Spatial Differentiation Of Heritage Trees In The Rapidly-Urbanizing City Of Shenzhen, China, Po Ying Lai, Cy Jim, Guang Da Tang, Wen Jun Hong, Hao Zhang
Faculty of Design & Environment (THEi)
In China, heritage trees are actively surveyed and reported. Over 300 relevant published articles were reviewed to assess the contents, trends and geographical distributions of the investigations. The majority of the heritage trees studies in China were found in the eastern provinces and published within 2010–2014. Most studies reported surveys on all old trees. For studies focused on single species, Ginkgo (Ginkgo biloba) and Chinese Yew (Taxus chinensis) was most frequently reported. Unlike the champion tree registry in the US and other countries, the tree registry in China emphasized more on the tree age than the size. We then have …

Spacetime Groups, Ian M. Anderson, Charles G. Torre
Publications
A spacetime group is a connected 4-dimensional Lie group G endowed with a left invariant Lorentz metric h and such that the connected component of the isometry group of h is G itself. The Newman-Penrose formalism is used to give an algebraic classification of spacetime groups, that is, we determine a complete list of inequivalent spacetime Lie algebras, which are pairs (g,η), with g being a 4-dimensional Lie algebra and η being a Lorentzian inner product on g. A full analysis of the equivalence problem for spacetime Lie algebras is given which leads to a completely algorithmic solution to the …

Integrated Database System With Spatial Information For Disaster Risk Management, Ever Enrique Castillo Osorio, Bashir Hayat, Babar Shah, Francis Chow, Ki Il Kim
All Works
© 2019 AECE. Despite availability of various image sources for specific areas, a new disaster management system is likely to be implemented by using only one of them. Thus, its applicability and extensibility are severely limited. In addition, real-time update for the disaster area is one of the crucial functions for search and rescue activities. To meet the aforementioned requirements, in this paper, we propose a new spatial data infrastructure by defining the methodological scheme for the raster information. The proposed system has four respective layers to reduce the management cost as well as provide a flexible architecture. In each …

Determination Of The Influence Of Spin-Off Roundess On The Value Of Spinning Yarn During Spinning, S.X Babadjanov, F.F Isxakova
Central Asian Problems of Modern Science and Education
The article presents the results of studies of the influence of the unevenness of roundness of the spinning rings on the tension of the yarn produced. It is also noted that if the shape of the ring is distorted, then the slider's trajectory is not a circle, but some closed curve that follows the shape of the ring, while, in general, at each subsequent time, the slider moves along a curve with a different curvature radius. The design scheme and the method for calculating the tension of the yarn from the profile of the ring are given.

EGS Content
Microgravity investigations are key to understanding the behavior or regolith, or dusty granular material, that is ubiquitous on planetary surfaces. We see features on other planets that resemble avalanches and landslides seen here on Earth, while eroded craters and so-called ponds (smooth level dusty deposits at the bottom of some craters) reveal the action of various regolith flow mechanisms. The SLOPEs experiment was designed by an undergraduate group to address questions on the statics and dynamics of granular matter on the surfaces of small Solar System bodies, including a) the flow behavior of granular material along slopes (landslides and avalanches) …
