A general solution is to separately explore advanced algorithm on a particular location technique. However, this paper proposes a new concept called Multi-mode positioning which combines several location techniques. After a brief overview of existing technologies, the writer focuses on the function principles of multi-mode positioning system based on Client-Server architecture. The center of a triangle's incircle is used for calculating to get a more accurate positioning result on the server sides. In addition, detailed analysis of relating experimentation conducted by the writers will show the current prospects and benefits of multi-mode location system.","PeriodicalId":164945,"journal":{"name":"2012 International Conference on Systems and Informatics (ICSAI2012)","volume":"29 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-06-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115009278","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}

In this paper, the Nanhui tidal flat in the Yangtze River Estuary as study area, the two close time and HH polarized ENVISAT-ASAR images with different small incidence angles for inversion were received on May 2 and 3, 2005. Then the images based on data pretreatment were normalized for angles, and inversed bare surface roughness and moisture of the Nanhui tidal flat by using Zribi-Dechambre model. The results showed that soil roughness mostly ranged from 0.05cm~0.8cm and soil moisture mainly distributes in the range of 1%~3.8%. At last, the inversed results of soil moisture were validated by field measured data from Shanghai Geological Survey Academy. The RMSE was 3.62%.

Their interaction has usually been studied during tracking a target moving only in the horizontal direction. In these experiments catch-up saccades were invoked by changing target velocity or introducing target jumps and occlusions. Our research was focused on ocular pursuit of two-dimensional non-predictive target trajectories without target jumps. Target trajectories presented to the subjects had the same shape but moved with slow, medium and high average speeds, and each trial had the duration of 60, 30 and 15 s, respectively. During the long tracking experiments, the sequences of successive catch-up saccades were obtained and their parameters were computed. Due to the contribution of catch-up saccades, elicited during ocular pursuit, the position errors and lagging times were reduced from 30 to 50 % and larger values were obtained for higher target velocities. Analyzing the sum of tracking distances which were overcome during slow phases and during catch-up saccades, we proposed new method to evaluate subject's pursuit gain.","PeriodicalId":164945,"journal":{"name":"2012 International Conference on Systems and Informatics (ICSAI2012)","volume":"16 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-05-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115338226","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}
