In dusty plasma experiments, the confining potential of the GEC rf Reference Cell is commonly assumed to be parabolic. There are various ways to test this assumption, many of which interfere with the plasma. We use the noninvasive method of perturbing a single particle suspended in the plasma with laser pulses. In this experiment a cw laser (532nm, 0.01.05W) supplied the radiation pressure forc...

Monte Carlo simulation of photon scattering, with and without abnormal tissue placed at various locations in the rectangular, semi-circular and semi-elliptical tissue models, has been carried out. The absorption coefficient of the tissue considered as abnormal is high and its scattering coefficient low compared to that of the control tissue. The placement of the abnormality at various locations...

In this work, XFEM is employed to obtain the stress intensity factors (SIFs) of a semi elliptical part through thickness axial crack. In XFEM, additional functions are employed to enrich the displacement approximation using partition of unity approach. Level set functions are approximated using higher order shape functions in the crack front elements to ensure the accurate modeling of the crack...
