In this study, real-time disease monitoring was conducted on onion which is the most representative crop in Republic of Korea, using an image acquisition system newly developed for the mobile measurement of phenotype. The purpose of this study was to improve the accuracy of prediction of disease and state variables by processing images acquired from monitoring. The image acquisition system was consisted of two parts, a motorized driving system and a PTZ (pan, tilt and zoom) camera to take images of the plants. The acquired images were processed as follows. Noise was removed through an image filter and RGB (red, green and blue) colors were converted to HSV (hue, saturation and value), which enabled thresholding of areas with different colors and properties for image binarization by comparing the color of onion leaf with ambient areas. Four objects with the most significant browning in the onion leaf to the naked eye were selected as the samples for data acquired. The thresholding method with image processing was found to be superior to the naked eye in identifying accurate disease areas. In addition, it was found that the incidence of disease was different in each disease area ratio. As a result, the use of image acquisition system in image processing analysis will enable more prompt detection of any changes in the onion and monitoring of disease outbreaks during the crop lifecycle.

Electric power infrastructure has recently undergone a comprehensive transformation from electromagnetics to semiconductors. Such a development is attributed to the rapid growth of power electronic converter applications in the load side to realize energy conservation and on the supply side for renewable generations and power transmissions using high voltage direct current transmission. This transformation has altered the fundamental mechanism of power system dynamics, which demands the establishment of a new theory for power system control and protection. This paper presents thoughts on a theoretical framework for the coming semiconducting power systems.

FULL TIME-SPACE GOVERNANCE STRATEGY AND TECHNOLOGY FOR CROPLAND NON-POINT POLLUTION CONTROL IN CHINA
《农业科学与工程前沿(英文)》 2023年 第10卷 第4期 页码 593-606 doi: 10.15302/J-FASE-2023522
Ensuring food safety while reducing agricultural non-point source pollution is quite challenging, especially in developing and underdeveloped countries. Effective systematic strategies and comprehensive technologies need to be developed for agricultural non-point source pollution control at the watershed scale to improve surface water quality. In this review, a proposal is made for a full time-space governance strategy that prioritizes source management followed by endpoint water pollution control. The 4R chain technology system is specifically reviewed, including source reduction, process retention, nutrient reuse and water restoration. The 4R chain technology system with the full time-space governance strategy was applied at the scale of an administrative village and proved to be a feasible solution for reducing agricultural non-point source pollution in China. In the future, a monitoring system needs to be established to trace N and P transport. Additionally, new smart fertilizer and intelligent equipment need to be developed, and relevant governance standards and supportive policies need to be set to enhance the efficacy of agricultural non-point source pollution control.

天基信息实时智能服务系统(PNTRC)是多星协同、多网互联的下一代天基信息系统,将广泛应用在卫星通信、导航、遥感等领域。本文针对 PNTRC 建模仿真和效能评估展开研究,分析了系统评估仿真的必要性、需求以及发展趋势,进而支撑PNTRC顶层设计和实施方案论证。针对 PNTRC 动态时变、业务多样、异质异构的特性,对场景可扩展的高效分布式仿真、时空动态分析评估方法、系统体系化建模等关键技术展开详细讨论。基于分布式仿真评估系统,以高分辨率对地遥感业务为例,对比和评估了多个低轨通信星座对遥感业务的传输支持能力。研究结果表明,在遥感业务数据传输过程中,覆盖密集的OneWeb 星座卫星具有更小的网络时延、丢包以及更高的容量和稳定性,但单星容量反而不及覆盖密度较小的“虹云”“鸿雁”星座。本文研究为我国PNTRC可行性论证与工程建设提供了方法和技术手段支撑。
