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 comprehensive survey of the up-to-date methods and technologies of forest fire detection and monitoring based on wireless sensor network (WSN) is presented. This paper discusses and analyses the system frame and the key problems of WSN-based forest fire monitoring, it focuses on the forest fire forecast modeling, WSN nodes deployment, WSN nodes and forest(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)
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)
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)
Some mode characteristics are obtained by the full vector supercell overlap method that has been developed to model triangular lattice elliptical hole photonic crystal fibers regardless of whether the light is guided by total internal reflection or a photonic bandgap mechanism. When the central defect hole is large enough, the modes are disordered.(More)
