DOI: 10.1007/s10763-020-10123-4
Abstract: We analyzed the written answers and explanations by 26 Brazilian high-school students who attempted to solve double and multiple proportionality problems using the cross-product algorithm. We focused on students’ awareness of the scalar and functional… read more here.

DOI: 10.3390/axioms12030270
Abstract: In this study, we suggest a new iterative family of iterative methods for approximating the roots with multiplicity in nonlinear equations. We found a lack in the approximation of multiple roots in the case that… read more here.

DOI: 10.4018/ijepr.321156
Abstract: While big cities are expected to exercise cost-effective, evidence-based planning, many are under reactive management, facing simultaneous problems and limited resources. This project develops a proof-of-concept workflow for the automatic monitoring of physical urban problems… read more here.
