Multi-Scale Modelling of Gastric Electrophysiology
We have developed a multi-scale computational modelling framework for the study of gastric electrophysiology in health and disease. First, we have developed and validated two novel biophysically based models of Interstitial cell of Cajal and smooth muscle cell electrophysiology. Second, we have …

Multi-scale modelling of III-nitrides: from dislocations to the electronic structure
… to design a device with desired specifications, multilayered systems with varying composition (and thus material properties) are grown. Theoretical modelling is a useful tool for gaining understanding of various phenomena and materials properties. The scope of the present work is wide. It ranges …

Multi-scale modelling describing thermal behaviour of polymeric materials. Scalable lattice-Boltzmann models based upon the theory of Grmela towards refined thermal performance prediction of polymeric materials at micro and nano scales.
… have geometrical design features on a micrometer scale that must be transferred to the geometry of the produced part. The difficulties encountered due to very high shear and rapid heat transfer of these systems has motivated this investigation into the fundamental mathematics behind polymer heat …

Numerical modelling of electrodeposition process for printed circuit boards manufacturing
… the size of such a via is at the micrometer scale (this is why they are termed micro-vias). The most widely used technique for manufacturing micro-vias is electrodeposition of metal (e.g., copper), where the PCB is immersed into a plating cell filled with an electrolyte solution. Using …
