On aviation mapping  compression image maybe not decode because of wireless transmission interference. UEP(Unequal Error Protection) scheme is put forward about layer and block structure of JPEG2000 image compression method  flexibly enhances local reconfigurable image's quality which is in favor of identifier in the region of interest. 2008 IEEE.  and realizes three degrees UEP of data block  data header  image data via various degrees correction-coding under the condition of obstruct  naked and shade. BCH  RS and Hamming coding are simulated  and image decoding success rate and image's quality are analyzed according to different coding and ROI (Region of Interest) in the Gaussian white noise model and rayleigh fading model. Results shows that the method we putted forward roughly improves decoding success rate  at the same time  almost not increasing bandwidth

We determined the optical constants (the refractive index n and the extinction coefficient k) of ion beam sputter deposited zirconia thin films with spectroscopic ellipsometry (SE). First  we obtained the structure information (the layer thickness  surface roughness and layer diffusion) by fitting the grazing x-ray reflection (GXRR) spectra. The fitted surface roughness is verified by atomic force micrometer (AFM) measurement. Second  based on the acquired structure information  the measured ellipsometry spectra are fitted in the range of 240-800nm at an incident angle of 70.25 degree. The optical constants are solved based on the Tauc-Lorentz dispersion. The optical band gap extracted by SE is 4.79eV. Finally  the optical band gap is verified by Taue plot method  which is well consistent with that of SE.  
Research on the airborne communication and navigation apparatus ATE system based on the virtual instrument (EI CONFERENCE) 会议论文

The airborne communication and navigation (CN) apparatus ATE system is the important apparatus for measure the working state and performance of the CN automatically and quickly. It has explained the composition of the ATE system based on the virtual instrument  the bus structure and signal recuperated in this paper. The ATE System adopts platformization fault diagnosis thought  the fault diagnose mechanism and logic are designed by the users  which is an organic whole realized the fault diagnoses and the maintain means coordination. System is interchangeable and upgradeable on operating system  special-purpose tester  and the testing program is portable between the different ATE. Indicate by the practice  the airborne CN apparatus ATE system have good military and economic benefits. 2008 IEEE.
