CASE STUDY OF DIGITAL AGRICULTURE IN THE OUTSKIRTS OF beijing

第七届亚洲气溶胶会议

作者： Junying Sun1 Yangmei Zhang1 Xiaojing Shen1 2 Xiaochun Zhang1 and Xiaoye Zhang 1 Key Laboratory for Atmospheric Chemistry of CMA Center for Atmosphere Watch and Services Chinese Academy of Meteorological Sciences No.46 Zhongguancun Nandajie beijing 100081 China 1 2 Graduate University of Chinese Academy of Sciences beijing 100049 China

Atmospheric aerosols are receiving increasing attention because of their effect on human health, visibility, acid deposition and global/regional climate. It is well known that unlike the major long-lived gases, aerosols are not distributed uniformly in the atmosphere. Regions downwind of major particulate sources such as deserts, biomass burning areas and large cities often have heavy atmospheric aerosol burdens while other areas in cleaner regions have relatively low aerosol loadings. The composition and size distribution of these particles, and thus their optical properties, vary widely from place to place and over time. To achieve a better understanding of the characteristics, sources and processes of aerosols in beijing, an Aerodyne Aerosol Mass Spectrometer （AMS） was deployed to obtain size-resolved chemical composition of non-refractory submicron particles （NR-PM1） , while SMPS （Scanning Mobility Particle Sizer） and TDMPS （Twin Differential Mobility Particle Sizer） was used to obtain the particle number size distribution in beijing region. The particle loading and chemical composition, chemical-resolved size distributions, number size distribution was discussed. Surface-based measurements of aerosol properties such as size distribution, chemical composition, etc, either at long-term monitoring sites, or specifically as part of intensive field campaigns, could provide essential validation for satellite retrieval, and thus to provide near-global retrievals of aerosol properties.

Science China(Information Sciences) 2024年

作者： Chenggang SHAN Runze GAO Zhen YANG Wei ZHANG Yuanqing XIA 1.School of Artificial Intelligence, Zaozhuang University 2.School of Automation, beijing Institute of Technology School of Artificial Intelligence Zaozhuang University School of Automation Beijing Institute of Technology

As an extension of networked control systems, cloud control systems (CCSs) have emerged as a new control paradigm to improve the service quality of emerging control missions, such as data-driven modeling and automated vehicles. Existing studies have used the workflow-based restructured method to optimize the computation-intensive algorithms in the CCSs. However, the challenges here are how to define and submit these algorithms’ workflows as cloud services and execute these algorithms’ workflows in a containerized manner. Based on these challenges, we propose a containerized solution for the control-algorithm-as-a-service(C3aS) in the CCSs, namely ControlService. It offers the control algorithm as a cloud workflow service and uses a customized workflow engine to realize the containerized execution. First, we employ a cloud workflow representation method to define a control algorithm into an abstract cloud workflow form. Afterward, we provide a cloud service representation of the abstract cloud workflow. Next, we design a workflow engine and submit the cloud service to this workflow engine to implement containerized execution of this cloud service in the CCSs. In the experiment, we discuss the cloud service form and containerized implementation of the subspace identification method. Experimental results show that the proposed ControlService has significant performance advantages in computational time, reduction percentage, and speedup ratio compared with the baseline method.

目的恶意的图像拼接篡改给名誉、法律、政治等带来一系列的挑战,而现有的图像拼接检测算法通常采用参数固定的高通滤波器提取滤波特征进行预处理,没有考虑图像之间的差异。方法本文设计自适应残差模块(adaptive residuals module, ARM)凸显拼接篡改痕迹,将卷积运算后的残差多次拼接,且每次拼接后再利用注意力机制实现通道间的非线性交互。然后,使用通道注意力SE(squeeze and excitation)模块以减少由ARM提取残差特征产生的通道之间信息冗余,并以在图像分类领域获得卓越性能的EfficientNet(high-efficiency network)为骨干网络,提出一种新的图像拼接检测算法。结果实验结果表明,所提算法在CASIA I(CASIA image tampering detection evaluation database),CASIA II,COLUMBIA COLOR,NIST16(NIST special database 16)和FaceForensic++这5个公开数据集上分别取得98.95%,98.88%,100%,100%,88.20%的检测准确率,获得比现有算法更高的准确率。提出的ARM将骨干网络EfficientNet在CASIA II数据集的准确率提高了3.94%以上。结论提出的基于自适应残差的图像拼接检测算法充分考虑图像之间的差异,凸显篡改区域与未篡改区域之间的区别,并获得更好的拼接检测结果。

To describe the case fatality rate of SARS in beijing. Methods Data of SARS cases notified from beijing Center for Disease Control and Prevention （BCDC） and supplemented by other channels were collected. The data were analyzed by rate calculation. Results The case fatality rate of SARS in beijing was 7.66%, and had an ascending trend while the age of cases was getting older, and a descending trend while the epidemic developmem. The case fatality rate in beijing was lower than that in other main epidemic countries or regions. Conclusions The risk of death increases with the increment of age of SARS patients. beijing is successful in controlling and treating SARS.
