| 1 | Energy-efficient adaptive sensor scheduling for target tracking in wireless sensor networks显示文摘Sensor scheduling is essential to collaborative target tracking in wireless sensor networks(WSNs).In the existing works for target tracking in WSNs,such as the information-driven sensor query(IDSQ),the tasking sensors are scheduled to maximize the information gain while minimizing the resource cost based on the uniform sampling intervals,ignoring the changing of the target dynamics and the specific desirable tracking goals.This paper proposes a novel energyefficient adaptive sensor scheduling approach that jointly selects tasking sensors and determines their associated sampling intervals according to the predicted tracking accuracy and tracking energy cost.At each time step,the sensors are scheduled in alternative tracking mode,namely,the fast tracking mode with smallest sampling interval or the tracking maintenance mode with larger sampling interval,according to a specified tracking error threshold.The approach employs an extended Kalman filter(EKF)-based estimation technique to predict the tracking accuracy and adopts an energy consumption model to predict the energy cost.Simulation results demonstrate that,compared to a non-adaptive sensor scheduling approach,the proposed approach can save energy cost significantly without degrading the tracking accuracy. | Wendong XIAO Sen ZHANG Jianyong LIN Chen Khong THAM | 2010 | 控制理论与应用(英文版)2010，8，1： | 9 |
| 2 | A new self-learning optimal control laws for a class of discrete-time nonlinear systems based on ESN architecture显示文摘A novel self-learning optimal control method for a class of discrete-time nonlinear systems is proposed based on iteration adaptive dynamic programming(ADP)algorithm.It is proven that the iteration costate functions converge to the optimal one,and a detailed convergence analysis of the iteration ADP algorithm is given.Furthermore,echo state network(ESN)architecture is used as the approximator of the costate function for each iteration.To ensure the reliability of the ESN approximator,the ESN mean square training error is constrained in the satisfactory range.Two simulation examples are given to demonstrate that the proposed control method has a fast response speed due to the special structure and the fast training process. | SONG RuiZhuo XIAO WenDong SUN ChangYin | 2014 | Science China(Information Sciences)2014，57，6： | 4 |
| 3 | Optimal full-order filtering for discrete-time systems with random measurement delays and multiple packet dropouts显示文摘This paper is concerned with the estimation problem for discrete-time stochastic linear systems with possible single unit delay and multiple packet dropouts.Based on a proposed uncertain model in data transmission,an optimal full-order filter for the state of the system is presented,which is shown to be of the form of employing the received outputs at the current and last time instants.The solution to the optimal filter is given in terms of a Riccati difference equation governed by two binary random variables.The optimal filter is reduced to the standard Kalman filter when there are no random delays and packet dropouts.The steady-state filter is also investigated.A sufficient condition for the existence of the steady-state filter is given.The asymptotic stability of the optimal filter is analyzed. | Shuli SUN Lihua XIE Wendong XIAO | 2010 | 控制理论与应用(英文版)2010，8，1： | 4 |
| 4 | Investigation of Coal Fueled Chemical Looping Combustion Using Fe_3O_4 as Oxygen Carrier:Influence of Variables显示文摘Chemical-looping combustion (CLC) is a novel combustion technique with inherent CO2 separation.Magnetite (Fe3O4) was selected as the oxygen carrier.Shenhua coal (Inner Mongolia,China),straw coke and natural coke were used as fuels for this study.Influences of operation temperatures,coal to Fe3O4 mass ratios,and different kinds of fuels on the reduction characteristics of the oxygen carrier were investigated using an atmosphere thermogravimetric analyzer (TGA).Scanning electron microscopy (SEM) was used to analyse the characteristic of the solid residues.Experimental results shown that the reaction between the coal and the oxygen carrier become strong at a temperature of higher than 800℃.As the operation temperature rises,the reduction conversion rate increases.At the temperatures of 850oС,900℃,and 950℃,the reduction conversion rates were 37.1%,46.5%,and 54.1% respectively.However,SEM images show that at the temperature of higher than 950℃,the iron oxides become melted and sintered.The possible operation temperature should be kept around 900℃.When the mass ratios of coal to Fe3O4 were 5/95,10/90,15/85,and 20/80,the reduction conversion rates were 29.5%,40.8%,46.5%,and 46.6% respectively.With the increase of coal,the conversion rate goes up.But there exist an optimal ratio around 15/85.Comparisons based on different kinds of fuels show that the solid fuel with a higher volatile and a more developed pore structure is conducive to the reduction reactivity of the oxygen carrier. | Xiaoyan Sun Wenguo Xiang Sha Wang Wendong Tian Xiang Xu Yanji Xu Yunhan Xiao | 2010 | Journal of Thermal Science2010，19，3： | 3 |
| 5 | Energy and Exergy Analysis of a Novel Efficient Combined Process by Hydrothermal Degradation and Superheated Steam Drying of Degradable Organic Wastes显示文摘This paper considers the combination of hydrothermal degradation(HTD)and superheated steam(SHS)drying indisposal and processing of degradable organic wastes in municipal solid wastes(MSW).In SHS drying, a fractionof dryer thermal energy input can be recovered and used to satisfy the heat requirement in maintaining the HTDoperating temperature.Both energy and exergy analysis are applied to the combined process.The analysis coversranges of dryer inlet temperatures of 202.38-234.19℃ and feed water content of 32.5-65%.Thermal energyanalysis shows that the combination of HTD and SHS drying can achieve thermal energy self-sufficiency(TES)by manipulating process variables.The exergy analysis indicates the location,type,and magnitude of the exergylosses during the whole process by applying the second law of thermodynamics. | Shuqing GUO Yunhan XIAO Wendong TIAN Zhedian ZHANG | 2006 | Journal of Thermal Science2006，15，3： | 2 |

| 9 | Passivation of Ge surface treated with trimethylaluminum and investigation of electrical properties of HfTiO/Ge gate stacks显示文摘In the current work, in situ surface passivation Ge substrate by using trimethylaluminum(TMA) prior to HfTiO films deposition and electrical properties of HfTiO/Ge gate stacks have been investigated by X-ray photoelectron spectroscopy(XPS) and electrical measurements systematically. Based on analysis from XPS measurements, it has been confirmed that the interfacial layer of HfTiO/Ge gate stack has been suppressed effectively after 20 half-ALD cycles TMA pretreatment. Electrical properties of metal-oxidesemiconductor(MOS) capacitor based on HfTiO gate dielectrics have shown that the MOS capacitor with20 cycles TMA cleaning exhibits the lowest interface state density(~7.56 eV^(-1)cm^(-2)) and the smallest leakage current(~2.67 × 10^(-5)A/cm^2). Correspondingly, the leakage current conduction mechanisms for MOS capacitor device with 20 cycles TMA cleaning also have been discussed in detail. | Juan Gao Gang He Dongqi Xiao Peng Jin Shanshan Jiang Wendong Li Shuang Liang Li Zhu | 2017 | Journal of Materials Science & Technology2017，33，8： | 1 |

| 16 | Facile Preparation of a Porous Biochar Derived from Waste Crab Shell with High Removal Performance for Diesel显示文摘In this study,a porous biochar material derived from waste crab shell was prepared by one-step hydrothermal carbonization and acetic acid activation method at 180°C,which was characterized by SEM,BET,XRD and FTIR.The results show that the as-prepared crab shell biochar(CSB)exhibits a fluffy irregular layered structure with abundant pores and oxygen-containing functional groups,which can facilitate the adsorption of diesel using CSB.In addition,batch adsorption experiments had been performed,effects of initial diesel concentration,adsorption time,adsorbent dosage and pH on the diesel adsorption using CSB were analyzed,which could be observed that CSB has high removal efficiency for diesel,and the maximum removal rate is up to 80.1%.The adsorption isotherms and kinetic studies were also investigated to determine the adsorption mechanism of diesel using CSB,the results show that the Langmuir model and the pseudo-second-order model are more suitable for describing the adsorption of diesel using CSB,indicating that the adsorption of diesel oil by CSB is monolayer chemical adsorption.This study will provide a theoretical basis for the high-value utilization of waste crab shell,which has a great potential in the treatment of oil spill. | Xiao Han Zhaodi Wu Yi Yang Jian Guo Yaning Wang Lu Cai Wendong Song Lili Ji | 2021 | Journal of Renewable Materials2021，9，8： | 1 |
