Theoretical Dynamics of Experimental Populations of Introduced and Native Blowflies (Diptera: Calliphoridae)
Equilibrium dynamics in experimental populations of Chrysomya megacephala (F.) and C. putoria (Wiedemann), which have recently invaded the Americas, and the native species Cochliomyia macellaria (F.), were investigated ...
Basic ingredients for mathematical modeling of tumor growth in vitro: Cooperative effects and search for space
Based on the literature data from HT-29 cell monolayers, we develop a model for its growth, analogous to an epidemic model, mixing local and global interactions. First, we propose and solve a deterministic equation for the ...
Expansive movements in the development of mathematical modeling: Analysis from an Activity theory perspective
This research was conducted during an online continuing education course for mathematics teachers, whose core focus was modeling and applications. We studied the interactions of one group of two teachers, who worked ...
Mathematical Modelling and Didactics Sequences: a relationship of complementarity
(Unesp-dept MathematicaRio ClaroBrasil, 2008)
An in-depth analysis of the HIV-1/AIDS dynamics by comprehensive mathematical modeling
(PERGAMON-ELSEVIER SCIENCE LTDOXFORD, 2012)
This work presents major results from a novel dynamic model intended to deterministically represent the complex relation between HIV-1 and the human immune system. The novel structure of the model extends previous work by ...
Enriching elementary school mathematical learning with the steepest descent algorithm
The steepest descent (or ascent) algorithm is one of the most widely used algorithms in Science, Technology, Engineering, and Mathematics (STEM). However, this powerful mathematical tool is neither taught nor even mentioned ...
Dynamics of change of mathematics education in Brazil and a scenario of current research
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 ...
The role of software Modellus in a teaching approach based on model analysis
We discuss some results of a study carried out over the past 4 years to investigate the role of Modellus, a software package, in the development of an approach to teaching calculus for Biology majors. The central idea of ...
On The Nonlinear Self-adjointness And Local Conservation Laws For A Class Of Evolution Equations Unifying Many Models (vol 19, 350, 2014)
(ELSEVIER SCIENCE BVAMSTERDAM, 2016)
Deterministic mathematical model for the prediction of the as-cast macrostructure
(ESCOLA DE MINAS, 2008)
A multiphase deterministic mathematical model was implemented to predict the formation of the grain macrostructure during unidirectional solidification. The model consists of macroscopic equations of energy, mass, and ...
