  target number
A median of one apheretic procedure (range 1-3) was required to achieve the target number of 6 × 106/kg CD34+ cells.
      
The core of the method consists in gathering random samples until a target number of redundant samples are obtained.
      
As was expected, the slopes for random and linear patterns were not so steep when the target number was low.
      
The subjects were asked to perform a same/different judgment, i.e., they were requested to decide whether a dot pattern, shown on a monitor, equalled a previously defined target number (n=2-6) or not.
      
RTs to these targets were longer and showed a steady increase in RT with target number, even in the subitization range.

In view of the echoes of in-coherent radar target being sensitive to its azimuth and time delay,this paper presents a neural network classifier (NNC) based on a prototype with multi-cluster, in accordance with the characteristics of vectors and templates obtained on the basis of the FFT-WAVELET-MELLIN (FWM) multi-transform and using the adaptivity and robustness of the neural network. By the available data it is proved that the described method may acquire satisfactory result with real-time in the recognition of airborne target number. Their classification and performance comparison are made among the NNC, BP classifier and normal N-neighbor classifier in this paper Also by analysing the classification experiment results of the three types of under water targets using this method, it is eventually proved that the presented method may find the prospect of a wide application.

In view of the drawback that conventional low-resolution radar can not directly resolve the targets flying in formation in both range and azimuth, an analysis is made of the difference of Doppler frequencies between two targets caused by their distance and the way in which the Doppler frequency varies. The possibility of distinguishing targets in time-frequency domain is investigated. A method of identifying the number of targets in formation is proposed on the basis of the image produced by the time-frequency distribution of their echoes and image description techniques. The experimental results of some real target echoes illustrate that the method can achieve a reliable identification of the targets number in formation, with certain capability of noise and interference rejection, less computational burden and easiness of real-time implementation, which is superior to conventional Radon transform.
