Qualitative Modelling of Planar Robots

This study proposes an approach, the unit circle (UC), to qualitative modelling of a planar robot. A robot is described as a collection of constraints holding among time-varying, interval-valued variables. The UC representation is presented, the continuous motion of the end-effector is evaluated by the change of directions of qualitative angle and qualitative length. Analytical formulas of qual...

Radiation Heat Transfer in Planar SOFC Components: Application of the Lattice Boltzmann Method

Thermal radiation plays a very important role in the heat transfer combination through the various components of the SOFC fuel cell operating at high temperatures. Lattice Boltzmann method is used for treating conduction-radiation heat transfer in the electrolyte. The thermal radiation heat transfer is coupled to the overall energy conservation equations through the divergence of the local radi...

Modelling and analysis of planar cell polarity.

Planar cell polarity (PCP) occurs in the epithelia of many animals and can lead to the alignment of hairs, bristles, and feathers. Here, we present two approaches to modelling this phenomenon. The aim is to discover the basic mechanisms that drive PCP, while keeping the models mathematically tractable. We present a feedback and diffusion model, in which adjacent cell sides of neighbouring cells...

Modelling and Control of a novel SOFC-IC Engine Hybrid System

A novel configuration of a Solid Oxide Fuel Cell-Internal Combustion (SOFC-IC) engine is presented and a nonlinear dynamic model that captures the transient phenomena of this system is developed. A variable geometry turbocharger and a throttle present at the air inlet is used to regulate the interacting flows in the combined system. A controller is developed to regulate the output to demand spe...
