可编程序控制器的电平信号输入

针对可编程序控制器只接受物理开关量和模拟量,而不能直接输入数字量（电平信号）的现实问题,通过剖析可编程序控制器的原理、结构,对输入电路进行改造处理,从而使可编程序控制器在接受物理开关量和模拟量的同时,也能接受数字量,拓展了其应用。     

具有两个生成元的小波框架的信号去噪

介绍了小波框架的基本知识和小波框架的分解重构算法,及小波框架阈值去噪算法,对Haar小波、db4小波、sym8小波和小波框架进行去噪实验,仿真实验结果表明最小能量小波框架去噪效果优于Haar小波、db4小波、sym8小波的去噪效果.     

论《连尔居》中的个性化叙事

熊育群从八十年代便开始诗歌、散文的创作,几十年的积累沉淀,为其小说创作打下了坚实的基础．也奠定了熊育群小说语言、结构等方面的风格。《连尔居》是熊育群初涉小说的第一部作品,讲述遗世独立的连尔居．那里有荒沼地上的村庄,人们自由率性地生活。他着力从小说的环境、情节、人物三个方面．突出其小说创作的个人化特色。     

无线电信号传输的区域覆盖

以一个无线电信号覆盖圆域的工程问题为例,建立了用若干个小圆覆盖大圆区域的数学模型并求出其最优解,同时还给出了实现最优方案的充分条件和必要条件。对于较少用户情形,以覆盖效率为指标确定实现面积覆盖的最少小圆数目;对大容量用户,综合考虑用户密度和覆盖密度进行网格设计,在保证完全覆盖的同时避免了通信设备的闲置和拥堵,使方案达到最优。采用的方法可推广到一般情形,对通信工程中信号传输覆盖问题有一定的指导作用。     

Prioritising student voice: ‘Tween’ children's perspectives on school success

This paper presents the findings of a study of the perspectives of Australian, English and New Zealand ‘tweens’ in response to one question, ‘what makes people muck up at school?’ Arguing for the increased prioritisation of children's voices in educational planning and provision, this paper provides, in children's own words, their perspectives on school success and classroom dynamics.     

Pupils' perspectives on the lived pedagogy of the classroom

This paper is based on a pedagogical action research initiative that explores what constitutes the ‘lived pedagogy’ of the classroom from the pupils' perspective. Photography and group interviews were utilised to allow pupils to express their perspectives. The results show that pupils considered situations meaningful when they were able to work, solve problems and create items together. The pupils appreciated situations in which they experienced a sense of belonging and could influence the use of time and space during the school day. The paper considers possibilities and challenges related to acknowledging pupils' voices in the lived pedagogy of the classroom.     

女性话语权的建构--从福柯的话语理论分析《女勇士》

汤亭亭的小说《女勇士》是当代美国华裔文学的代表作品之一,反映了美国华人尤其是女性在美国社会找寻自身归属的过程中的挣扎与奋斗。文本中的五位女性在男权的压迫和支配下,打破沉默,发出了自己的声音,颠覆男性话语中心。该文将从福柯的话语理论出发,重构“女勇士”这一复杂形象,探讨女性是如何在多种冲突的社会环境中建构话语权,并在失声到发声的过程中于边缘徘徊,举步维艰。

Supporting pre-service teachers to enhance the effectiveness of their classroom practice through engaging with the ‘voice’ of their pupils

The research reported here was focussed on accessing the perceptions of pre-service teachers regarding the critical factors which support highly effective learning in schools in the United Kingdom. Their perceptions were arranged into a taxonomy so that they can be used as a starting point for their reflections on the observations they make of teaching and learning in schools with the aim of enhancing the effectiveness of their own teaching. The choice of technique used to access the perceptions was driven by the desire to provide the pre-service teachers with a method that they could use themselves to engage with the ‘voice’ of their own pupils regarding the factors which support effective learning. The engagement of pupil voice has become increasingly significant in understanding effective pedagogy and in securing more personalised approaches to learning in United Kingdom school contexts.     

火焰信号计算机集中管理系统的应用

姚孟电厂#3、#4机组的火检系统是八十年代初采用比利时考利尔公司生产和提供的成套装置,火焰检测探头为ISCAN FLAMESCANNER型智能扫描仪,无需二次信号处理器,系统改造后,引进了火焰信号计算机集中管理控制.本文介绍了火焰信号计算机集中管理系统的安装和使用,并就火检系统运行中存在的问题提出了个人设想.
