The importance of constructing the appropriate Green function to solve a wide range of problems inelectromagnetics and partial differential equations is well-recognized by those dealing with classical electrodynamics and related fields. Although the subject of obtaining the Green function for certain geometries has been extensively studied and addressed in numerous sources, in this paper a syst...

advection-diffusion equation and its related analytical solutions have gained wide applications in different areas. compared with numerical solutions, the analytical solutions benefit from some advantages. as such, many analytical solutions have been presented for the advection-diffusion equation. the difference between these solutions is mainly in the type of boundary conditions, e.g. time pat...

background: consequences of cerebral palsy in adulthood can affect physical, psychological capabilities and quality of life. the purpose of this study was to investigate the relationship between quality of life with spasticity and level of motor function in iranian young adults with spastic cerebral palsy who were community dweller. methods: in an analytical cross sectional study, 77 participan...

We present analytical approximations for the real Kelvin function berx and the imaginary Kelvin function beix, using the two–point quasifractional approximation procedure. We have applied these approximations to the calculation of the current distribution within a cylindrical conductor. Our approximations are simple and accurate. The infinite number of roots is also obtained with the approximat...

background: to investigate thyroid function in preeclamptic patients in comparison with normal pregnant women. methods: in this analytical cross-sectional study free thyroxine (t4), and thyroid stimulating hormone (tsh) levels were measured in 100 preeclamptic patients and were compared with free t4 and tsh levels in 101 normal pregnant women in their third trimester of pregnancy. patients with...

in this paper, unsteady two phase simulation of nanofluid flow and heat transfer between moving parallel plates, in presence of the magnetic field is studied. the significant effects of thermophoresis and brownian motion have been contained in the model of nanofluid flow. the three governing equations are solved simultaneously via galerkin method. comparison with other works indicates that this...

A two-dimensional analytical model for the potential distribution along the bottom channel of the fully depleted region of dual material gate (DMG) SOI MESFET is presented. The potential distribution is modeled by solving the Poisson equation with proper boundary conditions. The model for the potential distribution is extended to derive an analytical expression for the threshold voltage. The ac...

Semianalytical solutions are developed for turbulent hydrogen-air plume. We derived analytical expressions for plume centerline variables radius, velocity, and density deficit in terms of a single universal function, called plume function. By combining the obtained analytical expressions of centerline variables with empirical Gaussian expressions of the mean variables, we obtain semianalytical ...

In this paper, we investigate the AM/AM characteristics of a RoF link in the presence of laserdiode non-linearity. Based on theory, an analytical model of the laser-diode input/output function is developed. The parameters of the function are fitted by translating the parameters of a polynomial fitted to measured results. The analytical and measured results are compared and found to give very cl...
