| 1 | Lane departure warning systems and lane line detection methods based on image processing and semantic segmentation:A review显示文摘Recently,the development and application of lane line departure warning systems have been in the market.For any of the systems,the key part of lane line tracking,lane line identification,or lane line departure warning is whether it can accurately and quickly detect lane lines.Since 1990 s,they have been studied and implemented for the situations defined by the good viewing conditions and the clear lane markings on road.After then,the accuracy for particular situations,the robustness for a wide range of scenarios,time efficiency and integration into higher-order tasks define visual lane line detection and tracking as a continuing research subject.At present,these kinds of lane marking line detection methods based on machine vision and image processing can be divided into two categories:the traditional image processing and semantic segmentation(includes deep learning)methods.The former mainly involves feature-based and model-based steps,and which can be classified into similarity-and discontinuity-based ones;and the model-based step includes different parametric straight line,curve or pattern models.The semantic segmentation includes different machine learning,neural network and deep learning methods,which is the new trend for the research and application of lane line departure warning systems.This paper describes and analyzes the lane line departure warning systems,image processing algorithms and semantic segmentation methods for lane line detection. | Weiwei Chen Weixing Wang Kevin Wang Zhaoying Li Huan Li Sheng Liu | 2020 | Journal of Traffic and Transportation Engineering(English Edition)2020，7，6： | 14 |
| 2 | Assessing the Dynamics of Grassland Net Primary Productivity in Response to Climate Change at the Global Scale显示文摘Understanding the net primary productivity(NPP) of grassland is crucial to evaluate the terrestrial carbon cycle. In this study, we investigated the spatial distribution and the area of global grassland across the globe. Then, we used the Carnegie-Ames-Stanford Approach(CASA) model to estimate global grassland NPP and explore the spatio-temporal variations of grassland NPP in response to climate change from 1982 to 2008. Results showed that the largest area of grassland distribution during the study period was in Asia(1737.23 × 104 km^2), while the grassland area in Europe was relatively small(202.83 × 10~4 km^2). Temporally, the total NPP increased with fluctuations from 1982 to 2008, with an annual increase rate of 0.03 Pg C/yr. The total NPP experienced a significant increasing trend from 1982 to 1995, while a decreasing trend was observed from 1996 to 2008. Spatially, the grassland NPP in South America and Africa were higher than the other regions, largely as a result of these regions are under warm and wet climatic conditions. The highest mean NPP was recorded for savannas(560.10 g C/(m^2·yr)), whereas the lowest was observed in open shrublands with an average NPP of 162.53 g C/(m^2·yr). The relationship between grassland NPP and annual mean temperature and annual precipitation(AMT, AP, respectively) varies with changes in AP, which indicates that, grassland NPP is more sensitive to precipitation than temperature. | LIU Yangyang YANG Yue WANG Qian KHALIFA Muhammad ZHANG Zhaoying TONG Linjing LI Jianlong SHI Aiping | 2019 | Chinese Geographical Science2019，29，5： | 12 |
| 3 | Footprint Problem with Angle of Attack Optimization for High Lifting Reentry Vehicle显示文摘A formal analysis to footprint problem with effects of angle of attack (AOA) is presented. First a flexible and rapid standardized method for footprint generation is developed. Zero bank angle control strategy and the maximum crossrange method are used to obtain virtual target set; afterward, closed-loop bank angle guidance law is used to find footprint by solving closest approach problem for each element in virtual target set. Then based on quasi-equilibrium glide condition, the typical inequality reentry trajectory constraints are converted to angle of attack lower boundary constraint. Constrained by the lower boundary, an original and practical angle of attack parametric method is proposed. By using parametric angle of attack profile, optimization algorithm for angle of attack is designed and the impact of angle of attack to footprint is discussed. Simulations with different angle of attack profiles are presented to demonstrate the performance of the proposed footprint solution method and validity of optimal algorithm. | LI Huifeng ZHANG Ran LI Zhaoying ZHANG Rui | 2012 | Chinese Journal of Aeronautics2012，25，2： | 8 |
| 4 | Initiation and Development of the Late Cenozoic Uplift of Daluo Mountains,Northeastern Margin of the Tibetan Plateau显示文摘Daluo Mountains lie at front of the arcuate tectonic belt at the northeastern margin of the Tibetan Plateau,and are the landform boundary zone between the active Tibetan Plateau and the stable North China Craton.Studying of the late Cenozoic uplift evolution of Daluo Mountains is important for understanding the expansion mechanism of the northeastern margin of the Tibetan Plateau and its influence on the western North China Craton.In this study,the late Cenozoic uplift of Daluo Mountains is constructed from the development of the late Cenozoic alluvial fan around Daluo Mountains.The entire sedimentary sequence and framework of the fan was revealed by the newly obtained drilling core data.The cosmogenic nuclide,optically stimulated luminescence,and detrital zircon U-Pb dating results provide new evidences for discussion about the initial timing of the late Cenozoic uplift of Daluo Mountains and the key stages of uplift during the Pleistocene.The late Cenozoic alluvial fan at front of Daluo Mountains overlies a set of fluvial-facies strata;therefore,development of the alluvial-fan marks the start of late Cenozoic uplift of Daluo Mountains.The timing of this event can be constrained to~4.64 Ma.Two extensive gravel layers(dated to ca.0.76–0.6 Ma and~0.05 Ma)developed during the Pleistocene,indicating two episodes of considerable uplift.This study provides a new time scale for the uplift and expansion of the arcuate tectonic belt at the northeastern margin of the Tibetan Plateau. | KOU Linlin DONG Xiaopeng LI Zhenhong CUI Jiawei MA Zhaoying LI Hailong | 2022 | Acta Geologica Sinica(English Edition)2022，96，6： | 2 |
| 5 | Comparative study on pyrolysis of bamboo in microwave pyrolysis-reforming reaction by binary compound impregnation and chemical liquid deposition modified HZSM-5显示文摘The deactivation of catalyst is a significant reason for its limited application during the catalytic fast pyrolysis(CFP)process.To reduce the coke formation,binary compound impregnation(BCI)and chemical liquid deposition(CLD)were used to modify HZSM-5 catalysts.At the same time,the self-designed microwave reactor separated the pyrolysis of bamboo and catalytic upgrading of primary vapor,which made the catalytic effect more thorough.Experimental results indicated that CLD used TiO 2 deposition to cover external acid sites,while BCI by phosphorus-nickel could cover and partly destroy superficial acid sites through two different ways.Within the scope of the loaded amount studied,the yield of aromatic hydrocarbons in the oil phase increased at first and then decreased,while the coke formation reduced continuously.BTX(benzene,toluene and xylene),the most valuable product in bio-oil,drastically increased by 39.1%and 22.6%respectively over the CLD and BCI modified catalysts.Considering the catalytic performance as well as cost,CLD over HZSM-5 has more advantages in the CFP process to upgrade bio-oil. | Haoran Du Zhaoping Zhong Bo Zhang Kun Shi Zhaoying Li | 2020 | Journal of Environmental Sciences2020，32，8： | 2 |
