And the on chip data memory is byte addressable double data buffer structure, so that the unaligned data load and store can be supported and data can be prepared by DMA engine concurrently with computing.Finally, a video application specific SoC platform design and optimize. In video SoC platform, the embedded RISC processor and EDO-SIMD video processing engine were integrated with the DMA and LCDC etc. IP based on AMBA SoC interconnection and dedicated communication channel.

在片上数据存储的设计中，采用了Byte可寻址的双data-buffer的策略，既可以支持内存的非对齐访问，又可通过DMA并发完成数据的搬运。3视频处理SoC平台的设计基于AMBA总线和主要处理引擎间专用信道的SoC互连，以嵌入式RISC处理器和基于EDO-SIMD指令体系的视频处理擎为核心，配以DMA和内存控制器等外设，构成了一个基本的异构多核视频处理SoC平台原型。

Work in this paper focuses on the data mining from chromatographic retention index data. A retention index database that contains about 50000 records of retention index is firstly established. Projection pursuit technique is then utilized to do data mining upon the data in order to find out some valuable information about the relationship between the retention indices and structural descriptors. A novel algorithm for projection pursuit is developed in this work. Samples of alkane, alkene and cycloalkane are investigated.

Surface ozone data of Mauna Loa and the other 14 monitoring sites of altitude lower than 1000 m in the northern hemisphere were used to give a joint discussion for the distribution and variation features of surface O3. The data, based on ground observation, were collected, processed, and distributed by WDCGG (World Data Centre for Greenhouse Gases) in GAW. The monthly mean and hourly data of surface ozone in these 15 sites were analyzed to sum up the difference of surface ozone annual and seasonal variations in different areas of the northern hemisphere.

利用来自GAW（Global Atmosphere Watch，全球大气监测）的、由WDCGG World Data Centre for Greenhouse Gases，世界温室气体数据中心）收集整理和发布的、基于地基观测的北半球共15个站点的地面O3含量的逐月观测资料以及逐时观测资料，分析、对比并总结了北半球不同经纬度各区域的地面O3含量的年变化和各个季节的日变化规律。

The main program directory within the subdirectory called data storage systems, database files change, in order to facilitate the procedure call, in the BDE Dalphi management window to establish "SPXSGL" database alias. As shown in figure 2, directory location for "... sales management system data."

在主程序目录内建立名为data的子目录存放改系统数据库文件，为了方便程序调用，要在Dalphi的BDE管理窗口中建立"SPXSGL"的数据库别名，如图2所示，目录位置为"…商品销售管理系统data"。

Since scientists and researchers think of data as a singular mass entity like information, it is entirely natural that they should have come to talk about it as such and that others should defer to their practice. Sixty percent of the Usage Panel accepts the use of data with a singular verb and pronoun in the sentence Once the data is in, we can begin to analyze it. A still larger number, 77 percent, accepts the sentence

既然科学家和研究工作者认为资料和信息一样是一个单一的团体，他们就应该这样地来谈论它并且其他的人应当服丛他们的说法，这是完全自然的，百分之六十的用法专题使用小组成员接受把data 和单数动词和代词连用，如在句子一旦资料来了，我们就能开始分析了中，更大的比例，即百分之七十七的成员接受了句子

And the efficiency and precision of three methods have been analyzed and contrasted by using the CRISP_DM (Cross-industry Process for Data Mining) frame and the step of business understanding, data understanding, data preparation, modeling evaluation and development.

以CRISP_DM(Cross-industry Process for Data Mining)方法论为建模过程框架，按照商业理解、数据准备、建立模型、模型评估、模型发布的步骤，在建模过程中对三种算法的效率和精度进行分析和对比。

A device that converts data from one form into another, as from one form usable in data processing to another form usable in telephonic transmission.Also called data set

调制解调器，猫：将信号由一种形式转换成另一种形式的装置，如在电话传输中由一种数据处理可用形式转换成另一种可用形式也作 data set

Along with the rapid development of Web data and data integration technology,semi-structured data have aroused people's more recognition.The semi-structured data is a kind of self-described data whose structure is unprecise or connotative.

1引言半结构化数据是介于毫无结构的天然数据raw data和传统数据库中严格结构化的数据(如关系数据库中的表或对象数据库中的有序图)之间的一种自描述性数据[1，2]。

Although any unimodality type partially expresses limited semantics less or more, video semantics are fully manifested only by interaction and integration of any unimodal. Video data comprises plentiful semantics, such as people, scene, object ,event and story, etc. A great deal of research has been focused on utilizing multi-modality features for better understanding of video semantics. Proposed in this paper is a new approach to detect semantic concepts in video using co-occurrence data embedding, SimFusion, and locality preserving projections from temporal associated co-occurring multimodal media data in video.

该方法对所提取视频镜头的多模态底层特征，根据共生数据嵌入(co-occurrence data embedding)和相似度融合进行多模态子空间相关性传递而得到镜头之间的相似度关系，接着通过局部不变投影(locality preserving projections)对原始数据进行降维以获得低维语义空间内的坐标，再利用标注信息训练分类模型，从而可对训练集外的测试数据进行语义概念检测，实现视频语义信息挖掘。

Data and bss define the section to be a data section, analogously to code. Data sections are marked as readable and writable, but not executable. data declares an initialised data section, whereas bss declares an uninitialised data section.

data和bss定义一个数据段，类似code，数据段被标识为可读可写，但不可执行，data定义一个被初始化过的数据段，bss定义一个未初始化的数据段。

The split between the two groups can hardly be papered over.

这两个团体间的分歧难以掩饰。

This approach not only encourages a greater number of responses, but minimizes the likelihood of stale groupthink.

这种做法不仅鼓励了更多的反应，而且减少跟风的可能性。
