1. Graphical representations of Ising and Potts models : Stochastic geometry of the quantum Ising model and the space-time Potts model
Abstract : HTML clipboard Statistical physics seeks to explain macroscopic properties of matter in terms of microscopic interactions. Of particular interest is the phenomenon of phase transition: the sudden changes in macroscopic properties as external conditions are varied. READ MORE

2. Cam Roller Contact
Abstract : The automotive industry and the design of engines are strongly ruled by performance andlegislation demands. First order aspects defining the main functions of a component are wellknown and new challenges appear at a lower scale. READ MORE

4. Time-domain modelling of curve squeal: a fast model for one- and two-point wheel/rail contact
Abstract : Curve squeal is a type of railway noise that may arise when a railway vehicle negotiates a relatively tight curve. A single frequency, corresponding to a wheel mode, dominates the radiated sound, which makes squeal a very tonal noise. READ MORE

5. On the influence of surface roughness on rolling contact forces
Abstract : Road vehicle tyres, railway wheels and ball bearings all generate rolling contact forces which are transferred within a finite area of contact between the rolling element and the substrate. Either it is visible or not for the human eye, a certain degree of roughness is always present on the contacting surfaces and it influences the generation of both vertical and lateral contactforces.
