Pork production technology optimization based on mathematical modelling

Teaching and Learning Mathematical Modelling with Technology

In the last few decades, there have been abundant discussions among mathematicians and mathematics educators on promoting mathematical modelling (a process of using mathematics to tackle real world problems) as a classroom practice. Mathematics educators and curriculum planners have been advocating the teaching of mathematical modelling in schools for some time now. Despite the consensus on its...

A reverse logistics chain mathematical model for a sustainable production system of perishable goods based on demand optimization

Sustainability in the supply chain means pushing the supply chain to focus on social, economic and environmental aspects, and addressing the existing problems in the traditional supply chain. Considering the importance of evaluating supply chain networks, especially in the field of perishable commodities, this paper aimed to design a mathematical model for the reverse supply chain of perishable...

Mathematical Modelling of Sound Production in Birds

In this thesis, the physics of birds phonation is discussed using a two-mass models approach and the theory of nonlinear dynamics. Two-mass models of the human larynx (rescaled two-mass model and trapezoidal model) have been adapted to the dimension of the avian syrinx to study pressure onset, control of harmonic overtones and “registers” of the sound radiated by the birds vocal organ (syrinx) ...

Mathematical Modelling and Simulation Research of Thermal Engraving Technology Based on PMMA Material

We proposed a thermal engraving technology based on heat transfer theory and polymer rheology in microfluidic field. Then, we established a 3D model of the thermal engraving process based on polymethyl methacrylate (PMMA) material. We could employ the model to analyze the influence of temperature and speed on microchannel processing through the finite element simulation. Thus, we gained the opt...
