✦ Synopsis

Two simple methods are presented for Ihe compulation of the density matrix of a localized quantum patiicle. One method is based on a local harmonic approximation and the oiher on a variarional method. which assumes that the density malfix relains a Gaussian runclional form as Ihe lemperalure is decreased

An algorithm is developed for the computation of the transfer function matrix of a two-dimensional system, which is given in its state-space form, without inverting a polynomial matrix. A new transformation has been considered so that the well known Fadeeva's algorithm for regular systems can be use

Alluvial density is an important parameter in hydrogeologic surveys. These density values are often difficult and expensive to obtain, especially in the large Basin and Range province of the southwestern United States. Various methods are available for obtaining densities; however, many are complex

A fast Fortran routine is proposed to compute accurately exchange matrix elements which arise in heavy-particle collision theory. The one-electron integrals are evaluated for Slater-type orbitals, centred on each of the two cores, and modified by electron translational factors. The subroutine is des
