The use of temporary hip prosthesis made orthopedic cement (spacer) in conjunction with antibiotics became a widespread method used for treating prosthetic infections despite the fact that this makes bone (PMMA) more fragile. necessity to incorporate reinforcement is therefore crucial strengthen cement. In study, validated Finite Element Modelling (FEM) was analyze behavior spacers. This FEM mo...

Quasi-regression is introduced for approximation of functions on the unit cube in s dimensions. It is computationally eecient, compared to kriging, for problems requiring a large number of function evaluations. This paper describes how to implement quasi-regression and shows how to estimate the approximation error using the same data used to build the approximation. Four example functions are i...
