Indoor positioning systems are becoming increasing popular recently. While most existing indoor positioning studies focus on improving accuracy, less attention is paid to the latency problem. The traditional fusion algorithm uses the received signal strength‐based (RSS‐Based) positioning result to correct the current position of the system. However, it fails to keep up with the actual moving speed...
For the swing problem of ocean buoy under billowy environment, which is hard to obtain clear and stable image, this paper designed a kind of PTZ stabilization system platform based on gyroscope and electronic compass module. During the angle data collection process, we adapt accelerometer trigonometric function method to overcome not only the low accuracy problem with a single sensor, but also accumulative...
The tracking of moving biological cells in time-lapse video sequences is fundamental to further understanding biological processes. Automatic cell tracking techniques require accurate cell image segmentation; however, current segmentation techniques are susceptible to errors due to non-ideal but realistic cell image conditions, including low contrast typical of cell microscopic images. This paper...
The purpose of this work is to develop a simple method to incorporate quantum effect in traditional finite-difference time-domain (FDTD) simulators. Which could make it possible to co-simulate system includes quantum structures and traditional components. In this paper, tunneling transmission coefficient is calculated by solving time-domain Schrodinger equation with a developed FDTD technique, called...
