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.

中日刑事强制措施制度之比较

刑事强制措施是刑事程序法的重要组成部分。但自1996年修改《刑事诉讼法》至今，由于立法观念及技术等方面的原因，刑事强制措施在立法和司法实践中暴露出许多问题。故从比较法的角度，对日本的刑事强制措施制度和我国的法制现状进行分析比较。并从我国司法实践出发，对刑事强制措施的改进提出若干建议。

An Improved S-Random Interleaver Design for Turbo Code Based on Chaos Model

A new method to design interleaver based on Henon chaos model is presented. The designed interleaver is with rather random behavior. Experimental results show that the proposed S-henon interleaver make a magnitude of im provement in bit error rate （BER） performance by 0.4 dB compared with the S-random interleaver for AWGN channel respectively. The S-henon interleaver may be adapted to 3G mobile communication systems.     

数据包络模型的随机性研究

利用最小绝对误差估计和机会约束规划，本文研究了数据包络模型中的随机性问题，建立了一系列线性与非线性规划的数据包络模型。并对模型解的存在和鲁棒性作了讨论。     

一种测试圆度的新算法

轴承的外圆环、内圆环是否圆以及圆的程度如何,都会对使用轴承的机械设备产生很大的影响,但是它们是否圆,靠肉眼是很难观察出来的,我们只能用仪器进行测量,假设仪器测量的结果是准确的或者误差是确定的,由于算法不合理,可能本来是圆的但得到的结果却是不圆的,这样就把本来是合格的产品当作废品处理了,这是不应该出现的问题,本文提供了一种新的算法来解决此问题.
