数据信息

The water body was extracted by combining density slicing of TM 5 or TM 7 with the terrain mask produced by DEM. NDVI was used to extract vegetation information, and desertification land and salification land information was extracted by the SAM classification method. Confusion matrix shows that the classification precision is 86.2%.

The researchers can get the relative information quickly by collecting, organizing and managing the data and then use the information expediently. We can gain the deep-seated biological knowledge by dealing with and digging the data and then enhance our understanding to the biology world. In the applications and researches of biology and iatrology we can improve the efficiency and scientize the researches and exploitation by using the data and analysed results. Just like to examine the related genes of some disease basing on the result of analysing the genes' fuctions and to design a new medicine basing on the results of analysing the protein.

The predictor (22) determines the location of the most pertinent activity by examining at least one of: video data, audio data, and other data such as closed captioning information.

预测器(22)通过检测视频数据、音频数据以及诸如封闭标题信息的其它数据中的至少一个来确定最佳动作的位置。

But extensive application of information technology also brought new problems. For example: information overload; complicated system; confuting data. It is very difficult to organize information according individual needs. Kinds of system can not help each other and improve efficiency.

但各种信息技术的广泛应用也给企业带来了新的问题，如信息过载、系统过于复杂、数据互相冲突，难以根据个人需求对信息进行组织；各种系统之间难以建立协助，无法发挥最佳的效率等。

The playfulness of "Digital Cubes" does not try to disguise its symbolic parallel to meaningful social interaction; while "Wave Bubble" examines the boundaries of privacy in a conglomerated, technologically intrusive environment,"Freedom Flies" proposes alternative models for social awareness and provides new ways for information freedom and democratization. In the same vain is a suit of software tools called "Open Government Information Awareness" designed to monitor government performances allowing everybody to access official data sets and build profiles of those in the government, reversing the course of big-brother's control on the individuals. Also included in MIT's exhibit is "ScreamBody", a wearable space for screaming. ScreamBody silences the screams so the person may feel free to vocalize without fear of environmental retaliation, and at the same time records these for later release where, when, and how the person chooses.

趣味十足的&数字立方&并不掩饰其社会互动的象征意义；而&飘动的泡沫&则检视了在科技日益无所不在的环境里个人隐私的存在界限；作品&自由飞翔&无疑为民众的信息自由意识和民主化提供了新的选择模式；同样，为监督政府行为而设计的以便于民众获取官方数据的成套软件工具&开放政府信息的觉醒意识&则是个人对政府信息强权控制的反叛；当然还有麻省理工学院的&呐喊的身体&，一个可佩带的用于呐喊的装置，&呐喊的身体&能够对喊叫进行消音处理，能够让喊叫者不必担心周围环境受到呐喊声音的打扰而自由地放声喊叫；并且能够同时记录这些声音，用户可以根据自己的需要任何时间、任何地点都可以再次释放这些喊叫声。

Synthetically considering these characteristics, the method of freeway management and control are presented according to four aspects: system objective orientation and concept design, system demand and requirement analysis, system data management and network structure, traffic control and accident detecting theory as well as its application. Function and structure of system are delimitated from the point view of integration. Construction and function demand of subsystem are analyzed and basic implement projects are presented. In this thesis, system data flow and management method and target which based on system network topology structure and equipment demand are described.
