Reflections on gravity and entropy models
Regional Science and Urban Economics, 1975Spatial interaction models are increasingly becoming a descriptive drvice for the dispersion and coherence of activities in a spatial sy~em. The major part of these models derive their theoretical perspective from notions 01 probable interactions over distance and are mainly based on gravity assumptions (or entropy assumptions).

In the last decade, offshore pipeline engineering extended its action field to very deep waters and continental slopes. This implies the necessity to deal with continental slopes instability and mass gravity flows. Even if a standard classification of mass gravity flows does not exist in literature, they can be divided in two main different classes ...

Construction of a Synthetic Earth Gravity Model by Forward Gravity Modelling
2005A synthetic Earth gravity model (SEGM) generates exact gravity field quantities and therefore is well suited to validate methods used in gravity field modelling. This paper describes the construction of a SEGM by forward gravity modelling using available data describing the Earth’s mass distribution.

The Gravity Model in International Trade
2010How do borders affect trade? Are cultural and institutional differences important for trade? Is environmental policy relevant to trade? How does one's income or wage relate to the fact that trade partners are nearby or far away? These are just some of the important questions that can be answered using the gravity model of international trade.
