周红萍  吕万刚 《武汉体育学院学报》2020,54(8):65-71

研究新中国成立70年来体育教育专业人才培养特征与演变规律，是呈现体育教育专业发展历史的需要，是推动体育教育专业发展和改革的一项基础性工程。采用文献资料法、历史法、专家访谈法和逻辑分析法，对体育教育专业发展规模、专业定位、培养方案、课程设置、教学模式等方面开展研究，结果表明：新中国成立70年来，体育教育专业经历了学习与移植、探索与挫折、混乱与恢复、开放与改革、提速与跨越、实践与创新的演变过程。表现出专业规模不断扩大、培养目标由单一向多元发展、课程设置逐渐模块化和弹性化、选修课和实践课学时逐步增加、总学分缓慢降低、人才培养模式多样、教学方法不断更新等特征。这些演变是基于国际国内的政治、经济、文化和科技发展的历史缘由。当下，专业认证已全面铺开，坚持"一流专业"建设是培养卓越体育教师的根与本。  相似文献   

战略性新兴产业与经济发展耦合协调发展研究——基于安徽省的实证研究     

谢国根 《科技管理研究》2018,(22)

基于系统耦合理论,对安徽省战略性新兴产业系统与区域经济系统的耦合协调发展状况进行测度和系统评价。结果显示,安徽省大多数地级市的战略性新兴产业与区域经济并未实现同步型发展,但两者发展的一致性程度在逐渐提升;就两者耦合协调度而言,总体偏低,大多数地级市仍处在中低度耦合阶段,但在时间序列上呈现逐渐提升的态势,总体状况趋于良性发展;在空间格局上,耦合协调度一定程度上呈现以合肥、芜湖为中心逐渐向外围扩散的趋势,但中心城市对周边地区耦合协调程度提升的辐射和带动作用还有待进一步加强。  相似文献

Evaluation of fault diagnosability for networked control systems subject to missing measurements   总被引：1，自引：0，他引：1  

Fangzhou Fu  Dayi Wang  Ping Liu  Wenbo Li 《Journal of The Franklin Institute》2018,355(17):8766-8779

The evaluation of fault diagnosability for networked control systems subject to missing measurements is addressed in this paper. In particular, the missing probability is assumed to be affected by norm-bounded uncertainties. By considering noise and missing measurements, the quantitative diagnosability problem is investigated via the principle of weight. To quantify the effect of uncertain missing probabilities, an interval criterion is presented and uncertainty ratio is defined. Furthermore, a novel method is proposed to alleviate the computation task of evaluating fault diagnosability. The effectiveness of the proposed method is verified by a numerical example.  相似文献   

重释知识产权的对象     

贾小龙  管慧慧 《科技管理研究》2019,(19)

知识产权对象与客体的界定长期无法达成一致,对知识产权法学的体系化具有不利影响。从传统民事权利对象的界定方法来看,知识产权的对象就是知识和信息,是有价值、可再现并与现有知识、信息相区别的知识和信息,具体包括作品、专利技术方案、商标以及其他未公开的信息。结合权利的本质可知,知识产权的客体就是利用这些知识信息所生之利益。权利客体的财产性和权利对象的独特性,是知识产权成为独立一类民事权利的二元依据。  相似文献   

Semi-global leader-following coordination of multi-agent systems with input saturation and aperiodic intermittent communications     

Zhipeng Fan  Housheng Su  Shiming Chen  Minghui Yu  Jie Ma 《Journal of The Franklin Institute》2019,356(2):1051-1066

This paper addresses the semi-global leader-following coordination problem of general linear multi-agent systems, in which the control input of each agent is steered by aperiodically intermittent saturated actuator. Both the case with only one virtual leader and the case with multiple virtual leaders are discussed. By using multiple Lyapunov stability theory and applying algebraic Riccati equation-based low-gain feedback technique, sufficient conditions guaranteeing semi-global consensus tracking and semi-global containment tracking are provided. Numerical simulations finally verify the theoretical analysis.  相似文献   

Stabilization of switched linear singular systems with state reset     

Xiaoqing Xiao  Ju H. Park  Lei Zhou 《Journal of The Franklin Institute》2019,356(1):237-247

This paper investigates the stability and stabilization of switched linear singular systems with state reset at switching instants. Based on the dynamics decomposition of singular subsystems, a sufficient stability condition for the system with the given state reset is obtained. Then, the stabilization problem by state reset is investigated and an algorithm for computing the reset matrices is presented. The obtained results extend some previous works on both singular switched systems and reset control for normal switched systems. Finally, a numerical example is presented to illustrate the effectiveness of the proposed approach.  相似文献   

Observer-based decentralized control of large-scale stochastic high-order feedforward systems with multi time delays     

Liang Liu  Shengyuan Xu  Xue-Jun Xie  Bing Xiao 《Journal of The Franklin Institute》2019,356(16):9627-9645

This paper investigates the problem of observer-based decentralized control for a class of large-scale stochastic high-order feedforward systems with multi time delays. By using the homogeneous domination idea and constructing the implementable observer, the decentralized output-feedback controller design scheme is firstly proposed. Then, with the aid of stochastic time delay system stability theory, the globally asymptotically stable in probability of the closed-loop system is verified by selecting an appropriate Lyapunov–Krasoviskii functional. Finally, an example is provided to demonstrate the efficiency of the proposed design method.  相似文献

Fixed-time outer synchronization of hybrid-coupled delayed complex networks via periodically semi-intermittent control     

Qintao Gan  Feng Xiao  Hui Sheng 《Journal of The Franklin Institute》2019,356(12):6656-6677

In this paper, the fixed-time synchronization between two delayed complex networks with hybrid couplings is investigated. The internal delay, transmission coupling delay and self-feedback coupling delay are all included in the network model. By introducing and proving a new and important differential equality, and utilizing periodically semi-intermittent control, some fixed-time synchronization criteria are derived in which the settling time function is bounded for any initial values. It is shown that the control rate, network size and node dimension heavily influence the estimating for the upper bound of the convergence time of synchronization state. Finally, numerical simulations are performed to show the feasibility and effectiveness of the control methodology by comparing with the corresponding finite-time synchronization problem.  相似文献
