基于云计算的应用架构和服务模式研究

从云计算的内涵、特点入手,系统性地总结和分析云计算的服务特点与设计理念,在此基础上,针对云计算对用户应用影响面最广的问题,归纳并提出了云计算机的三种基本服务模式:基于基础设施的服务、基于通用平台的服务、基于个性化用户功能的服务,分别对每一种服务模式特点和适应面进行研究。最后总结出云计算在发展过程中需要解决的几个关键问题。     

OSI参考模型的教学方法

《计算机网络基础》课程是一门发展着的前沿学科,是我院本、专科各专业必修的一门专业基础课程,是通信技术与计算机技术相结合的产物,内容广泛,学习难度较大,尤其在学习计算机网络体系结构这部分知识时,学生的学和教师的教都认为是一重点,也是一难点。所以,本文将从一实例出发逐渐推导出计算机网络体系结构模型OSI/RM的教学内容,从而使学生进一步了解什么是计算机网络体系结构。

Reuse of clips in cartoon animation based on language instructions

INTRODUCTION tic in-betweening techniques have been proposed during the past 30 years (for a comprehensive review of automatic in-betweening methods, please refer to (Yu and Patterson, 1997; Gotsman and Surazhsky, 2001)), their use in computer aided systems is some- how limited to dealing with local movements only (Yu and Patterson, 1997), because exaggerated drawings used in cartoon animations follow animation princi- ples and do not respect the geometry (Patterson and Willis, 1994) tha…

Potential for knowledge in action? An analysis of Korean green energy related K3–12 curriculum and texts

While understanding green energy development and what drives it are important, there is increasing consensus that sustainability transitions concerning usage need to be viewed in terms of the place specific contexts, including education, that critically mold them. In order to support sustainability transitions, information and knowledge building are not enough; knowledge must be turned into action. This research examines the potential efficacy of Korea’s efforts in this regard via an analysis of K3–K12 geography education curriculum and texts vis-à-vis green energy content. There is scant disconnect between the curriculum and the texts analyzed, and, aside from the small shortcomings unearthed, analyses suggest that Korea is cogent of the ability of geography education and education for sustainable development to turn knowledge into action, thereby empowering civil society to drive its green energy transitions going forward.

一种用于大规模动态异构信息集成的多代理结构

为了在集成大量异构自治信息资源时实现高效率互操作性,设计了一种基于智能体(agent)的多代理结构.用一组代理智能体以peer-to-peer(P2P)方式为其他非代理智能体提供代理服务,从而提高系统的可扩展性与健壮性.代理服务使用本体技术来实现系统互操作性.与其他多代理结构不同的是,除了领域内本体,还引入了一个领域间本体来表达各个领域内本体中公共概念的联系.因此,代理可以根据领域间本体的信息,将查询请求仅发往相关的代理,减少了网络通信量,更好地发挥多代理体系结构的优势.实验结果表明,系统实现互操作性的效率相对于现有的系统有明显的提高.     

死刑执行救济程序研究

死刑执行救济程序是限制死刑适用的途径之一。我国的死刑执行救济需要在《刑法》中增设判处死刑的被告人有权请求赦免或减刑的条款,赋予救济的实体依据;《刑事诉讼法》中明确死刑执行救济的决定权主体和适用对象,明确特赦和减刑理由及其程序,明确死刑判决生效到执行之间适当的时间间隔。
