The correction method use a 33 correction coefficients matrix to reshape the pulse width of each LED. To calculate the correction coefficients  a linear system is established  which includes a color CCD and a LED display. And a correction algorithm is introduced based on the color CCD. This algorithm describes the relationships of the main color components of a LED  when the gray level of a LED is increasing or decreasing  the three main color components would change according to the correction coefficients. The results shows that the correction based on this algorithm improved the performance of LED displays.

We analyzed the strongpoint and shortcoming of an information theoretic approach called minimum information loss method for model reduction. We explained relationships between the steady-state information entropy and controllability information for the Gaussian systems. The controllability  observability and Cross-Gramian information were analyzed in the time-domain. The frequency-domain Cross-Gramian information (FCGI) was defined based on Cross-Gramian matrix containing information associated with both controllability and observability. Furthermore  a valuable application of the frequency-domain Cross-Gramian information to model reduction (FCGMIL) was developed by using the concept and properties of frequency-domain Cross-Gramian information. The performance index of FCGMIL is to minimize the frequency-domain Cross-Gramian information loss caused by eliminating the state variables with weak contributions to Cross-Gramian information over some frequency band. Two numerical examples are illustrated to verify the efficiency of FCGMIL. 2010 IEEE.   Physical Organic Study of Structure-Activity-Enantioselectivity Relationships in Asymmetric Bifunctional Thiourea Catalysis: Hints for the Design of New Organocatalysts 期刊论文  OAI收割 CHEMISTRY-A EUROPEAN JOURNAL, 2010, 卷号: 16, 期号: 2, 页码: 450-455 作者:  Li, Xin;  Deng, Hui;  Zhang, Bo;  Li, Jiuyuan;  Zhang, Long   |  收藏  |  浏览/下载：8/0  |  提交时间：2019/04/09 Bifunctional Catalysis  Hydrogen Bonds  Linear Free Energy Relationships  Organocatalysis  Pk(a)
