Direct - Torque, Neuro - Fuzzy Control of Induction Motor

Fuzzy systems are currently being used in a wide field of industrial and scientific applications. Since the design and especially the optimization process of fuzzy systems can be very time consuming, it is convenient to have algorithms which construct and optimize them automatically. In order to improve the system stability and raise the response speed, a new control scheme, direct - torque neuro - fuzzy control for induction motor drive, was put forward. The design and tuning procedure have been described. Also, the improved stator flux estimation algorithm, which guarantees eccentric estimated flux has been proposed.     

Novice teachers’ learning and knowledge building during the induction programme

This paper explores the Estonian novice teachers’ learning and knowledge building (LKB) practices in the extended professional community during the induction programme using well-known knowledge conversion model. The assumption in this study is that a teachers’ participation in the extended professional community facilitates their professional development. The survey was conducted with 101 novices after their induction programme. The patterns of novices’ LKB practices in the professional learning community during the induction programme were explored. The analysis showed to what extent extended professional community may be formed during the induction year. LKB practice patterns among the novices were identified. We discovered that many novices felt that there was insufficient support from other teachers and from university experts. It appears that it is challenging to develop a coherent induction programme as the extended professional community of educators, where different partners collaborate and share professional knowledge is challenging.

Undergraduates and the development of argument

This article emphasizes the need to encourage undergraduate students to develop arguments, which involves enhancing their analytical skills and capacity for critical thinking, across disciplines regardless of level. It argues that these skills, required by the Quality Assurance Agency＇s （QAA） benchmarks, are developed not by instruction but by engaging with the philosophic process that leads to the deep learning. This process of learning is based on a dialectical approach, viewing dialogue with colleagues, primary texts and written assignments, as central to developing an inductive argument and a critical perspective. This article proposes an analytical framework to analyze the extent to which a tutor is facilitating the development of argument. It suggests that while, if required one must provide students with explicit guidelines about this process, nevertheless this practice is problematic because of the inherent tension between explicit teaching and deep learning, which facilitates the acquisition of these analytical skills.

突破现成话语

现成话语由于其现成性，在很多场合可以自发地涌到嘴边，这种自发的语言常常是歪曲自我的。现成话语把自觉的自我变成现成状态的自我，使真实的自我处在被现成话语淹没的情境中。因此，语言的苍白，乃是心灵的苍白。突破现成话语，也即突破现成的藩篱，找到个人介入社会的方式。     

汉代《诗经》解释学中的哲学机制管窥

汉代《诗经》解释学与阴阳气论哲学、感应哲学密不可分。以汉儒解释《旱麓》《灵台》二诗诗句时所言君王"德及鸟兽鱼鳖"为例,其意义与《吕氏春秋》中言商汤"德及禽兽"而"网开一面"不同,非指君王某一具体行为惠及鸟兽,而是指在天地人同具阴阳之气的基础上,君王之德与自然之气同类相感,在此意义上泽及鸟兽鱼鳖。
