Reconstruction of 3D building objects from 2D drawings is a vital approach for 3D model reconstructing, and the key is symbol recognition of the architectural construction components in 2D graphics. Existing algorithms of graphics symbol recognition are lack of robustness, scalability and with low recognition ability to deal with graphics transformation. This study constructed Attributed Graph to express the geometrical characteristics, topological relationships and semantic characteristics of architectural drawing symbols uniformly. The recognition approach with Attributed Graph can expand easily and flexibly to deal with rotation transformation and scaling transformation. Considering the semantic mapping from drawings to models systematically, created corresponding mapping mechanism to guarantee robustness of model creating system. Achieve internal and external integration of three-dimensional architectural models automatically, by using 3Dmax modeling script. Import models to GeoDatabase, so as to using the model in 3DGIS application.

If " Four faces surrounded by lotuses and three by willows, mountain scenery as the whole city and half covered by lake." is the wonderful portraiture of the Spring city Jinan, then "Every family has springs and willow " is the real description of Hibiscus Street and its surrounding houses. Hibiscus Street is located in the heart of the old city, the residential architecture has been preserved relatively intact. Though Hibiscus Street located in the north, it has characteristics of the southern residential, that is why it has important research values.

A strain of Comamonas testosteroni JA1 known for its capacity to hydroxylate 3‐cyanopyridine to 3‐cyano‐6‐hydroxypyridine was found to be also capable to hydroxylate nicotinic acid at a higher rate. In the course of the induced cultivation the forming 6‐hydroxynicotinic acid was degraded either slightly, in the presence of nicotinic acid in the medium, or faster, in the absence of nicotinic acid. In a combined process of hydroxylation of nicotinic acid by growing culture and hydroxylation of 3‐cyanopyridine by resting cells of Comamonas testosteroni JA1, not only an additional amount of 50.38 g of solid 6‐hydroxynicotinic acid was produced from 1 L of cultivation broth with a 99.97 % molar conversion yield, but also the yield of 3‐cyano‐6‐hydroxypyridine produced was more than doubled. This can be compared to that of the resting cells from the induced cultivation broth where within 8 h an amount of 5.77 g of solid 3‐cyano‐6‐hydroxypyridine was produced by resting cells from 1 L of the cultivation broth. This also was superior to 4.39 g/L of cultivation broth of resting cells reported in the literature.

Coal mining can create a variety of environmental, ecological, and land-use problems. Subsidence areas resulting from coal mining are a common and particularly difficult problem to manage. Despite much discussion in the academic literature as well as among local and international stakeholders, there is neither a uniform standard nor a universally accepted approach for selecting an appropriate governance model for a subsidence area. In particular, the lack of quantitative evaluation methods and excessive subjectivity represent key obstacles to the effective selection of governance models for subsidence areas. This paper proposes a selection framework for a coal mining subsidence governance model that integrates the analytic hierarchy process (AHP) and entropy weight method (EWM). The model comprehensively considers the settlement characteristics of the subsidence area, its geographic location, the water index, as well as the vegetation index. These variables are used as indicators to develop an evaluation framework upon which different subsidence zones can be quantitatively analyzed. The selection framework is demonstrated using examples from three subsidence areas in the Huainan and Huaibei mining areas in China, for which relevant data were collected and processed with the help of field surveys, remote sensing images, and subsidence prediction software. Applying the novel selection framework, the most suitable governance model for each subsidence area was obtained and determined to be consistent with the recommendations of an academic panel composed of multiple experts. The novel selection framework has high efficacy and potential to overcome the problem of subjectivity in the selection of governance models for coal mining subsidence areas. It is also envisaged that future incorporation of the selection framework into a user-friendly software package will significantly improve the efficiency with which suitable governance models for coal mining subsidence areas are selected.

Urban traffic system in Jinan is an vital important sphere to show the city image，as well as a carrier for the local culture. With the development of various lifestyles, it is not merely ornamental, but a cultural experience. At the same time, when the local culture functionality is combined with functionality and times, in order to get a better understanding of it ,modern technology and materials is indispensable to the explore. In this way, citizens will be granted with a better aesthesis.
