融合SIFT特征和保局投影的人脸识别

提出一种人脸识别方法用于解决姿态变化对识别准确率的影响。首先检测人脸图像的SIFT特征,然后根据SIFT特征计算人脸图像间的多示例距离;基于此多示例距离,用保局投影将人脸图像映射至流形空间,最后在流形空间中采用K近邻方法进行人脸识别。该方法有三个特点：(1)采用SIFT特征减小了未知姿态对识别准确率的影响;(2)通过保局投影将特征变换到流形空间一个点,避免了复杂的SIFT特征匹配策略;(3)借助流形方法滤除高维特征中的噪声。实验结果表明与已有方法相比,在人脸姿态不确定的情况下,该方法能提供较为理想的识别准确率。

On becoming a doctoral student: Chinese doctoral students’ socialization of capital and habitus in academia

Abstract

This study examines Chinese international doctoral students’ academic socialization into TESOL discourses and communities. Rooted in the academic discourse socialization theory, complemented by the notions of Lave and Wenger’s community of practice, and Bourdieu’s capital, habitus, and field, this longitudinal multiple-case study suggest the focal participants’ academic discourse socialization is mediated by their participation in communities of practice, different forms of capital, and habitus in exerting agency. The participants are socialized into academic discourses and communities through their interactions with more experienced colleagues. By participating in the communities of practice, the focal students gain different forms of capital and experience different degrees of competence and memberships. However, due to the inequitable power relations in the TESOL doctoral program field, each participant is socialized to varying levels of central, peripheral, and marginal participation. This study concludes by providing suggestions for action to be taken by university advisors, instructors, and administrators.     

Dose requirements of continuous infusion of rocuronium and atracurium throughout orthotopic liver transplantation in humans

INTRODUCTION Rocuronium bromide is a new steroidal nonde- polarizing neuromuscular blocking drug that has a faster onset of action than other nondepolarizing neuromuscular blocking drugs. The liver is the major route for its elimination. On the other hand, impaired liver function does not alter either atracurium’s elimination or plasma clearance (Ward and Neill, 1983; Pitter et al., 1990). The exclusion of the hepatic circulation and function during the anhepatic phase of orthotopic liv…     

Transformation for adults in an Internet‐based learning environment—is it necessary to be self‐directed?

This research explores the relationships between self‐directed learning readiness and transformative learning theory (TLT) reflected by the Constructivist Internet‐based Learning Environment Scale (CILES). A questionnaire survey about adult learner's perceptions of Internet‐based learning was administered to adults enrolled in classes in community colleges in Taiwan. A total of 593 valid questionnaires were used for the structural equation modeling analysis. The findings confirmed a second‐order hierarchical factor relationship of TLT (technical, dialectical and emancipatory learning interests) from CILES. Moreover, the three domains of learning interests of transformative learning were proved to have a developmental relationship, moderated by the readiness of self‐directed learning for adult learners in Internet‐based learning.

以项目为载体所设计的综合化情境在高职广告策划教学的实践初探

广告策划是浙江旅游职业学院营销与策划专业中一门核心课程,旨在培养学生实际的广告策划与设计能力,具有较强的应用性特征;但是在当前的高职教学中,这种应用性的特征却没有得到突出的重视,学生的实践能力还是有很大欠缺。项目为载体教学法作为一种全新的教学模式和方法,尤其适用于这门课程中,对提高课程教学质量和学生的应用能力都有着突出的功效。文章结合教学实践,就项目教学法在高职营销与策划专业中广告策划课程教学中的具体应用,进行了初步的实践探索。     

马占相思的树干解析

为研究马占相思在早期的生长规律,为其保护、培育和指导规模化生产提供理论依据,以福建漳浦中西国有林场15 a生马占相思为研究对象,通过树干解析,求出树高、胸径、材积与年龄之间的关系曲线。结果表明：15 a生的马占相思在早期生长中生长速度较为恒定,干形削尖。研究结果可用于指导马占相思的规模化生产。     

雾湿天气条件对运动能力影响的研究

为了解雾湿天气对机件各种功能活动的影响，本文在晴朗和雾湿二种天气条件下，对机体最大吸氧量以及完成相同递增负荷直至最大工作能力时机体的体力状况进行研究。结果发现，雾湿天气使最大摄氧量和握力显著下降；进行轻量负荷后，心率和RPE与晴朗天气无异，但进行亚极量以上强度运动后，心率和RPE显著增大；在最大负荷工作时，雾显天气使运动至力竭时间显著缩短，而最大心率和最高血乳酸均显著增大。因此认为，雾湿天气对运动能力有不良的影响，并提示在雾温天气下进行体育教学和训练时要适当降低运动负荷。
