Master Thesis Viva in the College of Education for Pure Science entitled ” Spatiotemporal  Interpolation of Fuzzy Regression Models and Kriging Technique for Soil Pollution Data of Metals in Industrial Areas in Mosul City”

The College of Education for Pure Science, University of Mosul, has done the Master Thesis Viva entitled ” Spatiotemporal  Interpolation of Fuzzy Regression Models and Kriging Technique for Soil Pollution Data of Metals in Industrial Areas in Mosul City”

On Thursday, September 14, 2023, the College staff including the respected Dean of the College, Assistant Professor Dr. Qais Ismail Ibrahim, the Honorable Scientific Associate and Administrative Associate, the Honorable Head of the Department of Mathematics, and a number of the college’s teachers were attended the viva

The aim of this study, presented by the Master student Mai Hussein Ali in the Department of Mathematics, is the evaluation of the performance of spatiotemporal interpolation techniques using Kriging spatiotemporal techniques ad Kriging spatiotemporal regression and also using the spatiotemporal fuzzy logic style to obtain the best model. The style used involves the uncertainty information that is represented by the uncertain of the real spatiotemporal data. The data employed in this thesis is the spatiotemporal data of soil pollution in the industrial zones in Mosul city with their real locations and it consists of (192) real observations for the metals of Lead (Pb), Nickel (Ni), Arsenic (As) and Chromium (Cr)

The Kriging spatiotemporal techniques, Spatiotemporal Kriging Regression and the spatiotemporal Fuzzy Logic Style were applied through a mathematical formula and the applications of the Variogram Function that can be obtained as the variance between the observations for all the directions of the compass as well as estimating the variogram function parameters via the results that were reached in this thesis and the covariance models were obtained. Also, Tanaka’s method results are highly similar to the fuzzy linear regression analysis and the calculations were conducted using Matlab language.

The Viva committee was chaired by Asst. Prof. Dr. Mohammed Natheer IsmaeI Qassem / AlNoor University College and the membership of Asst. Prof. Dr. Osama Basheer Shukur / College of Computer Science and Mathematics /University of Mosul, Asst. Prof. Dr. Younis Hazim Ismael / College of Education for Pure Science /University of Mosul and  under the supervision and membership of Lecturer Dr. Ghanem Mahmood Dhahir /  University of Mosul, College of Education for Pure Science.
