查询词典 upper bound

In the case that there is no a priori knowledge of the upper bound and lower bound of the unknown parameters, the switching adaptive control design approach is presented.

在非线性系统中未知参数的边界值未知的情况下，提出了切换自适应控制设计方法。

By exploiting the important properties of robot dynamics, the second strategy removes the requirement of a priori bound on parametrer uncertainty and weakens the restriction on external disturbance. The only requirement is to know an upper bound of the norm of inertia matrix, which is not necessary to be the smallest.

第二种算法利用机器人固有的结构特性，减弱了目前已有文献对未建模扰动的限制，它不要求预先知道机器人结构参数的不确定范围，仅要求已知实际惯量矩阵范数的一个上界。

Two methods are presented to calculate the lower bound and upper bound on the bisection width of H-Torus topology.

针对H-Torus拓扑结构，给出两种确定该拓扑结构等分带宽上、下界的方法。

In this paper, we expand the eigenvalue of Poisson equation using nonconforrn-ing Q1rot element. The principal term of error we get is not negative. In general, the approximate eigenvalue is the upper bound, but the approximate eigenvalue may be the lower bound when the principal term is zero.

本论文对Poisson方程的特征值采用方形旋转双线性非协调元Q_1~(rot元进行展开，得出的误差主项大于或等于零，因此在一般情况下近似特征值是上界，但当主项等于零时近似特征值可能是下界。

As the upper bound of the 90 percent confidence interval for RMSEA was 0.37 and the lower bound was 0.03, the degree of approximation for the comprehensive model in the population was acceptable.

对于初中学生学习有望模式与高小学生学习有望模式，χ〓差别测验显示两个模式的差别是显著的(Δχ〓=34.436；Δdf=13；p＜0.05)，这个结果表示初中学生与高小学生有著不同的学习有望模式。

The upper-bound counts and the lower-bound counts of Bent functions are proposed by researching the Hadamard matrix, which decrease the searching space of Bent functions.

通过正规Hadamard矩阵研究给出了GF(2~n)上Bent函数计数的上下界，降低了Bent函数搜索的空间。

The tree structure of large organizations sets an upper bound on freedom, not a lower bound.

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.

利用拟凸-凹扩张中构造出的函数的拟凸下界函数和拟凹上界函数，与分枝定界方法相结合，建立了求一般约束全局优化问题的拟凸松弛算法，这一算法是将盒子约束的区间算法推广到一般约束优化问题中。

The upper bound of error probability is used as the criteria of clustering and the evaluation of the clustering result. On the basis of initiatory clustering based on distance functions, the algorithms named"pick-over"and"fill-up"are proposed to minimize the upper bound of error probability.
