This paper focuses on the numerical study of heat and moisture transfer in clothing assemblies, based on a multi-component and multiphase flow model which includes heat/moisture convection and conduction/diffusion as well as phase change. A splitting semi-implicit finite volume method is proposed for solving a set of nonlin-ear convection-diffusion-reaction… (More)
In this talk, we present our recent work on moisture transport model in fibrous clothing assemblies in a one dimensional setting. We formulate this problem as multi-phase flows in fibrous porous media with phase change. The model is based on a previous study with significant modification to take into account the air resistance to moisture transport as well… (More)
Detections of seven kinds of Chinese traditional medicine were proposed theoretically and experimentally by surface plasmon resonance (SPR) technology in this paper. An optical system based on wavelength modulation was built for the measurement. Factors that will affect the measurement were discussed. The influences of the matching oil and the stability of… (More)
In this paper, we model the magnetic target. Then we use nonlinear least square method to locate the magnetic target and estimate its parameter. The simulation results show that the nonlinear least square method can work well when the signal to noise ratio is greater than 6dB.
Two well-known polarization-maintaining photonic crystal fibers were investigated by introducing some deformations in their air hole claddings. Variation of size and position of the cladding air holes could change the effective indexes of the fundamental guide modes of the deformed fibers, so change the zero dispersion wavelengths. In addition, the… (More)
