为优化都市圈城际出行结构,提高轨道交通运营效益,利用基于Logit动态的演化博弈模型揭示了都市圈客运走廊城际通勤方式选择的动态过程.模型考虑了出行时间、费用、拥堵、感知收益等影响因素,并利用南京都市圈宁句客运走廊出行调查数据进行了计算分析.结果表明,随着纯电汽车的普及,有32.2%的出行者从轨道交通转向小汽车出行.减少轨道交通在途时间成本与降低轨道交通票价均能吸引出行者选择轨道交通出行,但前者的效果更好.同时,随着轨道交通出行比例的增加,减少轨道交通在途时间成本所吸引的出行者数量呈先逐渐增加后快速减少的趋势.

针对齿轮箱故障诊断精度低以及深度神经网络模型对计算机硬件要求高等问题,提出了Shuffle-ECANet网络模型用于齿轮箱故障诊断。该模型以轻量化神经网络ShuffleNet V2为基础,在保留网络轻量化结构的同时对网络模型进行了优化,采用Gelu激活函数增强了模型非线性变换能力,嵌入高效通道注意力(efficient channel attention, ECA)模块以提高网络性能。深度可分离卷积提高了网络模型的运算效率,通道混洗技术使得信息更加流通,提高了特征表达能力。实验结果表明,本文所提网络模型在保证轻量化的同时适用于不同噪声工况的齿轮箱故障诊断,在原信号下可达99.6%的诊断准确率,在添加了信噪比为-8 dB的高斯白噪声下可达92.7%的诊断准确率。本文所提方法为神经网络更好地应用于齿轮箱故障诊断提供了一条新的途经。

Interleukin-6, desmosome and tight junction protein expression levels in reflux esophagitis-affected mucosa

World Journal of Gastroenterology 2009年第29期15卷 3621-3630页

AIM： To investigate the correlation between the expression levels of interleukin （IL）-6 and proteins in tight junctions （TJs） in the esophageal mucosa of rats modeling different types of reflux esophagitis （RE）, and the ability of aluminum phosphate to protect against RE-induced mucosal damage via these proteins. METHODS： Male SPF Wistar rats aged 56 d were divided randomly into acid RE, alkaline RE, mixed RE, and control groups. Various surgical procedures were performed to establish rat models of acid RE. At 14 d after the procedure, some of the rats started aluminum phosphate treatment. Transmission electron microscopy （TEM） was used to observe the morphological features of TJs and desmosomes in the esophageal epithelium. Immunohistochemical methods and Western blotting were used to measure expression of claudin 1, occludin, ZO-1, JAM-l, DSG-1 and IL-6; reverse transcription polymerase chain reaction （RT- PCR） was used to measure expression of mRNA of claudin 1, occludin, ZO-1, JAM-1, DSG-1 and IL-6. RESULTS： At day 14 alter the procedures, an RE model was established in all subsequently sacrificed rats of groups A, B and C. By both gross and microscopic observation, the mucosa was damaged and thickened as the disease progressed. With TEM observation, a widened intercellular space was noticed, with significantly fewer desmosomes. Immunohistochemistry showed significantly higher levels of all proteins in all RE models compared to control rats at 3 d after operation （65.5% ± 25.6% vs 20.5% ± 2.1%, P 〈 0.05, respectively）. At 14 d after operation, along with continuing hyperplasia in the basal layer, the expression of TJ proteins in individual cells gradually decreased （12.4% ± 2.1% vs 20.5% ± 2.1%, P 〈 0.05, respectively）. Western blottings and RT-PCR showed a directly proportional increase in IL-6 levels in relation to TJ proteins, as compared to controls （0.878 ± 0.024 vs 0.205 ± 0.021 and 0.898±0.022 vs 0.205 ± 0.021, P 〈 0.05, respectively）.

Control 5.0: From Newton to Merton in Popper's Cyber-Social-Physical Spaces

作者： fei-yue Wang IEEE State Key Laboratory of Management and Control for Complex Systems Institute of Automation Chinese Academy of Sciences (SKL-MCCS CASIA) Research Center of Computational Experiments and Parallel Systems The National University of Defense Technology

The future of control in cyberspace of parallel worlds is discussed. It argues for the coming age of Control 5.0,the control technology for the new IT capable of dealing with artificial worlds with VR, AR, AI and robotics. The discipline of automation needs a new interpretation of its core knowledge and skill set of modeling, analysis, and control for cyber-socialphysical systems, and a paradigm shift from Newtonian Systems with Newton's Laws or Big Laws with Small Data to Mertonian Systems with Merton's Laws or Small Laws with Big Data.

Determination of Polynomial Degree in the Regression of Drug Combinations

引用

IEEE/CAA Journal of Automatica Sinica 2017年第1期4卷 41-47页

作者： Boqian Wang Xianting Ding fei-yue Wang School of Biomedical Engineering Shanghai Jiao Tong University IEEE State Key Laboratory of Management and Control for Complex Systems Institute of Automation Chinese Academy of Science (SKL-MCCS CASIA) Research Center of Computational Experiments and Parallel Systems National University of Defense Technology

Studies on drug combinations are becoming more and more popular in the past few decades, with the development of computer and algorithms. One of the most common methods in optimizing drug combinations is regression of a polynomial model based on certain number of experimental observations. In this paper, we study how to determine the degree of polynomials in different circumstances of drug combination optimization. Using cross-validation, we have found that in most cases, a high degree results in failures of accurate prediction, named overfitting. An anti-noise test has also revealed that polynomial model with high degree tends to be less resistant to random errors in the observations. © 2014 Chinese Association of Automation.

Accurate and Robust Eye Center Localization via Fully Convolutional Networks

引用

IEEE/CAA Journal of Automatica Sinica 2019年第5期6卷 1127-1138页

作者： Yifan Xia Hui Yu fei-yue Wang the School of Creative Technologies University of PortsmouthPortsmouthPO1 2DJUK the State Key Laboratory of Management and Control for Complex Systems Institute of AutomationChinese Academy of SciencesBeijing 100190China

Eye center localization is one of the most crucial and basic requirements for some human-computer interaction applications such as eye gaze estimation and eye tracking. There is a large body of works on this topic in recent years, but the accuracy still needs to be improved due to challenges in appearance such as the high variability of shapes, lighting conditions, viewing angles and possible occlusions. To address these problems and limitations, we propose a novel approach in this paper for the eye center localization with a fully convolutional network(FCN),which is an end-to-end and pixels-to-pixels network and can locate the eye center accurately. The key idea is to apply the FCN from the object semantic segmentation task to the eye center localization task since the problem of eye center localization can be regarded as a special semantic segmentation problem. We adapt contemporary FCN into a shallow structure with a large kernel convolutional block and transfer their performance from semantic segmentation to the eye center localization task by *** experiments show that the proposed method outperforms the state-of-the-art methods in both accuracy and reliability of eye center localization. The proposed method has achieved a large performance improvement on the most challenging database and it thus provides a promising solution to some challenging applications.
