In the coal fired power station, the regulation of the load or the sudden stop operation of the unit in accident may result in water hammer, which would have critical influence on the safety operation of the unit. In this paper the analysis of water dynamic characters and the calculation of the pressure increment were shown, when the water hammer was produced in the system.

The association between dietary fat types and obesity is controversial， and the underlying mechanism remains unclear. This study aimed to evaluate the effect of different dietary fat sources (lard， corn oil or canola oil) on obesity in mice. The results revealed that lard-fed mice showed a lean phenotype， as well as lower serum cholesterol level compared with mice fed corn oil or canola oil. The 16S rRNA gene sequencing showed that the lard-fed mice had higher alpha diversity of gut microbiota. In addition， the lard group had similar relative abundance of Lactobacillus， unclassified＿f＿Lachnospiraceae and Bacteroides compared with the control group. Targeted metabolomics analysis of caecal bile acid (BA) profile suggested the levels of chenodeoxycholic acid (CDCA)， lithocholic acid (LCA)， deoxycholic acid (DCA) and cholic acid (CA) in the lard group were higher than those in the corn oil and canola oil groups. Meanwhile， the levels of BA receptor farnesoid X receptor (FXR) gene in lard-fed mice were higher than vegetable oil groups. These results suggested that lard could reduce the risk of obesity compared with corn oil and canola oil， which may be associated with more balanced gut microbiota and BA composition as well as activated FXR signaling.

第三十九届中国控制会议

作者： xinyuan huang Li Li Jie Chen IEEE IFAC Chinese Academy of Engineering Tongji University the State Key Laboratory of Intelligent Control and Decision of Complex Systems the Chinese Association of Automation the Chinese Artificial Intelligence Society College of Electronics and Information Engineering Tongji University Shanghai Reserach Institute for Intelligent Autonomous Systems

In this paper, we provide a novel scheme to solve the motion planning problem of multi-agent systems under highlevel task specifications. First, linear temporal logic is applied to express the global task specification. Then an efficient and decentralization algorithm is proposed to decompose it into local tasks. Finally, we use control barrier function to synthesize the local controller for each agent under the LTL motion plan safety constraint. Simulation results prove the effectiveness and efficiency of our proposed method.

为了快速、准确地测量植物叶面积,该文提出了基于彩色通道相似性图像分割的植物叶面积测量方法。该文基于彩色图像,利用像素彩色通道的相似性和自适应方法得到的阈值分割叶片区域,并分别统计叶片和参考矩形的像素数,进而计算植物叶面积。试验表明,该方法得到的植物叶片区域更准确,并且对叶片阴影、花斑等具有很强的鲁棒性,错分率为仅为1.23%,具有较高的精度。该方法是一种实用的通过拍照计算植物叶面积的方法,可嵌入到手机等移动设备中。
