Regional geomagnetic field modelling: the contribution of the Istituto Nazionale di Geofisica

open access: yesAnnals of Geophysics, 1997
Models of the geomagnetic field are mathematical expressions able to represent the Earth's magnetic field space and time variations. Time variations on the long term basis are represented by the so-called secular variation.

Modelling mushy regions

open access: yesMathematical and Computer Modelling, 1987
Abstract Two phase or mushy regions in which the phase boundary has a complicated morphology can exist in both pure and impure materials. In the former case, a macroscopic mathematical description can be given for the particular problem of melting by volumetric heating; no such procedure seems available for impure materials and this paper describes ...

An Adjustment Model of Regional Production [PDF]

open access: yesEnvironment and Planning A: Economy and Space, 1985
A model of regional production is proposed which links local output to the distribution of income between owners and workers. In contrast to conventional regional production theories, our model is adjustment oriented, eschewing equilibrium for disequilibrium and certainty for uncertainty.

ESPC-BCS-Net: A network-based CS method for underwater image compression and reconstruction

open access: yesFrontiers in Marine Science, 2023
The Internet of Underwater Things (IoUT) is a typical energy-limited and bandwidth-limited system where the technical bottleneck is the asymmetry between the massive demand for information access and the limited communication bandwidth.
