Summary In order to solve the problem of parameter identification for large‐scale multivariable systems, which leads a large amount computation algorithms, two recursive least squares algorithms are derived according characteristics systems. To further reduce and cut down redundant estimation, we propose coupled algorithm based on coupling concept. By same estimates between sub‐identification estimation subsystem vectors avoided. Compared with proposed in this article have higher...
A silicon-based bilateral diode for fast neutron dose measurement is presented to take advantage of vertical and lateral current distributions achieve high uniform distribution. The structure designed place rectangle p+ n+ contacts on each side the n-Si wafer. Diodes with different parameters are fabricated sensitivity measured. It found that, in this research, increase space between two can effectively sensitivity. Furthermore, decrease contact length density also measured data verified model.
We distinctly reveal the difference in exciton generation processes phosphorescent organic light-emitting devices with an exciplex-type co-host and a single host. Excitons consisting of 4,4,4-tris(N-carbazolyl)-triphenylamine 1,3,5-tris(N-phenylbenzimidazol-2-yl)benzene are created via efficient energy transfer from exciplex to dopant. In contrast, excitons host formed by combination holes electrons trapped dopants. The optimized device utilizing system exhibits highly superior performance...

Based on the calculation of lattice dynamic properties and observation first-order Raman spectra for Zn-Se localized microscopic interface mode (CdSe${)}_{4}$/(ZnTe${)}_{4}$ superlattice, multiphonon (MP) scattering up to five orders has been observed. The linewidth variation with MP order temperature as well frequency intensity behavior can be interpreted by anharmonic decay into extended band modes. These results show defectlike nature interfaces in AB/CD-type superlattices.
Electrostatic discharge (ESD) is a significant cause of yield loss in FPD (Flat Panel Display) array manufacturing. LTPS‐TFT Arrays processing includes series chucking and conveyance steps, which, some these steps would generate triboelectric charge [1, 2]. Although low‐impedance materials for equipment contact parts with glass substrate have been adopted, good grounding has implemented, ESD still happens frequently. In order to understand the root‐cause minimize effect, it necessary...
