Data - mining is kind of technique applied to practice at the very beginning . it not only applies to consulting specific database , but also deals with the statistic data , analysis , integration and reasoning the given data so as to find the connection among the compositions , guide to seek for the solution to problems and even to predict the future on the basis of the data 数据挖掘技术是一门从一开始就面向应用的技术,它不仅是面向特定数据库的简单检索查询调用,而且还要对这些数据进行统计、分析、综合和推理,以指导实际问题的求解,发现事件间的相互联系,甚至利用已有的数据对未来的活动进行预测。
The paper presents the detail design methods of supervising the remote terminal . the system could simulates field , show the data transformation dynamically , give an alarm , give data report forms and historic database . then the system transmits the data from data collected station to control center 本文对基地的机房远程监控系统提出了具体的设计方法,利用组态王设计模拟现场,动态的表示现场数据变化,实现报警、数据报表、历史数据库等功能以及将数据从各数据采集站发布到基地监控中心。
In this paper , the author propose a new gm ( 1 , 1 ) model for oscillation series using the transformation of triangle function , and change them to be the monotone series , then constructe gm ( 1 , 1 ) model for simulating prediction of original given data . 3 . research on gm ( 2 , 1 ) model , the author find that there is no law to choose the initial value of gm ( 2 , 1 ) model 因此,利用本论文提出的新的函数变换数据生成办法,提出一种函数变换型gm ( 1 , 1 )模型,即将初始的周期振荡数列首先变换成单调增加数列,再利用gm ( 1 , 1 )模型进行预报。
The degenerate elliptic problems we shall study is very closely related to rigidity problems arising from infinitesimal isometric deformation , as well as other geometry problem , such as minimal surface in hyperbolic space . in particular , the existence of solution with high order regularity is very important to investigate geometry problems . one would like to know under what conditions the solution of such equations are as smooth as the given data 通过构造辅助边值问题,建立了各种能量不等式,并利用这些先验估计,以及banach - saks定理得到了h ~ 1弱解存在性;利用退化椭圆型方程弱解与强解的一致性和已知的先验估计,还得到h ~ 1弱解的唯一性。
The magic of plotting graphs lies in being able to scale a given data value from one range to another ; that is , given a set of values like 10 , 20 , 30 , you should be able to decide exactly which points x and y coordinates on a 2 - d plane represent the data values 10 , 20 , and 30 绘图的奇妙之处在于能够将某一个给定数据值从一个范围按比例缩放到另一个范围中,也就是说,如果给定一组值,如{ 10 , 20 , 30 } ,那么您应该能够确定2 - d飞机上具体哪些点( x坐标和y坐标)表示的是10 、 20和30这些数据值。
