For an unmanned marine vehicles, the calculations of its resistance under the water and hydrodynamic coefficients are necessary and important work. For the complexity of the fluid around autonomous underwater vehicles(AUV), the kinematic and dynamic model of underwater vehicles are highly nonlinear and coupled so that the hydrodynamic performance are hardly to be obtained. With the help of computational...
In this paper, we use fuzzy systems theory to convert the technical trading rules commonly used by stock practitioners into excess demand functions which are then used to drive the price dynamics. The technical trading rules are recorded in natural languages where fuzzy words and vague expressions abound. In Part I of this paper, we will show the details of how to transform the technical trading heuristics...
For the aerodynamic parameters identification of projectile and rocket under the influence of random wind, based on the control system sensitivity theory, the formation of the sensitivity and related mathematical models according to realistic systems are formulated. Sensitivity principle of the control system theory is applied to the identification of resistance coefficient. Analyzing missile system...
