沈彬：“铁路实名制”为谁服务？

原题：只为“管理”不为“服务”的铁路实名制

来源：新快报 2011年8月9日 星期二

今年6月1日起，全国铁路动车组统一实行实名制，但据新快报记者亲身亲历，目前的“实名制”却没有发挥之前大家料想的作用——售票窗口不核对身份证，张冠李戴照样买到车票。上车只查车票，不查身份证。车票如果遗失，也不能够补票，甚至还要从列车始发站补起。铁路检票员的解释是：系统中根本查询不到乘客信息。

公众的想法很简单，既然动车购票是实名制的，铁路就已经掌握了乘客的信息，身份是确定的，那么为什么不能像飞机那样实现补票功能呢？或者直接在火车站用身份证换

 经过整理，部分同学的选题发生了变化，但是基本上都只在本人选题的类别中更改，尽量选择了和原选题研究内容相近的题目，请同学们就本选题先期查阅资料，以便了解本题的研究现状及研究内容和方法。

  昨晚离开家之前同女儿再见，乖女儿很不情愿的跑过来，拉着我的手说：“爸爸，不要出去，和苗苗玩儿！”在得知爸爸必须离开以后，坐在地板上低着头待了一会儿，才抬起头来，撅着小嘴和爸爸吻别.......唉，女儿懂事了，心里真不是滋味啊，真想天天陪着她成长。

上传照片才发现，1，2月和女儿的合

ANother year gone,I need to work harder for more。。。。

管理学院真是人才济济啊，这件事情真的很难》。。。。。眼看着机会就这样溜走，只能怪自己没本事啊，神啊，求求你赐予我力量吧

这是在医院里我和女儿的第一张合影，辛苦的一个月啊

那时的小脑袋还可以捏在手里，洗头时一只手就可以把两个小耳朵捏住，免得进水....现在不行喽！

趴在我身上安静的进入梦乡，我就这样斜靠在床边

A Pseudo-parallelism Genetic algorithm Framework to optimization of Neural Networks

Abstract—This paper present a new approach, combined Pseudo-parallelism evolution technique based on sub-population competition with parent mutation mechanism, for automatic topology optimization of Multi-layer Feedforward Neural Networks. It allows that two networks with different number of individuals can be crossed to a new valid ”child” network. The calculation result of an example shows that PPGA is able to get the real-time information of population diversity during the process of evolution and has some improvements in both global converging velocity and searching precision.

A General Overview of B-P Neural Network Applications in Mobile Agent-Based E-commerce Model

Abstract：Electronic commerce model on mobile agent-based can provide characterizing services to consumers and companies, such as supply chain management, commodity exchanging and electric auctioning in the virtual market in the cyberspace. This paper overviews a large body of literature  on this subject and shows the state of the art of combining the neural network and electronic commerce model together. After introduced the basic theory of B-P neural networks, the application of neural networks in this kind of model has been analyzed, such as route selection, commodity agent, merchant negotiation and system security etc.
