On simulated annealing parameters in Gauss wavelet chaotic neural network
2008 Chinese Control and Decision Conference, 2008Co-Authors: Yaoqun XuAbstract:Wavelet chaotic neural networks have successfully solved function and combinatorial optimization problems. Gauss wavelet chaotic neural units with the annealing function of Subparagraph index were studied. The reversed bifurcation and Lyapunov exponent figures were respectively given. On the basis of Gauss wavelet chaotic neural network, the annealing function of Subparagraph index was introduced into network, a new reformative wavelet chaotic neural network was presented. Then it was applied to function and combinatorial optimization problems. The simulation results show that the search-optimization capacity of wavelet chaotic neural network has been improved and the reformative wavelet chaotic neural network is superior to the primary wavelet chaotic neural networks.

Study on Astronomical Solar Radiation over Rugged Terrain Using DEM Data
2009 First International Conference on Information Science and Engineering, 2009Co-Authors: Shaogang WangAbstract:This paper is based on a distributed model for calculating daily astronomical solar radiation with a resolution of 90mx90m SRTM (Shuttle Radar Topography Mission) DEM. Using ray-tracing method and integral by Subparagraph to calculate the conditions of terrain shading information, and through an integral way to make a visualization of astronomical solar radiation. The result shows that the geographical and topographical factors do visible effect to the spatial distribution of astronomical solar radiation over rugged area.

Astronomical solar radiation simulation based on DEM in Wuyishan mountainous areas
International Conference on Earth Observation Data Processing and Analysis (ICEODPA), 2008Co-Authors: Shaogang Wang, Ding-sheng Liu, Xiaoqin WangAbstract:Digital Elevation Models (DEM) data (90mx90m) reflected by the NASA Shuttle Radar Topography Mission (SRTM) are used as basic information source to overlay digital slope models and digital aspect models, which are applicable to the mountainous terrain of astronomical solar radiation distributed model. This paper uses ray-tracing method and integral by Subparagraph to calculate the conditions of terrain shading information, and through an integral way to make a visualization of monthly astronomical solar radiation (ASR). The result shows that the geographical and topographical factors do visible effect to the spatial distribution of astronomical solar radiation over Wuyishan area, especially in January, it does the most obvious effect to terrain shading, while in July it does the lightest effect to terrain shading. This method can accurately reflect regional differences of solar radiation, and through accumulating daily solar radiation in the region, we can obtain the total amount of solar radiation in every month of the year. This result can provide prerequisite conditions as an important reference and then be useful to biomass estimating of vegetation, agricultural production, climatic resources development and exploiture.
