To evaluate the accuracy ofisoelectric point determination by capillary isoelectric focusing, the pI values of nine proteins and a peptide, the pI values of which had been determined by other methods and ranging pI 3.55-9.60, were determined by capillary isoelectric focusing by cofocusing of recently developed peptide pI markers ranging 3.38-10.17, and the(More)
Based on supercell lattice method, a novel full vector model is presented to analyze the photonic crystal fibers (PCF). From symmetry analysis of modes of a waveguide, we classify the modes of PCF into nondegenerate or degenerate pairs according to the minimum waveguide sectors and its appropriate boundary conditions. We present the modes of PCF can be(More)
A supercell lattice method, believed to be novel, deduced from the plane-wave expansion method and the localized basis function method, is presented for analyzing photonic crystal fibers (PCFs). The electric field is decomposed by use of Hermite-Gaussian functions, and the dielectric constant of PCFs missing a central air hole is considered as the sum of(More)
In a long period grating (LPG) made on a silica-based single material photonic crystal fibre (PCF), the effect of material dispersion on the resonance wavelength of the LPG is negligible. The resonance wavelength, the period and length of the LPG, and the diameter and pitch of the air-hole lattice of the PCF are found to obey a scaling law that is derived(More)
The effects of fiber structure on Rayleigh scattering were investigated in detail. Some step-index fibers such as GeO2- and F-doped silica-based fibers and total-internal-reflection photonic crystal fiber are examined. The Rayleigh scattering loss (RSL) depends on the fiber materials and index profiles, and different types of fiber have different(More)

It is well-known that the correct diagnosis for wireless sensor network can avoid the paralysis of entire systems. Here, fault diagnosis for wireless sensor network based on genetic-support vector machine is presented in the paper. In SVM, inappropriate training parameters can lead to over-fitting or under-fitting. Thus, genetic algorithm is used to select(More)
A hybrid control scheme is proposed which combines the intelligent sliding mode control and vibration control. Considering the movement of flexible and rotating parts imposes large disturbances on the satellite, and affects the pointing accuracy and stability of attitude, a sliding mode controller is used to eliminate attitude error and ensure system(More)
Growing demand for an efficient land use above and below the ground is motivating cadastre and land management systems to move from traditional 2D systems toward three dimensional ones. Airborne laser technology offers direct acquisition of dense and accurate 3D data. In order to get 3D road this paper proposes a hierarchical algorithm to extract terrain(More)
Spin is an effective way against the laser anti-missile in the first boosting phase. Owing to missile spin, the frequencies of bending vibration decrease in value by spinning speed, and the spinning speed cannot be keep absolute constant in flight. Therefore a time-varying filter network based on the parallel differential spectrum (PD) theory is applied to(More)
The circuit of the signal acquisition module was designed and accomplished based on 24 high-precision A-E type serial A/D conversion chip ADS1258, employed Xilinx xc3s2000 FPGA as acquisition controller embedded in the chassis of N1 Compact-RIO, and host-programmed by Labview. The module achieved 16 Single-Ended input-channels with up to 23.7kHz (maximum)(More)
