流量域概念下的多校区模块化组网实践 总被引:1,自引:0,他引:1
流量域是某个网络作用范围内相同或相似流量因素的集合.面对日趋复杂的校园网应用需求,充分考虑多校区情况下学校各业务系统对网络带宽、网络安全、服务质量、策略管理等方面的要求,积极探索按流量域划分的模块化网络建设新模式,使各功能子网既有机联系又相对独立,杜绝冲突与碰撞,可以为广大师生员工提供更高性能、更高安全、更灵活易管理的网络应用平台,同时为数字化校园的实现打下更为坚实的基础. 相似文献

Happiness and suffering are both the result of two factors combined: the situation in which one is placed and our consciousness
of it. Happiness is not only of personal importance, it is also a necessary factor for ensuring peace in society. Therefore
it is important to know the two possible ways for the pursuit of happiness: applied science, which focuses on how situations
can be controlled, and spirituality, which focuses on developing the various types of consciousness one can have. The notion
of purified consciousness is formulated in terms of psychology, neurophysiology, logic and meditative practice.

This paper discusses the organization of software that is inherently complex because of very many arbitrary details that must be precisely right for the software to be correct. We show how the software design technique known as information hiding, or abstraction, can be supplemented by a hierarchically structured document, which we call a module guide. The guide is intended to allow both designers and maintainers to identify easily the parts of the software that they must understand, without reading irrelevant details about other parts of the software. The paper includes an extract from a software module guide to illustrate our proposals. 相似文献

图像方向性在空域和频域中的特性研究 总被引:1,自引:0,他引:1
文章研究了图像的方向性在空域和频域分析中的不同特性。首先,建立了图像的空域模型和频域模型,对两者的特性进行了数学分析,并且通过一定的仿真实验进行了验证。结果表明,图像的空域方向性和频域方向性之间存在着确定的关联性。这一特性在图像的频域分析中有着至关重要的作用。 相似文献

Throughout much of the modern period, the human mind has been regarded as a property of the brain and therefore something confined to the inside of the head—a view commonly known as ‘internalism’. But recent works in cognitive science, philosophy, and anthropology, as well as certain trends in the development of technology, suggest an emerging view of the mind as a process not confined to the brain but spread through the body and world—an outlook covered by a family of views labelled ‘externalism’. In this paper, we will suggest there is now sufficient momentum in favour of externalism of various kinds to mark a historical shift in the way the mind is understood. We dub this emerging externalist tendency the ‘New Mind’. Key properties of the New Mind will be summarised and some of its implications considered in areas such as art and culture, technology, and the science of consciousness. 相似文献

利用多媒体课件辅助教学不仅促进教学方法的更新和发展,而且有助于改变传统的教育思想和模式。课件的制作必须在一定的理论指导下进行,否则用传统的思想制作出来的课件很容易变成"人灌"加"电灌",达不到预期的教学目的。 相似文献

A designer's expertise rests on the knowledge and skills which develop with experience in a domain. As a result, when a designer is designing an object in an unfamiliar domain he will not have the same knowledge and skills available to him as when he is designing an object in a familiar domain. In this paper we look at the software designer's underlying constellation of knowledge and skills, and at the way in which this constellation is dependent upon experience in a domain. What skills drop out, what skills, or interactions of skills come forward as experience with the domain changes? To answer the above question, we studied expert designers in experimentally created design contexts with which they were differentially familiar. In this paper we describe the knowledge and skills we found were central to each of the above contexts and discuss the functional utility of each. In addition to discussing the knowledge and skills we observed in expert designers, we will also compare novice and expert behavior. 相似文献
