First  two-dimension discrete wavelet transform (DWT) is applied to a nature image for sparse representation. After multi-scale DWT  the low-frequency sub-band and high-frequency sub-bands are re-sampled separately. According to the statistical dependences among DWT coefficients  we allocate different measurements to low- and high-frequency component. Then  the measurements samples can be quantized. The quantize samples are entropy coded and forward correct coding (FEC). Finally  the compressed streams are transmitted. At the decoder  one can simply reconstruct the image via l1 minimization. Experimental results show that the proposed wavelet-based CS scheme achieves better compression performance against the relevant existing solutions.   Dynamic stress and deformation of a layered road structure under vehicle traffic loads: Experimental measurements and numerical calculations 期刊论文  OAI收割 SOIL DYNAMICS AND EARTHQUAKE ENGINEERING, 2012, 卷号: 39, 页码: 100-112 作者:  Wu Wan-ping;  Lu Zheng;  Yao Hai-lin;  Cheng Ping   |  收藏  |  浏览/下载：19/0  |  提交时间：2018/06/05 Layered road structure  Vehicle traffic loads  Experimental measurements  Transmission and reflection matrices (TRM) method  Hankel's transform   3R intersection target positioning in real time based on distance (EI CONFERENCE) 会议论文  OAI收割 2010 International Conference on Computer, Mechatronics, Control and Electronic Engineering, CMCE 2010, August 24, 2010 - August 26, 2010, Changchun, China Nengwei W.; Juan C.; Jian C. 收藏  |  浏览/下载：13/0  |  提交时间：2013/03/25 The positioning error based on angle  angle-distance or single station positioning increases with the distance increasing. 3R target positioning based on distance can obtain the high precision measurements in long distance. Here we give the 3R model for the intersection positioning  provide the two necessary conditions for getting the optimum intersection point. The experimental results show that the intersection precision based on angle is over 2m and will degrade greatly with the increasing of distance while the one based on 3R model will improve and the error decrease gradually. That the precision of the distance measurement is about 1m means the 3R model is better than the angle positioning  which can compensate the drawbacks of the angle positioning at short distance. 2010 IEEE.   Energy upconversion in erbium doped oxyfluoride tellurite glass (EI CONFERENCE) 会议论文  OAI收割 ICO20: Materials and Nanostructures, August 21, 2005 - August 26, 2005, Changchun, China 作者:  Chen B.;  Xie Y.;  Wang X.;  Wang X. 收藏  |  浏览/下载：16/0  |  提交时间：2013/03/25 In this article  we have investigated energy upconversion process in erbium doped oxyfuoride tellurite glasses exciated with 980 nm diode laser. The glasses used in measurements are with a mol% composition of 70TeO2-9PbF2-190AlF3-10BaF2-1Er2O3. The s intensity parameters  the radiative rates  the branching ratios and the fluorescence lifetimes were calculated based upon the Judd-Ofelt theory and the experimental absorption spectrum. Under 980 nm excitation  efficient 530  544  and 665 nm upconversion emission are due to two-photon absorption processes.   Spectroscopic investigations of Er3+ doped Bi2O 3 -B2O3 -SiO2 glass (EI CONFERENCE) 会议论文  OAI收割 ICO20: Materials and Nanostructures, August 21, 2005 - August 26, 2005, Changchun, China 作者:  Chen B.;  Wang X.;  Wang X.;  Wang X.;  Wang C. 收藏  |  浏览/下载：74/0  |  提交时间：2013/03/25 From the optical absorption measurements  the Judd-Ofelt parameters were computed using Judd-Ofelt theory. According to the radiative lifetime obtained from the Judd-Ofelt parameters and the measured lifetime  the 1.5m quantum efficiency was calculated. The quenching effect of OH upon the lifetime of 1.5m emission was investigated. From the absorption sideband measurement of glass host  the value of optical band gap was estimated. The McCumber theory was used to calculate the stimulated emission cross-section and in approximate agreement with experimental one if the emission spectrum could be obtained accurately. The gain coefficient spectra were computed.
