This paper simulates human visual perception with regard to visual adaptation under the change of illumination. To reflect visual adaptation in scene rendering, we adopt the mathematic models simulating photopic, scotopic, and mesopic vision. We also take consideration the characteristic that adaptation to low visibility takes longer than high visibility. As a result, the outcome of the animation...
This paper deals with the ram-air servo system, a control methodology based on the model-based control of pulse is present, which can linearize the nonlinear servo system. Pneumatic actuators exhibit highly nonlinear characteristics due to the compressibility of air, the complicity of friction and the nonlinearity of valves. To solve these problems, an integral sliding mode variable structure control...
