Funciones(Cálculo diferencial)
(2011)
A mathematical function is a relationship in which each domain element corresponds to one and only one element of the range.
Report on mathematics teacher preparation in Ecuador
(Springer International Publishing, 2018)
The present volume is the third in the series of reports of the Capacity and Networking Project (CANP) of the International Commission on Mathematical Instruction (ICMI). It is the outcome of the intensive work that was ...
Walking another pathway: The inclusion of patterning in the pathways to mathematics model
(Elsevier Science Inc., 2022)
According to the Pathways to Mathematics model [LeFevre et al. (2010), Child Development, Vol. 81, pp. 1753-1767], children's cognitive skills in three domains-linguistic, attentional, and quantitative-predict concurrent ...
Can we heal Chagas infection?
(2014)
We present a model for the parasite-antibody dynamical competition between Trypanosoma rangeli and its antibodies during the acute phase of an infection in a mammal host. The model reproduces experimental data from murine ...
Compensatory fuzzy mathematical morphology
(Springer London Ltd, 2017-09)
In this paper, we propose the use of compensatory fuzzy logic to extend mathematical morphology (MM) operators to gray-level images, in a similar way than fuzzy logic is used, naming it compensatory fuzzy mathematical ...
Investigação histórica nas aulas de matemática: avaliação de duas experiências
(Universidade Federal do Rio Grande do NorteBRUFRNPrograma de Pós-Graduação em Ensino de Ciências Naturais e MatemáticaEnsino de Ciências Naturais e Matemática, 2008-02-26)
This study reflects on some procedural aspects about the development of mathematics learning from the experience with investigative activities concerning the
resolution of second degree equation, ...
Multiperiodic magnetic structures in Hubbard superlattices
(2002-08-01)
We consider fermions in one-dimensional superlattices (SL's), modeled by site-dependent Hubbard-U couplings arranged in a repeated pattern of repulsive (i.e., U>0) and free (U=0) sites. Density matrix renormalization group ...
