Orthogonal testing method is used to optimize nitrogen source in fermentation culture medium of B.subtilis24A1/pMX45, and engineering average estimation method is used to estimate the range of riboflavin production.
The great significant and significant technology parameters and the optimized technology are defined by analysis of variance, An engineering average estimation is made for the optimized technology, and the quatily level and gains of the optimized technology are calculated.
The paper presents a novel adaptive harmonic detecting algorithm using the coherence average estimation of K(n)to control the updating of the step size,where K(n)is the proportion of the error signal e(n)in the total signal S(n).
Truong and Stone considered the local average estimator of regression function based on stationary and mixed time series in [1], and proposed an open problem that can the condition 4(ii) in [1] be weaken. In this paper, we give a positive answer.
According to the average estimator of technical efficiency we investigate the overall efficiency trend of the state-owned commercial banks, and conclude that the technical efficiency of Chinese state-owned commercial banks is very low during the periods of Asian finance crisis, as accords with the facts of the time;
T(n,e,α)=T(p,q,e,α) denoting the number of α-oder fixed points of RSA(p,q,e) , one kind of estimation on logT(p,q,e,α) is gived, when e runs over a set.
Coeffi-cient of correlation、slope and standard error of estimate were 0.820 (p<0.01)、1.292and 6.7w (8.6%),respectively. This slope was statistically not different from that forgroup 1 (1.001).
These results show that this algorithm can realize 0 of bias mean value and 0.12～0.15 of root of mean square in 40 μs,and can also improve BER of the communication system.
Testing the new model for radiometric measurements showed that the average estimation error for 10 varieties under early rice conditions was less than 1%.
The average estimation error from patient data loop control of nine patient treatments.
The average estimation error from patient data analysis of 21 sites at which temperature was independently measured (three per patient) was 0·0°C, with a standard deviation of 0·8°C.
The average estimation errors were 7% and 9% when two and three synthetic radiographic images obtained at different x-ray tube settings were used.
An extension of this multi-point conditional average estimation is presented in this paper in the form of a pseudo-dynamic reconstruction of the flow field.
The estimate of mean weight-specific daily growth (0.12?day-1) is lower than that of other species in the area, but it is consistent with a slower development rate.
It was concluded that a site midway between the umbilicus and a nipple yields a more accurate estimate of mean torso temperature in the conditions of the present study.
A crown deformation ratio, D, gave a good estimate of mean windflow in complex terrain.
A compression index, C, describing tree-ring asymmetry, gave a reasonably good estimate of mean wind flow over flat terrain but was unreliable for estimating wind flow over hilly terrain.
As a demonstration of the stable accuracy of the temperature sensors, the poorly resolved records provided an estimate of mean stratification to within 5% of the estimate using Seabird CTD data.
In particular, the precision of the moving average estimator (MAE) and the best linear unbiased estimator (BLUE) for genotypic values in mass selection were compared.
For the first test we measured the dependence of the performance of the moving average estimator on the window size.
Hence for homogeneous sampling, the average estimator from Section 2.3 is the minimum variance convex combination of the Xj.
If all estimated variances are zero, use the average estimator.
On the other hand, the average estimator is susceptible to the effect of high variances.
Burg's maximum entropy spectral estimation method has defects of spectral peak shifting and line splitting, which are mainly due to the biased estimation p1 to the first reflection coefficient and the biased estimation to the expectation value of the time series with non-ergodicity implied in short sample records. Aiming to these two causes, the authors suggest two improved algorithms of Burg's method. The simulation computations show that the results are remarkablly good.
Based upon intensity and acceleration data obtained during the Tangshan earthquake and from other earthquakes, attenuation relationships of ground motion acceleration and response spectrum for North China were reduced for rock sites, on the assumption that same intensity corresponds to same acceleration only when the magnitude of earthquake is the same. Some shortcomings of the acceleration attenuation directly from intensity-acceleration conversion were also pointed out for the first time, i. e. the acceleration...
Based upon intensity and acceleration data obtained during the Tangshan earthquake and from other earthquakes, attenuation relationships of ground motion acceleration and response spectrum for North China were reduced for rock sites, on the assumption that same intensity corresponds to same acceleration only when the magnitude of earthquake is the same. Some shortcomings of the acceleration attenuation directly from intensity-acceleration conversion were also pointed out for the first time, i. e. the acceleration attenuation obtained is the envelop estimate, not the mean, and the variance is too much underestimated.
