数字化操控时代的艺术作品

本文分析了计算机界面是如何组成和构造审美经验的,其出发点是本雅明的《机械复制时代的艺术作品》。文章先从细部讨论本雅明的膜拜价值和展示价值的观念,而后把数据库作为范式模型,勾勒出创建计算机对象的基本操作,最后解释为什么说数据库从本体论上把以展示价值为特征的现代艺术作品转变为以操控价值为特征的后现代艺术作品。

关于构建现代农业数字化水网的探讨

淮安市位于京杭运河与古淮河交汇处,水资源丰富,水网密布,农业生活用水富足,是名副其实的鱼米之乡。但是随着城市的扩张和人口的增长,加之农业水资源调配混乱,农业用水压力越来越大,用水时节农民到处找水的事情时有发生。

钢管数字化预精焊技术装备发展现状

从油气输送用焊管预精焊技术原理入手,详细介绍了某公司在预精焊工艺中的典型关键技术(高效预焊技术和优质多弧精焊技术)及数字化预精焊装备等方面取得的系列突破,并介绍了相关技术和装备在典型工程中的实际应用情况。与传统“一步法”焊接工艺相比,采用预精焊工艺及其装备后,焊缝冲击韧性高、离散度小;焊缝成形美观、表面光洁,且过渡平缓;焊缝一次合格率、产品成材率、产能都有提高;节约电能17%左右。

Prioritizing Alarms in Real-Time： Intelligent Alarms Advanced System

During the operation of complex process, such as oil production or refming, abnormal situations may occur, leading to an alarm flooding. Alarm flooding is the signalling of a large number of alarms in a few minutes, in such a way that it is impossible for the operator to attend to all alarms. On these occasions, it is usual that the operator leaves the alarm summary list and gets an analysis of the plant through the screens of the DCS （digital control system）, seeking to understand the situation. The alarm summary list ceases to be a useful tool. In such cases, the operator might have the aid of a filter that would present the highest priority alarms and other information associated with them, enabling him to gain a better knowledge of the situation. This paper describes the interface of a system aimed to help the operator to have a more comprehensive knowledge of the process （a better situational awareness） during process upsets that cause alarm flooding, recovering the utility of the alarm layer to the safety of industrial processes.
