基于滑窗QR分解不但能快速、准确地更新正交投影,同时还可提供其协方差的rank-k更新表达,提出了一个用于信号子空间更新的快速PCA算法.通过对进行主元分析(PCA)计算的非线性迭代部分最小二乘算法(Non-linear Iterative Partial Least Squares,NIPALS)计算过程的改进,将特征向量的更新转化为小维度辅助向量的更新,在满足特征值和特征向量更新精度的同时,有效地提高了计算速度.将滑窗QR和快速PCA算法用于子空间辨识算法的自适应更新,数值仿真验证了此自适应子空间辨识算法的有效性.

Flood events are a recurrent threat to economic developments and can jeopardize human existence. In order to reduce the flood risks in Europe on a sustainable basis, the European Union adopted the Flood Risk Management Directive in 2007. The implementation of the directive in the national laws of all member states has laid the foundation for intergovernmental integrated flood risk management on an European scale. The following article is intended to compare and briefly assess the implementation process on inland waters at the technical level in selected European countries in the middle of the process. It covers the different basic structural, methodological, and data conditions for preparing the preliminary flood risk assessment, the flood hazard maps, the flood risk maps, and the flood risk management plans as a result of two EU projects. The technical differences in the various European countries need to be reduced in the next cycles of implementation of the Flood Risk Management Directive.

Necessary and sufficient conditions are obtained for the boundedness of Berezin transformation on Lebesgue space Lp(B,dVβ) in the real unit ball B in Rn. As an application, we prove that Gleason type problem is solvable in hyperbolic harmonic Bergman spaces. Furthermore we investigate the boundary behavior of the solutions of Gleason type problem.

The Changjiang River in China was dammed in 2003. The possible changes in matters fluxes from the river downstream after the completion of Three Gorges Dam and their potential impacts on the ecosystem of the East China Sea are discussed . The estuarine and coastal waters in the East China Sea were heavily fertilized by the inflow of nutrient-rich freshwater from the Changjiang River, which has led to severe eutrophication and frequent harmful algal blooms ,thus worsening the ecosystem health in this area. Analy- sis showed that the nutrient loadings are very likely to be reduced in the lower Changjiang River due to the construction of Three Gorges Dam. Especially for the total phosphorus, the discharges to the East China Sea will be reduced by one-third, which would relieve the severe eutrophication in this area. However, the expected decrease in the riverine silicate discharge would lead the ratio of silicon to nitrogen to be much less than 1 in the estuarine and coastal waters and thus may cause an elevation of flagellate growth. The changes in the annual water discharges and their seasonal distributions below the dam will be minor. Reduction of suspended particulate matter loading, due to the sedimentation behind the dam, will reduce the nutrient loadings of the particulate form especially for phosphorus, and decrease the turbidity of estuarine and coastal waters. On the other hand, this may enhance the erosion of the delta and the coasts as well as modifythe benthic ecosystem.

Many animals and plants have high potential to serve as concept generators for developing biomimetic materials and structures. We present some ideas based on structural and functional properties of plants and animals that led to the development of two types ofbiomimetic cable entry systems. Those systems have been realized on the level of functional demonstrators.
