This study adopts Multivariate Adaptive Regression Spline (MARS) and Least Square Support Vector Machine (LSSVM) for prediction of undrained shear strength (su ) of clay, based Cone Penetration Test (CPT) data. Corrected cone resistance (qt ), vertical total stress (σv ), hydrostatic pore pressure (u0 ), pore water pressure at the cone tip (u1 ), and pore water pressure just above the cone base...

With the recent advances in biogeotechnics field and specifically microbially induced calcite precipitation (MICP), cone penetration testing (CPT) has become a valuable tool to overcome challenges associated with intact sampling of improved soils, evaluate spatial extent magnitude applied MICP treatment, assess consequential improvement engineering properties. Although CPT tip resistance (qc) c...

The study aims to construct a framework for CPT based ultimate pile capacity calculation cohesionless soils with random field theory. Cone tip resistance (qc) was taken as the spatially varying parameter constant mean and changing coefficients of variation. profiles were simulated generations, single (Qu) calculated these simulations. influence spatial variation qc on Qu investigated. proposed ...

In order to quantify the P- and S-wave velocities, dynamic elastic moduli bearing capacity of shallow alluvial sediments, seismic refraction cone penetration test (CPTu) soundings were carr...

A computer simulation of cone penetration in layered soil was carried out using axisymmetric finite element (FE) to investigate soil deformation and soil hardpan prediction during cone penetration. The FE analysis was performed in ABAQUS, commercially available FE package. Soil was considered as a non­ linear elastic plastic material modeled using Drucker Prager material model with hardening op...

STATEMENT OF PROBLEM Most failures of root canal treatments are caused by bacteria. Studies showed that the most common cause of endodontic failures were the incomplete obturation of the root canal and the lack of adequate apical seal. Some in-vitro methods are used to estimate sealing quality, generally by measuring microleakage that allows the tracer agent to penetrate the filled canal. PUR...
