Mysterious and ancient Yuanshui River since ancient times is a major transport arteries into the southwest. The traditional architecture of the Yuanshui river basin is a habitat heritage museum, bearing abundant regional culture, recording social, economic, cultural situation of the Ming and Qing dynasties, and showing the vivacious local culture. Based on the research and combing of Yuanshui River...
In connection with the uncertainty problem of pollutants diffusing in the atmosphere of Wuan city, we monitor and put forward a new conception about air ground pollution belt, and get two-dimensional finite difference equation of air pollution. Meanwhile dispersion coefficient and wind speed are considered as grey parameters. One grey numerical quality model of air pollution is built according to...
In this article, a series of ecological environment problems of Liaocheng city, such as the exploitation of groundwater, water-pollution, air pollution, noise, land salinization, and forest cover rate are discussed in details. Taking these problems into consideration, the author puts forward some feasible strategies and suggestions which can direct the development of eco-environment in a right way...
Because of the uncertainty problem of pollutants diffusing in the atmosphere of Handan city, we monitor and put forward a new conception about air ground pollution belt, and get two-dimensional finite difference equation of air pollution. Meanwhile dispersion coefficient and wind speed are considered as grey parameters. One grey numerical quality model of air pollution is built according to grey theory...
By mean of monitoring SO2 and NOx, we put forward a new conception about air ground pollution belt, and get two-dimensional finite difference equation of air pollution. Meanwhile dispersion coefficient and wind speed are considered as gray parameters. One gray numerical quality model of air pollution is built according to gray theory and applies to the air pollution diffusing system of Handan city,...
Graphs have been widely used to model relationships among data. For large graphs, excessive edge crossings make the display visually cluttered and thus difficult to explore. In this paper, we propose a novel geometry-based edge-clustering framework that can group edges into bundles to reduce the overall edge crossings. Our method uses a control mesh to guide the edge-clustering process; edge bundles...
