The friction force and torque between tires and ground effect the motion states of vehicles directly. Controling the force and torque is one method of stability control of vehicle. The feasible region of combined force and torque determines the limits of the vehicle motion states, and it is important to the stability control system design. The way of distribute the force to fore tires is also important...
HF channel sounding requires perfect autocorrelation property of the sounding sequences. Compared with other pseudonoise sounding sequences, Zadoff-Chu sequence gets great attention due to its predominant periodic autocorrelation property. In order to adapt the spectrum property of Zadoff-Chu sequence to the requirement of HF channel sounding transmitter-receiver, the Formula Direct Interpolation...
Overweight and obese students in school as a relatively special group, overweight and obesity have become the obstacles in his (her) healthy growth, how to improve this population's physical and mental health is the important prerequisite to enhance the health level of students in our country. This study aims to intervene in overweight and obese female college students by exercise plus balanced diet...
In this paper, the inherent characteristics of vulnerable groups, from the practical and research needs, the disadvantaged groups to participate in sports activities and countermeasures to this problem, the author discussed from two aspects, and explain, first, through a comprehensive understanding of the vulnerable families groups currently participating in sports activities as well as the practical...
In order to detect various kinds of malicious attacks in wireless sensor networks we proposed a Trust Model based intrusion detection scheme which meets the efficient lightweight and flexible property in this paper. It makes use of some nodes with high trust degree to monitor the whole cluster decreasing the huge power consumption and prolonging life of the whole networks. We propose an algorithm...
