It can deal with all bit-planes simultaneously  and process in the speed of 4pixels/period  so the encoding time is only relative to the image resolution. The experimental results show that  the processing capacity can achieve 200MPixels/s  when the input clock is 50MHz  the system of this paper need 2.29ms to complete lossless compression of a 512x512x8bit image  and only requires 1.31ms in the optimal state. The improved algorithm keeps the high SNR unchanged  increases the speed greatly and reduces the size of the needed storage space. It can implement lossless or lossy compression  and the compression ratio can be controlled. It could be widely used in the field of the high-speed and high-resolution image compression. 2010 IEEE.   The research of control strategy on AOD furnace tilting system (EI CONFERENCE) 会议论文 2010 International Conference on Logistics Systems and Intelligent Management, ICLSIM 2010, January 9, 2010 - January 10, 2010, Harbin, China Ma H. T.; You W.; Chen T. 收藏  |  浏览/下载：13/0  |  提交时间：2013/03/25 In view of the low speed  the heavy load  reversing  the frequently brake  the intense impact characteristics of AOD furnace tilting system  The double closed-loop with feedforward is used. Position regulator and speed regulator use PID algorithm.And the speed loop is designed  based on vector control. This control system was simulated by MATLAB Simulink software. The simulation result showed: Adjustment time is 8s  the position steady-state error is 0  so it has achieved the demanded target of 0.12 radian static error fully. 2010 IEEE.   The Simulation measurement experiment and calibration for Solar Total Irradiance Monitor on board (EI CONFERENCE) 会议论文 ICO20: Remote Sensing and Infrared Devices and Systems, August 21, 2005 - August 26, 2005, Changchun, China Yupeng W.; Wei F.; Bingxi Y. 收藏  |  浏览/下载：29/0  |  提交时间：2013/03/25 STIM (Solar Total Irradiance Monitor) can be used on sun-synchronous polar orbit weather satellites to measure the total solar irradiance. It contains three independent and identical wide view absolute radiometers. They are mounted on the satellite in an angle which ensure the sun scan over the field of view of the absolute radiometers. This measurement method doesn't need the instrument tracking the sun but the sun scan over the field of view of the absolute radiometers in each orbit cycle. The paper presents the measurement method of simulation for solar irradiance measurement and calibration by mounting the instrument on a two-axis rotation table. By controlling the rotation angle velocity of the instrument in the meridian direction being the same as that of the weather satellite's on orbit  we can measure the solar irradiance when the sun scan over the field of view of the absolute radiometers to simulate the onboard state. And we have operated the measurement with the prototype of STIM. The SIAR-1 is traceable to WRR and serves as a transfer standard. So simultaneous comparison measurements between SIAR-1 and each of the three wide view absolute radiometers are measured to provide calibration corrections to the instrument. And we have a further study at the influence of stray light to the measurement results. This paper presents the method of simulation experiment and calibration for solar irradiance measurement with Solar Total Irradiance Monitor on board.
