A Priori and a Posteriori Error Analyses of an Augmented HDG Method for a Class of Quasi-Newtonian Stokes Flows
(Springer, 2016-12)In a recent work we developed a new hybridizable discontinuous Galerkin (HDG) method for a class of nonlinear Stokes models arising in quasi-Newtonian fluids. The approach there uses the incompressibility condition to ... -
A priori and a posteriori error analyses of an HDG method for the Brinkman problem
(Elsevier, 2018-01-15)In this paper we introduce and analyze a hybridizable discontinuous Galerkin (HDG) method for the linear Brinkman model of porous media flow in two and three dimensions and with non-homogeneous Dirichlet boundary conditions. ... -
Identification of characteristics of didactic and meta-didactic mathematical knowledge of novice and expert teachers when reflecting on class episodes
(Sriwijaya University, 2023-02-19)This article describes the didactic analysis carried out by an expert teacher and a novice teacher, based on the didactic suitability criteria (DSC) of the Onto Semiotic Approach (OSA) when analyzing episodes of a high ... -
TPACK Model: Teachers’ Perceptions of Their Technological Competence When Conducting an Experimental Virtual Lesson in the Context of Covid-19
(Ulbra - Universidade Luterana do Brasil, 2022-08-28)Background: One of the current concerns in the face of the changes and challenges imposed by the COVID-19 pandemic is the quality of the education received in non-traditional environments such as virtual or hybrid teaching. ...
