简介:“学习资源”是E-learning在线学习系统中的面向用户的教学认知核心,是普通用户度量在线学习系统应用体系的现实反映。通过合理的资源交互设计,可满足E-learning在线学习系统对于普通用户的学习效果评估,为策划系列线上、线下结合教学任务提供了可靠的运营知识体系。文章就基于校企合作的E-learning高职教学平台中学习资源的交互设计进行研究,为高职院校、企业、教师(培训师)探索高职教育向网络技术化、校企合作化、学习终身化提供帮助。

简介:以便完成聪明的车辆的侧面的控制,基于云模型使用双性人认知的模型并且遮蔽推理,解决决定问题聪明的车辆的侧面的控制质、量。由驾驶车辆获得很多个实验数据,根据数据的概念分类数据并且修理云控制器的输入和输出变量,设计聪明的车辆的云控制器的控制规则,并且遮蔽并且修理云控制器的参数:期望,熵和亢奋的熵。以便验证云控制器的有效性,联合模拟站台基于Matlab/Simulink/CarSim被建立。试验性的分析显示出那:司机侧面的控制器基于云模型能完成需要的角度追踪,并且完成好控制效果,它也验证那一系列心理活动象感到那样,认知,计算,决定等等模糊、不明确。
