An indefinite region disaster simulation model is established, in which model, a computational grid simplification model is proposed, human-computer interaction and cellular automaton technologies are adopted to deal with the closing boundary problems, fine feasibility of the disaster simulation model is verified by experiments.
Rate control algorithm is of great importance to video coding. Many existing schemes are based on the quadratic rate control scheme. The proposed method introduces a novel rate control algorithm with adaptive rounding offset, aiming at achieving bit-rate optimization and adaptation of the content of the video sequences. The rounding offset is chosen adaptively based on the minimum blocks' discontinuities...
In energy constrained wireless sensor networks, node scheduling is an effective approach to improving the energy efficiency and prolonging the network lifetime. In this paper, we propose a distributed, lightweight, and location-unaware scheduling scheme for randomly deployed wireless sensor networks. The basic idea of the scheduling scheme is to organize sensor nodes into disjoint node sets, which...
Many experiments have verified that Sabina vulgaris shrubs had distinguished advantage in anti-drought, but a lot of past works were primarily focused on its eco-physiological characteristics, with its growth model almost never explored. In this work, the primary model of S. vulgaris shrubs is discussed and improved based on the dual-scale automaton model with the data from experiments. The diversification...
FAST TCP is a newly developed transfer control protocol for future networks with high bandwidth delay product. At present, analyzing the stability of FAST TCP in different networks is an active research area. We establish a group of nonlinear delay differential equations to describe the window adjustment algorithm of FAST TCP and the queuing behavior of routers in single-link multi-source networks...
The tall building push-over analysis program (TBPOA) puts forward precise, concise and practical ways of 3D push-over analysis and static elasto-plastic analysis for reinforced concrete tall buildings. Column and beam elements of TBPOA are modeled by nonlinear bar units, while wall elements by nonlinear bar units considering shearing deformation. Based on the plane cross-section assumption, surface...
Thanks to its significant value in anti-drought, Sabina vulgaris is becoming more and more important. But much of past research work was primarily focused on its eco-physiological characteristics while ignoring its basic topological architecture and growth rules. In this work, a dual-scale automaton model is presented to investigate the topological architecture of S. vulgaris shrubs. In comparison...
The regular pattern of temperature change in a coalfield fire area while the fire is being extinguished was studied. To determine the extinguishing effect, a series of linear, logarithmic, polynomial or exponential mathematical regression models were constructed using the observed temperature data from the Xinjiang coalfield fire extinguishing project. The quadratic polynomial mathematical model had...
