Chinese classical literature in Internet era from the perspective of data [PDF]

open access: yes, 2016
本文是将大数据方法应用于古典小说研究的尝试,在读者亦是用户的互联网时代,文学传播的媒介、方式、内容都发生了巨大的变化。随着电子阅读与网络浏览成为重要的文学接受方式,传统读者的评论过渡到网络用户的浏览、留言等,接受行为更加多元,这一系列的行为都在网络上留下痕迹,大数据技术对这些痕迹进行记录、存储、挖掘、分析,形成庞大的网络数据群。对这些数据进行分析,将成为文学研究的重要方法之一。另一方面,衍生品成为古典文学的重要传播方式。 本文分为四个部分,第一部分为研究综述,梳理国内外使用数据方法进行文学研究的状况 ...

Research on China's E-Government Information Resource Sharing Mechanism in the Era of Big Data [PDF]

open access: yes, 2016
随着现代信息通信技术的高速发展,人类迎来了大数据时代。数据已成为一项新兴的国家战略性资源,蕴含着巨大的经济价值和社会价值,引起全球各国政府极大的关注。大数据给我国政府工作带来了机遇和挑战。一方面,政府拥有海量的社会公共信息资源,通过整合、共享和开放,促进电子政务信息资源的开发和利用,能够加快推动政府职能转变,提升政府社会治理水平和公共服务能力;另一方面,由于种种主客观原因,我国电子政务信息资源共享机制尚不完善,制约了电子政务信息资源共享水平的提高,无法支持政府深入开展大数据分析和应用 ...

Local Ecological Knowledge Reveals the Distribution of Cryptic Nocturnal Wildlife 局域生态知识揭示隐秘夜行野生动物的分布

open access: yesWildlife Letters, EarlyView.
Many nocturnal animals are difficult to study because they are rarely seen, including nocturnal primates, galagos and pottos, in West Africa. Working with over 600 people in 52 villages in southern Guinea‐Bissau, we found that communities frequently recognized galagos by their red eyeshine and distinctive calls, while pottos were not known.

New oscillatory conditions of a class of the second-order Emden-Fowler differential equations(一类二阶Emden-Fowler 型微分方程的若干振动条件)

open access: yesZhejiang Daxue xuebao. Lixue ban, 2019
利用Riccati 变换技术,借助Bernoulli 不等式和Yang 不等式以及数学分析技巧,研究了具有非线性中立项的二阶广义Emden-Fowler 型微分方程的振动性,考虑非正则情形,建立了该方程的若干振动准则。最后用2 个例子说明,这些准则推广并改进了一些已有的结果,且具有较好的实用性和可操作性。

Big Data and Research of Big data in Modern Internet Aplications [PDF]

open access: yes, 2014
据Gartner研究表明,每天我们要产生2.5QB的数据,而在目前全世界的所有的数据中,90%的数据是近2年内产生的[1]。这些数据来之与各个不同的地方,例如传感器收集到的天气的数据[2],在社交媒体网站上的帖子[3],数码相片和录像,购物产生的交易数据[4],甚至手机GPS的信号产生的地理数据[5]。那么这些数据就是所谓的大数据。 随着全球的企业,政府组织开始认识到大数据的重要性,由机器传感器或者移动设备产生的数据以一个巨大的比例膨胀。有关机构预测在接下来的五年当中,这样的数据会增长超过650 ...

Movement and Space Use Patterns of the Beale's Eyed Turtle (Sacalia bealei) Suggest Sensitivity to Environmental Changes and Poaching 比氏眼斑龟 (Sacalia bealei) 的活动与空间利用模式揭示其对环境变化及盗猎的敏感性

open access: yesWildlife Letters, EarlyView.
Using radiotelemetry, we found that the movement and home range of the endangered Sacalia bealei varied significantly across reproductive classes and seasons, with males exhibiting greater movement than females during wet and mating seasons. The species exhibits strong aquatic dependence, favoring deep pools interspaced among riffle‐pool sequences ...

Individual Variation in Overwintering Strategies of the Great Evening Bat (Ia io) in Subtropical China 中国亚热带地区大足蝠 (Ia io) 越冬策略的个体差异

open access: yesWildlife Letters, EarlyView.
Tracking with GPS and accelerometers shows that great evening bats in subtropical China use two overwintering strategies: some remain in continuous hibernation, while others switch between torpor and activity as temperatures change. This behavioral flexibility, shaped by climate, underscores the importance of protecting diverse roosting habitats for ...

New lower bounds for the minimum eigenvalue of the Hadamard product of nonsingular M-matrices(非奇异M-矩阵Hadamard积的最小特征值的新下界)

open access: yesZhejiang Daxue xuebao. Lixue ban, 2017
针对非奇异M-矩阵B与非奇异M-矩阵A的逆矩阵A-1的Hadamard积的最小特征值τ(B◦A-1)的估计问题,首先利用矩阵A的元素给出A-1各元素的上下界序列,然后利用这些序列和Brauer定理给出τ(B◦A-1)单调递增收敛的下界序列.最后,通过数值算例验证理论结果,显示所得下界序列比现有结果精确,且能收敛到真值.
