摘 要:分析了建立矿床地质模型传统的估值方法的不足,针对地质变量之间具有空间局域性、连续性和各向异性,以及高度非线性关系的特征,阐述了应用人工神经网络原理和方法建立矿床地质模型的可能性和优越性,建立了地质变量参数估值计算的神经网络模型的基本结构,描述了地质变量与其影响因素之间的非线性映射关系,从而提出了基于人工神经网络原理的地质模型估值方法。

In the traditional AdaBoost method,the weights are updated based on the weak classifier's overall error rate, this article proposes one kind of the method which unifies the level of difference between the threshold and the feature value of the weak classifier with the weak classifier's overall error rate. Compared to the method which only based on the overall classification error rate to update the weights,this method can achieve higher detection rate while reduces the mistaken-detection rate.

在传统AdaBoost方法中,权重是根据弱分类器的整体错误率来更新的,本文提出了一种将弱分类器的阈值与特征值相差程度和弱分类器的整体错误率相结合来更新样本权重的方法,相比较只根据整体分类错误率来进行权重更新的方法,这种方法可以在降低误检率的同时达到较高的检测率。

According to the needs of individual three-dimension human-form modeling, the improved measurement method is suggested, in which the traditional contact measurement method of mannequin and the measurement of human additional characteristic, such as the thickness and width, interval of breast, breasts' highth, buttocks high and so on, are combined.

研究了三维人体数据的获取方法,主要分析了接触性测量和非接触性测量方法的特点,根据个性化人台建模需要,提出基于服装行业传统的接触性测量方法的改进的数据测量方法,提出增加测量人体附加特征尺寸,例如胸径厚度、乳间距、乳高、臀高等特征尺寸。

By analysising cost and output for low yield oil wells, in the paper, the method of flow switch is used to judge if the well bore has the oil flows, which change the traditional experienced method (touch the beam hangers temperature and look if it has the oil film) and the present automatic liquid level monitoring manner, and it is the closed-loop control and reduce the intensity of labour and the cost of the production. The hill-climbing mathematical method is considered as the most effective way.

论文中采用了流量开关的方法判断井口是否出油,打破了传统用经验判断(看抽油杆是否发热、是否附有油膜)的方法和现有的自动液位监测仪判断方法,形成了闭环控制,降低了劳动强度和减少了生产成本;并将数学方法上的瞎子爬山法用在了本优化控制系统中。

Three new fringe subdivision methods are first proposed opposing to the restrictions of the traditional subdivision methods. They are fringe subdivision method based on self correlation coefficient, fringe subdivision method based on gene algorithm and fringe subdivision method based on Fourier-transform.

本文针对传统软件细分方法的局限性,首次提出了三种新的条纹细分方法:基于自相关系数的条纹细分法、基于遗传算法的条纹细分方法和基于傅立叶变换的条纹细分方法。

Compliant mechanisms are defined as mechanisms that gain some or all of their motion due to the relative flexibility of part or all of their members. Therefore, the design method of compliant mechanism is greatly different from that of traditional rigid-body mechanism and the design methodology for compliant mechanism has not been established systemically till now.

柔顺机构是一种依靠自身的部分或全部具有柔性的构件变形来输出运动或力的机构,它的设计理念及方法与传统的刚性机械设计方法有很大的不同,至今未形成系统完整的设计方法,本文针对这一问题,在国家自然科学基金和国家863计划项目的支持下,提出了轨迹输出平面柔顺机构的一整套设计方法。
