dc motion of ac driven sine-Gordon solitons
(Elsevier, 1998-10-05)
We investigate the dependence of dc soliton motion sustained by pure ac driving in the sine-Gordon model on various parameter problems, such as frequency, initial kink velocity or relative phase. We show by means of the ...

Numerical Simulation of Electric Currents through Insulating Materials
(IEEE, 1998)
A numerical simulation of electric currents is carried out through solid dielectrics from a model based on the local polarization. A degradation of material was considered to be produced from one of the electrodes and ...

Three-dimensional modelling of the tide-induced dispersion of radionuclides in the sea
(Elsevier, 1998)
A three-dimensional marine dispersion model for radionuclides has been developed. ¹he model solves the three-dimensional hydrodynamic equations and, simultaneously, the three-dimensional advective—diffusive dispersion ...

Soil to plant transfer of 226 Ra in a marsh area: Modelling application
(Elsevier, 1998)
¹he Odiel river forms an estuarine system which surrounds a large marsh area. A phosphate fertilizer processing complex releases its wastes into the estuary. ¹he presence of 226Ra in soils and plants (Spartina Densiflora) ...

Software de dominio público: una alternativa de coste cero para la docencia
(Universidad de Las Palmas de Gran Canaria, Servicio de publicaciones y producción documental, 1998)
En la actualidad, la necesidad de la utilización de los ordenadores como soporte fundamental para la docencia se ha hecho evidente. Ello se debe tanto a la implantación de estas máquinas en entorno empresarial ...

Kinetic transfer coefficients for radionuclides in estuarine waters: Reference values from133Ba and effects of salinity and suspended load concentration
(Springer, 1998)
In estuarine environments there are important spatial and temporal changes in both salt and suspended load concentrations. An experimental procedure have been developed to produce kinetic parameters being representative ...

Modelling the Distribution of Radionuclides in Deep Ocean Water Columns. Application to 3H, 13 Cs and 239, 246Pu
(Elsevier, 1998)
A one-dimensional model to simulate the dispersion of radionuclides down deep water columns has been developed. The model includes the transfers of radionuclides between water, suspended matter and bottom sediments. Such ...

A three dimensional σ-coordinate model to simulate the dispersion of radionuclides in the marine environment: application to the Irish Sea
(Elsevier, 1998)
A three dimensional model to simulate the tide induced dispersion of radionuclides in the sea has been developed. The model uses normalized σ-coordinates in the vertical so that resolution is not reduced in the shallower ...

Steady state of a fluidized granular medium between two walls at the same temperature
(American Physical Society, 1998)
The steady state of a low-density gas of inelastic hard spheres confined between two parallel walls at the same temperature is studied. Because of the dissipation in collisions, the state is not uniform but highly inhomogeneous ...
