在大学英语教学中引入英语文化教学

语言是文化的重要组成部分,它既是表现文化的主要手段,又是文化的载体。语言和文化的关系决定了英语教学中离不开英语文化的教育。本文阐述了在大学英语教学中进行英语文化教学的现状、意义,并论述了英语文化教学导人的内容和方法。     

大学英语教学中合作学习模式的应用

合作学习是一种以小组活动为主要形式的教学理论与策略体系。合作学习理论为我们提供了大学英语学习的新视角,促进了教学的多维互动,催生了大学英语课堂教学的新形式,更新了教学的评价机制。了解合作学习的模式、合作学习在大学英语教学中的实施和其在现实教学中存在的一些问题,有利于更好地做好大学英语教学工作。

注意理论对英语词语搭配教学的启示

二语习得研究表明输入的注意和认知处理对二语词汇习得非常重要。词语搭配是词汇学习中极为重要的组成部分,学习词语搭配是提高英语交际能力的有效途径。因此教师应根据有关注意理论及心理学理论,在语言教学中研究教学策略,帮助学生提高对词语搭配的学习,有效习得词语搭配,从而提高英语综合能力．     

约束带系统的试验研究

约束带系统是儿童约束系统的一个组成部分,其性能直接关系到车内儿童乘员的安全。文章介绍了通过对不同儿童约束系统标准的研究,建立起符合标准的试验装置,并根据规定的步骤对约束带进行试验和判定。指出按照这种方法可完整地时约束带系统进行合理地评价,并可通过上述试验装置及试验方法来考核约束带系统的性能和质量,以保证儿童乘员的安全,为C-NCAP增加儿童安全座椅方面的测试内容做准备。     

复合型外语人才的培养与ESP

随着我国改革开放,市场经济的不断推进,单一的外语类毕业生已不适应社会的需求。转变教育思想,更新教育观念,培养适应社会需求的高素质、高质量的复合型人才,已成为各高校的共识。     

Online license plate matching procedures using license-plate recognition machines and new weighted edit distance

License-plate recognition (LPR) technology has been widely applied in many different transportation applications such as enforcement, vehicle monitoring, and access control. Recently, there has been effort to exploit an LPR database for vehicle tracking using popular template matching procedures. Existing template matching procedures assume that the true reference string is always available. However, under a two-point LPR survey, a vehicle could have its plate misread at both locations generating a pair of misread strings (or templates) with no reference for matching. To compensate for LPR misreading problem, we propose a new weight function based on a probability model to match the observed outcomes of a dual LPR setup. Also, considering that reversal errors are never made in LPR machines, new editing constraints as a function of the string lengths are proposed to avoid compensation for reversal errors. These editing constraints are incorporated into the constraint edit distance formulation to improve the performance of the matching procedure. Finally, considering that previous template matching procedures do not take advantage of passage time information available in LPR databases, we present an online tracking procedure that considers the properties of probability distribution of vehicle journey times in order to increase the probability of correct matches. Experimental results show that our proposed procedure can improve the accuracy of LPR systems and achieve up to 97% of positive matches with no false matches. Further research is needed to extend the ideas proposed herein to plate-matching with multiple, i.e., more than two, LPR units.     

Evaluate bus emissions generated near far-side and near-side stops and potential reductions by ITS: An empirical study

In this paper, we use second-by-second automatic vehicle location data to estimate bus emissions near far-side and near-side stops. We classify the bus running state near a stop into approach, dwell, and departure. A vehicle specific power approach is used to estimate bus emissions for each state. We show that bus emissions generated near stops can be significantly reduced by using certain intelligent transportation systems techniques.     

Constraints to green vehicle ownership: A focus group study

We consider constraints that prevent people with environmental concerns from buying “green” vehicles that are smaller, more fuel-efficient, and less polluting by using a series of focus group discussions. We find that the features of vehicles currently on the market, family and work responsibilities, residential choices, and routines and preferences all act as constraints. Serious misunderstandings about the environmental impacts of owning and using vehicles also were noted, making it difficult for many to accurately assess their alternatives. For some, environmental concerns are unlikely to influence future vehicle purchase decisions, even if constraints were removed altogether; other priorities have taken and will take precedence over the environmental impacts of their choices.
