基于数学文化观的高等数学教学模式研究

许多教育工作者对高等数学教学模式进行了大量的探索和研究。但对于高等数学教育人们只重视其工具性价值,而忽略了数学的文化教育价值;本研究就是要把高等数学教育提高到数学文化教育的层面,不仅重视数学知识的传授、数学技能的训练、数学能力的培养,而且使数学文化与数学教育相结合,最终目的是提高学生数学素养,为学生的终身学习和可持续发展奠定良好的基础。

Networked H∞ filtering for Takagi–Sugeno fuzzy systems under multi-output multi-rate sampling

This paper studies networked H_∞ filtering for Takagi–Sugeno fuzzy systems with multi-output multi-sensor asynchronous sampling. Different output variables in a dynamic system are sampled by multiple sensors with different sampling rates. To estimate the signals of such a system, a continuous multi-rate sampled-data fusion method is proposed to design a novel networked filter. By considering a class of decentralized event-triggered transmission schemes, multi-channel network-induced delays, and the updating modes of the MOMR sampled-data, a networked jumping fuzzy filter is proposed to estimate system signals based on the transmitted multi-rate sampled-data of fuzzy system and the multi-rate sampled states of filter, and the jumping among filter modes is governed by a Markov process which depends on the arrival times of sampled output sub-vectors. To deal with asynchronous membership functions, the networked fuzzy filtering system is modeled as an uncertain fuzzy stochastic system with membership function deviation bounds. Based on stability and H_∞ performance analysis, several membership-function-dependent conditions are presented to co-design the event-triggered transmission schemes and the fuzzy filter such that the filtering error system is robustly mean-square exponentially stable with a prescribed H_∞ attenuation level. Finally, the improvement in estimation performance and comparison with the existing filtering methods are discussed through simulation examples.     

Long Distance Relationships: Assessing the Library Service Needs of Rural Students in eLearning Courses

ABSTRACT

In states with limited road accessibility, rural students can feel isolated from library services. This article explores the creation, implementation, and results of an on-going longitudinal study assessing the library service needs of rural students in eLearning courses. To align with current practices in online pedagogies, including the Association of College and Research Libraries' Standards for Distance Learning Library Services and recent revisions to the Framework for Information Literacy for Higher Education, this survey has been designed to help the library identify and improve services to enhance rural student success.
