,男性的振动传递率均值大于女性。在其余频率范围内,女性的平均振动传递率大于男性,特别是在17-30 Hz范围内。雌虫的振动传递率比雄虫小10 ~ 18.5%。在150 ~ 250 Hz频率范围内,雌性的振动传递率比雄性高40 ~ 83%。与其他不考虑性别差异的模型相比,该模型的新颖之处在于预测了男性和女性之间的模型差异。实验结果表明,该改进模型可用于腕部振动传递率的预测。
