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.  相似文献   

Embodied inter-referencing: encounters with and among “Asian” students in the Australian classroom     

Jane Chi Hyun Park 《Inter-Asia Cultural Studies》2019,20(2):271-289

ABSTRACT

This essay examines the pedagogical practice of referencing my experiences as a transnational Korean American woman in the classroom and considers how it opens up space for domestic and international students of East, Southeast, and South Asian backgrounds to reflect on their different identities, histories, and cultures. In particular, it focuses on how this practice enables Asian students to share their experiences of and insights about racial difference, racism, and whiteness in Australia and other parts of the world. Building on the concept of Asian “inter-referencing” from Chua Beng Huat (2015), I coin the term “embodied inter-referencing” to describe the strategic ways I use autobiographical narrative to create an inclusive, interactive, and mutually respectful learning space. I centre here on how some Asian students respond to this strategy by telling their own stories and in the process, create transnational, diasporic, and inter-Asian affective communities inside and outside the classroom.  相似文献

英语委婉语的形成与交际功能   总被引：1，自引：0，他引：1  

刘驰 《青海师范大学学报(哲学社会科学版)》2003,(2):96-98

由于语言交际是人类赖以维系社会关系和人际关系的重要手段，因而人们在交际中通常避免使用引起双方不快从而损害双方关系的语言，而是采取迂回曲折的方法来表达思想，交流信息，它既是语言修辞的结晶，又是社会化的积淀。委婉语体现了语境和社会化对使用语言的制约和影响，也体现了不同民族对交际方式的要求。  相似文献   

论词境的“空白”     

滕驰 《广播电视大学学报》2008,(3):40-44

“空白”在中国古典艺术中是一个很重要的范畴。中国古典艺术,无论是国画、书法、还是诗词文章,意境之中有空间、有荡漾,神明里透出幽深,不但传达着作者的生命情调,也代表着中国古代文人的宇宙意识。从“空白”论的思想渊源入手,浅析其内在意蕴,及其给词带来的审美特质——空灵,并通过分析“空灵”的美学意义,力图探寻词这种特殊的诗体的内在精蕴,以及词作为有宋一代文学巅峰的文学精神。  相似文献
