A simple but efficient non-linear method for 2D inversion of magnetic field data based on Ridge-Regression algorithm

Autor: Ali Moradzadeh, Ali Nejati, Fuad Meysami, Saeed Mojarad

Publikováno v: International Journal of Mining and Geo-Engineering, Vol 55, Iss 1, Pp 73-79 (2021)

In geophysical exploration, inversion is carried out on the observed data to generate a geophysical model, approximating the subsurface geological structure. In the interpretation of magnetic data, the subsurface model parameters are found by a pro

Autor: Abolfazl Asadian, Ali Moradzadeh, Alireza Arab-Amiri, Ali Nejati kalateh, Davood Rajabi

Publikováno v: International Journal of Mining and Geo-Engineering, Vol 48, Iss 1, Pp 1-9 (2014)

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

Adaptive Input-Output Linearization Control of pH Processes

Autor: Ali Nejati, Mohammad Shahrokhi, Arjomand Mehrabani

Publikováno v: Iranian Journal of Chemistry & Chemical Engineering, Vol 27, Iss 3, Pp 25-35 (2008)

pH control is a challenging problem due to its highly nonlinear nature. In this paper the performances of two different adaptive global linearizing controllers (GLC) are compared. Least squares technique has been used for identifying the titration cu
