In order to improve the robust and precise in image registration,we get the Hessian matrix removed to improve LMA for searching the eight unknown parameters of two input perspective transformation images and get computational gains.

为提高图像匹配的精度和稳定性，在图像匹配过程中用消除了Hessian矩阵的LMA改进算法对两幅图像透视变换矩阵的8个未知参数进行拟合，减少了迭代的计算量。

Proofs that when iterating with the BP algorithm, if one of the neural units fall into saturation regions at least, and the other one at least don't, then the condition number of the Hessian matrix of the error function is very larger.

证明了BP算法在迭代过程中，如果至少有一个神经元落入饱和区而同时至少有一个没落入饱和区，则目标函数的Hessian阵的条件数变大，这是导致"网络瘫痪"现象的原因，也是BP算法收敛速度慢的主要原因。

Recently, it is a hot research at home and abroad in portioning groups of the matrix to iteration which is based on the structure of the Hessian.

近年来，结合稀疏Hesse阵的结构，按照分划组的思想将矩阵列分划进行迭代是国内外研究的一个热点。

Then, we investigate iterative methods in Hilbert spaces for solving such problems in the second part.

本文在第二部分讨论了Hilbert空间中均衡问题的近似迭代解。

He also overlaps Hinton in time, dealing in the main with the Liberation War (civil war after the Japanese surrender), but with many references to the past and to the course of the civil war in other regions.

时间上同韩丁也有所重迭，写的主要是解放战争（日本投降以后爆发的内战），但也追溯许多历史背景，并提及其他地区内战进行的情况。

In the third chapter,we study mainly iterative roots of piecewise homeomorphic maps of an Y-star.

在第三章，我们主要研究了Y星上逐片同胚映射的迭代根的问题。

In this paper, we discussed mainly the iterative roots of piecewise homeomorphic maps of an Y- star.

A b distribution function is proposed to replace the homogeneous distribution function in the particle optimal algorithm. It use a dynamic method to adjust the parameters of b distribution random function to improve the speed and quality of the feasible solution.

提出使用b分布函数来代替均匀分布函数的粒子群优化算法，在产生可行解的过程和迭代过程中动态地调整β随机函数的参数，以提高产生可行解的速度和质量。

In the homogeneous model, the function of tendons is assumed to be uniform in some approximated way in order to form an equivalent homogeneous material within concrete. The formulation of the homogeneous model is same with that of general FEM for common continuum, let alone the elastic matrix being resultant of that of tendon and concrete. The computation is simple, but the approximate assumption makes this method cannot be generalized, because it only represents the constitution and function of tendons in such a rough way, that the numerical results are inaccurate. In the combined model, the function of tendon is considered by the stiffness matrix with rod element, then add it into the stiffness matrix of concrete by a rational way.

均匀类单元是设想将钢筋均匀弥散于整个单元中，使其成为一种连续均匀材料单元，这种单元的与一般有限元的单元刚度矩阵推导过程一样，只不过其弹性矩阵由混凝土和钢筋两部迭加而成的，此类单元刚阵计算简明而又不会扩大计算规模，但均匀弥散只是为计算简单而作一种假想，不贴近单元构造实际，也不符合实际作用效果。

And Pharaoh spoke to Joseph, saying, Your father and your brothers have come to you.
