一种视频图像中运动目标检测方法研究

针对序列图像中的运动目标检测问题,在独立分量分析的基本理论和算法的基础上,提出采用基于正交对称矩阵的快速定点算法对实际视频图像中的运动目标进行运动检测的方法。实验结果表明:该方法不仅能检测运动轨迹,还能提取运动目标的轮廓,并判断运动方向,是一种有效的运动目标检测方法。     

对高等教育资源浪费根源的制度性分析及对策

在我国高等教育资源相对匮乏的情况下,高校内部资源浪费现象仍大量存在。在高校资源投入的过程中,教育资源配置结构的不合理造成的结构性资源浪费;人力资源结构比例不协调、物力资源利用效率低下、财力资源开支不合理等教育浪费现象,给教育的发展带来了沉重的负担,影响了高等教育的可持续发展。本文在揭示我国高等教育浪费表现及其危害性的基础上,借鉴了新经济制度学对制度问题的研究理论,试图分析高等教育利用效率低下、浪费现象存在的制度根源。针对其产生的制度根源,结合高校的实际,提出相应的对策。     

钢箱梁初步设计近似公式研究

箱型钢梁是薄壁结构,理论上应使用板壳元素为分析元素较能反映实际的受力及变形。为有效进行设计与分析,已有多种商业软件,但是在确定分析元素与分析的前置作业也相当繁杂费时,而造成初步设计的困难。因此如何利用平板力学相关理论推导箱型钢梁受力变形近似公式将可帮助箱型钢梁设计者减少非必要的工作负担。本文的探讨方法是将箱型钢梁上翼板变形分为上翼板与腹板交界处变形及上翼板变形这两种变形的迭加,进而推导出近似公式。直线型式等截面简支箱型钢梁分别用有限元软件SAP2000和近似公式计算进行准确度的比较,误差百分比尚在初步设计的容许误差范围内。

The research pendulum: multiple roles and responsibilities as a researcher

Qualitative research on sexual identities has highlighted the use of oral narratives to understand the lives of lesbians and gay men. Feminist ethnographers, sociologists and queer theorists have further posed methodological inquiries to the issues of insider/outsider, the possibilities of an erotic subject and the matter of representation. Using interview data with Hong Kong lesbians, this paper discusses a researcher's multiple positionalities and its effects on both the researched and the researcher. Being self-reflexive requires a researcher to test her or his own boundaries and to take up social responsibilities as the interpreter of texts. This paper calls for further dialogue between a researcher's subject positions, research processes and the final presentation of findings. doi:10.1300/J155v10n03_02.     

把高校建成传播先进文化的坚强阵地

如何才能把高校建成传播先进文化的坚强阵地,这既是一个理论问题,也是一个实践问题.首先,必须深刻认识高校文化建设的战略意义,始终坚持先进文化发展的前进方向.其次,必须抓住关键,发挥学生的主体作用和教师的主导作用.同时,必须加强领导,齐抓共管,课堂内外,全面渗透,从而营造具有浓厚文化氛围的育人环境,使高校成为传播先进文化的坚强阵地.     

Zone control charts with estimated parameters for detecting prespecified changes in linear profiles

ABSTRACT

In profile monitoring, control charts are proposed to detect unanticipated changes, and it is usually assumed that the in-control parameters are known. However, due to the characteristics of a system or process, the prespecified changes would appear in the process. Moreover, in most applications, the in-control parameters are usually unknown. To overcome these issues, we develop the zone control charts with estimated parameters to detect small shifts of these prespecified changes. The effects of estimation error have been investigated on the performance of the proposed charts. To account for the practitioner-to-practitioner variability, the expected average run length (ARL) and the standard deviation of the average run length (SDARL) is used as the performance metrics. Our results show that the estimation error results in the significant variation in the ARL distribution. Furthermore, in order to adequately reduce the variability, more phase I samples are required in terms of the SDARL metric than that in terms of the expected ARL metric. In addition, more observations on each sampled profile are suggested to improve the charts' performance, especially for small phase I sample sizes. Finally, an illustrative example is given to show the performance of the proposed zone control charts.     

转移支付制度的国际比较与借鉴

论高校少数民族学生宗教信仰与民族团结的关系——以包头师范学院为例

多元化时代的高校,宗教信仰以其较强的心理慰藉功能和行善避恶的教义吸引着大多数少数民族学生,他们活跃于校园的每一个角落,以宗教的核心理念参与校园民族团结建设,在一定程度上推动了校园民族团结.
