• Developing modeling competency for primary students through real-life context in natural number topic comparison in Germany, Singapore and Vietnam

    Developing modeling competency for primary students through real-life context in natural number topic comparison in Germany, Singapore and Vietnam

    Mathematical modeling is one of the competencies that have been focused in the curriculum of many countries in the world such as Australia, Germany, Singapore and USA. In Vietnam, the Mathematics curriculum promulgated in 12/2018 clarified that modeling competency would be one of the domain-specific competencies that contribute to the formation and development of the mathematical competency in particular, and numeracy in general. In the new...

  • Experiences of improving mathematical communication competence for Vietnamese secondary school through theme “solving problem by setting up system of equations”

    Experiences of improving mathematical communication competence for Vietnamese secondary school through theme “solving problem by setting up system of equations”

    This paper aims to discuss our experiences of promoting mathematical communication competence for students at secondary school in Vietnam. In this research, we applied the qualitative research that consists of the designed experiment and the participant’s observation method. From result experiment, we show out detail about Vietnamese students not only skills solving productivity problem but also mathematical communication competence....

  • Mathematical modelling from the cognitive point of view, the transition from implicit model to explicit model

    Mathematical modelling from the cognitive point of view, the transition from implicit model to explicit model

    Thecognitive aspect of mathematical modeling competencehas been of interest in the mathematics education community. From the cognitive point of view, the individual's behavior and problem-solving abilities have a strong connection with the inner cognitive activities. We will present BorromeoFerri’s diagram of cognitive mathematical modeling, including the transformation from an implicit model to an explicit model. We then describe one group...

  • Periodic solutions to a class of differential variational inequalities in banach spaces

    Periodic solutions to a class of differential variational inequalities in banach spaces

    In this work, we consider a model formulated by a dynamical system and an elliptic variational inequality. We prove the solvability of initial value and periodic problems. Finally, an illustrative example is given to show the applicability of our results.

  • A note on stable solutions of a sub-elliptic system with singular nonlinearity

    A note on stable solutions of a sub-elliptic system with singular nonlinearity

    In this paper, we study a system of the form ( ∆λu = v ∆λv = −u −p in R N , where p > 1 and ∆λ is a sub-elliptic operator. We obtain a Liouville type theorem for the class of stable positive solutions of the system.

  • Training pre-service teacher competence to integrate interdisciplinary knowledge to solve problems in practice through the integrated topic in general physics module

    Training pre-service teacher competence to integrate interdisciplinary knowledge to solve problems in practice through the integrated topic in general physics module

    In higher education, it is essential to change teaching method toward the learnercentered orientation. Teaching through topics with practical content is one of the preferred options today. Problems in real-life contain complex elements that are almost impossible to explain by just one subject. The paper presents the method of organizing thematic teaching to foster pedagogical students’ ability to integrate interdisciplinary knowledge so that...

  • Ultimate stability of nonlinear time-varying systems with multiple delays

    Ultimate stability of nonlinear time-varying systems with multiple delays

    The ultimate stability of nonlinear time-varying systems with multiple delays and bounded disturbances are investigated in this paper. Based on some comparison techniques via differential inequalities, explicit delay-independent conditions are derived for determining an ultimate bound such that all state trajectories of the system converge exponentially within that bound. The obtained results also guarantee exponential stability of the system...

    Optimization of a saturated gas plant: Meticulous simulation-based optimization – A case study

    An optimization-simulation strategy has been applied by coupling a commercial process simulator (Aspen HYSYS ) with a programming tool (MATLAB ) to produce a precise steady state simulationbased optimization of a whole green-field saturated gas plant as a real case study. The plant has more than 100-components and comprises interacting three-phase fractionation towers, pumps, compressors and exchangers. The literature predominantly uses this...
