One of the features of the reform in school mathematics is that school mathematics should be made relevant to the learners. The incorporation of mathematical modelling in school mathematics is one of the ways that is offered to realise the relevance ideal. Ostensibly the inclusion of mathematical modelling will provide school learners opportunities to develop mathematical power i.e. the ability...

in the present study, the nonlinear model of non-newtonian blood flow in cosine-shape stenosed elastic artery is numerically examined. the model is carried out for axisymmetric, two-dimensional and fully developed blood flow. the vessel wall is assumed to be have time-dependent radius that is important factor for study of blood flow. the cosine-shape stenosis convert to rigid artery by using a ...

a mathematical modelling for more-winding single-phase transformer is presented. the incidence matrix-which gives the informations about the connection of the ends of the windings between the nodes-is multiplied leftside and rightside with the inverse of the inductance matrix of the more winding transformer. the result is a matrix which gives the relationship between nodes potentials and nodes ...

Chlamydiae are intracellular bacterial parasites that develop and multiply within mucosal cells of humans and animals and amongst the most common sexually transmitted disease worldwide. If left untreated, infection with Chlamydia can lead to serious outcomes such as infertility, ectopic pregnancy and blinding trachoma due to tissue scarring. There are currently no vaccines available for these m...

We give examples of how mathematical modelling is used to model processes in sport. We start by giving a general overview of areas currently employing mathematical tools to analyze the processes involved. We then go onto look in more detail at the use of mathematics to model the physiological response to exercise. It should also be noted that this area is not only fundamental to the science of ...
