Soil moisture is a key parameter in the land-atmosphere interactions over the Tibetan Plateau (TP), which plays an essential role in the Asian monsoon processes. Validation of satellite observed and/or modeled surface soil moisture is a particularly challenging work due to the scale issues. Additional challenge in this area is the harsh environment and heavy workload to establish a Soil Moisture and...
Existing noise metrics and modeling for noise induced hearing loss (NIHL) have limitations on prediction of gradually developing NIHL (GDHL) caused by high-level occupational noise. In this study, two auditory fatigue models have been proposed for prediction of GDHL in human. The generalized mammalian auditory model incorporating dual resonant nonlinear (DRNL) filter is used to obtain the velocity...
In order to acquire more accurate crop yield information, the global optimization algorithm SCE-UA was used to integrate leaf area index derived from remote sensing with crop growth model EPIC to simulate regional summer maize yield and field management information in Huanghuaihai Plain in China. The results showed that the mean relative error of estimated summer maize yield was 4.37% and RMSE was...
Assimilating external data into crop growth model to improve accuracy of crop growth monitoring and yield estimation has been being a research hotspot in recent years. In this paper, the global optimization algorithm SCE-UA (Shuffled Complex Evolution method-University of Arizona) was used to integrate remotely sensed leaf area index (LAI) with crop growth model EPIC to simulate regional yield, sowing...
Assimilating external data into a crop growth model to improve accuracy of crop growth monitoring and yield estimation has been a research focus in recent years. In this paper, the shuffled complex evolution (SCE-UA) global optimization algorithm was used to assimilate field measured LAI into EPIC model to simulate yield, sowing date and nitrogen fertilizer application amount of summer maize in Huanghuaihai...
Existing work does not provide a flexible dataset-oriented data flow mechanism to meet the complex requirements of scientific Grid workflow applications. In this paper we present a sophisticated approach to this problem by introducing a data collection concept and the corresponding collection distribution constructs, which are inspired by HPF, however applied to Grid workflow applications. Based on...
