Slope stability analysis is an enduring research topic in the engineering and academic sectors. Accurate prediction of the factor of safety (FOS) of slopes, their stability, and their performance is not an easy task. In this work, the adaptive neuro-fuzzy inference system (ANFIS) was utilized to build an estimation model for the prediction of FOS. Three ANFIS models were implemented including g...

Even though there exist lots of documents on Finite Element Strength Reduction Method, cohesion and internal friction angle in these materials are reduced through the same reduction factor, which fails to reflect either of their safe reserving quality or the quality to precisely match slope failure process and mechanism. As is known, the exterior angle circumcircle yield criterion DP1 of the ge...

The dynamic and friction parameters of a redundantly actuated parallel manipulator are identified by using the Weighted Least Square (WLS) method. The dynamic model with nonlinear friction is formulated in the joint space for the parallel manipulator, and it is expressed in its linear matrix form with respect to the dynamic and friction parameters. In the WLS method, the difference algorithm of...

Roots can be seen as natural soil reinforcement material. The prediction and quantitative evaluation of the shear strength root-permeated is focus vegetation slope protection, in which bonding effect root–soil interface key factor. Taking roots Chinese fir trees an example, resistance test direct with different root area ratios inclination angles were carried out. results indicated that could q...

Atomistic simulations of double-walled carbon nanotubes (DWCNTs) as rotational bearings were performed. Molecular mechanics (MM) calculations show that the interlayer energy surface of the bearings is nearly flat. Thermal effects on the bearings were studied with molecular dynamics (MD) simulations at finite temperature. These simulations show that the interlayer corrugation against rotation, a...

Shear strength of aggregates and the bulk soil matrix in two Haploxeroll of central Chile was assessed in order to determine: (1) the effect of previous tillage on shear parameters between aggregates and in the soil matrix and (2) the effects of structure development on differences between dry-wet mechanical parameters. Undisturbed soil cylinders and single aggregates (0-10 cm layer) were colle...
