This paper deals with the stability of the intersection of a given set $$ X\subset \mathbb{R}^{n}$$ with the solution, $$F\subset \mathbb{R}^{n}$$ , of a given linear system whose coefficients can be arbitrarily perturbed. In the optimization context, the fixed constraint set X can be the...

This paper proposes a new mathematical framework for the open pit mine planning problem, based on continuous functional analysis. The main challenge for engineers is to determine a sequence of nested profiles maximizing the net present value of the mining operation. The traditional models for...

Two feasibility studies using the earthworm (Eisenia fetida) and vermicompost in the processing and remediation of solid and liquid wastes with high metal content are presented: vermicompost as adsorbent substrate for remediation of wastewaters contaminated with metals; earthworms for...
