下一代公共安全视频监控系统的大数据分析

视频监控因其可以提供丰富的、直观的以及精确的信息而成为主要的监控工具. 然而, 随着视频监控系统在世界各地的大规模建设, 由于一些诸如“有用信息和线索不能及时从视频大数据中被发现”的问题, 降低了犯罪预测和公共安全治理的检测效率. 各类公共安全信息系统被用于交通事故治理、犯罪事件和恐怖事件的预测. 但是, 大规模的系统冗余建设导致了“IT 资源”和“信息过载”的巨大浪费. 为了解决上述问题, 如大数据、云计算和虚拟化技术已被广泛应用于公共安全行业. 采用“前+后”的模式, 为下一代公安系统提出了一种新的架构.在该架构下, 介绍了云计算技术如分布式存储和计算、巨大的异构数据的检索, 并且提出了多个优化策略, 提高了资源的利用率和任务的完成效率.

数字孪生驱动的大数据制造服务模式

 大数据、数字孪生等新技术引发了人们对制造模式的新思考，结合《中国制造2025》中制造业服务化重要内容，提出一种数字孪生驱动的大数据制造服务新模式。从智能制造与数字孪生、制造服务模式方面综述了国内外相关研究进展；提出了一个数字孪生驱动的大数据制造模式开放式体系架构及其运作逻辑；从数字孪生驱动的2个世界及其描述、数字孪生与大数据的结合、大数据制造服务模式中模型建立与优化3个方面对大数据制造服务模式使能技术进行了研究。该制造服务模式对促进中国传统制造企业转型升级和提升新国际竞争环境下综合竞争力具有理论和现实意义。     

Big data management in the mining industry

The mining industry faces a number of challenges that promote the adoption of new technologies. Big data, which is driven by the accelerating progress of information and communication technology, is one of the promising technologies that can reshape the entire mining landscape. Despite numerous attempts to apply big data in the mining industry, fundamental problems of big data, especially big data management(BDM), in the mining industry persist. This paper aims to fill the gap by presenting the basics of BDM. This work provides a brief introduction to big data and BDM, and it discusses the challenges encountered by the mining industry to indicate the necessity of implementing big data. It also summarizes data sources in the mining industry and presents the potential benefits of big data to the mining industry. This work also envisions a future in which a global database project is established and big data is used together with other technologies(i.e., automation), supported by government policies and following international standards. This paper also outlines the precautions for the utilization of BDM in the mining industry.
