The geometric percolation thresholds for circular, elliptical, square, and triangular plates in the three-dimensional space are determined precisely by Monte Carlo simulations. These geometries represent oblate particles in the limit of zero thickness. The normalized percolation points, which are estimated by extrapolating the data to zero radius, are etac=0.961 4+/-0.000 5, 0.864 7+/-0.000 6, ...

multi frequency vibrations of a system of two isotropic circular plates interconnected by a rolling visco-elastic layer that has nonlinear characteristics are considered. the system with two circular plates and interconnecting discrete continually distributed rolling visco nonlinear elastic rheological elements presents the model of hybrid nonlinear system. the analytical solutions of first asy...

force convection heat transfer of turbulent nano fluid flow in 90 and 60 degree elbow is simulated by using fluent. single phase model has been implemented to study such a flow field and standard

A simple formulation for studying the free vibration of shear-deformable functionally graded plates of different shapes with different cutouts using the finite element method is presented. The aim is to fill the void in the available literature with respect to the free vibration results of functionally graded plates of different shapes with different cutouts. The material properties of the plat...

Instruments and methods: 1 HNMR spectrum was obtained on a Bruker AV300 spectrometer, and tetramethylsilane was used as an internal standard substance. Matrix-assisted laser desorption/ionization time-of-flight mass spectrometry (MALDI-TOF MS) was recorded on a BIFLEIII instrument. Elemental analysis was performed on a Carlo-Erba-1106 instrument. The aging gel and precipitation was cast on sing...
