元电网MetaGrid:基于平行电网的新一代智能电网的体系与架构

open access: yes智能科学与技术学报, 2021
随着新能源设备的大规模接入,大电网系统的脆弱性、开放性和不确定性显著上升,系统的管理与控制面临重大的挑战。构建基于平行系统与元宇宙思想的平行电网系统,形成虚实融合的智能大电网管理与控制理论方法,是解决上述问题的一种可行途径。介绍平行电网系统MetaGrid的基本体系架构,在此基础上分析平行电网系统的关键技术,并展望平行电网潜在的应用场景。基于300节点热稳案例,提供一个平行电网应用案例的原型。期望通过构建平行电网系统,对实际电网系统进行精准建模,借助大规模的计算实验和虚实闭环的平行执行 ...

一种高效鲁棒的元宇宙环境下的多场景智能医疗模型研究

open access: yes大数据
现今医疗行业普遍存在医疗资源和教育资源不均衡、医疗体系智能化水平低、手术操作依赖个体经验等问题,拥有沉浸、互动特点的元宇宙为以上问题提供了解决方案。但现有的解决方案多基于虚拟现实或人工智能中的一种技术,针对特定的手术或疾病诊断问题进行探索,少有针对多功能、多场景应用的医疗元宇宙进行的系统研究。基于此,提出了元宇宙环境下的多场景智能医疗模型框架(MetaMed),从接入层、数据层、技术层、应用层自底向上阐述了模型的框架设计。该框架在智能手术、线上会诊、医疗培训 ...

The Chinese metaverse: An analysis of China's policy agenda for extended reality (XR)

open access: yesPolicy &Internet, Volume 17, Issue 1, March 2025.
Abstract This paper explores China's strategic embrace of extended reality (XR) technologies within its digital economy policy framework. Through a content analysis of 45 Chinese government documents, we show how China has positioned XR—which encompasses augmented reality (AR), virtual reality (VR) and mixed reality (MR)—within the nation's innovation ...
