A new HPC technology was developed in terms of the domain decomposition along time-axis, namely time decomposition method (TDM), to solve all time steps (or a subdivision of all time steps) simultaneously to achieve better scalability, instead of solving a transient problem sequentially one time-step by one time-step. For practical applications, we further introduced two TDM models: one is the Periodic...
Autonomous underwater vehicles (AUVs) work in complex marine environments, and sensors play an important role in AUV systems. Therefore, research on sensor failure diagnosis technology is important for improving the reliability of AUV systems. In this paper, a new method combining phase space reconstruction and extreme learning machine (ELM) is proposed. This method is applied to predict sensor output...
In this paper, we present one simplify underwater image restoration model combined with Total variation (TV) regularized Richardson-Lucy (RL) algorithm. Poor visibility in the sea and the variations in the illumination, viewpoints, etc., have been comprehensively taken into consideration for image restoration. An adaptive image restoration strategy by Improvement signal-to-noise ratio (ISNR) is then...
In this paper, the consistent fish tracking strategies have been present for the underwater surveillance system with multiple static cameras in the overlapping field of views (FOV). The discriminative appearance model has been first introduced to distinguish the swimming fish and the background by the superpixel. The centroid coordinate homographic mapping and the Speeded Up Robust Features (SURF)...
Autonomous underwater vehicle (AUV) is developed as a powerful tool with capability of autonomous navigation to conduct benthal survey and exploration. It's a kind of expensive equipment and experimental data obtained in one voyage is also very important. So an on-board self-rescue system is indispensable to ensure AUV escaping from dangers and rising up to the surface safely. In this paper a self-rescue...
In the task running environment oriented to communication field applications, the characteristcs of a task are commonly undeterministic and unpredictable due to the unsteadiness of communication networks. It is necessary to apply fuzzy concept and theory into the embedded soft real-time task scheduling field. In this paper, we presented a fuzzy scheduling model based on multi-characteristics of a...
