The innovative idea of the method is in that the analytic ability for high - frequency signals of wavelet packet is used to enhance information capacity . because the human vision is insensitive to high - frequency signals , one can make information of watermark mass and hightensile in the high - frequency domain . in this way , not only the quality of original image can be reserved , but also the robustness of the watermark improved 其创新点就在于利用小波包对高频信号进一步分解的能力，极大地拓展了信息嵌入的空间，由于人眼视觉对高频信号的不敏感性，可以以较大的强度在高频部分嵌入水印，这样不但可以保证原图质量，而且可以进?步提高水印的顽健性。
Because die common fault detection method for sensors , residual x2 test , is insensitive to gradual - change - fault detection , a kind of residual x 2 test based on moving subnormal state is presented , and its validity is testified by mathematical simulation results , as shown in figures 5 . 2 through 5 . 5 . with regard to the lag of soft fault detection , a kind of system reconstruction tactic based on hierarchic alliance structure of federal filters is proposed . mathematical simulation results , as shown in figure 6 . 10 , show the validity of isolating fault by using the tactic 西北工业大学沁士学位论文们要一个研究指出常用的传感器故障检测方法?一残差x ‘检验法对渐变性故障检测的不敏感性，提出一种基于移动伪正常状态的残差检验法，并通过数学仿真验证该方法对渐变性故障检测的有效性；提出一种基于递阶联合滤波器结构的系统重构策略，并通过数学仿真验证该策略对故障隔离的有效性。
Based on a reduced - order model , the vsc of flexible rotor - magnetic bearing system is also investigated . a master - slave controller composed of a pc586 and a tms320c50 dsp board is build and a flexible rotor - magnetic bearing test rig is developed . simulation and experimental results show that the vsc is insensitive to the spillover problem due to the model truncation and parameter uncertainty 结果表明,变结构控制器对于因模态截断及非并置问题导致的未建模动态以及因系统自身特性变化而导致的参数摄动具有不敏感性,系统在上浮过程、受到外界扰动及复杂运转情况下的性能均优于pid控制器。
Whereas their parent mutant axr1 - 3 was male fertile , showed moderate insensitivity to ja - inhibitory root growth and mild reduction of ja - inducible gene expression ; parent mutant coi1 - 2 - was a leaky mutant allele of coi ! , it exhibited reduced ja insensitivity and partial fertility . - taken together , all these results suggested that scfcoil complex was required for the ja response and that the axr1 - dependent rubl modification of atcull subunit of scfcol " was important for ja signaling in arabidopsis 试验结果发现， coil 2 axrl 3双突变体在根的生长、茉莉素诱导基因的表达和雄性育性方面对茉莉素都表现为完全抗性；而亲本coil 2和axrl三突变体对茉莉素均表现部分不敏感性，表明axr基因和coil基因的同时突变协同增强拟南芥对莱莉素的不敏感性， axr基因与coi基因相互作用调控茉莉素的信号传导途径。
The complex resonance frequency underlying in late - time scattering components of a conducting target is independent of waveform and polarization of the incident wave , as well as the direction of the target relative to radar . it is a unique aspect independent quantity so far used to characterize target physical structure and component 目标的后时响应中包含的自然谐振频率成分(极点) ,不依赖于雷达发射电磁波波形、和其极化形式,与目标对雷达的取向无关,具有目标姿态不敏感性。
The main study includes the following contents . in this thesis , we present a method to pose variant face recognition that combines two recent advances : component - based face recognition and 3d mophable model . in this method , 3d components is robust to pose changes and are extracted as the input feature to face recognition 本文基于三维形变模型,针对多姿态人脸识别问题,主要做了以下几方面的工作:提出了一种基于三维部件技术的多姿态人脸识别方法,该方法根据面部部件对姿态变化的不敏感性,利用部件的三维信息作为特征进行人脸识别。
