Gravity inversion of basement relief using imperialist competitive algorithm with hybrid techniques
Autor: Ali Nejati, Amir Joolaei, Ali Reza Arab-Amiri
Publikováno v: Acta Geophysica. 70:2629-2646
Classically, local deterministic optimization techniques have been employed to solve such nonlinear gravity inversion problem. Nevertheless, local search methods can also be easily implemented and demonstrate higher rates of convergence; but in highl

Combining a robust PCA of logratio transformed data and geostatistical sequential Gaussian simulation approach for geochemical characterization of orogenic gold deposits: a case study from the Alut area, NW of Iran
Autor: Masood Alipour-Asll, Ali Reza Arab-Amiri, Abolghasem Kamkar-Rouhani, Fereydoun Sharifi
Publikováno v: Geochemistry: Exploration, Environment, Analysis. 20:1-13
Robust principal component analysis (PCA) has been proved to be an efficient multivariate statistical method for extraction of a multivariate structure of geochemical data containing outlier values. Furthermore, because of the compositional character

Development of a novel approach for recovering SIP effects from 1-D inversion of HEM data: Case study from the Alut area, northwest of Iran
Autor: Abolghasem Kamkar-Rouhani, Ali Reza Arab-Amiri, Ralph-Uwe Börner, Fereydoun Sharifi
Publikováno v: Journal of Applied Geophysics. 174:103962
We have developed a novel approach for recovering the induced polarization (IP) effects from one-dimensional (1-D) inversion of helicopter-borne electromagnetic data (HEM). To achieve this aim, we incorporate both electromagnetic and spectral induced
