Multi-time scale dynamics in power electronics-dominated power systems
Xiaoming YUAN, Jiabing HU, Shijie CHENG
Frontiers of Mechanical Engineering 2017, Volume 12, Issue 3, Pages 303-311 doi: 10.1007/s11465-017-0428-z
Electric power infrastructure has recently undergone a comprehensive transformation from electromagnetics to semiconductors. Such a development is attributed to the rapid growth of power electronic converter applications in the load side to realize energy conservation and on the supply side for renewable generations and power transmissions using high voltage direct current transmission. This transformation has altered the fundamental mechanism of power system dynamics, which demands the establishment of a new theory for power system control and protection. This paper presents thoughts on a theoretical framework for the coming semiconducting power systems.

Dynamic behavior analysis of Taizhou Bridge

Strategic Study of CAE 2010, Volume 12, Issue 8, Pages 83-87
The dynamic behaviors have critical influences on the design of structure dynamics, health monitoring and maintenances. The three- pylon two-span suspension bridge does have different static and dynamic behaviors comparing with traditional one-span suspension bridge. This paper analyzes the dynamic behavior of Taizhou Bridge under construction stage and operation stage based on ANSYS. Some meaningful results have been obtained and can provide references for engineers in the further.

De-scattering and edge-enhancement algorithms for underwater image restoration Research Papers

Frontiers of Information Technology & Electronic Engineering 2019, Volume 20, Issue 6, Pages 862-871 doi: 10.1631/FITEE.1700744
Image restoration is a critical procedure for underwater images, which suffer from serious color deviation and edge blurring. Restoration can be divided into two stages: de-scattering and edge enhancement. First, we introduce a multi-scale iterative framework for underwater image de-scattering, where a convolutional neural network is used to estimate the transmission map and is followed by an adaptive bilateral filter to refine the estimated results. Since there is no available dataset to train the network, a dataset which includes 2000 underwater images is collected to obtain the synthetic data. Second, a strategy based on white balance is proposed to remove color casts of underwater images. Finally, images are converted to a special transform domain for denoising and enhancing the edge using the non-subsampled contourlet transform. Experimental results show that the proposed method significantly outperforms state-of-the-art methods both qualitatively and quantitatively.
