This paper deals with the results coming from the research activity of the SECOSUD Phase II, called ?Conservation and equitable use of biological diversity in the SADC region (Southern African Development Community) a project supported by the Italian Ministry of Foreign Affairs in the SADC [1]. In the framework of this project they have been investigated groundwater resources and shallow ones present in the buffer zone of National Limpopo Park, in the aim of better support water demand in the villages, rising in t...

The solution of subsoil-structure interaction is affected by several factors as a choice of interaction model, influence of physical-nonlinear behaviour of structure and co-effects of the upper structure and the foundation structure. The subsoil-structure interaction can be solve by application of analytical methods or numerical methods - eg. Finite Element Method (FEM) or Boundary Element Method (BEM). FEM was used for numerical analysis performed in this article. Many different interaction models implemented in ...

Constrained optimization problems are problems for which a function f (x) is to be minimized or maximized subject to constraints ? (x) . Here f : Rn ? R is called the objective function and F(x) is a Boolean-valued formula. In Mathematica the constraints ? (x) can be an arbitrary Boolean combination of equations g (x) ?0 , weak inequalities g (x) >=0, strict inequalities g(x)> 0, x is integer and x>0 statements. A point u ? Rn is said to be a global minimum of f subject to constraints F if u satisfies the constrai...

This paper deals with the first results coming from the research activity of the SECOSUD Phase II, called ?Conservation and equitable use of biological diversity in the SADC region (Southern African Development Community) a project supported by the Italian Ministry of Foreign Affairs in the SADC [1]. The goal of this tiered study is to give an integrated view of three focus themes inside the area of Limpopo National Park, in Limpopo River Basin: groundwater, climate change, biodiversity. Limpopo National Park is o...
