查询词典 uniform approximation

According to this understanding, this thesis tries to modify PSO algorithm in order to improve its quality of solutions. The main approches include: using uniform design to ensure the uniform distribution of initial particles in the design space; adding mutation operation to increase the diversity of particles; decreasing the maximum velocity limitation and the velocity inertia automatically to balance the local and the global search efforts; developing a new approach to treat the design variables exceeding the bounds; using extensive local searches to escape local minimum. The overall effect of these approaches can yield better results for most test problems.

有鉴於此，本文针对粒子群演化法之流程参考相关文献并稍作改变，使得粒子群演算法在结果的收敛上更具优势，本文的主要改进的方法包括：应用均匀设计的概念使得初始的粒子可以更均匀地分布在空间上；利用突变增加粒子之间的差异性与多样性；利用适当控制的最大速度限制及惯性权重控制，达到区域搜寻与全域搜寻的效果；应用新的边界处理机制处理设计变数超过上、下限的问题；利用区域强化搜寻针对粒子附近地区，再作进一步的搜索以得到更佳之结果；将各种方法综合后配合粒子群演算法使用，可以得到不错的结果。

This thesis firstly defines the uniform integrability and absolute continuity of fuzzy variables, discusses their relationships, and provides an approach to checking the uniform integrability of fuzzy variables.

We will demonstrate the specification of reference prior distribution on the random covariance matrix. We will consider the approximate uniform shrinkage prior and approximate Jeffreys' prior. Both are formulated based on the approximated likelihood function. Under generalized linear mixed models, we show that the posterior mode under Jeffrey's prior is asymptotically closer to the REML estimate than the mode under uniform shrinkage prior does.

在广义线性混合模式下，我们证明了在样本数很大时，随机效应之变异数成份的后验众数和REML估计值会近似相等，同时也建立了后验众数和REML估计值的近似关系式，并提出了比较二种后验众数与REML估计值之间远近的准则。

This is 1 the firstsharp uniform convergence result for linear transport equations in di?usive regime, aproblem that involves both transport and di?usive scales; and 2 the first uniform con-vergence valid up to the boundary even if the boundary layers exist.

这是对线性输运方程已知的第一个在扩散域中和输运扩散同时存在时具有高阶一致收敛性的算法，同时也是第一个一致收敛性在边界层也成立的算法。

The value of strain-hardening coefficient can be determined from the slope of logσ-logε curve, which is numerically equal to the maximum uniform true strain. So the strain-hardening coefficient can be used to evaluate the extend of uniform plastic deformation.

由拉伸实验得到的logσ-logε曲线的斜率即为应变硬化指数，其数值与材料拉伸变形时的最大均匀应变相等，是衡量材料塑性均匀变形能力的力学指标。

In a short, when the model is lack of fit, the uniform designs maximin the minimum power of the test and when the model is not lack of fit, the uniform designs minimum the maximin power of the test.

第三章，两组多响应模型判别的设计是多组多响应模型判别试验设计的基础，本章因此着重讨论两组多响应模型判别的试验设计。

The purposes of this experiment were to investigate the segregation of coat color in swine at vary mating types between Taoyuan and Duroc, and to understand that uniform black coat color of T was weather dominant or not to uniform red color of D, the adjusted Chi-square(χ2 ) test was used to determine the goodness of fit for Mendel's law of segregation.

本试验的目的是调查桃园种与杜洛克猪只各种配种型态产生后代之肤色分离情形，并以矫正之卡方测定进行遗传分离适合度检定，以了解桃园种全黑色肤色的基因与杜洛克全红色肤色基因有无显隐性关系。

They are presented in need of special curves and surfaces in engineering applications. In order to prove that the uniform C-B-spline basis is normalized totally positive, we compute the matrix which transforms the C-Bézier basis into the uniform C-B-spline and decompose this matrix into a product of. bidiagonal and stochastic factors.
