AN EVALUATION PLATFORM OF MULTIMEDIA

2002年IEEE十区计算机、通信、控制和电机工程会议

作者： GU Jian YU Shengsheng ZHOU Jingli XIANG Dong ZHENG Junhao The Third research Institute of Ministry of Public Security, Shanghai china, 20003.

There is a lot of multimedia data types, related compressalgorithms and related code standards that have differentcharactenistics and adapt to different application *** the characteristics of multimedia dynamically is helpful forclearly understanding and properly using the media data. Theobjective of this research is to develop a network multimediaevaluation platform based on the client/server mode, by means ofanalyzing and comparing the feathers of main media (the series ofMPEG. ITU-H, ITU-G, JPEG, etc) compression algorithm. Theplatform, MATEP, can test and display main parameters of relatedmultimedia data. These parameters can be used in QoS control.

城市土地是一类社会—经济—自然复合生态系统,具有物理属性、生态属性、社会属性和经济属性,为城市提供生产、生活、流通、还原和调控等服务功能。然而以往的土地管理着重于土地结构、权属和用地性质的数量管理,而缺乏对土地功能、过... 详细信息

城市土地是一类社会—经济—自然复合生态系统,具有物理属性、生态属性、社会属性和经济属性,为城市提供生产、生活、流通、还原和调控等服务功能。然而以往的土地管理着重于土地结构、权属和用地性质的数量管理,而缺乏对土地功能、过程和生态资产的系统管理。土地复合生态管理从技术革新、体制改革和行为诱导入手,调节土地利用的结构、过程与功能,保证生命支持系统功能和居民身心健康得到最大限度的保护,土地的经济、生态和文化功能得以持续、健康的发展,促进资源的综合利用,环境的综合整治及人的综合发展。土地复合生态管理的评估体系将传统土地利用的一次性审批转换为连续的生态监测,及时掌握生态环境状况和变化趋势,定期对土地进行生态审计与评估,是促进土地合理使用的重要手段。土地复合生态管理要求针对土地这一复合生态系统建立一系列生态指标,并对这些指标进行适时监控,准确评估土地利用维持和变化产生的生态服务功能变化。

Acta Chimica Sinica English Edition 1989年第6期7卷 487-495页

作者： ZHANG Da-Ren WU Ji-An YAN Ji-Min research center for Eeo-Environmental Sciences Academia SinicaBeljing Institute of Semiconductors Academia SinicaBeijing Institute of Chemistry Academia SinicaBeijing

The formation and the presence of hypervalent Si in the electron donor-acceptor com- plex H_3.·SiH_3.Cl have been investigated by ab initio calculation. The results show that there is a 0.707eV decrease of energy when the complex H_***_3.Cl is formed from NH_3.and H_3.iCl, the interaction potential between the donor NH_3.and the acceptor H_3.iCl belongs to the Morse type, and the bond angle A(H-Si-Cl) versus bond length d(N-Si) presents a linear relation. The results also show that the interaction is mainly from giving the lone pair electrons in HOMO of NH_3.to LUMO of H_3.iCl, in which the 2P_z of N and the 3._0 of Si play important role. Bond N-Si is a weak n-σ*type dative one.

2011 International Conference on Intelligent Computing and Integrated Systems(ICISS 2011)

作者： Jianmin Wang 1 Changhong Yang 2 and Fuzhou Dong 1 1 School of Communications and Electrics 2 Polytechnic Institute of Jiangxi Science &Technology Normal University Jiangxi Science &Technology Normal University Nanchang china.

In order to guarantee the safety of the coal production and effectiveness better, this paper designs a monitoring system for coal mine safety based on wireless sensor networks, and gives the hardware design of sensor nodes and the flowchart of software. For the purpose of meeting requirements of monitoring signals, the system uses nRF2401 for short-range wireless communications, GPRS for long-distance wireless communications, ARM9 for center console, and MSP43.F149 is chosen as the microprocessor. center console uses Em GIS（embedded GIS） to show where disasters of coal mine break out and uses GPRS to transmit SMS to the mine command center. The system can improve the level of monitoring production safety and reduce accident in the coal mine.
