数据相关性 meaning in English
data dependence
data dependency
Examples
- The bottleneck of performance include : the ability of handling data ; the ability of transfering data , if the necessary data is not in local memory , the processor cant work ; the dependency of data , parallel handling the data which be known beforehand
以往的dsp和媒体处理器缺乏mpeg2编码解码的实时处理能力，性能瓶颈主要包括：数据处理能力；数据传输能力，当所需数据不在本地内存时，处理器无法进行任何操作；数据相关性，预知数据并行处理。 - The main content of this paper is compress arithmetic of multi - spectral image , and the implement with fpga . in the phase of preprocess , the paper analyses the characteristics of multi - spectral image , classifies data redundancy to two classes : spatial - redundancy and spectral - redundancy , afterwards , eliminates these data redundancy with different forecast models
在预处理阶段,本论文分析了多光谱图像的数据特点,将多光谱图像数据中存在的数据冗余分为两大类:空间冗余和谱间冗余,再针对每种冗余使用相应的预测模型消除数据相关性。 - Now , there are four evaluation methods in this field , every method has its advantages and shortages and most of them are established based on highway . high weight communication , great loads channelized traffic and high speed is the expressway ' s feature , there is great difference in the development law between highway and expressway . we will get some unfitness result by using those evaluation methods to evaluate expressway
目前国内外常用的四类路面使用性能评价方法中回归法评价结果与实测数据相关性不太理想，系统分析法客观性不强，灰色理论法存在一定的主观经验性，其它一些方法还处于研究阶段；而且这些方法都是基于普通公路建立，高速公路具有交通量大、汽车轴载重、交通渠化和行车速度高等特点，路面使用性能的特点和发展变化规律与普通公路存在较大差异。 - The dynamic distributed principia on the simulation module are given , as well as the dynamic analyses arithmetic on the load of the servers . the arithmetic which to test the data pertinence of the simulation module which driven by the data source is put forward . the dissertation also designs an efficient distributed arithmetic on the simulation module the concept of xml template is put forward to realize the save format and the backward - compatibility of visualize edit interface system

摘要通过抽象出无线传感器网络中区域数据回传的网络模型，定量研究了区域数据聚合的节能条件，证明了先聚合再回传比直接进行数据回传所节省的相对路径长度,如果大于等于数据相关性与源节点个数的比值时，区域数据聚合一定可以节省能耗，并进一步给出了当数据聚合点在网络的不同位置，或数据的空间相关性不同时，区域数据聚合的节能条件。
