Multipath transmission is the important way to increase the efficiency and reliability of network transmission. Along with the development of overlay network, multi-homed host et al, multipath transmission control becomes the hot spot of network transmission technology research gradually. As the base of path choice and switching in multipath transmission, real-time evaluation of path QoS is a key...
An intelligent system of X-ray framing camera is designed and realized to fulfill the demand of being intelligent and automotive in the diagnosis system for Inertial Confinement Fusion (ICF). Being controlled by PC104 embedded host computer and combining with Interface Card, the camera system can achieve human-computer interface interactive, networking, camera working point setting, mode switching...
In this paper, the coarse acquisition code (C/A code), which is for civil navigation, of the ranging codes for Global Positioning System (GPS) is studied, simulated and analyzed by the Use of Matlab. With the simulation results we can confirm the correctness of the method and feasibility, which is at simulation platform to further study on the real environment of GPS signal, so That it can capture...
ZigBee standard is a developing low-cost, low power consumption, short-distance wireless communication standard and routing algorithm improvement plays an important part in updating the protocol. Based on the analysis of existed ZigBee routing algorithm, this paper proposes an improvement by comprehensive using of Cluster-Tree algorithm and the "piggyback" technology to increase effective...
According to the problem of the intervals of traditional traffic information collection technologies based on GPS equipped floating car chose by experience, or on which theoretical researches divorcing from reality at different degree, the optimization technologies for the sampling interval and transmitting interval are designed considering the influencing factors and verified with measured data....
This paper presents a roll state estimator and a rollover prediction model based on a real-time roll estimator. The real-time roll estimator is designed to estimate the current roll angle and roll rate of the vehicle body from a 3DOF vehicle model. The veDYNA dynamic simulation software was used to verify the performance of roll motion prediction. The prediction model calculates the time it takes...
