In this paper some group-theoretical methods are discussed, which may be used to study both the hyperfine fields on nuclei of crystals, and the interaction of the nuclear resonant radiation with these crystals. Several types of hypertine fields structures are considered. They are: the structure form

Based on a general formulation for discrete-time quantum mechanics, introduced by M. Khorrami (Annals Phys. 224 (1995), 101), symmetries in discrete-time quantum mechanics are investigated. It is shown that any classical continuous symmetry leads to a conserved quantity in classical mechanics, as we
## Abstract A new technique of multiβlevel substructuring based on a regular mesh is presented. The technique takes advantage of the physical symmetry and repetitivity generated by the regular mesh. A special nodeβnumbering/addressing system is developed to exploit the symmetry which results in the
