Distributed heterogeneous inspecting system and its middleware-based solution

There are many cases when an organization needs to monitor the data and operations of its supervised departments, especially those departments which are not owned by this organization and are managed by their own information systems. Distributed Heterogeneous Inspecting System (DHIS) is the system an organization uses to monitor its supervised departments by inspecting their information systems. In DHIS, the inspected systems are generally distributed, heterogeneous, and constructed by different companies. DHIS has three key processes-abstracting core data sets and core operation sets, collecting these sets, and inspecting these collected sets. In this paper, we present the concept and mathematical definition of DHIS, a metadata method for solving the interoperability, a security strategy for data transferring, and a middleware-based solution of DHIS. We also describe an example of the inspecting system at WENZHOU custom.

近体诗格律讲座 第三讲 平仄

一、什么是平仄? 平仄是一种声调关系。平,就是平声;仄,就是上去入三声。仄,就是“侧”,就是不平。平声和仄声是对立的。按声调性质(即发音的高低升降),平声是长的,不升不降的,上去入声都是短的,或升或降的(上声是升的,去声是降的,入声特别短促);因此,四声被自然地分为平仄两类。近体诗要求平仄交错。就是在两个诗句中,在本句中平仄是交错的,在对句中平仄是对立的。例如: 平平|仄仄|平平|仄金沙水拍云崖暖仄仄|平平|仄仄|平大渡桥横铁索寒     

多媒体技术条件下的美术基础教学

当代技术背景下的"艺术基础"一直是一个热点话题,本文就此针对"美术基础"认识进行一定程度的探讨。文章从"技术与体验"和"潜在资源"两个方向展开思考,意在强调人文体验的根本性以及基础方法的多元性,企图些许理清"经验与创造","技术与艺术"的惶惑。有时,正确的实践方向有赖于对惯常思维的盘点……     

为生存而自杀

动物的自我牺牲 　　这是一种有五彩翅膀的蝴蝶,它们漂亮的身体能够帮助它们混入周围的环境色来保护自己,而逃过被鸟吃掉的厄运.但是一旦有一只倒霉的蝶儿不幸落入鸟的口中,不仅它自己要丧生,而且它的不幸将连累到它的族中同胞.因为那只尝过这道美味蝶餐的鸟儿对蝶儿的美丽翅膀已记忆深刻,这能够帮助它从蝴蝶隐藏的背景中找到它们,让它们只落得个命丧鸟嘴的下场.要想逃过鸟儿的追捕,则必须身手敏捷,能躲藏于无形,遁逃于瞬间,然而这对于年事已高的老蝶来说,可不是件容易的事,它们行动迟缓,在鸟儿的追捕下很难有逃生的可能.自己遭殃还是小事(老蝶已丧失了生殖的能力,对于种族的繁衍已起不到作用了),但要株连九族,罪过可就大了,它会怎么做呢?它会自己跌落到地上,拼命地扑打自己的翅膀,逐渐耗尽自己的体力,直至死去.为了避免同胞们惨遭毒手,老蝶甘愿牺牲自己,在自己被捕捉之前毁掉自己,包括自己身上的秘密.……     

互联网语境中新闻直播的 传播范式重构 ——以重庆公交车坠江事件为例

随着近年来互联网和移动智能终端的发展,网络直播异军突起,电视新闻直播的话语权和受众不断流失,逐渐被边缘化。在互联网语境中,电视媒体亟需与新媒体融合。本文着重分析电视直播和网络直播的传播特点,结合典型案例,探索互联网语境中新闻直播的传播范式重构。     

大学生幸福感与三周岁以前主看护者之间的相关

以探讨大学生幸福感与三周岁以前主看护者之间的相关为目的,采用幸福感加三周岁以前主看护者问卷对370名大学生进行测量。调查结果显示,大学生幸福感与性别、专业、年级、学历、生源相关不显著,而与三周岁以前母亲是否为主要陪伴养育者之间存在显著相关,相关系数为0.516。从而得出结论,大学生幸福感与三周岁以前母亲是否为主要陪伴养育者之间存在显著相关。

Video segmentation using Maximum Entropy Model

Detecting objects of interest from a video sequence is a fundamental and critical task in automated visual surveillance. Most current approaches only focus on discriminating moving objects by background subtraction whether or not the objects of interest can be moving or stationary. In this paper, we propose layers segmentation to detect both moving and stationary target objects from surveillance video. We extend the Maximum Entropy （ME） statistical model to segment layers with features, which are collected by constructing a codebook with a set ofcodewords for each pixel. We also indicate how the training models are used for the discrimination of target objects in surveillance video. Our experimental results are presented in terms of the success rate and the segmenting precision.     

肇源县小学校长培训方式、步骤及措施

新课程改革的顺利实施,新课程理念的广泛深入,新教学模式的普遍应用……这一切喜人的成果与各级培训部门的努力是密不可分的。作为“校长之家”和“教师之家”的进修学校的培训部门在校长及教师的培训中发挥了积极的作用。 本期围绕着“课程改革中培训的机制和方案”这一主题,选编了一组(三例)比较成功的培训模式,以供其他进修学校的培训部门、小学校长、小学教师参考。另外,为了让一线的校长、教师更好地参与到培训中来,每一例模式中相应地给校长和教师提出了一些要求,希望它能带来一些启示和帮助。
