Dynamic modelling and robust current control of wind-turbine driven DFIG during external AC voltage dip

INTRODUCTION Due to concerns about emissions from fossil fuels and the depletion of fossil fuel resources, re- newable energy systems are becoming a topic of great interest and investment in the world. In particular, wind energy has been the subject of much recent research and development. In order to overcome the problems associated with fixed-speed wind-turbine system and to maximize the wind energy capture, many new wind farms will employ wind turbines based on Doubly-Fed Induction Ge…     

新制度经济学视角下民办高职院校产教融合建设组织模式探究——以河北省某民办高职院校为例

长期以来,产教融合存在着“壁炉现象”和“集体主义困境”,文章从新制度经济学的视角,运用产权理论和交易费用理论分析问题成因,从组织模式建设层面给出解决问题的办法。让“双主体”变为“单主体”,采用股份形式的集团化组织模式能够提高产教融合的效能,提高资源的有效配置,并通过案例实证进行了路径探究。     

"普通话水平测试"中的普通话语调刍议

人们对“普通话水平测试”中的普通话语调把握存在太多不确定因素。本文试图从阐述汉语声调变调的必然性和或然性出发，阐明声调与语调之间的复杂关系。声调与语调同时并存，两者的关系是音阶叠加的“代数和”，而不是“调形叠加”的“代数和”。声调受语调调节，语调通过声调得以实现。从而帮助人们了解一些随语语调规律，以便更有效地学习普通话，减少“普通话水平测试”普通话语调偏误。     

关于发展企业战略联盟的若干思考

20世纪90年代以来,我国出现了为数不少的各种类型的企业联盟。但一些企业联盟在运作中存在各种各样的问题,致使其未能充分发挥联盟的优势。究其原因,是企业联盟的理论尚未得到深入的阐释,结盟企业缺少对联盟科学运作的系统研究。鉴于这种情况,本文从战略联盟的定义入手,分析了战略联盟形成的原因,提出了企业构建战略联盟的几点思考和建议。     

科举学学科的衍生分化:理论、模型与范例(上)

跨学科研究是科举学成为一门科学化学科的重要而独特的方法论。学科之间的整合和衍生分化是科举学跨学科研究的客观要求,也是推动科举学分支学科领域知识创新与转化、生产与增长、发展与壮大的重要方法。通过分析科举学学科衍生分化的基本理论和特点,优化适用于科举学等新兴学科知识衍生分化的"网络模型"及其演化机理,并在理论到实践维度上对科举学分支学科领域创新知识的内部、外部和交叉复合衍生分化进行了应用探索,据此形成了许多科举学分支学科领域的衍生分化范例,这些范例的形成、发展与成熟有助于反思学科衍生分化方法的成效及未来动向。     

Student outcomes and perceptions of instructors' demands and support in online and traditional classrooms

In this study, seven graduate students were interviewed and 187 (91 online; 96 traditional) graduate students were surveyed about perceptions of differences in instructors' demands and support and student' motivation, self-regulation, satisfaction, and perceptions of learning in these environments. Results indicated significant differences in students' perceptions on all variables except self-efficacy. Results indicated a strong effect for differences between perceived instructor affective support in online and traditional classrooms. Although students in traditional classrooms ranked instructors' affective support higher, the variable had a stronger relationship with online students' satisfaction. Differences between online and traditional students' reports of instructors' academic support, instructors' demands, and students' satisfaction were significant with medium effect sizes. Results are important because they provide information about students' perceptions of the differences in environments created by instructors that relate to students' affective outcomes.
