Preliminary Recommendations on the Suitable Shed Profile for HVDC Station Insulators with Silicone Rubber Housing

Wenjian Ma Bingru Luo Zhao Su Zhenping Dang Z. C. Guan

The selection of suitable shed profiles for station insulators with silicone rubber housings is an important subject for the successful operation of the HVDC and UHVDC systems. This subject has been discussed on a Seminar with a group of invited experts on external insulation. The participants recognized the lack of research results in this area. However, considering the urgent engineering needs for the coming UHVDC projects, after a review of the operational experiences of the existing 500-600 kV HVDC stations, especially the stations in China, the participants concluded the Seminar with preliminary recommendations on the decisive parameters of suitable shed profiles and a test method for shed profile selection. These recommendations are considered to be applicable to vertically installed HVDC station insulators with silicone rubber housing and with relative large diameters. At the same time, the participants encourage and invite utilities, manufacturers, and research institutes to be active on this subject and to provide more reliable test results.

Studies on Sanitary Wastewater Treatment by Down-flow Constructed Wetland

Industrial Safety and Environmental Protection (2009)

Zhao Su

Down-flow constructed wetland is used to treat the sanitary wastewater.The removal rates of CODCr,TN and TP in the system are analyzed.The removal rates of pollutants in the two systems with and without plants are contrasted.It is found that the system can effectively remove CODCr,TN and TP;the concentrations of TN and TP in the inflow almost doesn't affect the outflow and the plants react on the removal process of pollutants.

How to Select the Biding Admixture of Briquette

Sci/tech Information Development & Economy (2005)

Zhao Su

The biding admixture is the key accessory agent that can determine the assortment and the quality of the briquette, the coal with different quality needs different biding admixture, and the briquette of different usage must select corresponding biding mixture. Those briquette manufacturers, which want to product acceptable briquette according to the demand of the market, must determine the raw coal at first, then select the biding admixture and design the production technical process of the briquette based on the requirements of the binding admixture, and at last select the auxiliary briquette production equipment.

STCP: Synergistic Transformer and Convolutional Neural Network for Pansharpening

IEEE Transactions on Geoscience and Remote Sensing (2023)

Zhao Su Yong Yang Shuying Huang Weiguo Wan Jiancheng Sun

Pansharpening is a process of fusing a high-resolution panchromatic (PAN) image with a low-resolution multispectral (LRMS) image to obtain a high-resolution multispectral (HRMS) image. Convolutional neural networks (CNNs) have been commonly utilized in this field because of their remarkable learning capabilities. However, their convolutional operators limit the long-range feature extraction ability of CNN. Meanwhile, the Transformer models have exhibited strong capabilities in modeling long-range representations, but there are shortcomings in modeling local-range feature dependencies. To this end, we propose a novel synergistic transformer and CNN for pansharpening (STCP). First, a parallel U-shaped feature extraction module (PUFEM) is constructed for extracting the features of the LRMS and PAN images, which improves the feature representation ability for the two source images. In the PUFEM, combining the different feature learning capabilities of the CNN and transformer, we design a long-short-range feature integration block (LSFIB) to extract the short-range features and long-range features at different scales in parallel. Then, a channel attention module (CAM)-based feature fusion module (CFFM) is constructed to integrate the features extracted by the PUFEM. Finally, the shallow features from the PAN image are reused to provide detailed features, which are integrated with the fused features from the CFFM to achieve the final pansharpened results. Numerous experiments show that our STCP outperforms some state-of-the-art approaches both subjectively and objectively.

Influence of Low-temperature Heat-treatment on the Structure and Properties of Fe@Ag Composite Particles

Journal of Inorganic Materials (2010)

Zhao Su

In order to reduce the resistivity of Fe@Ag composite particles,the influence of heat-treatment tempera-ture(T) on the structure,resistivity and magnetic properties of the Fe@Ag composite particles,and the shielding ef-fectiveness(SE) of the electromagnetic shielding rubber containing the Fe@Ag composite particles were studied.The results show that with heat-treatment temperature increasing from 120℃ to 170℃,the Fe@Ag composite particles heat-treacted at 140℃ have the most compact silver-shells and the lowest volume resistivity,while the saturation mag-netization almost keeps unchanged.The electromagnetic shielding rubber containing the Fe@Ag composite particles heat-treated at 140℃ has SE of -28 dB to -53 dB,which is -10 dB to -15 dB higher than that of the particles without heat-treatment.The morphology evolution and related property changes with T are reasonably explained by the interface wetting theory and crystal growth theory.Low-temperature heat-treatment provides a simple and convenient approach to obtain electromagnetic shielding fillers with high performance.

An edge detection algorithm for mine roadway image

Zhao Su

In view of problem of bad edge extraction effect when traditional Canny algorithm processes fuzzy mine roadway image,the paper proposed an edge detection algorithm for mine roadway image based on wavelet transform and Canny algorithm.The algorithm firstly makes wavelet decomposition for original mine roadway image to obtain low-frequency image and high-frequency image,so as to avoid influence of fuzzy image on edge detection effect.Then it uses Canny algorithm to calculate first order differences of low-frequency image and high-frequency image to obtain gradient images of low-frequency image and high-frequency image and obtains edge images of low-frequency image and high-frequency image through calculating the maximum value of local gradient.When edge image of high-frequency image has discontinuity point,it detects eight-point neighborhood of the point in edge image of low-frequency image to find connection point to obtain complete edge detection image of mine roadway.The experiment result showed that the algorithm can detect more edge points of image with better edge connection effect comparing with traditional Canny algorithm.

DCNP: Dual-Information Compensation Network for Pansharpening

IEEE Geoscience and Remote Sensing Letters (2022)

Yong Yang Zhao Su Shuying Huang Weiguo Wan Wei Tu

To reduce the loss of detail and spectral information during the network propagation and better extract detail and spectral features at different scales, a novel dual-information compensation network for pansharpening (DCNP) is proposed for fusing multispectral (MS) and panchromatic (PAN) images. In the network, the domain-specific knowledge is considered to design our DCNP architecture by focusing on the two aims of the pansharpening: spatial and spectral preservation. Specifically, a cascaded U-shaped structure is constructed to improve the feature representation ability of the network. To preserve more spatial details in the pansharpened image, the details of the PAN image are extracted based on Laplacian operator and then compensated into the network. Furthermore, for spectral preservation, the MS image is conducted by the transposed convolution as the compensation information of the network. Experiments on the full- and reduced-scale data indicate that the proposed DCNP achieves significant improvement over state-of-the-art methods in terms of subjective and objective evaluation. Specifically, DCNP improves the PSNR and ERGAS metrics by 12.9% and 44.5% respectively compared to the deep learning-based approach with the best average values on Pléiades.
