非寿险投资型保险产品开发的经验、问题和对策——从资金运用角度出发的思考

非寿险投资型产品是带有投资性质的非寿险保险产品.现阶段,大力发展非寿险投资型产品是满足多样化金融需求,做大做强非寿险业的客观需要.目前,我国非寿险投资型产品起步晚,规模小,发展很不充分.针对发展过程中的经验教训和出现的问题,应从增加资金运用透明度、提高资金运用专业化、创新产品开发机制等方面采取措施,促进非寿险投资型产品迅速发展.     

Weight measurement using image-based pose analysis

Image-based gait analysis as a means of biometric identification has attracted much research attention. Most of the existing methods focus on human identification, posture analysis and movement tracking. There have been few investigations on measuring the carried load based on the carrier＇s gait characteristics by automatic image processing. Nevertheless, this measurement is very useful in a number of applications, such as the study of the carried load on the postural development of children and adolescence. In this paper, we investigate how to automatically estimate the carried weight from a sequence of images. We present a method to extract human gait silhouette based on an observation that humans tend to minimize the energy during motion. We compute several angles of body leaning and determine the relationship of the carried weight, the leaning angles and the centroid location according to a human kinetic study. Our weight determination method has been verified successfully by experiments.

Women''''s Vocabulary——Different Languages for Different Sexes

Sex differences are a fundamental fact of human life and it is not surprising to find them reflected in language.It's said that women tend to use more standard forms of English,while men tend to use less standard forms of English.Over the past thirty years,and as a result of the women's movement,gender issues have become entangled with issues of language.Recent research indicates that sex may be more fundamental as an influence on sociolinguistic variation than has been recognized so far.This article will try to discuss the different language use between men and women.     

扩展Meadows模型分析Ad Hoc网络路由协议安全性

目前,Ad hoc网络安全路由协议缺乏有效的形式化分析方法.通过添加基于图论的路由描述和分析方法,文章扩展了Meadows模型的分析能力.使用扩展后的Meadows模型对Ad hoc网络安全路由协议Ariadne进行了分析,分析结果显示Ariadne协议存在产生虚假路由的漏洞,从而也说明了扩展后的Meadows模型能够用于Ad hoc网络安全路由协议的安全性分析.
