Side scan sonar imaging is one of the advanced methods for seabed study. In order to be utilized in other projects, such as ocean engineering, the image needs to be classified according to the distributions of different classes of seabed materials. In this paper, seabed image is classified according to BP neural network, and. Genetic Algorithm is adopted in train network in this paper. The feature vectors are average intensity, six statistics of texture and two dimensions of fractal. It considers not only the spatial correlation between different pixels, but also the terrain coarseness. The texture is denoted by the statistics of the co-occurrence matrix. Double Blanket algorithm is used to calculate dimension. Because a uniform fractal may not be sufficient to describe a seafloor, two dimensions are calculated respectively by the upper blanket and the lower blanket. However, in sonar image, fractal has directivity, i. e. there are different dimensions in different direction. Dimensions are different in acrosstrack and alongtrack, so the average of four directions is used to solve this problem. Finally, the real data verify the algorithm. In this paper, one hidden layer including six nodes is adopted. The BP network is rapidly and accurately convergent through GA. Correct classification rate is 92.5 % in the result.

After about 10 years' runing of the LCC (DTRC, USA) and the HYKAT( HSVA,Germany) , another new large cavitation channel with low background noise is to be in operation inchina Ship Scientific research center(CSS-RC), Wuxi, china. The important specific properties of thechannel are the large test section (2. 0 m in height, 2. 2 m in width and 10. 5 m in length) , themaximum speed of more than 15 m/s, the low turbulence level, the low background noise of the wholefacility, together with the new noise measurement system. So large scale models can be tested withonly minor wall effects and at high Renolds numbers, and the pretentious acoustical measurements canbe performed. This paper describes the features of the new channel and the first test resultsobtained during extensive calibration and validation.

The role of Chinese expert consensus in standardization and improvement of the clinical diagnosis and treatment of inflammatory bowel disease (IBD) is self-evident. As clinical and basic research in china becomes standardized under a better understanding of IBD, more data on Chinese patients have become available to develop a consensus and guideline. This guideline, collaboratively developed by the IBD Group, Chinese Society of Gastroenterology, incorporates the latest international consensus statements, domestic research findings, and practical considerations, as an update based on the 2018 Chinese consensus on IBD management. The IBD guideline consists of two parts: ulcerative colitis (UC) and Crohn's disease, and this manuscript presented the UC part. The evidence used in this guideline was collected and analyzed by the standard of guideline, and the contents were organized as problem statements, for clarity. The formulation of this guideline aimed to reflect the latest progress in IBD, providing comprehensive and valuable guidance for the clinical management of IBD.
