  true signal
Fever originates by central nervous system activities, but neither exogenous nor endogenous pyrogens are able to cross the blood-brain barrier and the true signal which is transmitted to structures inside the blood-brain barrier is still unknown.
      
It is proved that the proposed estimator is asymptotically consistent and the estimated signal subspace is closer to the true signal subspace than the data signal subspace formed by MUSIC.
      
The true signal subspace is a subspace in the array manifold space.
      
Interpretation of the resulting retrievals will therefore rely on the facts that the satellite sampling will average the aliasing signal to some extent, and that the spatial patterns of aliased signal and true signal will be different.
      
Any chamber adulterates a true signal unless in the steady-state; therefore, a procedure for estimating an 'effective chamber volume' is presented which is an essential parameter for correcting a measured transient signal.

In Some case,we can know or estimate up the up-bound limiting the absulute value of rate of change in a true signal of time.It is possible to filter the in-put signal with noise by using this knowlege.We know it is natural to seek the tolution(out-put)which subjects to the restrictions and becomes nearest to input signal with noise in the sence of square error. Although,it is easy to reduce this problem to a special square programming problem,the computing based on general square progromming algorithm is ex- pensive and complex. In this paper,we propose a simpler algorithm with simpler compute-verson ndhigher speed.The data experiments demonstrate that,this algorithm is effective. After explicate the algorithm geometrically,we obtain the conditions on which a solution becomes a optimal solution,and the algorithm to find a opti- mal solution.

在有些情况下,我们知道真实信号变化率的绝对值的上限,或者知道它的估计值,利用这些,能够对带有噪声的信号进行非线性滤波。本文考虑的是求满足变化率约束条件下的与输入信号的平方距离最小的输出。这个问题是二次规划问题的一种特殊情况,但是利用二次规划的解法太复杂。本文建议的解法计算简单,并且从实验效果看,大部分噪声可以被消除。另外,在说明了该解法的几何意义之后,又讨论了最优解法的条件和算法。

A new fluorescent reagent, SPAEC, synthesized in our laboratory, has been used for determination of micro gallium and aluminum at optimal pH from 3. 8 or 4. 0 to 5. 5 with λex/λex being 515/580 or 535(520)/575 nm, respectively. When the two ions coexist, they will behave as a mutual interference. Kalman filter, an important tool of chemometrics, is a first order recursive optimal filter for estimating true signal in the presence of noise and an effective mathematical algorithm in data-processing of analytical...

A new fluorescent reagent, SPAEC, synthesized in our laboratory, has been used for determination of micro gallium and aluminum at optimal pH from 3. 8 or 4. 0 to 5. 5 with λex/λex being 515/580 or 535(520)/575 nm, respectively. When the two ions coexist, they will behave as a mutual interference. Kalman filter, an important tool of chemometrics, is a first order recursive optimal filter for estimating true signal in the presence of noise and an effective mathematical algorithm in data-processing of analytical chemistry. Kalman filtering spectrofluorimetry was applied to resolution of the overlapping fluorescence peaks of aluminum and gallium chelating with SPAEC at pH 4. 5 through some modes covering: (1) all peak scanning filtering, (2) selective scaning filtering and (3) sim-plized scanning filtering. The developed method was used for analysis of Al/Ga(1: 40-14 : 1) mixtures and considerably improved the selectivity of a high sensitive fluorimetric method showing a good prospect for trace analysis.

Satellite Laser Ranging(SLR) is one of the modern techniques to investigate the crust movements. For a station when one pass was observed, the first problem met is how to filter the true signals from the hundreds even thousands raw records as fast as possible. The method named deleting noises with interval-rate limitations, which was proposed by the paper, may solve the problem effectively. In addition, the method for estimating the single shot accuracy of a pass was also described in the paper. All the...

Satellite Laser Ranging(SLR) is one of the modern techniques to investigate the crust movements. For a station when one pass was observed, the first problem met is how to filter the true signals from the hundreds even thousands raw records as fast as possible. The method named deleting noises with interval-rate limitations, which was proposed by the paper, may solve the problem effectively. In addition, the method for estimating the single shot accuracy of a pass was also described in the paper. All the methods described in the paper have been used in Wuhan SLR station. We have sent our data to NASA GLTN since August 1989. The high percentage of using our data by Delft University of Technology, The Netherlands, shows that our method for processing SLR observations is reasonable, effective and reliable.
