In this paper, we propose a new approach to recognize occluded objects. The information of the magnitude of the local extreme of the open angles in the contour of a model at a scale, the information of the distance and relative location between the two adjacent dominant points are suitably integrated as a set of features for describing a model, the features are invariant under rotation, uniform scaling, and translation of the curve.

该文提出了一种新的识别有遮挡目标的方法，即将目标模型和含有目标的遮挡图象的轮廓在某一尺度上张角的极值、极值点之间距离、相对位置等信息集成在一起，作为描述目标模型的一组特征，且这组特征在平移、旋转和均匀尺度变换下保持不变。

the fast transposition algorithm to sparse matrix expressed by triple list is introduced.this algorithm needs to determine the position in the transposed matrix position of the first element which is not equal to zero in the original matrix each row,it uses two arrays as auxiliary space.in order to reduce the auxiliary space which the algorithm needed,an improvement is made through introducing two simple variables.the improved algorithm saves a half auxiliary space compared to the original algorithm at the same time complexity.

摘 要：介绍基于三元组表表示的稀疏矩阵的快速转置算法，此算法在转置前需要先确定原矩阵中各列第一个非零元在转置矩阵中的位置，在此使用2个数组作为辅助空间，为了减少算法所需的辅助空间，通过引入2个简单变量提出一种改进算法。该改进算法在时间复杂度保持不变的情况下，空间复杂度比原算法节省一半。

But Rafa's positioning of those players is obviously working; its December, and he is undefeated.

拉法对他们位置的安排目前看来是成功的，球队到十二月仍然保持不败。

Able to change his grip to adjust with bounces – even when forced able to slice the old-school squash shot with underspin – Federer's mechanics are at once austere and elegant. His head is always balanced, his eyes tracking the ball keenly, his feet rarely out of position.

能够通过改变握拍来适应不同来球——即便是处于被动，也可以击出下旋球来打开局面，他的击球既严谨又优雅，他的头始终保持平衡，眼睛盯准来球，步伐总是在最合适的击球位置。

Whereas, hitches for a two wheel trailer have to use a special universal joint to keep the trailer always in the upright position.
