| 3 | An Examination of the Predictability of Tropical Cyclone Genesis in High-Resolution Coupled Models with Dynamically Downscaled Coupled Data Assimilation Initialization显示文摘Predicting tropical cyclone(TC)genesis is of great societal importance but scientifically challenging.It requires fineresolution coupled models that properly represent air−sea interactions in the atmospheric responses to local warm sea surface temperatures and feedbacks,with aid from coherent coupled initialization.This study uses three sets of highresolution regional coupled models(RCMs)covering the Asia−Pacific(AP)region initialized with local observations and dynamically downscaled coupled data assimilation to evaluate the predictability of TC genesis in the West Pacific.The APRCMs consist of three sets of high-resolution configurations of the Weather Research and Forecasting−Regional Ocean Model System(WRF-ROMS):27-km WRF with 9-km ROMS,and 9-km WRF with 3-km ROMS.In this study,a 9-km WRF with 9-km ROMS coupled model system is also used in a case test for the predictability of TC genesis.Since the local sea surface temperatures and wind shear conditions that favor TC formation are better resolved,the enhanced-resolution coupled model tends to improve the predictability of TC genesis,which could be further improved by improving planetary boundary layer physics,thus resolving better air−sea and air−land interactions. | Mingkui LI Shaoqing ZHANG Lixin WU Xiaopei LIN Ping CHANG Gohkan DANABASOGLU Zhiqiang WEI Xiaolin YU Huiqin HU Xiaohui MA Weiwei MA Haoran ZHAO Dongning JIA Xin LIU Kai MAO Youwei MA Yingjing JIANG Xue WANG Guangliang LIU Yuhu CHEN | 2020 | Advances in Atmospheric Sciences2020,37,9: | 4 |
| 4 | An Equivalent Substitute Strategy for Constructing 3D Ordered Porous Carbon Foams and Their Electromagnetic Attenuation Mechanism显示文摘Three-dimensional(3D)ordered porous carbon is generally believed to be a promising electromagnetic wave(EMW)absorbing material.However,most research works targeted performance improvement of 3D ordered porous carbon,and the specific attenuation mechanism is still ambiguous.Therefore,in this work,a novel ultra-light egg-derived porous carbon foam(EDCF)structure has been successfully constructed by a simple carbonization combined with the silica microsphere template-etching process.Based on an equivalent substitute strategy,the influence of pore volume and specific surface area on the electromagnetic parameters and EMW absorption properties of the EDCF products was confirmed respectively by adjusting the addition content and diameter of silica microspheres.As a primary attenuation mode,the dielectric loss originates from the comprehensive effect of conduction loss and polarization loss in S-band and C band,and the value is dominated by polarization loss in X band and Ku band,which is obviously greater than that of conduction loss.Furthermore,in all samples,the largest effective absorption bandwidth of EDCF-3 is 7.12 GHz under the thickness of 2.13 mm with the filling content of approximately 5 wt%,covering the whole Ku band.Meanwhile,the EDCF-7 sample with optimized pore volume and specific surface area achieves minimum reflection loss(RL_(min))of−58.08 dB at 16.86 GHz while the thickness is 1.27 mm.The outstanding research results not only provide a novel insight into enhancement of EMW absorption properties but also clarify the dominant dissipation mechanism for the porous carbon-based absorber from the perspective of objective experiments. | Meng Zhang Hailong Ling Ting Wang Yingjing Jiang Guanying Song Wen Zhao Laibin Zhao Tingting Cheng Yuxin Xie Yuying Guo Wenxin Zhao Liying Yuan Alan Meng Zhenjiang Li | 2022 | Nano-Micro Letters2022,14,10: | 3 |
| 5 | Autonomous navigation to quasi-periodic orbits near translunar libration points显示文摘Libration-point missions have been very useful and successful.Due to the unstable natures of most of these orbits,the long-time stationkeeping demands frequent maneuvers and precise orbit determinations.Earth-based tracking will have to undertake much more responsibilities with the increasing number of libration missions.An autonomous navigation system could offer a better way to decrease the need for Earth-based tracking.Nevertheless,when an autonomous navigation system is applied,there are three important factors affecting autonomous navigation accuracy,i.e.,the accuracy of initial conditions,the accuracy of measurements,and the accuracy of onboard dynamics for propagation.This paper focuses on analyzing the influence from the third factor and fnding an appropriate navigation dynamics,which can satisfy the requirement of estimation accuracy but not cause too much burden for onboard computation.When considering the restricted three-body model and the bicircular restricted four-body model as navigation dynamics,the astringency is not shown during the simulations.Meanwhile,when considering the influences of the Sun's direct and indirect perturbations and the eccentricity of the Moon's orbit,a new navigation dynamic model with the standard ephemerides is proposed.The simulation shows the feasibility of the proposed model. | Jing Wuxing Qian Yingjing Gao Changsheng Li Jianqing | 2013 | Chinese Journal of Aeronautics2013,26,5: | 3 |
| 6 | Multiple hypothesis tracking based on the Shiryayev sequential probability ratio test显示文摘To date, Wald sequential probability ratio test(WSPRT) has been widely applied to track management of multiple hypothesis tracking(MHT). But in a real situation, if the false alarm spatial density is much larger than the new target spatial density, the original track score will be very close to the deletion threshold of the WSPRT. Consequently, all tracks, including target tracks, may easily be deleted, which means that the tracking performance is sensitive to the tracking environment. Meanwhile, if a target exists for a long time, its track will have a high score, which will make the track survive for a long time even after the target has disappeared. In this paper, to consider the relationship between the hypotheses of the test, we adopt the Shiryayev SPRT(SSPRT) for track management in MHT. By introducing a hypothesis transition probability, the original track score can increase faster, which solves the first problem. In addition, by setting an independent SSPRT for track deletion, the track score can decrease faster, which solves the second problem. The simulation results show that the proposed SSPRT-based MHT can achieve better tracking performance than MHT based on the WSPRT under a high false alarm spatial density. | Jinbin FU Jinping SUN Songtao LU Yingjing ZHANG | 2016 | Science China Earth Sciences2016,59,12: | 2 |
| 7 | Scheduling Rate-Constrained Flows with Dynamic Programming Priority in Time-Triggered Ethernet显示文摘Time-triggered(TT), Rate-constrained(RC) and Best-effort(BE) traffics are included in Timetriggered ethernet(TTEthernet). For RC messages transmission is affected by TT messages, traditional scheduling policy cannot be well applied in TTEthernet. Dynamic programming priority(DPP) algorithm combines priority policy and dynamic programming algorithm for scheduling RC flows. The time slice for RC flows transmission is got by SMT solver YICES; RC flows are classified to different groups according to the priorities; Higher priority packets in one time slice are scheduled using First input first output(FIFO) policy and lower priority packets are scheduled by Dynamic programming policy. DPP policy guarantees different real-time requirements of heterogeneous RC flows, and make the best of time slice resource in aviation industries. The upper bound End-End of three methods and algorithm feasibility is analyzed. Simulation in aviation shows that DPP policy can obtain better real-time performance than other scheduling algorithms. | ZHANG Yingjing HE Feng LU Guangshan XIONG Huagang | 2017 | Chinese Journal of Electronics2017,26,4: | 2 |
| 8 | Prediction of nonlocal scale parameter for carbon nanotubes显示文摘Based on the theory of nonlocal elasticity,a nonlocal shell model accounting for the small scale effect is developed for the bending characteristics of CNTs subjected to the concentrated load.With this nonlocal shell model,explicit expressions are derived for the bending solutions.To extract the proper values of nonlocal scale parameter,we have made molecular dynamics(MD) simulations for various radii and lengths of armchair and zigzag CNTs,the results of which are matched with those of nonlocal continuum model.It is found that the present nonlocal elastic shell model with its appropriate values of nonlocal scale parameter has the capability to predict the bending behavior of CNTs,which is comparable with the results of MD simulations.Moreover,exact closed form solutions for the nonlocal scale parameter for zigzag and armchair CNTs are obtained.The results show that nonlocal scale parameter is independent of the length of CNTs,and dependent on the radius of CNTs. | LIANG YingJing HAN Qiang | 2012 | Science China(Physics,Mechanics & Astronomy)2012,55,9: | 2 |

| 20 | An improved numerical method for constructing Halo/Lissajous orbits in a full solar system model显示文摘An improved numerical method that can construct Halo/Lissajous orbits in the vicinity of collinear libration points in a full solar system model is investigated. A full solar system gravitational model in the geocentric rotating coordinate system with a clear presentation of the angular velocity relative to the inertial coordinate system is proposed. An alternative way to determine patch points in the multiple shooting method is provided based on a dynamical analysis with Poincare′sections. By employing the new patch points and sequential quadratic programming, Halo orbits for L_1, L_2, and L_3 points as well as Lissajous orbits for L_1 and L_2 points in the EarthMoon system are generated with the proposed full solar system gravitational model to verify the effectiveness of the proposed method. | Yingjing QIAN Xiaodong YANG Wuxing JING Wei ZHANG | 2018 | Chinese Journal of Aeronautics2018,31,6: | 1 |
