Continuous phase transitions in spin systems can be formulated as percolation of suitably defined clusters. We review this equivalence and then discuss how in a similar way, the color deconfinement transition in SU(2) gauge theory can be treated as a percolation phenomenon. In the presence of an external field, spin systems cease to show thermal critical behavior, but the geometric percolation ...

New techniques were utilized to measure burst speed and distance running capacity in six species of lizards and to examine the thermal dependence of these behavioural capacities. These behaviours were repeatable among groups of animals within a species, within a group during the experiments, and among individuals of a group. Burst speeds averaged 130 to 150 m/min for active species, with some i...

The designer's preoccupation to reduce the energy needs and get a better thermal quality of ambiances helped in the development of several packages simulating the dynamic behaviour of buildings. This paper shows the adaptation of a method of thermal analysis, the nodal analysis, linked to the case of building's thermal behaviour. We take successively an interest in the case of conduction into a...

Simulation codes of thermal behaviour could significantly improve housing construction design. Among the existing software, CODYRUN and TRNSYS are calculations codes of different conceptions. CODYRUN is exclusively dedicated to housing thermal behaviour, whereas TRNSYS is more generally used on any thermal system. The purpose of this article is to compare these two instruments in two different ...

We have studied by Monte Carlo simulations the thermal behaviour of a small (N = 13 particles) cluster described by a Heisenberg model, including nearestneighbour ferromagnetic interactions and radial surface anisotropy, in an applied magnetic field. We have studied three different lattice structures: hexagonal close packed, face centered cubic and icosahedral. We show that the zero-field therm...

Topics in Designing Low Thermal Expansion Lattices at the Microscale John Chu Master of Applied Science Graduate Department of Aerospace Science and Engineering University of Toronto 2011 Microscale bi-material lattices with near zero thermal expansion are designed to create a thermally stable optical surface for applications in a space telescope. To facilitate the design, the thermal expansion...
