| 1 | 灰色关联和证据理论在故障识别中的应用和改进显示文摘针对复杂检测环境下传感器获得的特征信息具有不确定性和模糊性等问题,提出了利用熵权灰色关联算法获得基本可信度赋值函数(BPAF).根据基于证据理论的信息融合方法,设计了单传感器多量测周期时域融合和多传感器空域融合的二级证据融合算法,采用基于可信度的判决方法作为故障检测和识别依据.熵权方法解决了灰色关联算法中特征权重的选取问题,二级证据融合算法提高复杂环境下识别结果的准确率.仿真结果表明,这种方法比一般的故障识别算法具有更高的识别率、更强的鲁棒性和更广的适用性,是复杂环境下故障模式识别的一种正确可行的新方法. | 林云 李一兵 Ruolin Zhou | 2011 | 应用基础与工程科学学报2011，19，2： | 10 |
| 2 | Automatic Modulation Recognition Based on CNN and GRU显示文摘Based on a comparative analysis of the Long Short-Term Memory(LSTM)and Gated Recurrent Unit(GRU)networks,we optimize the structure of the GRU network and propose a new modulation recognition method based on feature extraction and a deep learning algorithm.High-order cumulant,Signal-to-Noise Ratio(SNR),instantaneous feature,and the cyclic spectrum of signals are extracted firstly,and then input into the Convolutional Neural Network(CNN)and the parallel network of GRU for recognition.Eight modulation modes of communication signals are recognized automatically.Simulation results show that the proposed method can achieve high recognition rate at low SNR. | Fugang Liu Ziwei Zhang Ruolin Zhou | 2022 | Tsinghua Science and Technology2022，27，2： | 5 |
| 3 | Weighted Sparse Image Classification Based on Low Rank Representation显示文摘The conventional sparse representation-based image classification usually codes the samples independently,which will ignore the correlation information existed in the data.Hence,if we can explore the correlation information hidden in the data,the classification result will be improved significantly.To this end,in this paper,a novel weighted supervised spare coding method is proposed to address the image classification problem.The proposed method firstly explores the structural information sufficiently hidden in the data based on the low rank representation.And then,it introduced the extracted structural information to a novel weighted sparse representation model to code the samples in a supervised way.Experimental results show that the proposed method is superiority to many conventional image classification methods. | Qidi Wu Yibing Li Yun Lin Ruolin Zhou | 2018 | Computers, Materials & Continua2018，，7： | 2 |
| 4 | From Earth to Space:A First Deployment of 5G Core Network on Satellite显示文摘Recent developments in the aerospace industry have led to a dramatic reduction in the manufacturing and launch costs of low Earth orbit satellites.The new trend enables the paradigm shift of satelliteterrestrial integrated networks with global coverage.In particular,the integration of 5G communication systems and satellites has the potential to restructure nextgeneration mobile networks.By leveraging the network function virtualization and network slicing,the satellite 5G core networks will facilitate the coordination and management of network functions in satellite-terrestrial integrated networks.We are the first to deploy a 5G core network on a real-world satellite to investigate its feasibility.We conducted experiments to validate the satellite 5G core network functions.The validated procedures include registration and session setup procedures.The results show that the satellite 5G core network can function normally and generate correct signaling. | Ruolin Xing Xiao Ma Ao Zhou Schahram Dustdar Shangguang Wang | 2023 | China Communications2023，20，4： | 1 |
| 5 | The impact of water quality on the formation of halogenated benzoquinones and the adsorption efficiency by activated carbon显示文摘Halogenated benzoquinones(HBQs)could cause bladder cancer,but there were few related studies on the generation and control.In this study,the impact of different precursors,pH,bromide concentration,and algae-derived organic matters on the formation of HBQs and the removal efficiency by activated carbon were investigated.It was found that the chlorination of bisphenol A produced the most 2,6-dichloro-1,4-benzoquinone(2,6-DCBQ),reaching 14.86μg/L at 1 hr,followed by tyrosine,2-chlorophenol,P-hydroxybenzoic acid,trichlorophenol,and N-methylaniline.The production of 2,6-DCBQ increased first and then decreased from 0 to 36 hr(chlorination doses 0-20 mg/L),indicating that HBQs were unstable in water.Trihalomethanes(THMs)were detected during chlorination,and the concentration increased with prolongation of reaction time.2,6-DCBQ production decreased and 2,6-dibromo-1,4-benzoquinone(2,6-DBBQ)production increased with increment bromide concentration and the bromide promoted the formation of tribromomethane.The production of 2,6-DCBQ decreased with increase of pH,and the maximum production was 141.38μg/L at pH of 5.Microcystis aeruginosa,Chlorella algae cells,and intracellular organic matters(IOM)could be chlorinated as potential precursors for HBQs.The most amount of 2,6-DCBQ was generated from algae cells of Microcystis aeruginosa,followed by Chlorella algae cells,Microcystis aeruginosa IOM,and Chlorella IOM.This study compared the removal efficiency of HBQs by granular activated carbon(GAC)and columnar activated carbon(CAC)under different carbon doses and initial concentrations of HBQs.It was found that the removal efficiency by GAC(80.1%)was higher than that by CAC(51.8%),indicating that GAC has better control for HBQs. | Yongjing Wang Song Gao Xinyu Yan Songtao Wang Ruolin Zhang Yan Zhou Lianhai Ren Cheng Li | 2024 | Journal of Environmental Sciences2024，，1： | 0 |
| 6 | Occurrence and Health Risk of Perfluoroalkyl Acids in Popular Shellfish from a Typical Coastal Area of the East China显示文摘As crucial homologous members of per-and polyfluoroalkyl substances(PFASs),perfluoroalkyl acids(PFAAs)have aroused wide public concern because of their unique properties(persistence,bioaccumulation,long-distance migration and toxicity).Studies have shown their potential hazard to wildlife and humans,with food consumption as one of the primary routes of PFAA exposure for general population,especially seafood intake.In this study,17 PFAAs were quantified in 9 shellfish species from Yuhuan City,a typical coastal area of the East China.The total mean concentrations of PFAAs were in the range of 5.03–381 ng/g dry weight(dw),with the highest concentration found in Neverita didyma and the lowest in Babylonia lutosa.Concentrations and composition profiles of PFAAs varied significantly among different species,indicating differences in the bioaccumulation potential of PFAAs among species.Perfluorooctanoic acid(PFOA)was presented as the most abundant PFAA in this study,followed by perfluorobutanoic acid(PFBA).Significant positive correlations were observed among some individual PFAAs(p<0.05),indicating that they may share similar pollution sources or undergo similar compound behaviors.Health risk assessment indicated a relatively high threat for local residents exposed to PFAAs through shellfish consumption. | LIU Ruolin LIU Mei ZHAO Chuxuan FU Jianjie ZHOU Wei ZHANG Qinghua Martin HANSEN DONG Yin | 2023 | Chemical Research in Chinese Universities2023，39，3： | 0 |
