NFC协议的模糊测试优化方案

针对NFC协议进行模糊测试方案时产生大量不符合协议规范的无效测试用例而导致测试效率较低的问题,应用图论思想,提出了基于生成的策略与深度优先算法融合后的模糊测试方案。在基于生成的策略下构造测试用例的过程中,遍历由协议规范连接成的测试需求图,以深度优先算法搜索图中覆盖点较多的生成路径,精简测试用例的生成路径,保证生成的测试用例能够接近协议规范。实验分析表明,所提出的模糊测试方案能够有效地减少无效测试用例的生成,提高测试效率。     

人文生态理念下城市生态住区的和谐建构

随着我国住区规划的理论研究从物质功能主导转为人居环境和社区情感,对社会、文化、心理等的"深生态"问题引起了大家的关注。在分析城市生态住区建设发展现状的基础上,指出现阶段我国城市生态住区建设中存在的问题,提出在自然生态的基础之上,还应具有独特、丰富的人文生态,凸显人文内涵是城市生态住区建设的必要前提。同时,文章以人文生态的内涵为出发点,探讨了人文生态理念下的城市生态住区建设策略。     

基子知识视角下的企业家精神

本文通过封国内外有关知识资本、企业家和企业家精神的文献研究和总结，在知识视角下封企业家理论进行简要回顾，得出企业家精神的实质是创新精神，更是识别创新机会、把握创新机会的过程的结论。使用信号传递模型，分离条件假设以及斯宾赛一莫裹斯条件建立模型，说明企业家的沟通成本对企业创新的影响。本文为企业家精神的研究提供一个新的视角或认识工具。

How does the effect of pre-play suggestions vary with group size? Experimental evidence from a threshold public-good game

Numerous studies have examined factors influencing the likelihood of cooperative outcomes in nonzero-sum games, but there has been little study of the interaction between two of the most important: group size and pre-play cheap talk. We report results from an experiment in which groups of size between 2 and 15 play a one-shot multi-player threshold public-good game. In our random leader treatment, all group members select a suggestion (e.g., “Everyone should choose X”), with one randomly chosen to be broadcast to the group. In a choice only treatment, subjects choose suggestions but none is sent, and in a baseline treatment, there are no suggestions at all. We find a negative interaction between group size and this kind of communication: the beneficial effect of both suggestions overall and cooperative suggestions on cooperation, cooperative outcomes, and payoffs decreases sharply as the group size increases. We find a similar negative interaction in a follow-up treatment in which all group members’ suggestions are broadcast to the group. Our results suggest that care should be taken in generalising conclusions from small-group experiments to large groups.     

双向多中继协同通信系统的性能分析

针对频率非选择性瑞利衰落信道,研究了双向多中继协同通信模型的系统性能。首先,基于模型的信号传输过程分析了系统的信道容量;然后,根据接收信噪比的累积分布函数推导了系统中断概率的闭合上界表达式;进一步在MPSK调制方式下,通过计算在高信噪比条件下的矩母函数,推导了平均误码率的闭合表达式。仿真结果验证了理论推导的正确性,并且表明双向多中继模型的中断概率和平均误码率两项性能指标都优于双向单中继模型。     

Assessing the regional digital divide across the European Union-27

Despite the efforts devoted to the analysis of the digital divide over the last years, the regional evidence on this issue is still scarce. Within this context, the goals of this paper are twofold: (1) measuring the digital divide across the regions of the 27 Member States and within each country and (2) explaining the observed regional disparities. The analysis leads to identify Dutch regions as the Top-10 in ICT, while Greece and Bulgaria occupy the Bottom-10. Therefore, results show that the regional digital divide reflects to some extent the income gap. However, regional policy seems to be having some positive implications for technology adoption. In particular, the rural-versus-urban dimension of the digital gap appears to be less important than it is usually claimed to. Likewise, some evidence is found of the role of cultural and institutional factors in ICT adoption, an issue that has not been previously analyzed at the regional level.     

一种基于非正交信道的分布式中继选择及功率分配方法

针对非正交两跳多中继协作通信系统中的分布式中继选择问题,提出了一种基于非正 交信道的中继选择准则,简化了系统的设计。分析了其误码率性能,给出了其解析表达式 和以总功率为约束条件下的最优功率分配方案。仿真结果表明,最佳中继选择准则明显优于 传统的中继选择准则,且在最优功率分配方案下,可以获得明显的分集增益,系统的误码率 显著下降。
