Hemodynamic indexes will change significantly compared to the normal range of many vascular diseases, therefore it is necessary to establish hemodynamic computation model. Blood circulation is periodically forced huge fluid flow network, the heart is generator of the entire fluid network, based on this hemodynamic characteristics, the circle of Willis’s structure is simplified from the perspective...
In view of distribution according to complex fluid network’s needs, this paper proposed one optimization computation method of the nonlinear programming mathematical model based on genetic algorithm. The simulation result shows that the overall energy consumption of the optimized fluid network has a decrease obviously. The control model of the fluid network is established based on nonlinear dynamics...

The harmony search algorithm was used to find the global optimal solution of the network. An improved harmony search through proper...
In the robot vision, the color is the essential information in the object recognition and cognition process. Here proposed one kind object identification algorithm based on the color characteristic with the YUV color space, uses the study - expansion algorithm to obtain the spatial distribution of the compatible object color characteristic, overcomes the influence that the environment illumination...
A mathematical control model of blood flow through the circle of Willis was developed, within a nonlinear framework. Based on system's viewpoint, the circle of Willis is fluid network system that is composed of four entrances and three communicating arteries. A nonlinear model is established for fluid network systems using lumped parameter approximations of incompressible Navier-Stokes equations and...
In this paper, the adaptive fuzzy fault-tolerant voting mechanism has been proposed based on EKF, which can solve the bottleneck problem of voting when there are many fault-tolerant gyroscopes floating point input signals. Through connecting EKF in the original fuzzy voting mechanism, the adaptive fuzzy fault-tolerant voting mechanism has prevented the flaw that the fuzzy voting is unable to judge...
Based on system's viewpoint, the cerebral circulation of Willis is fluid network system that is composed of four entrances and three communicating arteries. Using lumped parameter approximations of incompressible Navier-Stokes equations and the graph theory of the circuit network, a nonlinear minimal model is established for fluid network systems. This model provides the basis for the entire cerebral...
