基于手机数据可靠性分析的旅游城市功能空间识别研究 总被引:1,自引:0,他引:1
随着移动通信和移动互联网的普及,带有地理空间信息的“大数据”受到人文地理学者的关注。本文关注手机移动数据的旅游研究价值,以张家界市武陵源区、慈利县为例,首先分析了通信公司漫游用户数、基站网流量和话务量代表实际游客量的可靠性程度,然后探讨了漫游用户数波动对大尺度行政区的功能空间反映,最后挖掘了网流量波动对小尺度基站区的功能空间识别。结果显示,漫游用户数仅在旅游区对实际游客量具有可靠性,基站网流量比话务量的可靠性更强;漫游用户数在旅游区的波动幅度更大;基站网流量的空间因子分析识别出日常居住区、重点旅游区等功能空间。 相似文献

Studying the volume of ancient pottery vessels can shed light on the development of complex societies and state apparatus
by revealing the means taken to standardize trade and taxation. It can also shed light on the cognitive abilities of ancient
people by investigating their knowledge of computing. This paper explores, as a case study, the volume and shape of the lmlk (“belonging to the king”) royal storage jars, which probably represent the highest level of standardization in eighth century
BCE Judah. To estimate the volume of these vessels we constructed a computer 3D model for each jar. The variation in the jars’
linear dimensions is about 2–3%, a number that is characteristic of human-made objects produced by professionals without employing
measurement tools. Had the potters produced jars of the same height, they could have easily reached 3–4% accuracy in the volume.
Surprisingly, the variation in the jars’ volume is 7–10%. We hypothesize that rather than height the potters focused on the
jars’ shape and wall width, estimating the volume according to the jars’ outer measurements. We propose a simple way that
these measurements could have been taken and suggest a formula that could have been employed by the potters and customers
for quickly calculating a jar’s volume. 相似文献

Physical parameters of petroleum‐bearing fluid inclusions such as bulk density (ρ), molar volume (Vm), vapour volume fraction (?vap) and homogenization temperature (Th) are essential information to model petroleum composition (x) in inclusions and to reconstruct palaeotemperature and palaeopressure of trapping. For the main petroleum types contained in a fluid inclusion, we can follow how ?vap and Th are simultaneously influenced by a change of bulk density in a ?vap versus Th projection. We have correlated Th and ?vap for different petroleum compositions for a large range of bulk density values. However, postentrapment events under new pressure (P) and temperature (T) conditions can greatly modify the initial fingerprints of physical conditions and chemical composition of fluid inclusions. Re‐equilibration is frequent, especially in the case of fragile minerals. Stretching and leakage phenomenon have been simulated using the Petroleum Inclusion Thermodynamics (pit ) software, from virtual petroleum inclusions with known hydrocarbon composition. The aim of these simulations is to understand how ?vap and Th evolve with these re‐equilibration phenomena, with respect to the oil composition. Results of stretching simulations show a characteristic increase of Th and ?vap along correlation curves, with the curve shape dependent on petroleum composition. Leakage simulations show an increase of Th and a smaller increase or even a decrease in ?vap. Consequently, the better preserved inclusions in a given population can be presumed to be those that have the lowest Th. Applications of Th and ?vap measurements of natural inclusions in calcite and in quartz showed that the fragility of the host mineral is a key factor allowing the recording of post‐entrapment events. Inclusions that have stretched or leaked are identified and the best preserved inclusions selected for evaluation of P–T–x trapping conditions. Moreover, petroleum types trapped in inclusions can be identified from ?vap and Th measurements without compositional modelling. 相似文献

Ancient standards of volume: negevite Iron Age pottery (Israel) as a case study in 3D modeling 总被引:1,自引:0,他引:1

Hand-made cylindrical vessels unearthed in excavations of Iron Age IIA sites in the Negev Highlands constitute the largest and most dominant ceramic assemblage of simple-shaped vessels found in Israel. The volumes and linear dimensions of these vessels were analyzed based on computer 3D models reconstructed according to their drawn profiles. This analysis revealed the rules that could have been employed by the ancient potters in order to produce vessels of given volumes. These rules demonstrate the human ability to reveal approximate (but inherent) geometric relationships between form and volume and deploy them in everyday life. 相似文献
