气韵理论视野下的敦煌壁画探微     

刘玉敏 《蒙自师范高等专科学校学报》2010,8(3):107-109

"气韵生动"是我国传统绘画的最高审美追求,这种审美追求自然会带到敦煌壁画的创作中。敦煌壁画的艺术风格具有传神技巧的丰富性,"中国化"的韵致体认,动态感的境界渲染和"天人合一"的精神旨归等特点。  相似文献   

基于嵌入式系统移动物联网系统研究与实现     

王金矿  张晶  李世兴  李杰伦 《广东广播电视大学学报》2013,(6):32-35

基于RFID技术的移动物联网应用已比较广泛,RFID技术最大缺陷是信息的单向传输。解决移动物体的信息双向传输,实现具有普遍意义的移动物联网需要解决三个层面的问题-感知层、网络层和应用层。选择嵌入式系统作为控制单元,通过在移动物体上控制单元建立WIFI热点解决网络层问题,应用层则通过将移动物体控制单元设置为wleb服务器实现。  相似文献   

汉日主语位移现象比较     

邵小丽  李雪华 《洛阳师范学院学报》2013,32(7):126-128

主语的位移现象在日语和汉语中都有出现,但二者是有区别的,汉语主语具有"前移"和"后移"两种情况,而日语主语位移只有"后移"一种情况;从位移定义要素上看,汉日语发生位移的主语都可以原样回到原来的位置而意义不变,并且句子的表达重心在前移成分上;从形式上看,汉日语移动后的主语与陈述部分之间一般有适当停顿,书面上用逗号隔开,口语上有一定的语音停顿,且语句重音在前移部分上,后移部分轻读;在形式标志上,日语中充当主语的词汇或词组一般都要后加"が""は""の""も"等表示主格的助词或副助词,汉语中的主语同谓语的关系主要由语序来决定,主语大都相对固定在句首。但无论是汉语还是日语,句末语气词都不会出现在后半部分,而是紧跟在前移部分之后。  相似文献   

贵州穿青人族属考析——与畲族同出古帝少昊   总被引：1，自引：0，他引：1  

黄锦树 《韩山师范学院学报》2013,(1):21-29

穿青人是东夷太昊、少昊和蚩尤三部落联盟中奉鸟为图腾的嬴姓少昊苗裔。二昊、蚩尤在涿鹿败于黄炎帝部落联盟后,其南迁三苗裔（至迟于尧时已南迁岭南）,又继前三古帝联盟,奉出自龙图腾的太昊裔盘瓠为总领（王）。后来,三苗又演变为瑶、畲、苗三族,穿青人即归属汉初建立南海王国的畲族。  相似文献   

基于因子分析和曲线拟合的集装箱吞吐量预测     

贾飞跃  韩晓龙 《上海海事大学学报》2019,40(2):18-22

为提高集装箱吞吐量的预测精度,提出基于因子分析和曲线拟合的集装箱吞吐量预测模型。以上海港为例,通过因子分析,分析影响集装箱吞吐量的主要因素,筛选出主因子,得到不同年份的综合经济发展值;再运用曲线拟合方法,建立以综合经济发展值为自变量,以集装箱吞吐量为因变量的三次曲线模型;运用自回归积分移动平均(autoregressive integrated moving average,ARIMA)模型预测2016—2020年的综合经济发展值,进而求得2016—2020年上海港集装箱吞吐量预测值。结果表明:该模型的拟合效果和预测精度均较高,可以运用到集装箱吞吐量预测中。给出上海港在国内经济新常态下转型升级的建议。  相似文献   

Impact of combining data from multiple instruments on performance of patient-based real-time quality control     

Qianqian Zhou  Tze Ping Loh  Tony Badrick  Chun Yee Lim 《Biochemia medica : ?asopis Hrvatskoga dru?tva medicinskih biokemi?ara / HDMB》2021,31(2)

IntroductionIt is unclear what is the best strategy for applying patient-based real-time quality control (PBRTQC) algorithm in the presence of multiple instruments. This simulation study compared the error detection capability of applying PBRTQC algorithms for instruments individually and in combination using serum sodium as an example.Materials and methodsFour sets of random serum sodium measurements were generated with differing means and standard deviations to represent four simulated instruments. Moving median with winsorization was selected as the PBRTQC algorithm. The PBRTQC parameters (block size and control limits) were optimized and applied to the four simulated laboratory data sets individually and in combination.ResultsWhen the PBRTQC algorithm were individually optimized and applied to the data of the individual simulated instruments, it was able to detect bias several folds faster than when they were combined. Similarly, the individually applied algorithms had perfect error detection rates across different magnitudes of bias, whereas the error detection rates of the algorithm applied on the combined data missed smaller biases. The performance of the individually applied PBRTQC algorithm performed more consistently among the simulated instruments compared to when the data were combined.DiscussionWhile combining data from different instruments can increase the data stream and hence, increase the speed of error detection, it may widen the control limits and compromising the probability of error detection. The presence of multiple instruments in the data stream may dilute the effect of the error when it only affects a selected instrument.  相似文献   

Engagement with news on Twitter: insights from Australia and Korea     

Robert Ackland  Mathieu O’Neil  Sora Park 《亚洲交流杂志》2019,29(3):235-251

ABSTRACT

This study examines the patterns of news engagement among news consumers with different political affiliation and cultural background. We use computational methods and data from Twitter in a cross-country comparison of engagement with six online news sources in Australia and South Korea. For our analysis, we used a subset of Twitter users who retweeted at least one political story during the period of collection, and for whom we were able to predict political affiliation using correspondence analysis and data on Twitter follower ties to politicians. We find that right-wing Australian retweeters are more intense in their news engagement, compared with their left-wing counterparts, whereas in South Korea it was the opposite. Australian right-wing political retweeters have more diverse information sources, while there was no difference in information diversity between the right and left in South Korea. We discuss how the political situation in South Korea at the time of data collection may have affected our analysis. We emphasise the methodological contributions of our research and its connection to on-going research into the behavioural foundations of ‘filter bubbles’.  相似文献

《望天门山》别解     

陈立正 《甘肃高师学报》2008,13(4):24-25

李白七绝诗《望天门山》历代学者解释众说纷纭,莫衷一是,尤其是关于作者观察景物的立足点问题,直接关系到对全诗思想内容和艺术特色的分析理解,但是各家版本表述不一,造成对于诗歌理解的偏差甚至谬误。因此就这一关键问题,对比各家注释差异,进行较为深入的分析,认为作者的立足点为沿长江顺流东下,远远望见天山门一带壮观的景象,从而写下这首千古传诵的名篇。  相似文献
