| 1 | Energy-Theft Detection Issues for Advanced Metering Infrastructure in Smart Grid显示文摘With the proliferation of smart grid research,the Advanced Metering Infrastructure(AMI) has become the first ubiquitous and fixed computing platform. However,due to the unique characteristics of AMI,such as complex network structure,resource-constrained smart meter,and privacy-sensitive data,it is an especially challenging issue to make AMI secure. Energy theft is one of the most important concerns related to the smart grid implementation. It is estimated that utility companies lose more than $25 billion every year due to energy theft around the world. To address this challenge,in this paper,we discuss the background of AMI and identify major security requirements that AMI should meet. Specifically,an attack tree based threat model is first presented to illustrate the energy-theft behaviors in AMI. Then,we summarize the current AMI energy-theft detection schemes into three categories,i.e.,classification-based,state estimation-based,and game theory-based ones,and make extensive comparisons and discussions on them. In order to provide a deep understanding of security vulnerabilities and solutions in AMI and shed light on future research directions,we also explore some open challenges and potential solutions for energy-theft detection. | Rong Jiang Rongxing Lu Ye Wang Jun Luo Changxiang Shen Xuemin(Sherman) Shen | 2014 | Tsinghua Science and Technology2014，19，2： | 22 |
| 2 | Current issues in high-resolution earth observation technology显示文摘This paper reviewed the developments of the last ten years in the field of international high-resolution earth observation, and introduced the developmental status and plans for China's high-resolution earth observation program. In addition, this paper expounded the transformation mechanism and procedure from earth observation data to geospatial information and geographical knowledge, and examined the key scientific and technological issues, including earth observation networks, high-precision image positioning, image understanding, automatic spatial information extraction, and focus services. These analyses provide a new impetus for pushing the application of China's high-resolution earth observation system from a 'quantity' to 'quality' change, from China to the world, from providing products to providing online service. | LI DeRen TONG QingXi LI RongXing GONG JianYa ZHANG LiangPei | 2012 | Science China Earth Sciences2012，55，7： | 18 |
| 3 | Designing efficient proxy signature schemes for mobile communication显示文摘Proxy signature is an active cryptographic research area,and a wide range of litera- tures can be found nowadays suggesting improvement and generalization of existing protocols in various directions.However,from the efficiency view,many proposed proxy signature schemes in these literatures are not satisfying and cannot fit to the mobile communication.Therefore,there is a desire to design efficient proxy sig- nature schemes.Based on Boneh et al's pairing-based short signature,this paper presents two proxy signature schemes.One is proxy-protected signature scheme, and the other is proxy aggregate signature scheme.Since both of them can achieve high efficiency,it is believed that they are specially suitable for mobile communica- tion environment. | LU RongXing DONG XiaoLei CAO ZhenFu | 2008 | Science in China(Series F)2008，51，2： | 9 |
| 4 | Acoustic radiation field of the truncated parametric source generated by a piston radiator:model and experiment显示文摘A theoretical model is presented to describe the parametric acoustic field generated by a piston radiator. In the model, the high-frequency primary wave interaction region that is truncated by a low-pass acoustic filter can be viewed as a cylindrical source within the Rayleigh distance of the piston. When the radius of the piston is much smaller than the length of the parametric region, this model is reduced to the Berketey’s End-Fire Line Army model. Comparison between numerical calculations and experimental measurement show that the generated parametric sound field (especially near the axis) agrees well with the experiment results. | ZHAO Xiaoliang,ZHU Zhemin,DU Gonghuan (Institute of Acoustics and State Key Laboratory of Modern Acoustics, Nanjing University Nanjing 210093) TANG Haiqing,LI Shui,MIAO Rongxing (Hangzhou Applied Acoustics Institute Fuyang, Hangzhou 311400) | 2001 | Chinese Journal of Acoustics2001，20，1： | 8 |
| 5 | Sizing optimization for island microgrid with pumped storage system considering demand response显示文摘Currently, small islands are facing an energy supply shortage, which has led to considerable concern.Establishing an island microgrid is a relatively good solution to the problem. However, high investment costs restrict its application. In this paper, micro pumped storage(MPS) is used as an energy storage system(ESS) for islands with good geographical conditions, and deferrable appliance is treated as the virtual power source which can be used in the planning and operational processes.Household acceptance of demand response(DR) is indicated by the demand response participation degree(DRPD), and a sizing optimization model for considering the demand response of household appliances in an island microgrid is proposed. The particle swarm optimization(PSO) is used to obtain the optimal sizing of all major devices. In addition, the battery storage(BS) scheme is used as the control group. The results of case studies demonstrate that the proposed method is effective, and the DR of deferrable appliances and the application of MPS can significantly reduce island microgrid investment.Sensitivity analysis on the total load of the island and the water head of the MPS are conducted. | Zhaoxia JING Jisong ZHU Rongxing HU | 2018 | Journal of Modern Power Systems and Clean Energy2018，6，4： | 6 |
| 6 | Provably secure robust threshold partial blind signature显示文摘Threshold digital signature and blind signature are playing important roles in cryptography as well as in practical applications such as e-cash and e-voting systems. Over the past few years, many cryptographic researchers have made considerable headway in this field. However, to our knowledge, most of existing threshold blind signature schemes are based on the discrete logarithm problem. In this paper, we propose a new robust threshold partial blind signature scheme based on improved RSA cryptosystem. This scheme is the first threshold partial blind signature scheme based on factoring, and the robustness of threshold partial blind signature is also introduced. Moreover, in practical application, the proposed scheme will be especially suitable for blind signature-based voting systems with multiple administrators and secure electronic cash systems to prevent their abuse. | CAO Zhenfu ZHU Haojin LU Rongxing | 2006 | Science in China(Series F)2006，49，5： | 5 |
| 7 | Formamidinium Lead Bromide (FAPbBr_3) Perovskite Microcrystals for Sensitive and Fast Photodetectors显示文摘Because of the good thermal stability and superior carrier transport characteristics of formamidinium lead trihalide perovskite HC(NH_2)_2 PbX_3(FAPbX_3), it has been considered to be a better optoelectronic material than conventional CH_3NH_3-PbX_3(MAPbX_3). Herein, we fabricated a FAPbBr_3 microcrystal-based photodetector that exhibited a good responsivity of 4000 A W-1 and external quantum efficiency up to 106% under one-photon excitation, corresponding to the detectivity greater than 1014 Jones. The responsivity is two orders of magnitude higher than that of previously reported formamidinium perovskite photodetectors. Furthermore, the FAPbBr_3 photodetector's responsivity to two-photon absorption with an 800-nm excitation source can reach 0.07 A W^(-1), which is four orders of magnitude higher than that of its MAPbBr_3 counterparts. The response time of this photodetector is less than 1 ms.This study provides solid evidence that FAPbBr_3 can be an excellent candidate for highly sensitive and fast photodetectors. | Fengying Zhang Bin Yang Kaibo Zheng Songqiu Yang Yajuan Li Weiqiao Deng Rongxing He | 2018 | Nano-Micro Letters2018，10，3： | 2 |
| 8 | Deformation and recrystallization behavior of a Fe-20Mn-3Si-3Al-0.045C steel under cold-rolling显示文摘The influence of cold rolling reduction on microstructure and mechanical properties of the twinning induced plasticity(TWIP) steel with a chemical composition of Fe-20Mn-3Si-3Al-0.045 C has been investigated.Tensile tests were carried out to explore the mechanical properties of TWIP steel with different cold rolling reductions.The microstructures were observed by optical microscopy and transmission electron microscopy(TEM).The misorientation and the development of recrystallization texture in TWIP steel sheets were investigated by Electron Back Scatter Diffraction(EBSD) technique.The results indicated that the steel exhibited attractively mechanical properties when cold rolling reduction was about 10%.The tensile strength of the steel with a rolling reduction of 10%is higher than 900 MPa and the yield strength is about 800 MPa,while the elongation is above 35%.The microstructure is composed of austenitic matrix and deformation twins at room temperature,at the same time,a significant amount of deformation twins,stacking faults and dislocations are observed by TEM.TEM observations showed the presence of deformation twinning in the sample at low rolling reduction.As the strain increases the volume fraction of twins increases.Mechanical twins play a dominant role during deformation and result in excellent mechanical properties for the investigated steel.By TEM observation,the possible deformation mechanisms can be suggested as:with the increasing strain,formation of the twin will gradually play a more important role during deformation.The interaction between twins and dislocations enhances the strain hardening rate in the sample.Consequently,the necking is delayed and a good ductility is obtained.Twins were always observed in the region with high density of dislocation and faults,suggesting that the interaction among blocked dislocations and faults as well as deformation twins promote the increase in material strength.EBSD observation showed that the textures has evolved according to the following trend:the brass orientation {110}〈112〉and Goss orientation {110}〈001〉are dominant at every strain level,those intensities increase with increasing strain,while with the increase of the strain level,the change of S orientation {123}〈634〉was not obviously. | SHEN Yongfeng~(1)),HUANG Shaoshuai~(1)),ZHANG Rongxing~(1)),XUE Wenying~(2)) and HE Tong~(3)) 1) Key Laboratory for Anisotropy and Texture of Materials(Ministry of Education), Northeastern University,Shenyang 110004,Liaoning,China 2) The State Key Lab of Rolling & Automation,Northeastern University,Shenyang 110004, Liaoning,China 3) Institute of Research,Northeastern University,Shenyang 110004,Liaoning,China | 2010 | Baosteel Technical Research2010，4，S1： | 2 |
| 9 | SIMULATING REGIONAL SYSTEMS: A SYSTEM DYNAMICS APPROACH显示文摘System dynamics is a rigorous method for qualitative description,exploration and analysis of complex systems in terms of their processes, information flows, orgaruzational boundaries and strategies, which facilitates quantitative modelling and analysis for design of system structure and the improvement of system behaviour. It can be applied to the study of a wide range of systems, and its ability to describe socio-economic characteristics and behaviour makes it suitable for the analysis of the regional development process. Three examples of System Dynamics models are reviewd to demonstrate the suitability of the method for regional analysis, and on the basis of this review the potential use of system dynamics models in China is discussed. | Colllin Lee(School of the Built Environment, Coventry University, Coventry, U.K.)Guo Rongxing (Beijing Graduate School of CUMT, and Paking University, Beijing 100871 People’s Republic of China ) | 1996 | Journal of Geographical Sciences1996，6，2： | 2 |
| 10 | UMBRELLA: user demand privacy preserving framework based on association rules and differential privacy in social networks显示文摘Dear editor,The past several years have witnessed that people deeply rely on online services,such as shopping,transportation,and medical services.At the same time,privacy leakage has been a hot topic in social networks[1,2].Morever,the increasing applications of location based services(LBSs)indeed make our lives more convenient.However,LBSs also lead to significant privacy leakage.On the one hand,location information of a single point is sensitive.On the other hand,location trajec.tories can excavate more sensitive information despite location.In this regard,location privacy-preserving mechanisms have been extensively studied,such as Dunmiy,spatial confusion[3,4],encryption technology[5,6],differential privacy(DP)[7,8]and references therein. | Chunliu YAN Ziyi NI Bin CAO Rongxing LU Shaohua WU Qinyu ZHANG | 2019 | Science China(Information Sciences)2019，62，3： | 2 |
| 11 | A novel ball-in-ball hollow oxygen-incorporating cobalt sulfide spheres as high-efficient electrocatalyst for oxygen evolution reaction显示文摘Transition-metal chalcogenides with hollow nanostructure,especially cobalt sulfides,are considered as the most pro mising non-precious metal catalysts for oxygen evolution reactio n.However,it is difficult to synthesize oxygen-containing cobalt sulphides with hollow structure due to the different physical/chemical properties between metal sulfides and metal cobalts.Herein,we report a novel oxygencontaining amorphous cobalt sulfide ball-in-ball hollow sphere s(Co-S-O BBHS) synthesized by an anion exchange method.Taking advantage of the ball-in-ball hollow structure,the amorphous Co-S-O BBHS shows supe rior oxygen evolution reaction(OER) electrocatalytic performance with a low overpotentiat of285 mV at 10 mA/cm2,small Tafel slope of 49.67 mV/dec,high Faraday efficiency of 96%,and satisfied durability.Experiments and DFT calculations demonstrate that the introduction of oxygen and sulfur modulates the electronic structure of Co-S-O BBHS,thus enhancing the adsorption of *0(adsorbed 0 species on catalyst surface) intermediate,which greatly boosts the catalytic activity towards OER.This work provides a new strategy for controllable synthe sis of complex hollow structures of transition-metal chalcogenides for OER. | Yurong Li Qifei Guo Yimin Jiang Wei Shen Ming Li Rongxing He | 2021 | Chinese Chemical Letters2021，32，2： | 2 |
| 12 | MOF-Transformed In_(2)O_(3-x)@C Nanocorn Electrocatalyst for Efficient CO_(2)Reduction to HCOOH显示文摘For electrochemical CO_(2) reduction to HCOOH,an ongoing challenge is to design energy efficient electrocatalysts that can deliver a high HCOOH current density(JHCOOH)at a low overpotential.Indium oxide is good HCOOH production catalyst but with low con-ductivity.In this work,we report a unique corn design of In_(2)O_(3-x)@C nanocatalyst,wherein In_(2)O_(3-x)nanocube as the fine grains dispersed uniformly on the carbon nanorod cob,resulting in the enhanced conductivity.Excellent performance is achieved with 84%Faradaic efficiency(FE)and 11 mA cm^(−2)JHCOOH at a low potential of−0.4 V versus RHE.At the current density of 100 mA cm^(−2),the applied potential remained stable for more than 120 h with the FE above 90%.Density functional theory calculations reveal that the abundant oxygen vacancy in In_(2)O_(3-x) has exposed more In^(3+) sites with activated electroactivity,which facilitates the formation of HCOO*intermediate.Operando X-ray absorp-tion spectroscopy also confirms In^(3+) as the active site and the key intermediate of HCOO*during the process of CO_(2) reduction to HCOOH. | Chen Qiu Kun Qian Jun Yu Mingzi Sun Shoufu Cao Jinqiang Gao Rongxing Yu Lingzhe Fang Youwei Yao Xiaoqing Lu Tao Li Bolong Huang Shihe Yang | 2022 | Nano-Micro Letters2022，14，10： | 2 |
| 13 | Thickness-Shear Frequencies of an Infinite Quartz Plate with Graded Material Properties Across the Thickness显示文摘For quartz crystal resonators of thickness-shear type,the vibration frequency and mode shapes reflect the basic material and structural properties of a quartz crystal plate and the variation with time under attack by erosive gases and liquids that can cause surface and internal degradation in a graded form.Such gradual effects,in turn,will change surface conditions through elastic constants and stiffness and more importantly the gradient of such properties across the thickness with certain depth.Now we study the thickness-shear vibrations of functionally graded material plates with properties of the popular AT-cut quartz crystal varying across the thickness in a general pattern represented by both sine and cosine components of the thickness.The vibration solutions are obtained through the Fourier expansion of the plate deformation. | Rongxing Wu Wenliang Zhang Tingfeng Ma Jianke Du Ji Wang | 2020 | Acta Mechanica Solida Sinica2020，33，3： | 2 |
| 14 | Method based on broadband compressed pulse superposition to measure properties of underwater acoustic materials显示文摘A method is proposed for the measurements of the performances of underwater acoustic finite sized large area material samples in a free field by using broadband pulse compression technique. As the result of which, the low-frequency cutoff of the standard tests is obviously reduced, and the broadband measurements are also realized. The experimental system provides measurements of complex reflection and transmission coefficients at continuous frequency points. From the data one can obtain the following acoustic parameters: echo reduction and insertion loss, absorption and attenuation coefficients, etc. The measurements are performed for two actual panels with the size 1 m x 1 m in the frequency range from 2-20 kHz. | LI Shui,MIAO Rongxing (National Defence Underwater Acoustic Metrology Center Fuyang Zhejiang 311400) | 2001 | Chinese Journal of Acoustics2001，20，1： | 2 |
