(2020-12-01)
In order to approximate and build a framework of Brazilian scientific production in Mathematics Education regarding the interface between Art and Mathematics, this article presents the results of a systematic literature ...
THE PROBLEM SOLVING IN THE SAO PAULO MATHEMATICAL CURRICULUM AND IN THE CADERNO DO ALUNO
(Univ Estadual Sudoeste Bahia, 2021-04-01)
In this paper we stablished an analysis about the treatment given to Problem Solving in the Mathematics Curriculum of the State of Sao Paulo and the material Caderno do Aluno, in High School. For the analysis of the ...
On the solution of mathematical programming problems with equilibrium constraints
(2002-02-01)
Mathematical programming problems with equilibrium constraints (MPEC) are nonlinear programming problems where the constraints have a form that is analogous to first-order optimality conditions of constrained optimization. ...
A NEW MATHEMATICAL MODEL FOR THE CUTTING STOCK/LEFTOVER PROBLEM
(Sociedade Brasileira de Pesquisa Operacional, 2015-12-01)
ABSTRACT This paper addresses the cutting stock/leftover problem (CSLP), which differs from the ordinary cutting stock problem (CSP) by retaining stock leftovers that can be cut in the future to meet new demands. Therefore, ...
MATHEMATICAL THINKING, CONCEPTUAL FRAMEWORKS: A REVIEW OF STRUCTURES FOR ANALYZING PROBLEM-SOLVING PROTOCOLS
(2010)
Recently, it has been considered important to reflect on the coincidences between the mathematical thinking of the School of Mathematics and the Discipline of Mathematics. It is widely accepted that a professional mathematician ...
Restoration of Electrical Distribution Systems Using a Relaxed Mathematical Model
(Springer, 2018-04-01)
This paper proposes a relaxed mathematical model to solve the restoration problem of radial and balanced electrical distribution systems. The mathematical model is a mixed-integer linear programming formulation that can ...
Conservation laws for non-potential operators
(1999-12-01)
A study was developed in order to build a function M invariant in time, by means of Hamiltonian's formulation, taking into account the equation associated to the problem, showing that starting from this function the equation ...
Mathematical models and a heuristic method for the multiperiod one-dimensional cutting stock problem
(2016-03-01)
The multiperiod cutting stock problem arises in the production planning and programming of many industries that have the cutting process as an important stage. Ordered items are required in different periods of a finite ...
Dynamics of change of mathematics education in Brazil and a scenario of current research
(2010-05-26)
Mathematics education in Brazil, if we consider what one may call the scientific phase, is about 30 years old. The papers for this special issue focus mainly on this period. During these years, many trends have emerged in ...
