The increasingly large ensemble size of modern High-Performance Computing (HPC) systems has drastically increased the possibility of failures. Performance under failures and its optimization become timely important issues facing the HPC community. In this study, we propose an analytical model to predict the application performance. The model characterizes the impact of coordinated checkpointing and...
The decarburization predication model was used to detection of carbon content in RH degasser. Decarburization predication system in RH degasser uses computer technology to analyze on-line data, to study the relation between the carbon content and the difference type molten steel data and processing data and to recognize carbon content of the steel with expert knowledge. The recognizing results can...
The paper presented a novel intra-rate estimation method for H.264/AVC rate control. This method establishes the intra-frame rate-quantization (R-Q) estimation model by using gradient-based picture complexity measure. By this R-Q model, the quantization parameters can be accurately obtained. Simulation results show that by using this scheme, better rate control for Intra-frames.
Trichel streamer pulses have been simulated at various air pressures and humidities. A flux-corrected transport algorithm based on a non-uniform mesh was applied to solve the continuity equations and Poisson's equation in a fluid model to calculate the negative streamer pulse waveforms. The values of the various coefficients for humid air, considered as a mixture of air and water vapor, were estimated...
To solve moving parameters identification problem for deep sea-bed mining robot, estimation model of key parameters is built after the discussion on robot dynamic model and hydraulic system. And a controller based on key parameters estimation model is presented to accomplish the path following task for deep sea-bed mining robot with assumption that the desired path is given. Experiment results on...
