Extension of Giurgiu Port on Lower Danube

引用

Journal of Geological Resource and Engineering 2019年第1期7卷 17-31页

作者： radu-Constantin Cazamir Structural Engineering and Technology Co. Ltd Bucharest 021371 Romania

The paper deals with the construction works devoted to extending and upgrading the port functions to the highest European Standards. The Port of Giurgiu is located on the left bank of the Danube River, at the 493 km, and also at 65 km south of Bucharest, the Capital of Romania. Giurgiu is one of the Romanian largest Danubian Ports. Advanced computer programs were used in design. An active monitoring system, regarding the pre-existing constructions on the site, directly influenced by the excavations was also used. The adopted solutions for infrastructure were dependent by the monitoring results of construction site. The weak foundation conditions as well as the proximity of some existing buildings arouse unexpected obstacles difficult to overpass. However, by a perfect human cooperation all targets were finally reached.

While recent years have witnessed a dramatic upsurge of exploiting deep neural networks toward solving image denoising,existing methods mostly rely on simple noise assumptions,such as additive white Gaussian noise(AWGN),JPEG compression noise and camera sensor noise,and a general-purpose blind denoising method for real images remains *** this paper,we attempt to solve this problem from the perspective of network architecture design and training data ***,for the network architecture design,we propose a swin-conv block to incorporate the local modeling ability of residual convolutional layer and non-local modeling ability of swin transformer block,and then plug it as the main building block into the widely-used image-to-image translation UNet *** the training data synthesis,we design a practical noise degradation model which takes into consideration different kinds of noise(including Gaussian,Poisson,speckle,JPEG compression,and processed camera sensor noises)and resizing,and also involves a random shuffle strategy and a double degradation *** experiments on AGWN removal and real image denoising demonstrate that the new network architecture design achieves state-of-the-art performance and the new degradation model can help to significantly improve the *** believe our work can provide useful insights into current denoising *** source code is available at https://***/cszn/SCUNet.
