| 1 | Fuzziness parameter selection in fuzzy c-means: The perspective of cluster validation显示文摘Fuzzy c-means(FCM) algorithm is an important clustering method in pattern recognition, while the fuzziness parameter, m, in FCM algorithm is a key parameter that can significantly affect the result of clustering. Cluster validity index(CVI) is a kind of criterion function to validate the clustering results, thereby determining the optimal cluster number of a data set. From the perspective of cluster validation, we propose a novel method to select the optimal value of m in FCM, and four well-known CVIs, namely XB, VK, VT, and SC, for fuzzy clustering are used. In this method, the optimal value of m is determined when CVIs reach their minimum values. Experimental results on four synthetic data sets and four real data sets have demonstrated that the range of m is [2, 3.5] and the optimal interval is [2.5, 3]. | ZHOU KaiLe FU Chao YANG ShanLin | 2014 | Science China(Information Sciences)2014，57，11： | 9 |
| 2 | Ecological Harmony:Core Concept for the Construction of Urban Landscape Architecture显示文摘On the basis of analyzing the narrow sense and broad sense of landscape architecture,classical gardens and modern landscape architecture,the authors proposed functions of landscape architecture,and that highquality landscape architecture designs should demonstrate ecological,social and aesthetic functions.By combining theoretical analysis and practical experience,it was verified that urban landscape architecture has to integrate ecological,social and aesthetic functions to manifest its social value to the most. | ZHOU Yujue ZHANG Kailing | 2013 | Journal of Landscape Research2013，5，6： | 2 |

| 4 | Energy storage resources management:Planning,operation,and business model显示文摘With the acceleration of supply-side renewable energy penetration rate and the increasingly diversified and complex demand-side loads,how to maintain the stable,reliable,and efficient operation of the power system has become a challenging issue requiring investigation.One of the feasible solutions is deploying the energy storage system(ESS)to integrate with the energy system to stabilize it.However,considering the costs and the input/output characteristics of ESS,both theinitial configuration process and the actual operation process require efficient management.This study presents a comprehensive reviewof managing ESs from the perspectives of planning,operation,and business model.First of all,in terms of planning and configuration,it is investigated from capacity planning,location planning,as well as capacity and location combined planning.This process is generally the first step in deploying ESS.Then,it explores operation management of ESS from the perspectives of state assessment and operation optimization.The so-called state assessment refers to the assessment of three aspects:The state of charge(SOC),the state of health(SOH),and the remaining useful life(RUL).The operation optimization includes ESS operation strategy optimization and joint operation optimization.Finally,it discusses the business models of ESS.Traditional business models involve ancillary services and load transfer,while emerging business models include electric vehicle(EV)as energy storage and shared energy storage. | Kaile ZHOU Zenghui ZHANG Lu LIU Shanlin YANG | 2022 | Frontiers of Engineering Management2022，9，3： | 1 |
| 5 | Study on the Resistance Levels of Different Echinochloa crusgalli Populations to Penoxsulam and Bispyribac-sodium显示文摘[Objectives]This study was conducted to screen the resistance of Echinochloa crusgalli in some paddy fields in Changde City,Yiyang City and Yueyang City in Hunan Province to penoxsulam and bispyribac-sodium.[Methods]The resistance to penoxsulam and bispyribac-sodium was screened in 11 E.crusgalli populations collected from rice production areas in Changde,Yiyang and Yueyang Cities,Hunan Province,and the resistance level of population HU-2 to penoxsulam was determined.[Results]HU-1 to HU-6 and HU-8 A,a total of seven populations showed high levels of resistance to penoxsulam and bispyribac-sodium.The resistance level of population HU-2 to penoxsulam was extremely high;population HU-7 showed low-level resistance to both drugs;HU-11 population showed low-level resistance to penoxsulam and was susceptible to bispyribac-sodium;and populations HU-8 and HU-9 were susceptible to penoxsulam and bispyribac-sodium.[Conclusions]This study provides a technical basis for the rational use of penoxsulam and bispyribac-sodium and the selection of control chemicals for E.crusgalli in paddy fields. | Qi LEI Bingjie LIU Jingbo LI Yunyun ZHOU Kailing PENG Chenzhong JIN Xiu LIU Kaifa GUO Guiying LIU | 2022 | Agricultural Biotechnology2022，11，4： | 0 |
| 6 | Cause-related Marketing Strategy in Supply Chain Considering Quality Differentiation显示文摘Cause-related marketing(CRM),as an organic combination of marketing and corporate social responsibility(CSR),has been widely used in the supply chain.However,the existing literature rarely studies the CRM strategy the in the supply chain.This paper explores the pricing decisions and CRM strategy of supply chain members by examining a supply chain system consisting of a manufacturer and a retailer,where the manufacturer produces two quality differentiated products.By developing a Stackelberg model for three scenarios,including the No CRM strategy,CRM strategy for the high-quality product,and CRM strategy for the low-quality product,this paper finds that the CRM strategy will result in higher wholesale and sales prices for the cause-related product.In addition,consumers’pro-sociality and the degree of product quality differentiation are critical to the manufacturer’s choice of CRM strategy.When the quality difference differs significantly,the manufacturer should implement CRM for the high-quality product in a market with low consumer pro-sociality and for the low-quality product in a market with high consumer pro-sociality;when the product quality difference is slight,the manufacturer should choose to implement CRM for the low-quality product regardless of consumer’s pro-sociality.Furthermore,the model is extended to that the retailer implements the CRM strategy and a retailer-led supply chain.The results indicate that CRM strategy in the supply chain is not influenced by the implementing entity or the supply chain leader. | Guangye Xu Hui Liu Kaile Zhou Xumei Zhang | 2023 | Journal of Systems Science and Systems Engineering2023，32，2： | 0 |
