This paper conducts a series of evacuation trials to observe human behavior under different ship rolling angles modeled as a function of wind-wave dynamics. A velocity reduction model is then developed with the consideration of human characteristics, ship rolling angles and wind-wave dynamics. Based on the open source simulation software FDS Evac, the proposed model is implemented and validated through...
The real-time rendering of large-scale terrain has been widely used in driving simulation, virtual battlefields and 3D games. Large-scale terrain holds huge geometric and textural data. How to generate and render large-scale terrain in real time with limited computing resources is a big challenge. Different from the previous out-of-core terrain roaming methods which are based on complex scheduling...
Forest evolution simulation and visualization are challenging tasks in terms of complex interactions at various time and space scales. In this paper we present a forest evolution simulator system, based on individual-based, spatially explicit forest gap model, incorporating with fine-scale process of neighbor competition and understory recruitment. The forest evolution for each growth cycle is visualized...
In this paper, we extend the neural network based approaches, which can asymptotically compute the largest or smallest eigenvalues and the corresponding eigenvectors of real symmetric matrix, to the real antisymmetric matrix case. Given any n-by-n real antisymmetric matrix, unlike the previous neural network based methods that were summarized by some ordinary differential equations (ODEs) with 2n...
