A 3D Sound Simulation System for Flight Simulator
Computer Modeling and Simulation, International Conference on
By Sheng Xiaowei, Zheng Shutao, Han Junwei, Hao Minghui
Issue Date:January 2010
A realistic 3D sound simulation system which is integrated in a flight simulator used for training of pilots is developed. The components of a flight simulator are introduced briefly. To meet the requirements of sound simulation system, Visual C++ and Dire...
Minimum-Congestion Weighted Hypergraph Embedding in a Rings Cycle
Computer Science and Information Engineering, World Congress on
By Qi Wang, Xiaoshan Liu, Xiaowei Zheng, Chunlin Li
Issue Date:April 2009
A rings cycle is an undirected graph obtained from a cycle by replacing each edge of the cycle with a ring so that two rings corresponding to the two end-nodes of any edge have precisely one node in common. Given a weighted hypergraph on a rings cycle, Min...
A 2-Approximation Algorithm for Weighted Directed Hypergraph Embedding in a cycle
International Conference on Natural Computation
By Qi Wang, Xiuheng Zhao, Xiaowei Zheng, Xiaoshan Liu
Issue Date:October 2008
The problem of Weighted Directed Hypergraph Embedding in a Cycle (denoted by WDHEC for short) is to embed the weighted directed hyperedges of a hypergraph as the weighted directed paths around a cycle such that maximalcongestion-the sum of weight of the pa...
