coastal fars gravimetry project in fars province was carried out to find the buried salt domes and to determine characteristics of faults in this area. the lavarestan structure was covered by 4203 gravimetry stations in a regular grid of 1000*250 m. depth structural model of this anticline made in previous studies was based on geological evidences and structural geology measurements. in order t...

The objective of this article is to review some methodological aspects for inverse modelling of emissions in air quality: how to characterise emissions on the basis of observed data and model outputs? Three examples, provided by recent works carried out at CEREA, Joint Laboratory ENPC/EDF R&D, illustrate these topics, inverse modelling of radionuclides at short scales, inverse modelling of NOx ...

the helicopter-borne electromagnetic (hem) frequency-domain exploration method is an airborne electromagnetic (aem) technique that is widely used for vast and rough areas for resistivity imaging. the vast amount of digitized data flowing from the hem method requires an efficient and accurate inversion algorithm. generally, the inverse modelling of hem data in the first step requires a precise a...

This paper presents the design and implementation of a systematic fuzzy modelling methodology for the inverse dynamic modelling of robot manipulators. The fuzzy logic modelling methodology is motivated in part by the difficulties encountered in the modelling of complex nonlinear uncertain systems, and by the objective of developing an efficient dynamic model for the real-time model-based contro...

A mass balance inverse modelling procedure is applied with a time-dependent methane concentration boundary condition and a chemical transport model to relate observed changes in the surface distribution of methane mixing ratios during the 1990s to changes in its surface sources. The model reproduces essential features of the global methane cycle, such as the latitudinal distribution and seasona...
