图像分割的自适应K均值聚类算法研究

使用K均值聚类算法完成对图像的分割是一种常见的分割技术,针对传统的K均值聚类算法的不足,提出了使用直方图波形的有效波峰个数自适应确定K值的大小,实验结果表明,该方法简单、灵活、容易实现,并能取得较好的结果。     

辐射板强化喷管换热与红外抑制效果试验研究

试验研究了在发动机喷管中加装金属辐射板前后,喷管壁面温度、热喷流温度与喷管红外辐射特征的变化。结果表明,加装金属辐射板后,热喷流与喷管壁面之间的热量传递显著增强,热喷流中心温度降低,壁面温度明显升高,在90°方向上,热喷流3～5μm波段的红外辐射强度降低了38.5%。文中从热喷流、喷管壁面以及金属辐射板等相关部件的温度变化情况对红外辐射强度的变化原因进行了解释。      

Image Repair on the Donald Trump “Access Hollywood” Video: “Grab Them by the P*ssy”

In October 2016, Donald Trump was in the midst of a hotly contested and sharply divisive presidential campaign. Days before the second presidential debate, The Washington Post posted a video of Trump “having extremely lewd conversation about women in 2005.” This video and the firestorm of criticism it provoked threatened to derail his presidential run. Mr. Trump and his wife Melania Trump offered several messages to repair his damaged image. This article analyzes and evaluates these image repair messages concerning Donald Trump’s “Access Hollywood” video. In such a divisive context, the defense had no hope of repairing Trump’s image with the general public (Trump lost the popular vote by 2.9 million). Even though he lost the popular vote, the business magnate won the Electoral College. We cannot say that the “Access Hollywood” video was solely responsible for Trump’s poor popular vote showing, but it is clear that this defense did not completely dispel the cloud surrounding him.

基于照片的抽象线条画生成

绘画作品以其鲜明的表达方式常常能给观众留下深刻的印象。但其对创作者的高要求使普通大众难以得心应手的自己进行创作。随着科学技术的发展,基于数码照片对各种绘画风格进行模拟成为了非真实感图形学研究的热点。本文在总结前人研究成果的基础上,结合尺度空间理论和边缘检测技术,提出了一种基于照片生成抽象线条画的方法。通过实验证明,本方法能较好的模拟线条画的主要特点。     

Social support and digital inequality: Does Internet use magnify or mitigate traditional inequities in support availability?

This study tested competing predictions about the implications of Internet use for traditional inequities in social support availability. Using survey data collected as part of the Pew Internet and American Life Project, inequities in social support availability stemming from demographic and network-related factors were examined among non-users, Internet users, and Internet users who also participated in a social network site (SNS). The results offered evidence consistent with the social compensation perspective. Traditional inequities in support availability related to age, race, and total network size persisted among respondents who did not use the Internet, but were less evident or absent among Internet users and/or Internet users who participated in an SNS. Using the Internet to connect with others appeared to be an important mechanism through which inequality in support availability was mitigated.     

第三方物流企业客户忠诚度评价及提升

随着第三方物流行业竞争的日益激烈,评价及提升客户忠诚度已成为企业发展的重要问题。对客户忠诚度可从客户满意、转换成本、关系信任、重复购买、客户推荐、交叉购买、价格敏感等方面进行评价并建立相应的测量指标体系,又可从提高客户满意度、对企业的信任度以及转换成本等方面提升客户的忠诚度。     

论体育教师的新形象——从行政管理学之领导者的素质和艺术的角度

我国处于体育教学摸索初期,改革是必不可少的环节。现代体育教师如何在未知的改革中站稳脚步,同时又要用自己的表现改变人们对体育教师的不认可态度。本文采用文献资料等方法,通过对管理学、行政管理学与体育学等学科的糅合角度出发,指出现代体育教师新形象的确立需要的素质以及更为重要的处事艺术,对促进体育在社会中的认识度和承认度有不可估量的作用。     

MATLAB图像处理技术计算棉纤维成熟度比的探讨
