The results showed that the nitrogen uptake and remaining in straw increased and the percentage of nitrogen translocation (PNT) from vegetative organs, nitrogen dry matter production efficiency (NDMPE) and nitrogen grain production efficiency (NGPE) decreased with nitrogen increasing. The nitrogen uptake and NGPE decreased when severe water stressed. However, rice not only decreased the nitrogen uptake but also increased the PNT from vegetative organs, NDMPE and NGPE when mild water stressed. There were obvious interactions between nitrogen fertilizer and water management, such as with water stress increasing the effect of nitrogen on increasing nitrogen uptake was reduced and that on decreasing NDMPE was intensified.展开更多

Making region updating occur only when needed can improve the interest management. Typically a static threshold is defined before simulation to trigger the region updating. Now a dynamic threshold is used to trigger region updating , the threshold is adapted by the real-time massage in simulation, named as update lifetime. The result of experiment shows that this policy can overcome the weak point of static threshold and can meet the requirements of bandwidth and simulation correctness.展开更多

Receiver-driven data delivery scheme is used for fast response to data transfers, and a priority based interaction model is adopted to identify the data priority. Three interactive parameters are introduced to prioritize and dynamically manage data queue. The experimental results show that it can ameliorate data delivery ratio and achieve good performance in terms of average delay.展开更多

So, the real-time, interactive visualization aided system of hydropower engineering management is developed.

This new framework must be sensitive to the need for a more theoretical approach to inform disaster and hazard management. Central to this is that the resulting approach cannot be muddled in linear rational and procedural doctrines but appreciate the dynamics of complex nonlinearity of disaster events. By engaging in thought experiment and critical analysis of existing literature, the paper deconstructs the normative paradigm of defining disaster. The end is to inform disaster management and risk reduction intervention and mitigation programmes. The presented alternative approach is sensitive of the need to equally include;spatial, political, social, parameters. These are appreciated as being equally important as those dealing with ecological and economic. The resulting not only include other elements, but also expands the definition to the complex conditions inherent in the origin of phenomena to the interaction of the phenomena with multiple and complex socio-spatial and demographic dynamics, and then appreciating the complex results of this nonlinear interaction. The need for a more substantive definition of disaster underlines the pre-analysis that is necessary for implementation of mitigation and prevention strategies. That disasters are becoming more complex is synonymous with the complexities inherent in post-war development dynamics.展开更多
