Finite Element Stochastic Analysis
Numerical models can be valuable tools in the prediction of seepage. The results can often be misleading if proper variational analysis is not performed. Measurement of the soil-water characteristic curve (SWCC) or saturated and unsaturated hydraulic conductivity information is often neglected or minimized. The modeller is therefore forced to develop a seepage model based on estimated soil prop...
متن کاملHigh dimensional model representation
Abstrakt: In practical applications of the control theory, there is lack of approximation techniques applicable to intractable dynamic-programming equations describing the optimality controller. In the paper, we consider use of the technique coming from chemistry and called high dimensional model representation (HDMR). Its main advantages are finite order of expansion and rapid convergence for ...
متن کاملBiomechanical Analysis of a Three Dimensional Finite Element Model
Low back pain has for long been associated with the lumbar spine biomechanics. A three dimensional model of segments L2 to L5 of lumbar spine is generated form CT images of a healthy human male. Hounsfield units of the image slices are used to derive material properties throughout the 3D model. This model is subjected to finite element analysis to study stresses developed during naturally found...

متن کاملAnalysis of High-order Approximations by Spectral Interpolation Applied to One- and Two-dimensional Finite Element Method
The implementation of high-order (spectral) approximations associated with FEM is an approach to overcome the difficulties encountered in the numerical analysis of complex problems. This paper proposes the use of the spectral finite element method, originally developed for computational fluid dynamics problems, to achieve improved solutions for these types of problems. Here, the interpolation n...
