Prediction of shear wave velocity using empirical correlations and artificial intelligence methods

Validation and application of empirical shear wave velocity models based on standard penetration test

Shear wave velocity is a basic engineering tool required to define dynamic properties of soils. In many instances it may be preferable to determine Vs indirectly by common in-situ tests, such as the Standard Penetration Test. Many empirical correlations based on the Standard Penetration Test are broadly classified as regression techniques. However, no rigorous procedure has been published for c...

Prediction Based Diagnosis Using Artificial Intelligence Methods

Empirical Methods in Artificial Intelligence: A Review

behavior) and analysis of variance, including methods for detecting interactions among variables. A chapter on modeling covers the use of linear regression and related procedures in characterizing system behavior, and the final chapter presents tactics for generalizing from empirical results. One of Cohen’s most important points concerns the goals of empirical AI research. Repeatedly, he asks w...

Empirical relation for estimating shear wave velocity from compressional wave velocity of rocks

In situ shear wave velocity is one of the most important parameters for evaluating dynamic elastic moduli and needs special energy sources for generation and receivers for detection. Identification of shear wave phase on a seismic record needs skill as it is not the first wave to arrive and is usually embedded in surface waves. To estimate shear wave velocity for site characterization and for p...

Using Intelligent Methods and Optimization of the Existing Empirical Correlations for Iranian Dead Oil Viscosity

Numerous empirical correlations exist for the estimation of crude oil viscosities. Most of these correlations are not based on the experimental and field data from Iranian geological zone. In this study several well-known empirical correlations including Beal, Beggs, Glasso, Labedi, Schmidt, Alikhan and Naseri were optimized and refitted with the Iranian oil field data. The results showed that ...
