The stereo image pair is acquired by a pair of calibrated cameras. Global disparity of foot is estimated at first. After the image pair is preprocessed automatically, using non-contact information-collecting technique and phase-correlation method, which is based on complex wavelet, surface matching with sub-pixel accuracy in the frequency domain is carried out. By taking order matching constraint, continuity constraint and correlation constraint together, 3D point cloud of foot is reconstructed and 3D model of foot is built by mosaicking point cloud at various angles automatically. After normalization, high-order moments are compared, which is useful for the subsequent shoe last design.

Quasi-convex relaxation algorithm, which aims to solve ordinary constraint global optimization problems, is produced by a combination of branch-and-bound method with quasi-convex lower bound and quasi-concave upper bound functions developed from quasi convex-concave extension. This algorithm extends the interval algorithm with box constraint to general constraint global optimization problem.

OWL Lite 包括基数约束﹐它也称作局部约束﹐因为它们是宣告在某些特定类别的属性上面﹐也就是说这个约束限制了该类别实体的属性基数。

As a result, this seriously obstructs economic development step of our country. Therefore, starting from system and no-system, the paper sets up incentive and constraint mechanism according to the combination of material incentive and spirit incentive, long-term benefits and short-term benefits, system together with organize constraint and constraint by himself/herself, in order to solve the problem of agency and individual objective of manager deviating enterprise objective.

The rotor and its bearing, linked with small clearance restrict, makes up of the whole rotating system of unit power in ball pen production machine; its breakage and failure, first appear in the form of the failure of small clearance restrict, is caused directly by the unit vibration. Therefore, how to ensure good dynamic characteristics of rotating system is the thing worthy of note.

在多工位制笔机械的小动力头旋转系统中，转子与其支承之间是依赖小间隙约束而构成完整系统的，机组失效也总是最先表现在这类小间隙约束的破坏与失效上，而机组振动则是导致小间隙约束破坏的直接原因。

This algorithm is bases on that the number of period constraints of a circuit is great larger than that of non-negativity constraints on pracitical circuits. At first, we classify the pathes, and then compute the bounding of the retiming value.

接着根据实际电路中周期约束远远大于权重约束的情况，提出一种减少周期约束的算法，算法首先将路径分类，由不同路径来确定重定时值的取值区间。

Based on these plans, new plans were designed through replacing the physical constraints with maximum EUD for parotids, while keeping the physical objectives for targets and other organs at risk unchanged.
