2What about people in pedestrian navigation?显示文摘Pedestrian navigation has become an important theoretical and practical research topic in many disciplines such as cartography,geographical information science,global and indoor positioning,spatial behavior,psychology,sociology,and neuroscience.Many research studies view pedestrian navigation using process-oriented and goal-directed approaches.However,this paper revisits people’s needs in pedestrian navigation and classifies their needs as three layers:physical sense layer,physiological safety layer,and mental satisfaction layer according to Maslow’s theory.This paper introduces a people-centric framework for pedestrian navigation theory based on these three layers and discusses theoretical challenges for meeting each layer of people’s needs.These challenging theories may represent promising and valuable research and promote usage of pedestrian navigation systems or devices in the future.Zhixiang FANG Qingquan LI Shih-Lung SHAW 2015Geo-Spatial Information Science2015,18,4:4
3The heterogeneity of hydrometeorological changes during the period of 1961-2016 in the source region of the Yellow River, China显示文摘Runoff in the source region of a river makes up most of water resources in the whole basin in arid and semi-arid areas. It is very important for water resources management to timely master the latest dynamic changes of the runoff and quantitatively reveal its main driving factors. This paper aims to discover the variation heterogeneity of runoff and the impacts of climatic factors on this runoff in the source region of the Yellow River(SRYR) in China from 1961 to 2016. We divided SRYR into four sub-regions, and analyzed changes of their contributions to total runoff in SRYR. We also revealed the impacts of precipitation, temperature and potential evapotranspiration on runoff in each sub-region by constructing the regression relationships between them at multiple temporal scales. The changes of runoff in the four sub-regions and their contributions to the total runoff were not exactly consistent. The climatic variables’ changes also have heterogeneity, and runoff was mainly affected by precipitation compared to influences of temperature or potential evapotranspiration. Their impacts on runoff have spatiotemporal heterogeneity and can be reflected by very significant-linear regression equations.It provided a simple method to predict headwater runoff for better water management in the whole basin.ZhiXiang Lu Qi Feng SongBing Zou JiaLi Xie ZhenLiang Yin Fang Li 2020Research in Cold and Arid Regions2020,12,2:3
4Detecting visually salient scene areas and deriving their relative spatial relations from continuous street-view panoramas显示文摘A salient scene is an area within an image that contains visual elements that stand out from surrounding areas.They are important for distinguishing landmarks in first-person-view(FPV)applications and determining spatial relations in images.The relative spatial relation between salient scenes acts as a visual guide that is easily accepted and understood by users in FPV applications.However,current digitally navigable maps and location-based services fall short of providing information on visual spatial relations for users.This shortcoming has a critical influence on the popularity and innovation of FPV applications.This paper addresses the issue by proposing a method for detecting visually salient scene areas(SSAs)and deriving their relative spatial relationships from continuous panoramas.This method includes three critical steps.First,an SSA detection approach is introduced by fusing region-based saliency derived from super-pixel segmentation and the frequency-tuned saliency model.The method focuses on a segmented landmark area in a panorama.Secondly,a street-view-oriented SSA generation method is introduced by matching and merging the visual SSAs from continuous panoramas.Thirdly,a continuous geotagged panorama-based referencing approach is introduced to derive the relative spatial relationships of SSAs from continuous panoramas.This information includes the relative azimuth,elevation angle,and the relative distance.Experiment results show that the error for the SSA relative azimuth angle is approximately±6°(with an average error of 2.67°),and the SSA relative elevation angle is approximately±4°(with an average error of 1.32°)when using Baidu street-view panoramas.These results demonstrate the feasibility of the proposed approach.The method proposed in this study can facilitate the development of FPV applications such as augmented reality(AR)and pedestrian navigation using proper spatial relation.Fangli Guan Zhixiang Fang Tao Yu Mingxiang Feng Fan Yang 2020International Journal of Digital Earth2020,13,12:2

16Controlling the morphology, size and phase of Nb_2O_5 crystals for high electrochemical performance显示文摘The morphology, size and phase of the material play a crucial role in its electrochemical performance.Herein, the nano-sized niobium pentoxide(Nb_2O_5) with different morphologies and phase structures are synthesized through a very simple thermal treatment method, including the pseudo hexagonal Nb_2O_5 nanosheets and pseudo hexagonal Nb_2O_5 nanoparticles, orthorhombic Nb_2O_5 nanoparticles. The synthesized pseudohexagonal Nb2O5 nanosheets and orthorhombic Nb_2O_5 nanoparticles exhibit better cycling and rate performance than the pseudohexagonal Nb2 O5 nanoparticles due to the different morphologies and phase structures. The T-Nb_2O_5-700 nanoparticles show the higher capacity(175 mAh/g) than that of TT-Nb_2O_5-500 nanosheets(127 mAh/g) and TT-Nb_2O_5-600 nanoparticles(39 mAh/g) at a current density of 50 mA/g and good rate performance with a capacity of 140 mAh/g at 1.0 A/g. The excellent rate capability and cycling stability of orthorhombic T-Nb_2O_5 may be ascribed to the dominant contribution of pseudocapacitive effect. This material has the great potential as a practical high-rate anode material for lithium-ion batteries.Jiaqin Liao Rou Tan Zhixiang Kuang Chunyu Cui Zengxi Wei Xiaolan Deng Zhanheng Yan Yuezhan Feng Fang Li Caiyun Wang Jianmin Ma 2018Chinese Chemical Letters2018,29,12:1
