The sub-filters of Interacting Multiple-Model algorithm are based on Kalman filtering, which requires the accurate statistical characteristics of noise. Unfortunately, it is usually unknown and only the approximative models can be obtained, which may result in decrease of IMM performance.

交互多模型算法的子滤波器都是基于Kalman滤波的，它要求知道精确的噪声统计特性，然而在许多情况下噪声信号的统计特性是未知的，只能得到噪声信号的近似模型，这在一定程度上降低了IMM算法的跟踪精度。

BLASTX analysis revealed that 47﹪ of the ESTs displayed the significant homology to functionally known or unknown genes from GenBank database. tBLASTx analysis suggested that 12 unisequences showed significant similarity to dbEST entries, of which 9 unisequences were from cDNA libraries of other biotrophic basidiomycetes.

Exact accuracy of these rifles is unknown, but i believe that those rifles will shot sub-1MOA groups with recommended ammunition 7.62mm NATO 168 grain (10.9 gramm boattail match ammo, like US M118 ball sniper ammo.

这些步枪精确的准确性是未知的，但我相信，这些步枪的射击分1MOA与建议弹药组（7.62毫米北约168粒（10.9格拉姆）boattail匹配的弹药如美国M118狙击弹药球）。

A robust output feedback controller is advanced by using the DRNN-based observer presented above, so that the output-matching and lipschitz conditions are not imposed on the uncertainties; Robust adaptive controller is used in a class of nonlinear systems based on neural networks and H〓 methods, thereby the constraint on uncertainties with largest known boundness is removed, not as in H〓 methods.

利用本文的动态神经网络鲁棒观测器，设计了鲁棒输出反馈控制器，取消了已有结果对未知动态的输出匹配条件的限制；结合静态神经网和H〓控制方法，对一类非线性系统设计了鲁棒自适应反馈控制器，克服了H〓控制要求不确定性最大可能界已知的不足，其最大优点是仅要求网络逼近误差有界，且不要求网络权的离线训练。

The databases of NIRDRS for Hypericum、 Eucalyptus globules and broussonetia papyrifera were established within suitable spectral ranges with three kinds of data block(original spectrum, first-order derivative spectrum and second-order derivative spectrum) to discriminate unknown samples.
