Baker transformation is sensitivity to initial value. When the initial value takes different value, the result is that tending to being restrained in the attractor, the periodic orbit, entering the chaotic state. When encrypting image by Baker transformation, the more scrambling, loss of information is also more.
In this paper, we study the whole situation for space debris. The space debris is analyzed based on the model with MASTER-2009. The impact argument of true latitude and object diameter are enumerated. Combining the dynamics of the spacecraft orbit and the property of the space debris, the threat modeling from the space debris to spacecraft is formulated, and the Visualization simulation results are...
The modern intelligent parking management system is a combination of various functions of subsystems. In order to solve the deficiency of artificial management on efficiency, security, performance and management in the traditional parking lot, this article designs a relatively independent vehicle positioning subsystem by constructing a ZigBee wireless network, using wireless sensors to capture vehicle...
In allusion to problems of larger vehicle distance, low march speed, length march, inconvenient correspondence and command, and fatigue easily, this paper puts forward an assume designing an announciator of motorized mobility vehicle, analyses and researches its necessary and primary function, and designs the structure and constitutes of the announciator.
