Variational methods in geosciences : proceedings of the International Symposium on Variational Methods in Geosciences held at the University of Oklahoma, Norman, Oklahoma on October 15-17, 1985

The last few decades have seen a spectacular growth in the use of variational methods, one of the most classic and elegant methods in physical and mathematical sciences, as powerful tools of optimization and numerical analysis. The tremendous accumulation of information on the use of variational methods in the area of the geosciences, which includes meteorology, oceanography, hydrology, geophysics and seismology, indicated the need for the first symposium on Variational Methods in Geosciences to be organized and held in Norman on October 15-17, 1985. The value of this symposium was enhanced by the number of stimulating and informative papers presented Content: Further titles in this series Page II Front Matter Page III Copyright page Page IV Sponsoring Organizations Page V Committee Members Page VI Preface Page VII Yoshi K.

Describes the various advances theoretical geostatistics, which have practical applications in ore reserve estimation. This book addresses the problems commonly encountered in the practice of orebody modelling when the data do not conform to the early theoretical models. Real case studies are presented in every chapter using well-known deposits.
