It is used to solve the uncertainty of the optical ultra-precision instrument vibration isolation platform. And the wavelet theory is used to analyze the random vibration signal in the time-frequency domain and get the low frequency signal from the random vibration signal. Then the μ controller designed by the μ control theory is used to restrain the low frequency vibration. The experiment results prove that this method has shown good robustness and control precision in the vibration isolation of the optical ultra-precision instrument.","PeriodicalId":6408,"journal":{"name":"2009 International Conference on Environmental Science and Information Application Technology","volume":"31 1","pages":"807-810"},"PeriodicalIF":0.0,"publicationDate":"2011-03-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"76657647","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}

Nowadays in dataglove-driven motion capture field, researchers preprocess the raw sensor data of the glove with calibration methods for acquiring a high precision in the VR environment. But there are still alternative solutions. Some machine learning algorithms, for example the self-organizing map method, offer a powerful capacity in the case of hand gesture recognition with uncalibrated glove data. We present the reason we introduced the SOM into the recognition process and how it works. Our goal is to construct a stable and robust mechanism to recognize hand gesture and then put it into hand gesture control system as an interaction platform for virtual reality.","PeriodicalId":6408,"journal":{"name":"2009 International Conference on Environmental Science and Information Application Technology","volume":"38 1","pages":"1362-1366"},"PeriodicalIF":0.0,"publicationDate":"2011-03-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"84154296","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, we present an Kalman filter algorithm based on error state variables in SINS + GPS navigation application. The mathematical model of the errors of GPS data and inertial navigation data is linear, so the errors are taken as the states, which avoids the complexity caused by nonlinear and makes the design difficulty reduced significantly. This paper also gives the design process and the mathematical model of navigation system, and sets the state parameters of the model. Finally, simulation results show the effectiveness of the algorithm.","PeriodicalId":6408,"journal":{"name":"2009 International Conference on Environmental Science and Information Application Technology","volume":"9 1","pages":"770-773"},"PeriodicalIF":0.0,"publicationDate":"2011-03-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"84215254","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, in recent 48 years, the average annual pan evaporation of Linyi city is significantly decreased by 35mm/10a, by 95% confidence inspection. Annual pan evaporation is mainly reduced in spring, summer and autumn, and especially in summer the confidence level reached 99 percent. In 1983, annual pan evaporation reduced suddenly. The main reason of the decrease of pan evaporation is the significant reduction of sunshine duration and daily temperature range and the significant increase of low cloud cover and vapor pressure.","PeriodicalId":6408,"journal":{"name":"2009 International Conference on Environmental Science and Information Application Technology","volume":"13 1","pages":"636-642"},"PeriodicalIF":0.0,"publicationDate":"2011-03-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"84498719","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 order to apply large-scale modeling data to paleoclimate research in local regions, an effective downscaling model based on three-layer back propagation neural network (BPNN) is developed. Observational and ECHO-G simulated data are employed to train and test the BPNN model. With proper training and validation, BPNN model exhibits its ability to paleoclimate estimation, it is applied to reconstruct monthly (January and July) and annual mean temperature and precipitation in Anhui-Hubei region during the last millennium. The results indicate that BPNN model extracts useful climatic information from observation and simulation and provides fairly accurate paleoclimate estimation. This downscaling method is a successful trial of applying BPNN in local area of paleoclimate modeling, in the meantime, it improves the capacity of researching on paleoclimate variability in local regions using large-scale modeling data.","PeriodicalId":6408,"journal":{"name":"2009 International Conference on Environmental Science and Information Application Technology","volume":"63 1","pages":"1292-1295"},"PeriodicalIF":0.0,"publicationDate":"2011-03-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"82074998","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}
