临时性词汇认知运作机制探讨——以“出租车司机家”为例

以"出租车司机家"为例,在认知语言学的理论框架之下,运用射体-界标关系对临时性词汇(也称"语境词")进行了分析,分析结果表明:和出租车司机这个结构相比,"出租车司机家"突显程度更高,其中名词"家",更强于出租车司机的突显名词"司机",因而更能加强接受者的注意;"出租车司机家"主要的认知方式是仿拟,与语境有着密切的联系。     

无线自组网络及其在教育中的应用

无线自组网是一种聚集两个或多个具有无线通信能力和网络联机能力的设备,且设备可以直接在它们的无线覆盖范围之内或一个是在它们的无线覆盖范围之外的其他设备相互连接进行通讯,不必透过AP来进行通讯连接。如有几台手机或笔记本电脑,当它们聚集在通讯的链结范围内,就可以形成一个临时的网络。简单评析无线自组网其自身技术特点以及其在教育领域的应用。     

Ad hoc网络中带有DoS阻断功能的密钥管理策略

在Ad hoc网络中密钥的安全问题已经成为研究热点,本文首先对存在的安全隐患进行了分析描述,然后从节点间信任角度出发,结合Ad hoc网络自身特点,提出了一种带DoS入侵阻断功能的分布式密钥管理策略,用于保证整个网络的安全性,提高了网络性能。     

Bibliographies of East European Newspapers at the Library of Congress

This article traces the development of recent bibliographies of East European newspapers held by the Library of Congress. Since 2006 the European Division of the Library of Congress has placed ten newspaper bibliographies onto its website for the following countries: Bosnia and Herzegovina, Bulgaria, Croatia, Hungary, Hungary 1956, Kosovo, Macedonia, Montenegro, Russia, and Serbia, as well as a mixed newspaper/journal bibliography of the Soviet independent press, 1985–1992. The author covers topics such as the need for such bibliographies, their collection development benefits, the difficulty in maintaining their currency, and their popularity based on website statistics.

Alumni Perceptions of a Move to NCAA Division IA Football Membership

ABSTRACT

Because of its prominent role, football has the potential to positively impact a university in several ways. Previous research on college athletics has focused on the financial impact of athletic success on institutions (e.g., donations). This research examines the marketing capabilities of college football by measuring alumni perceptions of a large southeastern university's move to NCAA Division IA football. A total of 297 alumni participated in a telephone survey. A high percentage of alumni believe IA football is prestigious and that the move to IA has influenced game attendance intention. Alumni believe the university's image has been positively influenced by the move to IA, and 21% believe the perceived value of their college degree has been enhanced by the move to IA. Findings from this study can aid universities in understanding the importance of football to alumni and how athletics can keep alumni connected with their alma mater.

基于用户协作PDMA的星地融合网络性能分析

将用户协作PDMA技术引入到星地融合网络下行链路系统的通信中,目的是当卫星向用户发送PDMA叠加信号时,其中最佳信道用户能够作为半双工中继节点解码和转发其他用户的信息,以提高弱用户的通信性能。文章推导出三用户处于不同程度衰落情况下系统的中断概率和遍历容量表达式,并通过仿真验证了理论分析的正确性,而且证实了与传统的正交多址接入及非协作PDMA系统相比,用户协作PDMA方案可以获得更高的中断性能和遍历容量。     

基于Ad Hoc网络的典型路由协议的研究与NS2仿真

目前Ad Hoc网络有三种典型的路由协议,即先发性（Proactive）路由协议、反应性（Reactive）路由协议和混合性（Hybrid）路由协议。本文分析了上述协议,并给出几个典型的路由协议NS2仿真分析。
