专利与技术标准相互渗透对技术创新的影响     

郭炬  陈为旭 《福建教育学院学报》2011,(2):46-49

将专利纳入标准是一种必然趋势,在这一过程中,如何均衡各利益相关方之间的关系,在保证技术产权的同时防止专利权滥用,值得探讨。本文分析了专利、技术标准和技术创新之间的关系,为解决由于专利与标准的结合而造成对技术创新的阻碍提出了建议。  相似文献   

Stabilizability of complex complex-valued memristive neural networks using non-fragile sampled-data control     

Ruimei Zhang  Deqiang Zeng  Ju H. Park  Kaibo Shi  Yajuan Liu 《Journal of The Franklin Institute》2021,358(4):2320-2345

This paper investigates the stability and stabilizability of complex-valued memristive neural networks (CVMNNs) with random time-varying delays via non-fragile sampled-data control. Taking the influence of gain fluctuations into account, a non-fragile sampled-data controller is designed for CVMNNs. Compared with the existing control schemes, the one here is more applicable and can effectively save the communication resources. The assumption on activation functions of CVMNNs is relaxed by only needing the complex-valued activation functions satisfying the Lipschitz condition. By constructing a suitable Lyapunov–Krasovskii functional (LKF), new stability and stabilizability criteria are derived for CVMNNs. Different from the existing results with the maximum absolute values of memristive connection weights, our ones are based on the average values of the maximum and minimum of the memristive connection weights. Finally, numerical simulations are given to validate the effectiveness of the theoretical results.  相似文献   

人格导入刑法研究     

杜菊  刘红 《保定学院学报》2011,24(5):55-59

审判实践引发了于定罪中是否要考虑人格问题的讨论。厘清人格的概念,分辨人格与人身危险性以及主观恶性的界限是解决这一问题的基础。从刑事立法以及司法的现实情况来看,在刑法中导入人格是必要的。作为发挥出罪功能的人格要素,应当归于犯罪主体要件,使平面化的犯罪主体要件鲜活起来,于定罪中发挥重要的作用。  相似文献

南社佚名诗人稿本的发现     

居疑 《寻根》2011,(3):86-88

前时孔网上有两册旧抄本拍卖,标价其实并不高,但以所上图片影影绰绰之故,连续四次（事后查询得知）上拍而无人问津。笔者略略看出一件似是诗抄,一件为文论,语涉近代史实,感觉其中应有些意思,待第四次流拍之后,跟拍主商价要下。购品收到,视其书法、纸张,  相似文献   

基于谱聚类的电压波动图谱一致性线变关系检测分析应用     

张自强  延亮 《科技通报》2021,37(5):48-51

基于谱聚类的电压波动图谱一致性线变关系检测分析应用是在电力物联网背景下,充分挖掘配网台区运行数据价值,通过大数据分析技术进行的探索和实践.根据"同一馈线下台区之间电压波动变化趋势一致"的原理,借助谱聚类分析技术,将月度1000万余条的电压运行数据,转换为"电压波动指纹图谱",构建基于谱聚类的电压波动图谱一致性线变关系检测模型,对同一馈线下台区电压时序数据进行波动一致性识别,输出馈线下电压波动明显异于其他台区的异动台区清单,为错误档案的系统化甄别提供快速、准确的分析结论,从大数据视角为检测线变异常关系提供全新手段.一方面切实有效的指导开展线变关系治理,进一步促进降低线损、落实基层减负;另一方面可为客户可靠供电和精准营销提供基础保障、改善客户体验;也为感知层和应用层提供坚实的数据质量监管提供手段.目前完成模型构建并持续优化,并现场试点验证,准确核实出27个线变拓扑关系问题.  相似文献

Library support for emergency management during the time of natural disasters: Through the lens of public library Twitter data     

Seungwon Yang  Boryung Ju 《Library & information science research》2021,43(1):101072

The public libraries in the Carolinas engaged with their communities using Twitter throughout the phases of Hurricane Florence in 2018. A total of 161 libraries in Carolinas were examined. The framework of crisis informatics, content analysis, and network analysis were applied to 738 Twitter posts from 17 libraries, which had Twitter presence, to understand interaction details between the libraries and communities that they serve. Findings include that the libraries shared a mixture of both disaster- and non-disaster-related information via their Twitter pages. The disaster-related tweets were mostly shared in the During (291 out of 349) and After (56 out of 349) phases. The number of general library-related tweets in the During phase dropped drastically compared to those in the Before or After phases. The libraries were also retweeting disaster-related tweets from various governmental agencies and NGOs to the community members in their social network. These findings indicate that the libraries switched their roles from a general services institution to an emergency information hub as the threat from the hurricane began affecting the communities. The knowledge gained from our study could be used to improve community resilience by further illuminating the role of public libraries as public infrastructures that host and facilitate the development of social capital during and after disaster events by becoming information and communication hubs.  相似文献
