Quad surface charge is adopted in the charge simulation method (CSM) to simulate the electric field under HV transmission lines in the vicinity of buildings. First, a semi-analytical integration strategy is proposed in the calculation of potential and field strength coefficients. Then, an experiment is designed to testify the method. Finally, the electrostatic field computation effect around an actual...
A zero element row augmenting path algorithm is proposed for linear assignment problems. Under the algorithm, the maximum element in an assignment y is picked firstly, where y is calculated according to the reduced matrix of a given cost matrix at the initial stage. According to each row's zero element record and starting from the row containing the picked element, a zero element row augmenting path...
Motivated by the desire to obtain the interior layout of a building from through-the-wall radar measurements, we have developed a building layout reconstruction algorithm based on the minimum spanning tree (MST), which is a graph-theoretical method. Based on the extraction of all the wall-wall-floor trihedrals from radar measurements, we have defined the vertex and edge set of the building layout...
Driver assistance system is currently an active research and development field for the general goal to provide useful information to drivers in order to reduce the number of injuries and fatalities in traffic. One important component of future systems will be an accurate and reliable positioning, which can be realized by relative measurement, using onboard sensors and maps of the environment. This...
Urban agriculture is an integrative concept which encompasses economy, society, ecology, landscape, education, demonstration, et cetera. However, the research on the application of urban agriculture to ecological residential district planning is still rare now. This essay first describes the origin, development, characteristics and multi-function of urban agriculture, then presents the significance...
This paper firstly introduces the Clean Development Mechanism (CDM) and presents the situation of iron and steel industry CDM project. Then it further studies methodologies on the assessment of the influence of CDM projects on sustainable development, analyzes and evaluates CDM projects effecting China's iron and steel industry sustainable development on the case of Wugang Coke Dry Quenching project...
Recent years LiDAR data is widely used for constructing 3D terrain models which provide realistic impressions of the urban environment. This paper presents an automatic method for extracting 3D building model by the fusion of LiDAR data, 2D building outlines and orthoimage. 2D building outlines is generated by classifying the LiDAR data to terrain and off-terrain points, then detecting building edges...
