Considering that current voltage transformer models of electrical multiple units (EMUs) are narrow-band or models, this paper introduces a wide-band model EMU transformers based on the vector fitting method, circuit synthesis theory and black-box theory. The admittances from 30 kHz to 5 MHz measured by network analyzer, branch in pi-type equivalent calculated according equation two-port circuit...

Vector Fitting is a robust technique for transfer function synthesis in the frequency domain. This method combines the use of a Sanathanan-Koerner iteration and a well-chosen partial fraction basis. It is known that its convergence properties become impaired if the data is contaminated with noise, which results in poor fitting models. In this paper, an alternative approach is presented, and its...

Objective: To develop a lentiviral vector system, which can be used to co-express multiple genes of interest, such as siRNAs cassettes, reporter gene and resistant gene simultaneously and to facilitate to titrate lentiviral vector stock with TCID50 method. Method: Synthesis new multiple cloning sites(MCS)to replace the original MCS of pLKO-1-puro and produced an intermediate plasmid pLKO-1-puro...

The normal vector is one of the metrics that are sensitive to the property of the curved surface. In neuroimage studies, normal vectors are used to strip skulls, to analyze cortical thickness, to assess the principle direction of diffusion tenor and to estimate the location of neural activities. However, conventional methods to estimate the vertex normal on the tessellated mesh are sensitive to...

Fluorescence correlation spectroscopy (FCS) is an increasingly important tool for determining low concentrations and dynamics of molecules in solution. Oftentimes triplet transitions give rise to fast blinking effects, which are accounted for by including an exponential term in the fitting of the autocorrelation function (ACF). In such cases, concomitant saturation effects also modify the ampli...

A new filtering approach designed to eliminate impulsive noise in color images, while preserving fine image details is presented. The computational complexity of the new filter is significantly lower than that of the Central Weighted Vector Median Filter (CWVMF). The comparison shows that the new filter outperforms the CWVMF, as well as other standard procedures used in color image filtering fo...

The present work introduces a modified scheme for the solution of compressible 2-D full Navier-Stokes equations, using Flux Vector Splitting method. As a result of this modification, numerical diffusion is reduced. The computer code which is developed based on this algorithm can be used easily and accurately to analyze complex flow fields with discontinuity in properties, in cases such as shock...
