The facies distribution in time and space of sedimentary successions is controlled by a complex interplay between physical, chemical biological processes, which are nowadays difficult to construe from the geological record. Numerical models constitute valuable tool identify quantify such controlling factors permitting reliable 3D extrapolation prediction stratigraphic architectures beyond outcr...

This paper briefly considers the application of the principles of Empirical Modelling to an analog mechanical computer of WWII, and puts forward the theory that this primitive early computer, that followed such different principles to today's all-purpose computers, had properties of its design in common with EM models. The computer and system in question are related briefly to the principles of...

Original scientific paper Traditional dc electrical exploration method will face great challenge when detecting deep, complex geologic target. With the purpose, forward modelling and inverse modelling method of borehole resistivity has been developed. According to the characters of geology, the geological model has been set up. The numerical simulation shows that borehole resistivity method is ...

We describe the decomposition of QSO absorption line ensembles applying an evolutionary forward modelling technique. The modelling is optimized using an evolution strategy (ES) based on a novel concept of completely derandomized self-adaption. The algorithm is described in detail. Its global optimization performance in decomposing a series of simulated test spectra is compared to that of classi...
