守望春天

2004年12月22日，北京降下了这一年的首场大雪，整个北京城银装素裹。与此同时，人民大会堂里热气腾腾，中国室内设计学会成立15周年的庆典正在举行。作为个新型的学会，中国室内设计学会发展的进程紧紧跟随着我国改革开放和经济发展的步伐，我们用了二十年的时间达到了别的国家上百年时间才能达到的规模。中国室内设计学会已经逐步走入它的辉煌时代，正呈现着副朝气蓬勃的春天景象。

浅谈国企改革中的内部财务集中控制问题

一个完善的公司治理结构 ,应该是在明晰产权的基础上的三权 (决策权、监督权、经营权 )分立 ,各司其职 ,相互制衡的运行机制。财务总监委派制是近年来大型集团公司所实行的一种较有效的管理方式 ,是在企业财产所有权与经营权相分离情况下 ,集团公司通过委派财务总监参与企业重大经营决策 ,组织和监控企业日常财务活动 ,实现企业内部财务集中控制。使所有者及时获悉企业经营情况 ,确保了会计资料的真实性 ,提高了企业的竞争力     

我国车用无铅汽油的质量状况及分析

对1998－2001年间生产领域和流通领域的近500批次汽油产品检验数据进行了总结和分析，表明我国汽油的实物质量正在不断提高，但从环保要求出发还需不断向国际水平靠扰，尤其应进一步降低烯烃含量，硫含量。     

Feature Reduction via Generalized Uncorrelated Linear Discriminant Analysis

High-dimensional data appear in many applications of data mining, machine learning, and bioinformatics. Feature reduction is commonly applied as a preprocessing step to overcome the curse of dimensionality. Uncorrelated Linear Discriminant Analysis (ULDA) was recently proposed for feature reduction. The extracted features via ULDA were shown to be statistically uncorrelated, which is desirable for many applications. In this paper, an algorithm called ULDA/QR is proposed to simplify the previous implementation of ULDA. Then, the ULDA/GSVD algorithm is proposed, based on a novel optimization criterion, to address the singularity problem which occurs in undersampled problems, where the data dimension is larger than the sample size. The criterion used is the regularized version of the one in ULDA/QR. Surprisingly, our theoretical result shows that the solution to ULDA/GSVD is independent of the value of the regularization parameter. Experimental results on various types of data sets are reported to show the effectiveness of the proposed algorithm and to compare it with other commonly used feature reduction algorithms.     

Enhanced Oil Recovery: The Synthesis of Anthraquinone [1, 2-C] Alkylisoxazole

Anthraquinone [1, 2-C] methylisoxazole is synthesized from 2-ethylanthraquinone through nitration and treating with oleum. The different methods of 2-ethylanthraquinone nitrated were discussed. The optimum conditions were determined. The structure of the product was confirmed by MS and ¹H NMR.
