Examples
- The thesis ends with researches of the object - oriented design patterns of gridless software , which bases on the cloud structure . in order to reuse the software design and make it more flexible , the base function classes have been divided , and a series of common design patterns have been put forward in the frame design of gridless software
本文还对基于点云结构的无网格计算软件的面向对象设计模式进行了研究，着重于提高软件的复用性和灵活性，划分了此类软件中的基本功能类，提出了一系列常用设计模式，对无网格计算软件整体框架设计进行了有意义的探索工作。 - The primary contents are as follows : ( 1 ) in allusion to the practical conditions of working process of the sugar cane combine harvester , according to the function class and the mechanical capability of machine , construct the whole structure of design and evaluation expert system of sugar cane combine harvester based on deeper researching in harvester design field knowledge
其主要内容如下： ( 1 )针对甘蔗收获机械工作过程的实际情况，根据机构的功能分类和机构的机械性能，在较为深入地研究甘蔗收获机械设计领域知识的基础上，构建了甘蔗收获机械设计与评价专家系统总体结构。 - It comes up with a new notion , d - solution , which is applied to the distance estimation , by virtue of hilbert space ; furthermore , the dissertation has gained a necessary condition which is identity of minimum mean - square value in linear function classes , so that d - solution extends minimum mean - square value within the domain of nonlinear function equation or equation system ; and , the dissertation studies in detail the classical moment estimation and maximal likelihood estimation on the parameters of ar ( p ) , a series of theorems in the estimation section shows the moment estimators are consistent on the ground of large samples jikewise , those distribution functions of the estimated parameters accord to maximum likelihood estimation converge gauss distribution if the white noise is gaussan
首先，借助hilbert空间理论，提出了距离估计的d -解，给出了d -解的必要条件，这个条件在线性函数类里即是极小二乘估计法， d -解的必要条件满足的方程实质上将极小二乘估计法推广到多函数及非线性函数类。再而，详细地研究了多元弱平稳序列自回归模型ar ( p )的参数经典的矩的替代估计和极大似然估计，获得矩的替代估计的一致性的结果。对基于gauss白噪声假设多元弱平稳序列自回归模型的均值、白噪声的协方差阵的极大似然估计都有依分布收敛到多元正态分布的统计性质。
