This work is an experimental study on percolation and electrical conductivity in two-dimensions with an aim of confirming some of the theoretical predictions, and measuring some of the parameters introduced in the theory. These parameters include the percolation threshold p , the critical...

The need to determine constituent elements in materials so as to meet various technological demands in many fields is of an extreme importance. This work is an attempt to establish the efficacy of using non-destructive neutron activation methods based on instrumental gamma-ray spectrometry for...

The ordinary time-independent Landau problem of a charged particle moving in an external perpendicular homogeneous magnetic field and the case of when a linear potential is introduced are reviewed for motion occurring in an infinite plane, on an infinite strip and in the half-plane. The first...
