自跟踪

Results: Follow-up ob servation of living cells revealed that upon the Ti disc there were cells migra ting from the cellular layer and attaching to the rim of it, forming cells bridg es between them, and then more cells were found to attach and orient as the cult ure went on.

结果：活细胞跟踪观察揭示钛片放入细胞层表面后即有细胞自细胞层表面向钛片侧壁移行、贴附，并在二者之间形成细胞桥。

A robust adaptive control scheme was proposed for a class of nonlinear systems in the presence of unknown parameters and unmodeled dynamics. The whole design was divided into two steps.

针对一类含有不确定参数和未知扰动的非线性系统，提出一种鲁棒自适应控制方法以确保系统输出稳定地精确跟踪给定的参考信号。

This paper introduces an adaptive practical output tracking control algorithm for inverted pendulum which is a nonlinearly parameterized system with unmodeled dynamics.

In this paper,a new variable structure robust model reference adaptive control scheme is proposed,which deals with a class of SISO plants under parameter and unmodelled dynamical uncertainties.It is shown that even with the existence of unmodelled dynamics,the output tracking error will converge to zero in finite time, and the SPRcondition for reference model is not required.

摘 要 讨论了含结构不确定SISO系统的变结构模型参考鲁棒自适应控制问题，提出了一种新的变结构控制方法，使得：1系统在同时含参数及结构不确定性时，跟踪误差仍能在有限时间内收敛到零；2无须假设参考模型为SPR函数。

The vision recognition is processed with two stages. In the first stage, a grid search scanning from top to bottom and left to right is processing to find an object point inside an unrecognizing object, then a precision analyzing and recognizing procedure based on object region projection is processing for determining the robots and football's position and also the robots' orientation in the second stage.

首先对于由CCD镜头所捕获的图像进行宏观位置跟踪，即自上而下、自左至右地进行网格搜索，获取目标物体内一点；然后从该点出发，利用区域投影，对目标物体精确定位，得到小球和各机器人的中心位置及各机器人的方位。

This method sorts color of object unsupervisedly in the HIS space using the approach of growing, pruning and merging clusters. The approach keeps an appropriate clustering number for accurate object tracking.

通过在色度、饱和度、亮度HSI(hue， saturation， illumination)空间自组织非监督地进行颜色聚类，使用增加、削减和融合聚类的方法，寻找适当的聚类数量，使目标跟踪更加精确。

Cases with renal transplantation were performed with dynamic state CDFIin Ultrasound Dept. of Nan fang Hospital from April, 2005 to October, 2006. Theexamine time is respectively after operation in three days, seven days, one month andthree months. Before operation examine the condition of uropoiesis function such as apair of kidney, ureter, bladder and cardiac function. After operation reexamine thecondition of cardiac function once again, and examine TK detailed and completely:First, using two-dimensional imaging to observe the shape and the volume of the TK.Secondly, using Color Doppler to observe the renal artery and each artery inside theTK. Finally, using pulsed Doppler to measure the peak systolic velocity, enddiastolic velocity and resistance index.

对南方医科大学南方医院超声诊断科自2005年4月～2006年10月对152例同种异体肾移植患者进行动态CDFI监测，超声检查时间分别为术前与术后3d、术后7d、1个月及术后3个月，术前超声检查双肾、输尿管、膀胱等泌尿系功能情况及心脏功能情况，肾移植术后再次对心脏功能情况进行跟踪复查，并对移植肾进行详尽检查：先用二维超声观察移植肾的形态、大小，随后应用CDFI观察移植肾动脉及肾内各级动脉的血流充盈情况，最后用脉冲式多普勒测量收缩期峰值流速、舒张末期流速、阻力指数。

As she looked at Warrington's manly face, and dark, melancholy eyes, she had settled in her mind that he must have been the victim of an unhappy attachment.

每逢看到沃林顿那刚毅的脸，那乌黑、忧郁的眼睛，她便会相信，他一定作过不幸的爱情的受害者。

Maybe they'll disappear into a pothole.

也许他们将在壶穴里消失
