The purpose of this study is to determine the sleep status of college students. 12 volunteers(mean ± SE: 22 ± 2 yr, 170 ± 10cm, 61 ± 16 kg) take part in the research. The sleep situation are got by the waistband sleep monitor system. The average heart rate of the whole night, the average breath rate of the whole night, bed time, get up time, onset latency, total sleep time are monitored. These important...
To avoid the problems caused by complex sea conditions, like high costs, ships passive movement could not be controlled that brought by the ship experiment, in this paper, a simulated ship motion model system is developed to resolve this problem, which improved the reusability and reduced the actual cost. Six degrees of freedom movement mathematical model and sea state interference model are established...
This paper presents a multi-functional marine environment monitoring system based on optical fiber transmission, analyzes the major hardware and software. This system has the functions of real-time detection, visual inspection and sampling inspection.
In an embedded system, the hardware resources are limited. In order to obtain such traffic information as traffic volume and vehicle speed in an embedded system, a series of efficient video processing algorithms and optimization techniques are proposed. The key algorithm to detect vehicles is the background subtraction method, in which the approximated median filter is applied to obtain the simulated...
