The proposed method first uses common subtractive clustering locating method to acquire video object position and moving object number of each frame. Then, the proposed algorithm uses fuzzy C-means clustering algorithm to further cluster the moving object foreground pixel samples. Finally, matrix analysis theory for calculating eigenvalues and eigenvectors of covariance matrix is applied to compute the object scale and orientation parameters.

该算法在减法聚类算法预定位目标位置及获得目标个数的基础上，进一步采用模糊C均值聚类对目标前景样本进行归类，最后通过对目标前景样本协方差矩阵特征值和特征向量的分析获得目标的尺度及方向参数，从而实现对视频运动目标的定位。

On the basic theory, some concepts are proposed, such as partial derivative of waveform polynomial, waveform polynomial vector, delay matrix, multiple valued Boolean process, conditional sensitization, waveform distance with crosstalk and three-dimentional Boolean process. And based on these concepts, a sensitization theorem for sequential circuits and the transition numbers theorems for waveform polynomial are proposed; the model and data structure for the representation and manipulation of waveform polynomial are proposed.

Meanwhile, the neural network algorithm and the multiple regression analysis method were utilized to estimate dry weight by parameters obtained from six time points such as diastolic blood pressure, ratios of bio-impendence vector norm and weight.

利用类神经数学演算法及多元回归分析，以各测量时间点之舒张压、生物阻抗向量长度比和体重为自变数做乾体重的估测。

The algorithm takes into account the relationship between noise and underlying geometric information,such as normal and curvature.

为了更好地去除噪声，并保持模型的突出特征，提出了一种鲁棒的点模型多边滤波器降噪算法，该算法充分考虑了模型表面的法向量、曲率等内蕴几何量和噪声之间的关系。

Considering the impacts of \'excessive fitting\' and \'unusual point\' on identification, a weighted least squares support vector machine which based on the normal distribution function is proposed in this thesis. Its weighted rules mainly apply some statistical characteristics of the normal distribution faction.

考虑'过度拟合'和'野值点'对辨识模型的影响，应用正态分布函数的一些特性，本文提出基于正态分布加权的最小二乘支持向量机。

By this approach, the structural features and statistical features of characters are firstly extracted, then they are normalized to the input vector of neural network, and RBF neural network is used for recognition.

该方法首先提取字符的结构特征和统计特征，以它们作为神经网络的输入向量，然后用RBF神经网络进行识别。

We have no common name for a mime of Sophron or Xenarchus and a Socratic Conversation; and we should still be without one even if the imitation in the two instances were in trimeters or elegiacs or some other kind of verse--though it is the way with people to tack on 'poet' to the name of a metre, and talk of elegiac-poets and epic-poets, thinking that they call them poets not by reason of the imitative nature of their work, but indiscriminately by reason of the metre they write in.

索夫农 、森那库斯和苏格拉底式的对话采用的模仿没有一个公共的名称；三音步诗、挽歌体或其他类型的诗的模仿也没有——人们把&诗人&这一名词和格律名称结合到一起，称之为挽歌体诗人或者史诗诗人，他们被称为诗人，似乎只是因为遵守格律写作，而非他们作品的模仿本质。

The relationship between communicative competence and grammar teaching should be that of the ends and the means.

交际能力和语法的关系应该是目标与途径的关系。
