Results from this renewal project will improve the ability of climate models in predictions of El Nino-Southern Oscillation(ENSO),its impacts and in projections of future changes in ENSO activity.It is anticipated that the theoretical and methodological t

隨著航空航海技術的發展，流動控制已成為流體力學的前沿和熱點問題,控制的方法也多種多樣。而各種控制方法有著各自的優缺點,對于航空、航海等相關領域，單一的控制方法已逐漸無法滿足實際需求。為了揚長避短，在不同的時刻、位置等條件下需采用不同的復合方式。本項目擬以理論研究和數值計算為主，并輔以實驗驗證，展開以減阻為目的的，復合激勵板控制湍流邊界層的研究。內容包括：1.電磁-溝槽復合控制的數值研究。揭示在不同雷諾數條件下的電磁-溝槽復合控制中，湍流流場的變化特征和耦合調制機理。2.復合控制的流動優化研究。從空間和時間

降雨引發的淺層滑坡具有區域性的群發效應，能夠在短時間內造成大量的災難性損失。降雨過程的動態性及多樣性直接影響著滑坡發生的位置及強度。本項目從降雨對淺層滑坡演化過程的作用機理入手，將滑坡的地質機理和變形失穩過程考慮到滑坡危險性評價的研究中，確定區域淺層滑坡災害強度量化方法，在武陵山區滑坡災害調查數據統計分析的基礎上，建立土體結構的概化模型，分析不同土體結構模型的入滲特征，研究坡體不同部位的及其相鄰坡體坡體之間的雨水運動規律；進行室內物理模型試驗，構建降雨入滲條件下淺層滑坡的力學計算模型，提出淺層滑坡變形失穩

This is funding to support a Doctoral Consortium(workshop)of approximately 10 promising graduate students(8 from the United States and 2 from abroad,the latter to be supported by Google),along with 5 distinguished research faculty.The event will take plac

This project develops new technology toward Video2Sim:automatically converting a video into a virtual world,where scenes are reconstructed,actions are re-enacted,and alternative outcomes are simulated by a computer.Such a system does not yet exist due to

This project aims to provide the first global-scale constraints on temperature and dynamics of the free-troposphere-which comprises altitudes ranging from about 2-18 km.Specifically,the researcher will use new isotopic measurements and 3 Dimensional(3D)gl

We plan to continue to develop and assess the efficacy of novel approaches for the treatment of malignant disease based on studies in dogs with spontaneously occurring malignancies. Studies in dogs with malignant lymphoma have shown that some dogs treated

The long range objectives of this project are to characterize fundamental properties of the replication-specific mammalian DNA polymerase alpha (pol alpha) and its structural gene and to discern within them unique sites and/or mechanisms which can be expl

Mammalian spermatogenesis is a hormone-dependent process regulated mainly by follicle-stimulating hormone (FSH) and testosterone (T). The effects of these hormones on germ cell (Gc) differentiation are believed to be indirect, mediated through the somati
