Explicit and Iterative Methods for Solving the Matrix Equation AV + BW = EVF + C

In this paper, we consider explicit and iterative methods for solving the Generalized Sylvester matrix equation AV + BW = EVF + C. Based on the use of Kronecker map and Sylvester sum some lemmas and theorems are stated and proved where explicit and iterative solutions are obtained. The proposed methods are illustrated by numerical example. The obtained results show that the methods are very neat and efficient.     

Uppsala Creativity Day, 2 March 2009

中国多媒体技术研究：2009

本文是中国多媒体技术研究与应用的年度文献综述之十二。该文从2009年9种核心刊物的3023篇中选取396篇多媒体技术相关的文章进行了分类、统计,以展现出2009年中国多媒体技术发展的现状。今年采用的分类方案在去年的基础上做了一些调整,以适应多媒体技术发展的趋势。通过与前4年统计结果的对比可以看出,数字水印、数据管理与检索、多播、交互模式与接口、虚拟现实交互等多媒体基础技术是2009年论文反映出的研究热点,同时,多媒体应用日趋多样化,与社会生活的结合程度越来越紧密。该文还对近5年的中国多媒体技术文献统计结果作了比较,从中可看到多媒体技术,特别是一些热点技术的发展趋势。该文不仅能给从事多媒体技术研究与应用的人员提供系统的文献索引,也能为技术规划和管理人员提供参考。

寄语2009

<正>窗外阳光明媚,气温却被冷冽的寒风定格在零度以下。这就是冬天的个性,它让人们充满对温暖的想象,却又毫不留情地将寒意灌进人们的衣领。
