1Multi-agent Control of High Redundancy Actuation显示文摘The high redundancy actuator(HRA)concept is a novel approach to fault tolerant actuation that uses a high number of small actuation elements,assembled in series and parallel in order to form a single actuator which has intrinsic fault tolerance.Whilst this structure afords resilience under passive control methods alone,active control approaches are likely to provide higher levels of performance.A multiple-model control scheme for an HRA applied through the framework of multi-agent control is presented here.The application of this approach to a 10×10 HRA is discussed and consideration of reconfguration delays and fault detection errors are made.The example shows that multi-agent control can provide tangible performance improvements and increase fault tolerance in comparison to a passive fault tolerant approach.Reconfguration delays are shown to be tolerable,and a strategy for handling false fault detections is detailed.Jessica Davies Roger Dixon Roger M.Goodall Thomas Stefen 2014International Journal of Automation and computing2014,11,1:2
2基于学习负荷调查之教与学的探讨显示文摘学习负荷调查是用于测定学生为了完成课业和学业任务所花费全部相关学习时间的工具。除了使用定量分析工具(问卷调查、学习负荷应用程序),还可以使用定性分析方法(学习日记、学习负荷曲线)。目前对学习负荷的研究表明,仅仅单纯测量学习时间对改进专业的办学质量几乎不能提供任何实质性依据。因此,教师和学生应在客观数据的基础上,认识到学习负荷这一主题对构建和规划专业以及影响学生能力发展的重要性。此外,学习负荷调查工具在单纯的统计学习时间功能以外还具有其他潜力。Claudia Gómez Tutor Stefen Müller 陈颖(翻译) 2019应用型高等教育研究2019,4,3:2
