It is confirmed one of the theoretical stances of adaptation theory that there is no language use without being adaptive to context.展开更多

This will cause all kinds of existing and some new security problems in the operation of the integrated network. A complete protection based on recovery is proposed in the paper. It uses the public-key algorithm to authorize and private-key algorithm to encrypt the communicating data. This solution can provide the system with reliable security, and avoid Denial of Service (DoS) of the user. This solution has been proposed lately, and we should further identify the correct action of all the layers and figure out how to react when a legal node is framed by multiple malicious nodes.展开更多

文摘中国和美国都是教育大国,但东西方文化和教育理念的差别带来了大学课堂教学的显著差异。现有研究归纳了美国大学课堂教学中值得中国大学借鉴的诸多经验,但针对具体专业教学的探讨还很欠缺。以我国华中科技大学(HUST)与美国North Dakota State University(NDSU)为例,对工程管理/施工管理专业的课程体系、教学组织、考核评价等方式进行了比较,分析了双方的经验,为国内大学改进工程管理专业课程设置及教学提供借鉴。
