The spin-3 2 Ising model Hamiltonian with arbitrary bilinear (J) and biquadratic (K) pair interactions is studied by using the lowest approximation of the cluster variation method (LACVM) and the path probability method (PPM) with the point distribution. First, equilibrium properties of the model ar

The critical behaviour of the bond and site dilution transverse Ising model on a square lattice with spin-l/2 is investigated within the framework of the finite cluster approximation (FCA). The phase diagrams, critical temperature, critical transverse field and percolation threshold are given. The F
Path integration (dead reckoning) is a computational process by which an animal can keep track of its position relative to some starting point by relying on self-generated information collected en route. The purpose of this paper is two-fold: first, to review four important models of path integratio
