The inverse problem of Schlumberger resistivity sounding measurements by ridge regression

A Hybrid Algorithm for the Inversion of Direct Current Resistivity and Magnetotelluric Data

“…Gerçek değerler (Slaoui vd., 2003) ve ÇHTB ve TDA ile kestirilen eğri (The field data (Slaoui et al, 2003) and estimated curve by VFSA and SVD) Şekil 4. Slaoui vd., (2003) tarafından verilen verinin ters çözümü (Inversion of the data given by Slaoui et al, (2003))…”

“…Geliştirilen düz çözüm programları kullanılarak DAÖ ve MT yöntemleri için birer adet sentetik ve arazi verisi değerlendirilmiştir. DAÖ yönteminde Slaoui (2003) tarafından verilen veri ters çözülmüştür ve sonuçlar karşılaştırılmıştır. MT yöntemi için ise Meju (1992) tarafından verilen 'Coprod' verisinin ters çözümü yapılmıştır.…”

1D inversion of electromagnetic logs in the characterization of carbonate formations from Santos basin –Brazil

“…The average difference between estimated and true becomes very large. The ridge regression method (Seber and Wild, 1989) seeks to reduce this difference during the damping iteration process of the diagonal terms of ( ) (Hasnaoui et al, 2003). The ridge regression estimates of Δ is:…”

Evaluations of the apparent soil resistivity and the reflection factor effects on the grounding grid performance in three‐layer soils

“…Combined electrostatic images method to evaluate N-layer apparent soil resistivity and interpret sounding measurements by Wenner method is carried out by Lagacé et al [24]. Slaoui et al [25] proposed a method to estimate N-layer soil parameters for the most economical grounding system. Slaoui et al [26] suggested a new method to calculate the apparent soil resistivity of multilayered soils to determine the electrical grounding parameters of N-layered soil.…”
