| 1 | Gini Coefficient-based Task Allocation for Multi-robot Systems With Limited Energy Resources显示文摘Nowadays, robots generally have a variety of capabilities, which often form a coalition replacing human to work in dangerous environment, such as rescue, exploration, etc. In these operating conditions, the energy supply of robots usually cannot be guaranteed. If the energy resources of some robots are consumed too fast, the number of the future tasks of the coalition will be affected. This paper will develop a novel task allocation method based on Gini coefficient to make full use of limited energy resources of multi-robot system to maximize the number of tasks. At the same time, considering resources consumption,we incorporate the market-based allocation mechanism into our Gini coefficient-based method and propose a hybrid method,which can flexibly optimize the task completion number and the resource consumption according to the application contexts.Experiments show that the multi-robot system with limited energy resources can accomplish more tasks by the proposed Gini coefficient-based method, and the hybrid method can be dynamically adaptive to changes of the work environment and realize the dual optimization goals. | Danfeng Wu Guangping Zeng Lingguo Meng Weijian Zhou Linmin Li | 2018 | IEEE/CAA Journal of Automatica Sinica2018，5，1： | 6 |
| 2 | Efficient synthesis of poly(oxymethylene) dimethyl ethers over PVP-stabilized heteropolyacids through self-assembly显示文摘A series of polyvinylpyrrolidone-stabilized heteropolyacids(PVP-HPAs)are generated by self-assembly of HPAs and PVP in methanol.The PVP-HPAs are then employed as catalysts for the synthesis of poly(oxymethylene)dimethyl ethers(DMMn,n1)by the methanolysis of trioxane.The results suggest that the acidity of PVP-HPAs is tunable by changing the ratio of PVP and HPAs,which is a key factor for the selectivity of the DMMn product.By optimizing the composition and reaction conditions,two types of PVP-HPA,PVP-phosphotungstic acid(PVP-HPW)in a PVP/HPW ratio of 1/4:1 and PVP-silicotungstic acid(PVP-HSi W)in a PVP/HSi W ratio of 1/4:3/4,respectively afford 52.4%and 50.3%yields of DMM2–5.The optimized catalysts are reusable for a minimum of 10 times without a significant drop in performance. | Xiaolong Fang Jin Chen Linmin Ye Haiqiang Lin Youzhu Yuan | 2015 | Science China Chemistry2015，58，1： | 4 |

| 4 | Availability Analysis of a Repairable Series-Parallel System with Redundant Dependency显示文摘This paper investigates the steady-state availability of a repairable series-parallel system with redundant dependency.The different types of components and repairmen are taken into account,the failure rate of the operating component varies as the number of other failed components and the repair rate of the failed component is constant in each parallel redundant subsystem.To quantify the redundant dependency,a modified failure dependence function is introduced to determine the failure rate of the components in each subsystem.Markov theory and matrix analysis method are used to get the steady-state probability vector of each subsystem and the steady-state availability of the entire system.A numerical example is presented to illustrate the obtained results and to analyze the effect of redundant dependency class on the system availability. | HU Linmin YUE Dequan MA Zhanyou | 2020 | Journal of Systems Science & Complexity2020，33，2： | 2 |
| 5 | Dose inter-comparison studies for ^(60)Co gamma-ray and electron beam irradiation in the year 2002显示文摘Dose inter-comparison studies for Co γ-ray and 10 MeV electron beam irradiation were carried out 60 from July to October in 2002. The purpose of the studies was to check the reliability of the alanine-PE film dosime- ters made by CIAE, which will be used as transfer standard dosimetry system mainly for electron beam irradiation. The expanded uncertainty of CIAE alanine/EPR dosimetry system was 4.1% for doses not higher than 10 kGy and 5.4% for those above 10 kGy (k=2). CIAE alanine-PE film dosimeters were sent to JAERI, RISO (National Labora- tory in Denmark) and INCT respectively, which were irradiated by Co gamma-rays or electron beams in each labo- 60 ratory. The irradiated dosimeters were then sent back to CIAE for electron paramagnetic resonance (EPR) analysis. The agreements were obtained to be ±1.9% for gamma-ray dose measurement and ±4.3% for electron beam dose measurement, which were all within the combined uncertainty of the reference and CIAE alanine/EPR dosimetry system. Furthermore, the overall mean ratio was found to be 0.995 with 1.8% in the coefficient of variation (CV). The preliminary inter-comparison studies indicated that CIAE film alanine/EPR dosimetry system had the potential to be used as a transfer dosimetry system for high dose measurement. | LINMin TakujiKOJIMA ZofiaPEIMEL-STUGLIK CHENYun-Dong CUIYing CHENKe-Sheng LIHua-Zhi XIAOZhen-Hong SlawomirFABISIAK | 2004 | Nuclear Science and Techniques2004，15，3： | 2 |

| 10 | Yttrium chloride-modified Au/AC catalysts for acetylene hydrochlorination with improved activity and stability显示文摘The addition of yttrium chloride(YCl_3) to an activated carbon-supported Au catalyst(Au/AC) can markedly promote the catalytic performance of acetylene hydrochlorination to the vinyl chloride monomer(VCM), The structure and physicochemical features of the YCl_3-modified catalysts(Y-Au/AC)were measured by X-ray diffraction, X-ray photoelectron spectroscopy, temperature-programmed reduction, C_2 H_2-temperature programmed desorption, and scanning transmission electron microscopy.The presence of YCl_3 was found suppressing the reduction of highly oxidized Au^(δ+)(δ=1,3) to metallic Au^0 dependently and thus retard the agglomeration of Au nanoparticles during the reaction. In addition,the additive of YCl_3 to the Au/AC catalyst greatly inhibits the coke deposition on the catalyst surface. The optimized catalyst with an atomic ratio of Y/Au = 5(1 wt% Au loading weight) yields an 87.8% acetylene conversion and almost 100% selectivity for VCM under the reaction of GHSV(C_2 H_2) = 800 h^(-1) at 180 ℃.The durability test indicates that the 5 Y-1 Au/AC catalyst maintains high catalytic activity for more than2300 h at 30 h^(-1) GHSV(C_2 H_2) and 180 ℃, indicating great promise as a non-mercury catalyst for PVC manufacture. | Jinhuo Ke Yuxin Zhao Yan Yin Kun Chen Xinping Duan Linmin Ye Youzhu Yuan | 2017 | Journal of Rare Earths2017，35，11： | 1 |
| 11 | Efficient low-temperature soot combustion by bimetallic Ag–Cu/SBA-15 catalysts显示文摘In this study, the effects of copper(Cu) additive on the catalytic performance of Ag/SBA-15 in complete soot combustion were investigated. The soot combustion performance of bimetallic Ag–Cu/SBA-15 catalysts was higher than that of monometallic Ag and Cu catalysts. The optimum catalytic performance was acquired with the 5 Ag_1-Cu_(0.1)/SBA-15 catalyst, on which the soot combustion starts at T_(ig)= 225°C with a T_(50)= 285°C. The temperature for 50% of soot combustion was lower than that of conventional Ag-based catalysts to more than 50°C(Aneggi et al., 2009). Physicochemical characterizations of the catalysts indicated that addition of Cu into Ag could form smaller bimetallic Ag–Cu nanolloy particles, downsizing the mean particle size from 3.7 nm in monometallic catalyst to 2.6 nm in bimetallic Ag–Cu catalyst. Further experiments revealed that Ag and Cu species elicited synergistic effects, subsequently increasing the content of surface active oxygen species. As a result, the structure modifications of Ag by the addition of Cu strongly intensified the catalytic performance. | Zhaojun Wen Xinping Duan Menglin Hu Yanning Cao Linmin Ye Lilong Jiang Youzhu Yuan | 2018 | Journal of Environmental Sciences2018，30，2： | 1 |

| 17 | Synergistic effects of bimetallic Cu-Fe/SiO_2 nanocatalysts in selective hydrogenation of diethyl malonate to 1,3-propanediol显示文摘Cu_x-Fe_y/SiO_2 catalysts were prepared using urea-assisted sol-gel method.The structure and physicochemical properties of the catalysts were characterized using N_2 adsorption-desorption,transmission electron microscopy,H_2-temperature-programmed reduction,powder X-ray diffraction,and X-ray photoelectron spectroscopy.Compared with monometallic Cu or Fe catalysts,the bimetallic Cu_x-Fe_y/SiO_2 catalysts exhibited enhanced catalytic performance for the selective hydrogenation of diethyl malonate to1,3-propanediol.The bimetallic catalyst with an optimal Cu/Fe atomic ratio of 2 exhibited the highest activity,which yielded 96.3%conversion to diethyl malonate and 93.3%selectivity to 1,3-propanediol under the optimal reaction conditions.Characterization results revealed that interactions between Cu and Fe contributed to the improvement of diethyl malonate conversion and selectivity to 1,3-propanediol.The X-ray photoelectron spectroscopy results revealed that the addition of appropriate amount of Fe species enhanced the reduction of Cu^(2+) species,thereby increasing the Cu° species on the surface of bimetallic catalyst.It led to a better chemisorption capacity of hydrogen and further promoted of the activation of hydrogen molecule.The ethyl acetate temperature-programmed desorption results indicated that the FeO_x species provided the additional adsorption sites for substrate molecules,and they activated the C=O bond.The improved catalytic performance of bimetallic Cu_x-Fe_y/SiO_2 catalyst was mainly attributed to the synergistic effect between Cu° and FeO_x species. | Le He Xiaoxiao Gong Linmin Ye Xinping Duan Youzhu Yuan | 2016 | Journal of Energy Chemistry2016，25，6： | 1 |
