In order to improve the lying patient's ride quality, a 2-Dimensional ambulance-stretcher-lying body system model was established, and the optimal controller was designed for the stretcher. Considering ride comfort and driving stability, eight performance indexes were selected. Weighting matrices of standard LQR controllers cannot achieve global optimum. A method of determining the weighting coefficient...
This paper proposed an impact analysis framework of three-dimensional indoor location technology based on RSSI. The impact analysis model is set to compare the location precision under different types of noise. The result illustrate that the designed impact analysis tool achieves the perfect three-dimensional indoor location results combined cost, location accuracy with filter. To reduce the impact...
Many visual devices are applied to mobile phone, PDA, or other products lately. These devices can receive real-time video from wireless network or internet. In order to watch video programs, the video frame size received from various devices must be changed. Although many fast down-scaling algorithms have been proposed, most of traditional schemes focus mainly on downsizing the video by an integral...
Recently, many visual devices are applied to mobile phone, PDA or other products. These devices can receive real-time videos from wireless network or internet. In order to watch video programs, the video frame sizes receiving from various devices must be properly changed. Although many fast downscaling algorithms have been proposed, such as SA, AWA and MDN, their performances do not achieve high visual...
