一种支持Qos约束的Web服务模型框架及实现

服务质量（Qos）在Web服务技术中越来越受到人们的重视，Qos的好坏是web服务在商业应用中是否能够取得成功的关键。现有web服务并不支持Qos，对现有的Web服务模型进行了扩展，支持带有Qos约束的服务描述，对服务提供者报告的Qos和服务使用者需求的Qos进行认证处理，从而提高了服务的质量。

一种鲸鱼优化算法改进的加权质心定位算法

针对加权质心定位算法受 RSSI 测距误差影响导致定位结果不理想的问题,提出一种鲸鱼优化算法改进的加权质心算法,利用鲸鱼优化算法的快速收敛、不易陷入局部最优等优势对加权质心算法定位结果进行优化。首先,通过加权质心算法计算待测点位置;其次,根据锚节点位置信息、RSSI 测距信息及待测点位置信息建立适应度函数;最后,利用鲸鱼优化算法不断迭代寻优,对待测点定位结果进行优化,以提高定位精度。在通信半径相同、锚节点数为 30 的条件下,改进后的定位算法定位精度为 0.58m,而粒子群加权质心算法与人工鱼群加权质心算法定位精度分别为 0.64m 和 0.62m,且随着锚节点个数的增加或通信半径的增大,改进后的定位算法仍能获得更高的定位精度。因此,改进后的定位算法精度更高,具有一定可行性。     

Promoting cognitive and social aspects of inquiry through classroom discourse

We investigated how Chinese physics teachers structured classroom discourse to support the cognitive and social aspects of inquiry-based science learning. Regarding the cognitive aspect, we examined to what extent the cognitive processes underlying the scientific skills and the disciplinary reasoning behind the content knowledge were taught. Regarding the social aspect, we examined how classroom discourse supported student learning in terms of students' opportunities to talk and interaction patterns. Our participants were 17 physics teachers who were actively engaged in teacher education programs in universities and professional development programs in local school districts. We analyzed one lesson video from each participating teacher. The results suggest both promises and challenges. Regarding the cognitive aspect of inquiry, the teachers in general recognized the importance of teaching the cognitive processes and disciplinary reasoning. However, they were less likely to address common intuitive ideas about science concepts and principles. Regarding the social aspect of inquiry, the teachers frequently interacted with students in class. However, it appeared that facilitating conversations among students and prompting students to talk about their own ideas are challenging. We discuss the implications of these findings for teacher education programs and professional development programs in China.     

基于BIM的工程管理专业毕业设计模式探索

毕业设计作为本科阶段最重要的一项实践活动,现在已经很难让学生取得巨大的进步,所以毕业设计急需进行改进.工程管理作为最贴近工程实际的专业之一,通过运用BIM技术,将进行毕业设计的学生按专业分组,形成团队毕业设计,同时也可以将工程管理与土木工程等专业进行结合,将毕业设计的所有权限下放给学生,成为一种高校毕业设计的新模式,实现学生团队意识、专业素养全面发展.     

创新观念，努力提高职业教育的质量和效益

观念的创新是教育创新的关键,职业教育必须建立与社会主义市场经济体制相适应的教育观念。本文对职业教育乃至整个教育领域应该引入和强化的“服务”观念、“产品”观念、“顾客”观念、“质量”观念和“效益”观念进行了初步分析和探讨。     

Transmission line realization of subwavelength resonator formed by a pair of conventional and LHM slabs

INTRODUCTION Left-handed materials (LHMs), first investigated theoretically by Veselago (1968), have received sub- stantial attention in the scientific and engineering communities. The unique properties of these meta- materials are promising for a diversity of microwave applications, such as new types of beam steerers, modulators, filters, superlens (Pendry, 2000), cou- plers and antenna radoms (Smith et al., 2004). Re- cently, a transmission line (TL) approach has been successfully in…
