1中文文本压缩的LZW算法显示文摘本文报告两个关于中文信息处理研究的结果:(1)采用Cover的方法,猜估中文信息熵,实验表明,中文信良熵不大于4.1bits/字。(2)根据中文的结构特性,选择Welch型的Lemple-Ziv数据压缩算法,把它移植、扩展于中文文本压缩上。应用该算法于不同类型的中文文本,本文获得一些中文文本压缩实际性能值。徐秉铮 吴立忠 Victor K.Wei 1989华南理工大学学报(自然科学版)1989,17,3:6

4Sensitivity improvement of broadband electro-optic polymer-based optical phase modulator using 1D and 2D photonic crystal structures显示文摘This Letter introduces the design and simulation of a microstrip-line-based electro-optic(EO) polymer optical phase modulator(PM) that is further enhanced by the addition of photonic crystal(PhC) structures that are in close proximity to the optical core. The slow-wave PhC structure is designed for two different material configurations and placed in the modulator as a superstrate to the optical core; simulation results are depicted for both1 D and 2D PhC structures. The PM characteristics are modeled using a combination of the finite element method and the optical beam propagation method in both the RF and optical domains, respectively.The phase-shift simulation results show a factor of 1.7 increase in an effective EO coefficient(120 pm/V) while maintaining a broadband bandwidth of 40 GHz.K.Receveur K.Wei M.Hadjloum M.El Gibari A.De Rossi H.W.Li A.S.Daryoush 2017Chinese Optics Letters2017,15,1:0
