Prediction of the effective wind power density is a significant work for wind power evaluation. In this paper, the effective wind power density values are regarded as a time series, furthermore, Back Propagation Neural Networks (BPNN) and Generalized Regression Neural Networks (GRNN) are employed to forecast the effective wind power density in the future. Both the two models predict the effective wind power density only based on historical data and statistical calculation, combining the long term prediction and the short term prediction. Forecasting and calculation results show that the neural networks have strong learning ability that can well capture the random changes of time series researched. Compared the forecasting results of the two neural networks mentioned above, the Back Propagation Neural Networks performs better than the Generalized Regression Neural Networks for effective wind power density prediction in Hexi Corridor.","PeriodicalId":412601,"journal":{"name":"2010 International Conference on Multimedia Technology","volume":"12 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":"126570884","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}

Free multi-temporal Landsat imagery data provided a feasible approach to monitor shifting mangrove wetlands in China. In order to know the historic and present situation of the west shore of Donghai Island mangrove, a new integrated classification method with Support Vector Machines (SVM) and Decision Tree (DT) was applied, which is more effective than SVM algorithm. The integrated method combined the information of spectrum, spectral transformation and geographical position for land cover extraction. Post-classification change detection was used for analyzing the mangrove loss conditions and its possible reasons in the past three decades. The results informed that the mangroves in the study area has been most affected since the early 1970s, nearly 62% of the mangrove area has lost.

Considering both the reliability and the efficiency performance of sensing, we use the average error probability (AEP) in final decision making as metric. We derive a closed-form expression of AEP by classifying cognitive transmission into six cases. In order to minimize the AEP, we consider the optimization of cooperative sensing with energy detection, and find the optimal fusion rule among all of these counting rules. Finally, we verify the theoretical analysis by numerical results.","PeriodicalId":412601,"journal":{"name":"2010 International Conference on Multimedia Technology","volume":"94 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":"132665178","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 simulation also demonstrated that the cumulative evapotranspiration in the 150 ㎝ soil profile at upper slope is higher than lower slope. In conclusion, it's advantageous for tillage soil at the lower slope to keep soil moisture and resist the drought in the peanut field during dry season in southern China.
