The 3D model of 5-DOF branched-chain is established and the parallel mechanism is assembled strictly by UG. Finding all translational parts one by one, the adjacent parts during motion are packaged into a whole transform statement in order to streamline procedures. The mechanism's translational motion simulation is realized while the corresponding parts make the rotation and translation movements. Result shows that mechanism's motion simulation under Internet can be observed and the solution validity is verified.","PeriodicalId":412601,"journal":{"name":"2010 International Conference on Multimedia Technology","volume":"28 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-11-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124340192","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The updating investigations mostly depend on the conventional means which has constrained the mine production on in-depth understanding of the geological terrain. So it is urgent to carry out the research work. The use of remote sensing techniques and auxiliary data to carry out the research work provide the basic data and technological support for the updating methods of mining area terrain by quickly, accurately getting knowledge of mining geology and environment information. This study updates the surface topography of a mine in Henan by use of the high-resolution data .The main contents are as follows: 1) pre-processing the data(geometric correction, radiometric correction); 2) using Laplace filtering arithmetic combined with corrosion operation and edge detection technology to semi-automatic or automatic extract the houses, roads on the fusion of high-resolution QUICKBIRD data.","PeriodicalId":412601,"journal":{"name":"2010 International Conference on Multimedia Technology","volume":"51 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-11-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124496637","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The results show that the total amount of soil erosion is 2850069.39 t/a in 2007. Moderate erosion area is predominant, occupying 34.16% of the region. Spatial distribution pattern of soil erosion is an obvious block distribution characteristic. Soil erosion is the strongest from 200m to 500m in different elevation zones in the study area. Soil erosion at a 15° to 30° incline is the strongest and the weakest is over 35°. Soil erosion in the northeast is the strongest, but soil erosion in the southeast is intermediate. The strongest erosion is in forestland soil of different land use types, and the second strongest is in grassland soil.

A new method is presented in this paper, which utilizes SAR image and point target analysis method to identify islands on sea surface in near and far range from mainland, especially for islets which can be confused with big ship or other objects such as floating, oil platform and so on. In the sea, either islands or islets is static objects, and other thing is dynamic characteristics, according to this characteristics, islands can be distinguished by spaceborne synthetic aperture radar (SAR) images joint point target analysis (PTA) method.

In the IOT system, there may be more than one tag in the working range of one reader. When the reader start these tags, all of them will transmit data to the reader at the same time, it will cause the reader can not read the data from the tags correctly. Use the anti-collision technology the IOT can prevent multiple tags simultaneously transmit data which causes collision. The current anti-collision algorithms are mainly Slotted ALOHA method and Binary Search method. The basic ALOHA algorithm has high current efficiency, but with the increase of the tags, the efficiency of the system will decrease greatly. This paper presented an improved ALOHA algorithm. In the proposed algorithm, the number of tags was estimated dynamically, with which a suitable size of window can be chosen to get higher system efficiency. At the same time, grouping strategy was introduced into the algorithm. The simulation results have shown that the proposed algorithm has higher system efficiency and lower working time.","PeriodicalId":412601,"journal":{"name":"2010 International Conference on Multimedia Technology","volume":"33 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-11-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126404160","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Namely, in continual space and a large time scale, an adequate discussion was made for the temporal and spatial vicissitudes of industrial cluster and the spatial correlation of population and GDP of Liaoning Province, and regional differences of per capita income and employment population of the State of Ohio. And at last, with whole population, employment rate, per capita income and per capita GDP as indexes, this paper made a comparison between the Spatial and Temporal Patterns of Economic Development of Liaoning Province and the State of Ohio. The conclusion are that per capita income in the State of Ohio shows a corresponding increase trend with the total population and employment population, while in Liaoning Province, the polarization of GDP is very distinct. Even for counties beside Shenyang and Dalian, the two central cities which hold a safe lead, the GDP and employment rate are not high. This phenomenon shows that comparing with the State of Ohio, in Liaoning Province, the spatial correlation is not so distinct, the aggregation is not so strong, and there is a big gap in the overall economic conditions. These patterns remind us that in the future we should pay enough attention to spatial distribution and its promoting effect on the economy.","PeriodicalId":412601,"journal":{"name":"2010 International Conference on Multimedia Technology","volume":"183 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-11-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121944526","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
